Maintaining a healthy pool of circulating red blood cells (RBCs) is essential for adequate perfusion, as even minor changes in the population can impair oxygen delivery, resulting in serious health complications including tissue ischemia and organ dysfunction. This responsibility largely falls to specialized macrophages in the spleen, known as red pulp macrophages, which efficiently take up and recycle damaged RBCs. However, questions remain regarding how these macrophages are acutely activated to accommodate increased demand.

Transition metal dichalcogenides (TMDs) have been extensively studied as efficient photocatalysts for water splitting. However, the utilization efficiency of photogenerated carriers remains a major limitation for their practical applications. An effective approach to address this issue is the construction of Z-scheme heterostructures.

Oxidative stress has attracted attention as an indicator of exercise load. Minimizing the impact on the body is essential during underwater treadmill exercise. Here, we conducted an exploratory study of the effects of dermal suction, which has been reported to improve blood flow in healthy dogs, prior to underwater treadmill exercise.

BackgroundDuring cardiopulmonary bypass (CPB), goal-directed perfusion (GDP) seeks to match oxygen delivery to metabolic demand, but the dynamics of oxygen extraction and intraoperative oxygen demand remain poorly understood, especially in paediatric populations. Existing models rely on limited data and assume, for example, a linear relationship between log oxygen demand and temperature.MethodsWe developed GARIX (Global AutoRegressive Integrated model with eXogenous variables and an equilibrium force) to predict minute-by-minute changes in oxygen extraction ratio (OER) using high-resolution intraoperative data.

Heavy metal (HM) co-contamination is prevalent in the aquatic ecosystems and often induces complex combined effects such as synergism or antagonism, bioconcentration and biomagnification on the food-chain organisms, which is threatening the survival of living creatures and even to human health. However, the combined effects of HMs under combined exposure on the aquatic food chains still remain poorly understood. Therefore, toxic responses, bioconcentration and biomagnification of four typical HMs, lead (Pb), cadmium (Cd), nickel (Ni) and zinc (Zn), were systematically investigated under different combined exposure conditions.
