Introduction Arterial spin labeling (ASL) utilizes the water in arterial blood as endogenous contrast agent to assess cerebral blood perfusion and therefore is becoming more commonly used. A perfusion image is generated by subtracting a tagged image from a control image, where the tagged image is acquired following the “labeling” of the blood upstream using an inversion pulse. The time delay be...

The steady-state distribution of endogenous albumin in mouse diaphragm was determined by quantitative postembedding protein A-gold immunocytochemistry using a specific anti-mouse albumin antibody. Labeling density was recorded over vascular lumen, endothelium, junctions, and subendothelial space. At equilibrium, the volume density of interstitial albumin was 18% of that in circulation. Despite ...

Background: Chemotherapy or irradiation is associated with impaired fertility. The aim of this study was to investigate the possible protective role of testosterone enanthate (TE) on the proliferative activity, plasma testosterone level and morphometry of epithelial cells of seminal vesicles in busulfan-induced spermiotoxicity. Materials and Methods: Sprague- Dawley rats were divided into 4 gro...

There are various situations in which it is desirable to separate bioparticles, such as DNA, viruses, bacterial or mammalian cells from background [1]. Here, we focus on the isolation of rare mammalian cells, from cell mixtures or body fluids for cancer detection and individualized medicine using electrophoresis (DEP) [2]. Isolating rare cells is challenging, mostly due to their low number comp...

introduction: in some intoxicated patients, cerebrospinal fluid (csf) is examined due to the prolonged loss of consciousness, focal neurologic findings, and fever of unknown origin. we aimed to evaluate the probable relationship between the different toxicity causes and the csf indices in poisoned patients and determine if they could predict the patients’ outcome. methods: all patients who had ...

background: invasive fungal infections (ifis) are chief infectious complications in patients undergoing hematopoietic stem cell transplantation (hsct). however, the diagnosis of fungal infections is difficult, and often empiric treatment initiates. since there is no data available on the prevalence of antifungal drugs administration in allogeneic hsct recipients in iran, we decided to conduct t...

allogeneic hematopoietic stem cell transplantation is used in the treatment of patients suffering from hematologic and non-hematologic disorders, but the application is limited by the identification of a suitable donor. umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell (hsc) transplantation. despite all advantages, the limited cell dose is one of the  major obstacle...

background: people who use home blood glucose monitors may use their mobile phones in the close vicinity of medical devices. this study is aimed at investigating the effect of the signal strength of 900 mhz gsm mobile phones on the accuracy of home blood glucose monitors. methods: sixty non-diabetic volunteer individuals aged 21 - 28 years participated in this study. blood samples were analyzed...
