In the present study, myogenic properties of femoral arteries from control hindlimbs and those distal to external iliac artery partial ligation of spontaneously hypertensive rats (SHRs) and normotensive Wistar-Kyoto (WKY) rats were assessed. Arterial pressure was reduced distal to the ligature in both strains. Media thickness/lumen diameter (M/L) ratios of control (unligatured) SHRs were greate...

introduction: arterial stiffness is an important predictor of cardiovascular risk. several indices have been  introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. since the  substitution  of  the  blood  pressure  changes  in  the  central  arteries  such  as  carotid  with  the  blood  pressure  changes in the brachial results in error in the blood...

materials and methods a number of 100 patients with imr, normal karyotypes and negative fragile-x and metabolic tests were screened for subtelomeric abnormalities using mlpa technique. results nine of 100 patients showed subtelomeric abnormalities with at least one of the two mlpa kits. deletion in a single region was found in 3 patients, and in two different subtelomeric regions in 1 patient. ...

heart failure is a clinical syndrome characterized by the inability of the heart to provide nutrient supply to tissues. in 75% of cases, the underlying pathology causing heart failure in patients with cardiac death is coronary heart disease. a rabbit model of heart failure with coronary ligation was produced to mimic coronary heart disease in humans. after producing the model, two arteries and ...

BACKGROUND Intestinal ligation is the cornerstone for damage control in abdominal emergency, yet it may lead to bowel ischemia. Although intestinal ligation avoids further peritoneal cavity pollution, it may lead to an increased pressure within the bowel segments and rapid bacterial translocation. In this study, we showed that severed intestine could be readily reconnected by using silicon tube...

OBJECTIVE To define whether increases in gastric intramural tissue CO2 and H+ increase during experimentally induced peritonitis with circulatory shock as they do under conditions of hemorrhagic shock and cardiac arrest. DESIGN AND SETTING Peritonitis was induced in Sprague-Dawley rats by cecal ligation and fecal spillage. MEASUREMENTS AND RESULTS Over an interval of 260 +/- 20 min in 5 ani...

INTRODUCTION The degree of hypertrophy of the future liver remnant (FLR) induced by associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in patients with HCC and chronic liver disease is often limited as compared with patients with a healthy liver. PRESENTATION OF CASE We reported a 53-year-old male who had a huge HCC (14.8×12×9.4cm) arising from a background of...

background: when we perform surgery in utero, lungs have an appropriate time to decrease magnitude of hypoplasia, with surgery in uterus. methods: six time-dated single-fetus ewes were selected to induce diaphragmatic hernia. fetal lambs were divided proportionally into 2 groups, namely group 1, diaphragmatic hernia and tracheal ligation (tl group), and group 2, diaphragmatic hernia only (nl gr...

Type II endoleaks occur commonly following endovascular aneurysm repair (EVAR). Although they remain enigmatic, multiples studies have evaluated preoperative risk factors and strategies for prevention of type II endoleaks. Prophylactic treatment of type II endoleaks can include embolization of accessory arteries, as well as complete aneurysmal sac occlusion. Regular post-operative surveillance ...

BACKGROUND Vaginal radical trachectomy (RT) ligates and cuts several arteries supplying the uterus. Changes of blood supply to the uterus in two patients who experienced pregnancy and delivery were studied by using 3-D CT scanning. Effects of changes of blood supply to the uterus on the pregnancy courses were also examined. METHODS Vascular distribution in the uterus was studied in two patien...
