Anti-apoptotic properties of physiological and elevated levels of the cellular prion protein (PrP(c)) under stress conditions are well documented. Yet, detrimental effects of elevated PrP(c) levels under stress conditions, such as exposure to staurosporine (STS) have also been described. In the present study, we focused on discerning early apoptotic STS-induced proteome and phospho-proteome changes in SH-SY5Y human neuroblastoma cells stably transfected either with an empty or PRNP-containing vector, expressing physiological or supraphysiological levels of PrP(c), respectively...

The genus Anthopsis was introduced for a black fungus with peculiar, inverted phialides and triangular conidia. The genus accommodates, in addition to the type species Anthopsis deltoidea, which once was reported as a cause of human phaeohyphomycosis, two further taxa: A. catenata and A. microspora. Current taxonomy is mainly based on microscopic structures of phialides. To assess the phylogenetic position of the genus, sequences of the internal transcribed spacer region and partial LSU rDNA were obtained for Anthopsis spp...

Mobilized PBSC are the main source for allogeneic HSCT. We aimed to evaluate factors that affect CD34+ cell yield including the donor's age, gender, BSA, processed blood volume and the method of G-CSF dose calculation. Data from 170 healthy donors were analyzed. The concentration of CD34+ cells in the peripheral blood (PB) and the processed volume of blood were significantly correlated to CD34+ cells yield (P < .00005 and P < .001, respectively). The G-CSF dose per m(2) was significantly correlated to the concentration of CD34+ cells in the PB (P = ...

OBJECTIVE: The aim of this study was to compare the TNM staging system and the American Thyroid Association (ATA) recurrence risk classification in predicting radioiodine refractory disease (RRD) in differentiated thyroid cancer (DTC) and to analyze the correlation of stimulated thyroglobulin (Tg) levels and rate of Tg elevation with the standardized uptake value on (18)F-fludeoxyglucose (FDG) PET/CT scan. METHODS: RRD was indicated through the retrospective analysis of consecutive (18)F-FDG PET/CT scans in DTC with stimulated Tg >10 ng/ml and negative (131)I NaI whole-body scans (WBS)...

BACKGROUND: Although a clear mechanism underlying the pathophysiology of schizophrenia (SZ) remains elusive, oxidative stress, inflammatory syndrome and immune activation have become an attractive hypothesis for explaining the pathophysiology of SZ. Data from prior studies on the role of matrix metalloproteinase 9 (MMP-9) and brain-derived neurotrophic factor (BDNF) single nucleotide polymorphisms (SNPs) in SZ are contradictory. We aimed to investigate whether oxidative stress, inflammatory and immune activation markers as well as MMP-9 levels may be implicated in SZ pathogenesis...

BACKGROUND: The present research was carried out to investigate pharmacological properties of Buxus papillosa C.K. Schneid. (Buxaceae). METHODS: Buxus papillosa extracts of leaves (BpL), stem (BpS), roots (BpR) and BpL fractions: hexane (BpL-H), aqueous (BpL-A) also plant constituent, cyclomicrobuxine effect were studied in jejunum, atria, aorta and tracheal preparations from rabbit and guine-peg. RESULTS: Ca(++) antagonistic effect of BpS, BpR, BpL-H, BpL-A and cyclomicrobuxine were conclusively suggested, when spontaneous contractions of rabbit jejunal preparation was relaxed along with subsequent relaxation of potassium chloride (80 mM) induced contractions...

BACKGROUND: Efforts are underway to eliminate trachoma as a public health problem by 2020. Programmatic guidelines are based on clinical signs that correlate poorly with Chlamydia trachomatis (Ct) infection in post-treatment and low-endemicity settings. Age-specific seroprevalence of anti Ct Pgp3 antibodies has been proposed as an alternative indicator of the need for intervention. To standardise the use of these tools, it is necessary to develop an analytical approach that performs reproducibly both within and between studies...

PURPOSE: To determine the demographic and refractive characteristics of excimer laser refractive surgery candidates in Iran. METHODS: This was a cross-sectional study between 2010 and 2014. All information was collected from 28 centers randomly selected from 12 provinces. Then, for each season of the year, one week was chosen through simple random selection, and within each week, 3 days were again chosen randomly. All excimer laser surgical procedures performed during these 3 days were identified by training staff, and data were extracted from patient charts...

Improved models of the gastrointestinal environment have great potential to assist the complex process of drug formulation. Molecular dynamics (MD) is a powerful method for investigating phase behaviour at a molecular level. In this study we use multiple MD simulations to calculate phase diagrams for bile before and after digestion. In these computational models, undigested bile is represented by mixtures of palmitoyl-oleoylphosphatidylcholine (POPC), sodium glycodeoxycholate (GDX) and water. Digested bile is modelled using a 1:1 mixture of oleic acid and palmitoylphosphatidylcholine (lyso-phosphatidylcholine, LPC), GDX and water...

A reduced graphene oxide/bismuth (rGO/Bi) composite was synthesized for the first time using a polyol process at a low reaction temperature and with a short reaction time (60 °C and 3 hours, respectively). The as-prepared sample is structured with 20-50 nm diameter bismuth particles distributed on the rGO sheets. The rGO/Bi composite displays a combination of capacitive and battery-like charge storage, achieving a specific capacity value of 773 C g(-1) at a current density of 0.2 A g(-1) when charged to 1 V...

Salinity stress is the most important and common environmental stresses throughout the world, including Iran. The aim of this study was to investigate the expression of several important genes involved in the salinity tolerance of the rice cultivars differing in salt sensitivity. In this research, the expression of four mitochondrial genes, H2O2, malondialdehyde (MDA), proline, sodium, potassium and superoxide dismutase (SOD), was measured in Iranian rice cultivars and two well-known international varieties as checks in response to 100 mM salt stress...

HIV-1 envelope (env) glycoprotein mediates an important role in entry of the virus into the susceptible target cells. As env glycoprotein of HIV-1 is highly variable in the different geographical regions, in the present study, different properties of this protein in Iran are compared with five nearby countries. The sequences of HIV-1 env glycoproteins of Iran, Afghanistan, Russia, Turkey, Pakistan and Saudi Arabia databases were collected from databases. Amino acid composition and physical and chemical properties of the proteins from these countries were studied using Protparam and COPid tools...

Aims: To examine the regulation of SREBP-1c and CAV1 by microRNA-29a (miR-29a) in cells infected with hepatitis C virus (HCV) in an attempt to control HCV-induced non-alcoholic fatty liver disease. Methods: In order to examine the manipulation of SREBP-1c and CAV1 by miR-29a, oleic acid (OA)-treated JFH-I-infected Huh-7 cells were used. OA was added 24 h post-transfection and gene expression was investigated by qRT-PCR at 48 h post treatment. The functional impact of the observed alteration in SREBP-1c and CAV1 expression was analyzed by examining lipid droplet (LD) and triglyceride (TG) content at 72 h post-OA treatment using light microscopy and spectrophotometry, respectively...

BACKGROUND: Toxoplasma gondii is the most common parasite causing latent cerebral infections in human. It has been shown that some anti-psychotic drugs are able to inhibit the proliferation of the parasite in in vitro study. There is very limited data regarding the inhibitory effect of anti-psychotics on Toxoplasma in in vivo. In this study, we evaluated anti-Toxoplasma activity of fluphenazine and thioridazine drugs on T. gondii in mice. METHODS: Mice were divided into six groups: Control, sesame as vehicle, thioridazine 10 mg/kg, thioridazine 20 mg/kg, fluphenazine 0...

REVIEW
Elham Z Movassagh, Hassan Vatanparast
Nutrition is an important modifiable factor that affects bone health. Diet is a complex mixture of nutrients and foods that correlate or interact with each other. Dietary pattern approaches take into account contributions from various aspects of diet. Findings from dietary pattern studies could complement those from single-nutrient and food studies on bone health. In this study we aimed to conduct a scoping review of the literature that assessed the impact of dietary patterns (derived with the use of both a priori and data-driven approaches) on bone outcomes, including bone mineral status, bone biomarkers, osteoporosis, and fracture risk...
