Numerous biological processes are regulated by the intercellular communications arising from extracellular vesicles (EVs) released from cells. However, the mechanisms that regulate the quantity of EV discharged have yet to be understood. While it is known that ATP9A, a P4-ATPase, is involved in endosomal recycling, it is not clear whether it also contributes to the release of EVs and the makeup of exosomal lipids. This study is aimed at exploring the role of human ATP9A in the process of EV release and, further, to analyze the profiles of EV lipids regulated by ATP9A. Our results demonstrate that ATP9A is located in both the intracellular compartments and the plasma membrane. The percentage of ceramides and sphingosine was found to be significantly greater in the control cells than in the ATP9A overexpression and ATP9A knockout groups. However, EV release was greater in ATP9A knockout cells, indicating that ATP9A inhibits the release of EVs. This study revealed the effects of ATP9A on the release of EVs and the lipid composition of exosomes.Ischemic stroke is the major type of cerebrovascular disease usually resulting in death or disability among the aging population globally. Oxidative stress has been closely linked with ischemic stroke. Disequilibrium between excessive production of reactive oxygen species (ROS) and inherent antioxidant capacity leads to subsequent oxidative damage in the pathological progression of ischemic brain injury. Acupuncture has been applied widely in treating cerebrovascular diseases from time immemorial in China. This review mainly lays stress on the evidence to illuminate the possible mechanisms of acupuncture therapy in treating ischemic stroke through regulating oxidative stress. We found that by regulating a battery of molecular signaling pathways involved in redox modulation, acupuncture not only activates the inherent antioxidant enzyme system but also inhibits the excessive generation of ROS. find more Acupuncture therapy possesses the potential in alleviating oxidative stress caused by cerebral ischemia, which may be linked with the neuroprotective effect of acupuncture.

Emerging evidence has shown that pinocembrin protects the myocardium from ischemic injury in animals. However, it is unknown whether it has cardioprotection when given at the onset of reperfusion. Also, mechanisms mediating the cardioprotective actions of pinocembrin were largely unknown. Thus, this study is aimed at investigating the effects of pinocembrin postconditioning on ischemia-reperfusion (I/R) injury and the underlying mechanisms.

The

mouse model of myocardial I/R injury,

isolated rat heart with global I/R, and

hypoxia/reoxygenation (H/R) injury model for primary cardiomyocytes were used.

We found that pinocembrin postconditioning significantly reduced the infarct size and improved cardiac contractile function after acute myocardial I/R. Mechanically, in primary cardiomyocytes, we found that pinocembrin may confer protection in part via direct stimulation of cardiac glycolysis via promoting the expression of the glycolytic enzyme, PFKFB3. Besides, PFKFB3 inhibition abolished pinocembrin-induced glycolysis and protection in cardiomyocytes. More importantly, PFKFB3 knockdown via cardiotropic adeno-associated virus (AAV) abrogated cardioprotective effects of pinocembrin. Moreover, we demonstrated that HIF1

is a key transcription factor driving pinocembrin-induced PFKFB3 expression in cardiomyocytes.

In conclusion, these results established that the acute cardioprotective benefits of pinocembrin are mediated in part via enhancing PFKFB3-mediated glycolysis via HIF1

, which may provide a new therapeutic target to impede the progression of myocardial I/R injury.

In conclusion, these results established that the acute cardioprotective benefits of pinocembrin are mediated in part via enhancing PFKFB3-mediated glycolysis via HIF1α, which may provide a new therapeutic target to impede the progression of myocardial I/R injury.BACKGROUND The Triplex method is a three-step treatment approach to reducing the appearance of small and medium-sized varicose veins and phlebological imperfections of the lower limbs. OBJECTIVE This study evaluated the effectiveness, duration of results, adverse events, patient satisfaction, and improvements in quality of life in patients with small and medium-sized varicose veins who were treated with the Triplex method. METHODS We conducted a six-year follow-up study of 4,000 patients from the years 2012 to 2018. Patients with chronic venous insufficiency of the lower limbs were included. Patients with active or previous phlebitis or phlebostatic ulcers were excluded. An average of three sessions was performed on each patient in the Triplex group. Follow-up assessments were performed 1, 3, 6, and 12 months after the completion of the treatment, and they included a morphofunctional study, histological examination, and photographic documentation. The first step of the treatment approach utilized an injectablf the varices; 2) reduced utilization of the foam solution at the reflux point due to the narrowing of the gauge; and 3) no relevant hemodynamic effects emerged in patients with recanalization. In patients who underwent Steps 1 and 2 of the treatment approach, reflux was not hemodynamically significant. No significant differences were observed in the lauromacrogol group of patients compared to the sodium tetradecyl sulfate group. CONCLUSION Compared to patients in whom only scleromousse was performed at the reflux site, the narrowing of the varicose wall that is achieved using the Triplex method is associated with longer lasting results in the treatment of small and medium-sized varicose veins, with physiological recovery of superficial venous circulation.BACKGROUND Dry, flaky skin remains one of the most common and vexing of human disorders. The anterior shin is a challenging area to treat in women with scaly skin. OBJECTIVE We sought to investigate whether a lactic acid/ceramide lotion improves the texture and appearance of dry skin through moisturization and desquamation. METHODS This was a randomized, single-center, controlled, evaluator-blinded, within-subject comparison of a lactic acid/ceramide lotion versus no treatment. The lotion was applied twice daily for 14 days, with evaluations performed on Days 1, 2, and 14. A total of 56 healthy female subjects, older than 50 years of age, with Fitzpatrick Skin Types I through VI and dry, rough skin on the anterior shins (defined as Grades 3-4 by investigator evaluation) were included in the study. Assessments of change in skin appearance following desquamation and moisturization by D-SQUAME® analysis and an investigator assessment on the Dry Skin Scale were performed on Days 1, 2, and 14. Additionally, subjects completed a self-assessment questionnaire on Day 1 and Day 14.
