Diversity and three-dimensional structures of the alpha Mcr of the methanogenic Archaea from the anoxic region of Tucuruí Lake, in Eastern Brazilian Amazonia

ABSTRACT: Methanogenic archaeans are organisms of considerable ecological and biotechnological interest that produce methane through a restricted metabolic pathway, which culminates in the reaction catalyzed by the Methyl-coenzyme M reductase (Mcr) enzyme, and results in the release of methane. Using a metagenomic approach, the gene of the a subunit of mcr (mcrα) was isolated from sediment sample from an anoxic zone, rich in decomposing organic material, obtained from the Tucuruí hydroelectric dam reservoir in eastern Brazilian Amazonia. The partial nucleotide sequences obtained were 83 to 95% similar to those available in databases, indicating a low diversity of archaeans in the reservoir. Two orders were identified -the Methanomicrobiales, and a unique Operational Taxonomic Unit (OTU) forming a clade with the Methanosarcinales according to low bootstrap values. Homology modeling was used to determine the three-dimensional (3D) structures, for this the partial nucleotide sequence of the mcrα were isolated and translated on their partial amino acid sequences. The 3D structures of the archaean mcrα observed in the present study varied little, and presented approximately 70% identity in comparison with the mcrα of Methanopyrus klanderi. The results demonstrated that the community of methanogenic archaeans of the anoxic C1 region of the Tucurui reservoir is relatively homogeneous.

Uso de compostos derivados ftalimidicos e/ou sulfonamídicos no tratamento de doenças em que há a necessidade de diminuição dos níveis do fator TNF-alpha e a necessidade de uma fonte exógena de óxido nítrico, compostos derivados sulfonamídicos. Método de obtenção de um composto derivado sulfonamídico

Preparation and use of phthalimide and/or sulphonamide derivatives with nitric oxide donor properties, having activities in increasing gamma-globin gene expression and anti-inflammatory and analgesic activities, effective in the treatment of hematologic diseases which require reducing the TNF-[alpha] levels and an exogenous source of nitric oxide, such as sickle-cell disease. The functionalized phthalimide derivatives are designed from the prototypes thalidomide and hydroxyurea.

Polymorphisms in Oxytocin and alpha(1a) Adrenergic Receptor Genes and Their Effects on Production Traits in Dairy Buffaloes

The use of molecular markers may auxiliary the buffalo breeding. The oxytocin (OXT) and the adrenergic receptor alpha(1A) (ADRA1A) may be involved in milk ejection in ruminants. The aim of this study was to verify the existence of polymorphisms in the OXT and ADRA1A genes and their associations with milk production traits. A total of 220 buffaloes were genotyped using PCR-RFLP for both genes. The SNP identified in the ADRA1A gene was associated with protein percentage in dairy buffaloes. This is the first report of such association in the literature, which has not been studied in other species.
