Trajectories and correlates of mental health among urban, school-age children during the COVID-19 pandemic: a longitudinal study.

Background: The COVID-19 pandemic posed numerous obstacles to psychosocial wellbeing for children. We conducted a longitudinal study to evaluate child mental health and social risks during the pandemic.

Methods: Participants were 172 caregivers of children aged 6-11 years old who attended well child visits within 6 months before pandemic onset at an urban safety net hospital in the US.

Changes in psychosocial functioning among urban, school-age children during the COVID-19 pandemic.

Background: There is concern about the effect of the COVID-19 pandemic on psychosocial functioning among school-age children, who have faced unusual stressors during this time. Our goal was to assess mental health symptoms and social risks during COVID-19, compared to before the pandemic, for urban, racial and ethnic minority school-age children, and investigate the relationship between mental health and social risks.

Methods: We conducted a cohort study from September 2019 until January 2021 of children age 5-11 years old recruited from an urban safety net hospital-based pediatric primary care practice.

[Live style and risk of lifestyle diseases].

Metabolic syndrome included obesity, diabetes mellitus type II, hypertension and disorder of lipid metabolism are serious complication affecting many people of economic advanced countries. Unhealthy live style with limited physical activity and overfeeding are the main cause of this disorder. Adjustment of the live style with regular physical activity has the better result compared with a diet intervention alone.

Identification of N-glycosylation in prolyl endoprotease from Aspergillus niger and evaluation of the enzyme for its possible application in proteomics.

An acidic prolyl endoprotease from Aspergillus niger was isolated from the commercial product Brewers Clarex to evaluate its possible application in proteomics. The chromatographic purification yielded a single protein band in sodium dodecyl sulfate polyacrylamide gel electrophoresis providing an apparent molecular mass of 63 kDa and a broad peak (m/z 58,061) in linear matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) mass spectrometry (MS) indicating the glycoprotein nature of the enzyme. Indeed, a colorimetric assessment with phenol and sulfuric acid showed the presence of neutral sugars (9% of weight).

[Relation between serum leptin levels and selected nutritional parameters in hemodialyzed patients].

Leptin is a protein hormone produced predominantly by adipocytes. Its serum concentrations positively correlate with body fat content and body mass index (BMI) i.e.
