N(2)-Monomethylguanosine-10 (m(2)G10) and N(2),N(2)-dimethylguanosine-26 (m(2)(2)G26) are the only two guanosine modifications that have been detected in tRNA from nearly all archaea and eukaryotes but not in bacteria. In Saccharomyces cerevisiae, formation of m(2)(2)G26 is catalyzed by Trm1p, and we report here the identification of the enzymatic activity that catalyzes the formation of m(2)G1...

The Basel 1988 Capital Accord is arguably the most successful of all recent financial ‘standards’. Although it was designed for internationally active banks in G10 countries, more than 100 countries c laim to adhere to it and many apply the Accord to all banks. Significant changes to this Accord are currently under discussion and a final version is to be published in 2002 for implementation by ...

PURPOSE Determine the effects of the MSG (monosodium glutamate) in the offspring of pregnant rats through the comparison of the weight, NAL (nasal-anal length) and IL (Index of Lee) at birth and with 21 days of life. METHODS Pregnant Wistar rats and their offspring were divided into 3 groups: GC, G10 and G20. Each of the groups received 0%, 10% and 20% of MSG, respectively from coupling until...

Group A rotavirus-positive stool specimens, collected from 432 hospitalized patients of all age groups with diarrhoea during 1990-1997 from Pune, India, were characterized for subgroups (SGs) and G serotypes (1, 2, 3, 4, 6, 8, and 10). ELISA for subgrouping was carried out by employing subgroup I and II-specific monoclonal antibodies (MAbs). For serotyping, MAbs against G1 (Ku), G2 (S2), G3 (Yo...

Advanced melanoma is the most aggressive form of skin cancer. It is highly metastatic and dysfunctional in melanogenesis; two processes that are induced by H2O2. This work presents a melanoma cell model with low levels of H2O2 induced by catalase overexpression to study differentiation/dedifferentiation processes. Three clones (A7, C10 and G10) of human A375 amelanotic melanoma cells with quite...

This is the first report of meiotic division in Uro-chloa adspersa (Trin.) collected from the Brazilian Chaco. Meiotic analyses were performed on three specimens of U. adspersa named G10, G15, and G16. Inflorescences were collected and fixed in a mixture of ethanol and acetic acid (3:1, v/v) for 24 h and then stored in 70% alcohol. Diakinesis revealed different chromosome numbers and ploidy lev...

Background and Aims: Rotaviruses are the main cause of gastroenteritis in the young of human and a variety of animals in the world. Rotavirus G6 and G10 are the most prevalent genotypes in cattle worldwide, but are also found in human with possible origination from animals. Materials and Methods: In this work, we have detected the G6 and G10 genotypes of bovine rotaviruses isolated from di...
