We examined the effects of the developmental milieu on the capacity of B cells to undergo immune response gene-controlled, T cell-dependent polyclonal proliferation. Although I-Aq poly(Glu60 Ala30 Tyr10)n (GAT)-nonresponder T cells developing in a responder environment become phenotypic GAT-responders, I-Aq B cells remain unresponsive to GAT, even after maturation in a GAT-responder animal. Con...

objective: the use of hema as a biocompatible material in dentin bonding systems and its potential for clinical applications has been well established. excess water can affect conversion of bonding resins. the aim of this study was to survey the effect of water on the degree of conversion of hema by fourier transform infra-red spectroscopy (ft-ir). materials and methods: in this experimental st...

Nanobiotechnology is the assembling of biological molecules into nanodimension complexes. This has been used for the preparation of polyhemoglobin formed by the assembling of hemoglobin molecules into a soluble nanodimension complex. New generations of this approach include the nanobiotechnological assembly of hemoglobin, catalase, and superoxide dismutase into a soluble nanodimension complex. ...

SUDDEN CARDIAC ARREST IS THE most common lethal consequence of cardiovascular disease. Even if return of spontaneous circulation (ROSC) from cardiac arrest is achieved, approximately 60% of patients will not survive to hospital discharge. The high mortality is attributed to the postcardiac arrest syndrome, which involves global ischemiareperfusion injury, myocardial stunning, and anoxic brain i...

the southeastern part of turkey is quite rich, fertile and mature in terms of hydrocarbonseepages. while the use of the related sources meet the energy demand, it damages the environment and humanhealth. in this study, several geochemical methods were applied to analyze the hydrocarbon sepage samplesobtained from seven towns in the province of adiyaman where is very close to the oil production ...

Purpose: To evaluate the protective effect, effective time window, and mechanism of protection sevoflurane post-conditioning late on heart muscle ischemiareperfusion (I/R) lesion in isolated rat heart.Methods: Langendorff perfusion model was established Sprague-Dawley (SD) rats. After 15 min stabilization, rats were assigned to 10 groups, based treatments given: control group (TTC), I/R group, ...

In emergency and critical care medicine, lung ischemia-reperfusion injury is a prevalent disorder, which has significant morbidity mortality. However, there still lack of effective means to block the injury. Established model mice; histological analysis scoring were helpful assess pathological in tissue; using an enzymelinked immunosorbent assay kit, expressed interleukin-6 interleukin-1 bronch...
