DFT investigation of 5-fluorouracil tautomerism and non-covalent interactions with PLGA nanoparticles for enhanced drug delivery and sensing.

This study investigates the non-covalent interactions between both the free and tautomeric forms of 5-fluorouracil (5-FU) and poly(lactic-co-glycolic acid) (PLGA) nanoparticles through density functional dispersion correction (DFT-D) at the B3LYP-D level in a dichloromethane (DCM) and water environments. Our results indicate that the non-covalent interactions formed between the carbonyl and amide groups of the free form of 5-FU and the carboxyl group of PLGA facilitate a rapid initial release of the drug, aligning with experimental findings. The calculated binding energies for 5-FU in its keto-enol (-0.

From protein to immunology: comprehensive insights into Marburg virus vaccines, mechanism, and application.

The Marburg virus (MARV), a member of the Filoviridae family, is a highly lethal pathogen that causes Marburg virus disease (MVD), a severe hemorrhagic fever with high fatality rates.Despite recurrent outbreaks, no licensed vaccine is currently available. This review explores MARV's genomic architecture, structural proteins, and recent advancements in vaccine development.

Enhancer zeste homolog 2 (EZH2) targeting by small interfering RNA (siRNA); recent advances and prospect.

Enhancer of zeste homolog 2 (EZH2) serves as the enzymatic catalytic subunit of the polycomb repressive complex 2 (PRC2), which is capable of modifying the expression of downstream target genes through the trimethylation of Lys-27 on histone 3 (H3K27me3). In addition to its role in H3K27me3 modification, EZH2 may influence gene expression through alternative mechanisms. The involvement of EZH2 in cellular processes such as proliferation, apoptosis, and senescence has been established.

Developing a highly sensitive electrochemical sensor for malathion detection based on green g-CN@LiCoO nanocomposites.

Nowadays, developing pesticide-free agriculture is highly demanded by society. The development of electrochemical sensors to monitor and control pesticides is an effective step toward this desired goal. The current research has faced this issue by modifying of glassy carbon electrodes (GCEs) with green g-CN@LiCoO nanocomposites to probe malathion, an organophosphate pesticide.

Pomegranate as a natural remedy for gastric ulcers prevention: a review of its gastroprotective mechanisms and pharmacological benefits.

Gastric ulcers (GUs) represent a common gastrointestinal disorder characterized by mucosal damage and inflammation, often precipitated by factors such as Helicobacter pylori infection and the consumption of COX inhibitors. This comprehensive review investigates the role of oxidative stress and inflammation in the pathogenesis of GUs and assesses the potential therapeutic effects of Punica granatum (pomegranate, Pg) supplementation. Utilizing a series of experimental models, including indomethacin, aspirin, and alcohol-induced ulcers, we demonstrate that Pg extracts possess significant gastroprotective properties.

Inflammasome activation in melanoma progression: the latest update concerning pathological role and therapeutic value.

The progression of melanoma is a complex process influenced by both internal and external cues which encourage the transition of tumour cells, uncontrolled growth, migration, and metastasis. Additionally, inflammation allows tumours to evade the immune system, contributing to cancer development. The inflammasome, a complex of many proteins, is crucial in enhancing immune responses to external and internal triggers.

The role of GATA4 in mesenchymal stem cell senescence: A new frontier in regenerative medicine.

The Mesenchymal Stem Cell (MSC) is a multipotent progenitor cell with known differentiation potential towards various cell lineage, making it an appealing candidate for regenerative medicine. One major contributing factor to age-related MSC dysfunction is cellular senescence, which is the hallmark of relatively irreversible growth arrest and changes in functional properties. GATA4, a zinc-finger transcription factor, emerges as a critical regulator in MSC biology.

Inflammatory signaling pathways in Alzheimer's disease: Mechanistic insights and possible therapeutic interventions.

The complex pathophysiology of Alzheimer's disease (AD) poses challenges for the development of therapies. Recently, neuroinflammation has been identified as a key pathogenic mechanism underlying AD, while inflammation has emerged as a possible target for the management and prevention of AD. Several prior studies have demonstrated that medications modulating neuroinflammation might lessen AD symptoms, mostly by controlling neuroinflammatory signaling pathways such as the NF-κB, MAPK, NLRP3, etc, and their respective signaling cascade.

Inhibitors of the mTOR signaling pathway can play an important role in breast cancer immunopathogenesis.

This study explores the critical role of inhibitors targeting the mammalian target of rapamycin (mTOR) signaling pathway in breast cancer research and treatment. The mTOR pathway, a central regulator of cellular processes, has been identified as a crucial factor in the development and progression of breast cancer. The essay explains the complex molecular mechanisms through which mTOR inhibitors, such as rapamycin and its analogs, exert their anticancer effects.

Emerging roles of long noncoding RNA H19 in human lung cancer.

Lung cancer holds the position of being the primary cause of cancer-related fatalities on a global scale. Furthermore, it exhibits the highest mortality rate among all types of cancer. The survival rate within a span of 5 years is less than 20%, primarily due to the fact that the disease is often diagnosed at an advanced stage, resulting in less effective treatment options compared to earlier stages.

Highlighting the role of long non-coding RNA (LncRNA) in multiple myeloma (MM) pathogenesis and response to therapy.

Transcripts longer than 200 nucleotides that are not translated into proteins are known as long non-coding RNAs, or lncRNAs. Now, they are becoming more significant as important regulators of gene expression, and as a result, of many biological processes in both healthy and pathological circumstances, such as blood malignancies. Through controlling alternative splicing, transcription, and translation at the post-transcriptional level, lncRNAs have an impact on the expression of genes.
