objective(s):long-term treatment with antipsychotics causes serious side effects such as tardive dyskinesia that characterized by abnormal movements in the orofacial region. oxidative stress in the brain specific area is implicated in the pathophysiology of tardive dyskinesia. in this study the protective effect of crocin on haloperidol-induced orofacial dyskinesia was evaluated. materials and ...

achillea wilhelmsii have been used in folk remedies. the relaxant effects of the extractof a. wilhelmsii on tracheal chains of guinea pigs were examined. the relaxant effects offour cumulative concentrations of the extract, theophylline and saline were examined bytheir relaxant effects on precontracted tracheal chains of guinea pig by kcl (group 1), 10 μmmethacholine (group 2), incubated tissue...

We consider systems of two free particles in de Sitter invariant quantum theory and calculate the mean value of the mass operator for such systems. It is shown that, in addition to the well known relativistic contribution (and de Sitter antigravity which is small when the de Sitter radius is large), there also exists a contribution caused by the fact that certain decomposition coefficients have...

Cell-cell interaction is a basic topic in biological sciences. In embryogenesis, a largely unsolved problem is the means by which cell-cell recognition, necessary for the build up of a normal tissue, is mediated (1). Under pathological conditions this hitherto unrevealed mechanism of physiological interactions seems to be lost. In immunology numerous phenomena are based on cell-cell interaction...

Recent developments in physics and astrophysics lead us to introduce a new tired-light mechanism involving an interaction between a massive photon and Dirac's vacuum particles. 1. Tired-light mechanisms appeared in the literature as early as the late twenties, when Zwicky (1929), disturbed by the large values of the apparent recession velocities of galaxies, conceived a mechanism whereby photon...
