A DFT study of the adsorption behavior and sensing properties of CO gas on monolayer MoSe in CO-rich environment.

Context: Carbon monoxide, also known as the "silent killer," is a colorless, odorless, tasteless, and non-irritable gas that, when inhaled, enters the bloodstream and lungs, binds with the hemoglobin, and blocks oxygen from reaching tissues and cells. In this work, the monolayer MoSe-based CO gas sensors were designed using density functional theory calculation with several dopants including Al, Au, Pd, Ni, Cu, and P. Here, Cu and P were found to be the best dopants, with adsorption energies of -0.

A survey of surveys: an evaluation of the quality of published surveys in neurosurgery.

Purpose: Surveys generate valuable data in epidemiologic and qualitative clinical research. The quality of a survey depends on its design, the number of responses it receives, and the reporting of the results. In this study, we aimed to assess the quality of surveys in neurosurgery.

Myths, beliefs, and attitude toward cancer among the family caregivers of cancer patients: A community-based, mixed-method study in rural Tamil Nadu.

Background And Aim: Family support is one of the most crucial components of cancer care. The familial beliefs and myths associated with cancer can seriously affect the quality of life and treatment outcome of cancer patients. This study intends to explore the prevailing myths, beliefs, and attitude toward cancer among the family caregivers of cancer patients.

COMMENT: Ethics and professionalism of a community health worker: A virtue ethics approach.

Community health workers are the link between the community and the health system, delivering primary care services at the frontline. Every profession has its own ethics and professional values, and there is a need to formulate the ethics of community health work which should be informed by their rich experiential wisdom. In one such effort, we interviewed a senior community health worker in the Tamil Nadu health system and present it here as a virtue ethics case study.

Assessment of the mechanical properties of monolayer graphene using the energy and strain-fluctuation methods.

Molecular statics and dynamics simulations were performed to investigate the mechanical properties of a monolayer graphene sheet using an efficient energy method and strain-fluctuation method. Using the energy method, we observed that the mechanical properties of an infinite graphene sheet are isotropic, whereas for a finite sheet, they are anisotropic. This work is the first to report the temperature-dependent elastic constants of graphene between 100 and 1000 K using the strain-fluctuation method.

Amalaki rasayana, a traditional Indian drug enhances cardiac mitochondrial and contractile functions and improves cardiac function in rats with hypertrophy.

We evaluated the cardioprotective effect of Amalaki Rasayana (AR), a rejuvenating Ayurvedic drug prepared from Phyllanthus emblica fruits in the reversal of remodeling changes in pressure overload left ventricular cardiac hypertrophy (LVH) and age-associated cardiac dysfunction in male Wistar rats. Six groups (aging groups) of 3 months old animals were given either AR or ghee and honey (GH) orally; seventh group was untreated. Ascending aorta was constricted using titanium clips in 3 months old rats (N = 24; AC groups) and after 6 months, AR or GH was given for further 12 months to two groups; one group was untreated.

Acute outcome of treating patients admitted with electrical storm in a tertiary care centre.

Background: Electrical storm (ES) is a life threatening emergency. There is little data available regarding acute outcome of ES.

Aims: The study aimed to analyze the acute outcome of ES, various treatment modalities used, and the factors associated with mortality.

Directional anisotropy, finite size effect and elastic properties of hexagonal boron nitride.

Classical molecular dynamics simulations have been performed to analyze the elastic and mechanical properties of two-dimensional (2D) hexagonal boron nitride (h-BN) using a Tersoff-type interatomic empirical potential. We present a systematic study of h-BN for various system sizes. Young's modulus and Poisson's ratio are found to be anisotropic for finite sheets whereas they are isotropic for the infinite sheet.

Temperature dependent structural properties and bending rigidity of pristine and defective hexagonal boron nitride.

Structural and thermodynamical properties of monolayer pristine and defective boron nitride sheets (h-BN) have been investigated in a wide temperature range by carrying out atomistic simulations using a tuned Tersoff-type inter-atomic empirical potential. The temperature dependence of lattice parameter, radial distribution function, specific heat at constant volume, linear thermal expansion coefficient and the height correlation function of the thermally excited ripples on pristine as well as defective h-BN sheet have been investigated. Specific heat shows considerable increase beyond the Dulong-Petit limit at high temperatures, which is interpreted as a signature of strong anharmonicity present in h-BN.

Spinal Epidural Varices, a great Mimic of Intervertebral Disc Prolapse - A Case Series.

Introduction: Epidural venous plexus enlargement, presenting with low back pain and radiculopathy, is an uncommon cause of nerve roots impingement. This condition commonly mimics a herniated nucleus pulposus radiologically. The radiological diagnosis is often missed and the diagnosis is made during the surgery.

Acute phase reactants predict mitral regurgitation following mitral valvuloplasty.

This report evaluated whether acute phase reactants can predict the development of mitral regurgitation following percutaneous mitral valvotomy. 58 patients who developed significant mitral regurgitation following valvotomy were retrospectively compared with 58 age, sex and procedure technique matched control patients, who had valvotomy without mitral regurgitation. ESR and total leucocyte count were significantly higher in the group who developed mitral regurgitation, than in the control group.

Evaluation of the hemi-Cincinnati incision for posteromedial soft-tissue release in clubfoot.

Posteromedial soft-tissue release operations were performed on 42 idiopathic clubfeet in children younger than 2 years of age through the medial half of the Cincinnati incision (the hemi-Cincinnati incision). This incision gave adequate exposure to all structures to be released. Wound closure was possible in all 42 feet without having to hold the foot in plantarflexion or inversion.
