Factors affecting the direct red cell effect on thrombosis: Hematocrit dilution and injury patterns.
J Trauma Acute Care Surg
December 2024
From the Department of Surgery, University of Cincinnati, Cincinnati, Ohio.
Background: Red blood cell (RBC) aggregation can be initiated by calcium and tissue factor, which may independently contribute to microvascular and macrovascular thrombosis after injury and transfusion. Previous studies have demonstrated that increased blood storage duration may contribute to thrombotic events. The aims of this study were to first determine the effect of blood product components, age, and hematocrit (HCT) on the aggregability of RBCs, followed by measurement of RBC aggregability in two specific injury models including traumatic brain injury (TBI) and hemorrhagic shock.

Spiking neural networks (SNNs) have attracted significant interest in the development of brain-inspired computing systems due to their energy efficiency and similarities to biological information processing. In contrast to continuous-valued artificial neural networks, which produce results in a single step, SNNs require multiple steps during inference to achieve a desired accuracy level, resulting in a burden in real-time response and energy efficiency. Inspired by the tradeoff between speed and accuracy in human and animal decision-making processes, which exhibit correlations among reaction times, task complexity, and decision confidence, an inquiry emerges regarding how an SNN model can benefit by implementing these attributes.

We study an exactly solvable random walk model with long-range memory on arbitrary networks. The walker performs unbiased random steps to nearest-neighbor nodes and intermittently resets to previously visited nodes in a preferential way such that the most visited nodes have proportionally a higher probability to be chosen for revisit. The occupation probability can be expressed as a sum over the eigenmodes of the standard random walk matrix of the network, where the amplitudes slowly decay as power-laws at large times, instead of exponentially.

Increasing evidence suggests that dysbiosis of gut microbiota exacerbates chronic kidney disease (CKD) progression. Curcumin (CUR) has been reported to alleviate renal fibrosis in animal models of CKD. However, the relationship between CUR and gut microbiome in CKD remains unclear.
