Aging is an important risk factor for stroke. We evaluated the effects of aging on cell susceptibility to oxygen and glucose deprivation (OGD) in slices of the hippocampus from Wistar rats aged 2, 11 and 24 months. Lactate dehydrogenase (LDH) released to the incubation media and free radical content were markedly increased in the 24-month group submitted to OGD. These results confirm that hippocampal tissue from old animals is more susceptible to ischemia-reoxygenation injury.

Background: High-flow nasal cannula (HFNC) therapy has developed as a valuable tool for respiratory support in pediatric critical care. It offers an intermediate level of support between traditional low-flow oxygen and non-invasive ventilation (NIV). Studies suggest its effectiveness in improving oxygen delivery, work of breathing, and secretion clearance.

Obstructive sleep apnea (OSA), a highly prevalent and serious disorder with significant complications, causes considerable daytime and nighttime symptoms as well as long-term consequences and is yet an underdiagnosed and inadequately treated condition. Patients with OSA undergo frequent awakenings during the sleep cycle and find it impossible to get restorative sleep. Individuals are extremely fatigued, sleepy, and irritable throughout the day.

Blood-contacting medical devices, especially extracorporeal membrane oxygenators (ECMOs), are highly susceptible to surface-induced coagulation because of their extensive surface area. This can compromise device functionality and lead to life-threatening complications. High doses of anticoagulants, combined with anti-thrombogenic surface coatings, are typically employed to mitigate this risk, but such treatment can lead to hemorrhagic complications.

In this environment, respires nitrate and increases transport and utilization of alternative carbon sources via the cAMP receptor protein (CRP), a transcription factor that is active during glucose scarcity. Here we show that nitrate respiration in aerated cultures is under control of CRP and, therefore, glucose availability.

In this study, the zirconium-based metal organic framework (Zr-MOF) was applied as the adsorbent for phosphorus (P) pollution in water. Then the phosphate-adsorbed metal organic frameworks (MOFs) were used as a recycled raw material and calcined to obtain P-doped MOFs-derived carbon material (ZrP@Zr-BTC). Next, the ZrP@Zr-BTC was used for peroxymonosulfate (PMS) activation for the ceftriaxone sodium degradation.
