objective: dendritic cells (dcs) play a critical role in the beginning and in the course of immune responses. by observing. considering the defect in these cells in patients with tumor malignancy. in recent years there has been considerable interests in correction and use of these cells. in our prvious studies we showed that lysate of listeria monocytogenese can induce maturation of dendritic c...

  In this study we investigated the bronchodilatory and anticholinergic effects of the aqueous extract (AE), brewed extract (BE) and ethanol extract (EE) of Polygonum avicular in comparison with saline (S) on isolated tracheal chains of the guinea pig. Due to the probable confounding effect of ethanol in the EE, the effects of this extract were also compared with 96 % ethanol. None of the plant...

the mössbauer spectra of nanoferrite materials such as ni0.25mn0.75fe2o4, co0.5mn0.5fe2o4 and ni0.4co0.6fe2o4 have been reported and the above materials were prepared by sol-gel combustion method using metal nitrates as source material and polyvinyl alcohol(pva) as agglomeration reducing agent. as the structural, thermal and magnetic properties (vsm) of the above ferrites have been published al...

Editor’s Note: This article is part of a series that describes the many ways that the Department of Health & Human Services (DHHS) interacts with the emergency care system. DHHS includes many divisions that are well known to the health care world including the Center for Medicare & Medicaid Services, the Health Resources and Services Administration, the National Institutes of Health, and the Ag...

Simultaneous laser induced- breakdown spectroscopy (LIBS) and acoustic response techniques as well as Laser induced fluorescence (LIF) are applied to investigate the abnormal lymph tissues due to Hodgkin disease. The spectral shift in the emissive fluorescence of the cancerous tissues has been observed respect to the normal ones. Regarding LIBS, the concentrations of Ca and Na trace elements ha...
