Background And Objective: Insulin resistance is a primary feature of type 2 diabetes. This study compared the effects of curcumin and its nanoformulation on insulin resistance, fasting blood sugar, liver function, GLUT4, lipid profile, and oxidative stress in the liver and pancreas in a diabetic model.

Methods: Thirty male Wistar rats were divided into five groups: a control group, a diabetic group, a diabetic group treated with metformin (40 mg/kg), a diabetic group treated with curcumin (100 mg/kg), and a diabetic group treated with curcumin NPs (100 mg/kg).

Article Synopsis
  • The study focused on elderly patients (70+) undergoing primary percutaneous coronary intervention (pPCI) for ST-elevation myocardial infarction (STEMI) at a tertiary center in Upper Egypt, highlighting a growing concern for cardiovascular disease in aging populations.
  • The research included data from 3,627 patients, finding that 15.9% were elderly, with significantly higher in-hospital mortality rates, particularly among octogenarians (23.3%) compared to younger patients (4%).
  • Elderly patients showed distinct clinical characteristics, such as higher rates of hypertension and chronic kidney disease, and were more likely to have severe complications post-procedure, emphasizing the need for tailored strategies in managing this demographic in cardiovascular care.

Pristine biochar typically exhibits limited capacity for heavy metal adsorption due to its inadequate pore development and insufficient surface functionality. This study introduces an innovative chemical strategy to enhance the surface of sawdust biochar with sulfur-based functional groups (C=S, C-S, S-S, S, S-H, -SO, -SO) to significantly improve cadmium (Cd) adsorption. Sulfur-doping using HSO, NaS, and NaSO markedly increased the sulfur content from 0.

Herein, a novel nanocomposite (carbonized chitosan-zinc oxide-magnetite, CCZF) was developed to effectively remove toxic elements in water remediation. Combining the high adsorption capacities of chitosan with the magnetic properties of magnetite and the chemical stability of zinc oxide, the combination of these unique properties makes it an efficient and versatile material that offers a sustainable solution for water purification. The (CCZF) nanocomposite was synthesized through the coprecipitation method and characterized using various techniques, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET) analysis, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and zeta potential analysis.

Actinomycosis is a rare bacterial infection characterized by nonspecific clinical and radiological manifestations. It often presents in cervicofacial, abdominopelvic, and thoracopulmonary forms, with cervicofacial being the most common. The extensive differential diagnosis and vague clinical and radiological features contribute to diagnostic challenges.

Cardiovascular disease (CVD) is a major global health challenge, and its co-occurrence with diabetes mellitus (DM) contributes significantly to morbidity and mortality. Yemen, a nation facing unique healthcare complexities, necessitates an in-depth investigation into the prevalence of cardiovascular risk (CVR) factors among its population with DM. This systematic review and meta-analysis aimed to determine the prevalence of CVR factors among individuals with diabetes in Yemen, to understand and highlight the knowledge gap, and to influence targeted interventions and policies.

Background And Objectives: Statins are used for metabolic dysfunction-associated steatotic liver disease (MASLD) (NAFLD) treatment, but their role in this context is unclear. Genetic variants of patatin-like phospholipase domain containing 3 (PNPLA3) are associated with MASLD susceptibility and statin treatment efficacy. Access to liver biopsies before established MASLD is limited, and statins and PNPLA3 in early liver steatosis are thus difficult to study.

Circadian rhythms, which regulate essential physiological and behavioral processes, are crucial for maintaining overall health and well-being. However, disruptions to these rhythms, particularly due to trans-meridian travel and shift work, can lead to significant health issues, including jet lag, metabolic imbalances, and neuropsychiatric disorders. In this systematic review, conducted in line with Preferred Reporting Items for Systematic Reviews and Metanalysis (PRISMA) 2020 guidelines, we explore the effectiveness of various interventions aimed at realigning circadian rhythms disrupted by such factors.

Acute cholecystitis (AC) is a prevalent surgical emergency, particularly among elderly individuals who present with high perioperative risks. While early cholecystectomy (CCY) is the standard treatment, percutaneous cholecystostomy (PC) is proposed as an alternative for high-risk patients. This systematic review aims to evaluate the comparative safety and efficacy of CCY versus PC in managing AC among elderly and high-risk surgical patients.

Cancer cells metastatic to the leptomeninges encounter a metabolically-challenging extreme microenvironment. To understand adaptations to this space, we subjected leptomeningeal-metastatic (LeptoM) mouse breast and lung cancers isolated from either the leptomeninges or orthotopic primary sites to ATAC-and RNA-sequencing. When inhabiting the leptomeninges, the LeptoM cells demonstrated transcription downstream of retinoid-X-receptors (RXRs).
