Shock is accompanied by generalised splanchnic hypoperfusion, and splanchnic organs like the pancreas can be damaged, as shown in animal experimental models and in humans, by the presence of high plasma concentrations of trypsin and other pancreatic enzymes. In order to design a radioimmunoassay technique (RIA) for the measurement of equine trypsin-like immunoreactivity (TLI) in biological flui...

Allogeneic bone marrow transplantation is a curative treatment for leukemia and lymphoma, but graft-vs-host disease (GVHD) remains a major complication. Using a GVHD protective nonmyeloablative conditioning regimen of total lymphoid irradiation and antithymocyte serum (TLI/ATS) in mice that has been recently adapted to clinical studies, we show that regulatory host NKT cells prevent the expansi...

/V-Nitniso-.V-methyhirea (NMU) is an effective carcinogen for the induction of mammary carcinoma in the rat. Tamoxifen (TAM), used as a chemopreventive agent to reduce tumor incidence, has been well studied using this model. We have utilized the rat mammary carcinoma model to assess the effect of TAM on preneoplastic changes. Fifty-day-old virgin female Sprague-Dawley rats were randomized by we...

The Competitive State Anxiety Inventory-2 Revised (CSAI-2R), is one of the most frequently used instruments in the evaluation of situational anxiety in sports competition. Objectives: The objective of this study was to validate the Tunisian version based on the French version of the Competitive State Anxiety Inventory-2 Revised (CSAI-2R), including the direction and the frequency scales. Method...

Quantitative computerized Western blot analysis of antibody responses during experimental canine Leishmania infantum infection distinguished between immunodominant and nonimmunodominant protein bands. Six infected beagles, positive by both PCR and parasite culture, were monitored over 75 weeks postinfection and during a 12-week allopurinol treatment course. All dogs were symptomatic at the time...

OBJECTIVE A study was run to test which of five electroencephalographic (EEG) indices was most diagnostic of loss of vigilance at two levels of workload. BACKGROUND EEG indices of alertness include conventional spectral power measures as well as indices combining measures from multiple frequency bands, such as the Task Load Index (TLI) and the Engagement Index (El). However, it is unclear whi...

During an 8-year period, 28 young adults (median age 27 years) and 30 children (median age 10 years) with severe aplastic anemia have received allogeneic bone marrow transplantation (BMT) from major histocompatibility locimatched sibling donors after preparation with cyclophosphamide and total lymphoid irradiation (TLI). All recipients were previously transfused. Comparison of post-bone marrow ...

Hypoxia-inducible factor 1α (HIF-1α) is an important transcription factor in mediating oxygen homeostasis that can regulate vascular endothelial growth factor (VEGF) gene transcription. HIF-1α can induce neovascularization in ischemic injury. This research observed HIF-1α and VEGF expression in traumatic lung injury (TLI) to discuss their correlation. Healthy male SD rats at 7-week old were ran...
