Nanoformulations derived from fine porous ZnO quantum dot nanoparticles (QD NPs) can offer strong potential medical applications; especially in cancer therapy. ZnO QD NPs was synthesized by sol-gel hydrothermal process, fast cold quenching and further smart surface functionalization methods to obtain ultrasmall size (1-4 nm) NPs. ZnO nanopolymer, a wetting agent, PEG co-solvent and water/oil emulsion stabilizer were considered in our nanofluid formulation. The resulting nanofluid was characterized by SEM, FTIR, photoluminescence, band gap energy, zeta potential and UV-Vis spectroscopy...

BACKGROUND AND PURPOSE: Despite recent declines in stroke mortality in high-income countries, the incidence and mortality of stroke have increased in many low- and middle-income countries. Population-based information on stroke in such countries is a research priority to address this rising trend. This study was designed to evaluate 5-year stroke mortality and its associated factors. METHODS: During a 12-month period beginning from November 2006, 624 patients with first-ever stroke (FES) living in Mashhad, Iran, were recruited and followed longitudinally...

The aim of the present study was to investigate the effects of single or combined administration of dietary fermentable fiber (Vitacel® ) and probiotic PrimaLac® on mucosal immune parameters, digestive enzyme activity, gut microbiota and growth performance of Caspian white fish (Rutilus frisii kutum) fingerlings. Fish were transferred to laboratory, acclimatized for two weeks and then fish (0.56 ± 0.026 g) were allocated into 12 tanks (30 fish per tank). Triplicate groups were fed a basal diet (Control) or basal diet supplemented with fermentable fiber [Vitacel® ] (FF), probiotic [PrimaLac® ] (P) and combined fermentable fiber and probiotic (FF + P)...

INTRODUCTION: Studies about globalization and internationalization demonstrate different attitudes in explaining these concepts. Since there is no consensus among Iranian specialists about these concepts, the purpose of this study is to explain the concepts of internationalization and globalization in Iran. MATERIALS AND METHODS: This study is a systematic review done in the first half of 2016. To explain the concept of globalization and internationalization, articles in Scientific Information D atabase, Magiran database, and Google Scholar were searched with the keywords such as globalization, scientific exchange, international cooperation, curriculum exchange, student exchange, faculty exchange, multinational cooperation, transnational cooperation, and collaborative research...

Essentials Heparin-binding site (HBS) variants of antithrombin (AT) are associated with thrombosis risk. HSB variants have, in general, normal progressive inhibitory activity but reduced heparin affinity. Thrombosis in HSB carriers has been primarily attributed to the loss of heparin cofactor activity. Results here demonstrate that HSB variants of AT also lack anti-inflammatory signaling functions. SUMMARY: Background Several heparin-binding site (HBS) variants of antithrombin (AT) have been identified that predispose carriers to a higher incidence of thrombosis...

Background: To assess the clinical consequences of AcrySof toric intraocular lens (IOL) and Hoya toric IOL implantation to correct preexisting corneal astigmatism in patients undergoing cataract surgery. Materials and Methods: In this study, we examined 55 eyes of 45 patients with at least 1.00 D corneal astigmatism who were scheduled for cataract surgery. After phacoemulsification, toric IOL was inserted and axis was aligned. We observed the patients, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), keratometry, manifest refraction, and IOL axis alignment 6 months after surgery...

The sonocatalytic performance of CeO2 nanoparticles synthesized by a hydrothermal method (CeO2 -H) and CeO2 @biochar (CeO2 -H@BC) nanocomposite, were evaluated for the degradation of Reactive Red 84 (RR84) under ultrasonic irradiation. For comparison purposes the corresponding performance of bare biochar (BC) and commercial CeO2 (CeO2 -C) samples were also assessed. A complementary characterization study, involving scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Transmission electron microscopy (TEM), dynamic light scattering (DLS), X-ray diffraction (XRD), N2 adsorption at -196°C (Brunauer-Emmett-Teller (BET) method) and Fourier transform infrared spectroscopy (FT-IR) was undertaken to gain insight into the structure-performance relationships...

PURPOSE: Noonan Syndrome (NS) is an autosomal dominant disorder with many variable and heterogeneous conditions. The genetic basis for 20-30% of cases is still unknown. This study evaluates Iranian Noonan patients both clinically and genetically for the first time. MATERIALS/METHODS: Mutational analysis of PTPN11 gene was performed in 15 Iranian patients, using PCR and Sanger sequencing at phase one. Then, as phase two, Next Generation Sequencing (NGS) in the form of targeted resequencing was utilized for analysis of exons from other related genes...

BACKGROUND: We evaluated factors that affect malignant transformation of leukoplakia in a sample of the Iranian population. METHODS: The records of patients with a clinical diagnosis of leukoplakia during a 20-year period from 1989-2009 referred to two of the largest referral centers in southern Iran were studied. Patients that developed malignant transformation were compared with patients that did not have malignant changes. RESULTS: Of 522 patients, female patients, those over 50 yr old and with lesions located on the tongue had the highest rate of malignant changes...

ZrO2 -biochar (ZrO2 -BC) nanocomposite was prepared by a modified sonochemical/sol-gel method. The physicochemical properties of the prepared nanocomposite were evaluated using scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray fluorescence, Fourier transform infrared spectroscopy and Brunauer-Emmett-Teller model. The sonocatalytic performance of ZrO2 -BC was investigated in sonochemical degradation of Reactive Yellow 39 (RY39). The high observed sonocatalytic activity of the ZrO2 -BC sample could be interpreted by the mechanisms of sonoluminescence and hot spots...

BACKGROUND: Intradural teratomas are an exceedingly unusual phenomenon. They are tumors with the cellular constituent source of all the 3 germ cell layers. CASE DESCRIPTION: We here report a case of an 18-year-old man with special pathologic features. There was no history of spinal dysraphism, congenital spinal abnormalities, previous spinal surgery, or lumbar puncture. Lumbosacral spine magnetic resonance imaging revealed a well-delineated, intramedullary mass at the L2-3 level...

BACKGROUND: An association between metabolic syndrome (MeS) and osteoarthritis (OA) has been reported in recent years; however, conflicting findings have been reported regarding this matter. Inhere we evaluated the relationship between different components of MeS and OA in a Fasa osteoarthritis registry (FOAS). METHODS: The registry includes all OA cases who referred to Fasa hospital (Iran) since 2013. Overall, 131 patients with OA with a Kellgren & Lawrence (K&L) score >1 and 261 controls were compared...

Learning from reward feedback in a changing environment requires a high degree of adaptability, yet the precise estimation of reward information demands slow updates. In the framework of estimating reward probability, here we investigated how this tradeoff between adaptability and precision can be mitigated via metaplasticity, i.e. synaptic changes that do not always alter synaptic efficacy. Using the mean-field and Monte Carlo simulations we identified 'superior' metaplastic models that can substantially overcome the adaptability-precision tradeoff...

PURPOSE: To evaluate the effect of non-keratometric ocular astigmatisms on visual and refractive outcomes after photorefractive keratectomy (PRK) for correction of myopic astigmatisms. METHODS: Seventy one eyes of 36 subjects were enrolled in this study. Patients underwent PRK for treatment of myopia. Subjects were evaluated for refractive error, keratometry, and visual acuity before and six months after surgery. Pre- and post-op non-keratometric astigmatisms were calculated by vectorial analysis of the difference between the corneal plane refractive astigmatism and keratometric astigmatism...
