25. Tomato progenies selection in Rondônia, Brazil
RESUMO O objetivo deste trabalho foi selecionar progênies endogâmicas de tomate, a partir da cultivar Yoshimatsu e realizar teste de progênies no estado de Rondônia, seguindo o delineamento de blocos ao acaso com quatro repetições e oito plantas por parcela, num espaçamento de 1x0,5 m, conduzidas com uma haste. Mediante analise dos resultados verifico

26. Environmental effects on performance of progeny from different Nellore sires in Brazilian semiarid region
RESUMO O objetivo deste trabalho foi avaliar a influência dos fatores ambientais sobre o desempenho das progénies de diferentes touros da raça Nelore no semiárido brasileiro. Informações de 741 animais foram coletadas de uma fazenda comercial localizada no municipio de Varzelândia-MG. Os animais eram filhos de 27 touros da raça Nelore e eram categori

27. Avances en la propagación del aguacate
Abstract Being the avocado a highly cross-pollinated and heterozygous species, its multiplication from seeds produces a highly variable progeny in relation to the morphological and biological characteristics of the parents. Therefore, the adoption of more efficient propagation methods for obtaining higher quality seedlings in terms of production and disease

28. Evaluation of Dietary Supplement Intake (Yeast Tablets) on Pregnant Albino Rats and Their Fetuses (Implications of Yeast Tablets on Rats & Fetuses)
ABSTRACT Histopathological studies in placenta, liver, kidney, apoptotic DNA damage and p53 mutation estimation of pregnant rats and their offspring exposed to dietary supplement yeast tablets, were carried out. Pregnant female albino rats were orally administrated yeast tablets at concentration 41.1 mg/kg during gestation period. Hematoxylin and eosin stain

29. Human papillomavirus and genome instability: from productive infection to cancer
Infection with high oncogenic risk human papillomavirus types is the etiological factor of cervical cancer and a major cause of other epithelial malignancies, including vulvar, vaginal, anal, penile and head and neck carcinomas. These agents affect epithelial homeostasis through the expression of specific proteins that deregulate important cellular signaling

30. Estimation of genetic parameters and selection for rooting capacity in peach
Abstract One of the most important criteria in the improvement of rootstocks is easiness of propagation. The objective of the present study was to verify the existence of genetic variability and the possibility of gains with selection in the rooting capacity among peach genotypes. Seventy-seven genotypes of peach belonging to five F3 families were evaluated.

31. Impact of embryo transfer phenotypic records on large-scale beef cattle genetic evaluations
ABSTRACT We aimed to evaluate the impact of using embryo transfer (ET) information on weaning weight estimated breeding values (EBV) and its accuracy. Data from Hereford and Braford cattle, raised under extensive conditions in Southern Brazil, were used. A model that included ET information in addition to maternal (genetic and permanent environmental) effect

32. Assessing the association between hypoxia during craniofacial development and oral clefts
Abstract Objectives To evaluate the association between hypoxia during embryo development and oral clefts in an animal model, and to evaluate the association between polymorphisms in the HIF-1A gene with oral clefts in human families. Material and Methods The study with the animal model used zebrafish embryos at 8 hours post-fertilization submitted to 30%

33. Genetic diversity assessment of the Mexican Simmental population through pedigree analysis
ABSTRACT The purpose of this study was to examine the genetic variability of the Mexican Simmental. Inbreeding was calculated by year for animals born from 1985 to 2014. Proportion of ancestors known, average equivalent complete generations, generation interval, and effective size, as well as the effective numbers of founders, ancestors, and founder genomes

34. Neonatal tobacco smoke reduces thermogenesis capacity in brown adipose tissue in adult rats
Maternal smoking is a risk factor for progeny obesity. We have previously shown, in a rat model of neonatal tobacco smoke exposure, a mild increase in food intake and a considerable increase in visceral adiposity in the adult offspring. Males also had secondary hyperthyroidism, while females had only higher T4. Since brown adipose tissue (BAT) hypofunction i

35. Effect of alcoholic beverages on progeny and reproduction of mice
ABSTRACT Alcohol is the most commonly consumed substance in the world. The objective of this study was to evaluate the influence of alcoholic beverages on male reproduction and possible alterations in their offspring. The mice were divided into 4 groups: beer, wine, cachaça (a type of sugarcane rum), with ethanol concentrations of 1.9 g/kg, and control grou

36. Genetic Resistance to Rust of Eucalyptus urophylla Progenies
ABSTRACT This study assessed the genetic variability in open-pollinated progenies of Eucalyptus urophylla for resistance to rust (Puccinia psidii). The progeny trial was conducted on a statistical randomized block design with 20 progenies, five plants per plot, and nine replications. Analysis of variance showed high genetic variability for the studied trait,
