Streptococcus agalactiae, also known as group B Streptococcus, is an aetiological agent of urinary tract infection (UTI) in adults, including cystitis, pyelonephritis and asymptomatic bacteriuria (ABU). Whereas ABU-causing S. agalactiae (ABSA) have been shown to grow achieve higher culture denstity human urine compared uropathogenic (UPSA) other phenotypic distinctions between isolated from dif...

The amyloid precursor protein (APP) undergoes a variety of modifications through enzymatic cleavage leading to the formation of pro-Alzheimer’s disease (AD) and anti-AD biologically active peptides. One such cleavage product, APP ΔC31 results from the caspase cleavage of the full length APP protein (APP695) at amino acid Asp664 as well as the concomitant formation of the 31 amino acid C-termina...

objectives: this study aimed to compare the in vitro cytotoxic activity of propolis, a bioactive material made by the honeybee, and calcium hydroxide (ch) and their effect on formation of mineralized nodules by human dental pulp stem cells (hdpscs). methods: in this in vitro study, hdpscs were obtained from the cellular and molecular oral biology laboratory of school of dentistry, shahid behesh...

A glycopolymer carrying trehalose was found to suppress the formation of amyloid fibrils from the amyloid β peptide (1-42) (Aβ), as evaluated by thioflavin T assay and atomic force microscopy. Glycopolymers carrying sugar alcohols also changed the aggregation properties of Aβ, and the inhibitory effect depended on the type of sugar and alkyl side chain. Neutralization activity was confirmed by ...

Wilms tumor (WT) is the most common pediatric malignant primary renal tumor. Carboplatin (CRB), a platinum compound is widely used in the treatment of multiple cancers including ovarian, lung, head and neck, and wilm’s tumor. However lower uptake of CRB in cancer cells and toxicity concerns in healthy cells often limited its clinical outcome. The aim of this study was to investigate the antitum...

Objective(s):The inhibitory effects of iron chelators, and FeCl3 chelation on biofilm formation and swarming motility were investigated against an opportunistic human pathogen Pseudomonas aeruginosa. Materials and Methods:The inhibitory activity of 2,2’-bipyridyl, lipoic acid, kojic acid and picolinic acidonbiofilm formation of P. aeruginosa strain PAO1 and three clinical isolates (P. aeruginos...

Netrin-1 is a neural guidance cue that also regulates vascular development. Controversial results, however, have been obtained concerning the roles of netrin-1 in vascular development both in vivo and in vitro. In the present study, two in vitro angiogenesis assays were compared to evaluate the effects of netrin-1 secreted by retrovirally transduced melanoma cells (Mel2a-netrin1) on tube format...

conclusions the results of this study illustrated the high prevalence of antibiotic resistant biofilm-producing s. epidermidis strains in this hospital, which could be a reservoir for antibiotic resistance genes. results the results of the biofilm assay revealed that 82% of strains produced black colonies on congo red agar plates and 68% were able to attach strongly to polystyrene microplates. ...
