the major objective of the present study was to characterize the effects of oxidants generated b xanthine (x) plus xanthine oxidase (xo) on isolated rat ileum motility. the effects of three concentrations of x/xo on the basal tone of the rat ileum preparation were studied for 20 minutes. developed tensions were measured in mg/mg tissues and then expressed as percentage of baseline tension. also...

Patellofemoral (PF) osteoarthritis (OA) is a somewhat predominant illness, affecting up to 24% of women and 11% ofmen over the age of 55 years who suffer from symptomatic knee OA. The purposes of this narrative overview are tosummarize the present situation of patellofemoral arthroplasty (PFA) in the treatment of solitary PF-OA, and to givean account of the clinical results of...

major pancreatic injury following blunt abdominal trauma by itself is a relatively rare occurrence, and in vast majority of cases (95%) it is associated with injury to adjacent major vessels and organs; thus making isolated major pancreatic injury even rarer. while most pancreatic injuries are managed by simple measures like debridement and drainage, complex proximal injury poses surgical chall...

it has been pointed out the static lateral response procedure for a base-isolated structure proposed in international building code (ibc) somewhat overestimates the seismic story force. that is why in the current paper, vertical distribution of base shear over the height of isolated structures considering higher mode effects under near field earthquakes is investigated. nonlinear behavior of is...

cigarette smoking is one of the main risk factors for premature human death associated to a variety of respiratory and vascular diseases, and cancer due to containing hundreds of toxicants. rat mitochondria were obtained by differential ultracentrifugation and incubated with different concentrations (1, 10 and 100%) of standardized cigarette smoke extract (cse). our results showed that cigarett...

ATP-sensitive potassium (KATP) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. There has been considerable interest in exploring KATP channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. The purpose of this study was to synthesize 3,3,6,6-tet...
