The landscape of chronic liver disease has changed significantly, with metabolic dysfunction-associated steatotic liver disease (MASLD) now emerging as the most widespread form worldwide. In Asia, particularly in India, the prevalence of MASLD is increasing, largely driven by poor dietary habits and a sedentary way of life. MASLD spans from fat deposition to inflammation and fibrosis.

Hepatic encephalopathy (HE) is a frequent decompensation in patients with cirrhosis, which significantly affects morbidity and mortality. Ammonia is a major neurotoxin implicated in the pathogenesis, progression, and severity of HE, and various organs including the gut, muscle, kidney, and brain are involved in its metabolism. Therefore, therapeutic management involves reducing ammonia production and increasing its elimination from the blood and the brain.

In eastern India, zinc (Zn) has emerged as the most critical micronutrient impacting the yield of rice. Experiments were conducted for 2 years during the Rabi and Kharif rice seasons at 339 on-farm locations in five districts and four agroclimatic zones of Odisha state in eastern India to study the management of Zn in rice nurseries and the transplanted crop. At each location, five treatment plots were established in which nitrogen (N), phosphorus (P) and potassium (K) were applied to rice following site-specific nutrient management as guided by Rice Crop Manager (RCM), a web-based tool.

Soil microbial species diversity and distribution of microbial communities are vital for soil and crop health, nutrient cycling, availability, and subsequent plant growth. These soil dynamics are highly influenced and altered by various soil management practices, inputs, and agricultural techniques. In the present study, the effects of chemical and organic management practices on soil microbial diversity and community structure were examined and compared using amplicon sequencing of the 16S and ITS regions.

Acute-on-chronic liver failure (ACLF) is a condition associated with high mortality in the absence of liver transplantation. There have been various definitions proposed worldwide. The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set in 2004 on ACLF was published in 2009, and the "APASL ACLF Research Consortium (AARC)" was formed in 2012.

Introduction: Aloe vera is widely known for its therapeutic properties, but concerns regarding the levels of phytohormones and their potential impact on human health highlight the need for advanced analytical techniques. This study aims to develop and validate a sensitive method for the determination of six key phytohormones in Aloe vera using Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS).

Methods: A validated LC-MS/MS method was optimized for the determination and quantification of six phytohormones in Aloe vera: Abscisic Acid (ABA), Salicylic Acid (SA), Indole-3-Acetic Acid (I3AA), Gibberellic Acid (GA), 6-Benzylaminopurine (6BAP), and Isopentenyladenine (ISA).

This research explores the relationships among soil characteristics, carbon dynamics, and soil biome in rice-based cropping systems across four farming scenarios: conventional farming, organic farming with conventional tillage, integrated nutrient management, and conservation agriculture with zero tillage. Conducted at the International Rice Research Institute, India (2020-2022), the study analyzed physical, chemical, and biological soil parameters. The findings reveal significant effects of farming scenarios on soil organic carbon (SOC), available nitrogen (N), phosphorus (P), and potassium (K), with no notable impact on bulk density, pH, electrical conductivity, or water-holding capacity.

Article Synopsis
  • Researchers measured serum calprotectin levels in 79 pregnant women with ICP, 43 without ICP, and 59 non-pregnant women, finding that calprotectin levels were significantly higher in all pregnant women compared to non-pregnant women.
  • However, calprotectin did not effectively distinguish between pregnant women with and without ICP, showing inferior diagnostic performance compared to serum bile acid, highlighting its limitations as a diagnostic marker for ICP.

  • Sheehan syndrome happens when a part of the pituitary gland gets damaged after a woman has heavy bleeding after giving birth.
  • Symptoms can include not being able to produce milk and missing periods, and sometimes it can become serious if there are other health issues, like with adrenal glands.
  • In a case study, a 45-year-old woman got very sick with a dengue infection and was diagnosed with Sheehan syndrome, which led to her needing hormone treatment to feel better.

Introduction: Severe alcohol-associated hepatitis (SAH) carries high 1-month mortality. Corticosteroids provide a modest 28-day but not 90-day survival benefit, due to development of infections and organ failures. Granulocyte colony-stimulating factor (GCSF) has shown promise in patients with SAH by its immunomodulatory and regenerative capabilities.

Background: The advent of coronavirus disease 2019 (COVID-19) unveiled the worst national blood crisis that the United States had witnessed in over a decade. With the pandemic influencing the different stages of the acquisition of blood products outside the hospital setting, we aimed to explore the possible barriers contributing to the shortage of blood products within the medical community.

Aim: To assess the adherence to restrictive blood transfusion practices for patients in the COVID era and pre-COVID era.

Objectives: Sabkhas represent polyextreme environments characterized by elevated salinity levels, intense ultraviolet (UV) radiation exposure, and extreme temperature fluctuations. In this study, we present the complete genomes of five bacterial isolates isolated from the sabkha-shore region and investigate their genomic organization and gene annotations. A better understanding of the bacterial genomic organization and genetic adaptations of these bacteria holds promise for engineering microbes with tailored functionalities for diverse industrial and agricultural applications, including bioremediation and promotion of plant growth under salinity stress conditions.

The survival of humanity is severely threatened by the massive accumulation of waste in the ecosystem. One plausible solution for the management and upcycling of waste is conversing waste at the molecular level and deriving carbon-based nanomaterial. The field of carbon nanomaterials with distinctive properties, such as exceptionally large surface areas, good thermal and chemical stability, and improved propagation of charge carriers, remains a significant area of research.

Article Synopsis
  • The Six-Minute Walk Test (6MWT) is a cost-effective and quick assessment tool for evaluating physical function and quality of life in patients with chronic respiratory diseases.
  • A study conducted in northern India involving 110 patients highlighted the prevalence of conditions like chronic obstructive pulmonary disease and asthma while investigating the correlation between 6MWT results and spirometry measurements.
  • Results showed a significant positive relationship between the distance walked in the 6MWT and various spirometric parameters, suggesting that the 6MWT can reliably reflect pulmonary function in chronic respiratory disease patients.
