Adherent-invasive Escherichia coli (AIEC) strains are genetically variable and virulence factors for AIEC are non-specific. FimH is the most studied pathogenicity-related protein, and there have been few studies on other proteins, such as Serine Protease Autotransporters of Enterobacteriacea (SPATEs). The goal of this study is to characterize E. coli strains isolated from patients with Crohn's ...

background: inhibin is a dimeric glycoprotein that has a depressive effect on the anterior hypophyse secretion. the level of this tumor marker is undetectable in menopause women. in patients with gynecological cancer, especially granulosa and epidermal-type (mucinous), ovarian cancers considerable increase in the serum level of inhibin has been reported. the increased level of inhibin has been ...

Pathogen detection tools with high reliability are needed for various applications, including food and water safety and clinical diagnostics. In this study, we designed and validated an in situ-synthesized biochip for detection of 12 microbial pathogens, including a suite of pathogens relevant to water safety. To enhance the reliability of presence/absence calls, probes were designed for multip...

The in vivo virulence patterns of promastigote populations defined on the basis of agglutination by the lectin peanut agglutinin (PNA) were studied for various cloned lines of Leishmania major. Promastigotes derived from logarithmic-phase cultures, which were routinely 100% agglutinated at 100 micrograms of PNA per ml, were relatively avirulent for BALB/c mice. The relative virulence of station...

beauveria bassiana (balsamo) vuillemin is an important natural regulator of insect populations. identification of a suitable molecular marker for detecting a virulent phenotype on a target pest would be useful in screening for effective isolates against the pest. nine isolates of b. bassiana were tested for their virulence to adults of tribolium castaneum (herbst) in laboratory bioassay with 1×...

a greenhouse experiment was conducted in 2013 in research lab of karaj islamic azad university to determine the yield and activity of chemical markers as the response to different concentrations of cadmium (cd) (0, 5, 10 and 20 mg of cd/kg of soil) in wheat cultivars (karaj 1 and karaj 2). treatments were tested in a factorial experiment with four replications in 7.5 kg plastic pots. the respon...

Background: Avian pathogenic Escherichia coli (APEC), which is the causative agent of colibacillosis, harbors several putative virulence genes. An important trait of APEC for both poultry and public health is antibiotic resistance. Objectives: In the present study, some potential virulence genes of APECs isolated from Northeast of Iran and their resistance to the quinolones antibiotics were stu...

objective: to evaluate whether systemic inflammatory markers (neutrophil to lymphocyte ratio (nlr), platelet to lymphocyte ratio (plr) and red blood cell distribution width (rdw) to platelet ratio (rpr)) can be used as reliable markers for the diagnosis of premature ovarian insufficiency (poi) and to determine if there is a relationship between these markers and follicle stimulating hormone (fs...

background: the availability of testis specific genes will be of help in choosing the most promising biomarkers for the detection of testicular sperm retrieval in patients with non-obstructive azoospermia (noa). testis specific chromodomain protein y 1 (cdy1) is a histone acetyltransferase which concentrates in the round spermatid nucleus, where histone hyperacetylation occurs and causes the re...
