Neurodegenerative diseases (NDDs) like Alzheimer's and Parkinson's, characterized by gradual loss of neuronal structure and function, results in cognitive and motor impairments. These complex disorders involve multiple pathogenic mechanisms, including neurotransmitter imbalances, oxidative stress, and protein misfolding, necessitating multifunctional therapeutic approaches. Piperidine and isatin are valuable scaffolds in drug design due to their favorable pharmacokinetic profiles, ability to cross blood-brain barrier, and ease of modification.

Purpose: Soft tissue sarcomas (STS) due to their aggressive nature, pose challenges in achieving optimal local control (LC) rates following surgery. Brachytherapy offers precise delivery of high radiation doses to target tissues, potentially enhancing LC rates. This feasibility study explored the efficacy of perioperative high-dose-rate brachytherapy (PHDRB) and external beam radiation therapy (EBRT) in improving LC rates for STS, with a particular focus on interstitial brachytherapy and dose escalation strategies for high-risk patient sub-groups.

The pink or hibiscus mealybug, Maconellicoccus hirsutus, is a serious pest of grapes, jute, and mesta, causing severe yield losses in India and other countries. Chemical control remains the foremost choice for farmers to manage this pest. As insecticides break down over time due to biotic and abiotic factors, insects are exposed to varying levels of these exogenous compounds.

Maconellicoccus hirsutus is a highly polyphagous insect pest, posing a substantial threat to various crop sp., especially in the tropical and sub-tropical regions of the world. While extensive physiological and biological studies have been conducted on this pest, the lack of genetic information has hindered our understanding of the molecular mechanisms underlying its growth, development, and xenobiotic metabolism.

Fruit crops are frequently subjected to biotic and abiotic stresses that can significantly reduce the absorption and translocation of essential elements, ultimately leading to a decrease in crop yield. It is imperative to grow fruits and vegetables in areas prone to drought, salinity, and extreme high, and low temperatures to meet the world's minimum nutrient demand. The use of integrated approaches, including supplementation of beneficial elements like silicon (Si), can enhance plant resilience under various stresses.

Article Synopsis
  • * Researchers analyzed 3 mitochondrial DNA regions from 176 catfish samples, uncovering high gene diversity and low to moderate genetic differentiation among populations, along with three distinct genetic clades not tied to specific rivers.
  • * The findings suggest a recent population expansion of W. attu around 0.04 million years ago, providing important insights for conservation efforts and sustainable management of this valuable species in the Ganga River System.

Unlabelled: Genetic diversity is the primary source of variability in any crop improvement program, and the diverse germplasm of any crop species represents an important genetic resource for gene or allele mining to meet future needs. Huge genetic and phenotypic diversity is present in the apple gene pool, even though, breeding programs have been mainly focused on a few traits of interests, which have resulted in the reduction of the diversity in the cultivated lines of apple. Therefore, the present study was carried out on 70 diverse apple genotypes with the objective of analyzing the genetic diversity and to identify the genetic loci associated with important fruit quality traits.

Article Synopsis
  • - The study aimed to assess the prevalence of ventilator-associated events (VAE) and the antibiotic resistance patterns of bacterial infections in ventilator-associated pneumonia (VAP) within an ICU in Uttarakhand, highlighting VAP as a major cause of hospital-acquired infections (HAI).
  • - A total of 1,220 patients were monitored; 6.4% were diagnosed with VAE, which progressed to different infection-related conditions, with the significant presence of certain bacteria among the isolates.
  • - Effective early antibiotic treatment is crucial for improving patient outcomes, with colistin being the most effective antibiotic against the detected organisms, although challenges in diagnosing VAP remain.

Background: Allergic rhinitis is largely treated by using antihistamines and nasal sprays, either alone or in combination. However, these measures ease out the symptoms but do not address causative factors, and have their share of side effects and limitations. An Ayurvedic herbo-mineral formulation, IMMBO, has been reported to be effective in treating allergic rhinitis.

Background: Positive portrayals of tobacco use in entertainment media can normalize and perpetuate use. In 2012, the Government of India implemented the Tobacco-Free Film and Television Rules, a first-of-its-kind comprehensive regulation to restrict tobacco depiction in films and television programs. Two complementary studies were undertaken to assess the implementation of the film rules on television and in movie theaters.

Article Synopsis
  • Plants rely on intracellular signaling molecules to manage their immune responses, since they lack a humoral defense system like animals.
  • Pathogens trigger calcium ion accumulation in plant cells, which creates calcium signatures that activate defense-related proteins, such as calmodulins and calcium-dependent protein kinases.
  • Recent biotechnological advances have highlighted the significance of calcium signaling in plant defenses against microbes, offering potential avenues for enhancing plant resistance to pathogens.
