Doses de nitrogenio no crescimento e producao inicial do mamoeiro, sob gotejamento, no litoral piauiense.

Com objetivo de avaliar o efeito de doses de nitrogenio no crescimento e producao inicial do mamoeiro irrigado, instalou-se um experimento na estacao experimental da Embrapa Meio-Norte, em Parnaiba, PI, em solo pertencente a Unidade de Mapeamento Areias Quartzosas alicas e distroficas A fraco e moderado fase caatinga litoranea, relevo plano.bitstream/item/83331/1/CT970001.pd

Efeitos genéticos e de ambiente para características de crescimento em ovinos Santa Inês no Estado do Ceará.

Registros de 1.335 ovinos da raça Santa Inês, nascidos entre 1984 e 1998, no rebanho experimental do Centro Nacional de Pesquisa de Caprinos (Embrapa caprinos) e criados em regime semi ? intensivo, foram utilizados para estimar as herdabilidades direta e materna de pesos corporais em diferentes idades. Os componentes de variância e as herdabilidades foram estimados pelo método da Máxima Verossimilhança Restrita - REML, utilizando o algoritmo livre de derivadas (DFREML), com modelo animal uni-característica e o aplicativo Multiple Trait Derivative-Free Restricted Maximum Likelihood (MTDFREML). No modelo estatístico foram incluídos os efeitos aleatórios genéticos direto e materno, de ambiente permanente e o erro, além dos efeitos fixos de sexo, estação e ano de nascimento, tipo de nascimento e da covariável peso da ovelha ao parto. As herdabilidades direta e materna foram de baixa magnitude, variando de 0,11 a 0,21, o que indicaram baixa variabilidade genética e apontam para a necessidade de introdução de novos reprodutores para o melhoramento genético do rebanho. Genetic and enviromental effects for growth traits in Santa Inês hair sheep at Ceará State, Brazil. Abstract - Files from 1,335 sheep of Santa Inês breed, born between 1984 and 1998, in the experimental herd of the National Goat Research Center ? Embrapa caprinos and raised under semi intensive pasture condition were used to estimate direct and maternal heritability for body weight at different ages. Variance components and heritability were estimated by Restricted Maximum Likelihood methodology using a single trait animal model and the software MTDFREML. The statistical model included direct and maternal genetic effects and permanent environmental random effects, as well as the fixed effects of sex, season and year of birth, birth type and covariate weight of the dam. The direct and maternal heritability, varied from 0.11 to 0.21. The direct and maternal heritability suggest small genetic variability and indicate a necessity of inserting new rams for genetic improvement of the herd

Candidemia in Acute Leukemia Patients

Fungal infections are an important cause of morbidity and mortality in patients with acute leukemia (AL). Candidemia, once rare, is now a common nosocomial infection because of the intensity of chemotherapy, prolonged neutropenia, administration of broad-spectrum antibiotics and use of central venous catheters (CVC). We retrospectively identified patients treated for AL from 6/86 to 6/95 who also had candidemia. We describe 28 patients (incidence 6.3%) with a median age of 39 years, 24 of whom were on remission induction and 4 on postremission chemotherapy. All patients had CVC and empiric antimicrobial therapy, 4 had been given prophylactic antifungal drugs, and 2 had parenteral nutrition. Neutropenia was profound (median leukocyte nadir 200/microliters, median duration 19 days). Candida was isolated in blood cultures 10 days (median) after the start of neutropenia. The clinical presentation included fever (100%), respiratory symptoms (71.4%), skin lesions (39.2%) and septic shock (17.8%). Amphotericin B was given to 17 patients and liposomal amphotericin to 5 patients. Infection resolved in 18 patients (64.2%). 10 of whom were in complete remission. Mortality from candidemia was 17.8% (5/28). In conclusion, fungal infections are responsible for death in a significant number of patients. In our series treatment success was related to its rapid onset and to the recovery of neutropenia
