background: reversal of tubal ligation is requested by some women for various reasons. the present study aims to determine the rate of pregnancy after tubal ligation reversal. case: in these case series, we reported fifteen women who requested tuboplasty after tubal ligation. in these cases reversal of tubal ligation was done in 15 women. pregnancy occurred in 4 women (26.6%). two term pregnanc...

popliteal artery injuries are mainly seen in military experience. this study was undertaken in a civilian vascular surgical unit with a large trauma workload dealing with traffic accidents. a retrospective review of patients treated between 1995 and 2001 was undertaken. 145 cases of popliteal artery injuries were treated. these cases included 46.89% compound and lacerated injuries due to traffi...

bile duct ligation (bdl) is shown to induce cholestasis-related liver function impairments as well as consequent cognitive dysfunctions (i.e. impaired learning and memory formation). this study investigates the effects of cholestasis (14, 21 and 28 days post bile duct ligation) on spatial and non-spatial novelty detection, using a non-associative task. male mice weighing 30-35 g were used. chol...

Pericardial patches are commonly used during cardiovascular surgery to close blood vessels. In arteries, patches accumulate arterial progenitor cells; we hypothesized that venous patches would accumulate venous progenitor cells, in the absence of arterial pressure. We developed a novel rat inferior vena cava (IVC) venotomy model and repaired it with a pericardial patch. Cells infiltrated the pa...

Arterial occlusive diseases are major causes of morbidity and mortality. Blood flow to the affected tissue must be restored quickly if viability and function are to be preserved. We report that disruption of the mixed-lineage protein kinase (MLK) - cJun NH2-terminal kinase (JNK) signaling pathway in endothelial cells causes severe blockade of blood flow and failure to recover in the murine femo...

Rationale: Understanding the mechanisms that regulate arterial flow recovery is important to design treatment options for peripheral artery disease patients ineligible invasive revascularization. Transcriptional orchestrators of this process represent an appealing target design. We previously identified Prdm (positive regulatory domain-containing protein) 16 as arterial-specific endothelial tra...

BACKGROUND Thrombotic vascular occlusion is one of the main complications that can occur during microsurgical anastomosis and is frequent when the blood becomes turbulent. The aim of this ex vivo study was to test the use of nonlinear mathematical tools to detect turbulence flow upstream and downstream of an arterial stenosis and of a microsurgical anastomosis technique in arteries with diamete...

Air embolization of the brain produces cerebral ischemia that can be focal and reversible. The method has previously been hampered by (1) lack of selective arterial injection of the embolus, (2) disruption of local hemodynamic relationships by ligation of major arterial channels, (3) excessive volume of the air embolus, and (4) uncontrolled bubble size. To minimize these factors, a technique wa...
