N-Heterocyclic carbene and phosphorus ylides are inorganic and organometallic ligands, and their coordination chemistry with transition elements, particularly group 11 metals, would be noticeable. This study seeks to characterize the structure and nature of the C→M bond of group 11 metals (M = Cu(i), Ag(i), Au(i)) in coordination with different monodentate phosphorus ylides {P(Ph)3CHR} and N-heterocyclic carbenes (NHC(R)) (where R = F, Cl, Br, CF3, CH3, H, C(CH3)3, Si(CH3)3, SiH3, Ph). In this regard, DFT calculations with the PBE/def2-TZVP level of theory were applied...

BACKGROUND: A number of complex and rare mutations in epidermal growth factor receptor (EGFR) gene have been identified and the clinical implication of serum EGFR ligands has also been reported. However, the prognostic significance of these mutations and also the serum EGFR and its ligands in Non-Small Cell Lung Carcinoma (NSCLC) has remained a challenging issue. This study is aimed at finding the prognostic importance of EGFR rare mutations and serum EGFR, amphiregulin (AR), and TGF-α (Transforming Growth Factor-alpha) in NSCLC...

BACKGROUND: Genetic polymorphisms of drug metabolisms by cytochrome P450 (P450s) could affect drug response, attracting particular interest in the pharmacogenetics. Due to the importance of CYP2C19* 17 allele and its capability of super- fast metabolism and also lack of information about distribution of the alleles in Iranian population, this research aimed to use High Resolution Melting (HRM) method compared to PCR-RFLP for genotyping healthy Iranian population. METHODS: Blood samples were collected from 100 healthy Iranian volunteers...

Melissa officinalis L. is a medicinal plant with a large variety of pharmacological effects and traditional applications. This study aimed to evaluate the protective and antioxidant activities of the extract of M. officinalis aerial parts on human umbilical vein endothelial cells (HUVECs) under oxidative stress induced by H2O2. Cells were incubated with H2O2 (0.5 mM, 2 h) after pretreatment with M. officinalis extract (25-500 μg/mL). Cell viability was evaluated by 3-(4, 5- Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay...

A 31-year old woman with persistent fever for 6 weeks and unresponsive to antibiotic therapy came for rheumatologic investigation. After computed tomography (CT) studies of her neck, thorax and abdomen revealed bilateral cervical, axillary and retroperitoneal lymph node enlargements, histopathologic evaluation of the resected nodes showed features of histiocytic necrotizing lymphadenopathy suggestive of Kikuchi-Fujimoto's lymphadenopathy. Kikuchi-Fujimoto Disease (KFD) involving the retroperitoneal nodes is extremely unusual and even more challenging to diagnose when there are no early signs of extranodal involvement or abdominopelvic pain...

Allergic asthma is an airway disease, characterized by reversible bronchoconstriction, chronic inflammation of the airway, and thickness of smooth muscle in the respiratory tract. Asthma is orchestrated by an excessive Th2-adaptive immune response, in which innate immunity plays a key role. Recently TLRs have received more and more attention as they are central to orchestrate the innate immune responses. TLRs are localized as integral membrane or intracellular glycoproteins with those on the cell surface sensing microbial antigens and the ones, localized in intracellular vesicles, sensing microbial nucleic acid species...

The photophysical properties of nine 1,5-benzodiazepine-2,4-dione (BZD) derivatives were investigated using absorption and fluorescence spectral techniques in dimethyl sulfoxide. The trend of red shifts caused by the substitutions had full compliance with the trend of decreasing the calculated band gap (ΔELUMO-HOMO) by semi-empirical AM1 and DFT/B3LYP/6-311+G* computational methods. The positive solvatochromism of BZD a demonstrated the π-π* nature of the singlet excited state. Dual fluorescence was observed in the emission spectra of BZD f and g, while their spectrum in different concentration showed only one peak short wavelength (SW) in dilute solutions...

Background: In many countries gastric cancer has the highest incidence among the gastrointestinal cancers and is the second most common cancer in Iran. The aim of this study was to identify and map high risk gastric cancer regions at the county-level in Iran. Methods: In this study we analyzed gastric cancer data for Iran in the years 2003-2010. Areato- area Poisson kriging and Besag, York and Mollie (BYM) spatial models were applied to smoothing the standardized incidence ratios of gastric cancer for the 373 counties surveyed in this study...

An accurate estimation of the prevalence of paediatric asthma in Alberta and elsewhere is hampered by uncertainty regarding disease definition and diagnosis. Electronic medical records (EMRs) provide a rich source of clinical data from primary-care practices that can be used in better understanding the occurrence of the disease. The Canadian Primary Care Sentinel Surveillance Network (CPCSSN) database includes cleaned data extracted from the EMRs of primary-care practitioners. The purpose of the study was to develop and validate a case definition of asthma in children 1-17 who consult family physicians, in order to provide primary-care estimates of childhood asthma in Alberta as accurately as possible...

An experiment was conducted to investigate the effects of dietary nanoselenium supplementation at 0, 0.6 and 1.2 mg/kg of diet on growth performance, serum biochemical parameters, immune response, antioxidant capacity, and jejunal morphology of 29-d-old male broilers subjected to heat stress at 37 ± 1°C for 14 d. Broilers were fed for 42 d on the experimental diets. The results showed that nanoselenium supplementation had no effect on growth performance, but it supplementation at the rate of 1.2 mg/kg diet decreased the serum concentration of cholesterol prior to the heat exposure...

This survey was done to investigate the efficacy of the in-house indirect ELISA (iELISA) and Dot-ELISA methods Prepared from excretion-secretory (ES Ag) and Crude (Cr Ag) antigens of Fasciola for sero-diagnosis of Fasciola gigantica in cattle. The liver specimens of slaughtered cattle were collected and their liver examined macroscopically and microscopically for infestation to fasciolosis. Sera from two groups of cattle, one infected with fasciolosis (n = 60) and the other non-infected with fasciolosis (n = 60), were used in the iELISA and Dot-ELISA test; grouping based on histopathology results...

Screening among some new isolated bacteria from oily samples, which were capable of producing extracellular polymeric substances (EPSs), one was selected and identified as Bacillus sonorensis. An efficient micro-total analysis approach was carried out to assay the produced EPSs by this bacterium. Sucrose and yeast concentrations as carbon and nitrogen sources, respectively, sodium salt concentration and initial pH were selected to be the variables in experimental design. Production of EPS in optimal condition was increased by 5...

Self-peeling of gecko toes is mimicked by integration of film-terminated fibrillar adhesives to hybrid nematic liquid crystal network (LCN) cantilevers. A soft gripper is developed based on the gecko-inspired attachment/detachment mechanism. Performance of the fabricated gripper for transportation of thin delicate objects is evaluated by the optimum mechanical strength of the LCN and the maximum size of the adhesive patch.

Recent years have seen the rise of invasive fungal infections, which are mostly due to the increase in patients. Three major opportunistic fungal species in human are Aspergillus fumigatus, Candida albicans, and Cryptococcus neoformans that pose the biggest concern for these immunocompromised patients' mortality. The growing occurrence of opportunistic fungal infections has sparked the interest to understand defense mechanisms against pathogenic fungi. Toll-like receptors (TLRs), as a part of innate immune system, play an important role for recognizing the invading microorganisms and initiating sufficient immune responses...
