Acute rejection of a cryopreserved arterial homograft.

The use of arterial homograft is indicated especially in case of prosthetic graft infections after bypass surgery. We report the case of a patient who experienced the loss of a cryopreserved femoral artery caused by an acute rejection. This homograft had to be explanted 1 month after implantation because of an acute aneurysmal deterioration.

Gastrocele complicates the course of non-operated severe caustic injuries: operative strategies.

Background: For selected cases of severe caustic injuries, evidence favors conservative management, consisting of radiographic and clinical observation without emergency surgery. However, this approach can lead to the development of gastric distension caused by combined esophageal and antral strictures, called gastrocele. This study assessed the safety of a two-stage surgical treatment for gastrocele.

Compressive pancreaticoduodenal artery aneurysm associated with celiac artery stenosis.

Peripancreatic artery aneurysms are a rare condition, representing <2% of all splanchnic artery aneurysms, and have been significantly related to celiac axis stenosis. While they are most often asymptomatic, those aneurysms have a strong tendency to rupture (52% rupture rate at the initial presentation) and, in this case, the outcome is often dramatic. Given that reports of this disease are rare, appropriate guidelines are difficult to formulate and different treatment strategies have been proposed.

The conservative management of severe caustic gastric injuries.

Objective: To determine the safety of a conservative approach to treating severe caustic injury in patients lacking clinical and biochemical signs of transmural necrosis.

Background: Esophagogastrectomy is thought to limit the progression of severe caustic injury in the upper gastrointestinal tract observed upon initial endoscopic examination. However, endoscopic evaluation of the depth and spread of necrosis is challenging and may lead to unnecessary gastrectomy.

Management of isolated spontaneous dissection of superior mesenteric artery.

Purpose: Our objectives were to clarify the management of isolated spontaneous dissection of the superior mesenteric artery (DSMA).

Methods: We reviewed seven patients diagnosed as having DSMA from 2002 to 2007 (group A). Simultaneously, we analyzed 50 cases of DSMA previously reported in the literature between 2000 and 2008 (group B).

Inhibition of tissue factor-factor VIIa proteolytic activity blunts hepatic metastasis in colorectal cancer.

Background: Expression of the principal initiator of coagulation, tissue factor (TF), by colorectal cancer (CRC) cells is involved in tumoral angiogenesis and metastasis progression, after binding of factor VIIa (FVIIa) to TF and generation of TF-FVIIa activity. We thus hypothesized that inhibition of the TF pathway by active site-blocked FVIIa (FFR-FVIIa) may prevent the development of hepatic metastasis in CRC.

Methods: Rat tumoral cells (DHDK12 proB cells) expressing high levels of TF were injected in the portal vein in syngenic BDIX rats.

A comparative study of sex pheromone reception in the Hadeninae (Lepidoptera: Noctuidae).

A comparative study of the olfactory responses to pheromone compounds was performed in twenty-four species of Hadeninae. Electroantennograms (EAG) were recorded on male moths in response to thirty compounds and the response profiles of each species were analysed by factorial correspondence analysis. A limited number of molecules were found active and the most effective stimuli were Z9 tetradecenes and Z11 hexadecenes.
