Retinoic acid receptor-related orphan receptor alpha (RORalpha) is a member of the nuclear receptor superfamily. The mouse mutant staggerer (sg/sg) carries a deletion within the RORalpha gene. RORalpha plays a major role in cellular differentiation during development and growth. In the present study, we found a lower mean arterial blood pressure in sg/sg than in +/+ mice (80.1+/-1.2 and 87.0+/-...

BACKGROUND The cholinergic neurotransmission within the human mesenteric lymphatic vessels has been poorly studied. Therefore, our aim is to analyse the cholinergic nerve fibres of lymphatic vessels using the traditional enzymatic techniques of staining, plus the biochemical modifications of acetylcholinesterase (AChE) activity. MATERIALS AND METHODS Specimens obtained from human mesenteric l...

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...

The celiac trunk and the mesenteric arteries may present variations with different clinical significance. A celiacomesenteric trunk was discovered in a patient with mesenteric ischemia and a history of aortic bypass without inferior mesenteric artery reimplantation. Despite thrombectomies and digestive resections, the patient died. Anatomic variations like celiacomesenteric trunk must be known ...

The kidneys receive arterial supply from the paired renal arteries. During routine dissection we observed in an adult male cadaver the following variation. Bilateral variation is seen in 5%-10% of individuals. The right kidney was receiving 3 renal arteries. Two were arising from the abdominal aorta just below the origin of superior mesenteric artery and the 3(rd) artery was arising from aorta,...

A long-term, heavy methamphetamine user with life-threatening rectal hemorrhage was treated with transcatheter occlusion of the bleeding arteries. The bleeding blood vessels were vulnerable submucosal arteries, part of the collateral supply to the distal colon. Visceral arteriography demonstrates severe arterial stenotic lesions of the celiac axis, superior mesenteric artery and the inferior me...

essential thrombocythemia is a chronic myeloproliferative disorder characterized by a sustained proliferation of megakaryocytes, which leads to increased numbers of circulating platelets. hemorrhagic and/or thrombotic episodes are frequent, and thrombosis of both veins and arteries may develop. vessels in unusual sites may be involved, e.g., the hepatic veins, mesenteric veins, and the digital ...

Surgeon-modified retrograde branched extension limb assembling technique and bridged endografts were successfully used to exclude an asymptomatic pararenal abdominal aortic aneurysm and to reconstruct the superior mesenteric artery and bilateral renal arteries in a case with high-grade celiac artery stenosis, nondilated aorta above the superior mesenteric artery, and large lumen below the renal...

The gastrointestinal system is mainly supplied by celiac trunk (CelT), superior mesenteric artery (SMA), and inferior mesenteric artery [1]. The celiac trunk is a large arterial vessel of the upper abdomen which arises below the aortic hiatus at the level of T12th the vertebral body. It is divided into three main branches: common hepatic, splenic and left gastric arteries [2]. The SMA arises fr...

Ca is a crucial factor in the regulation of smooth muscle contraction. Store-operated Ca entry (SOCE) is one pathway that mediates Ca influx and smooth muscle contraction. Vessel contraction function usually alters with aging to cause severe vascular-related diseases. However, the underlying mechanism is still not fully understood. Here, we assessed intracellular Ca and vessel tension and found...
