The present study sought to elucidate the prevalence of vitamin D deficiency in infants and its potential association with various anthropometric and hematological parameters.

Methods: The study was conducted in a tertiary care hospital in northern India (in 2013-14) and involved 77 nine-month-old infants.

Nanoformulated fisetin ameliorates Alzheimer's disease via reducing proinflammatory cytokines and activating the NRF2/HO-1 pathway.

The study aimed to evaluate the neuroprotective effect of a chitosan-coated fisetin nanoformulation in an experimental Alzheimer's disease (AD) model, focusing on improving fisetin's pharmacokinetics and exploring its impact on both brain and colon pathology. AD was induced in mice by intracerebroventricular administration of Aβ. Mice were treated with either fisetin or a fisetin nanoformulation (5 mg/kg/day, orally) for 21 days.

Host defense peptides at the crossroad of endothelial cell physiology: Insight into mechanistic and pharmacological implications.

Antimicrobial peptides (AMPs), particularly host defense peptides (HDPs), have gained recognition for their role in host defense mechanisms, but they have also shown potential as a promising anticancer, antiviral, antiparasitic, antifungal and immunomodulatory agent. Research studies in recent years have shown HDPs play a crucial role in endothelial cell function and biology. The function of endothelial cells is impacted by HDPs' complex interplay between cytoprotective and cytotoxic actions as they are known to modulate barrier integrity, inflammatory response and angiogenesis.

Unraveling the Regulatory Role of HuR/microRNA Axis in Colorectal Cancer Tumorigenesis.

Colorectal cancer (CRC) remains a significant global health burden with high incidence and mortality. MicroRNAs (miRNAs) are small non-protein coding transcripts, conserved throughout evolution, with an important role in CRC tumorigenesis, and are either upregulated or downregulated in various cancers. RNA-binding proteins (RBPs) are known as essential regulators of miRNA activity.

Concomitant Boost With Six Fractions of Radiation a Week in Locally Advanced Head and Neck Cancer Patients: A Prospective Study.

Background and objective Radiation therapy plays a significant role in the radical treatment of locally advanced head and neck cancers. Studies have shown the radiobiological advantage of accelerated chemoradiation over conventional chemoradiation as it reduces the chances of accelerated repopulation and decreases overall treatment time. This study aimed to assess the response and toxicities of accelerated concomitant chemoradiation in locally advanced head and neck cancer patients.

Intricate relationship between cancer stemness, metastasis, and drug resistance.

Cancer stem cells (CSCs) are widely acknowledged as the drivers of tumor initiation, epithelial-mesenchymal transition (EMT) progression, and metastasis. Originating from both hematologic and solid malignancies, CSCs exhibit quiescence, pluripotency, and self-renewal akin to normal stem cells, thus orchestrating tumor heterogeneity and growth. Through a dynamic interplay with the tumor microenvironment (TME) and intricate signaling cascades, CSCs undergo transitions from differentiated cancer cells, culminating in therapy resistance and disease recurrence.

Identification of pivotal genes and pathways in Chorea-acanthocytosis using comprehensive bioinformatic analysis.

Chorea-acanthocytosis (ChAc), an autosomal recessive disorder, is associated with cognitive and behavioral abnormalities. Previous studies were focused around exploring the functional annotation of VPS13A gene in ChAc, whereas the genetic labyrinth underlying this disease and plausible drug targets were underexplored. In the present study, we have identified the pivotal genes and molecular pathways implicated in ChAc using comprehensive bioinformatics analysis.

Distinct evolutionary trajectories following loss of RNA interference in .

While increased mutation rates typically have negative consequences in multicellular organisms, hypermutation can be advantageous for microbes adapting to the environment. Previously, we identified two hypermutator clinical isolates that rapidly develop drug resistance due to transposition of a retrotransposon, Cnl1. Cnl1-mediated hypermutation is caused by a nonsense mutation in the gene encoding a novel RNAi component, Znf3, combined with a tremendous transposon burden.

Role of ursolic acid in preventing gastrointestinal cancer: recent trends and future perspectives.

Gastrointestinal malignancies are one of the major worldwide health concerns. In the present review, we have assessed the plausible therapeutic implication of Ursolic Acid (UA) against gastrointestinal cancer. By modulating several signaling pathways critical in cancer development, UA could offer anti-inflammatory, anti-proliferative, and anti-metastatic properties.

Short-term S100A8/A9 Blockade Promotes Cardiac Neovascularization after Myocardial Infarction.

Acute-phase inhibition of the pro-inflammatory alarmin S100A8/A9 improves cardiac function post-myocardial infarction (MI), but the mechanisms underlying the long-term benefits of this short-term treatment remain to be elucidated. Here, we assessed the effects of S100A8/A9 blockade with the small-molecule inhibitor ABR-238901 on myocardial neovascularization in mice with induced MI. The treatment significantly reduced S100A9 and increased neovascularization in the myocardium, assessed by CD31 staining.

Advancements and recent explorations of anti-cancer activity of chrysin: from molecular targets to therapeutic perspective.

In recent times, there have been notable advancements in comprehending the potential anti-cancer effects of chrysin (CH), a naturally occurring flavonoid compound found abundantly in various plant sources like honey, propolis, and certain fruits and vegetables. This active compound has garnered significant attention due to its promising therapeutic qualities and minimal toxicity. CH's ability to combat cancer arises from its multifaceted mechanisms of action, including the initiation of apoptosis and the inhibition of proliferation, angiogenesis, metastasis, and cell cycle progression.

Life cycle assessment of chemically treated and copper coated sustainable biocomposites.

The current demand for composites reinforced with renewable fibers is greater than it has ever been. In comparison to glass fibers, natural fibers yield the advantages of lesser density and cost. Although comparable specific properties exist between glass and natural fibers, the latter shows lower strength.

Unraveling the Triad: Hypoxia, Oxidative Stress and Inflammation in Neurodegenerative Disorders.

The mammalian brain's complete dependence on oxygen for ATP production makes it highly susceptible to hypoxia, at high altitudes or in clinical scenarios including anemia or pulmonary disease. Hypoxia plays a crucial role in the development of various brain disorders, such as Alzheimer's, Parkinson's, and other age-related neurodegenerative diseases. On the other hand, a decrease in environmental oxygen levels, such as prolonged stays at high elevations, may have beneficial impacts on the process of ageing and the likelihood of death.

Applications of Surface Plasmon Resonance (SPR) to the Study of Diverse Protein-Ligand Interactions.

Functional characterization of enzymes/proteins requires determination of the binding affinity of small molecules or other biomolecules with the target proteins. Several available techniques, such as proteomics and drug discovery strategies, require a precise and high-throughput assay for rapid and reliable screening of potential candidates for further testing. Surface plasmon resonance (SPR), a well-established label-free technique, directly measures biomolecular affinities.

Anxiety, stress, and quality of life in patients with tuberculosis: A systematic review and meta-analysis.

Anxiety symptoms when coexisting with tuberculosis (TB), can have deleterious effects on treatment continuation that could contribute to the development of treatment resistance in TB. It is essential to understand the prevalence of anxiety in TB to develop clinical recommendations for its management. The primary objective of our review was to estimate the pooled prevalence of anxiety in TB patients along with the estimation of stress and quality of life in such patients.

Oncogenes and tumor suppressor genes: functions and roles in cancers.

Cancer, being the most formidable ailment, has had a profound impact on the human health. The disease is primarily associated with genetic mutations that impact oncogenes and tumor suppressor genes (TSGs). Recently, growing evidence have shown that X-linked TSGs have specific role in cancer progression and metastasis as well.
