Dicer inhibition delays wound closure by increasing SUZ12 levels and regulating ITGAV levels in keratinocytes.

Delayed wound closure is a significant hallmark associated with diabetes. A previous study from our laboratory identified decreased levels of Dicer and miRNAs together with altered levels of wound healing genes in the wounded tissues of diabetic rats. Comprehensive regulators of these wound healing genes mapped onto the PRC2 (polycomb repressive complex 2) complex.

Framework for site specific leachate limits in MSW dumpsites: Integration of high-resolution site characterization and contaminant transport modeling.

The establishment of site-specific target limits (SSTLs) for old municipal solid waste (MSW) dumpsites is essential for defining remediation goals in a scientifically rigorous manner. However, a standardized framework for achieving this is currently lacking. This study proposes a comprehensive framework that integrates high-resolution site characterization (HRSC) tools, targeted sampling, and contaminant transport modeling to derive SSTLs.

Effectiveness of the primary Bacillus Calmette-Guérin vaccine against the risk of Mycobacterium tuberculosis infection and tuberculosis disease: a meta-analysis of individual participant data.

Background: Tuberculosis vaccine trials using disease as the primary endpoint are large, time consuming, and expensive. An earlier immunological measure of the protection against disease would accelerate tuberculosis vaccine development. We aimed to assess whether the effectiveness of the Bacillus Calmette-Guérin (BCG) vaccine for prevention of Mycobacterium tuberculosis infection was consistent with that for prevention of tuberculosis disease.

Solid stress estimations via intraoperative 3D navigation in patients with brain tumors.

Background: Physical forces exerted by expanding brain tumors - specifically the compressive stresses propagated through solid tissue structures - reduces brain perfusion and neurological function, but heretofore has not been directly measured in patients . Solid stress levels estimated from tumor growth patterns are negatively correlated with neurological performance in patients. We hypothesize that measurements of solid stress can be used to inform clinical management of brain tumors.

Novel selective and sensitive electrochemical sensor for detection of ovarian cancer biomarker, Cathepsin L.

Late detection of ovarian cancer is critical as it results in decreased life expectancy of patients. Screening methodology with a rapid turnover is required to ensure better patient outcomes. Till date, no point of care diagnostics exists capable of monitoring epithelial ovarian cancer.

Advanced characterisation of groundwater contamination at a dumpsite: Methodology and assessment - Case study of a municipal solid waste dumpsite in India.

Groundwater (GW) contamination due to municipal solid waste (MSW) disposal in open dumpsites is a pressing global issue. Traditional GW assessment studies are limited to single-depth sampling from nearby wells/handpumps, providing limited insights into subsurface soil characteristics and are prone to cross-contamination. The present study introduces an innovative methodology integrating advanced techniques: Cone Penetration Testing (CPT), Hydraulic Profiling Tool (HPT), Continuous Soil Sampling, and Discrete GW Sampling.

Microplastic migration from landfill-mined soil through earth filling operations and ecological risk assessment: a case study in New Delhi, India.

Microplastics (MPs), plastic pieces smaller than 5 mm, are emerging as a critical ecological threat, potentially disrupting ecosystems and complicating waste management practices. Landfill-Mined Soil-Like Material (LMSLM), a byproduct of landfill reclamation, is gaining global traction for rehabilitating degraded land and repurposing it for geotechnical applications. While studies have examined contaminants like heavy metals and salts, MPs contamination has been largely overlooked, raising environmental concerns.

Utility of icobrain for brain volumetry in multiple sclerosis clinical practice.

Background: Few studies on multiple sclerosis (MS) have explored the variability of percentage brain volume change (PBVC) measurements obtained from different clinical MRIs. In a retrospective multicentre cohort study, we quantified the variability of annualised PBVC in clinical MRIs.

Methods: Clinical MRIs of relapse-onset MS patients were assessed by icobrain.

Immunization Status, Immunization Coverage, and Factors Associated with Immunization Service Utilization Among HIV-Exposed and HIV-Infected Children in India.

Background And Objective: HIV-infected and HIV-exposed children are known to have a lower immunization coverage. However, the current immunization coverage for this group of children in India is unknown. The present study assessed the immunization status, service-utilization issues, and factors associated with immunization status among them.

Lability in parent-child warmth and hostility and adolescent externalizing behaviors.

Both longer term developmental changes (increases in hostility, decreases in warmth) and lability (year-to-year fluctuations) in parent-child relationship quality across childhood and adolescence have been linked to adolescent externalizing behaviors. Using a prospective longitudinal study of 561 children who were adopted into nonrelative families at birth (57% male, 56% White, 19% multiracial, 13% Black, 11% Hispanic) where parental warmth and hostility reflect environmental influences or child-evoked reactions, we examined associations between parent-child relationship measures and externalizing behaviors at age 11 and across adolescence (i.e.

Light-Controlled Anticancer Activity and Cellular Uptake of a Photoswitchable Cisplatin Analogue.

A photoactive analogue of cisplatin was synthesized with two arylazopyrazole ligands, able to undergo -/- photoisomerizations. The photoisomer showed a dark half-life of 9 days. The cytotoxicities of both photoisomers of the complex were determined in several cancer and normal cell lines and compared to that of cisplatin.

An Ultrahigh Affinity DNA Aptamer for Quinine and Its Intrinsic Fluorescence Based Label-Free Detection.

Measuring quinine is critical for the detection of its overdose, understanding its pharmacological and toxicological effects, and monitoring its pollution. While a previously reported aptamer named MN4 can bind quinine, it was not selected for it, leading to compromised binding affinity and specificity. In this work, a new quinine aptamer was isolated using the library immobilization capture-SELEX technique.

Vitamin D and Neurological Health: Unraveling Risk Factors, Disease Progression, and Treatment Potential.

This study explores the complex link between vitamin D and neurological illnesses, focusing on how vitamin D affects possible risk factors, therapeutic applications, and the trajectory of the disease. An epidemiological study has linked vitamin D insufficiency to several neurological conditions, including Parkinson's disease, Alzheimer's disease, and multiple sclerosis. It is hypothesized that immunomodulatory and anti-inflammatory properties of vitamin D contribute to its neuroprotective effects.

Homoeopathy vs. conventional primary care in children during the first 24 months of life-a pragmatic randomised controlled trial.

Unlabelled: To compare the difference between primary homoeopathic and conventional paediatric care in treating acute illnesses in children in their first 24 months of life. One hundred eight Indian singleton newborns delivered at 37 to 42 weeks gestation were randomised at birth (1:1) to receive either homoeopathic or conventional primary care for any acute illness over the study period. In the homoeopathic group, conventional medical treatment was added when medically indicated.

A Mem-dELISA platform for dual color and ultrasensitive digital detection of colocalized proteins on extracellular vesicles.

Accurate, multiplex, and ultrasensitive measurement of different colocalized protein markers on individual tumor-derived extracellular vesicles (EVs) and dimerized proteins with multiple epitopes could provide insights into cancer heterogeneity, therapy management and early diagnostics that cannot be extracted from bulk methods. However, current digital protein assays lack certain features to enable robust colocalization, including multi-color detection capability, large dynamic range, and selectivity against background proteins. Here, we report a lithography-free, inexpensive (< $0.

Insight into the Course of the Ferrier Rearrangement Used to Obtain Untypical Diosgenyl Saponins.

The Ferrier rearrangement was utilized to obtain 2,3-unsaturated diosgenyl glycosides. This reaction proceeded with high stereoselectivity, yielding mostly saponins with an α configuration (hexoses) or predominantly with a β configuration (pentoses). The diversity of the glycals used and the glycosides obtained enabled a deep discussion of the Ferrier rearrangement mechanism.

Intergenerational transmission of comorbid internalizing and externalizing psychopathology at age 11: Evidence from an adoption design for general transmission of comorbidity rather than homotypic transmission.

Psychopathology is intergenerationally transmitted through both genetic and environmental mechanisms via heterotypic (cross-domain), homotypic (domain-specific), and general (e.g., "p-factor") pathways.

Simulating the impact of tumor mechanical forces on glymphatic networks in the brain parenchyma.

The brain glymphatic system is currently being explored in the context of many neurological disorders and diseases, including traumatic brain injury, Alzheimer's disease, and ischemic stroke. However, little is known about the impact of brain tumors on glymphatic function. Mechanical forces generated during tumor development and growth may be responsible for compromised glymphatic transport pathways, reducing waste clearance and cerebrospinal fluid (CSF) transport in the brain parenchyma.

Introduction Healthcare systems around the world were disrupted by the COVID-19 pandemic. Multiple waves were experienced by most countries, and clinical symptoms and severity varied between these waves. A COVID-19 infection in pregnant women may result in complications for both the mother and the fetus and thus pose an additional challenge for clinicians.

A DNA Aptamer for 2-Aminopurine: Binding-Induced Fluorescence Quenching.

2-Aminopurine (2AP) is a fluorescent analog of adenine, and its unique properties make it valuable in various biochemical and biotechnological applications. Its fluorescence property probes local dynamics in DNA and RNA because stacking with the surrounding bases quench its fluorescence. 2AP-labeled DNA or RNA sequences have been used for the detection of genetic mutations, viral RNA, or other nucleic acid-based markers associated with diseases like cancer and infectious diseases.

Low-cost and scalable projected light-sheet microscopy for the high-resolution imaging of cleared tissue and living samples.

Light-sheet fluorescence microscopy (LSFM) is a widely used technique for imaging cleared tissue and living samples. However, high-performance LSFM systems are typically expensive and not easily scalable. Here we introduce a low-cost, scalable and versatile LSFM framework, which we named 'projected light-sheet microscopy' (pLSM), with high imaging performance and small device and computational footprints.
