The power system always has several variations in its profile due to random load changes or environmental effects such as device switching effects when generating further transients. Thus, an accurate mathematical model is important because most system parameters vary with time. Curve modeling of power generation is a significant tool for evaluating system performance, monitoring and forecasting. Several numerical techniques compete to fit the curves of empirical data such as wind, solar, and demand power rates...

A quadrivalent MMRV (measles-mumps-rubella-varicella) combination vaccine has recently been launched in India. This vaccine is highly immunogenic, with seroconversion rates against all antigens reaching 96.6-100% at 42 to 56 days after the second vaccine dose in unvaccinated children or in those previously vaccinated with MMR+/-V. Two doses efficacy, against all varicella is 94.1% and effectiveness reaches 91%. The most frequent solicited local adverse event after MMRV vaccine is redness, and fever is the most common solicited general symptom...

Point-of-care ultrasound (POCUS) is rapidly emerging as a bedside diagnostic tool that can enhance physical diagnosis and facilitate clinical decision making. Although ultrasound is widely used by nephrologists for vascular access and kidney imaging, diagnostic POCUS skills in other anatomic areas are not part of routine nephrology training. In this narrative review, we will provide an overview of selected POCUS techniques, highlight potential uses of POCUS in routine nephrology practice, and describe a new curriculum implemented at Johns Hopkins University School of Medicine to teach diagnostic POCUS skills to nephrology fellows...

A validation study for six genomic regions previously identified by a genome-wide association study for somatic cell score was conducted with data of clinical mastitis in German Holstein cattle. Out of 10 tested SNPs, five on chromosomes 6, 13 and 19 were significantly associated with clinical mastitis (P < 0.05). Three SNPs on chromosomes 6 and 19 had the same direction of effect as those previously reported in the initial genome-wide association study for somatic cell score. The other two SNPs on chromosome 13 had opposite effects...

Ecto-nucleotidase members i.e., ecto-5'-nucleotidase and alkaline phosphatase, hydrolyze extracellular nucleotides and play an important role in purinergic signaling. Their overexpression are implicated in a variety of pathological states, including immunological diseases, bone mineralization, vascular calcification and cancer, and thus they represent an emerging drug targets. In order to design potent and selective inhibitors, new derivatives of 4-aminopyridine have been synthesized (10a-10m) and their structures were established on the basis of spectral data...

BACKGROUND: As access to antiretroviral therapy in sub-Saharan Africa continues to expand, more women with HIV can expect to survive through their reproductive years. Modern contraceptives can help women choose the timing and spacing of childbearing. However, concerns remain that women with HIV who use non-barrier forms of modern contraception may engage in more condomless sex because of their decreased risk of unintended pregnancy. We examined whether non-barrier modern contraceptive use by HIV-positive female sex workers was associated with increased frequency of recent condomless sex, measured by detection of prostate-specific antigen (PSA) in vaginal secretions...

An increasing body of experimental and clinical evidence suggests that p-cresol sulfate and indoxyl sulfate contribute to the high cardiovascular burden in patients with chronic kidney disease. In a post hoc analysis on the HEMO trial, Shafi et al. failed to confirm an association between total p-cresol sulfate and indoxyl sulfate and cardiovascular outcomes in dialysis patients. Analytical issues and case-mix may explain the discrepant findings.

The main challenge in the lead removal simulation is the behaviour of non-linearity relationships between the process parameters. The conventional modelling technique usually deals with this problem by a linear method. The substitute modelling technique is an artificial neural network (ANN) system, and it is selected to reflect the non-linearity in the interaction among the variables in the function. Herein, synthesized deep eutectic solvents were used as a functionalized agent with carbon nanotubes as adsorbents of Pb(2+)...

BACKGROUND: Few studies describe the community-acquired pneumonia (CAP) burden in children in Asia. We estimated the proportion of all CAP hospitalizations in children from nine hospitals across the Republic of Korea (high-income), Indonesia, Malaysia (middle-income), and Vietnam (low/middle-income). METHODS: Over a one or two-year period, children <5 years hospitalized with CAP were identified using ICD-10 discharge codes. Cases were matched to standardized definitions of suspected (S-CAP), confirmed (C-CAP), or bacterial CAP (B-CAP) used in a pneumococcal conjugate vaccine efficacy study (COMPAS)...
