Arsenic (As) contamination in rice poses a significant threat to human health due to its toxicity and widespread consumption. Identifying and manipulating key genes governing As accumulation in rice is crucial for reducing this threat. The large NIP gene family of aquaporins in rice presents a promising target due to functional redundancy, potentially allowing for gene manipulation without compromising plant growth.

This work consists of the study of the time-fractional human liver model with the Caputo-Fabrizio fractional derivative. The existence and uniqueness of the proposed model are shown using fixed point theory. Also, the stability of the considered model is shown using the Ulam Hyres theorem and the Lyapunov function.

Developed as a 1-stage procedure, HCR has not been widely adopted by the cardiovascular community. The recommended minimally invasive approach through a small left thoracotomy incision is technically demanding, and same-day percutaneous revascularization requires a hybrid operating room that is not available in most hospitals.

In contrast to native coronary artery, percutaneous revascularization does not impede the progression of saphenous vein atherosclerosis and saphenous vein graft failure commonly ensues. The protracted patency of arterial grafts is likely to account for most of the long-term superiority of coronary artery bypass surgery over percutaneous revascularization in patients with complex coronary artery disease.

Pre-CS refers to the period of rapid hemodynamic deterioration that precedes overt CS with hypotension, inflammatory response, and end-organ failure. Mortality remains extremely high in CS and has not improved over the past decades.

We appraise the strength of the association between epicardial adipose tissue and development/progression of cardiovascular diseases like coronary artery disease, atrial fibrillation, and heart failure with preserved ejection fraction.
Recent Findings: Cross-sectional clinical and translational correlative studies have established an association between epicardial adipose tissue and progression of coronary artery disease.
Purpose Of Review: Whether the present obesity epidemic will increase the prevalence of pulmonary hypertension over the next decades is unclear. We review the obesity-related mechanisms that may further the development and progression of pulmonary hypertension.
Recent Findings: Systemic and local inflammation, insulin resistance and oxidative stress contribute to the pathobiology of obesity and pulmonary arterial hypertension.

The present paper discusses the analysis of solution of groundwater flow in inclined porous media. The problem related to groundwater flow in inclined aquifers is usually common in geotechnical and hydrogeology engineering activities. The governing partial differential equation of one-dimensional groundwater recharge problem has been formed by Dupuit's assumption.
