The longer the duration of school closure and reduction of daily physical activity, the higher was the predicted increase of Body Mass Index and childhood obesity prevalence. There is a need to identify children and adolescents at higher risk of learning and mental health impairments and support them during school closures.PM2.5 not only harms physical health but also has negative impacts on the public's wellbeing and cognitive and behavioral patterns. However, traditional air quality assessments may fail to provide comprehensive, real-time monitoring of air quality because of the sparse distribution of air quality monitoring stations. Overcoming some key limitations of traditional surface monitoring data, Web-based social media platforms, such as Twitter, Weibo, and Facebook, provide a promising tool and novel perspective for environmental monitoring, prediction, and evaluation. This study aims to investigate the relationship between PM2.5 levels and people's emotional intensity by observing social media postings. This study defines the "emotional intensity" indicator, which is measured by the number of negative posts on Weibo, based on Weibo data related to haze from 2016 and 2017. This study estimates sentiment polarity using a recurrent neural networks model based on LSTM (Long Short-Term Memory) and verifies the correlation between high PM2.5 levels and negative posts on Weibo using a Pearson correlation coefficient and multiple linear regression model. This study makes the following observations (1) Taking the two-year data as an example, this study recorded the significant influence of PM2.5 levels on netizens' posting behavior. (2) Air quality, meteorological factors, the seasons, and other factors have a strong influence on netizens' emotional intensity. (3) From a quantitative viewpoint, the level of PM2.5 varies by 1 unit, and the number of negative Weibo posts fluctuates by 1.0168 units. Thus, it can be concluded that netizens' emotional intensity is significantly positively affected by levels of PM2.5. The high correlation between PM2.5 levels and emotional intensity and the sensitivity of social media data shows that social media data can be used to provide a new perspective on the assessment of air quality.Enteric infections are a major cause of neonatal death in South American camelids (SACs). The aim of this study was to determine the prevalence of enteric viral pathogens among alpacas and llamas in Canchis, Cuzco, located in the southern Peruvian highland. Fecal samples were obtained from 80 neonatal alpacas and llamas and tested for coronavirus (CoV), mammalian orthoreovirus (MRV), and rotavirus A (RVA) by RT-PCR. Of the 80 fecal samples analyzed, 76 (95%) were positive for at least one of the viruses tested. Overall, the frequencies of positive samples were 94.1% and 100% among alpacas and llamas, respectively. Of the positive samples, 33 (43.4%) were monoinfected, while 43 (56.6%) had coinfections with two (83.7%) or three (16.3%) viruses. CoV was the most commonly detected virus (87.5%) followed by MRV (50%). RVA was detected only in coinfections. To our knowledge, this is the first description of MRV circulation in SACs or camelids anywhere. These data show that multiple viruses circulate widely among young alpaca and llama crias within the studied areas. These infections can potentially reduce livestock productivity, which translates into serious economic losses for rural communities, directly impacting their livelihoods.Plasma nitriding of titanium alloys is capable of effective surface hardening at temperatures significantly lower than gas nitriding, but at a cost of much stronger surface roughening. Especially interesting are treatments performed at the lower end of the temperature window used in such cases, as they are least damaging to highly polished parts. Therefore identifying the most characteristic defects is of high importance. The present work was aimed at identifying the nature of pin-point bumps formed at the glow discharged plasma nitrided Ti-6Al-7Nb alloy using plan-view scanning and cross-section transmission electron microscopy methods. It helped to establish that these main surface defects developed at the treated surface are (Ti,Al)O2 nano-whiskers of diameter from 20 nm to 40 nm, and length up to several hundreds of nanometers. The performed investigation confirmed that the surface imperfection introduced by plasma nitriding at the specified range should be of minor consequences to the mechanical properties of the treated material.Gyroscopes merit an undeniable role in inertial navigation systems, geodesy and seismology. By employing the optical Sagnac effect, ring laser gyroscopes provide exceptionally accurate measurements of even ultraslow angular velocity with a resolution up to 10-11 rad/s. With the recent advancement of ultrafast fibre lasers and, particularly, enabling effective bidirectional generation, their applications have been expanded to the areas of dual-comb spectroscopy and gyroscopy. https://www.selleckchem.com/products/cynarin.html Exceptional compactness, maintenance-free operation and rather low cost make ultrafast fibre lasers attractive for sensing applications. Remarkably, laser gyroscope operation in the ultrashort pulse generation regime presents a promising approach for eliminating sensing limitations caused by the synchronisation of counter-propagating channels, the most critical of which is frequency lock-in. In this work, we overview the fundamentals of gyroscopic sensing and ultrafast fibre lasers to bridge the gap between tools development and their real-world applications. This article provides a historical outline, highlights the most recent advancements and discusses perspectives for the expanding field of ultrafast fibre laser gyroscopes. We acknowledge the bottlenecks and deficiencies of the presented ultrafast laser gyroscope concepts due to intrinsic physical effects or currently available measurement methodology. Finally, the current work outlines solutions for further ultrafast laser technology development to translate to future commercial gyroscopes.In this investigation, for the first time, we used Fragaria ananassa (strawberry) leaf extract as a source of natural reducing, capping or stabilizing agents to develop an eco-friendly, cost-effective and safe process for the biosynthesis of metal-based nanoparticles including silver, copper, iron, zinc and magnesium oxide. Calcinated and non-calcinated zinc oxide nanoparticles also synthesized during a method different from our previous study. To confirm the successful formation of nanoparticles, different characterization techniques applied. UV-Vis spectroscopy, X-ray Diffraction (XRD) spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) coupled with Energy Dispersive X-ray Spectroscopy (EDS), Photon Cross-Correlation Spectroscopy (PCCS) and Fourier Transformed Infrared Spectroscopy (FT-IR) were used to study the unique structure and properties of biosynthesized nanoparticles. The results show the successful formation of metal-based particles in the range of nanometer, confirmed by different characterization techniques.

Why Invest in a Van Door Lock?

If your vehicle is targeted by thieves, the loss can be devastating for your business. Restocking equipment and tools and equipment, avoiding jobs, and dealing with insurance claims can impact your bottom line.

https://notes.io/w4r64 can find valuable information and reviews about van security door locks through reading user-generated content.

Deadlocks

Van deadlocks can be an excellent option for any vehicle in need of additional security. They work in conjunction with the locks that came with your vehicle to increase the level security and make it difficult for thieves access your equipment or valuables. These locks are particularly beneficial for those who travel with expensive possessions or work in areas where crime is high.

Although some locks are made to be DIY however, it's recommended to hire a professional to ensure that they're fitted correctly and provide the highest level of security. In addition some locks require regular maintenance and upkeep to keep their effectiveness. This includes lubricating and examining the lock for signs of wear and damage. Inability to do this can result in the lock failing which could lead to break-ins and thefts of your goods or tools.

There are many different types of van security locks, each with their own distinct advantages. Some are designed to guard against theft, while some are more focused on the physical security of the door and its contents. Some are designed to resist lock picking, drilling or other tampering techniques. Some are designed to be visible to deter thieves.

Installing a van lock is a good investment for any company that uses a vehicle as a means to transport valuable items. A successful theft can cause a negative impact on a business, not only since it can affect the value of the items but also the financial viability. To avoid costly theft, you should consider installing van security locks for doors and other security measures, like GPS trackers and alarms. This will keep your tools and goods secure and safe which will allow you to continue operating your business without interruption.

Hook locks

Vans are frequently targeted by thieves because they are usually full of valuable cargo like tools, equipment and merchandise. However, a good van door security lock can aid in protecting your belongings and stop criminals from gaining access to your vehicle. This lock also helps reduce the amount of money you'll lose if your possessions are stolen.

Hook locks are one of the most popular van security upgrades available and can be installed to rear doors, side doors barn doors, tailgates, or doors to the cab on various manufacturers. They are designed to fit inside the gap around your existing lock and use the strength of a hook-shaped bolt that extends into a receiver keep on the bodywork. This gives you a superior level of protection against "Peel and steal" crimes, door bending and door spreading. They operate independently of the locking system used by the manufacturer and can be locked or unlocked with high-security keys.



Hook locks are stronger than deadlocks due to being bolted to the door frame. They also come with a lock shield that prevents forced opening. The lock shield is an extremely heavy metal plate that is positioned between the frame of the door and the lock to make it harder for criminals to to open the lock. This is especially helpful when you're an owner-driver who relies on the lock to operate.

A hook lock can be affixed to the roof or floor to provide an additional layer of security. If your van is taken the hook lock will prevent it from being driven and assist the police in recovering the items taken. It can be used to secure a panel van's cargo area so that it doesn't move while in transit.

Catalytic converter locks

There are many van security locks that are available, all of which offer different levels of security. Some are more suitable for some situations than others, so it is essential to choose one that is appropriate for your needs. A van deadlock, for example is a good choice for those who are able to park their vehicles overnight or carry expensive tools. A lock with a slam is better for delivery drivers who lock and unlock their vehicles often throughout the day.

A catalytic converter locking device is another option that can be beneficial. It stops thieves from removing your vehicle's exhaust system. This can be a costly loss to repair, so it is worth investing in one of these locks to prevent this from occurring. These locks can be fitted around the catalytic filter, and come with window decals that warn thieves of the protection provided.

Lock shields can be beneficial to the security of a van as they protect it from threats which could cause a break-in. They are constructed by enclosing the lock with a robust steel plate, making it more difficult for thieves to force or pry a lock open. The locks are typically designed for every van model, and can be installed by a professional.

A loom guard is a different way to improve your van's security as it stops thieves from cutting the door cables. This method of gaining access to the vehicle is often used by thieves who are looking for valuable items. By stopping the removal of these cables, you are able to keep your tools and valuables safe in your vehicle. A lot of these devices are keyed alike, which means they can be used with the original van locks. This will give you more security and comfort.

Locks XL

A van that you use for work comes with certain risks, particularly if you store valuables and expensive equipment inside. However, there are many ways to protect your vehicle and prevent thieves from pursuing it. Installing van locks made of top quality, external shields and braces with anti-peel are among the best methods to protect your vehicle. These security measures could also lower your insurance costs.

A XL lock is a fantastic option for commercial vehicles as it is made of steel that has been hardened and zinc bodies to avoid corrosion. It can be affixed to any door and is suitable for all types of vans. It has also been tested to 200,000 operation cycles and is rust-proof for 24 hours. It is also simple to use, and does not require drilling to be done.

XL locks feature an inner frame that works as a receiver hasp to a cylinder lock, and it comes in various lock configurations to fit the majority of vehicles. The hooks are integrated into the frame, and it is fitted with two bolts on the interior of the vehicle to help keep it from being removed or lifted. The cylinder lock has been placed above the strikeplate and hasp to protect it from pick attacks.

These van locks are designed to be as strong as possible, and they can withstand the most common attempted break-ins. In fact, a few of them are certified by Thatcham to guard against direct hammer and slamming strikes. They are a great option for delivery drivers as well as couriers as they prevent thieves from targeting other vehicles.

Other security enhancements include a van slam lock, which can be activated by pressing the button on your keychain. This kind lock is perfect for couriers and delivery drivers who often forget to manually lock their vehicle. It also works as a visual deterrent criminals, as it is visible from the outside of the vehicle.

The role of bone tissue engineering is to regenerate tissue using biomaterials and stem cell-based approaches. Combination of two or more cell types is one of the strategies to promote bone formation. https://www.selleckchem.com/ALK.html Endothelial progenitor cells (EPCs) may enhance the osteogenic properties of mesenchymal stem cells (MSCs) and promote bone healing; this study aimed to investigate the possible mechanisms of EPCs on promoting osteogenic differentiation of MSCs.

MSCs and EPCs were isolated and co-cultured in Transwell chambers, the effects of EPCs on the regulation of MSC biological properties were investigated. Real-time PCR array, and western blotting were performed to explore possible signaling pathways involved in osteogenesis. The expression of osteogenesis markers and calcium nodule formation was quantified by qRT-PCR, western blotting, and Alizarin Red staining.

Results showed that MSCs exhibited greater alkaline phosphatase (ALP) activity and increased calcium mineral deposition significantly when co-cultured with EPCs. The mitogen-activated protein kinase (MAPK) signaling pathway was involved in this process. p38 gene expression and p38 protein phosphorylation levels showed significant upregulation in co-cultured MSCs. Silencing expression of p38 in co-cultured MSCs reduced osteogenic gene expression, protein synthesis, ALP activity, and calcium nodule formation.

These data suggest paracrine signaling from EPCs influences the biological function and promotes MSCs osteogenic differentiation. Activation of the p38MAPK pathway may be the key to enhancing MSCs osteogenic differentiation via indirect interactions with EPCs.

Epidemiological studies suggest that singletons born from assisted reproductive technologies (ART) have a high risk of adverse perinatal outcomes, specifically for imprinting disorders. Because ART processes take place at times when epigenetic reprogramming/imprinting are occurring, there is concern that ART can affect genomic imprints. However, little is currently known about the risk of imprinting defects according to the type of ART or the type of underlying female infertility. From the French national health database, a cohort of 3,501,495 singletons born over a 5-year period (2013-2017) following fresh embryo or frozen embryo transfers (fresh-ET or FET from in vitro fertilization), intrauterine insemination, or natural conception was followed up to early childhood. Based on clinical features, several syndromes/diseases involving imprinted genes were monitored. The effects of ART conception and the underlying cause of female infertility were assessed.

Compared with infants conceived naturally, childreges. Further studies are now needed to improve understanding of the underlying molecular mechanisms (i.e. genetic or epigenetic causes).
This prospective epidemiological study showed that the risk of clinically diagnosed imprinting-related diseases is increased in children conceived after fresh embryo transfers or from mothers with endometriosis. The increased perturbations in genomic imprinting could be caused by controlled ovarian hyperstimulation and potentially endometriosis through the impairment of endometrial receptivity and placentation, leading to epigenetic feto-placental changes. Further studies are now needed to improve understanding of the underlying molecular mechanisms (i.e. genetic or epigenetic causes).
Overexpression of c-Myc is required for the progression of pre-malignant plasma cells in monoclonal gammopathy of undetermined significance (MGUS) to malignant plasma cells in multiple myeloma (MM). c-Myc also increases glutamine anaplerosis into the tricarboxylic acid (TCA) cycle within cancer cells. Whether increased glutamine anaplerosis is associated with the progression of pre-malignant to malignant plasma cells is unknown.

Human volunteers (N= 7) and patients with MGUS (N= 11) and MM (N= 12) were prospectively recruited to undergo an intravenous infusion of
C-labeled glutamine followed by a bone marrow aspiration to obtain bone marrow cells and plasma.

Despite notable heterogeneity, stable isotope-resolved metabolomics (SIRM) revealed that the mean
C-labeled glutamine anaplerosis into the TCA cycle was higher in malignant compared to pre-malignant bone marrow plasma cells relative to the remainder of their paired bone marrow mononuclear cells. RNA sequencing demonstrated a higher relative mRNA expression of c-Myc and glutamine transporters such as ASCT2 and SN2 in malignant compared to pre-malignant bone marrow plasma cells. Finally, higher quantitative levels of TCA cycle intermediates in the bone marrow plasma differentiated MM from MGUS patients.

Measurement of the in vivo activity of glutamine anaplerosis into the TCA cycle provides novel insight into the metabolic changes associated with the transformation of pre-malignant plasma cells in MGUS to malignant plasma cells in MM.

These results indicate that PGC-1α has a protective role in oxidative stress-induced-hepatocyte EMT and liver fibrosis.An amendment to this paper has been published and can be accessed via a link at the top of the paper.The conceptual understanding of charge transport in conducting polymers is still ambiguous due to a wide range of paracrystallinity (disorder). Here, we advance this understanding by presenting the relationship between transport, electronic density of states and scattering parameter in conducting polymers. We show that the tail of the density of states possesses a Gaussian form confirmed by two-dimensional tight-binding model supported by Density Functional Theory and Molecular Dynamics simulations. Furthermore, by using the Boltzmann Transport Equation, we find that transport can be understood by the scattering parameter and the effective density of states. Our model aligns well with the experimental transport properties of a variety of conducting polymers; the scattering parameter affects electrical conductivity, carrier mobility, and Seebeck coefficient, while the effective density of states only affects the electrical conductivity. We hope our results advance the fundamental understanding of charge transport in conducting polymers to further enhance their performance in electronic applications.A complex interplay of metabolic and immunological mechanisms underlies many diseases that represent a substantial unmet medical need. There is an increasing appreciation of the role microbes play in human health and disease, and evidence is accumulating that a new class of live biotherapeutics comprised of engineered microbes could address specific mechanisms of disease. Using the tools of synthetic biology, nonpathogenic bacteria can be designed to sense and respond to environmental signals in order to consume harmful compounds and deliver therapeutic effectors. In this perspective, we describe considerations for the design and development of engineered live biotherapeutics to achieve regulatory and patient acceptance.Several strands of evidence question the dogma that human mitochondrial DNA (mtDNA) is inherited exclusively down the maternal line, most recently in three families where several individuals harbored a 'heteroplasmic haplotype' consistent with biparental transmission. Here we report a similar genetic signature in 7 of 11,035 trios, with allelic fractions of 5-25%, implying biparental inheritance of mtDNA in 0.06% of offspring. However, analysing the nuclear whole genome sequence, we observe likely large rare or unique nuclear-mitochondrial DNA segments (mega-NUMTs) transmitted from the father in all 7 families. Independently detecting mega-NUMTs in 0.13% of fathers, we see autosomal transmission of the haplotype. Finally, we show the haplotype allele fraction can be explained by complex concatenated mtDNA-derived sequences rearranged within the nuclear genome. We conclude that rare cryptic mega-NUMTs can resemble paternally mtDNA heteroplasmy, but find no evidence of paternal transmission of mtDNA in humans.Avoiding and removing surface contamination is a crucial task when handling specimens in any scientific experiment. This is especially true for two-dimensional materials such as graphene, which are extraordinarily affected by contamination due to their large surface area. While many efforts have been made to reduce and remove contamination from such surfaces, the issue is far from resolved. https://www.selleckchem.com/products/ipi-549.html Here we report on an in situ mechanical cleaning method that enables the site-specific removal of contamination from both sides of two dimensional membranes down to atomic-scale cleanliness. Further, mechanisms of re-contamination are discussed, finding surface-diffusion to be the major factor for contamination in electron microscopy. Finally the targeted, electron-beam assisted synthesis of a nanocrystalline graphene layer by supplying a precursor molecule to cleaned areas is demonstrated.Metastasis is one of the most common reasons of hepatocellular carcinoma (HCC) death; however, the molecular mechanism underlying HCC metastasis remains incompletely defined. Here we report a new function of Zinc Finger Protein 703 (ZNF703), a member of the NET/NlZ family of zinc finger transcription factors, in promoting hepatocellular carcinoma metastasis. We demonstrated that the overexpression of ZNF703 in human HCC tissue is correlated with tumor metastasis and recurrence, it is also related with the prognosis and survival rate of patients. ZNF703 overexpression promotes HCC progression in vitro and in vivo, whereas ZNF703 knockdown has the opposite effect. In addition, ZNF703 induces epithelialmesenchymal transition (EMT) via directly binding to the CLDN4 promoter and transactivating CLDN4 expression. Downregulation of CLDN4 can attenuate ZNF703-mediated HCC metastasis, whereas upregulation of CLDN4 can reverse the decreased metastasis induced by ZNF703 knockdown. Our data revealed that ZNF703 expression is correlated with CLDN4 level, the overexpression of both ZNF703 and CLDN4 are leaded to poorer prognosis of patients with HCC. Moreover, ZNF703 knockdown can enhance the sensitivity of HCC cell to sorafenib, whereas ZNF703 overexpression has the opposite effect. These results suggested that ZNF703 might be a potential target for cancer therapies and a candidate prognostic biomarker for predicting whether patients with HCC are befitting for sorafenib treatment.The long noncoding RNA (lncRNA), HOX antisense intergenic RNA myeloid 1 (HOTAIRM1), has been shown to act as a tumor suppressor in various human cancers. However, the overall biological roles and clinical significance of HOTAIRM1 in papillary thyroid cancer (PTC) have not been investigated. In this study, we used quantitative reverse transcription PCR (qRT-PCR) to show that HOTAIRM1 was significantly downregulated in PTC tissues and low HOTAIRM1 expression levels were associated with lymph node metastasis and advanced TNM stage. We performed Cell Counting Kit-8, plate colony-formation, flow cytometric apoptosis, transwell, and scratch wound healing assays. Overexpression of HOTAIRM1 was found to inhibit PTC cell proliferation, invasion, and migration in vitro. Additionally, we identified miR-107 as a target of HOTAIRM1 using online bioinformatics tools. Dual-luciferase reporter gene and RNA immunoprecipitation assays were used to confirm that HOTAIRM1 acted as a competing endogenous RNA of miR-107. Furthermore, enhancement of miR-107 could potentially reverse the effects of HOTAIRM1 overexpression in vitro.

In contrast, LATS2 can promote the production of TAG and unsaturated fatty acids. "Rescue" experiments further verified the miR-497/LATS2 regulatory network. Overall, data underscored that the miR-497/LATS2 pathway exerts control on milk fat metabolism and provides a theoretical approach for improving milk quality via genetic means.The glass transition behaviors of thin polymer films on the sidewalls of carbon nanotubes (CNTs) in CNT sponges (CNTSs) were studied. Due to the extremely large surface area of CNTS, the glass transition temperatures (Tg) of thin polystyrene (PS) and poly(methyl methacrylate) (PMMA) films were measured using a routine experimental method, differential scanning calorimetry (DSC). We thus provide a direct Tg comparison between the thin film and the bulk sample using the same DSC technique. For thin polymer films on the CNT sidewalls, free surface and polymer-substrate interfacial interactions co-exist. It is well-known that polymer chains at the liquid-like free surface tend to have a relatively high mobility, but the mobility in the interfacial layer near the substrate depends strongly on the polymer-substrate interaction strength. Accordingly, we tuned the polymer-substrate interaction strength by introducing an amphiphilic sodiumdodecylsulfate (SDS) molecule layer on the CNT sidewalls. The value and sign of Tg deviation were influenced by the competition between the free surface effect and the interfacial interactions. Strong polymer-substrate interactions led to a decrease in the mobility of polymer chains near the substrate and weak polymer-substrate interactions have little influence on the mobility of polymer chains near the substrate. When the polymer-substrate interactions are strong, both the free surface effect and the polymer-substrate interaction are key factors influencing the glass transition temperature. For thin polymer films having weak interactions with substrates, the free surface effect dominates the glass transition behavior and Tgs shows a large reduction. We also observed a double Tg behavior in the thin PS film and found the thickness of the PS film on the substrate was a deciding factor for controlling the spatial variation of Tg.Inorganic infrared (IR) second-order nonlinear optical (NLO) crystals have become increasingly important for fulfilling the demands of modern laser technology through frequency conversion via optical parametric oscillation (OPO) and optical parameter amplification (OPA) technology. The AI2BIICIVDVI4 family contains a large number of compounds (to our best knowledge, 102 formula) and shows abundant structural diversity; it could be regarded as a potential source of IR second-order NLO materials with tunable structures and properties. This article summarizes the authors' contributions to the AI2BIICIVDVI4 family, together with other reported related results where the NLO properties have been provided (a total of 38 compounds). https://www.selleckchem.com/products/as1842856.html In the title family (1) the AI site can be occupied by the univalent coinage metals Cu and Ag or the alkali metals Li and Na; (2) the BII site involves divalent metals, including the alkaline earth metals (AEM) Sr and Ba or the d10 metals Zn, Cd, and Hg; (3) the CIV site is prevalently IVA group semi-conducting Si and Ge, or Sn; and (4) the DVI site is S or Se. The structures and optical properties of these compounds are summarized and the influence of substitution at each site on the structures and properties is systematically analyzed.Herein, an anionic metal-organic framework, formulated as [Zn3(OH)(bmipia)(H2O)3]4·[Zn(H2O)6.5]2n (FCS-3), was prepared from zinc ions and semi-rigid carboxylate ligands of 5-[N,N-bis(5-methylisophthalic acid)amion] isophthalic acid (H6bmipia) and was employed as a unique fluorescence turn-on chemical sensor for the ultra-sensitive detection of various antibiotics in the aqueous phase.Self-derivation-behaviour of substrates is utilized to fabricate monolithic electrodes for oxygen evolution, in which the selected substrate functions as both the precursor of the active catalyst and a conductive support. In particular, NiFe layered double hydroxide (LDH) can be directly derived from the surface metal of commercial NiFe foam (NFF). Moreover, the as-prepared monolithic electrode exhibits enhanced activity and durability, originating from the resultant defective nanosheet structure and autologous catalyst-support features.The 7-azaindole building block has attracted considerable interest in the field of drug discovery in the current portfolio. Because of their powerful medicinal properties, the development of synthetic, elegant techniques for the functionalization of 7-azaindoles continues to be an active area of research. Advances in metal-catalyzed chemistry have recently supported the successful development of a number of novel and effective methods for functionalization of the 7-azaindole template. This review reports state-of-the-art functionalization chemistry of 7-azaindoles with an aspiration to highlight the global ring functionalization of 7-azaindoles that are potential as pharmacophores for various therapeutic targets. Other relevant reviews focused on 7-azaindole synthesis, properties and applications have also been reported. However, none of these reviews have been dedicated to the results achieved in the field of metal-catalyzed cross-coupling/C-H bond functionalized reactions. So we wish to discuss and summarize the advances made since 2011 in this field toward 7-azaindole functionalization.In this work, acid and matrix-tolerant multifunctionalized gold nanoparticles (AuNPs) with an integrated chiral selector towards tyrosine (Tyr) and polyethylenglycol (PEG) chains were developed for visual chiral discrimination of Tyr in biological samples under acid conditions. In brief, AuNPs multifunctionalized with N-acetyl-l-cysteine (NALC) and PEG (PEG/NALC-AuNPs) were prepared via a simple strategy. In the presence of l-Tyr, the color of PEG/NALC-AuNP solution changed from red to gray, while no obvious color change was observed with the introduction of d-Tyr, which indicated that the introduction of PEG onto the surface of AuNPs has no effect on the chiral recognition between l-Tyr and NALC. A computer-aided molecular model was used to clarify the chiral recognition mechanism between NALC and Tyr enantiomers and to further guide the optimization of sensitivity. The resultant PEG/NALC-AuNP sensor presented a significantly improved stability under acid and alkali conditions compared with conventional NALC-AuNPs, resulting in a wider dynamic range (500 nM-100 μM) and a 50 times reduced detection limit by simply adjusting the pH of the sensor system under acid conditions (pH 2-2.
