Estimating The Possible Role Of Testing Capacity And Social Distancing In Predicting The Growth Rate Of Daily Covid-19 Cases.

Background: The purpose of this study was to estimate the effect of social distancing (days since the imposition of a lock-down) and the number of daily tests conducted per million population on the daily growth rate of COVID-19 cases.

Methods: After excluding the first 30 days since the announcement of an index case in a country, relevant data for the next forty days was collected from four countries: Belgium, Italy, South Korea and United Kingdom. Two online databases: Our World in Data and worldometer were used for the collection of data which included the number of new COVID-19 cases and the number of tests conducted on a given day.

Nanoniosome-encapsulated levoflaxicin as an antibacterial agent against Brucella.

A study was conducted to examine the prevalence of brucellosis (in animal farms) in the vicinity of Islamabad and Rawalpindi. A total of 170 milk samples were collected randomly from several farmhouses. The collected milk samples were initially screened by a Brucella selective medium.

Loss of caveolin-1 impairs retinal function due to disturbance of subretinal microenvironment.

Caveolin-1 (Cav-1), an integral component of caveolar membrane domains, is expressed in several retinal cell types, including photoreceptors, retinal vascular endothelial cells, Müller glia, and retinal pigment epithelium (RPE) cells. Recent evidence links Cav-1 to ocular diseases, including autoimmune uveitis, diabetic retinopathy, and primary open angle glaucoma, but its role in normal vision is largely undetermined. In this report, we show that ablation of Cav-1 results in reduced inner and outer retinal function as measured, in vivo, by electroretinography and manganese-enhanced MRI.
