Structure-Activity Relationship of Ciprofloxacin towards S-Spike Protein of SARS-CoV-2: Synthesis and Evaluation.

The recent outbreak of the coronavirus (COVID-19) pandemic, caused by the SARS-CoV-2 virus, has posed serious threats to global health systems. Although several directions have been put by the WHO for effective treatment, use of antibiotics, particularly ciprofloxacin, in suspected and acquired Covid-19 patients has raised an even more serious concern of antibiotic resistance. Ciprofloxacin has been reported to inhibit entry of SARS-CoV-2 into the host cells via interacting with the spike (S) protein.

Age at Menarche Is Associated With Leg-Length Components Among the Adolescent Girls in West Bengal, India.

Background: The relationship between early age at menarche (AAM) and body height (HT), including its different segments has not been extensively studied among non Western populations. Lengths of the lower (distal) part of the leg, such as knee HT (KH) and tibial length (TbL), are considered to be sensitive indicators of living conditions during early growth and development. Life history theory predicts that within a survival challenge the growth of vital parts of the body shall be prioritized over less essential parts.

Mutational Landscape of Patients with Wiskott Aldrich Syndrome: Update from India.

Purpose: Wiskott-Aldrich syndrome (WAS) is an X-linked genetic disorder characterized by distinctive features including microthrombocytopenia, eczema and recurrent infections. In the present study we report clinical, immunological and molecular spectrum of 41 WAS patients diagnosed over last five years.

Methods: Clinical and family history was collected from case records.

Validation of reference genes for cardiac RT-qPCR studies spanning the fetal to adult period.

Many genes used as internal controls for mRNA expression studies are unstable (change) over development. This study determined an approach to validate reference genes for mRNA studies spanning the fetal period to adulthood in sheep hearts.•We determined the mRNA expression of 12 candidate reference genes (ACTB, GAPDH, H3-3A, HYAL2, PPIA, RNA18S1, RPL32, RPL37A, RPL41, RPLP0, RPS15, and YWHAZ) via RT-qPCR.

Comparative analysis of canine and human HtrA2 to delineate its role in apoptosis and cancer.

Therapeutically, targeting the pro- and anti-apoptotic proteins has been one of the major approaches behind devising strategies to combat associated diseases. Human high-temperature requirement serine protease A2 (hHtrA2), which induces apoptosis through both caspase-dependent and independent pathways is implicated in several diseases including cancer, ischemic heart diseases, and neurodegeneration, thus making it a promising target molecule. In the recent past, the canine model has gained prominence in the understanding of human pathophysiology that was otherwise limited to the rodent system.
