Direct and indirect modulation of STAT3/CSE/HS axis in triple negative breast cancer by non-coding RNAs: MALAT-1 lncRNA, miR-486-5p and miR-30a-5p.

Recently, our research group reported an upregulated expression profile of cystathionine γ-lyase (CSE) and cystathionine β-synthase (CBS), key enzymes involved in hydrogen sulfide (HS) production, in triple-negative breast cancer (TNBC) patients. However, the regulatory mechanisms underlying such altered expression patterns are not yet fully understood. In this study, we focused on the role of the STAT3/CSE/HS axis and the potential involvement of non-coding RNAs (ncRNAs), including long and short ncRNAs, in modulating this pivotal pathway.

The Inhibitory Potential of 2'-dihalo Ribonucleotides against HCV: Molecular Docking, Molecular Simulations, MM-BPSA, and DFT Studies.

Sofosbuvir is the first approved direct-acting antiviral (DAA) agent that inhibits the HCV NS5B polymerase, resulting in chain termination. The molecular models of the 2'-dihalo ribonucleotides used were based on experimental biological studies of HCV polymerase inhibitors. They were modeled within HCV GT1a and GT1b to understand the structure-activity relationship (SAR) and the binding interaction of the halogen atoms at the active site of NS5B polymerase using different computational approaches.

Paget-Schroetter syndrome: An unfamiliar cause of upper-limb deep venous thrombosis.

Paget-Schroetter syndrome (PSS), which is also called "effort thrombosis," is a venous variant of thoracic outlet syndrome. We report a rare case of upper-limb deep venous thrombosis (ULDVT) in a young patient who was later diagnosed as PSS. PSS is a rare cause of ULDVT, and it is usually seen in young adults who are involved in strenuous physical activity.

Fluoxetine hydrochloride loaded lipid polymer hybrid nanoparticles showed possible efficiency against SARS-CoV-2 infection.

Up to date, there were no approved drugs against coronavirus (COVID-19) disease that dangerously affects global health and the economy. Repurposing the existing drugs would be a promising approach for COVID-19 management. The antidepressant drugs, selective serotonin reuptake inhibitors (SSRIs) class, have antiviral, anti-inflammatory, and anticoagulant effects, which makes them auspicious drugs for COVID 19 treatment.

Investigating the Internalization and COVID-19 Antiviral Computational Analysis of Optimized Nanoscale Zinc Oxide.

Global trials are grappling toward identifying prosperous remediation against the ever-emerging and re-emerging pathogenic respiratory viruses. Battling coronavirus, as a model respiratory virus, via repurposing existing therapeutic agents could be a welcome move. Motivated by its well-demonstrated curative use in herpes simplex and influenza viruses, utilization of the nanoscale zinc oxide (ZnO) would be an auspicious approach.

MicroRNA-486-5p and microRNA-486-3p: Multifaceted pleiotropic mediators in oncological and non-oncological conditions.

Despite historically known as "junk" DNA, nowadays non-coding RNA transcripts (ncRNAs) are considered as fundamental players in various physiological and pathological conditions. Nonetheless, any alteration in their expression level has been reported to be directly associated with the incidence and aggressiveness of several diseases. MicroRNAs (miRNAs) are the well-studied members of the ncRNAs family.

Hybrid Fixation in Pediatric Forearm Fractures, does it Predispose to Non-union? A Case Report and Literature Review.

Introduction: Pediatric fracture non-union is rare, with limited published evidence available. Whilst there have been certain predisposing factors identified throughout case reports/series, we present a case, hypothesizing a previously undocumented risk factor for non-union.

Case Report: A 9-year-old boy sustained closed, diaphyseal both bone forearm fractures.

The MonteggiaFracture: literature review and report of a new variant.

Introduction: Giovanni Battista Monteggia first described the Monteggia fracture in 1814. The complexity of this injury was not fully appreciated until it was coined in English as a "Monteggia lesion" by Jose Luis Bado. The Bado classification divides Monteggia fractures into four types of true lesions, plus equivalent variants.

Development of a reversed phase liquid chromatographic method for analysis of pyridoxal-5'-phosphate and its impurities.

Since no proper method is available in literature for the analysis of pyridoxal-5'-phosphate, a reversed phase liquid chromatographic method was developed and validated for specificity, sensitivity, linearity, precision and accuracy. Nine potential related substances and forced degradation products could be successfully separated from the main peak. The separation was achieved on a Polaris C18 column (250 × 4.
