Aim of the study was to assess current state implementating key aspects infection prevention and control (IPC) in Armenian hospitals, defined by main WHO components, using survey tool IPCAF (Infection Prevention Control Assessment Framework). Materials methods. 113 hospitals were involved study. All participants filled out questionnaire, consisting 8 sections (each rated up 100 points) devoted ...

AIM Intermittent pneumatic compression (IPC) increases systemic fibrinolytic activity but may also injure endothelial cells and thereby induce coagulation. The safety and utility of IPC in patients with peripheral arterial disease (PAD) therefore remains uncertain. The aim of this study was to determine whether IPC is associated with coagulation activation and endothelial cell damage, platelet ...

Previous work from our laboratory has shown that the sarcolemmal K(ATP) channel (sK(ATP)) is required as a trigger for delayed cardioprotection upon exogenous opioid administration. We also established that the mitochondrial K(ATP) (mK(ATP)) channel is not required for triggering delayed delta-opioid-induced infarct size reduction. Because mechanistic differences have been found among delta-opi...

BACKGROUND/AIMS Degradation of adenine nucleotides to adenosine has been suggested to play a critical role in ischemic preconditioning (IPC). Thus, we questioned in patients undergoing partial hepatectomy whether (i) IPC will increase plasma purine catabolites and whether (ii) formation of purines in response to vascular clamping (Pringle maneuver) can be attenuated by prior IPC. METHODS 75 p...

Earlier studies on the effects of the herbicide isopropyl iV-phenylcarbamate (IPC) on mitosis revealed blocked metaphases, multinucleate cells, giant nuclei and an increase in number of partly contracted chromosomes. It was assumed that IPC, like colchicine, was causing these effects by disruption of the spindle apparatus by destroying the spindle microtubules. The animal hormone melatonin caus...

The majority of research in the field of automated planning focuses on the synthesis of plans for problems that are solvable. We propose an IPC track to focus on the important and understudied area of unplannibility: proving that a planning problem is unsolvable. We will focus on classical planning problems, as methods for determining whether or not unplannability can have wider applications fo...

Birds have rapidly responding respiratory chemoreceptors [intrapulmonary chemoreceptors (IPC)] that provide vagal sensory feedback about breathing pattern. IPC are exquisitely sensitive to CO(2) but are unaffected by hypoxia. IPC continue to respond to CO(2) during hypoxic and even anoxic conditions, suggesting that they may generate ATP needed for signal transduction anaerobically. To assess I...

PURPOSE Ischemic preconditioning (IPC) protects the rat retina against the injury that ordinarily follows prolonged ischemia. It has been shown that release of adenosine, de novo protein synthesis, and mediators, such as protein kinase C and K(ATP) channels, is required for IPC protection. However, the molecular mechanisms of neuroprotection by IPC are unknown. Retinal cells die after ischemia ...

The impact of ischemic preconditioning (IPC) on contraction, Ca(2+) homeostasis, and cell survival was compared in isolated ventricular myocytes from young adult ( approximately 3 mo) and aged ( approximately 24 mo) male Fischer-344 rats. Myocytes were field stimulated at 4 Hz (37 degrees C). Contraction (edge detector) and intracellular Ca(2+) (fura-2) were measured simultaneously. Viability w...

RATIONALE Redox modifications play an important role in many cellular processes, including cell death. Ischemic preconditioning (IPC) has been shown to involve redox signaling. Protein S-nitrosylation (SNO) is increased following myocardial IPC, and SNO is thought to provide cardioprotection, in part, by reducing cysteine oxidation during ischemia/reperfusion (IR) injury. OBJECTIVE To test th...
