SARS-CoV-2 pathophysiology and post-vaccination severity: a systematic review.

Currently, COVID-19 is still striking after 4 years of prevalence, with millions of cases and thousands of fatalities being recorded every month. The virus can impact other major organ systems, including the gastrointestinal tract (GIT), cardiovascular, central nervous system, renal, and hepatobiliary systems. The resulting organ dysfunction from SARS-CoV-2 may be attributed to one or a combination of mechanisms, such as direct viral toxicity, disruptions in the renin-angiotensin-aldosterone system (RAAS), thrombosis, immune dysregulation, and ischemic injury due to vasculitis.

Effects of antibiotic supplementation vs. nutrient stress on α-linolenic acid and α-tocopherol in Scenedesmus sp.

The hormetic effects of antibiotics on Scenedesmus sp. werecompared with nitrogen limitationstrategies. We observed that 100 and 1000 nM supplementation with antibiotics could stimulate bothα-linolenic acid (ALA) and α-tocopherol productivities.

Metabolomics in Context of Alpha-Ketoglutarate and Lactate in Neonates with Birth Asphyxia.

Background: Neonatal birth/perinatal asphyxia is a critical condition that can adversely affect many different bodily tissues, particularly the brain; depending on duration and severity of asphyxia, leading to difficulties and lifelong disabilities. These can be avoided by early detection of the biochemical derangements and prompt intervention. Serum alpha-ketoglutarate (α-KG) and cord blood lactate have been found to be associated with birth asphyxia and may have potential to act as biomarkers for birth asphyxia.

Exploring the role of HIF-1α on pathogenesis in Alzheimer's disease and potential therapeutic approaches.

Hypoxia-inducible factor 1α (HIF-1α) is a crucial transcription factor that regulates cellular responses to low oxygen levels (hypoxia). In Alzheimer's disease (AD), emerging evidence suggests a significant involvement of HIF-1α in disease pathogenesis. AD is characterized by the accumulation of amyloid-beta (Aβ) plaques and neurofibrillary tangles (NFTs), leading to neuronal dysfunction and cognitive decline.

Recent Trends in Seroprevalence of Celiac Disease at a Tertiary Care Center.

It is a retrospective study and all samples received in the laboratory from symptomatic patients for estimation of Immunoglobulin A (IgA) antitissue transglutaminase (IgA anti-tTGA) antibodies are included. Seroprevalence of celiac disease was determined using indirect enzyme-linked immunosorbent assay for IgA anti-tTGA. Out of 8787 serum samples received in the laboratory over a period of four years, the seroprevalence of CD was 2.

Emerging roles of cannabinoid receptor CB2 receptor in the central nervous system: therapeutic target for CNS disorders.

Rationale: The endocannabinoid system (ECS) belongs to the G protein-coupled receptor family of cell membranes and is associated with neuropsychiatric conditions, and neurodegenerative diseases. Cannabinoid 2 receptors (CB2) are expressed in the central nervous system (CNS) on microglia and subgroups of neurons and are involved in various behavioural processes via immunological and neural regulation.

Objective: The objective of this paper is to summarize and explore the impact of CB2 receptors on neuronal modulation, their involvement in various neurological disorders, and their influence on mood, behavior, and cognitive function.

CTAB-crafted ZnO nanostructures for environmental remediation and pathogen control.

This study addresses the critical need for efficient and sustainable methods to tackle organic pollutants and microbial contamination in water. The present work aim was to investigate the potential of multi-structured zinc oxide nanoparticles (ZnO NPs) for the combined photocatalytic degradation of organic pollutants and antimicrobial activity. A unique fusion of precipitation-cum-hydrothermal approaches was precisely employed to synthesize the ZnO NPs, resulting in remarkable outcomes.

The burden of tuberculosis among patients with non-small cell lung carcinoma in a tertiary care center.

Background: Lung cancer and tuberculosis share similar risk factors, clinical spectrum, radiological features and it is difficult to differentiate but it is important to diagnose both conditions for targeted therapy and better outcome.

Aims: Our primary objective was to estimate the proportion of TB in primary biopsy proven non-small cell lung carcinoma (NSCLC) cases.

Material & Methods: This prospective observational study was conducted in the Departments of Medicine/Pulmonary Medicine/Medical Oncology and Microbiology at the All India Institute of Medical Sciences, New Delhi for a period of 2 years (January 2020-December 2021).

Proton Therapy in The Treatment of Head And Neck Cancers- Review.

Purpose Of Review: Head and neck cancers rank as the seventh most common cancer worldwide, nearly half of which result in death. The most common treatment methods for head and neck cancers include radiotherapy and surgery. Proton therapy has emerged in radiotherapy for cases where tumors are located near anatomically sensitive areas where the radiation dose must be strictly limited.

Exploring the potential of graphite material in an unplanted electroactive wetland for the remediation of synthetic wastewater containing azo dye.

The current study was conducted to understand the sole role of graphite as a substrate material in a dual-chambered baffled electroactive wetland (EW) in the treatment of Methyl red dye-containing wastewater.
