Two-dimensional speckle tracking echocardiography derived post systolic shortening in patients with unstable angina and normal left ventricular systolic function.

Objectives: Post systolic shortening (PSS) had been shown to be sensitive in detecting ischemia on stress echocardiography. This work aims to study the diagnostic potential of resting PSS and post systolic index (PSI) in patients with suspected unstable angina (UA).

Methods: Total of 159 participants with suspected UA without any wall motion abnormalities were recruited.

Assessment of Pulmonary Artery Pressures by Various Doppler Echocardiographic Parameters and its Correlation with Cardiac Catheterization in Patients with Pulmonary Hypertension.

Background: Measuring pulmonary artery pressures is a routine index in Doppler echocardiography to diagnose, risk stratify, and prognosticate patients with pulmonary hypertension (PH). There are numerous methods in use to measure it in routine clinical practice.

Objective: The objective of this study was to assess the correlation between the commonly used Doppler-derived parameters such as tricuspid regurgitation (TR)-derived systolic pulmonary artery pressure (SPAP), pulmonary regurgitation (PR)-derived mean pulmonary artery pressure (MPAP), and right ventricular outflow tract acceleration time (RVOT AcT) with right heart catheterization (RHC) data which are the gold standard.

Nanowires of polyaniline festooned silver coated paper electrodes for efficient solid-state symmetrical supercapacitors.

This paper demonstrates a facile strategy for the development of nanosilver decorated polyaniline coated (PAg) paper-based electrodes for the fabrication of solid-state symmetrical supercapacitors. PAg based printing paper was developed through a two-step process involving initial silver nucleation and growth on the paper followed by aniline polymerization. The developed electrically conductive paper exhibited a highly porous structure and excellent mechanical stability.

Flexible Electrochemical Transducer Platform for Neurotransmitters.

We have designed a flexible electrochemical transducer film based on PEDOT-titania-poly(dimethylsiloxane) (PTS) for the simultaneous detection of neurotransmitters. PTS films were characterized using various techniques such as transmission electron microscopy, scanning electron microscopy, atomic force microscopy, four probe electrical conductivity, ac-impedance, and thermomechanical stability. The electrocatalytic behavior of the flexible PTS film toward the oxidation of neurotransmitters was investigated using cyclic voltammetry and differential pulse voltammetry.

Complicated vivax malaria, an often underestimated condition - Case Report.

Malaria is a vector-borne disease that is endemic in 91 countries. South East Asia is the second most affected region in the world, with India carrying the highest burden of the disease. Four species of Plasmodium are known to cause malaria in humans.
