We compared the protective effects of ischemic preconditioning (IPC) and the Na(+)/H(+) exchanger-1 (NHE-1) inhibitor cariporide in isolated rat hearts subjected to global ischemia (45 or 90 min) and 30-min reperfusion and determined the protective effects of cariporide under IPC blockade with the mitochondrial ATP-sensitive K(+) channel blocker 5-hydroxydecanoate (5-HD). With 45-min ischemia, ...
Reactive oxygen species (ROS) are believed to be involved in triggering cardiac ischemic preconditioning (IPC). Decreased formation of ROS on reperfusion after prolonged ischemia may in part underlie protection by IPC. In heart models, these contentions have been based either on the effect of ROS scavengers to abrogate IPC-induced preservation or on a measurement of oxidation products on reperf...
Interpersonal postural coordination (IPC) produced by interpersonal light touch (ILT), whereby time-series variations in the postural sway between two people unintentionally resemble each other, may be a possible social interaction. From a sociopsychological standpoint, close mutual behavioral coordination is recognized as "social glue," which represents the closeness of relationships and contr...
This study investigated the effects of ischemic preconditioning (IPC) on the ratings of perceived exertion (RPE), surface electromyography, and pulmonary oxygen uptake (V̇o2) onset kinetics during cycling until exhaustion at the peak power output attained during an incremental test. A group of 12 recreationally trained cyclists volunteered for this study. After determination of peak power output...
OBJECTIVES Recruitment of the survival kinase cascades, PI3K-Akt and Raf-MEK1/2-Erk1/2, at the time of reperfusion, following a lethal ischemic insult, may mediate the protection associated with ischemic preconditioning (IPC). The exact interplay between these two kinase cascades in mediating this effect is not clear. We examine the 'cross-talk' between these kinase cascades in their contributi...
Ischemic preconditioning (IPC), a strategy used to attenuate ischemia-reperfusion injury, consists of brief ischemic periods, each followed by reperfusion, prior to a sustained ischemic insult. The purpose of the present study was to evaluate the local and systemic anti-inflammatory effects of hind limb IPC in male Wistar rat (200-250 g) models of acute inflammation. IPC was induced with right ...
OBJECTIVE To explore the effect of bone marrow mesenchymal stem cells (MSCs) on endotoxin-induced acute lung injury in mice and verify the role of exosome. METHODS Exosome was isolated from the culture supernatant of MSC. For ischemic preconditioning, MSCs were subjected to anoxia for 0 min (MSCs group), 30 min (MSCs(IPC-30) group), 60 min (MSCs(IPC-60) group) and 90 min (MSCs(IPC 90) group),...
مقدمه: ایسکمیک پره کاندیشنینگ (ischemic preconditioning) پدیده ای است که در طی آن دوره های کوتاه مدت ایسکمی موجب حفاظت قلب در مقابل آسیب های ناشی از ایسکمی طولانی می گردد. پیشنهاد گردیده که ماده نیتریک اکساید (no) یک ماده موثر در پدیده فوق می باشد. هدف از این مطالعه بررسی اثرات no برروی عملکرد قلبی در طی ایسکمی و پرفیوژن مجدد در قلب ایزوله موش صحرایی می باشد. روش کار: در این مطالعه تجربی از 28 ...
Cardioprotection by ischemic preconditioning (IPC) is impaired during hyperglycemia, but the mechanisms underlying this phenomenon are poorly understood. This study investigated the role of hyperglycemia to adversely modulate tetrahydrobiopterin (BH(4)) and heat shock protein 90 (Hsp90) during cardioprotection by IPC. Rabbits or mice underwent 30 min of coronary occlusion followed by reperfusio...
BACKGROUND Disruption of the lymphatic circulation through breast carcinoma-associated axillary lymph node dissection, with or without radiation therapy, reportedly is the most common cause of lymphedema in developed countries. There is no cure for breast carcinoma-associated lymphedema. Although intermittent pneumatic compression (IPC) has been acknowledged as a potential component of the mult...
