This is a retrospective study on 162 node-negative patients, with both biochemical and clinical factors being measured for determination of prognostic markers. Steroid receptors were measured on all tumors, while tumor size, histological grade, ploidy status, and cell cycle kinetics indicators could not be found or measured on 25 or less of the patient group. The primary focus of this study was...

A biochemical (colorimetric) assay of bacteriophage lambda induction was utilized in the detection, identification, and purification of DNA-interacting natural products with potential antitumor activity. A set of 142 standard antibiotics, composed principally of natural products with established antitumor activity and/or defined mechanisms of action, was tested in the assay. As expected, most i...

A biochemical (colorimetrie) assay of bacteriophage A induction was utilized in the detection, identification, and purification of DMA-interacting natural products with potential antitumor activ ity. A set of 142 standard antibiotics, composed principally of natural products with established antitumor activity and/or de fined mechanisms of action, was tested in the assay. As ex pected, most ind...

In this study 130 bulk tank milk samples which were delivered to the Pegah Pasturisation Factory inMashhad were collected randomly during the summer months. Samples were firstly enriched in modifiedtrypticase soy broth containing novobiocin, followed by plating onto sorbitol MacConkey agar supplementedwith cefixime and potassium tellurite for isolation of Escherichia coli O157:H7. Consequently ...

Background: The purpose of this study was to ascertain the effects hot, dry spring and summer weather on endocrinological biochemical properties buffaloes with help physiological as well analysis. Methods: Like plasma glucose using GOD-POD kits, total protein Autospan Blood Urea Nitrogen MBK kits DAM assay, cortisol hormone by bovine enzyme linked immunosorbent assay kit etc. Result: During sea...

Sensitive and reliable monitoring of kinase activity was reported by using highly efficient fluorescence resonance energy transfer of conjugated polymer nanoparticles (CPNs) to a rhodamine labelled peptide substrate.

Genetic recombination in single-strand, positive-sense RNA viruses is a poorly understand mechanism responsible for generating extensive genetic change and novel phenotypes. By moving a critical cis-acting replication element (CRE) from the polyprotein coding region to the 3' non-coding region we have further developed a cell-based assay (the 3'CRE-REP assay) to yield recombinants throughout th...
