1. Aspectos genéticos do envelhecimento e doenças associadas: uma complexa rede de interações entre genes e ambiente
Resumo O envelhecimento é um processo dinâmico, no qual ocorrem modificações do nível molecular ao morfo-fisiológico, logo após a maturidade, que induzem ao declínio orgânico, aumentando a susceptibilidade e vulnerabilidade a doenças e à morte. A genética do envelhecimento dedica-se ao estudo da contribuição hereditária da espécie e sua inter

2. Risk of genetic vulnerability and aspects of the reproductive biology of Psychotria ipecacuanha (Rubiaceae), a threatened medicinal plant species of Brazilian forests
ABSTRACT Psychotria ipecacuanha, commonly known as Ipeca, is a medicinal plant of pharmacological and economic value. The species is distylous; it has populations with two floral morphs, one with long and one with short styles. Apart from the presence of two floral morphs in a balanced ratio (1:1), reciprocal herkogamy of the reproductive organs between alte

3. Genetic diversity reduction in improved durum wheat cultivars of Morocco as revealed by microsatellite markers
ABSTRACT It has been argued that genetic diversity in crop varieties has been on the decline in recent times due to plant breeding. This can have serious consequences for both the genetic vulnerability of crops and their plasticity when responding to changes in production environments. It is, therefore, vital for plant breeding programs to maintain sufficien

4. A review on the evidence of transgenerational transmission of posttraumatic stress disorder vulnerability
Objective: To understand the risks of posttraumatic stress disorder (PTSD) development in the next generation of PTSD patients, we conducted a review on the biological, but not genetic, evidence of transgenerational transmission of PTSD vulnerability. Methods: Pertinent articles published from 1985 to September 2011 were searched using online academic searc

5. Use of psychoactive substances by adolescents: current panorama
Adolescence is a period of vulnerability to substance use disorders (SUDs). Epidemiological studies indicate that about 23% of Brazilian adolescents use drugs, with alcohol being the most widely consumed substance. The etiology of SUDs is complex, influenced by an interaction of genetic risk, individual development, environmental factors, context of use, and

6. Condrogênese a partir de células-tronco do líquido amniótico humano estimulado com TRF-ß3 em micromass / Chondrogenesis differentiation of mesenchymal stem cells from human amniotic fluid with TGF-beta3 in micromass culture system
Introduction: The use of mesenchymal stem cells (MSC) for reconstruction of articular cartilage, leads to a promising therapeutic alternative, due to the tissue vulnerability to injuries and irreversible degenerative process. The aim of this study was to investigate the chondrogenic potential of MSC from human amniotic fluid in Micromass system (high-density

7. Principio da vulnerabilidade : fundamento da responsabilidade civil objetiva por violação ao direito à intimidade genética nas relações de consumo e de emprego no Brasil contemporâneo.
This dissertation was elaborated by bibliographic research and deals with pertaining aspects to the kind of civil accountability by violation to the right of genetic privacy in expenditure and work relationship. Through extensive interpretation of the right to privacy, fixed on article 5th, item X, of the Federal Constitution of Brazil of 1988, corroborated

8. Limites impostos pela bioética e pelo direito brasileiro à manipulação genética na reprodução humana assistida.
This paper addresses the concern had been raised around the handling of the human genome especially in regard to the practices of genetic engineering in assisted reproduction and resulting need for protection of human genetic heritage for future generations. Accordingly we analyze the evolution of scientific knowledge to the genetic modification of biotechno

9. Desenvolvimento de cultivares do gênero Brachiaria (trin.) Griseb no Brasil.
In Brazil, cultivated pastures cover more than 100 million hectares and Brachiaria species cover more than 45 million hectares. B. brizantha cv. Marandu and B. decumbens cv. Basilisk are the primary cultivars. The large areas occupied by the same cultivars pose a vulnerability to the beef cattle activity, and make clear how necessary is to increase the genet

10. Base genetica das cultivares de arroz (Oryza sativa L.) irrigado do Brasil.
Foram analisadas as genealogias de 42 cultivares de arroz irrigado recomendadas para cultivo no Brasil, de 1980 a 1992. Verificou-se que apenas dez ancestrais contribuem com 68% do conjunto genico das variedades brasileiras de arroz irrigado. Considerando as cultivares mais plantadas nos principais estados produtores de arroz irrigado, constata-se que sete a

11. Contribuição genética dos ancestrais da soja às cultivares brasileiras / Genetic contribution of soybean ancestors to Brazilian soybean cultivars
A soja é uma oleaginosa com grande destaque na economia mundial. O Brasil é o segundo maior produtor de soja, após os EUA, ressaltando a importância desta cultura para o país. Para que haja progresso genético nesta cultura, é necessário que haja diversidade genética e uma das maneiras de se estimar a diversidade genética de um grupo é através do

12. Genetic structure of Melipona capixaba Moure e Camargo, 1994 (Hymenoptera: Apidae) / Estrutura genética de Melipona capixaba Moure e Camargo, 1994 (Hymenoptera: Apidae)
The bee specie Melipona capixaba, popularly known as uruçu negra (black uruçu), is endemic in the mountainous region of the State of Espirito Santo, Brazil, and it is included since 2003 in the list of threatened species of IBAMA, the only eusocial insect in this list. In order to characterize the genetic diversity and populational structure of this bee, s
