BACKGROUND AND PURPOSE Increasing evidence suggests that the omega-3 polyunsaturated acids (n-3 PUFA), docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are beneficial to cardiovascular health, promoting relaxation of vascular smooth muscle cells and vasodilation. Numerous studies have attempted to study these responses, but to date there has not been a systematic characterisation of ...

abstract bowel obstruction is a known complication after bariatric surgery especially roux-en-y gastric bypass. the known etiologies include internal hernia, jejunojejunostomy stricture, ileus, intussusceptions, superior mesenteric artery syndrome, incarcerated port site hernia, and adhesions. blood clot is a rare cause of small intestinal obstruction after laparoscopic roux-en-y gastric bypass...

THAT INCLUDED LONG-STANDING MUSCULAR DYSTROPHY presented with moderate-to-severe epigastric and mid-back pain. Family history was noncontributory. The patient worked as a full-time computer instructor. He was a social drinker and denied a history of cigarette smoking or illicit drug use. At initial presentation, vital signs were normal except for a blood pressure of 148/105 mm Hg. Physical exam...

The coeliac trunk and superior mesenteric artery are the anterior visceral branches of the abdominal aorta. The anatomical variations of these arteries are due to development of the anterior splanchnic arteries. A case of coeliacomesenteric trunk was reported in this study which was observed in a 72-year-old male cadaver during the routine dissection. This trunk with a diameter of 13.98 mm is o...

BACKGROUND Superior mesenteric artery aneurysm (SMAA) is an uncommon vascular disorder. Complications such as rupture have been reported. Once complication has been encountered both surgical and endovascular treatment techniques can be considered. CASE REPORT We present a case of 68-year old male patient with SMAA rupture treated by endovascular modality. CONCLUSIONS Endovascular therapy is...

Blood flow velocity and pulsatility index were measured with Doppler ultrasound in the superior mesenteric artery, coeliac axis, and anterior cerebral artery in 18 very low birth weight, small for gestational age infants, and compared with findings from 18 weight matched, and 18 gestation matched, appropriate for gestational age controls. Mean velocity in the superior mesenteric artery was lowe...

OBJECTIVES Cardiopulmonary bypass has been shown to cause hypoperfusion of certain vascular beds leading to multiple system organ failure. It has been reported that the gut may be an important trigger. The underlying mechanism is not fully known, but vascular changes, particularly those due to cooling, could play a role. METHODS We examined the effect of cooling (28 degrees C) and subsequent ...

When pulmonary hypertension occurs in the face of hypoxia there is remodeling of all three layers of the pulmonary vessels, but in particular, there is an increase in number of adventitial fibroblasts. Hypoxia causes vasoconstriction in the pulmonary circulation and vasodilation in the systemic circulation. We hypothesized that there are fundamental differences in oxygen sensing and cell signal...
