Abstract Objectives Calcium/Calmodulin-dependent protein kinase-2 (CaMKII) is a serine/threonine kinase prevalent in neuronal cells, playing key role memory, learning, and synaptic plasticity. Nonspecific CaMKII inhibition can prevent apoptosis cells reduce glutamate-induced cell death. Additionally, variations CaMKK enzyme levels affect hemopoietic stem proliferation, although the effects of on responses during stress remain unclear. This study aims to explore CaMKII’s impact survival...

Abstract Objective : The examination of the urine remains to be one most commonly performed tests in laboratory practice. Currently, laboratories also need accredit their diagnostics by comparing measurement methods acceptable references. In this study we compared particle counts obtained new generation automated technique, image capture analysis (IQ‐200) with those a standardized chamber counts. Design and Methods same 258 samples from different departments hospital assayed IQ‐200 were...

Objective: Many of the vaccines developed for COVID-19 have been approved clinical emergency use before their safety and preclinical studies completed. The main aim this study was to investigate effects an inactivated SARS-CoV-2 virus vaccine (Vero cells) on renal function in Balb/C Albino mice. Methods: 21 healthy, 6– 8 week old BALB/c male mice were divided into three equal groups, 0.10 mL intramuscular saline dose volume administered first group. To second group, a single 120 U Vero cell...
