The intricate combination of organic and inorganic compounds found in snake venom includes proteins, peptides, lipids, carbohydrates, nucleotides, and metal ions. These components work together to immobilise and consume prey through processes such as paralysis and hypotension. Proteins, both enzymatic and non-enzymatic, form the primary components of the venom.

Sesbania grandiflora, a fast-growing shrub from the Fabaceae family, is extensively researched for its therapeutic properties. Despite its highly valued medicinal properties, there have been no reports on exploring the proteome of Sesbania grandiflora. The present study aims to address this gap by investigating the proteomic profile of Sesbania grandiflora seeds with a primary focus on identifying storage proteins.

Article Synopsis
  • The matrix metalloproteinases (MMPs) are zinc proteases that help break down components of the extracellular matrix (ECM) and are involved in processes like inflammation and cell growth.
  • A study of Drosophila MMPs Mmp1 and Mmp2 shows that while they are important for tissue remodeling, they are not necessary for embryonic development, and their localization (either membrane-anchored or released) is key in distinguishing their roles.
  • MMPs are categorized into secretory and membrane types based on their structure and function, and while humans have many MMPs, Drosophila only has two, highlighting the potential complexity of MMP regulation in disease progression.

  • Arsenic contamination in soil and water is a serious environmental problem, but bioremediation using plant growth-promoting bacteria offers a sustainable and cost-effective solution.
  • A study identified a specific bacterial isolate, ASBT-KP1, which has genes for resistance to heavy metals, promotes growth, and can accumulate significant amounts of arsenic.
  • When plants were grown with ASBT-KP1 in arsenic-free and arsenic-contaminated soils, their biomass increased by 13% and 37%, respectively, indicating its potential as a beneficial inoculant for agriculture.

A wax-patterned paper analytical device (µPAD) has been developed for point-of-care colourimetric testing of serum glutamic oxaloacetic transaminase (SGOT). The detection method was based on the transamination reaction of aspartate with α-ketoglutarate, leading to the formation of oxaloacetate which reacts with the reagent Fast Blue BB salt and forms a cavern pink colour. The intensity of the cavern pink colour grows as the concentration of SGOT increases.

Background: Snake venom is a complex mixture of organic and inorganic constituents, including proteins and peptides. Several studies showed that antivenom efficacy differs due to intra- and inter-species venom variation.

Methods: In the current study, comparative functional characterization of major enzymatic proteins present in Craspedocephalus malabaricus and Daboia russelii venom was investigated through various in vitro and immunological cross-reactivity assays.

Objectives: We sought to analyse the antibiotic susceptibility profiles and molecular epidemiology of MDR clinical isolates from South India using non-MDR isolates as a reference.

Methods: We established a comprehensive clinical strain library consisting of 58 isolates collected from patients across the South Indian state of Kerala from March 2017 to July 2019. The strains were subject to antibiotic susceptibility testing, modified carbapenem inactivation method assay for carbapenemase production, PCR sequencing, comparative sequence analysis and quantitative PCR of MDR determinants associated with antibiotic efflux pump systems, fluoroquinolone resistance and carbapenem resistance.

causes severe infections in humans, resists multiple antibiotics, and survives in stressful environmental conditions due to modulations of its complex transcriptional regulatory network (TRN). Unfortunately, our global understanding of the TRN in this emerging opportunistic pathogen is limited. Here, we apply independent component analysis, an unsupervised machine learning method, to a compendium of 139 RNA-seq data sets of three multidrug-resistant international clonal complex I strains (AB5075, AYE, and AB0057).

Article Synopsis
  • Wastewater malodour poses significant challenges to sanitation and health, primarily caused by volatile organic compounds like methanethiol, which is particularly concerning due to its strong odor and toxicity.
  • Traditional odor control methods are often too expensive or ineffective, leading researchers to explore bacteriophage-based solutions as a promising alternative.
  • The study highlights the use of two isolated phages, ɸPh_PP01 and ɸPh_PP02, which significantly reduced methanethiol production and bacteria levels in wastewater samples, demonstrating their potential as effective biocontrol agents for managing wastewater odor.

Zirconium copper oxide microflowers (Zr/CuO MF) based non-enzymatic sensor was developed for glucose detection in saliva, urine, and blood. An easy urea hydrolysis method was employed for the synthesis of the metal oxide and further calcined to improve the catalytic property. The flower-like morphology of the Zr/CuO was confirmed by SEM analysis and the presence of copper and zirconium was examined using energy dispersive X-ray analysis (EDAX).

Programmed cell death (PCD) is the universal process that maintains cellular homeostasis and regulates all living systems' development, health and disease. Out of all, apoptosis is one of the major PCDs that was found to play a crucial role in many disease conditions, including cancer. The cancer cells acquire the ability to escape apoptotic cell death, thereby increasing their resistance towards current therapies.

Over the last 34 months, at least 10 severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) distinct variants have evolved. Among these, some were more infectious while others were not. These variants may serve as candidates for identification of the signature sequences linked to infectivity and viral transgressions.

Introduction: Environmental enteropathy (EE), a chronic small intestine disease characterized by gut inflammation, is widely prevalent in low-income countries and is hypothesized to be caused by continuous exposure to fecal contamination. Targeted nutritional interventions using potential probiotic strains from fermented foods can be an effective strategy to inhibit enteric pathogens and prevent chronic gut inflammation.

Methods: We isolated potential strains from fermented rice water and lemon pickle and investigated their cell surface properties, antagonistic properties, adhesion to HT-29 cells, and inhibition of pathogen adherence to HT-29 cells.

The complexity of the antimicrobial resistance (AMR) crisis and its global impact on healthcare invokes an urgent need to understand the underlying forces and to conceive and implement innovative solutions. Beyond focusing on a traditional pathogen-centric approach to antibiotic discovery yielding diminishing returns, future therapeutic interventions can expand to focus more comprehensively on host-pathogen interactions. In this manner, increasing the resiliency of our innate immune system or attenuating the virulence mechanisms of the pathogens can be explored to improve therapeutic outcomes.

Glial cell line-derived neurotrophic factor (GDNF) signals through a multi-component receptor system predominantly consisting of glycosyl-phosphatidylinositol-anchored GDNF family receptor alpha-1 (GFRα1) and the Rearranged during transfection (RET) receptor tyrosine kinase. GDNF/RET signaling is vital to the central and peripheral nervous system, kidney morphogenesis, and spermatogenesis. In addition, the dysregulation of the GDNF/RET signaling has been implicated in the pathogenesis of cancers.
