Co-processing of n-hexadecane with lignin derived isoeugenol as a model compound was investigated in this work using low-cost mono- and bimetallic iron nickel supported on H-Y-5.1 zeolite. Different Fe-Ni metal ratios the catalyst led to different reaction rates processes product distribution. The presence just 0.26 wt% mixture made hydroisomerization-hydrocracking latter two-fold less active. ...

The escalating cost of Pt metal has prompted researchers to incorporate other metals into Pt/catalysts reduce the amount Pt. In this work, several bimetallic Pt-Zr/HY-zeolite catalysts were prepared by incorporating small amounts inexpensive Zr Pt/HY-zeolite form an active and selective catalyst. Results showed that although half required platinum was used, catalytic activity Pt-Zr/HY catalyst ...

BACKGROUND Congenital toxoplasmosis is associated with variable complications including encephalitis, microcephaly, hydrocephaly, hepatitis, lymphadenopathy and even intrauterine death. Presence of Toxoplasma gondii in human placenta may induce congenital infection. The aim of this study was to determine the genotypes of Toxoplasma gondii infection in human spontaneous aborted fetuses in Shiraz...

Methods to disintegrate old paraffin-embedded tissue blocks for the application of DNA flow cytometry open up new possibilities for retrospective studies on the correlation between tumor cell nuclear DNA pattern and prognosis of the neoplastic disease. In the present work we used such a method to study the relationship between DNA ploidy, histopathological grade, and survival for 50 patients wi...

Background: Bovine Leukemia Virus (BLV) is known by infections in bovine cattle and produce, in 30% of infected animals, persistent lymphocytosis significantly impacts the beef industry. It has been proposed that this virus could be transmitted to humans and be present in cases of breast cancer. Aim: to determine the presence of 380 bp of gag gene segment of BLV in paraffin-embedded breast tiss...

The extraction and further processing of nucleic acids (NA) from formalin-fixed paraffin-embedded (FFPE) tissues for microbiological diagnostic polymerase chain reaction (PCR) approaches is challenging. Here, we assessed the effects of five different commercially available nucleic acid extraction kits on the results of real-time PCR. FFPE samples from organs of Burkholderia pseudomallei-infecte...
