Assembling branched and macrocyclic peptides on proteins.

A two-step, biocompatible strategy enables site-specific generation of branched and macrocyclic peptide-protein conjugates. Solvent-exposed cysteines on proteins are modified by a small bifunctional reagent at near-physiological pH, followed by cyanopyridine-aminothiol click reactions to create branched or macrocyclic peptide architectures. This method offers design strategies for next-generation protein therapeutics.

Background: Addressing oculoplastic conditions in the preoperative period ensures both the safety and functional success of any ophthalmic procedure. Some oculoplastic conditions, like nasolacrimal duct obstruction, have been extensively studied, whereas others, like eyelid malposition and thyroid eye disease, have received minimal or no research.

Aim: To investigate the current practice patterns among ophthalmologists while treating concomitant oculoplastic conditions before any subspecialty ophthalmic intervention.

Inhibition of peptidyl arginine deiminase-4 ameliorated pulmonary fibrosis via modulating M1/M2 polarisation of macrophages.

Pulmonary fibrosis (PF) arises from dysregulated wound healing, leading to excessive extracellular matrix (ECM) deposition and impaired lung function. Macrophages exhibit high plasticity, polarizing to pro-inflammatory M1 during early inflammation and anti-inflammatory, fibrosis-inducing M2 during later stages of PF. Additionally, neutrophils and neutrophil extracellular traps (NETs) release mediated by peptidyl arginine deiminase (PAD-4), also play a key role in PF progression.

7-Hydroxy-3-(4'-methoxyphenyl) coumarin (C12) attenuates bleomycin-induced acute lung injury and fibrosis through activation of SIRT3.

Silent mating-type information regulation 2 homology 3 (SIRT3) is a member of the sirtuins family expressed in mitochondria performs deacetylation of metabolic enzymes and promotes longevity. 7-hydroxy-3-(4'-methoxyphenyl) coumarin (C12) is a small molecule first ever known for its direct activation of SIRT3. SIRT3 performs its function by balancing the redox system by activating manganese superoxide dismutase (MnSOD) and 8-Oxoguanine glycosylase (OGG1).

Exploring Radiology Postgraduate Students' Engagement with Large Language Models for Educational Purposes: A Study of Knowledge, Attitudes, and Practices.

 The integration of large language models (LLMs) into medical education has received increasing attention as a potential tool to enhance learning experiences. However, there remains a need to explore radiology postgraduate students' engagement with LLMs and their perceptions of their utility in medical education. Hence, we conducted this study to investigate radiology postgraduate students' knowledge, attitudes, and practices regarding LLMs in medical education.

Effect of antiepileptic drug monotherapy on endogenous sex hormonal profile in men and women with epilepsy.

Objective: To assess the alterations of endogenous sex hormone profiles in patients with epilepsy (PWE) on different antiepileptic drug (AED) monotherapies compared to healthy controls and drug naïve PWE (DNPWE).

Methods: Four databases MEDLINE, EMBASE, SCOPUS, and CENTRAL were searched for analytical observational/intervention studies on the assessment of endogenous sex hormones in PWE compared to healthy controls and DNPWE. Two researchers reviewed the title/abstract, and full-text articles for the selection of the studies independently.

Enhancing residency training by addressing anatomical knowledge gaps through structured educational programs: a need assessment study in radio diagnosis residents.

Introduction: The evolving curricula in medical education have significantly reduced the time allocated for learning and clinically correlating anatomical facts. This has led to noticeable gaps in the anatomical knowledge observed by specialists while training junior residents and is being extensively documented in the literature.

Materials And Methods: The descriptive, cross-sectional, questionnaire-based study was conducted online by sharing the questionnaire via e-mail, WhatsApp, and Telegram to institutes across all Indian states and union territories where postgraduate radiodiagnosis courses are offered.

Non-symmetric cysteine stapling in native peptides and proteins.

Stapling rigidifies peptides through covalent linkages between amino acids. We introduce 2-chloromethyl-6-cyanopyridine for non-symmetric stapling of N-terminal and internal cysteines. This biocompatible method produces diverse peptide macrocycles with enhanced affinity, stability and inhibitory potency.

Etiological spectrum of acute kidney injury and adverse outcome: A single-center observation.

Background: The present study aims to evaluate the etiological spectrum with clinicopathological parameters and adverse outcomes of acute kidney injury (AKI).

Methods: A hospital-based prospective observational study was conducted for a spectrum of AKI in 103 AKI patients and their AKI-associated adverse outcomes. The AKI patients were included as per the KDIGO definition.

Diagnostic performance of artificial intelligence in detecting oral potentially malignant disorders and oral cancer using medical diagnostic imaging: a systematic review and meta-analysis.

Objective: Oral cancer is a widespread global health problem characterised by high mortality rates, wherein early detection is critical for better survival outcomes and quality of life. While visual examination is the primary method for detecting oral cancer, it may not be practical in remote areas. AI algorithms have shown some promise in detecting cancer from medical images, but their effectiveness in oral cancer detection remains Naïve.

RT-PCR Result of SARS-CoV-2 Viral RNA in Cadavers and Viral Transmission Risk to Handlers.

Unlabelled: During the onset of the pandemic, a common research question was asked by the hospital staff, and family members who were handling COVID-19-infected cadavers, "does COVID-19-positive dead body harbor SARS-CoV-2 viral RNA?" Several research findings were reported but due to the lack of proper research findings, the question remained unanswered. The present study was planned to observe the virus transmission risk from cadavers to the handlers. A pilot study was conducted on 54 cadavers who died in COVID-ICU (SARS-CoV-2-positive diagnosed by RT-PCR) during 2021-2022.

Fruit-In-Sight: A deep learning-based framework for secondary metabolite class prediction using fruit and leaf images.

Fruits produce a wide variety of secondary metabolites of great economic value. Analytical measurement of the metabolites is tedious, time-consuming, and expensive. Additionally, metabolite concentrations vary greatly from tree to tree, making it difficult to choose trees for fruit collection.

Peptidyl arginine deiminase-4 inhibitor ameliorates pulmonary fibrosis through positive regulation of developmental endothelial locus-1.

Recurring lung injury, chronic inflammation, aberrant tissue repair and impaired tissue remodelling contribute to the pathogenesis of pulmonary fibrosis (PF). Neutrophil extracellular traps (NETs) are released by activated neutrophils to trap, immobilise and kill invading pathogen and is facilitated by peptidyl arginine deiminase-4 (PAD-4). Dysregulated NETs release and abnormal PAD-4 activation plays a crucial role in activating pro-fibrotic events in PF.
