background and purpose: over the past years, the role of fungi as a cause of nosocomial infections in hospitalized patients has been accentuated. candida species constitute an important group of fungi causing diseases in immunocompromised patients. oropharyngeal candidiasis continues to be a prevalent infection in immunodeficient patients. in this study, we aimed to determine the incidence of o...

background and purpose: oropharyngeal candidiasis (opc) and antifungal drug resistance are major health concerns in patients with human immunodeficiency virus (hiv). the increased reports of antifungal resistance and expanding drug therapy options prompted the determination of antifungal susceptibility profile. the present study was performed to determine the antifungal susceptibility of candid...

background and objectives: bordetella species colonize the respiratory tract of mammals and thereby cause the whooping cough. most of the species produce adenylate cyclase - a toxin ( hemolysin ) responsible for increasing intracellular cyclic amp (camp) levels in mammalian neutrophils and macrophages and as a consequence their phagocytic function get impaired . this study was carried out to is...

neuroserpin, a member of the serine proteinase inhibitor (serpin) superfamily, is known to be a neuroprotective factor in the focal ischemic stroke followed by reducing the microglial activation. neuroserpin is a protein rich of methionine residues that can scavenge the free radical species which may increase its neuroprotective effect. on the other hand, the oxidative modifications of the amin...

background: combination of glycation and oxidation is associated with diabetes mellitus. the aim of this study was to clarify the effect of glycated proteins in presence of transition metal ions on production of reactive oxygen species (ros) in rat hepatocyte suspension.  methods: glycated albumin was prepared by incubation of bovine serum albumin with 100 mm glucose in 0.3 m phosphate buffer a...

background and purpose: in people wearing dentures, the growth of various candida species under the prosthesis leads to the formation of biofilm, which can play the role of a reservoir for candida and other kinds of microbes. since nano-chitosan particles can cause lasting antimicrobial activity, a more recent approach that utilizes acrylic resins with nano-chitosan particles is proposed. there...

objective(s) neutrophil gelatinase-associated lipocalin (ngal/lcn2), comprise a group of small extracellular proteins with a common p-sheet-dominated 3-dimensional structure. in the past, it was assumed that the predominant role of lipocalin was acting as transport proteins. recently it has been found that oxidative stress induces lcn2 expression. it has been also proved that electromagnetic fi...

b a ckground : anopheles culicifacies is an important vector of malaria in southeast asia, contributing to almost 70%of malaria cases in india. it exists as a complex of five morphologically indistinguishable species a, b, c, d and e with varied geographical distribution patterns. in india, 8% of the total population of madhya pradesh (central india) contributes about 30% of total malaria cases...

this study evaluates changes in species composition, catch, and cpue of three species of kilkas in the caspian sea from 1961 to 2009. the effects of fluctuations in sea level rise and fall on the catch of kilka as well as the impacts of a recent invasion by mnemiopsis leidyi (ctenophora) were assessed in terms of species composition and cpue of kilkas in the iranian coastal region of the caspia...

a specific polymerase chain reaction (pcr) method was applied for identification of bovine (bos taurus), ovine (ovis aries) and caprine (capra hircus) pure and binary mixtures of raw and heat-processed meats. these meats are used in food industry products and/or for direct consumption of consumers. the mitochondrial dna was amplified as a template in a pcr reaction by use of specific primers re...
