background and objectives:gamma-irradiation is used vastly for both decontamination and sterilization of natural products; but these high-energy rays can affect heat-sensitive essential oils. methods: the oleo-gum-resin of boswellia carterii (burseraceae) was sterilized by γ-irradiation at dose 30 kgy. the essential oils obtained by hydrodistillation of non-irradiated boswellia (nib) and irradi...

Abstract Background Methyl‐aminolevulinate‐based photodynamic therapy (MAL‐PDT) has been successfully used in early‐stage mycosis fungoides (MF) lesions. However, the long‐term outcome of initially responding lesions not systematically investigated to date. To address this issue, we hereby report a large series MF treated with MAL‐PDT and followed up for 1 year after initial treatment. Objectiv...

Results The isolate was confirmed as E. coli O25b-sequence type (ST) 131 clone of B2 phylogenetic group. The isolate was resistant to all antibiotics tested except sulfamethoxazole, trimethoprim and nitrofurantoin and Etest confirmed that it is highly resistant to meropenem, imipenem, ciprofloxacin, cefotaxime and ceftazidime with MIC values of >16 mg/l, 32 mg/l, >64 mg/l, 32 mg/l & >32mg/l res...

Clostridium perfringens iota-toxin is a binary toxin composed of an enzyme component (Ia) and a binding component (Ib). Each component alone lacks toxic activity, but together they produce cytotoxic effects. We examined the cytotoxicity of iota-toxin Ib in eight cell lines. A431 and A549 cells were susceptible to Ib, but MDCK, Vero, CHO, Caco-2, HT-29, and DLD-1 cells were not. Ib bound and for...

Background: Asthma is recognized as a common cause of disability, of great economic cost, and of preventable deaths. In this study we aimed to test our hypothesis to evaluate the relationship between the Human Platelet Antigen-1(HPA-1) polymorphism and bronchial asthma and its severity, which would suggest genetic variances that may be responsible for expression or activation of these receptors...

Inattentional Blindness (IB) occurs when an observer who is engaged in a resource consuming task fails to notice an unexpected although salient stimulus appearing in his/her visual field. The incidence of IB can be affected by changes in stimulus-driven properties of the display, but very little research has examined individual differences in propensity for IB. The current research examines ind...

The Col Ib-P9 plasmid content of colicinogenic cells has been measured by both sedimentation analysis of cleared lysates and by deoxyribonucleic acid hybridization to purified Col Ib-P9 factor deoxyribonucleic acid. The results show an independence between mitomycin C-induced colicin synthesis and Col Ib-P9 replication. In addition, the ratio of the various molecular configurations (i.e., coval...

One of the major issues banks are faced with in providing Internet Banking (IB) services is the adoption of these services by the customers. This study seeks answer to the question that whether bank customers’ awareness of the services and advantages of IB is effective in reducing the negative effect of customers’ perceived risk on their intention of IB adoption. To this end, the two constructs...
