Human mesenchymal stem cells response to multi-doped silicon-strontium calcium ...
Rodríguez-Valencia, Cosme; Pereiro, Iago; Pirraco, Rogério; Lopéz-Álvarez, M.; Serra, J.; González, P.; Marques, A. P.; Reis, R. L.The search for apatitic calcium phosphate coatings to improve implants osteointegration is, nowadays, preferentially focused in the obtaining of compositions closer to that of the inorganic phase of bone. Silicon and strontium are both present in trace concentrations in natural bone and have been demonstrated, by separate, to significantly improve osteoblastic response on calcium phosphate bioceramics. This wor...
Silicon-hydroxyapatite bioactive coatings (Si-HA) from diatomaceous earth and s...
Lopez-Alvarez, M.; Solla, E. L.; Gonzalez, P.; Serra, J.; Leon, Bétty; Marques, A. P.; Reis, R. L.The aim of this study consisted on investigating the influence of silicon substituted hydroxyapatite (Si–HA) coatings over the human osteoblast-like cell line (SaOS-2) behaviour. Diatomaceous earth and silica, together with commercial hydroxyapatite were respectively the silicon and HA sources used to produce the Si–HA coatings. HA coatings with 0 wt% of silicon were used as control of the experiment. Pulsed la...
A longitudinal study of porcine proliferative enteropathy in a commercial pig f...
Rodríguez,J.C.; Alvarez,M.; Rodríguez,L.; Segura,J.C.Avaliou-se a distribuição de Lawsonia intracellularis em fezes de suínos, coletadas diretamente no reto, durante a fase de crescimento/terminação, sob condições de campo, e determinou-se o efeito da infecção L. intracellularis no ganho de peso. O estudo epidemiológico longitudinal foi desenvolvido em uma granja de múltiplos sítios em Yucatan, México. A granja possuía três sítios geograficamente isolados com o s...
Elastic, inelastic scatterings and transfer reactions for 16,18O on 58Ni descri...
Alves,J. J. S.; Gomes,P. R. S.; Lubian,J.; Chamon,L. C.; Anjos,R. M.; Pereira,D.; Rossi Jr.,E. S.; Silva,C. P.; Alvarez,M. A. G.; Nobre,G. P. A.We have used a parameter - free potential, obtained from data analysis at sub-barrier energies, to explain our measurements of elastic and several inelastic scattering cross sections for the 16,18O + 58Ni systems at an energy above the barrier. The data were analyzed through extensive coupled-channel calculations. Transfer cross sections could also be explained by the same interaction, which is consistent with ...
Assessment of soil properties by organic matter and EM-microorganism incorporation
Valarini,P. J.; Díaz Alvarez,M. C.; Gascó,J. M.; Guerrero,F.; Tokeshi,H.Properties of a claim loam soil, collected in Aranjuez (Madrid) and enriched with organic matter and microorganisms, were evaluated under controlled temperature and moisture conditions, over a period of three months. The following treatments were carried out: soil (control); soil + 50 t ha-1 of animal manure (E50); soil + 50 t ha-1 of animal manure + 30 L ha-1 of effective microorganisms (E50EM); soil + 30 t ha...
Nonlocal description of the nuclear interaction
Chamon,L. C.; Carlson,B. V.; Gasques,L. R.; Pereira,D.; De Conti,C.; Alvarez,M. A. G.; Hussein,M. S.; Cândido Ribeiro,M. A.; Rossi Jr.,E. S.Extensive systematizations of theoretical and experimental nuclear densities and of optical potential strengths extracted from heavy-ion elastic scattering data analyses at low and intermediate energies are presented. The energy-dependence of the nuclear potential is accounted for within a model based on the nonlocal nature of the interaction. The systematics indicates that the heavy-ion nuclear potential can b...
Micrurus spixii (PERUVIAN CORAL SNAKE) VENOM - PRELIMINARY BIOCHEMICAL AND ENZY...
REMUZGO,C.; ALVAREZ,M. P.; RODRIGUEZ,E.; LAZO,F.; YARLEQUE,A.Micrurus spixii venom was studied after fractionation by Sephadex G-100 SF gel filtration chromatography. Several enzymatic activities and biological effects were investigated in whole venom and fractions. The venom was resolved in four peaks in a range of about 73.2-10.7 kDa molecular weight. Alkaline phosphatase and acetylcholinesterase activities were found in peak I, and procoagulant activity was seen in pe...

Has time come for the genetic management of sea bass?
Volckaert, F.; Alvarez, M. C.; Argenton, F.; Bonhomme, F.; Chatain, B.; Colombo, L.; Castilho, Rita; Chevassus, B.; Gorshkova, G.; Kohler, M.Since 1980 the industrial production of European sea bass has risen considerably up to at least 18,000 MT in 1996 ( see also Josupeit, Aquaculture Europe 20(2):-12, 1995). This growth is remarkable since few were able to culture the species in the seventies. Several "classical" stages of development can be observed; they are typical of a rapidly expanding bioindustry.
Desnutrición infantil, coeficiente de desarrollo y su relación con el medio amb...
Alvarez,M. de la Luz; Concha,Ximena; Elordi,Margarita; Lamilla,Cecilia; Ramos,Carolina; Perez,PaulinaFueron estudiados los factores socioculturales que podrían estar influyendo en el desarrollo psicomotor normal del lactante desnutrido. La muestra consistió en 32 díadas madrelactante: 16 tenían CD normal (Grupo A) y 16 CD bajo lo normal (Grupo B) según el Test de Bailey aplicado a los lactantes recién ingresados a un Centro de Recuperación Nutricional. Los resultados muestran que había algunas diferencias en l...
