Glyceraldehyde-3-phosphate dehydrogenase as a moonlighting protein in bacteria

Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is considered a housekeeping protein that is present in virtually all organisms, where it performs metabolic functions essential for survival. GAPDH plays an essential role in the process of energy production, and is also involved in numerous biological processes. GAPDH belongs to a subset of proteins called moonlighting proteins, in which different functions are associated with a single polypeptide chain. The multifunctionality of GAPDH has been described in pathogenic and probiotic microorganisms, in mammals and in plants. In this review, we summarize the moonlighting role of GAPDH in bacteria.

Incorporação de CuSO4 residual em argamassa, como método de disposição final

Residual CuSO4 was incorporated into the mass utilized for cement preparation. To a cement mass with 1:0.5:5 of cement, lime and sand to 0.25, 0.50, 0.75 and 1.00% of residual CuSO4 were added. The sulfate was mixed separately with lime and water to induce metal precipitation. The hardened test bodies were submerged in Milli-Q water for three months. No Cu was detected in the water by Atomic Absorption Spectrometry. The best proportion for mechanical resistance and porosity is 0.50%. The cement is adequate for non-structural objects.

Avaliação do efeito da piscicultura em sistemas aquáticos em Assis e Cândido Mota, São Paulo, por indicador de qualidade da água e análise estatítica multivariada

In this work, the impact of fish farming activities on the Queixada, Macuco and Pari-Veado Rivers in the Paranapanema watershed was evaluated. Physical, chemical and microbiological parameters were quantified in these aquatic systems followed by application of multivariate statistical analysis (MSA) and water quality index (WQI) tools. Watersheds where fish farming activities are predominant presented WQI > 52 indicating good quality, whereas MSA demonstrated bad quality for these aquatic bodies. The results showed that the degradation in this watershed follows the fish farming activity. The MSA index is more restricted than the "National Foundation Sanitation" (NFS) index routinely used to infer water quality.

Determinação de resíduos de nitrofurazona, furazolidona e nicarbazina em tecidos de origem animal

Foi padronizado e validado um método analítico para determinação de resíduos de nitrofurazona, furazolidona e nicarbazina em tecido muscular empregando-se extração com acetonitrila, purificação com cartuchos de sílica e C18 e detecção e quantificação por CLAE/UV. Nos ensaios com amostras fortificadas entre 5 e 200mg/kg as recuperações médias obtidas variaram de 73,6 a 95,6% com valores de C.V. entre 4,8 e 26,4%. O limite de detecção e quantificação do método foi de 5mg/kg, para cada um dos três resíduos estudados.
