To evaluate the outcome of gonioscopy-assisted transluminal trabeculotomy (GATT) in patients with open-angle glaucoma (OAG).

A retrospective case series of patients with uncontrolled OAG treated by GATT at the cantonal Hospital Lucerne, a tertiary referral center, between October 2018 and July 2019 with a minimal 6-month follow-up period. Main outcome measures were intraocular pressure (IOP), number of antiglaucoma medications, and complications.

Thirty-one eyes of 29 patients with a mean age of 70.9 years and a minimal follow-up period of 6 months were included in this study. Twenty eyes were treated for pseudoexfoliation (64.5%), seven for primary open-angle (22.6%), three for pigmentary (9.7%), and one for traumatic (3.2%) glaucoma. https://www.selleckchem.com/products/Cediranib.html Twenty-six eyes had data at the 6-month follow-up and 12 eyes at the 12-month follow-up. Twenty-two eyes (70.9%) were pseudophakic prior to the operation. Mean preoperative IOP was 33 mmHg (standard deviation [SD] 8.0 mmHg). The postoperative IOP was 13.9 mmHg [SD 2.2] atnditions are encountered.
GATT is an effective and safe intervention for OAG, particularly in pseudoexfoliation glaucoma (PEX). The advantages of GATT compared to filtration surgery are the low rate of long-term complications and that the intervention is feasible even when difficult conjunctival conditions are encountered.
There are a variety of protocols for manufacturing autologous serum (AS) eye drops. The Lucerne protocol for the production of AS eye drops uses a slightly reduced gravitational (g)-force and time for the centrifugation process (2500 × g for 10 minutes), compared to previously published optimised protocols, to obtain high levels of epitheliotropic growth factors (3000 × g for 15 minutes). The goal of this study was to compare the concentrations of growth factors, albumin and lysozyme in autologous serum eye drops manufactured with these protocols.

Blood from 5 healthy volunteers was placed in plastic tubes without an anticoagulant. Tubes from each donor were left in a vertical position for 2 hours at room temperature to facilitate coagulation, followed by centrifugation at either 2500 × g for 10 minutes or at 3000 × g for 15minutes at room temperature. The serum levels of beta nerve growth factor (β-NGF), transforming growth factor β1 (TGF-β1), epidermal growth factor (EGF), hepatocyte growth factor (HGF)ic growth factors, albumin and lysozyme, in AS eye drops.
 In elderly patients with venous thromboembolism (VTE), the decision to extend anticoagulation beyond 3 months must be weighed against the bleeding risk. We compared the predictive performance of 10 clinical bleeding scores (VTE-BLEED, Seiler, Kuijer, Kearon, RIETE, ACCP, OBRI, HEMORR
HAGES, HAS-BLED, ATRIA) in elderly patients receiving extended anticoagulation for VTE.

 In a multicenter Swiss cohort study, we analyzed 743 patients aged ≥65 years who received extended treatment with vitamin K antagonists after VTE. The outcomes were the time to a first major and clinically relevant bleeding. For each score, we classified patients into two bleeding risk categories (low/moderate vs. high). We calculated likelihood ratios and the area under the receiver operating characteristic (ROC) curve for each score.

 Over a median anticoagulation duration of 10.1 months, 45 patients (6.1%) had a first major and 127 (17.1%) a clinically relevant bleeding. The positive likelihood ratios for predicting major bleeding ranged from 0.69 (OBRI) to 2.56 (Seiler) and from 1.07 (ACCP) to 2.36 (Seiler) for clinically relevant bleeding. The areas under the ROC curves were poor to fair and varied between 0.47 (OBRI) and 0.70 (Seiler) for major and between 0.52 (OBRI) and 0.67 (HEMORR
HAGES) for clinically relevant bleeding.

 The predictive performance of most clinical bleeding risk scores does not appear to be sufficiently high to identify elderly patients with VTE who are at high risk of bleeding and who may therefore not be suitable candidates for extended anticoagulation.

 Coronavirus disease 2019 (COVID-19) is a new disease; its clinical profile and natural history are evolving. Each well-recorded case in homeopathic practice is important for deciding the future course of action. This study aims at identifying clinically useful homeopathic remedies and their prescribing symptoms using the prognostic factor research model.

 This was an open-label, multi-centric, observational study performed from April 2020 to July 2020 at various public health care clinics. The data were collected prospectively from clinical practice at integrated COVID-19 care facilities in India. Good-quality cases were selected using a specific set of criteria. These cases were analyzed for elucidating prognostic factors by calculating the likelihood ratio (LR) of each frequently occurring symptom. The symptoms with high LR values (>1) were considered as prescribing indications of the specific remedy.

 Out of 327 COVID-19 cases reported, 211 met the selection criteria for analysis. The most common complaints were fatigue, sore throat, dry cough, myalgia, fever, dry mouth and throat, increased thirst, headache, decreased appetite, anxiety, and altered taste. Twenty-seven remedies were prescribed and four of them-
, and
-were the most frequently used. A high LR was obtained for certain symptoms, which enabled differentiation between the remedies for a given patient.

 Homeopathic medicines were associated with improvement in symptoms of COVID-19 cases. Characteristic symptoms of four frequently indicated remedies have been identified using prognostic factor research, findings that can contribute to accurate homeopathic prescribing during future controlled research in COVID-19.

In patients with atrial fibrillation, incomplete adherence to anticoagulants increases risk of stroke. Non-warfarin oral anticoagulants (NOACs) are expensive; we evaluated whether higher copayments are associated with lower NOAC adherence.

Using a national claims database of commercially-insured patients, we performed a cohort study of patients with atrial fibrillation who newly initiated a NOAC from 2012 to 2018. Patients were stratified into low (<$35), medium ($35-$59), or high (≥$60) copayments and propensity-score weighted based on demographics, insurance characteristics, comorbidities, prior health care utilization, calendar year, and the NOAC received. Follow-up was 1 year, with censoring for switching to a different anticoagulant, undergoing an ablation procedure, disenrolling from the insurance plan, or death. The primary outcome was adherence, measured by proportion of days covered (PDC). Secondary outcomes included NOAC discontinuation (no refill for 30 days after the end of NOAC supply) andercial insurance were associated with lower adherence and higher rates of discontinuation in the first year. Policies to lower or limit cost-sharing of important medications may lead to improved adherence and better outcomes among patients receiving NOACs.

However, the mechanisms have not been understood yet. https://www.selleckchem.com/products/mrtx1133.html Based on the depth-averaged model developed in the first-part of the series paper for planer shock ED system, this work focuses on the mechanisms of selective ion removal. We first assume plug feed flow and do scaling analysis, and identify three possible mechanisms of selective removal of multivalent cations smaller concentration left behind deionization zone, affinity to the charged surface where non-slip boundary slows down the velocity, and stronger push-back by streaming potential. Then we use numerical simulations to prove our hypothesis and show additional contribution from electroosmotic flow. Simulation results show that Mg is more removed from Na-Mg-Cl mixture at overlimiting current, which is qualitatively consistent with experiment results in literature.Adequate protein intake by very-low-birth-weight preterm infants (≤1,500 g at birth) is essential to optimize growth and development. The estimated needs for this population are the highest of all humans, however, the recommended intake has varied greatly over the past several years. A literature search was conducted in PubMed, Embase, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Cochrane Central databases to identify randomized controlled trials evaluating the effect of prescribed protein intake and identified outcomes. Articles were screened by 2 reviewers, risk of bias was assessed, data were synthesized quantitatively and narratively, and each outcome was separately graded for certainty of evidence. The literature search retrieved 25,384 articles and 2 trials were included in final analysis. No trials were identified that evaluated effect of protein amount on morbidities or mortality. Moderate certainty evidence found a significant difference in weight gain when protein intake of greater than 3.5 g/kg/day from preterm infant formula was compared with lower intakes. Low-certainty evidence found no evidence of effect of protein intake of 2.6 vs 3.1 vs 3.8 g/kg/day on length, head circumference, skinfold measurements, or mid-arm circumference. Low-certainty evidence found some improvement in development measures when higher protein intake of 3.8 vs 3.1 vs 2.6 g/kg/day were compared. Low-certainty evidence found no significant difference in bone mineral content when these protein intakes were compared. No studies were identified that compared protein intake greater than 4.0 g/kg/day. This systematic review found that protein intake between 3.5 and 4.0 g/kg/day promotes weight gain and improved development.
To evaluate adolescent athletes for cardiovascular (CV) abnormalities before engaging in competitive sports, the American Heart Association guidelines recommend preparticipation screening. The initiative aimed to implement a standardized protocol to increase the identification of CV abnormalities during athletic physical examinations.

A rapid-cycle model with four Plan-Do-Study-Act cycles was implemented in two urgent care clinics. Providers used a CV-specific screening checklist; parents were engaged in a discussion about the importance of this screening, and team engagement activities were used. Outcomes were measured with chart audits and surveys.

Because of the intervention, 62% of athletes were screened, with 29% identified as having a CV risk. The satisfaction of the patients and the team increased by 3% and 62.5%, respectively.

Despite competing foci in the clinics, athletes were properly screened using a standardized checklist, which is easily sustainable and can be duplicated in other settings.

Disorders of sodium and potassium are common and predictors of adverse outcome. Prevalence and impact on outcome of hypokalemia, hyperkalemia, hyponatremia and hypernatremia were investigated in emergency patients with community-acquired pneumonia (CAP).

Patients ≥18 years presenting to our emergency department between January 1st 2017 and December 31st 2018 with on-admission electrolyte measurements were included. Chart reviews were performed to identify patients with CAP.

19.948 cases had measurements of sodium and potassium of which 469 had CAP (2.4%). Prevalence of hypo- and hypernatremia was significantly increased in patients with compared to those without CAP (hyponatremia 28.8% vs. 10.5% respectively, p<0.0001; hypernatremia 1.9% vs. 0.6% respectively, p=0.002). The prevalence of hypo- and hyperkalemia was significantly higher in patients with than without CAP (hypokalemia 15.6% vs. 11.4% respectively, p=0.004; hyperkalemia 4.5% vs. 2.0% respectively, p=0.001). Hyponatremia was significantly associated with longer hospital stay in patients with CAP (regression coefficient 0.

Genetic conflict is considered a key driver in the evolution of reproductive systems with non-Mendelian inheritance, where parents do not contribute equally to the genetic makeup of their offspring. One of the most extraordinary examples of non-Mendelian inheritance is paternal genome elimination (PGE), a form of haplodiploidy which has evolved repeatedly across arthropods. Under PGE, males are diploid but only transmit maternally inherited chromosomes, while the paternally inherited homologues are excluded from sperm. This asymmetric inheritance is thought to have evolved through an evolutionary arms race between the paternal and maternal genomes over transmission to future generations. In several PGE clades, such as the mealybugs (Hemiptera Pseudococcidae), paternal chromosomes are not only eliminated from sperm, but also heterochromatinized early in development and thought to remain inactive, which could result from genetic conflict between parental genomes. Here, we present a parent-of-origin allele-specific transcriptome analysis in male mealybugs showing that expression is globally biased toward the maternal genome. However, up to 70% of somatically expressed genes are to some degree paternally expressed, while paternal genome expression is much more restricted in the male reproductive tract, with only 20% of genes showing paternal contribution. We also show that parent-of-origin-specific gene expression patterns are remarkably similar across genotypes, and that genes with completely biparental expression show elevated rates of molecular evolution. Our results provide the clearest example yet of genome-wide genomic imprinting in insects and enhance our understanding of PGE, which will aid future empirical tests of evolutionary theory regarding the origin of this unusual reproductive strategy.
Hydroxyurea (HU) is used in children with sickle cell disease (SCD) to increase fetal hemoglobin (HF), contributing to a decrease in physical symptoms and potential protection against cerebral microvasculopathy. https://www.selleckchem.com/products/atn-161.html There has been minimal investigation into the association between HU use and cognition in this population. This study examined the relationship between HU status and cognition in children with SCD.

Thirty-seven children with SCD HbSS or HbS/β0 thalassaemia (sickle cell anemia; SCA) ages 40-11 years with no history of overt stroke or chronic transfusion completed a neuropsychological test battery. Other medical, laboratory, and demographic data were obtained. Neuropsychological function across 3 domains (verbal, nonverbal, and attention/executive) was compared for children on HU (n = 9) to those not taking HU (n = 28).

Children on HU performed significantly better than children not taking HU on standardized measures of attention/executive functioning and nonverbal skills. Performance on verbal measures was similar between groups.

These results suggest that treatment with HU may not only reduce physical symptoms, but may also provide potential benefit to cognition in children with SCA, particularly in regard to attention/executive functioning and nonverbal skills. Replication with larger samples and longitudinal studies are warranted.

Whether AMPK regulates hippocampal neuronal development remains unclear. Hippocampal neurogenesis is abrogated after DNA damage. Here, we asked whether AMPK regulates adult hippocampal neurogenesis and its inhibition following irradiation. Adult Cre-lox mice deficient in AMPK in brain, and wild-type mice were used in a birth-dating study using bromodeoxyuridine to evaluate hippocampal neurogenesis. There was no evidence of AMPK or phospho-AMPK immunoreactivity in hippocampus. Increase in p-AMPK but not AMPK expression was observed in granule neurons and subgranular neuroprogenitor cells (NPCs) in the dentate gyrus within 24 hours and persisted up to 9 weeks after irradiation. AMPK deficiency in Cre-lox mice did not alter neuroblast and newborn neuron numbers but resulted in decreased newborn and proliferating NPCs. Inhibition of neurogenesis was observed after irradiation regardless of genotypes. In Cre-lox mice, there was further loss of newborn early NPCs and neuroblasts but not newborn neurons after irradiation compared with wild-type mice. These results are consistent with differential negative effect of AMPK on hippocampal neuronal development and its inhibition after irradiation.
The Global Digital Exemplar (GDE) Program is a national attempt to accelerate digital maturity in healthcare providers through promoting knowledge transfer across the English National Health Service (NHS). "Blueprints"-documents capturing implementation experience-were intended to facilitate this knowledge transfer. Here we explore how Blueprints have been conceptualized, produced, and used to promote interorganizational knowledge transfer across the NHS.

We undertook an independent national qualitative evaluation of the GDE Program. This involved collecting data using semistructured interviews with implementation staff and clinical leaders in provider organizations, nonparticipant observation of meetings, and key documents. We also attended a range of national meetings and conferences, interviewed national program managers, and analyzed a range of policy documents. Our analysis drew on sociotechnical principles, combining deductive and inductive methods.

Data comprised 508 interviews, 163 observed meetmay be effective in facilitating knowledge transfer among healthcare organizations, but need to be accompanied by other evolving methods, such as site visits and other networking activities, to iteratively transfer knowledge and experience.
Coronavirus disease 2019 (COVID-19) patients are at risk for resource-intensive outcomes including mechanical ventilation (MV), renal replacement therapy (RRT), and readmission. Accurate outcome prognostication could facilitate hospital resource allocation. We develop and validate predictive models for each outcome using retrospective electronic health record data for COVID-19 patients treated between March 2 and May 6, 2020.

For each outcome, we trained 3 classes of prediction models using clinical data for a cohort of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2)-positive patients (n = 2256). Cross-validation was used to select the best-performing models per the areas under the receiver-operating characteristic and precision-recall curves. Models were validated using a held-out cohort (n = 855). We measured each model's calibration and evaluated feature importances to interpret model output.

The predictive performance for our selected models on the held-out cohort was as follows area under the receiver-operating characteristic curve-MV 0.

Specifically, we have shown that anesthesia with the commonly used GA sevoflurane induces in exposed animals not only neuroendocrine abnormalities (somatic effects), but also epigenetic reprogramming of germ cells (germ cell effects). The latter may pass the neurobehavioral effects of parental sevoflurane exposure to the offspring, who may be affected even at levels of anesthesia that are not harmful to the exposed parents. The large number of patients who require general anesthesia, the even larger number of their future unexposed offspring whose health may be affected, and a growing number of neurodevelopmental disorders of unknown etiology underscore the translational importance of investigating the intergenerational effects of GAs. In this mini review, we discuss emerging experimental findings on neuroendocrine, epigenetic, and intergenerational effects of GAs.Background Total joint arthroplasty is one of the most common surgeries performed in the United States with total knee arthroplasty (TKA) being one of the most successful surgeries for restoring function and diminishing pain. Even with the demonstrated success of TKA and a higher prevalence of arthritis and arthritis related disability among minorities, racial and gender disparity remains a constant issue in providing care for the adult reconstruction patient. Aim To assess the role of demographics and expectations on differences in perioperative patient reported outcomes (PRO) following TKA. Methods One hundred and thirty-three patients scheduled for primary unilateral TKA secondary to moderate to severe osteoarthritis were enrolled in this two-institution prospective study. Validated PRO questionnaires were collected at four time points. Statistical analysis was conducted to determine the impact of gender, ethnic background and expectation surveys responses to assess PRO at these time points. Results Femalee patients. No postoperative differences in outcomes between these groups.Background Surgical site infections are a major cause of morbidity and mortality following orthopedic surgery. Recent efforts to identify sources of contamination in the operating rooms have implicated mobile phones. Aim To investigate microbial colonization on the mobile phones of health care professionals in the orthopedic operating room. Methods We conducted a cross-sectional study involving culture and sensitivity analysis of swabs taken from the mobile phones of orthopedic and anesthesia attendings, residents, technicians and nurses working in the orthopedic operating rooms over a period of two months. Demographic and cell phone related factors were recorded using a questionnaire and the factors associated with contamination were analyzed. Results Ninety-three of 100 mobile phones were contaminated. Species isolated were Coagulase-negative Staphylococcus (62%), Micrococcus (41%) and Bacillus (26%). The risk of contamination was increased with mobile covers and cracked screens and decreased by cell phone cleaning. Conclusion Mobile phones belonging to health care workers are frequently contaminated with pathogenic bacteria with the potential of transferring drug resistance to nosocomial pathogens. Studies investigating the relationship to surgical site infections need to be conducted. The concept of "mobile hygiene" involving the change of mobile covers, replacement of cracked screens or even wiping the phone with an alcohol swab could yield the cost-effective balance that contaminated cell phones deserve until they are established as a direct cause of surgical site infections.Maize ear rot caused by Fusarium verticillioides (Fv) is a major disease associated with reduced grain yield and ear quality. The use of biochar in management of ear rot has not been established. Efficacy of biochar aganst the disease was therefore investigated. Efficacy of biochars produced from poultry faecal waste (Bpw) and sawdust (Bsd) against pathogenic Fusarium verticillioides (Fv) causing ear rot in maize was determined using biochar treatment combinations (Bpw, Bsd, Bpw + Bsd, Bpw + Fv, Bsd + Fv, Bpw + Bsd + Fv, Fv and control) as soil amendments. Additional treatments consisted of fungicide (Cibaplus), poultry feacal waste (Pw), sawdust (Sd), Bpw + Fungicide, Bsd + Fungicide, Bpw + Bsd + Fungicide, Fungicide + Fv, and Pw + Sd. The Bpw and Pw at 1, 2 and 3 kg/m2 each, Bsd and Sd (0.50, 1.00 and 1.50 kg/m2) and fungicide (0.25, 0.50 and 1.00 g/L) were applied. Inoculation of pathogenic F. verticillioides strain was conducted at 7th week after planting and ear rot severity assessed at harvest. Residual effects of treatments were examined in the second season. Data gathered were subjected to ANOVA at α 0.05. https://www.selleckchem.com/products/bi-3802.html Maize treated with Sd, Bpw and Bpw + Fungicide scored 1-3% severity; Bpw + Bsd, Bsd, Fungicide, Pw + Sd, Bsd + Fv, Bsd + Fungicide, Bpw + Bsd + Fungicide, Bpw + Fv, Bpw + Bsd + Fv and Fungicide + Fv scored 4-10 %. Severity rating for control and Pw was 11-25 % while Fv was 26-50 %. Poultry faecal waste and Bpw based treatments recorded significant impact on growth characters across varying concentrations compared to other treatments. Poultry faecal waste biochar and sawdust biochar were effective in the management of Fusarium ear rot of maize and could be used as soil amendments.Worldwide, Helicobacter pylori (H. pylori) is regarded as the major etiological agent of peptic ulcer and gastric carcinoma. Claiming about 50 percent of the world population is infected with H. pylori while therapies for its eradication have failed because of many reasons including the acquired resistance against its antibiotics. Hence, the need to find new anti-H.pylori medications has become a hotspot with the urge of searching for alternative, more potent and safer inhibitors. In the recent drug technology scenario, medicinal plants are suggested as repositories for novel synthetic substances. Hitherto, is considered as ecofriendly, simple, more secure, easy, quick, and less toxic traditional treatment technique. This review is to highlight the anti-H. pylori medicinal plants, secondary metabolites and their mode of action with the aim of documenting such plants before they are effected by cultures and traditions that is expected as necessity.

The confluence of these new physical properties for conducting polymer hydrogels opens broad opportunities for a myriad of dynamic applications.The development of nanoagrochemicals has attracted much attention in the last decade to overcome the recent agricultural and environmental challenges associated with the intensive usage of insecticides. Herein, nanostructured calcium borate materials with hierarchical sea urchin-like microspheres and microblocks have been synthesized by a facile hydrothermal method. The insecticidal activity of CaB2O4 and its synergistic combination with cholinesterase-inhibiting insecticides are explored against Spodoptera littoralis (S. littoralis) for the first time via a feeding bioassay protocol. The insecticidal efficacy of sea urchin-like microspheres (CB-A) is estimated to be LC50 = 207 mg L-1 which is two-fold higher than that of microblocks (CBM-A) with LC50 = 406 mg L-1 after eleven days of exposure. The synergistic combination of the CB-A sample with methomyl and chlorpyrifos increases the toxicity to 2.4 and 2.6-fold higher than that of the individual insecticides, respectively. Significantly, sea urchin-like CaB2O4 microspheres cause physical damage to the external insect's cuticle layer, which consequently enhances the uptake of organic insecticides. Our results revealed that calcium borate micro-/nano-structures can be employed as a multifunctional nanoagrochemical in various agricultural programs for S. littoralis control and decrease the usage of cholinesterase-inhibiting insecticides.Research studies have shown that Lactobacillus fermentum generally exists in the human gut and has potential health benefits on host health due to its antimicrobial and antioxidant properties. However, the lack of an effective culture medium for the isolation of L. fermentum has presented a significant obstacle on the path to screen L. fermentum strains from the human intestinal tract with a large diversity of commensal microbes. In this study, a total of 51 Lactobacillus species are detected in 200 human fecal samples and we aim to distinguish L. fermentum from these common existing Lactobacillus species and design a more efficient culture medium for isolating L. fermentum strains from the human gut. Based on antibiotic susceptibility and sugar utilization tests, a new optimized medium called LFMATA containing arabinose as the carbon source and 20 mg L-1 vancomycin, 64 mg L-1 gentamicin and 256 mg L-1 streptomycin was developed. Genotype and phenotype analysis for antibiotic resistance and carbohydrate metabolism showed that though glycometabolism-related genes (araA, xylA, manX, bglX, treP and rbsK) correlated with the carbon utilization of Lactobacillus, the genes conferring resistance to streptomycin (gidB and rpsL) and gentamicin (tlyA) were not directly associated with the antibiotic resistance of Lactobacillus strains. This new selective medium greatly increased the efficiency of screening L. fermentum strains from human fecal samples, with the rate of L. fermentum isolation on LFMATA being 10-fold higher than that on LAMVAB.Correction for 'Recovery of the self-cleaning property of silicon elastomers utilizing the concept of reversible coordination bonds' by Yuxing Shan et al., Soft Matter, 2020, 16, 8473-8481, DOI .Psidguajones A and B, a pair of dimeric sesquiterpene-based meroterpenoid epimers, have been isolated from the leaves of Psidium guajava for the first time. Their structures were confirmed by comprehensive spectroscopic techniques combined with a comparison of experimental and calculated ECD data.Biopanning, a common affinity selection approach in phage display, has evolved numerous ligands for diagnosis, imaging, delivery, and therapy applications. However, traditional biopanning has suffered from time-consuming processes, highly-repetitive procedures and labor-intensive manual operation. Herein, a highly integrated and automated biopanning platform (Auto-Panning) is proposed. Based on digital microfluidics (DMF), biopanning processes are integrated on a chip with highly reproducible, precise, automated liquid manipulation. Therefore, 3 rounds of Auto-Panning can be accomplished within 16 h, instead of nearly a week of complicated manual operations. Auto-Panning has been used to evolve a specific peptide against cancer biomarker EphA2 with excellent cellular penetrating ability and significant invasion suppression biofunction, successfully demonstrating the practicality of the platform. Overall, as an automated programmable molecular screening platform, Auto-Panning will further promote the discovery and applications of novel ligands.When a suspension of charged nanoparticles is in contact with a like-charged water-solid interface, next to this interface a particle-free layer is formed. The present study provides reliable measurements of the thickness of this particle-free layer with three different techniques, namely optical reflectivity, quartz crystal microbalance (QCM), and direct force measurements with atomic force microscopy (AFM). Suspensions of negatively charged nanoparticles of different size and type are investigated. When the measured layer thickness is normalized to the particle size, one finds that this normalized thickness shows universal inverse square root dependence on the particle volume fraction. This universal dependence can be also derived from Poisson-Boltzmann theory for highly asymmetric electrolytes, whereby one has to assume that the nanoparticles represent the multivalent coions.A simple method, which takes place quickly in 5 min, is developed for the N-triflination of pyrazolones using CF3SO2Na (Langlois reagent) and phenyliodine(iii)bis(trifluoroacetate) (PIFA). This reaction takes place at the imine nitrogen centre instead of the more reactive C4-position, forming a new N-S bond. https://www.selleckchem.com/Bcl-2.html A variety of pyrazolone derivatives were subjected to the reaction. Unlike the previous reports on sulfenylation or sulfonylation of pyrazolone, wherein the corresponding C-S bond is formed, this new method leads to the formation of the hetero-hetero atom bond (N-S bond) at room temperature.
