This study was aimed to evaluate the image quality and lacunar lesion detection of thin-slice brain computed tomography (CT) images with different reconstruction algorithms, including filtered back projection (FBP), hybrid iterative reconstruction (HIR), and iterative model reconstruction (IMR) by comparison of routine slice images with FBP reconstruction. Sixty-one patients underwent noncontra...

The unilateral or bilateral lesion of the Substantia nigra pars compacta (SNc) by chemical neurotoxins such as 6-hydroxy dopamine (6-OHDA) or 1- Methyl-4- phenyl -1,2,3,6 – tetirahydro pyridine (MPTP) are the most commonly and the main used methods for generating the animal models of Parkinson’s disease (PD). But these agents are expensive, dangerous, difficult to use and inacce...

PURPOSE Fluorine-18-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) and diffusion-weighted magnetic resonance imaging (DWI) share the same role in clinical oncology and it is feasible to obtain the standardized uptake value (SUV) and apparent diffusion coefficient (ADC) simultaneously by emerging the hybrid positron emission tomography/magnetic resonance (PET/MR). This study i...

hbme-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. the antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. hbme-l has also been reported to strongly and uniformly stain papillary and fo...

background: leishmaniasis is a worldwide disease prevalent in tropical and sub- tropical countries in the world. characterization of inflammatory responses produced in cutaneous leishmaniasis has not yet been completed. methods: the specific primers were designed for ten pro-inflammatory genes including ccl4, ccl3, tnf-α, il-1α, il-12p35, il-12p40, ccl5, ccr5, il-1β and ifn- γ and their express...

abstract objective : in this study, we have undertaken efforts to ascertain the anticancer potency of s. crispus (sc) extract on diethylnitrosamine (den) and acetylaminofluorene (aaf) induced hcc with special attention to hepatic drug metabolism and to investigate the effect of sc on preneoplastic marker enzyme activity specifically of microsomal aniline hydroxylase (ah) activity and lesion sco...

the onset of infections by leishmania parasites mainly caused by amastigote growth inside the macrophages. one of the important properties of lesion-derived amastigote is thought to be the attachment of various host proteins including immunoglobulins on the surface of amastigote. in this study, the presence of immunoglobulins on the surface of lesion-derived amastigotes was detected by western ...

introduction: the role of midbrain reticular formation, which includes the nucleus cuneiformis (ncf), as a crucial antinociceptive region in descending pain modulation has long been investigated. in this study, we tried to highlight the role of ncf in morphine-induced antinociception in formalin-induced pain model in rats. methods: a total of 201 male wistar rats weighing 260-310 g were used in...

introduction: a hydatid cyst of the head and neck is a very rare condition, even in areas where echinococcus infestation is endemic.   case report: we report a rare case of primary hydatid cyst of the right maxillary sinus in a 40-year-old man. the initial diagnosis of the presence of a cystic mass was the result of physical examination and computed tomography (ct) scan. we resected the cystic ...

in order to investigate effect of application of nitroxin and nitrogen chemical fertilizer on yield and yield components, split plot experiment on the basis of randomized complete block design with four replications was conducted. four levels of nitrogen fertilizer (n1: 100% chemical fertilizer, n2: 75% chemical fertilizer + 100% biological fertilizer, n3: 50% chemical fertilizer + 100% biologi...
