background: galantamine is a drug used for the treatment of alzheimer’s disease and some other cognitive disorders. it is an inhibitor of acetylcholinesterase however, interaction with nicotinic acetylcholine receptors has also been reported. owing to the significant role of cholinergic anti-inflammatory pathways in neuro-immunomodulation, we decided to examine the effect of galantamine on tula...

it is estimated that one third of the world's population is latently infected with tuberculosis (tb). the hiv epidemic fuels the tb epidemic by increasing the risk of reactivation of latent tb infection and by facilitating a more rapid progression of tb disease. although the incidence of tb is constant or decreasing in many regions of the world, rates remain high in developing countries as a co...

tetanus can be only prevented by vaccination because immunity against this disease is rarely acquired, even by natural infections. to maintain long-term protective immunity against tetanus, booster immunization is essential for adolescents and adults. most hospitalized cases and virtually all deaths occur in people over 60 years of age. the purpose of this study was to investigate the degree of...

neopterin, apyrazinopyrimidine compound, is produced by macrophages after induction by interferon gamma (ifn-y) and serves as a marker of cellular immune system activation followed by oxidative stress. the aim of this study was to determine urinary neopterin to creatinine ratio (uncr) as a surrogate marker of cell-mediated immune activation in multiple sclerosis (ms). three weekly early morning...

Particulate matter, such as diesel exhaust particles (DEPs), modulate adaptive immune responses in the lung; however, their mechanism of action remains largely unclear. Pulmonary dendritic cells (DCs) are crucial mediators in regulating immune responses. We hypothesized that the immunomodulatory effects of DEPs are caused by alteration of DC function. To test this, we instilled mice with DEPs a...

long-acting (depot) anti-psychotic injection (lai) is an essential component of the treatment of schizophrenia. in this editorial, the journal tries to give a short account of the current ideas and practical aspects of lai, with respect to the iranian experience. two categories of the long-acting injections are discussed mainly regarding their dosage, intervals of their injections and availabil...

The production of the type I antimicrobial peptide (AMP) subtilin by Bacillus subtilis is regulated in a cell-density-dependent manner [Kleerebezem M, de Vos WM, Kuipers OP. The lantibiotics nisin and subtilin act as extracellular regulators of their own biosynthesis. In: Dunny GM, Winans SC, editors. Cell-cell signaling in bacteria. Washington, D.C., USA: ASM Press; 1999. p. 159-74; Stein T, B...
