Urinary Estrogen Metabolites and Self-Reported Infertility in Women Infected wi...
Santos, J.; Gouveia, M.J.; Vale, N.; Delgado, M. de L.; Gonçalves, A.; da Silva, J.M.; Oliveira, C.; Xavier, P.; Gomes, P.; Santos, L.L.; Lopes, C.Schistosomiasis is a neglected tropical disease, endemic in 76 countries, that afflicts more than 240 million people. The impact of schistosomiasis on infertility may be underestimated according to recent literature. Extracts of Schistosoma haematobium include estrogen-like metabolites termed catechol-estrogens that down regulate estrogen receptors alpha and beta in estrogen responsive cells. In addition, schis...
Perceived stress in obsessive-compulsive disorder is related with obsessive but...
Morgado, Pedro; Freitas, D.; Bessa, J. M.; Sousa, Nuno; Cerqueira, JoãoObsessive–compulsive disorder (OCD) is achronic psychiatric disorder characterized by recurrent intrusive thoughts and/or repetitive compulsory behaviors. This psychiatric disorder is known to be stress responsive, as symptoms increase during periods of stress but also because stressful events may precede the onset of OCD. However, only a few and inconsistent reports have been published about the stress percept...
Cell genesis and dendritic plasticity : a neuroplastic pas de deux in the onset...
Pinheiro, António Mateus; Patrício, P.; Bessa, J. M.; Sousa, Nuno; Pinto, LuísaBrain neuroplasticity is increasingly considered to be an important component of both the pathology and treatment of depressive spectrum disorders. Recent studies shed light on the relevance of hippocampal cell genesis and cortico-limbic dendritic plasticity for the development and remission from depressive-like behavior. However, the neurobiological significance of neuroplastic phenomena in this context is sti...
Addition of electron acceptors stimulates methanogenesis from lipids by anaerob...
Guedes, Ana P.; Cavaleiro, A. J.; Silva, Sérgio; Alves, M. M.; Stams, A. J. M.; Sousa, D. Z.Incubation of anaerobic sludge with triolein or oleate in the presence of nitrate or sulphate led to an increased methane production, relatively to incubations without inorganic electron acceptor. Faster methane production was obtained in assays amended with nitrate. Methanogenesis occurred after the reduction of alternative electron acceptors.
Role of syntrophic microbial communities in high-rate methanogenic bioreactors
Stams, A. J. M.; Sousa, D. Z.; Kleerebezem, Robbert; Plugge, Caroline M.Anaerobic purification is a cost-effective way to treat high strength industrial wastewater. Through anaerobic treatment of wastewaters energy is conserved as methane, and less sludge is produced. For high-rate methanogenesis compact syntrophic communities of fatty acid-degrading bacteria and methanogenic archaea are essential. Here, we describe the microbiology of syntrophic communities in methanogenic reactor...
Influence of L-cysteine, oxygen and relative humidity upon survival throughout ...
Rodrigues, D.; Sousa, S.; Rocha-Santos, T.; Silva, J.P.; Lobo, J.M. Sousa; Costa, P.; Amaral, M. H.; Pintado, M. M.; Gomes, A. M.; Malcata, F. X.The survival rates of Lactobacilus acidophilus Ki, Lactobacillus paracasei L26 and Bifidobacterium animalis BB-12 were studied after whey protein microencapsulation via spray-drying, with or without L-cysteine- HCl, and storage up to 6 months at 5 C and 22 C, with variation in relative air humidity and oxygen levels. Lb. paracasei L26 was the least susceptible to storage conditions: above 106 cfu g 1 were rec...
Solubility of carbon dioxide in aqueous solutions of amino acid salts
A. F. Portugal; J. M. Sousa; F. D. Magalhães; A. MendesThe solubility of CO2 in aqueous solutions of potassium glycinate was measured in a stirred reactor, at temperatures from 293 to 351 K, for amino acid salt concentrations ranging between 0.1 and 3.0 mol dm(-3) and CO2 partial pressures up to 6 x 10(4) Pa. CO2 Solubility in potassium threonate 1.0 mol dm(-3) was also measured at 313 K. It was observed that amino acid salt solutions can be very interesting for CO...
Efeito de tipo de óleo adicionado à dieta, sobre o teor de colesterol em partes...
FERREIRA,J.M.; SOUSA,R.V.; BRAGA,M.S.; VIEIRA,E.C.; CAMPOS,E.J.Foi conduzido um experimento com o objetivo de avaliar níveis de energia metabolizável normalmente utilizado nas rações de frangos de corte, obtidos pela inclusão de óleos vegetais (soja, canola e palma) e seus efeitos sobre o teor de colesterol da pele e músculos da coxa e peito, levando-se em consideração a linhagem e sexo. Foram utilizados 2.400 pintos de 1 dia, das linhagens comerciais Hubbard e Avian Farms...
