Pulsatile flow perfusion (PFP) requires smaller volume of additional infusion. Extravascular hyperhydration is more marked after nonpulsatile flow perfusion (NPFP). In NPFP there is an increase in free water clearance, lower urinary osmolality and diuresis rate. PFP prevents urinary hypoosmolality and retains baseline values of free water clearance. No significant differences in Na+ urinary excretion have been revealed. Bilirubinemia level following NPFP was significantly higher than the baseline level, while following PFP the level of total and bound bilirubin remained unchanged. No differences in the total hepatic flow have been observed during pulsatile and nonpulsatile flow perfusion.

Ischemia-reperfusion (I/R) injury is a process in which impaired perfusion is restored by restoring blood flow and tissue recirculation. Nanomedicine uses cutting-edge technologies that emerge from interdisciplinary influences. In the literature, there are very few in vivo and in vitro studies on how cerium oxide (CeO) affects systemic anti-inflammatory response and inflammation.

Three-dimensional (3D) tissue culture models provide in vivo-like conditions for studying cell physiology. This study aimed to examine the efficiency of pyramidal microwell geometries in microfluidic devices on spheroid formation, cell growth, viability, and differentiation in mouse embryonic stem cells (mESCs). The static culture using the hanging drop (HD) method served as a control.

Despite significant advancements in achieving high recanalization rates (80%-90%) for large vessel occlusions through mechanical thrombectomy, the issue of "futile recanalization" remains a major clinical challenge. Futile recanalization occurs when over half of patients fail to experience expected symptom improvement after vessel recanalization, often resulting in severe functional impairment or death. Traditionally, this phenomenon has been attributed to inadequate blood flow and reperfusion injury.

Increased tortuosity of highrisk vessels within the CW has been implicated as a marker in the progression of cerebrovascular diseases especially in structures like the internal carotid artery (ICA). This is partly due to age-related plaque deposition or arterial stiffening.
