The formation of leaf vein patterns has fascinated biologists for centuries. Transport of the plant signal auxin has long been implicated in vein patterning, but molecular details have remained unclear. Varied evidence suggests a central role for the plasma-membrane (PM)-localized PIN-FORMED1 (PIN1) intercellular auxin transporter of Arabidopsis thaliana in auxin-transport-dependent vein patter...

Introduction The venous drainage of head and neck is divided into superficial and deep jugular systems. The deep jugular system consists of internal jugular vein and the superficial system consists of external and anterior jugular vein. External jugular vein is formed by the union of the posterior division of retromandibular vein and the posterior auricular vein below the ear in the substance o...

Adrenal vein development in utero occurs concurrently with the development of the inferior vena cava, the renal veins, and the gonadal veins. The embryologic formation of these veins involves communication of various venous systems. Although the left adrenal-renal vein complex is most commonly described as a shared emptying of the left adrenal vein and the left inferior phrenic vein into the le...

conclusions in our study, portal venous thrombosis was detected in the patient who died during the acute period only. a study including large numbers of budd-chiari-syndrome patients with behcet’s disease and portal venous thrombosis would be helpful to determine the prognostic significance of portal venous thrombosis in budd-chiari-syndrome patients with behcet’s disease. in addition, patients...

background: venous thromboembolism, which comprises deep vein thrombosis and pulmonary embolism and is a significant cause of morbidity and mortality among patients with cancer. the aim of the present study was to report a rare presentation of arterial thrombosis after venous thrombosis in a patient with gastric cancer. report of the case: a 45 year-old female patient with locally advanced gast...

purpose: to evaluate total plasma homocysteine level during the acute phase of central retinal vein occlusion (crvo) compared with a matched healthy group in iranian population, and determine whether hyperhomocysteinemia is also a risk factor for crvo. methods: a study group contains 54 patients presenting with crvo in recent one month, acute phase of the decease, was compared for fasting total...

the ramifications of the portal vein in the liver of horses were studied by using corrosion casting and gross dissection. the portal vein in the horse supplies the hepatic lobes by six major branches. the right lobe is supplied by three main branches, namely the dorsal diaphragmatic, the right caudodorsal and the right intermediate branches. the left branch supplies the left lateral and medial ...

a quasi experimental study was conducted in the labour rooms of one of the hospital's of the university of   medical science of iran, to compare the effect ofcord blood drainage and oxytocin injection into the umblicat   vein in the duration of the third stage of labour.   a total of 180 women in the course of normal pregnancies with no complications and normal vaginal   dd ivery were sele...
