Expression of the virus envelope glycoprotein was measured PR-171 supplier by IFA and western blotting assays. The relative expression of env gene was determined using quantitative PCR. Our results show that the mi-env 231 and mi-env 1384 could effectively suppress the replication of ALV-J with an efficiency of 68.7-75.2 %. These data suggest that the miRNAs targeting the env can inhibit replication of ALV-J efficiently. This finding provides evidence that miRNAs could be used as a potential tool against ALV infection.”
“Antitumor effect of endo-biopolymer (EBP) obtained from
submerged mycelial culture of Pleurotus eryngii was investigated by using Sarcoma-180 bearing mice. The administration of EBP, intraperitoneally (10 to 80 mg/kg BW) at all dose ranges, inhibited the growth of the solid tumor and simultaneously increased the activity HSP990 cell line of natural killer (NK) cells significantly. While, 40 mg/kg BW treated group reduced the tumor formation
(53.1%), and increased the NK cell activity of splenocytes (25.0%) to a great extent. The complement activity of the EBP was 43.1% (1,000 mu g/mL). Phosphatase activity of macrophage was found to be increased up to 35.3% (100 mu g/mL) when compared with control. The chemical composition of EBP was found to contain carbohydrate (77.5%) and protein (21.6%). The major component sugars of EBP were glucose and mannose, while glycine, glutamic acid, and aspartic acid mainly constituted the protein moiety. These results revealed that EBP obtained from submerged culture of P. eryngii stimulate not only immune system but also antitumor activity.”
“A PKC412 supplier sample of archaeological iron slag from Northern Zimbabwe was characterised by Raman microscopy (RM) and electron beam analysis (EBA). The phases identified in a slag found at an ironmaking site not only reflect the chemical composition
of the slag but can also provide crucial information regarding the reconstruction and interpretation of the metallurgical operations, such as the prevailing redox conditions in a furnace at the time of cooling. Free iron oxides, such as haematite, magnetite and wustite, are important indicators of these redox conditions. But while classical techniques of phase identification can be used to identify the different iron oxides, they cannot distinguish between dissimilar oxidation states due to their non-stoichiometric nature, and also the effect of substituting elements in iron oxides. RM proved invaluable in both respects. By combining the results provided by RM and EBA, it was possible to identify (1) the free iron oxides, haematite and magnetite in the original ore, and magnetite and wustite in the slag, (2) oxidised magnetite and wustite, characterized by a shift to higher wavenumbers of their intense characteristic Raman bands and (3) Al3+-substituted magnetite and a solid solution between magnetite and hercynite (FeAl2O4).
