1. Análises citogenéticas e expressão da telomerase em sarcoma 180
The cancer is a result of genetic instability. There are two theorical lines which try to explain this pathology origin, the conventional genetic theories and the chromosomal theory of cancer. A lot of neoplastic cell characteristics cant be explained by the conventional theories and they are explained by the chromosomal theory. The telomerase plays an impor

2. Os estudos de Thomas Hunt Morgan sobre determinação de sexo (1900-1914): herança citoplasmática, cromossômica e outras possibilidades
Esta pesquisa, que trata dos estudos de Thomas Hunt Morgan sobre determinação de sexo (de 1900 a 1913), procura elucidar quais foram as principais hipóteses levantadas por Morgan para explicar tal fenômeno; se elas estavam bem fundamentadas; e se houve alguma mudança em seu pensamento durante o período. Além disso, procura saber se as contribuições

3. Desempenho na grafia e na direção grafológica em função da dominância e postura manual em destros e canhotos de famílias de renda baixa e média. ? / . Writing and Graphological Performance as a Function of Handedness and Hand Posture among Right- and Left-Handers from Low and Middle Income Families
There are three distinct theories that seek to explain the origin of the inverted hand posture (IHP) in left-handers. McKeevers genetic model assumes that the trait is sex-linked, tied to maternal transmission via the X-chromosome, which accounts for the higher prevalence of IHP among males. According to the pathological model, the IHP stems from neuropathol

4. Evolutionary aging models: reproductive regimes and the Y chromosome degeneration. / Modelos evolucionários de envelhecimento: regimes reprodutivos e a degeneração do cromossomo Y.
Aging theories can be classified in two types: biochemical theory and evolutionary theory. The biochemical theories explain ageing due to imperfections on the biochemical process responsible for the maintenance of life. The evolutionary theories explain aging without any biochemical mechanisms. They support only adaptive strategies, such as reproduction, her

5. Evolutionary dynamics of the karyotype of the wasp Trypoxylon (Trypargilum) nitidum (Hymenoptera, Sphecidae) from the Rio Doce State Park, Minas Gerais, Brazil
Cytogenetic analysis based on the distribution of C-bands showed two groups of karyotypes in a Trypoxylon nitidum population from the Rio Doce Park, State of Minas Gerais, Brazil. One of these groups, that was identical to a previously described karyotype (n = 15; 2n = 30), had a stable chromosome number and was rich in acrocentric chromosomes, whereas the o

6. A teoria cromossomica da herança : proposta, fundamentação, critica e aceitação
The aim of this thesis is to study the historical context of the establishment of chromosome theory of inheritance in the three ear1ydecades of the XXth century. This work tries to elucidate the main reasons that lead important geneticists of that time, particular1yThomas Hunt Morgan and William Bateson, to delay for a long time the acceptance that Mendelian

7. Generalized Gap Model for Bacterial Artificial Chromosome Clone Fingerprint Mapping and Shotgun Sequencing
We develop an extension to the Lander-Waterman theory for characterizing gaps in bacterial artificial chromosome fingerprint mapping and shotgun sequencing projects. It supports a larger set of descriptive statistics and is applicable to a wider range of project parameters. We show that previous assertions regarding inconsistency of the Lander-Waterman theor
