Estandarización de técnicas de extracción de ADN en sementales porcinos para evaluar la frecuencia de los genes ESR y PLRL con PCR-RFLP
Provedor de dados: 32
Autores: Dolores Ramos Eva.
Con el objeto de estandarizar y perfeccionar una técnica de extracción y purificación  de ADN a partir de sangre, semen y pelo de porcinos, se obtuvieron muestras de   35 sementales de línea materna Yorkshire y Landrace, en los cuales se valoró la  frecuencia de los genes ESR y PRLR  mediante PCR-RFLP. La extracción de ADN  a partir de sangre y semen únicamente se estandarizaron. El pelo de sementales  fue la mejor opción para obtener una alta cantidad y calidad de ADN. Se identificó la  frecuencia de dos genes relacionados con prolificidad: Receptor de Prolactina  (PRLR) y Receptor de Estrógeno (ESR); en su amplificación se utilizó PCR-RFLP´s  y se identificaron los genotipos. En esta  identificación se utilizó la enzima Alu I para  PRLR y Pvu II para...

Quantitative trait loci mapping of pubescence density and flowering time of insect-resistant soybean (Glycine max L. Merr.)
Provedor de dados: 74

Analysis of antibiosis resistance to common cutworm (Spodoptera litura Fabricius) in soybean (Glycine max (L.) Merr.) has progressed significantly, but the immediate cause remains unknown. We performed quantitative trait loci (QTL) analysis of pubescence density and plant development stage because these factors are assumed to be the immediate cause of resistance to cutworm. The QTLs for pubescence appeared to be identical to the previously detected the Pd1 and Ps loci controlling pubescence density. We found no candidate loci for flowering time QTLs, although one could be identical to the gene governing the long-juvenile trait or to the E6 loci controlling maturity. None of the QTLs overlapped with the QTLs for antibiosis resistance.

Assessing the efficacy of hair snares as a method for noninvasive sampling of Neotropical felids
Provedor de dados: 103
Autores: Portella,Tatiana P.; Bilski,Diego R.; Passos,Fernando C.; Pie,Marcio R.
Hair snares have been used in North and Central America for a long time in assessment and monitoring studies of several mammalian species. This method can provide a cheap, suitable, and efficient way to monitor mammals because it combines characteristics that are not present in most alternative techniques. However, despite their usefulness, hair snares are rarely used in other parts of the world. The aim of our study was to evaluate the effectiveness of hair snares and three scent lures (cinnamon, catnip, and vanilla) in the detection of felids in one of the largest remnants of the Brazilian Atlantic Forest. We performed tests with six captive felid species - Panthera onca (Linnaeus, 1758), Leopardus pardalis (Linnaeus, 1758), L. tigrinus (Schreber, 1775),...

Multivariate optimization of a method for antimony determination by hydride generation atomic fluorescence spectrometry in hair samples of patients undergoing chemotherapy against Leishmaniasis
Provedor de dados: 42
Autores: CARDOZO,MANUELLE C.; CAVALCANTE,DANNUZA D.; SILVA,DANIEL L.F.; SANTOS,WALTER N.L. DOS; BEZERRA,MARCOS A.
ABSTRACT A method was developed for determination of total antimony in hair samples from patients undergoing chemotherapy against Leishmaniasis based on the administration of pentavalent antimonial drugs. The method is based on microwave assisted digestion of the samples in a pressurized system, reduction of Sb5+ to Sb3+ with KI solution (10% w/v) in ascorbic acid (2%, w/v) and its subsequent determination by hydride generation atomic fluorescence spectrometry (HG-AFS). The proportions of each component (HCl, HNO3 and water) used in the digestion were studied applying a constrained mixtures design. The optimal proportions found were 50% water, 25% HNO3 and 25% HCl. Variables involved in the generation of antimony hydride were optimized using a Doehlert...

Diffuse heterotopic hair in a canine uterus: case report
Provedor de dados: 45
Autores: Malm,C.; Serakides,R.; Silva,J.F.; Nascimento,E.F.; Boeloni,J.N.; Viana,F.A.B.; Souza,E.M.; Ocarino,N.M.
The present report describes the clinical and pathological findings related to diffuse heterotopic hairs associated with pseudo-placentational endometrial hyperplasia in a canine uterus. Macroscopically, the uterus was intensely enlarged and thicker, and the endometrial surface was irregular and covered with black hairs similar to the hairs of the bitch. Histologically, heterotopic hairs associated with pseudo-placentational endometrial hyperplasia were observed.

Evaluation of Lead and Copper content in hair of workers from oil product distribution companies in Iraq
Provedor de dados: 60
Autores: Jaccob,Ausama Ayob.
Serious health consequences can occur not only from acute exposure to environmental toxicants, but also from chronic exposures to minute quantities. Petroleum substances are widely distributed and used in huge amount, mainly as fuels. A total number of 45 males aged between 20 and 45 years participated in this study. The participants were divided in to two groups: The first group of 25 subjects worked at least 8hours/day in different oil product distribution companies in both Basrah and Thiqar Governorates-Iraq. The second group (control group) of 20 healthy individuals with age and weight matched with the test group and lived far away from hazardous exposure. Heavy metals levels in hair were measured by Atomic Absorption Spectrophotometer. Statistical...
