The present study aimed to identify differentially expressed inflammatory factors observed in Wilms tumors (WT), and to investigate the association of these factors with clinical stage, pathological type, lymph node metastasis and vascular involvement of WT. Surface-enhanced laser desorption/ionization-time of flight mass spectrometry was performed to screen differentially expressed proteins am...

We purified an extracellular hemoglobin with the molecular mass of ca. 440 kDa from the whole homogenates of Oligobrachia mashikoi (phylum Pogonophora) by a one-step gel-filtration. The preparation was pure to be crystallized. The P50 values of the hemoglobin and the fresh blood prepared from O. mashikoi were about 0.82 Torr and 0.9 Torr, respectively, which were much lower than the P50 value o...

actinomycetes are an uncommon agent of human infections and its pathogenic factors are not known. the present study reports a rare case isolation of an actinomycete from a woman pleural fluid; the strain was identified by 16s rrna gene sequence analysis. this strain was tested to produce an extracellular protease that hydrolysis gelatin, casein and hemoglobin on agar mediums. the purification o...

introduction: using labeled peptides enjoys high importance in nuclear medicine. somatostatin analogs labeled with different radionuclide are vastly investigated for diagnosis or treatment of somatostatin receptor positive tumors. labeling somatostatin analogs with 99mtc as alternative of 111in needs doing different quality control method for determination of labeling yield and complex stabilit...

Recently, a system combining subtractive and kinetic enrichment of DNA fragments present in one complex genome but not in its normal or deviant counterpart has been developed (1,2,3)The authors designate this strategy 'difference cloning' and describe their protocols in detail (1,3). During our long-term endeavor for identifying disease genes for esophageal cancer, a common malignancy in North ...

It has been proposed that Fe stress may be used in the study of limiting factors in photosynthesis as an expermental means of varying photochemical capacity in vivo (Plant Physiol 1980 65: 114-120). In this paper the effect of Fe stress on photosynthetic unit number, size, and composition was investigated by measuring P700, cytochrome (Cyt)f, chlorophyll (Chi) a, and Chi b in sugar beet leaves....

Background: Bombesin shows high affinity for Gastrin-releasing peptide (GRP) receptors which over expressed on the cell surfaces of several human tumors particularly in prostate and breast cancers. The aim of this study was labeling of designed analogue with99mTc via HYNIC and Tricine /EDDA and evaluation as potential targeted tumor scintigraphic agent. Materials and Methods: HYNIC-Bombesin wa...
