| The objective of this study was to evaluate the chemical composition and fatty acid profile of meat from Santa Inês, Dorper × Santa Inês, and undefined-breed lambs finished in a feedlot system according to two forage:concentrate ratios (50:50 and 20:80) in the diet. Overall, 54 non-castrated animals were used (with an average initial weight of 23±1.5 kg at 150 days old) and were slaughtered when they reached 36 kg of live weight or 63 days of confinement. Diets with high concentrate levels favored meat production with higher protein content. Among the saturated fatty acids, only heptadecanoic (C17:0) and arachidic acids (C20:0) differed among the treatments. The amount of oleic acid detected in the meat ranged from 49.2 to 51.9 g/100 g, making this one the... |

| Red clover (Trifolium pratense L.) is one of the most important temperate legume species, used to lessen the lack of forage during the critical fall-winter period in Rio Grande do Sul, RS, Brazil. However, its utilization has been restricted mainly because of its lack of persistence. This work evaluates the dry matter yield and persistence of red clover half-sib progenies in two physiographic regions of RS: "Depressão Central", in Eldorado do Sul and "Encosta Superior do Nordeste", in Veranópolis. Experiments were carried out for two growing seasons and results were compared to two red clover commercial checks, Qüiñequeli and Estanzuela 116. The region of Veranópolis was more adequate for red clover forage production, enabling better yield and persistence.... |

| In order to estimate genetic diversity among starting materials and breeding strains of caraway, a collection of 17 accessions from botanical gardens in Europe, two cultivars ‘Rekord’ and ‘Kończewicki’, and four own breeding strains were analyzed by RAPD-PCR. The representative samples, each of five individual plants of accession, cultivar or strain, were taken from young rosette leaves. Forty of Genset Oligos RAPD primers were used for analysis and eight of them produced clear and reproducible banding patterns. In total, 62 banding patterns were obtained revealing 23 polymorphic bands, whereas the number of polymorphic bands ranged from two to four for one primer. The GS12 and GS43 primers generated two polymorphic bands, while each of the GS8, GS21,... |

| O uso de híbridos e genótipos de milho resistentes aos nematóides formadores de galhas em sistemas de rotação de culturas mantém sua população em níveis baixos, diminuindo as perdas e possibilitando, posteriormente, o uso de genótipos mais suscetíveis. No presente trabalho, foi avaliada a resistência de 18 genótipos de milho ao parasitismo de M. paranaensis e a M. incógnita raça 1 em casa-de-vegetação. As plantas foram inoculadas com 5.000 ovos e eventuais juvenis dos respectivos nematóides. O delineamento utilizado foi inteiramente ao acaso, com dez repetições para cada tratamento com os nematóides e cinco repetições para a testemunha sem inoculação. Também foi realizada a técnica de coloração das raízes com fucsina ácida, pelo método de Byrd et al.... |

| Grain yield (GY) and drought tolerance of recombinant chromosome substitution lines (RCSLs) derived from the cross between Hordeum vulgareL.subsp. spontaneum (K. Koch) Thell. and H. vulgare L. subsp. vulgare cv. Harrington, were studied in two contrasting environments, one with water stress (WWS) and the other with no water stress (NWS), during three growing seasons, 2004-2005, 2005-2006 and 2006-2007. In the first season 80 RCSLs were sowed and in the following a selection of 13 RCSLs. An a-lattice design was used in all the experiments. With the data of GY obtained in sites WWS and NWS it was calculated the drought sensitivity index (DSI). During 2004-2005 growing season GY varied greatly among locations, reflecting differences in water availability. The... |

| In situ selection of vineyard peach (Prunus pérsica spp. vulgaris Mill.) genotypes was conducted in 2006 and 2007 in the region of Kfusevac (Central Serbia). Identification, observation and recording of the phenological and pomological properties of the highest-quality genotypes were carried out. Twenty-eight genotypes of the highest quality were selected out of 2093 genotypes, based on biological and pomological properties, and compared to those of cv. Redhaven (control). The onset of flowering varied (April 7-21), being early in two genotypes and late in one genotype, as compared to Redhaven, while 25 genotypes showed an intermediate flowering date, as Redhaven did. Campanula flowers were found in six genotypes, as in Redhaven, and the rosaceous type in... |

| Considering the proximity of sheep farmers to animals that are possibly diseased or releasing fecal oocysts into the environment and the marked pathogenicity in lambs, the aim of this study was to determine the occurrence and to molecularly characterize the infection by Cryptosporidium spp. in lambs in the South Central region of the state of São Paulo, Brazil. A total of 193 fecal samples were collected from sheep of several breeds, males and females, aged up to one year. Polymerase chain reaction (nested-PCR) was used to amplify DNA fragments from the subunit 18S rRNA gene and indicated 15% positivity; sequencing of amplified fragments was possible for 19 samples. Analysis of the obtained sequences showed that the identified species were Cryptosporidium... |

| RESUMO O objetivo desta pesquisa foi avaliar os SNPs rs471462296, rs456245081 e rs438495570 do gene DGAT1 em bovinos Nelore. Foram analisados 109 bovinos. A extração do DNA genômico foi realizada do sangue dos animais, usando-se o kit Ilustra Blood Genomic Prep Mini Spin® (GE Healthcare, UK). A concentração e o grau de pureza do DNA foram determinados por meio de espectrofotômetro (Nanodrop - Thermo Fisher Scientifc, USA). A genotipagem dos SNPs ocorreu mediante o emprego do ensaio Taqman® (Applied Biosystems, USA). Na análise genômica, não foram encontradas alterações nas frequências alélicas e genotípicas (P≥0,05) para os SNPs testados. Dessa forma, a região 5’UTR analisada apresentou-se monomórfica e a variação de SNPs não foi observada, o que limita... |

| CYP2E1 enzyme is related to nonalcoholic steatohepatitis (NASH) due to its ability for reactive oxygen species production, which can be influenced by polymorphisms in the gene. The aim of this study was to investigate hepatic levels, activity, and polymorphisms of the CYP2E1 gene to correlate it with clinical and histological features in 48 female obese NASH patients. Subjects were divided into three groups: (i) normal; (ii) steatosis; and (iii) steatohepatitis. CYP2E1 protein level was assayed in microsomes from liver biopsies, and in vivo chlorzoxazone hydroxylation was determined by HPLC. Genomic DNA was isolated for genotype analysis through PCR. The results showed that liver CYP2E1 content was significantly higher in the steatohepatitis (45%; p=0.024)... |

| The goal of this study was to investigate the molecular characterization of A. macrostachyum genotypes grown in the Western coast of Syria using RAPD and ISSR techniques. PCR amplifications with 20 RAPD primers gave an average of 9.25 selected markers/ primer, with a maximum of 17 (OPG05) and a minimum of four (OPA02). Percentage of polymorphic bands ranged from 40 to 100% according to RAPD primers tested. Among the 185 selected bands, 160 (84.96%) were polymorphic. The amplification with seven ISSR primers generated 88 bands, and 80 (90.91%) were polymorphic. (CA)8RG and (AG)8GTG ISSR primers tested in this study yielded highly informative patterns. RAPD and ISSR fragment sizes ranged from 0.2-3 kb. Based on this study, the use of RAPD and ISSR... |

| Hepatitis C virus (HCV) infection is a serious public health problem, since 80% to 85% of HCV carriers develop a persistent infection that can progress into liver cirrhosis and hepatocarcinoma. Considering that the response of hepatitis C patients to combination therapy with interferon and ribavirin depends on HCV characteristics as well as on host features, we made a retrospective analysis of demographic and anthropometrical data and HCV genotype distribution of chronic hepatitis C patients treated in public and private reference centers in Brazil. The medical records of 4,996 patients were reviewed, 81% from public and 19% from private institutions. Patients' median age was 46 years, and there was a higher prevalence of male (62%) and white patients... |
