introduction: it has been reported that traumas such as transverse abdominal incision before myocardial ischemia result in a significantly decreased infarct size. this phenomenon is named remote preconditioning of trauma. since small skin burn is one of most common traumas, the effect of this injury on ischemia-induced arrhythmias and infarct size was investigated in a rat model of ischemia-rep...

objective: the aim of the present study is assessment of insulin resistance (ir) in obese women by tyg-index and compared with the homa-ir index. materials and methods: this cross-sectional study was performed on 61 obese women aged 18-45 years. weights, height, waist circumference (wc) were measured and body mass index (bmi) was calculated and recorded. a sample of fasting serum was collected ...

The application of IR 786 perchlorate (IR-786) as a selective optical sensor for cyanide anion in both organic solution (acetonitrile (MeCN), 100%) and solvent-free solid surfaces was demonstrated. In MeCN, IR-786 was selective to two anions in the following order: CN(-) > OH(-). A significant change in the characteristic dark green color of IR-786 in MeCN to yellow was observed as a result of ...

The proliferative responses of T cells, depleted of alloreactive cells, were tested upon stimulation by antigens presented on allogeneic antigen-presenting cells (APC). Restriction molecules involved in these responses were identified by inhibition of T cell proliferation with monoclonal antibodies against A(A alpha A beta) and E(E alpha E beta) molecules of the APC. The responses to all three ...

The incidence and severity of primary cardiac events are inversely related to the plasma concentration of high-density lipoproteins (HDLs). We investigated whether HDLs may exert a direct cardioprotection in buffer-perfused isolated rat hearts, which underwent a 20-minute low-flow ischemia followed by a 30-minute reperfusion. The administration of HDLs at physiological concentrations (0.5 and 1...

Immune response (Ir) gene products control immunologic function at several critical sites. We administered in vivo a monoclonal antibody reactive with I-Ak to F1 mice with the genotype H-2k/b. These treated mnice made a markedly reduced antibody response to antigen (H,G)-A--L, under the control of I-Ak, but not to antigen (T,G)-A--L, under the control of I-Ab. This relative specificity was lost...
