18 ± 0.01 to 1.31 ± 0.03 and from 13.5 ± 7.0 to 24.3 ± 13.5 μg m-3, respectively, and were greater than those of fresh soot (1.12 ± 0.02 and 8.0 ± 0.8 μg m-3), but also showed non-monotonic trends, suggesting the formation of BrC during O3 aging. Comparative results indicated that AAE might be a better BrC indicator for soot than ΔC. The non-monotonic trend was tentatively explained by changes in organic carbon, oxygenated functional groups and conjugated structures, as well as polycyclic aromatic hydrocarbon (PAH) degradation and oxygenated PAH formation. The relative intensities of oxidative formation and degradation of chromophores may determine BrC evolution during O3 aging. This study will be useful for clarifying BrC evolution in the atmosphere and estimating its radiative forcing.Sensing of pathogens by specialized receptors is the hallmark of the innate immunity. #link# Innate immune response also mounts a defense response against various allergens and pollutants including particulate matter present in the atmosphere. Air pollution has been included as the top threat to global health declared by WHO which aims to cover more than three billion people against health emergencies from 2019 to 2023. https://www.selleckchem.com/products/2-d08.html (PM), one of the major components of air pollution, is a significant risk factor for many human diseases and its adverse effects include morbidity and premature deaths throughout the world. Several clinical and epidemiological studies have identified a key link between the PM existence and the prevalence of respiratory and inflammatory disorders. However, the underlying molecular mechanism is not well understood. Here, we investigated the influence of air pollutant, PM10 (particles with aerodynamic diameter less than 10 μm) during RNA virus infections using Highly Pathogenic Avian Influenza (HPAI) - H5N1 virus. We thus characterized the transcriptomic profile of lung epithelial cell line, A549 treated with PM10 prior to H5N1infection, which is known to cause severe lung damage and respiratory disease. We found that PM10 enhances vulnerability (by cellular damage) and regulates virus infectivity to enhance overall pathogenic burden in the lung cells. Additionally, the transcriptomic profile highlights the connection of host factors related to various metabolic pathways and immune responses which were dysregulated during virus infection. Collectively, our findings suggest a strong link between the prevalence of respiratory illness and its association with the air quality.In this paper, a novel integral reinforcement learning (IRL)-based event-triggered adaptive dynamic programming scheme is developed for input-saturated continuous-time nonlinear systems. By using the IRL technique, the learning system does not require the knowledge of the drift dynamics. Then, a single critic neural network is designed to approximate the unknown value function and its learning is not subjected to the requirement of an initial admissible control. In order to reduce computational and communication costs, the event-triggered control law is designed. The triggering threshold is given to guarantee the asymptotic stability of the control system. Two examples are employed in the simulation studies, and the results verify the effectiveness of the developed IRL-based event-triggered control method.We present DANTE, a novel method for training neural networks using the alternating minimization principle. DANTE provides an alternate perspective to traditional gradient-based backpropagation techniques commonly used to train deep networks. It utilizes an adaptation of quasi-convexity to cast training a neural network as a bi-quasi-convex optimization problem. We show that for neural network configurations with both differentiable (e.g. sigmoid) and non-differentiable (e.g. ReLU) activation functions, we can perform the alternations effectively in this formulation. DANTE can also be extended to networks with multiple hidden layers. In experiments on standard datasets, neural networks trained using the proposed method were found to be promising and competitive to traditional backpropagation techniques, both in terms of quality of the solution, as well as training speed.This paper expatiates the stability and bifurcation for a fractional-order neural network (FONN) with double leakage delays. Firstly, the characteristic equation of the developed FONN is circumspectly researched by employing inequable delays as bifurcation parameters. Simultaneously the bifurcation criteria are correspondingly extrapolated. Then, unequal delays-spurred-bifurcation diagrams are primarily delineated to confirm the precision and correctness for the values of bifurcation points. Furthermore, it lavishly illustrates from the evidence that the stability performance of the proposed FONN can be demolished with the presence of leakage delays in accordance with comparative studies. Eventually, two numerical examples are exploited to underpin the feasibility of the developed theory. The results derived in this paper have perfected the retrievable outcomes on bifurcations of FONNs embodying unique leakage delay, which can nicely serve a benchmark deliberation and provide a comparatively credible guidance for the influence of multiple leakage delays on bifurcations of FONNs.The current state-of-the-art object recognition algorithms, deep convolutional neural networks (DCNNs), are inspired by the architecture of the mammalian visual system, and are capable of human-level performance on many tasks. As they are trained for object recognition tasks, it has been shown that DCNNs develop hidden representations that resemble those observed in the mammalian visual system (Razavi and Kriegeskorte, 2014; Yamins and Dicarlo, 2016; Gu and van Gerven, 2015; Mcclure and Kriegeskorte, 2016). Moreover, DCNNs trained on object recognition tasks are currently among the best models we have of the mammalian visual system. This led us to hypothesize that teaching DCNNs to achieve even more brain-like representations could improve their performance. To test this, we trained DCNNs on a composite task, wherein networks were trained to (a) classify images of objects; while (b) having intermediate representations that resemble those observed in neural recordings from monkey visual cortex. Compared with Dnal for training DCNNs.The characterization of DOM and its effect on heavy metal solubility in soils have been widely concerned, while few concerns on the phytostabilization of multi-metal contaminated soils. A pot experiment was performed to characterize dissolved organic matter (DOM) in the rhizosphere of the mining ecotype (ME) and non-mining ecotype (NME) of Athyrium wardii (Hook.) when exposed to Cd and Pb simultaneously, and investigate its effect on Cd and Pb solubility in soils. The ME presented more DOM in the rhizosphere when exposed to Cd and Pb simultaneously than that exposed to single Cd or Pb, and also than the NME. link2 The acid fractions (hydrophilic acid, hydrophobic acid) and hydrophilic fractions (hydrophilic acid, hydrophilic neutral, and hydrophilic base) were the dominant parts of DOM in the ME rhizosphere. The ME presented more acid and hydrophilic fractions in the rhizosphere when exposed to Cd and Pb simultaneously. Meanwhile, there were more O-H, C-O, N-H and C-H, assigned to carboxylic groups, phenolic groups, hydroxyl groups, and/or amino groups, present in DOM from the rhizosphere of ME when exposed to Cd and Pb simultaneously. These results highlighted the acid characteristics of DOM in the rhizosphere of ME when exposed to Cd and Pb simultaneously. DOM in the rhizosphere of ME thereby showed greater complexation degree for Cd (68%) and Pb (77%), thus showing greater ability to enhance Cd and Pb solubility in soils when exposed to Cd and Pb simultaneously. This is thereby considered to be one of the key processes for enhancing Cd and Pb uptake by the ME when exposed to Cd and Pb simultaneously.Biodiesel is considered as a valuable and less toxic alternative to diesel. However, cellular and molecular effects of repeated exposure to biodiesel emissions from a recent engine equipped with a diesel particle filter (DPF) remain to be characterized. To gain insights about this point, the lung transcriptional signatures were analyzed for rats (n = 6 per group) exposed to filtered air, 30% rapeseed biodiesel (B30) blend or reference diesel (RF0), upstream and downstream a DPF, for 3 weeks (3 h/day, 5 days/week). Genomic analysis revealed a modest regulation of gene expression level (lower than a 2-fold) by both fuels and a higher number of genes regulated downstream the DPF than upstream, in response to either RF0 or to B30 exhaust emissions. The presence of DPF was found to notably impact the lung gene signature of rats exposed to B30. The number of genes regulated in common by both fuels was low, which is likely due to differences in concentrations of regulated pollutants in exhausts, notably for compound organic volatiles, polycyclic aromatic hydrocarbons, NO or NOx. Nevertheless, we have identified some pathways that were activated for both exhaust emissions, such as integrin-, IGF-1- and Rac-signaling pathways, likely reflecting the effects of gas phase products. By contrast, some canonical pathways relative to "oxidative phosphorylation" and "mitochondrial dysfunction" appear as specific to B30 exhaust emission; the repression of transcripts of mitochondrial respiratory chain in lung of rats exposed to B30 downstream of DPF supports the perturbation of mitochondria function. This study done with a recent diesel engine (compliant with the European IV emission standard) and commercially-available fuels reveals that the diesel blend composition and the presence of an after treatment system may modify lung gene signature of rats repeatedly exposed to exhaust emissions, however in a rather modest manner.A cross-sectional population-based study was conducted in order to evaluate the association of sleep characteristics with anxiety disorders using self-reported questionnaires and taking into account several socio-demographic, lifestyle and health related characteristics. 957 participants between 19 and 86 years old were enrolled in our study. Anxiety symptoms were assessed using the Zung Self-rating Anxiety Scale. Participants self-reported their daily sleep habits and filled in the following scales Epworth Sleepiness Scale, Athens Insomnia Scale, Pittsburgh Sleep Quality Index and Berlin Questionnaire. Overall prevalence of anxiety was 33.6%. Anxiety symptoms were more prominent among minority groups. link3 Subjects with anxiety reported shorter sleep duration and reduced sleep efficiency. After adjusting for all possible confounders, they were five times more likely to exhibit short sleep duration (≤6h) and 0.60 times less likely long sleep duration (>8h). These relations remained significant in both genders, but were more pronounced among men. Moreover, anxiety was associated with excessive daytime sleepiness, insomnia, poor sleep quality and higher risk of obstructive sleep apnea (OSA). Results highlight the association of sleep disturbances with anxiety disorders and call for conduction of larger scale prospective studies in order to assess causality on the clinically important relationship between sleep characteristics and anxiety disorders.

Purpose; For shoot-through proton treatments, like FLASH radiotherapy, there will be protons exiting the patient which can be used for proton portal imaging (PPI), revealing valuable information for the validation of tumor location in the beam's-eye-view at native gantry angles. However, PPI has poor inherent contrast and spatial resolution. To deal with this issue, we propose a deep-learning-based method to use kV digitally reconstructed radiographs (DRR) to improve PPI image quality. Method; We used a residual generative adversarial network (GAN) framework to learn the nonlinear mapping between PPIs and DRRs. Residual blocks were used to force the model to focus on the structural differences between DRR and PPI. To assess the accuracy of our method, we used 149 images for training and 30 images for testing. PPIs were acquired using a double-scattered proton beam. The DRRs acquired from CT acted as learning targets in the training process and were used to evaluate results from the proposed method using a six-fold cross-validation scheme. Results; Qualitatively, the corrected PPIs showed enhanced spatial resolution and captured fine details present in the DRRs that are missed in the PPIs. The quantitative results for corrected PPIs show average normalized mean error (NME), normalized mean absolute error (NMAE), peak signal-to-noise ratio (PSNR) and structural similarity (SSIM) index of -0.1%, 0.3%, 39.14 dB, and 0.987, respectively. Conclusion; The results indicate the proposed method can generate high quality corrected PPIs and this work shows the potential to use a deep-learning model to make PPI available in proton radiotherapy. This will allow for beam's-eye-view (BEV) imaging with the particle used for treatment, leading to a valuable alternative to orthogonal x-rays or cone-beam CT for patient position verification.The displacement of tumor bed walls during oncoplastic breast surgery (OBS) decreases the accuracy of using surgical clips as the sole surrogate for tumor bed location. This highlights the need for better communication of OBS techniques to radiation oncologists. To facilitate OBS practice and investigate clip placement reliability, a realistic silicone-based breast phantom was constructed with components emulating a breast parenchyma, epidermis, areola, nipple, chest wall, and a tumor. OBS was performed on the phantom and surgical clips were placed to mark the tumor bed. The phantom was imaged with CT, MRI, and ultrasound (US). The parenchyma's signal-to-noise ratio (SNR) and clips to parenchyma's contrast-to-noise ratio (CNR) were measured. The phantom's CT Hounsfield Unit (HU), relative electron density (RED), and mass density were determined. 6 and 10 MV photon beam attenuation measurements were performed in phantom material. The Young's Modulus and ultimate tensile strength (UTS) of the phantom parenchyma and epidermis were measured. https://www.selleckchem.com/products/ly364947.html Results showed that the breast phantom components were visible on all imaging modalities with adequate SNR and CNR. The phantom's HU is 130 ± 10. The RED is 0.983. Its mass density is 1.01 ± 0.01 g cm-3. Photon attenuation measurements in phantom material were within 1% of those in water. The Young's Moduli were 13.4 ± 4.2 kPa (mechanical) and 30.2 ± 4.1 kPa (US elastography) for the phantom parenchyma. The UTS' were 0.05 ± 0.01 MPa (parenchyma) and 0.23 ± 0.12 MPa (epidermis). link2 We conclude that the phantom's imaging characteristics resemble a fibroglandular breast's and allow clear visualization of high-density markers used in radiation therapy. The phantom material is suitable for dose measurements in MV photon beams. Mechanical results confirmed the phantom's similarity to breast tissue. The phantom enables investigation of surgical clip displacements pre- and post-OBS, and is useful for radiation therapy quality assurance applications.To treat cancer, knowledge of mechanical parameters can be essential. This study proposes a new approach for estimating hydraulic conductivity (k) and hydraulic conductivity ratio (α) of a living tissue, based on inverse methods, allowing tissue parameter estimation using only a limited set of measurements. First, two population-based algorithms (Levenberg-Marquardt (LM) method and conjugate gradient (CG) method) and two gradient-based algorithms (genetic algorithm (GA) and particle swarm optimization (PSO) algorithm) are considered, and a comparative study between these different inverse methods is performed to determine which methods have a good performance in terms of convergence rate and stability. CG method is shown to perform well in the case of noise-free input data; however, in the case of noisy input data, it fails to converge. The other three methods (LM, GA, and PSO) converge with estimation errors less then 10% in both noise-free and noisy input data, suggesting their utility to tackle this problem. In the second part, the effectiveness and good accuracy of these robust algorithms (LM, GA, and PSO) are validated with experimental results. The hydraulic conductivity and hydraulic conductivity ratio of a specific living tumor tissue are then estimated for mammary adenocarcinoma (R3230AC). Moreover, assuming measurement of only one-point interstitial pressure inside the tumor, the effect of the location of this one-point on estimation accuracy of hydraulic conductivity is investigated. We show that estimation errors for points measured near the surface and center of the tumor are greater than at other points.Sonography, elastography, sonoelastography are ultrasound imaging techniques commonly used in the clinical practice for the diagnosis of many pathological conditions. These highly reliable, non-invasive methods use high frequency, elastic pressure waves (ultrasounds) to interrogate the internal structure of biological tissues and organs, and the continuum mechanics hypothesis to reconstruct, from the output of the system, the biophysical characteristics of the samples. Nevertheless, continuum mechanics disregards the discrete nature of tissues and organs, resulting in an inability for the model to describe some important tissue biophysical characteristics such as the cell size and their spatial layout. Here, we used the theory of doublet mechanics - a discrete nano-mechanical field theory - to model the propagation of ultrasounds in a multilayered biological tissue. We found that the output of the model exhibits a very high sensitivity to the macro and micro characteristics of the tissue, including cell size. We used results from the model to correlate the internal structure of the samples to the reflection coefficient, i.e. the continuum level response of the system. This model, and its more sophisticated evolutions that will be developed over time, can complement traditional ultrasound imaging, and provide ways to analyze non-invasively living tissues with a resolution inaccessible to conventional techniques of analysis, including positron emission tomography, computer tomography, and magnetic resonance.Although micro-computed tomography (micro-CT) images have high contrast for bone or air, between soft tissues the contrast is typically low. To overcome this inherent issue, attenuating exogenous contrast agents are used to provide contrast enhancement in the vasculature and abdominal organs. The aim of this study is to measure the contrast enhancement time course for a gold nanoparticle blood-pool contrast agent and use it to perform cardiac-gated 4D micro-CT scans of the heart. Six healthy female C57BL/6 mice were anesthetized and imaged after receiving an injected dose of MVivo gold nanoparticle blood-pool contrast agent. Following the injection, we performed micro-CT scans at 0, 0.25, 0.5, 0.75, 1, 2, 4, 8, 24, 48 and 72 h. The mean CT number was measured for 7 different organs. No contrast enhancement was noticed in the bladder, kidneys or muscle during the time-course study. However, it clearly appears that the contrast enhancement is high in both right ventricle and vena cava. To perform cardiac-gated imaging, either the gold nanoparticle agent (n = 3) or an iodine-based (n = 3) contrast agent was introduced and images representing 9 phases of the cardiac cycle were obtained in 6 additional mice. A few typical cardiac parameters were measured or calculated, with similar accuracy between the gold and iodinated agents, but better visualization of structures with the gold agent. The MVivo Au contrast agent can be used for investigations of cardiac or vascular disease with a single bolus injection, with an optimal cardiac imaging window identified during the first hour after injection, demonstrating similar image quality to iodinated contrast agents and excellent measurement accuracy. Furthermore, the long-lasting contrast enhancement of up to 8 h can be very useful for scanning protocols that require longer acquisition times.
Motor imagery can be used as an adjunct to traditional stroke rehabilitation therapies for individuals who have hand and arm impairment resulting from their stroke. The provision of neurofeedback during motor imagery allows individuals to receive real time information regarding their motor imagery-related brain activity. However, the equipment required to administer this feedback is expensive and largely inaccessible to many of the individuals who could benefit from it. Available EEG-based technology provides an accessible, low-cost, wireless alternative to traditional neurofeedback methods, with the tradeoff of lower gain and channel count resulting in reduced signal quality. This study investigated the efficacy of this wireless technology for the provision of motor imagery-related neurofeedback.

Twenty-eight healthy individuals participated in a 2-group, double-blinded study which involved imagining performing a unimanual button pressing task while receiving neurofeedback that is either a direct transfomented in a clinical setting.
Our main findings replicated previous results with research-grade equipment indicating that there is potential for introducing this wireless technology for the provision of neurofeedback. link3 Given the marginal longitudinal effect of neurofeedback in our study, further study is required to address the limitations associated with this technology before our protocol can be implemented in a clinical setting.
A promising application of BCI technology is in the development of personalized therapies that can target neural circuits linked to mental or physical disabilities. Typical BCIs, however, offer limited value due to simplistic designs and poor understanding of the conditions being treated. Building BCIs on more solid grounds may require the characterization of the brain dynamics supporting cognition and behavior at multiple scales, from single-cell and local field potential (LFP) recordings in animals to non-invasive electroencephalography (EEG) in humans. Despite recent efforts, a unifying software framework to support closed-loop studies in both animals and humans is still lacking. The objective of this paper is to develop such a unifying neurotechnological software framework.

Here we develop the Simulink for Brain Signal Interfaces library (SimBSI). Simulink is a mature graphical programming environment within MATLAB that has gained traction for processing electrophysiological data. SimBSI adds to this ecosystem 1) advanced human EEG source imaging, 2) cross-species multimodal data acquisition based on the Lab Streaming Layer library, and 3) a graphical experimental design platform.

This review provides a comprehensive overview of the current AI integration in MRgRT from a medical physicist's perspective. Medical physicists are expected to be major actors in solving new tasks and in taking new responsibilities their traditional role of guardians of the new technology implementation will change with increasing emphasis on the managing of AI tools, processes and advanced systems for imaging and data analysis, gradually replacing many repetitive manual tasks.Transcranial Magnetic Stimulation (TMS) is used reliably as an alternative method in the treatment of a number of treatment-resistant psychiatric disorders. However, information about the daily practice is limited. In this article, we aim to report and discuss the 10-years results of a clinic that applies TMS to treatment-resistant psychiatric disorders. This naturalistic study is a retrospective review of data routinely collected from patients undergoing TMS between 2010 and 2020. A total of 284 patients with diagnoses of major depressive disorder (MDD), obsessive-compulsive disorder, generalized anxiety disorder, and post-traumatic stress disorder (PTSD) were included in the study. The mean age of the participants was 40.49±12.64 years. In general, when the responses of all patients were examined, 26.1% were evaluated as response, 29.2% as partial response, and 44.7% as inadequate response. It has been determined that MDD responds to treatment better than other disorders. Regardless of the diagnosis, a significant relationship was found between response and age. The multivariate logistic regression analysis suggested that patients with improvement from TMS were less likely to have advanced age and not to have been diagnosed with PTSD. The idea that TMS may be useful for some patients, but not every patient, is supported.COVID-19, and efforts to mitigate its spread, are creating extensive mental health problems. Experts have speculated the mental, economic, behavioral, and psychosocial problems linked to the COVID-19 pandemic may lead to a rise in suicide behavior. However, a quantitative synthesis is needed to reach an overall conclusion regarding the pandemic-suicide link. In the most comprehensive test of the COVID-19-suicidality link to date, we meta-analyzed data from 308,596 participants across 54 studies. Our results suggested increased event rates for suicide ideation (10.81%), suicide attempts (4.68%), and self-harm (9.63%) during the COVID-19 pandemic when considered against event rates from pre-pandemic studies. Moderation analysis indicated younger people, women, and individuals from democratic countries are most susceptible to suicide ideation during the COVID-19 pandemic. Policymakers and helping professionals are advised that suicide behaviors are alarmingly common during the COVID-19 pandemic and vary based upon age, gender, and geopolitics. Strong protections from governments (e.g., implementing best practices in suicide prevention) are urgently needed to reduce suicide behaviors during the COVID-19 pandemic.
The objective of the study was to analyze the auditory brainstem response (ABR) test results of adolescents with normal hearing threshold who have subjective tinnitus in an effort to determine the probable site of origin of tinnitus.

Among the patients who visited the outpatient clinic of the Department of Otolaryngology at our tertiary hospital from January 2016 to December 2019, adolescents aged 13-18 years with the chief complaint of unilateral subjective tinnitus and pure tone audiometry (PTA) within 25dB HL were enrolled and retrospectively reviewed. The ABR test parameters (amplitudes and latencies of waves I, III, and V and interpeak latencies [IPLs] of waves I-III, III-V, and I-V) were analyzed and compared between tinnitus ears and contralateral ears without tinnitus. Study participants were divided into the chronic tinnitus (tinnitus duration ≥6 months) and non-chronic tinnitus (tinnitus duration <6 months) groups, and the difference between the two groups was analyzed.

Ten adolescents were included in the study, and their ABR test results were reviewed. IPL III-V was significantly prolonged in tinnitus ears compared to non-tinnitus ears (p=0.035). Although other parameters were found to be statistically non-significant, there was preponderance in ABR wave I amplitude; it was smaller in tinnitus ears of chronic tinnitus adolescents than in those of non-chronic tinnitus adolescents (p=0.114).

The probable site of origin of tinnitus in adolescents with normal hearing might be in the upper brainstem of the auditory pathway. Further analysis of ABR test results in adolescents with tinnitus and normal hearing can help clarify the pathophysiology of tinnitus in adolescents.

To establish an optimized airway management process to improve preoperative lung dysfunction in obstructive sleep apnea (OSA).

The study included 483 children (319 males and 164 females; 6y to14yyears) with OSA who underwent an adenotonsillectomy from November 2017 to December 2018. Children with OSA and who had abnormal airway function were identified by lung function test, and the risk factors for abnormal lung function were assessed. Next, the children received individualized atomization intervention based on the severity of their abnormal lung function, and the improvement in lung function was evaluated.

Lung function tests revealed that 45 patients had obstructive ventilation dysfunction, and histories of chronic cough or asthma were identified as risk factors for perioperative abnormal lung function. The FEV1% pre exceeded 80% after 2 days of atomization intervention in 27 of 28 mild cases, 4 of 13 moderate cases, but in none of the 4 moderate-severe cases. After 4 days of atomization intervention, the FEV1%pre of the remaining 14 patients in the three groups all increased up to 80%. Other indicators of lung function (e.g., FEV1/FVC% pre, MEF50% pre, MEF25% pre, and MMEF% pre) were also greatly improved following the improvement of FEV1% pre. No perioperative airway complications occurred.

Prior to performing surgery on children with OSA and who have risk factors associated with abnormal lung function, it is potentially beneficial to establish an optimized airway management process to improve lung function before adenotonsillectomy.

Multiple studies have shown improved outcomes and higher utilization of care with the increase of insurance coverage. This study aims to assess whether Medicaid expansion (ME) has changed the utilization and outcomes of abdominal aortic aneurysm (AAA) repair in the United States.

Retrospective observational study.

Data of patients undergoing AAA repair in the Vascular Quality Initiative (2010-2017).

Interrupted time-series (ITS) analysis was utilized to evaluate changes in annual trends of postoperative outcomes after elective AAA repair before and after 2014. We also assessed if these trend changes were significant by comparing the changes in states which adopted ME in 2014 versus nonexpansion states (NME), and conducting a difference-in-difference analysis. Primary outcomes included in-hospital mortality and adverse events (bowel and leg ischemia, cardiac, renal, respiratory, stroke and return to the OR).

A total of 19,143 procedures were included (Endovascular 85.8% and open 14.2%), of which 40.9s a significant increase of elective AAA cases and EVAR utilization and a decrease in in-hospital complications in ME States.The US National Park Service (NPS) Night Skies Program measured changes in sky brightness resulting from a countywide lighting retrofit project. The retrofit took place in Chelan County, a gateway community to North Cascades National Park and Lake Chelan National Recreation Area in Washington State. The county retrofitted all 3693 county-owned high pressure sodium (HPS) street lamps to full cutoff LEDs. This number is about 60% of the County's total outdoor street and area lights. About 80% of the newly installed lights were 3000 K in color temperature and 20% were 4000 K. The 4000 K LEDs were used to meet Washington State Department of Transportation guidelines. To measure sky brightness, we used the NPS night sky camera system before the retrofit started in 2018 and after its completion in 2019. These images were photometrically calibrated and mosaicked together to provide hemispherical images in V band. For comparison with our ground-based measurement, we obtained the satellite imagery taken by Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi National Polar-orbiting Partnership satellite. Our measurements show that the post-retrofit skyglow became brighter and extended higher in the sky, but upward radiance, as measured by the day-night band radiometer, decreased. https://www.selleckchem.com/products/Perifosine.html These divergent results are likely explained by a substantial increase in light emitted at wavelengths shorter than 500 nm, and a relative decrease in upward light emission due to better shielded luminaires. These results also demonstrate that earlier models relating VIIRS day-night band data to skyglow will - at a minimum - require substantial revision to account for the different characteristics of solid state luminaires.According to data from the working reports of China's 244 prefecture-level city governments from 2004 to 2016, we used the instrumental variable method to identify the effects of governments' behavior of setting economic growth targets on regional green technology innovation. The results show that the setting and top-down amplification of economic growth targets have significant inhibitory effects on green technology innovation. The inhibitory effect is more prominent in cities with rapid economic growth and over fulfilment of economic growth targets. In addition, the higher the degree of over fulfilment of the economic target becomes, the more prominent the inhibiting effect is. An impact mechanism analysis reveals that economic growth target constraints affect regional green technology innovation through an industrial structure effect and foreign investment introduction effect.In the present study, a two-step bioaugmentation strategy (TSBS) was implemented by using indigenous bacterial consortium to enhance the degradation of total petroleum hydrocarbons (TPH) from petroleum refinery sludge (PRS). A bacterial consortium was developed using four indigenous isolated strains, Dietzia sp. IRB191, Dietzia sp. IRB192, Staphylococcus sp. BSM19 and Stenotrophomonas sp. IRB19 from PRS. The optimum conditions of pH, temperature, and sludge concentration were 7, 34 °C, and 2% (w/v), respectively, for maximum TPH degradation, obtained using one variable at a time approach. Under the optimal culture conditions, the developed consortium was inoculated twice to the culturing medium, at the beginning (0th day) and again on the 10th day for implementing a novel TSBS. The maximum TPH degradation of 91.5 ± 2.28% was found with TSBS, which was 1.18 times higher than that of SSBS (77.3 ± 2.6%) in 15 days of incubation. GC-FID study also confirmed that the TPH present in the PRS was effectively degraded by the bacterial consortium with TSBS.

Despite the social nature of most drinking experiences, prior work has largely failed to incorporate social context into the study of alcohol's effects on emotion. The present study provides an initial test of the effect of alcohol on mood among platonic friends drinking together in a non-stress setting. We hypothesized that subjects would report more positive postdrink mood after consuming alcohol than after consuming a nonalcoholic control beverage.

Dyads of platonic male friends (n=36; 55.55% White, 38.88% Asian, 5.55% Black) attended two laboratory-based experimental sessions, wherein their drink conditions (alcohol vs. no alcohol control) were randomized by dyad and counter-balanced across sessions. They reported their mood before and after consuming their beverages together, using the Positive and Negative Affect Schedule and an 8-item mood measure.

As hypothesized, alcohol enhanced positive mood (


β

=0.26, p<0.01). Although in the expected direction, the effect of alcohol on negative mood was not significant (


β

=-0.12, p=0.17). Post hoc analyses revealed that alcohol yielded greater increases in both stimulation (

This study highlights the positive mood-enhancing and broader subjective effects of alcohol when drinking with a platonic friend and encourages further consideration of friendship contexts in the examination of alcohol's effects when developing models of the etiology of alcohol use disorder.

As the sole species within the sister lineage to all other extant flowering plants, Amborella trichopoda is an important model for understanding the evolution and development of flowers. Plants typically produce only male or female flowers, but sex determination mechanisms are unknown for the species. Sequence data derived from plants of natural origin and an F1 mapping population were used to identify sex-linked genes and the nonrecombining region. https://www.selleckchem.com/products/Adrucil(Fluorouracil).html Amborella trichopoda has a ZW sex determination system. Analysis of genes in a 4 Mb nonrecombining sex-determination region reveals recent divergence of Z and W gametologs, and few Z- and W-specific genes. The sex chromosomes of A. trichopoda evolved less than 16.5 Myr ago, long after the divergence of the extant angiosperms.
The quality of a measured distribution of dose delivered against its corresponding radiotherapy plan is routinely assessed by gamma index (GI) and dose-volume histogram (DVH) metrics.

In formal terms, there cannot be any correlation between γ P and any common DVH-calculated patient-specific measures, with respect to PTV or OAR. However, as demonstrated analytically and further confirmed in our simulation studies, the γ P approximation derived in this study (the " γ -slope indicator") may in some cases offer a degree of correlation between γ P and the PTV and OAR DVH QA metrics in measured and planned patient-specific dose distributions-which may be potentially useful in clinical practice.
Because there is high variability among European countries in prevalence levels of various alcohol consumption measures, the informational value of adolescent's alcohol consumption indicators is uncertain. The present study aimed to examine information capacity and measurement invariance of different alcohol consumption indicators in adolescents from countries of the former Soviet (Eastern) Bloc in Central and Eastern Europe (CEE).

Data were collected in 16 CEE countries, as part of the 2013/2014 wave of the Health Behavior in School-aged Children study. Data from adolescents (age 15) who reported having consumed alcohol at least once in their lifetime were analyzed. Four binary items selected for analysis measured the presence or absence of alcohol consumption in the last 30days, lifetime drunkenness, weekly drinking frequency, and binge drinking on a typical occasion. Multiple group confirmatory factor analysis and item response theory analysis were used to examine the data.

In most of the included co at the lower and higher ends of the continuum of alcohol use severity.
The current study examined associations between Minnesota Multiphasic Personality Inventory-3 (MMPI-3) scales and self-reported DSM-5 Section II personality disorder (PD) symptoms. A priori hypotheses were generated for which MMPI-3 scales would be most highly associated with each PD.

We used a large sample (n = 489) of university students, who completed the MMPI-3 and two established self-report measures of personality disorders.

The results were generally consistent with theoretical expectations and previous research utilizing the MMPI-2-RF. Specifically, most hypothesized MMPI-3 scales exhibited meaningful associations with relevant PD variables, although there were some notable exceptions. The regression models revealed significant predictors for each PD which were generally consistent with expectations and previous research.

Overall, the MMPI-3 appears well situated to cover a range of DSM-5 Section II PD-related psychopathology, and three of the new MMPI-3 scales appear to have added utility for assessing personality pathology.

Consequently, sponsors of new molecular entities (NMEs) often conduct clinical studies with priority given to OCs as victims of cytochrome P450 (CYP) 3A (CYP3A) induction and inhibition. Such scenarios are reflected in the US Food and Drug Administration-issued guidance documentation related to OC DDI studies. Although CYP3A is important, OCs such as EE are metabolized by sulfotransferase 1E1 and UDP-glucuronosyltransferase (UGT) 1A1, expressed in the gut and liver, and so both can also serve as loci of victim OC DDI. Therefore, for any NME, one should carefully consider its induction and inhibition profile involving CYP3A4/5, UGT1A1, and SULT1E1. As DDI perpetrators, available clinical DDI data indicate that EE-containing OCs can induce (e.g., UGT1A4 and CYP2A6) and inhibit (CYP1A2 ≥ CYP2C19 > CYP3A4/5 > CYP2C8, CYP2B6, CYP2D6, and CYP2C9) various CYP forms. Although available in vitro CYP inhibition data do not explain such a graded inhibitory effect in vivo, it is hypothesized that EE differentially modulates CYP expression via potent agonism of the estrogen receptor expressed in the gut and liver. From the standpoint of the NME as potential OC DDI victim, therefore, it is important to assess its projected (pre-phase I) or known therapeutic index and pharmacokinetic profile (fraction absorbed, absolute oral bioavailability, clearance/extraction class, fraction metabolized by CYP1A2, CYP2C19, CYP2A6, and UGT1A4). Such information can enable the prioritization, design, and interpretation of NME-OC DDI studies.
The degree to which binge and high-intensity drinking prevalence estimates vary from fixed threshold frequency and continuous maximum drinks measures is unknown. The current study compared prevalence estimates for adolescent binge and high-intensity drinking (5+ drinks, 10+ drinks, respectively) and sex-specific thresholds using fixed threshold frequency and continuous maximum drinks measures.

Data were obtained from 7911 respondents participating in the 2018 and 2019 nationally representative Monitoring the Future 12th-grade surveys. Comparisons of frequency prevalence (e.g., any occasions of 5+ drinking using the frequency measure) versus maximum drinks prevalence (e.g., reporting 5 or more drinks using the maximum number of drinks measure) were made using all respondents and then separately within males and females.

Among the sample overall and within sex, binge drinking estimates from the 5+ frequency prevalence and 5+ maximum drinks prevalence measures evidenced overlapping confidence intervals (esBoth the frequency and maximum drinks measures provided comparable estimates of binge and high-intensity drinking prevalence among older adolescents.
In this nationally representative sample of 12th-grade students, prevalence levels for 5+ and 10+ drinking did not differ significantly when using frequency versus maximum drinks measures. Among females, binge drinking prevalence was higher using sex-specific versus universal thresholds. Both the frequency and maximum drinks measures provided comparable estimates of binge and high-intensity drinking prevalence among older adolescents.Neurodevelopmental neuropsychiatric disorders, such as autism spectrum disorder and schizophrenia, have strong genetic risk components, but the underlying mechanisms have proven difficult to decipher. Rare, high-risk variants may offer an opportunity to delineate the biological mechanisms responsible more clearly for more common idiopathic diseases. Indeed, different rare variants can cause the same behavioral phenotype, demonstrating genetic heterogeneity, while the same rare variant can cause different behavioral phenotypes, demonstrating variable expressivity. These observations suggest convergent underlying biological and neurological mechanisms; identification of these mechanisms may ultimately reveal new therapeutic targets. At the 2021 Keystone eSymposium "Neuropsychiatric and Neurodevelopmental Disorders Harnessing Rare Variants" a panel of experts in the field described significant progress in genomic discovery and human phenotyping and raised several consistent issues, including the need for detailed natural history studies of rare disorders, the challenges in cohort recruitment, and the importance of viewing phenotypes as quantitative traits that are impacted by rare variants.

Lifestyles habits such as eating unhealthy foodscommence at home and are associated with the development of obesity and comorbidities such as insulin resistance, metabolic syndrome, and chronic degenerative diseases, which are the main causes of death in adults. The present study compared changes in dietary habits, behaviors and metabolic profiles of obese children whose mothers attended at the hospital to group sessions, with those who received the usual nutritional consultation.

Randomized clinical trial, 177 mother/obese child pairs participated, 90 in the intervention group and 87 in the control group. The intervention group attended six group education sessions to promote healthy eating, being this an alternative of change of habits in children with obesity. The control group received the usual nutritional consultation; both groups were followed up for 3 months. https://www.selleckchem.com/products/ici-118551-ici-118-551.html Frequency of food consumption, behaviors during feeding in the house and metabolic profile was evaluated.

The objectives of this study were to investigate the HRQoL of residents living in central urban areas (CUA) and developing neighborhoods (DN) areas of North-China and to examine the relationship between health conditions and the physical and mental components of quality of life.

A stratified random sample was taken and health survey scoring system questionnaire SF-36 was used to conduct the HRQoL survey among community residents in the two selected districts in 10 cities. A general questionnaire was also administered with questions that collected general information, population demographic characteristics and health behaviours, social relationships and perception of life satisfaction.

Five thousand eight hundred eighty-one questionnaires were returned from 6059 invitations with a effective response rate of 97%. The residents in DN had a higher score of physical function, role limitation due to physical problems and vitality than those living in CUA. The prevalence of several chronic diseases was lower ieases are an important determinant on HRQoL. Several healthy habits and behaviors such as having a regular daily routine and exercising during leisure time improved HRQoL in Chinese urban communities. Targeted policies of public health based on these findings can better the health-related quality of life.
Globally, colorectal cancer (CRC) is the third and second leading cancer in men and women respectively with 600,000 deaths per year. Traditionally, clinicians have relied solely on nodal disease involvement, and measurements such as lymph node ratio (LNR; the ratio of metastatic/positive lymph nodes to total number of lymph nodes examined), when determining patient prognosis in CRC. The log odds of positive lymph nodes (LODDS) is a logistic transformation formula that uses pathologic lymph node data to stratify survival differences among patients within a single stage of disease. This formula allows clinicians to identify whether patients with clinically aggressive tumours fall into higher-risk groups regardless of nodal positivity and can potentially guide adjuvant treatment modalities. The aim of this study was to investigate whether LODDS in colon cancer provides better prognostication compared to LNR.

A retrospective study of patients on the prospectively maintained Cabrini Monash University Departmenor LNY < 12 and stage III patients when each were sub-grouped by LODDS and LNR.

This study has shown for that the prognostic impact of LODDS is comparable to LNR for colon cancer patients. Accordingly, LNR is recommended for prognostication given its ease of calculation.

Lung cancer is one of the most common carcinomas in the world, and lung adenocarcinoma (LUAD) is the most lethal and most common subtype of lung cancer. Cigarette smoking is the most leading risk factor of lung cancer, but it is still unclear how normal lung cells become cancerous in cigarette smokers. This study aims to identify potential smoking-related biomarkers associated with the progression and prognosis of LUAD, as well as their regulation mechanism using an in vitro carcinogenesis model and bioinformatics analysis.

Based on the integration analysis of four Gene Expression Omnibus (GEO) datasets and our mRNA sequencing analysis, 2 up-regulated and 11 down-regulated genes were identified in both S30 cells and LUAD. By analyzing the LUAD dataset in The Cancer Gene Analysis (TCGA) database, 3 of the 13 genes, viz., glycophorin C (GYPC), NME/NM23 nucleoside diphosphate kinase 1 (NME1) and slit guidance ligand 2 (SLIT2), were found to be significantly correlated with LUAD patients' smoking history. Theions indicated that the differential expression of GYPC, NME1 and SLIT2 may be regulated by DNA methylation, and they are associated with cigarette smoke-induced LUAD, as well as serve as prognostic factors in LUAD patients.
The Icelandic Prevention Model (IPM) is a collaborative upstream model that was designed to influence risk and protective factors related to substance use within the community, school, peer and family contexts. By engaging whole communities, the IPM has been found to be effective in reducing youth substance use behaviours across Iceland. As an extension to the IPM's participatory approach, this research will examine how youth involvement can enhance outcomes. In addition, this research will evaluate whether the IPM approach is beneficial for mental health promotion and general youth wellbeing.

The present research protocol applies the bioecological model within a participatory mixed-method case study design to examine the implementation of the IPM in a rural community in Canada. This study was designed to identify whether the Icelandic substance use prevention model is effective in reducing substance use and promoting mental health and development for Canadian youth. It will also explore how to engage youth within the approach and how this adaptation influences implementation and outcomes.
