background: a powerful and improved technique, proton induced x-ray emission (pixe) has been performed-yielding the elemental composition of 17 samples of surgically excised malignant and normal tumors of breast tissue. the samples without any further process as thick targets were put on capton foil backing. there are no homogenizing processes. the pixe spectra analysis was performed using he n...

background: nowadays use of specific antivenin for latrodectism is considered as the most effective treatment in the world. this study was undertaken to investigate the efficacy of specific antivenom against histopathological complications caused by latrodectus dahli venom on liver, heart and kidneys tissues within 72 h. methods: two groups were selected, each one contained 6 male new zealand r...

background: baculoviral inhibitor of apoptosis repeat-containing 5 (birc5) gene is an inhibitor of apoptosis that expresses in human embryonic tissues but it is absent in most healthy adult tissues. the copy number of birc5 has been indicated to be highly increased in tumor tissues; however, its association with the age of onset in breast cancer is not well understood. methods: forty tumor tiss...

An 11-year-old boy was found to have primary hyperoxaluria type I (urine oxalate 828mg/l, N 140–420mg/l). His mother had kidney stones and the parents were second degree relatives. After 18 months of dialysis, femoral neck fracture occurred, which was assumed to be related to renal osteodystrophy. During the surgical procedure to fix the fracture site internally, biopsies were taken which showe...

Correct interactions between transcription factors (TFs) and their binding sites (TFBSs) are of central importance to gene regulation. Recently developed chromatin-immunoprecipitation DNA chip (ChIPchip) techniques and the phylogenetic footprinting method provide ways to identify TFBSs with high precision. In this study, we constructed a userfriendly interactive platform for dynamic binding sit...

The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...
