We present here CellML 2.0, an XML-based language for describing and exchanging mathematical models of physiological systems. MathML embedded in CellML documents is used to define the underlying mathematics of models. Models consist of a network of reusable components, each with variables and equations giving relationships between those variables. Models may import other models to create systems of increasing complexity. CellML 2.0 is defined by the normative specification presented here, prescribing the CellML syntax and the rules by which it should be used. The normative specification is intended primarily for the developers of software tools which directly consume CellML syntax. Users of CellML models may prefer to browse the informative rendering of the specification (https//cellml.org/specifications/cellml_2.0/) which extends the normative specification with explanations of the rules combined with examples of their usage.Objectives In order to explore Coffea canephora green seeds as natural extract for application in the functional-food industry, we focused this study to the evaluation of the antioxidant and the antiadhesion effect of C. canephora green seeds extracts. Methods The analysis of C. canephora green seeds extracts was carried out by RP-HPLC-PDA. These extracts were screened for antioxidant activities by ABTS and phenanthroline assays. The antibacterial activity was determined by microdilution method against three reference bacteria. The inhibition of bacterial adhesion at 1/8 MIC was carried out against three reference bacteria. Results The RP-HPLC-PDA revealed the presence of gallic acid, vanillin, quercetin, chlorogenic acid, and P-coumaric acid. The n-buatnol extract have the highest activity ABTS assays (3.96 ± 0.08 μg/mL). For this extract, the A0.5 was 1.90 ± 0.05 μg/mL for phenanthroline assay. The n-butanol extract and the methanolic extract have the higher antibacterial activity against Staphylococcus aureus ATCC 25923 (40 µg/mL).At MIC/8, the extracts of C. canephora showed 70% higher antidhesive activity against S. aureus ATCC 25923. Conclusions Our finding provides an effective and specific new approach to the search of antioxidant and antiadhesive compounds for different uses.
The use of kidney function and injury markers for early detection of drug-related glomerular or tubular kidney injury in infants, children and adolescents requires age-specific data on reference intervals in a pediatric healthy population. This study characterizes serum values for eight kidney function and injury markers in healthy infants, children and adolescents.

A single center prospective observational study was conducted between December 2018 and June 2019. Serum samples from 142 healthy infants, children and adolescents aged between 0 and≤15 years were collected. Statistical analyses for eight markers (albumin (ALB), β2-microglobulin (B2M), β-trace protein (BTP), creatinine (SCR), cystatin C (CYSC), kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), uromodulin (URO)) were performed to obtain reference intervals and associations with age, sex and weight were investigated (Pearson correlation, linear and piecewise regression).

ALB and SCR increased with age (p<0 detection of glomerular and tubular injury in infancy, childhood and adolescence.
External quality assessment (EQA) with commutable samples is used for assessing agreement of results for patients' samples. We investigated the feasibility to aggregate results from four different EQA schemes to determine the bias between different measurement procedures and a reference target value.

We aggregated EQA results for creatinine from programs that used commutable EQA material by calculating the relative difference between individual participant results and the reference target value for each sample. The means and standard errors of the means were calculated for the relative differences. Results were partitioned by methods, manufacturers and instrument platforms to evaluate the biases for the measurement procedures.

Data aggregated for enzymatic methods had biases that varied from-8.2 to 3.8% among seven instrument platforms for creatinine at normal concentrations (61-85μmol/L). EQA schemes differed in the evidence provided about the commutability of their samples, and in the amount of detailipants are needed to improve the ability to aggregate the results for optimal assessment of performance of measurement procedures. Aggregating data from a larger number of EQA schemes is feasible to assess trueness on a global scale.<b>Introduction </b>Pressure ulcers and their consequences can occur in any patient regardless of the underlying disease, so the knowledge of their prevention and treatment is extremely important. <br><b>The aim of the study</b> The aim of the study was to analyze the state of students' knowledge on pressure ulcers.<br><b> Material and methods</b> The research was carried out in the Pomeranian Medical University in Szczecin among students of nursing. The study involved 203 full-time students. Data was collected using a questionnaire consisting of 27 questions. The questions addressed the issues of the formation, prevention and treatment of pressure ulcers. The Kolmogorow-Smirnow, Fisher-Snedecor test, (ANOVA) with Spearman's correlation and Student's t-test were applied for statistical analysis. The statistical significance was assumed to be p ≤ 0.05. <br><b>Results</b> Over half of the respondents (57.64%) had a sufficient level of knowledge on pressure ulcers prevention and treatment. The level increased with the duration of the study, the highest was in the last few years, both I and II cycle of studies. The better (the higher) subjects assessed their knowledge about prevention and treatment of pressure ulcers, they were characterized by a higher level of knowledge. <br><b>Conclusions</b> The knowledge of nursing students on pressure ulcers increases with subsequent years of study. The selfassessment of students' knowledge about pressure ulcers, their prevention and treatment is accurate. Students of the consecutive years are better prepared to carry out anti-bedsore prevention. https://www.selleckchem.com/products/Gefitinib.html Students are aware of the need to have knowledge, as well as practice in the field of prevention and treatment of pressure ulcers.
