Coronavirus Disease 2019 (COVID-19) is a viral pneumonia emerged in December 2019 in Wuhan, China. Its cause is a new virus from the coronavirus family scientifically named Coronavirus Acute Respiratory Syndrome 2 (SARS-CoV-2). In this review study, articles published in English until March 23, 2020 on new coronavirus infection were reviewed. These articles are obtained by searching in PubMed, ...

Desquamation is described as a protease-dependent phenomenon where serine proteases with a basic pH optimum play a key role. Recently proteases with an acidic pH optimum were identified in the stratumcorneum and associated with desquamation, e.g., cathepsin D and the stratum corneum thiol protease. The purpose of this study was to investigate if human stratum corneum contains proteases differen...

This experimental study was designed to determine if caspase-3-like protease is activated during a short period of ischemia - reperfusion (I-R) that did not induce apoptosis, and whether protease-3-protease inhibitor could prevent myocardial I-R injury, especially necrotic cell death. The subjects were 20 isolated rat hearts; 10 were pretreated for 20 min with 100 micromol/L of the protease-3-p...

Since its outbreak, the severe acute respiratory syndrome—coronavirus 2 (SARS-CoV-2) has impacted quality of life and cost hundreds-of-thousands lives worldwide. Based on global spread mortality, there is an urgent need for novel treatments which can combat this disease. To date, 3-chymotrypsin-like protease (3CLpro), also known as main protease, considered among most important pharmacological ...

the date palm fruit stalk borer is one of the most important pests of date palm in the world. biochemical properties of digestive proteases in oryctes elegans prell larvae were investigated in this research and optimal total proteolytic and trypsin activities were obtained at ph 9.0 and 11.0, respectively. activity staining of protease on sds-page showed one isoform. also, zymogram pattern of t...

Methylmercury (MeHg) has been implicated to induce massive neurodegeneration by disruption of neuron-glia interactions besides a direct potent neurotoxicity. In the present study, we examined potential cytotoxic effects of MeHg on primary cultured rat microglia. Following treatment with a relatively low concentration (0.5 microM) of MeHg, microglia had induced cell death accompanied by DNA frag...
