OBJECTIVE The aim of this study is to investigate the effects of three different intensities of infrared diode laser radiation on amino acid neurotransmitters in the cortex and hippocampus of rat brain. BACKGROUND DATA Lasers are known to induce different neurological effects such as pain relief, anesthesia, and neurosuppressive effects; however, the(More)
BACKGROUND AND OBJECTIVES Mobile phone radiation and health concerns have been raised, especially following the enormous increase in the use of wireless mobile telephony throughout the world. The present study aims to investigate the effect of one hour daily exposure to electromagnetic radiation (EMR) with frequency of 900 Mz (SAR 1.165 w/kg, power density(More)
The present study aims to investigate the effect of electromagnetic radiation (EMR) generated by mobile phones on the levels of amino acid neurotransmitters; glutamate, aspartate, GABA, glycine and taurine in the cortex of adult and young rats. Several studies showed that EMR could influence normal brain physiology, probably by changing cortical(More)
Effects of tranquilizing agents on neurotransmitters in the heart have not been widely studied. Thus, the effect of intraperitoneal injection of reserpine, (2.5 mg/kg bw) on the concentrations of excitatory (glutamic acid, glutamine, aspartic acid, asparagine), inhibitory (GABA, glycine, alanine, taurine), neurotransmitters as well as the enzymes (GOT and(More)
New cyanoacrylamide derivatives were theoretically examined for their binding abilities to a protein model of apoptosis inhibitor proteins x-IAP and c-IAP1 using molecular modeling. The two compounds 5a and 5b proved promising IAP antagonists, where they have good binding affinity toward the selected active domains. Anticancer activity of all derivatives(More)
Brain cooling has pronounced effects on seizures and epileptic activity. The aim of the present study is to evaluate the anticonvulsant effect of brain cooling on the oxidative stress and changes in Na+, K+-ATPase and acetylcholinesterase (AchE) activities during status epilepticus induced by pilocarpine in the hippocampus of adult male rat in comparison(More)
BACKGROUND The use of mobile phones is rapidly increasing all over the world. Few studies deal with the effect of electromagnetic radiation (EMR) on monoamine neurotransmitters in the different brain areas of adult rat. AIM The aim of the present study was to investigate the effect of EMR on the concentrations of dopamine (DA), norepinephrine (NE) and(More)
Type 2 diabetes mellitus is characterized by the deposition of islet amyloid polypeptide (IAPP) as amyloid in islets, a process thought to be toxic to β-cells. To determine the feasibility of targeting these aggregates therapeutically, we vaccinated transgenic (Tg) mice that overexpress human IAPP and were fed a high-fat diet to promote their diabetic(More)
