Motivated by the recent successful synthesis of a new nanocarbon, namely, a warped, double-concave graphene "Pringle" (Nat. Chem., 2013, 5, 739), we investigate properties of warped boron-nitride (BN) and aluminum-nitride (AlN) analogues, i.e., the non-planar B40N40H30 and Al40N40H30 "Pringles" using density functional theory (DFT) calculations. Particular attention is placed on the effect of n...

BACKGROUND The liver is the most commonly injured organ in blunt abdominal trauma. Although major hepatic bleeding may be partially controlled with portal triade clamping (the Pringle's maneuver), continuous prolonged clamping results in liver ischemia. OBJECTIVES The purpose of this study was to determine the safe time of Pringle maneuver based on pathologic changes of liver in rabbit models...

conclusions continuous portal triade clamping (the pringle maneuver) during liver ischemia (30 and 45 minutes) in rabbits resulted in no ischemic change. increasing time of clamping to 30 minutes was safe in intermittent pringle maneuver. materials and methods in an experimental study, 20 new-zealand white rabbits were selected. in laparotomy, a blunt dissector was passed through the foramen of...

Acrylamide is one of the most important contaminants in the environment. Acrylamide was shown to be a neurotoxicant, reproductive toxicant, and carcinogen in animals. There is consensus among international food safety groups that acrylamide in the diet should be assessed. In the present study, we surveyed by Gas Chromatography-Mass Spectrometry (GC-MS) the levels of acrylamide in 23 foods marke...

background during the four steps of the valsalva maneuver (vm), opposite changes can be observed in some physiologic parameters. manifestations of the vm in the electrocardiogram (ecg) have been studied in detail, but there have been few reports comparing vm-related biochemical and hemodynamic changes with a focus on the strain phase of the vm. objectives we studied strain-related ecg changes d...

background :although  laparoscopic   cholecystectomy  is   associated  with  less   post-operative  pain compared  to   open  cholecystectomy,  diffuse  shoulder  and  abdominal  pain  is   one    of   the    main postoperative complications in  this technique. the  aim  of this study was  to  compare the  abdominal and shoulder pain after laparoscopic cholecystectomy by  applying intra-abdomin...
