femoral hernias account for 2% to 4% of groin hernias, are more common in women, and are more appropriate to present with strangulation and require emergency surgery. this condition may lead to symptoms of bowel obstruction or strangulation and possible bowel resection-anastomosis. to the best of our knowledge, there is few reports of strangulated femoral hernia. we herein present an 82-year-ol...

background: transport of the critically ill patient is potentially risky and the transport team should be careful in making decision and be prepared to deal with them in any condition. our physicians are not qualified in safe transport. we want to evaluate the effect of small group teaching method for promotion of physicians' skills in transport of critically ill patients. methods: in an interv...

abstract   background: recently, small dense low density lipoprotein (sdldl) has been highlighted as a new risk factor for the coronary artery disease (cad).small dense ldls are believed to be atherogenic since these particles are taken up more easily by arterial wall. they are readily oxidized and have reduced affinity for low density lipoprotein (ldl) receptor and increased affinity for arter...

in this study, several designed creb1-specific shrnas cloned into lentiviral transfer vectors were screened in293t by transient transfection assays. relative creb1 expression was determined by relative qrt-pcr. all of the designed shrnas gave some level of knockdown. one shrna was more effective for knocking down the specific gene among others. the predicted sirnas activities as determined by r...

this cross-sectional study was conducted to estimate seroprevalence and to identify flock-level factors associated with seropositivity to brucellosis in small ruminants in kerman province, southeastern iran. in october-november 2011, serum samples were randomly collected from 1767 sheep and 1233 goats, older than 18 months, from 300 flocks. the sera were initially screened for the presence of a...

this study was designed to investigate the demand for institutional credit among small scale farmers in imo state. a sample of 40 livestock and 50 food crop farmers were selected respectively using multistage random sampling technique. data were collected with a well structured questionnaire administered to a total of 90 randomly selected farmers. data collected were analyzed using descriptive ...

conclusions the application of 5-ht1a, 5-ht2, 5-ht3, 5-ht4, 5-ht6 and 5-ht7 receptor antagonists, applied at concentrations lower than 1.0 µm did not modify the efs-induced contraction and relaxation responses, whichsuggests the unlikely involvement of endogenous 5-ht in mediating responses to efs in the described test conditions. materials and methods segments taken from the rat duodenum, jeju...

tumor growth has a number of features in common with a physical process known as molecular beam epitaxy (mbe). so using the same equations for tumor growth is sensible. however, tumor substrate unlike mbe is not planar that makes necessary a geometrical treatment of the growth equations. a variety of mathematical models have been proposed to describe tumor growth. the justification for these mo...

background: the presence of small intestine in the radiation field during pelvic cancers treatment causes an interruption in radiotherapy. a non-invasive method was developed to exclude small intestine during conventional radiotherapy. materials and methods: the incidence of the radiation therapy interruption is highly dependent upon the area of the small intestine included in the portals and i...

abstract background: coherent scattering leads to diffraction effects and especially constructive interferences. theseinterferences carry some information about the molecular structure of the tissue. as breast cancer isthe most widespread cancer in women, this project evaluated the application of small anglex-ray scattering (saxs) for differentiation between normal and cancerous breast tissues....
