Breeding potential of maize composite Isanao VF1 in small spacing in the second growing season

The purpose of this study was to verify the breeding potential of the maize composite Isanao VF1 in the second growing season. One hundred and fifty half-sib progenies were evaluated of spacing of 0.45 m, densities of 57,778 and 80,000 plants ha(-1), in a randomized block design with three replications. Gains of 16.0 and 19.2% were estimated for grain Yield, H. I and 10.5% for prolificacy and 12.3 and 12.9% for ear height, respectively, at 57,778 and 80,000 plants ha(-1). The heritabilities for plant height, ear height and grain yield were 65.2 and 61.3%, 64.3 and 66.9% and 53.5 and 63.3%, respectively, confirming the potential for breeding at both densities. The absence of progeny by density interaction indicates that no further selection programs are necessary. The occurrence of segregation for modifier genes for height suggests stabilizing selection based on ear height.

A eficácia do milnaciprano em pacientes ambulatoriais com transtorno depressivo maior não respondedores ao tratamento com ISRSs: um estudo aberto de 12 semanas

CONTEXTO: O objetivo deste estudo é avaliar a eficácia do milnaciprano em pacientes ambulatoriais com depressão maior grave que não respondem em tempo e em dosagem adequados à terapia com ISRSs. MÉTODOS: Um estudo aberto multicêntrico com a duração de 12 semanas foi elaborado para avaliar a eficácia do milnaciprano após falha em um experimento com ISRS. Remissão completa (HAMD-17 < 8) foi o desfecho principal. Os desfechos secundários foram resposta (HAM > 50%), CGI e avaliação da qualidade de vida (WHOQOL-Bref). RESULTADOS: O escore HAMD-17 médio da amostra foi de 27 (7,2). As taxas de remissão com o milnaciprano foram de 17,5%, e as de resposta, 61,3%. Na linha de base, 70,9% dos pacientes foram classificados como gravemente sintomáticos. Ao final do tratamento, 48,1% dos pacientes foram classificados como normais assintomáticos ou sintomáticos limítrofes e 20,2% eram moderadamente sintomáticos. Além disso, os quatro domínios do WHOQOL-Bref, um instrumento genérico de mensuração de qualidade de vida, apresentou diferenças clínicas e estatísticas: CONCLUSÃO: Nossos resultados sugerem que o milnaciprano é uma possível opção para pacientes que não respondem a ISRSs. Uma vez que não há evidências na literatura de um antidepressivo que seja a melhor opção quando um ISRS falha, o uso do milnaciprano deveria ser considerado em casos de pacientes com depressão severa.

Effects of dietary trace mineral sources and levels fed to layers in their second laying cycle on the quality of eggs stored at different temperatures and for different periods

This study aimed at evaluating the effects of trace mineral levels and sources supplemented to diets fed to semi-heavy layers in their second laying cycle on the quality of eggs stored for 14 days at different temperatures. The experimental diets consisted of the inclusion of inorganic trace minerals (T1 - control: 100% ITM) and five supplementation levels of organic trace minerals (carboaminophopho chelates) (110, 100, 90, 80, and 70% OTM). Trace mineral inclusion levels (mg/kg feed) were: T1: control - 100% ITM: Zn (54), Fe (54), Mn (72), Cu (10), I (0.61) Se (0.3); T2 - 110% OTM: Zn (59.4), Fe (59.4), Mn (79.2), Cu (11.88), I (1.21) Se (0.59); T3 - 100%: OTM: Zn (54), Fe (54), Mn (72), Cu (10.8), I (1.10) Se (0.54); T4 - 90% OTM: Zn (48.6), Fe (48.6), Mn (64.8), Cu (9.72), I (0.99) Se (0.49); T5 - 80% OTM: Zn (43.2), Fe (43.2), Mn (57.6), Cu (8.64), I (0.88), Se (0.43); T6 - 70% OTM: Zn (37.8), Fe (37.8), Mn (50.4), Cu (7.56), I (0.77) Se (0.38). A completely randomized experimental design in a split-plot arrangement with 60 treatments of four replicates each was applied. The combination of six diets versus storage temperature (room or under refrigeration) was randomized in plots, whereas the sub-plots consisted of storage times (0, 3, 7, 10, and 14 days). Data were submitted to analysis of variance of a model in slip-plots in time using the software package SAS (2000) at 5% probability level. It was concluded that 70% OTM supplementation can be used with no damage to egg quality, independently from storage temperature or time. The quality of refrigerated eggs stored up to 14 days is better than those stored at room temperature.

Effect of organic mineral supplementation on the egg quality of semi-heavy layers in their second cycle of lay

This study was carried out to evaluate the effects of dietary trace mineral levels and sources on egg quality parameters of second-cycle semi-heavy layers. A number of 360 72-week-old layers were submitted to forced molting. Upon return of lay (83 weeks of age), birds were distributed according to a completely randomized experimental design of six treatments with six replicates of 10 birds each. The control treatment consisted of 0.10% dietary supplementation of trace minerals from inorganic sources, which was proportionally replaced by five levels (110, 100, 90, 80, 70%) of an organic trace mineral supplement containing 30, 30, 40, 6, 0.61, and 0.3 g/kg product of Zn, Fe, Mn, Cu, I, and Se, respectively. All diets contained equal protein, energy, and amino acid levels. Every 28 days of the experimental period (112 days) four eggs per replicate were collected for egg quality evaluation. The following parameters were evaluated: specific gravity, yolk, albumen and eggshell percentages, yolk index, Haugh units, and eggshell thickness and breaking strength. One sample per replicate, consisting of the pool of the yolks of three eggs collected at the end of each experimental period, was used to assess protein and mineral (Ca, P, Cu, Fe, Mn, and Zn) contents. The results were submitted to ANOVA, and means to the test of Tukey at 5% significance level. The evaluated trace mineral levels and sources did not influence any of the studied egg quality parameters. It was concluded that reducing organic trace mineral supplementation in up to 70% relative to 100% inorganic trace mineral supplementation does not affect egg parameters and therefore, can be applied to the diet of semi-heavy layers in their second cycle of lay.

Forced-Molting methods and their effects on the performance and egg quality of japanese quails (Coturnix japonica) in the second laying cycle

The experiment was carried out in the experimental poultry house of the Research and Development Unit of Brotas of Agência Paulista de Tecnologia dos Agronegócios do Centro-Oeste, SP, Brazil. The objective of the study was to evaluate the performance of Japanese quails submitted to forced molting aiming at optimizing the use of the same quail flock by promoting a second laying cycle. A total number of 400 67-day-old Japanese quails in lay, previously submitted to 14 days of forced molting, was distributed in a completely randomized experimental design into five treatments (T1= not submitted to forced molting, T2= 03 days of fasting + fed ad libitum, T3= 01 days of fasting + 13 days of feed restriction, T4= 02 days of fasting + 12 days of feed restriction, and T5= 03 days of fasting + 11 days of feed restriction. Feeds were contained equal nutrient levels, and were formulated according to NRC (1994) recommendations. There were significant differences among the studied treatments. Although the treatment of 3 days of fasting followed by ad libitum feeding resulted in lower egg weight, it promoted better lay percentage, egg mass, and feed conversion ratios (FCR/dz and FCR/kg). on the other hand, 3 days of fasting followed by restricted feeding resulted in higher feed intake and worse feed conversion ratios (FCR/dz and FCR/kg). When birds were not submitted to forced molting, they presented lower lay percentage and egg mass.

First Report on Rotenoids as Neurotoxic Principles of Seeds from Aeschynomene indica (Leguminosae)

Toxic principles from seeds of Aeschynomene indica collected in Brazil were analyzed. Dalpanol, 12 alpha-hydroxydalpanol and 11-hydroxydalpanol were identified using (1)H NMR in A. indica for the first time. 11-hydroxydalpanol has not been previously reported in the existing literature. Furthermore these rotenoids are likely the toxic principles that cause neurological signs in mice.

Malnutrition in the second year of life and psychosocial care: a case-control study in an urban area of Southeast Brazil

O objetivo do estudo foi identificar e medir a presença de associação entre cuidado psicossocial e desnutrição. Realizou-se estudo caso-controle incluindo 101 crianças desnutridas (peso/idade < percentil 5 do padrão NCHS/OMS), com idades entre 12 e 23 meses, que foram comparadas a 200 controles eutróficos (peso/ idade > percentil 25) em termos de sua exposição a uma série de comportamentos maternos indicadores da qualidade de seu cuidado psicossocial. Criou-se um escore de cuidado psicossocial, variando de 0 a 14, de acordo com o número de comportamentos maternos desejáveis não observados: quanto maior o escore, pior a qualidade do cuidado psicossocial. Mediante análise de regressão logística verificou-se maior risco de desnutrição para as crianças no 2º e 3º tercis do escore de cuidado psicossocial. Esta associação foi modificada pela renda per capita. Após ajustes para possíveis confundidores, nas crianças dos estratos superiores de renda não houve associação entre cuidado psicossocial e desnutrição. Para as crianças com nível mais baixo de renda, pior cuidado psicossocial dobrou o risco de desnutrição (OR = 7,26; IC95%: 2,42-21,82) em relação àquele associado apenas à baixa renda (OR = 3,08; IC95%: 1,28-7,42).

Genetic parameters for milk yield, age at first calving and interval between first and second calving in milk buffaloes

Genetic parameters for the relation between the traits of milk yield (MY), age at first calving (AFC) and interval between first and second calving (IBFSC) were estimated in milk buffaloes of the Murrah breed. In the study, data of 1578 buffaloes at first lactation, with calvings from 1974 to 2006 were analyzed. The MTDFREML system was used in the analyses with models for the MY, IBFSC traits which included the fixed effects of herd-year-season of calving, linear and quadratic terms of calving age as covariate and the random animal effects and error. The model for AFC consisted of the herd-year-season fixed effects of calving and the random effects of animal and error. Heritability estimates MY, AFC and IBFSC traits were 0.20, 0.07 and 0.14, respectively. Genetic and phenotypic correlations between the traits were: MY and AFC = -0.12 and -0.15, MY and IBFSC = 0.07 and 0.30, AFC and IBFSC = 0.35 and 0.37, respectively. Genetic correlation between MY and AFC traits showed desirable negative association, suggesting that the daughters of the bulls with high breeding value for MY could be physiological maturity to a precocious age. Genetic correlation between MY and IBFSC showed that the selection of the animals that increased milk yield is also those that tend to intervals of bigger calving.

A second mutation in the methylenetetrahydrofolate reductase gene and the risk of venous thrombotic disease

We assessed the effect of a recently described mutation in the MTHFR gene (1298 A --> C) on the risk of deep venous thrombosis (DVT) by determining its prevalence in 190 patients with verified DVT and in age-, race- and gender-matched controls. MTHFR 1298 A --> C was found in 42.1% of patients and in 41.1% of controls. The OR for venous thrombosis was 1.07 (95% CI 0.70-1.65) for heterozygotes and 0.83 (95% CI 0.33-2.08) for homozygotes. The OR for the factor V Leiden (FVL) mutation was 3.40 (95% CI 1.22-9.48), for FII 20210 G --> A was 5.22 (95% CI 1.12-24.2) and for MTHFR 677 C --> T, 1.24 (95% CI 0.82-1.87). No significant increased risk for venous thrombosis was found when MTHFR 1298 A --> C was coinherited with FVL (OR 2.85, 95% CI 0.88-9.23), FIT 20210 G --> A (OR 7.19, 95% CT 0.87-59.4) or MTHFR 677 C --> T (OR 1.44, 95% CT 0.71-2.92). These data do not support a critical role of MTHFR 1298 A --> C in the predisposition to DVT.

Second, primary tumours in patients with mouth cancer

Over the last decades, technical-scientific advances of oncology have brought about an increased survival rate for cancer patients. As a result, oncologists have detected an increased number of patients presenting with other neoplasms. This research aimed to analyze factors related to demography and to the anatomic site in patients having a FPT of the mouth who developed a SPT. Medical charts of 848 patients neoplasm admitted for treatment at the Head and Neck Surgery Department of the Hospital do Cancer, Antonio Candido Camargo, Brazil, from January of 1984 to December, were analysed. of these, 12 6 developed a SPT. 49.21 % were from 51 to 65 years of age, while 83.33% were of the male gender and Caucasian. Regarding FPT site 38.89% were of the tongue, and 28.5% were of the floor of the mouth. The esophagus, excepting skin (13.49%), was more often subject to SPT (11.9%), of these 74.6% were metachronic, 15.87% simultaneous and 9.52% synchronous.
