Clinical profile of children with influenza like illness during pre-monsoon at coastal Karaikal, Puducherry, India.

Influenza infections in developing countries are under reported and WHO estimates that nearly 99% of influenza deaths worldwide occur in children under-five years of age in Asian and African countries. Consequently, this study aims to analyze the use of clinical profile and easily available laboratory parameters to aid identification of the possible viral etiology in the setting of pre-monsoon ILI. A cross-sectional study was carried out for three months among children with ILI attending fever clinic of a tertiary care hospital in Karaikal, South India.

Dysregulation of angiogenesis might lead to tissue ischemia (resulting from reduced blood vessel formation) or major diseases such as cancer (abnormal vascular growth).

Lanthanum vanadate-based carbon nanocomposite as an electrochemical probe for amperometric detection of theophylline in real food samples.

Based on a cutting-edge hybrid nanocomposite, this study was used to construct an electrochemical sensor for the accurate detection of THP.

Finite-time stability analysis and control of stochastic SIR epidemic model: A study of COVID-19.

In this paper, we present a finite-time stability analysis of a stochastic susceptible-infected-recovered (SIR) epidemic compartmental model with switching signals. The model includes a linear parameter variation (LPV) and switching system that represents the impact of external factors, such as changes in public health policies or seasonal variations, on the transmission rate of the disease.

Evaluation of a collisional radiative model for electron temperature determination in hydrogen plasma.

A collisional-radiative (CR) model that extracts the electron temperature, T, of hydrogen plasmas from Balmer-line-ratio measurements is examined for the plasma electron density, n, and T ranges of 10-10 cm and 5-500 eV, respectively. The CR code, developed and implemented in Python, has a forward component that computes the densities of excited states up to n = 15 as functions of T, n, and the molecular-to-atomic neutral ratio r(H/H). The backward component provides n and r(H/H) as functions of the Balmer ratios to predict the T.

Prevalence of gastrointestinal parasites in bonnet macaque and possible consequences of their unmanaged relocations.

Relocation is one of the mitigating measures taken by either local people or related officers to reduce the human-bonnet macaque Macaca radiata conflict in India. The review on relocations of primates in India indicates that monkeys are unscreened for diseases or gastrointestinal parasites (henceforth endoparasites) before relocation. We collected 161 spatial samples from 20 groups of bonnet macaque across their distribution range in south India and 205 temporal samples from a group in Chiksuli in the central Western Ghats.
