Purpose: Biliary atresia (BA) is a critical pediatric condition requiring timely intervention through Kasai portoenterostomy (KPE), and up to two-thirds of patients need liver transplantation (LT). The outcomes for BA patients still need improvement in low- and middle-income countries. This study aims to assess the socioeconomic and geographical profile of BA patients in India, focusing on their compliance with follow-up care, treatment-seeking behaviour, and acceptability of LT in addition, it provides recommendations to overcome identified challenges.

Water clusters containing Na and Cl ions play a key role in the atmospheric chemistry of sea salt aerosols. While Na is clearly buried deep inside, Cl appears to be a chameleon since evidence for both surface-localized and interior solvation states are reported. Thus, disclosing the preferred location of Cl within clusters remains challenging.

Pre-exposure prophylaxis (PrEP) has emerged as a prominent approach for the prevention of HIV infections. While the latest advances have resulted in effective oral and injectable product options, there are still gaps in on-demand, event-driven, topical products for HIV prevention that are safe and effective. Here we describe the formulation development of a dual-compartment topical insert containing tenofovir alafenamide fumarate (TAF) and elvitegravir (EVG) that may be administered when needed, vaginally or rectally, pre- or post-coitus, for flexible HIV prophylaxis.

Methotrexate (MTX) is an antimetabolite drug that mimics folate and inhibits dihydrofolic acid reductase, resulting in the impairment of malignant growth in actively proliferating tissues. MTX is approved by the FDA for primarily treating non-Hodgkin lymphoma, lymphoblastic leukemia, and osteosarcoma. In addition, MTX is also prescribed as a preferred anti-rheumatic medication for the management of rheumatoid arthritis, including psoriasis, indicating that MTX has a multipronged mechanism of action.

3D printing has emerged as a highly efficient process for fabricating electrodes in hydrogen evolution through water splitting, whereas metals are the most popular choice of materials in hydrogen evolution reactions (HER) due to their catalytic activity. However, current 3D printing solutions face challenges, including high cost, low surface area, and sub-optimal performance. In this work, we introduce metal-deposited 3D printed pyrolytic carbon (PyC) as a facile and cost-effective HER electrode.

The rising soil-groundwater quality issues due to pharmaceuticals and personal care products (PPCPs) contamination have spurred significant concern. To understand the sorption characteristics of metformin (MTN) and erythromycin (ETM) in sandy and sandy loam soils with varying organic matter and particle composition, sorption kinetics (single and competitive), isotherms, and thermodynamics were studied. The effects of pH and soil moisture content (SMC) were also investigated at environmentally relevant concentrations.

Host-directed therapies (HDT) via modulation of specific host responses like inflammation can limit mycobacterial infection. HDTs could be included in current TB therapy as an adjunct to increase bacterial clearance and limit tissue damage to control spread. Individually, Mycobacterium indicus pranii (MIP) and human beta defensin-2 (hBD-2) are promising therapies for tuberculosis (TB).

Multi-drug resistance in bacteria is emerging as a major global health challenge, causing substantial harm in terms of mortality, morbidity, and financial strain on healthcare systems. These bacteria are constantly acquiring new virulence factors and drug-resistance mechanisms, which highlights the critical need for innovative antimicrobial medicines and identification of new therapeutic targets, such as Sortase A (EfSrtA). EfSrtA, a transpeptidase significant for the adhesion and virulence of Enterococcus faecalis (E.

Article Synopsis
  • Proximal tibial fractures, especially those impacting the tibial plateau, require careful treatment to regain knee function and reduce long-term disability, with new variable-angle locking compression plates (VALCP) showing promise against conventional locking plates (CLCP).
  • A study conducted from January 2020 to August 2021 evaluated outcomes for 60 patients with Schatzker's type I, II, and III fractures, dividing them into two groups to compare the effectiveness of CLCP versus VALCP using various grading systems for clinical and functional assessments.
  • Results indicated that the majority of injuries were due to road traffic accidents, with a higher age average in the CLCP group compared to the VALCP group, highlighting the need for further analysis on

  • Chronic Limb Threatening Ischemia (CLTI) is a severe condition leading to high rates of limb amputation and cardiovascular death, particularly in cases where standard treatments fail.
  • Endovascular interventions are the main treatment strategy, but a significant number of patients are considered "no-option," prompting interest in new therapies like bone marrow-derived mesenchymal stromal cells (BM-MSC).
  • REGENACIP is an approved BM-MSC therapy in India for patients with critical limb ischemia who are not candidates for traditional revascularization, and this review discusses its potential benefits and effectiveness in treating CLTI.

Background: Sulphotransferase (SOT) enzyme (encoded by a conserved family of SOT genes) is involved in sulphonation of a variety of compounds, through transfer of a sulphuryl moiety from 3'phosphoadenosine- 5'phosphosulphate (PAPS) to a variety of secondary metabolites. The PAPS itself is derived from 3'adenosine-5'phosphosulphate (APS) that is formed after uptake of sulphate ions from the soil. The process provides tolerance against abiotic stresses like drought and heat in plants.

The cross-species transmissibility of SARS-CoV-2 infection has necessitated development of specific reagents for detecting infection in various animal species. The spike glycoprotein of SARS-CoV-2, which is involved in viral entry, is a highly immunogenic protein. To develop assays targeting this protein, we generated eight monoclonal antibodies (mAbs) against the S1 and seven against the S1/S2 protein (ectodomain) of SARS CoV-2.

Dry eye disease (DED) is a common, multifactorial ocular disease impacting 5% to 20% of people in Western countries and 45% to 70% in Asian countries. Despite the prevalence of DED and the number of treatment approaches available, signs and symptoms of the disease continue to limit the quality of life for many patients. Standard over-the-counter treatment approaches and behavior/environmental modifications may help some cases but more persistent forms often require pharmacological interventions.

Inhibitors of kinases involved in signaling and other intracellular pathways, have revolutionized cancer treatment by providing highly targeted and effective therapies. However, timely monitoring treatment response remains a considerable challenge since conventional methods such as assessing changes in tumor volume do not adequately capture early responses or resistance development, due to the predominantly cytostatic rather than cytotoxic effect of kinase inhibitors. Magnetic resonance spectroscopy (MRS) is a non-invasive imaging technique that can provide insights into cellular metabolism by detecting changes in metabolite concentrations.
