BACKGROUND: Recent studies, mainly on animal models, have suggested that negatively charged glycosaminoglycans, macrophages, and lymph vessels in the skin interstitium may serve as extrarenal control of sodium balance and blood pressure. The aim of the study was to prove the hypothesis that skin interstitium has a role in the pathogenesis of hypertension in humans. METHODS AND RESULTS: We have examined skin biopsies in 91 patients from the department of surgery who had elective surgery with abdominal skin incision: 43 were hypertensive, 14 had resistant hypertension, and 34 with normal blood pressure as control group (median patients' age in these groups estimated accordingly 64 vs...

BACKGROUND: Peripheral arterial disease (PAD) is a complex and highly prevalent pathology. It has been estimated that ∼8.5 million people in the United States are affected by PAD, of which 12%-20% are older than age 60. The TransAtlantic Inter-Society Consensus (TASC) guidelines classified aortoiliac atherosclerotic disease based on morphology and level of lesions. TASC II guidelines recommend bilateral surgical bypass to the femoral arteries for TASC II C and D lesions. The aortobifemoral bypass (ABF) has been considered the gold standard in the treatment of aortoiliac occlusive disease (AIOD)...

Lutheran/basal cell adhesion molecule (Lu/BCAM) is a transmembrane adhesion molecule expressed by erythrocytes and endothelial cells that can interact with the extracellular matrix protein laminin-α5. In sickle cell disease, Lu/BCAM is thought to contribute to adhesion of sickle erythrocytes to the vascular wall, especially during vaso-occlusive crises. On healthy erythrocytes however, its function is unclear. Here we report that Lu/BCAM is activated during erythrocyte aging. We show that Lu/BCAM-mediated binding to laminin-α5 is restricted by interacting, in cis, with glycophorin-C-derived sialic acid residues...

Vascular endothelial growth factor (VEGF) and its receptor, VEGFR2, serve a critical role in angiogenesis and lymphangiogenesis, which are involved in the initiation and progression of malignancies. Specific single nucleotide polymorphisms of VEGF and VEGFR2 have been shown to modulate gene expression and influence malignancy aggressiveness. The aim of the present study was to determine whether the VEGFR2 rs2071559 (T/C) polymorphism is associated with the risk of developing nasopharyngeal carcinoma (NPC) and the aggressiveness of NPC in a southern Chinese population...

Vascular endothelial growth factor (VEGF) is a potent growth factor playing diverse roles in vasculogenesis and angiogenesis. In the brain, VEGF mediates angiogenesis, neural migration and neuroprotection. As a permeability factor, excessive VEGF disrupts intracellular barriers, increases leakage of the choroid plexus endothelia, evokes edema, and activates the inflammatory pathway. Recently, we discovered that a heparin binding epidermal growth factor like growth factor (HB-EGF)-a class of EGF receptor (EGFR) family ligands-contributes to the development of hydrocephalus with subarachnoid hemorrhage through activation of VEGF signaling...

This is the first report of using piggyback technique for the venous anastomosis in two pediatric recipients of small en bloc kidneys, which was found to be effective to avoid twisting of the grafts and vessels. The donors were aged 2 and 3 years with a body weight of 17 and 20 kg. The recipient age was 14 and 16 years with a body weight of 42 and 54 kg. The implantation was done extraperitoneally in the right iliac fossa. The donor's inferior vena cava was anastomosed to the recipient's distal caval vein side-to-side using 6-0 polydioxanone running suture as the piggyback technique, initially dealing with the short vena cava graft in the first case...

BACKGROUND: Mastering right hemicolectomy techniques using laparoscopy in colorectal cancer surgery is very difficult. Although the long-term prognosis of laparoscopic right hemicolectomy (LRH) and complete mesocolic excision is unquestionable, different surgeons have their own opinions on routes of conducting LRH. OBJECTIVES: LRH surgery is very complex due to the upper abdominal anatomical structure and vascular variation. Therefore, it has been considered the most difficult of all colorectal cancer surgeries...
