lead is a common toxic agent which impairs various organs functions of the body. the basis of this toxicity is believed to be the negative influence on enzymatic system of cells. in the past few years, increasing consideration has been given to interactions occurring between lead and some essential metals including se and zn. based on the finding that some trace elements could reverse the toxic...

it is an intensive 1-day course for introducing utilizing transcranial direct current stimulation (tdcs) in an applied format. this technique is a noninvasive brain stimulation that uses direct electrical currents over the head to stimulate specific parts of the brain which modulates neuronal activity. it has strong potentiality in the field of medical and neuroscientific research. anodal stimu...

background: non-steroidal anti-inflammatory drugs (nsaid) have been associated with antioxidant property and have been shown to improve the circulating antioxidant status on daily dosing in different inflammatory conditions. the present study was conducted to investigate the antioxidant role of meloxicam in aluminum induced oxidative stress in rat brain. methods: in the in vivo experiments, spr...

Introduction: Nitric oxide seems to play a dual role in ischemia/reperfusion injury. Few studies have investigated whether it exacerbates or improves brain edema. In the present study, we inhibited the activity of nitric oxide synthase by L-NAME and evaluated the cerebral infarct volume, tissue swelling and brain edema, alongside the measurement of blood flow of the ischemic region. Methods...

Introduction: Neuromyelitis Optica (NMO) is a rare inflammatory disease of the central nervous system which generally affecting the spinal cord and optic nerve. Damage to the optic nerve can result in the patient's dim vision or even blindness, while the spinal cord damage may lead to sensory and motor paralysis and the weakness of the lower limbs in the patient. Magnetic Reson...

Introduction: Research evidence indicates that maladaptive reorganization of the brain plays a critical role in amplifying pain experiences and pain chronification; there is, however, no clear evidence of change in brain wave activity among patients with chronic low back pain (CLBP). The objective of this study was to assess brain wave activity in patients with CLBP, compared to healthy control...
