Lipid and glucose metabolism of broilers (Gallus gallus domesticus) experimentally infected with Eimeria acervulina Tyzzer, 1929 oocysts
Freitas, FLC;Almeida, KS;Machado, RZ;Machado, CR;
Revista Brasileira de Ciência Avícola , 2008, DOI: 10.1590/S1516-635X2008000300004
Abstract: lipid and glucose metabolism of 76 ten-day-old cobb male broilers, experimentally infected with eimeria acervulina, was studied for 30 days. birds were distributed in 2 groups: one infected with 1x106 e. acervulina sporulated oocysts, and the other inoculated with distilled water. pathological e biochemical liver changes were assessed, as well as plasma glucose concentrations and total cholesterol, hdl, ldl, vldl, fatty-acid, and triglyceride levels in the serum. the infected broilers presented hypoglycemia associated with a reduction in liver glycogen. in addition, these birds developed fatty liver, and there were changes in all lipid classes in the serum. lipid and glucose metabolism was dramatically changed in broilers experimentally infected with 1x106 e. acervulina oocysts.

Journal of Stem Cells and Regenerative Medicine , 2009,
Abstract: Age related bone loss is one of the most prevalent diseases in the elder population. The osteoblasts are the effectors cells of bone formation and regeneration. With the aging the osteoblasts become senescent reducing their ability to produce bone. Cellular replicative senescence is triggered by telomers shortening. Telomerase elongate the telomers length and maintain the cell proliferative capacity. Here, we demonstrated that the expression of human telomerase reverse transcriptase mediated by an adenovirus vector increases the levels of osteopontin and osteocalcin mRNA during the in vitro osteogenic differentiation of elderly human mesenchymal stem cells. Bone marrow human mesenchymal stem cells were obtained from old donors (>65 years) and induced to differentiate into osteoblasts for 14 days. The levels of mRNA of human telomerase reverse transcriptase, osteopontin and osteocalcin during the differentiation were assessed by semi-quantitative PCR before and during the differentiation on days 7 and 14. Infected cells showed 1.5 fold increase in telomerase expression. Also telomerized cells exhibit 1.5 fold increase in osteopontin and 0.5 fold increase in osteocalcin expression compared to primary osteoblasts isolated from the same donors. The transformed cells were not able to form tumours in NUDE mice.
Performance of IFAT, ELISA, direct parasitological examination and PCR on lymph node aspirates for canine visceral leishmaniasis diagnosis
Camargo, JB;Langoni, H;Troncarelli, MZ;Machado, JG;Lucheis, SB;Padovani, CR;
Journal of Venomous Animals and Toxins including Tropical Diseases , 2010, DOI: 10.1590/S1678-91992010000300007
Abstract: canine visceral leishmaniasis (cvl) is endemic in numerous brazilian regions. the greatest difficulty in controlling the disease is the diagnostic limitation. in the present study, the most common tests employed for visceral leishmaniasis diagnosis were compared: immunofluorescence antibody test (ifat), immunoenzymatic assay (elisa), direct parasitological examination and polymerase chain reaction (pcr). samples of lymph node aspirates and blood were collected from 100 dogs that lived in an endemic area (bauru city, s?o paulo state) and from 100 negative controls from a non-endemic area (botucatu city, s?o paulo state). specificity of both ifat and pcr was 100% whereas elisa was 99%. sensitivities were 97.77, 93.33 and 91.11% respectively for ifat, elisa and pcr.
Effect of the Contents and Form of Rabies Glycoprotein on the Potency of Rabies Vaccination in Cattle

Memórias do Instituto Oswaldo Cruz , 2002, DOI: 10.1590/S0074-02762002000200022
Abstract: one of the methods used for controlling cattle rabies in brazil consists of vaccination. sometimes, however, rabies occurs in cattle supposedly protected. since rabies vaccine batches are officially controlled by tests performed on laboratory animals, it is questionable whether the minimal mandatory requirements really correspond to immunogenicity in the target species. we have analyzed the association among potencies of rabies vaccines tested by the nih test, the contents and form (free-soluble or virus-attached) of rabies glycoprotein (g) in the vaccine batches, and the virus-neutralizing antibodies (vna) titers elicited in cattle. no correlation was found between g contents in the vaccine batches and the nih values, whatever the presentation of g. there was no correlation either between nih values and vna titers elicited in cattle. there was, however, a positive correlation (r = 0.8681; p = 0.0001) between the amounts of virion-attached g present in the vaccine batches and vna elicited in cattle. this was not observed when the same analysis was performed with total-glycoprotein or free-soluble glycoprotein. the study demonstrated that nih values can not predict the effect of the immunogen in cattle. on the other hand, the quantification of virus-attached rabies glycoprotein has a strong correlation with vna elicited in cattle.
Effect of oils sources on blood lipid parameters of commercial laying hens
Murata, LS;Ariki, J;Machado, CR;Silva, L da PG da;Rezende, MJM;
Revista Brasileira de Ciência Avícola , 2003, DOI: 10.1590/S1516-635X2003000300008
Abstract: the experiment was carried out to verify if total cholesterol, hdl-cholesterol and triacylglicerol plasma levels are affected when laying hens are fed rations containing different dietary oil sources. one hundred sixty 50 week-old hens, assigned to four treatments with five replicates using 8 hens per replicate were used. the experimental period was of 84 days divided in 3 cycles of 28 days each. in the last day of each cycle, blood samples of 2 hens per replicate were randomly choose and blood samples were collected. on the other hand, blood was also collected at 7 am, 11 am and 3 pm aiming to study the daily changes of these lipids. blood lipid parameters were not affected by different dietary oil sources (p > 0.05); however, hdl-cholesterol did change during the day, giving evidence that this lipid is indeed involved in the egg yolk formation.

Revista Brasileira de Ciência Avícola , 2003,
Abstract: The experiment was carried out to verify if total cholesterol, HDL-cholesterol and triacylglicerol plasma levels are affected when laying hens are fed rations containing different dietary oil sources. One hundred sixty 50 week-old hens, assigned to four treatments with five replicates using 8 hens per replicate were used. The experimental period was of 84 days divided in 3 cycles of 28 days each. In the last day of each cycle, blood samples of 2 hens per replicate were randomly choose and blood samples were collected. On the other hand, blood was also collected at 7 am, 11 am and 3 pm aiming to study the daily changes of these lipids. Blood lipid parameters were not affected by different dietary oil sources (p > 0.05); however, HDL-cholesterol did change during the day, giving evidence that this lipid is indeed involved in the egg yolk formation.

Abstract: The study investigated the Role of Information Technology (IT) in thecreation of wealth and poverty alleviation in Nigeria. The design of the studywas a descriptive survey, carried out at Nwafor Orizu College of Education,Nsugbe in Anambra State of Nigeria. One hundred and ninety three (193)respondents formed the sample population. Questionnaire was used for thecollection of data. Mean standard deviation and analysis of variance(ANOVA) at 0.05 level of significance was used for data analysis. Thefindings revealed that Information Technology (IT) is very imperative in thecreation of wealth and poverty reduction in Nigeria. Recommendations werealso made which include provision of capacity building, solar power andcreation of awareness among the communities on the use of InformationTechnology (IT), etc.
La bouche qui mange parle : langues, développement et interculturalité en Afrique noire
CR Abolou
African Anthropologist , 2008,
Abstract: Putting languages for development in Africa is an old ambition. Since the 1950s, There has been a pre-conceived notion about the relationship between language and development consisting of seeing the immediate or mediate impact on such diverse issues as: improving employment, competitiveness, labor market, agricultural production, etc. Ideas on African languages on /of development have already influenced problems of terminology and translation. Nowadays, the dominant theoretical positions and methodological praxis, inspired from globalization and linguistic and cultural diversity, recommend a circular pattern of development. In this model, the interface language/development appears as a black box that allows the tryptic terminology-knowledge-society to form the general framework of local and global development. This tryptic explodes ratiocinations on the “old” language/development couple as though there was on one side Language and on the other side Development in the fight for building ‘sustainable’ development in Black Africa. Mettre les langues au service du développement en Afrique noire est une ambition ancienne. Depuis les années 1950, la conception faite de la relation langue et développement était de voir l’incidence médiate ou immédiate sur les problèmes divers tels que : l’amélioration de l’emploi, la compétitivité, le marché du travail, la production agricole, etc. Les idées sur langues africaines en/de développement orientent déjà les problèmes de terminologie et de traduction. De nos jours, les postures théoriques et praxis méthodologiques dominantes s’inspirant des interprétations de la mondialisation et de la diversité linguistique et culturelle recommandent un modèle circulaire de développement. Dans ce modèle, l’interface Langue/Développement appara t comme une bo te noire qui autorise le tryptique terminologie-savoir-société pour former la trame signifiante du développement sur les plans local et global et pour exploser les ratiocinations du vieux couple langue et développement – comme s’il y avait d’un c té la langue et de l’autre le développement – aux fins de durabiliser le développement en Afrique noire.
Revisiting human behaviour in relation to HIV/AIDS
CR Bandawe
Malawi Medical Journal , 2002,
Abstract: It is widely recognised that human behaviour change is a key element in the fight against HIV/AIDS. The reality of the situation however is that the current approaches to instigating sexual behaviour change appear to have borne little fruit. This paper shall argue that in the fight against HIV/AIDS, a fundamental error is made in the numerous outreach programmes that exist within Malawi and elsewhere. This error is grounded in the assumptions that are made about how persons respond to the messages garnered to the control of the disease. Until this mistaken assumption is addressed, it is argued that no serious headway shall be made in the control of this disease, which threatens the very fabric of the Malawi nation. [Malawi Med J. Vol.14(2) 2002:27-28]
