Boff, Samuel;Graciolli, Gustavo;Boaretto, Amanda Galdi;Marques, Maria Rita;
Revista Brasileira de Entomologia , 2008, DOI: 10.1590/S0085-56262008000300025
Abstract: one of the ephemeral food sources that insects may use is the exudated gums from plants. in may 2005, in an area of cerrado from campo grande, mato grosso do sul, brazil, insects visiting an exudation structure of an individual of terminalia argentea mart & zucc (combretaceae) were observed. nineteen species were identified, mainly trigona branneri (cockerel) and mesembrinella bicolor (fabricius). all visitors had been observed collecting or ingesting the gum. visitation time and behavior of the most abundant species were reported. samples of exudates showed a low concentration of proteins and reducing sugars and high concentration of complex carbohydrate, allowing infer that visitors of t. argentea seek the gum a food resource of high molecular weight that contributes to the storage of energy reserves.

Fortes, Maria Rita Parise;Miot, Hélio Amante;Kurokawa, Cilmery Suemi;Marques, Mariangela Esther Alencar;Marques, Sílvio Alencar;
Anais Brasileiros de Dermatologia , 2011, DOI: 10.1590/S0365-05962011000300014
Abstract: paracoccidioidomycosis is the most prevalent systemic mycosis in latin america, among immunecompetent patients. it's caused by the dimorphic fungus paracoccidioiddes brasiliensis. investigations regarding its immunopathogenesis are very important in the understanding of aspects related to natural history, as the protective immunity, and the relationship between host and parasite; also favoring the knowledge about clinical patterns and the elaboration of therapeutic strategies. the disease clinical polymorphism depends, at least, of the immune response profile according to the tissue and blood released citokynes, resulting in tissue damage

PLOS ONE , 2009, DOI: 10.1371/journal.pone.0004945
Abstract: Background Dengue virus infection causes a wide spectrum of illness, ranging from sub-clinical to severe disease. Severe dengue is associated with sequential viral infections. A strict definition of primary versus secondary dengue infections requires a combination of several tests performed at different stages of the disease, which is not practical. Methods and Findings We developed a simple method to classify dengue infections as primary or secondary based on the levels of dengue-specific IgG. A group of 109 dengue infection patients were classified as having primary or secondary dengue infection on the basis of a strict combination of results from assays of antigen-specific IgM and IgG, isolation of virus and detection of the viral genome by PCR tests performed on multiple samples, collected from each patient over a period of 30 days. The dengue-specific IgG levels of all samples from 59 of the patients were analyzed by linear discriminant analysis (LDA), and one- and two-dimensional classifiers were designed. The one-dimensional classifier was estimated by bolstered resubstitution error estimation to have 75.1% sensitivity and 92.5% specificity. The two-dimensional classifier was designed by taking also into consideration the number of days after the onset of symptoms, with an estimated sensitivity and specificity of 91.64% and 92.46%. The performance of the two-dimensional classifier was validated using an independent test set of standard samples from the remaining 50 patients. The classifications of the independent set of samples determined by the two-dimensional classifiers were further validated by comparing with two other dengue classification methods: hemagglutination inhibition (HI) assay and an in-house anti-dengue IgG-capture ELISA method. The decisions made with the two-dimensional classifier were in 100% accordance with the HI assay and 96% with the in-house ELISA. Conclusions Once acute dengue infection has been determined, a 2-D classifier based on common dengue virus IgG kits can reliably distinguish primary and secondary dengue infections. Software for calculation and validation of the 2-D classifier is made available for download.

Leandro-Merhi, Vania Aparecida;Morete, Juliana Luisi;Oliveira, Maria Rita Marques de;
Arquivos de Gastroenterologia , 2009, DOI: 10.1590/S0004-28032009000300015
Abstract: context: a proper diagnosis of the nutritional status is of the utmost importance for prescribing enteral nutrition therapy in the hospital environment. objective: to assess nutritional status indicators of patients about to receive enteral nutrition therapy in a hospital unit. methods: this cross-sectional study examined the nutritional status of 100 adult patients before they were introduced to enteral nutrition therapy by calculating their body mass index . their height and weight were estimated by prediction formulas and laboratory indicators of nutritional and metabolic statuses. results: almost one-third (29%) of the patients were classified as malnourished according to their body mass index, while 80% of them had low albumin values (<3.2 g/dl). when patients were grouped according to body mass index, the distribution of the reasons for hospitalization did not differ between the groups. cardiovascular and pulmonary diseases prevailed as the main reasons for hospitalization. when patients were grouped according to body mass index and diagnosis upon admission, the rates of low albumin concentration, i.e., concentration below the reference value, did not differ between the groups. conclusion: the estimated body mass index was a specific indicator of nutritional status but lacked sensitivity. meanwhile, albumin was more sensitive, demonstrating that it is necessary to use many indicators in combination to diagnose nutritional status properly.

MIGLINO, Maria Angélica;SILVA, Rosana Marques;MACHADO, Marcia Rita Fernandes;
Brazilian Journal of Veterinary Research and Animal Science , 2001, DOI: 10.1590/S1413-95962001000200002
Abstract: we worked with 36 non-defined race female, adults cats, obtained from donations. in 30 of these animals was inject in their arterial vases latex neoprene 650, red-faced, for the systematical study of the origin and distribution of the arteries leading to the uterus and uterine tube. in 6 of these animals was utilized injection of vinil acetat, spaltholz diafanization method and radiography with contrast, to illustration our lead labor. we observed that the vases that lead to the uterine tube and to the uterus come from the ovaries arteries, uterine arteries and their collateral's (caudal vesical artery and urethral branch). in all observations (100%), the ovaric artery has its origin in the aorta artery and emits one branch in 56.67% of the observations to the uterine tube and in 43.33% of the times to the uterine horn and uterine tube. in all observations (100%), the uterine artery has its origin in the vaginal artery, as a unique vase, and emits 1-4 branches to the uterine cervix, 1-2 branches to the cervix and uterine body, 1-4 branches to the uterine body, 1-19 branches to the uterine horn, 1 branch to the uterine horn and uterine tube and 1 branch to the uterine tube. the caudal vesical artery and the urethral branch helps at irrigation of the cervix and the uterine body, when these ones go to the urethra and bladder, respectively. we're found anastomoses between the branches of the uterine artery and between these and the branches of the ovaric artery.
