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)
Early detection of blind children at the household and community level is critical in reducing the global burden of visual impairment and childhood blindness. The aim of the study is to identify a range of potential issues relating to parental awareness and perceptions of common eye diseases affecting children. It was a descriptive and cross sectional(More)
OBJECTIVES The present study aimed to determine the prevalence and etiology of erectile dysfunction in Saudi type 2 diabetic patients. PATIENTS AND METHODS 429 Saudi type 2 diabetic male patients aged more than 30 years were recruited. Total and bio-available serum testosterone, sex hormone binding globulin and free testosterone levels were measured by(More)
Electromagnetic radiation (EMR) of cellular phones may affect biological systems by increasing free radicals and changing the antioxidant defense systems of tissues, eventually leading to oxidative stress. Green tea has recently attracted significant attention due to its health benefits in a variety of disorders, ranging from cancer to weight loss. Thus,(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)
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)
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)
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)
The principal objective of this study was to determine the modifications induced by the synthetic pyrethroid insecticide cyfluthrin in the concentrations of dopamine (DA), norepinephrine (NE) and epinephrine(E) in selected brain and spinal cord regions of male albino rats. A group of 30 rats were injected intraperitoneally every other day with cyfluthrin at(More)
