we studied the immune system, especially the chemotactic activity of neutrophils, in ten patients with vitamin d-deficient rickets and compared the results with ten healthy controls of matched age. among all immune system factors, the chemotactic studies persistantly showed remarkable deficiency in leukocyte mobility, both random motion and migration. when compared with controls, the findings w...

background: lippia citriodora kunth is one of the iranian traditional medicines for the treatment of convulsive disorders. the goal of this study is to investigate the anticonvulsant activity of the plant’s leave ethanolic extract against electro‑ and chemoconvulsant‑induced seizures in mice. methods: the anticonvulsant activity of the extract (200, 400, 800 mg/kg, per os, p.o.) was investigate...

the occurrence of antibiotic-resistant pathogenic bacteria is becoming a serious problem. the rise of multiresistance strains has forced the pharmaceutical industry to come up with new generation of more effective and potent antibiotics, therefore creating development of antivirulence compounds. due to extensive usage of cell-to-cell bacterial communication (qs) systems to monitor the productio...

Air pollution is the most important environmental problem of last century that threatens the health of living organisms, especially plants. SO2 is one of the main air pollutants that can cause to imbalance in growth and physiological function of plant in high concentrations. Symbiosis of Rhizobium bacteria with alfalfa can cause increasing plant growth and plant resistance to abiotic stresses. ...

One of the important issues in designing a brain-computer interface system is to select the type of mental activity to be imagined. In some of these systems, mental activity varies with user intent and action that must be controlled by the brain-computer system, and in a number of other signals, the received signals contain the same activity-related mental activity that should be performed by t...

epilepsy is accompanied with a strong change in neuronal activity not only in excitatory (glutamatergic) and inhibitory (gabaergic) neurotransmission, but also in neuromodulatory agents. dopaminergic system, as an important neuromodulatory system of the brain, has significant effect on neuronal excitability. in addition, this system undergoes many changes in epileptic brain. understanding the e...

Prevention of malignant disease such as cancer is obviously much more important than therapy, so primary prevention tactics should be invoked with the greatest possible effort. Because delaying a disease such as cancer is somehow equivalent to cure and it is now generally accepted that cancer can be managed through chemopreventive interventions. Since a considerable number of known cancer chemo...
