bovine leukemia virus (blv) is a retrovirus causing a chronic leukemia/lymphoma in cattle in many countries around the world. screening for antibodies by elisa has been the primary means of detecting the presence of this virus. it is not yet known if this assay will detect antibodies in all cattle during a concomitant bovine leukemia virus infection. the polymerase chain reaction (pcr) of the t...
background and objective: formalin-fixed paraffin-embedded tissues are a valuable source of dna for molecular studies. we designed and optimized an efficient procedure for dna extraction from formalin-fixed paraffin embedded tissues. materials and methods: seventy three blocks of cervical paraffin-embedded tissues were investigated. dna was extracted using 45 minutes boiling in alkaline solutio...
introduction: nocardia is saprophytic soil bacterium of the actinomycetes families. nocardia has high diversity of species and due to species diversity of nocardia, phenotypic tests are essential for early identification of nocardia species. methods: 155 soil samples from different regions of north khorasan province in iran were collected, including: urban and rural areas. isolation of nocardia...
-Selected monoclonal antibodies (McAbs) isolated after immunization of rats with a human colonic carcinoma membrane preparation, have been screened on frozen and paraffin sections of colonic tissue, using immunohistochemical techniques, in order to provide additional information with regard to specificity and crossreactivity with normal tissues. Of 10 McAbs previously shown to bind to a colonic...
The cytoskeleton regulatory protein Mena is reportedly overexpressed in breast cancer; however, data regarding its expression level and clinical significance in gastric carcinoma (GC) is limited. The aim of the present study was to investigate Mena expression levels and prognostic significance in GC. Mena mRNA expression level was determined by reverse transcription-quantitative polymerase chai...
The induction of paraffin oxidation in intact cells of Pseudomonas aeruginosa was investigated. Oxidation of (14)C-heptane by cell-free extracts of adapted cells showed that the activity of whole cells is a reliable reflection of the synthesis of the first enzyme in the degradation of n-alkanes. Induction was significantly affected by glucose and could be completely repressed by malate. The ami...
Abstract Background Domestic cats rarely develop hepatocellular carcinoma. The reason for the low prevalence is unknown. Reductions in ploidy have been associated with hepatic carcinogenesis. Recent work mice has shown that livers more polyploid hepatocytes are protected against development of Hepatocyte domestic cat not evaluated. We hypothesized would be reduced peri-tumoral and neoplastic co...
The influence of heat transfer characteristics fluids filled with paraffin core-metallic shell nanoencapsulated phase change material (PCM) on photothermal conversion and storage in a volumetrically heated solar system is numerically analysed. results show that paraffin/Al, paraffin/Au, paraffin/Ag, paraffin/Cu enhance the energy by 68, 73, 92 86 %, respectively as compared water-based Al, Au, ...
Histopathological diagnosis in most of the world's hospitals is based upon formalin-fixed and paraffin-embedded (FFPE) tissues. Although this standard fixation and embedding procedure keeps the tissue in excellent form for morphological and immunohistological analysis, FFPE is inappropriate for nucleic acids and protein studies. We investigated the potential value of RCL2, a new non-toxic fixat...
Comprehensive genetic analysis of colorectal malignant tumors by microarrays has identified translocase of the outer mitochondrial membrane 34 (TOMM34) and ring finger protein 43 (RNF43) as highly expressed oncogenes in malignant colorectal tumors. Vaccine therapy using cancer peptides synthesized using the amino acid sequences of tumor antigens is currently undergoing clinical trials. Since it...
