Topographic characterisation of dental implants for commercial use

To characterize the surface topography of several dental implants for commercial use. Dental implants analyzed were Certain (Biomet 3i), Tissue Level (Straumann), Interna (BTI), MG-InHex (MozoGrau), SPI (Alphabio) and Hikelt (Bioner). Surface topography was ascertained using a confocal microscope with white light. Roughness parameters obtained were: Ra, Rq, Rv, Rp, Rt, Rsk and Rku. The results were analysed using single-factor ANOVA and Student-Neuman-Keuls(p<0.05) tests. Certain and Hikelt obtained the highest Ra and Rq scores, followed by Tissue Level. Interna and SPI obtained lower scores, and MG-InHex obtained the lowest score. Rv scores followed the same trend. Certain obtained the highest Rp score, followed by SPI and Hikelt, then Interna and Tissue Level. MG-InHex obtained the lowest scores. Certain obtained the highest Rt score, followed by Interna and Hikelt, then SPI and Tissue Level. The lowest scores were for MG-InHex. Rsk was negative (punctured surface) in the MG-InHex, SPI and Tissue Level systems, and positive (pointed surface) in the other systems. Rku was higher than 3 (Leptokurtic) in Tissue Level, Interna, MG-InHex and SPI, and lower than 3 (Platykurtic) in Certain and Hikelt. The type of implant determines surface topography, and there are differences in the roughness parameters of the various makes of implants for clinical use

Efecto de diferentes niveles de consumo de pasto elefante (Pennisetum purpureum, Schum var. Cameroon) durante la recría de caprinos

The intake of the ration (CR), dry matter (CMS), metabolizable energy (CEM), ether extract (CEE), crude protein (CPB), neutral detergent fibre (CFDN), acid detergent fibre (CFDA), organic matter (CMO), and also total weight gain (GPT), diary weight gain (GPD), feed conversion (CA) and feed efficiency (EA), were determinates to evaluate the effect of the inclusion of elephant-grass hay (FCE) in complete rations. Twenty-seven goats of breed Saanen were used (15 males no castrated and 12 females) in the phase of growing phase, with 118 days of age and medium alive weight of 15.35 kg, fed with diets containing 30, 45 and 60 % of inclusion of elephant-grass hay, distributed in entirely randomized design in factorial scheme 3×2 (three treatments and two sexes), being five males and four females for treatment. For CEM and CEE, there was a decreasing lineal effect with the increase in the levels of inclusion of FCE. Though, for CFDN and CFDA the behaviour was increase linearly. GPT presented significant effect for the effect sex (P&lt;.01). It was verified that as the fibre levels went increasing, GPT went decreasing. The inclusion of hay of Grass-elephant in diets for goats in the growing phase, it didn't influence the intake of dry matter for the males. The level of inclusion of hay of Grass-elephant of 60 % provided a better relationship cost/benefice for the males in growing phase, while for the females the level of 45 % would be the most suitable

Influência do sexo do animal e do sistema de produção nas características de carcaça de caprinos da raça Blanca Serrana Andaluza Influence of animal gender and production system on the carcass characteristics of goats of the Blanca Serrana Andaluza breed

Objetivou-se avaliar a influência do sexo e do sistema de produção nas características de carcaça de caprinos da raça Blanca Serrana Andaluza. Foram utilizados 31 animais, 12 machos e 19 fêmeas, distribuídos nos sistemas de produção intensivo (15 animais) e extensivo (16 animais). Não foi observada diferença no desempenho, no peso de carcaça e no escore corporal entre os sexos nem entre os sistemas de produção, contudo, os rendimentos de carcaça quente e fria foram maiores nos animais terminados em confinamento. As medidas de carcaça não diferiram entre os sistemas de produção, exceto o comprimento interno, que foi maior nos animais criados no sistema intensivo. O percentual dos não-constituintes da carcaça sofreu pouca variação em relação ao sexo e aos sistemas de criação avaliados. As maiores proporções de gordura perirrenal foram encontradas nas fêmeas e nos animais produzidos em confinamento. Pouca variação foi observada para os cortes paleta, pescoço e serrote, embora o percentual de perna tenha sido maior nos animais produzidos a pasto. O sistema extensivo, predominantemente usado por criadores da raça Blanca Serrana Andaluza na Espanha, permite obter carcaças com características similares às dos animais criados em confinamento e, em virtude da significativa redução dos custos com alimentação, obtida com os animais exclusivamente a pasto, pressupõe-se que esse sistema seja mais economicamente viável.The objective of this study was to evaluate the influence of gender and production system on the carcass characteristics of Blanca Serrana Andaluza goats. Thirty-one animals were used, 12 males and 19 females, distributed in intensive (15 animals) and extensive (16 animals) production systems. No difference was observed in performance, carcass weight and body score between the gender or production system but the hot and cold carcass yields were greater for the animals finished in a feedlot. The carcass measurements did not differ, except for internal carcass length, which was longer for the animals under the intensive system. The percentage of non-constituent carcass components showed little variation for gender or the different rearing systems studied. The greatest proportions of perirenal fat were found in females and in the animals produced in feedlot. Little variation was observed for the shoulder, neck and breasts cuts, but the percentage of leg was greater in the animals produced in pasture. The extensive system, commonly used by Blanca Serrana Andaluza breeders in Spain, resulted in carcasses with characteristics similar to the animals reared in feedlot, and because of the substantial reduction in feeding costs obtained with animals exclusively on pasture, it is assumed to be the most economically viable system

Use of active management of the third stage of labour in seven developing countries

OBJECTIVE: To document the use of active management of the third stage of labour for preventing postpartum haemorrhage and to explore factors associated with such use in seven developing countries. METHODS: Nationally representative samples of facility-based deliveries were selected and observed to determine the use of active management of the third stage of labour and associated factors. Policies on active management were assessed through document review and interviews with relevant professionals. FINDINGS: Use of a uterotonic during the third or fourth stages of labour was nearly universal. Correct use of active management of the third stage of labour was found in only 0.5% to 32% of observed deliveries due to multiple deficiencies in practice. In every country except Indonesia, policies regarding active management were conflicting. CONCLUSION: Developing countries have not targeted decreasing postpartum haemorrhage as an achievable goal; there is little use of active management of the third stage of labour, and policies regarding such management often conflict. Studies are needed to identify the most effective components of active management so that the most efficient package of practices can be promoted

Polymeric antigen BLSOmp31 formulated with class B CpG-ODN in a nanostructure (BLSOmp31/CpG-ODN/Coa-ASC16) administered by parenteral or mucosal routes confers protection against Brucella ovis in Balb/c mice

Previously, we demonstrated that the chimera BLSOmp31 formulated in chitosan microspheres or Poloxamer407-Chitosan administered via the nasal and the ocular mucosa conferred partial protection in sheep against B. ovis. In this work, we tested a new delivery system for mucosal immunization with BLSOmp31 in the murine model to improve the efficacy of previously used formulations. First, we evaluated the protective efficacy against B. ovis induced by BLSOmp31 administered by the subcutaneous route using either BLSOmp31 alone, co-administered with immunostimulatory synthetic oligodeoxynucleotides containing unmethylated cytosine-guanine motifs (CpG-ODN) or with CpG-ODN in a nanostructure called Coa-ASC16 compared with BLSOmp31 emulsified in Incomplete Freund Adjuvant. Then, we evaluated the protection conferred by the best performing formulation (BLSOmp31/CpG-ODN/Coa-ASC16) administered by both subcutaneous and ocular routes. BLSOmp31/CpG-ODN/Coa-ASC16 injected subcutaneously did not induce higher IgG antibody levels compared to BLSOmp31 alone or BLSOmp31/CpG-ODN but it did stimulate a mixed immune Th1-Th2 response with the highest levels of IFN-ɣ and conferred significant protection against the B. ovis challenge. Although ocular instillation of BLSOmp31/CpG-ODN/Coa-ASC16 showed a similar degree of protection compared to the parenteral route (3.66 and 3.60 logs of protection, respectively), it induced lower levels in serum of specific IgG (with mixed IgG1/IgG2a) and IgA antibodies and, less IFN-ɣ and IL-4 than the subcutaneous route. No antibodies were detected in vaginal lavages or saliva. Fecal antigen-specific IgA was slightly higher in mice immunized with BLSOmp31/CpG-ODN/Coa-ASC16 subcutaneously compared with the ocular route. These results indicate that BLSOmp31/CpG-ODN/Coa-ASC16 was a safe and effective vaccine against B. ovis in mice.Fil: Moran, María Celeste. Consejo Nacional de Investigaciones Científicas y Técnicas.

Pneumocystis

Introduction: Specific environmental factors may play a role in the development of Pneumocystis pneumonia (PCP) in HIV-positive patients. The aim of this study was to estimate the PCP incidence and mortality in hospitalized HIV-positive patients in Spain during the combination antiretroviral therapy (cART) era (1997 to 2011), as well as to analyze the climatological factors and air pollution levels in relation to hospital admissions and deaths. Methods: We carried out a retrospective study. Data were collected from the National Hospital Discharge Database and the State Meteorological Agency of Spain. A case-crossover analysis was applied to identify environmental risk factors related to hospitalizations and deaths. For each patient, climatic factors and pollution levels were assigned based on readings from the nearest meteorological station to his or her postal code. Results: There were 13,139 new PCP diagnoses and 1754 deaths in hospitalized HIV-positive patients from 1997 to 2011. The PCP incidence (events per 1000 person-years) dropped from 11.6 in 1997 to 2000, to 5.4 in 2004 to 2011 (p<0.001). The mortality (events per 10,000 person-years) also decreased from 14.3 in 1997 to 2000, to 7.5 in 2004 to 2011 (p<0.001). Most hospital admissions and deaths occurred in the winter season and the fewest occurred in the summer, overlapping respectively with the lowest and highest temperatures of the year in Spain. Moreover, lower temperatures prior to PCP admission, as well as higher concentrations of NO2 and particulate matter up to 10 m in size (PM10) at the time of admission were associated with higher likelihoods of hospital admission due to PCP when two weeks, one month, 1.5 months or two months were used as controls (p<0.01). Furthermore, higher concentrations of ozone at one month (p=0.007), 1.5 months (p<0.001) and two months (p=0.006) prior to admission were associated with higher likelihoods of hospital admission with PCP. For PCP-related deaths, lower temperatures prior to admission and higher concentrations of atmospheric PM10 at the time of admission were related to higher likelihood of death when two weeks, one month and 1.5 months were used as controls (p<0.05). Conclusions: PCP was a significant health problem in the cART era (1997 to 2011), and PCP epidemiology was adversely influenced by colder climatological factors and higher ambient air pollution levels
