An Overview on the Zoonotic Aspects of COVID-19.

Disruption of pristine natural habitat has a strong positive correlation with this increase in pandemics and thus, the zoonotic aspects are the most important part to uncover scientifically. On the other hand, containment and mitigation are the two basic strategies to stop a pandemic. The route of infection is of utmost importance for any pandemic and often left behind in combating the fatalities in real time.

Resurgence of hypertension and cardiovascular diseases in patients recovered from COVID-19: An Indian perspective.

Objective: The aim of this study was to understand the prevalence, extent, clinical approach of hypertension and cardiovascular disease (CVD) in patients recovered from COVID-19.

Methods: The round table meetings (RTMs) and survey convened a diverse panel of specialists including cardiologists, endocrinologists, diabetologists, consultant physicians, and family physicians from various geographical zones of India. A standard questionnaire including 10 questions was developed pertaining to the resurgence of hypertension and CVD in patients recovered from COVID-19.

Varying VA intervals during Para-Hisian pacing maneuver-What is the mechanism?

Inadvertent direct atrial capture and pure his capture can result in variable findings during parahis pacing manoeuvre (PHP). Understanding the results and positioning the pacing bipole towards ventricular aspect (distal his region) is helpful to avoid ambiguous results during PHP.

Change in VA interval by a single atrial premature depolarization - What is the mechanism?

A long VA tachycardia during a typical atrioventricular nodal reentrant tachycardia (AVNRT) can be a concomitant atypical AVNRT, atrial tachycardia or rarely atrio-ventricular reentrant tachycardia (AVRT). There are reported associations of AVNRT with other tachycardia substrates. Maneuvers are useful for differentiating the mechanism of the second tachycardia.

Antibacterial efficacy of leaf extracts of Combretum album Pers. against some pathogenic bacteria.

Background: Plant derived medicines show significant contributions to mankind in treating infections of pathogenic bacteria. Recently plants are used in pharmaceutical industries for novel drug preparations because to ensure efficacy and safety as synthetic antibiotics are threatened for their multidrug resistance. The present study aimed at finding antibacterial potential of aqueous and ethanolic leaf extracts of Combretum album.

Control of human filarial vector, Culex quinquefasciatus Say 1823 (Diptera: Culicidae) through bioactive fraction of Cayratia trifolia leaf.

Objective: To investigate the mosquito larvicidal activity of Cayratia trifolia (L.) Domin (Vitaceae: Vitales) (C. trifolia) which is distributed in many parts of India with medicinal properties as vector control is facing threat due to the emergence of resistance to synthetic insecticides.
