1. Modelagem computacional de estruturas anatômicas em 3D e simulação de suas imagens radiográficas / Computational 3D modelling of anatomic structures and simulation of its radiography images
The conventional methods of quality control applied to radio diagnosis are the best way to have assured good quality of the produced images. Due the amount of variables to consider, the study of particular issues of the process of formation of radiological images requires complementary computational tools. However, the computational voxel based phantoms are

2. Morphologycal analysis of the transition site of the primitive intestine to the yolk sac in bovine embryos and fetal (24 to 50 days gestation) / Análise morfológica da área de transição do intestino primitivo para o saco vitelino em embriões e fetos bovinos (24 a 50 dias de gestação)
O saco vitelino é a principal fonte de nutrição do embrião durante o período em que a placenta verdadeira ainda não está completamente formada. É responsável pela hematopoiese, pois dele se desenvolvem os primórdios das células sanguíneas, bem como parte do sistema circulatório primitivo do embrião. Tivemos como objetivo caracterizar a área tr

3. Estudo do desenvolvimento do aparelho digestório de embriões bovinos (Bos indicus e Bos taurus) durante o período gestacional compreendido entre 10 e 60 dias / Study of development of digestive tract of bovine embryos (Bos indicus and Bos taurus) during gestational period between 10 and 60 days
The embryonary period extends itself from 15th to 45th day of gestation in cows, when a fast growing and differentiation occurs, during which the main organs, tissues and systems are established and the main characteristics are recognized. In bovines, most of the organs and parts of body are formed between 2th and 6th week of gestation. During this period, t

4. Isolation of a cDNA corresponding to a developmentally regulated transcript in rat intestine.
We report the isolation of a cDNA clone corresponding to a transcript that is accumulated differentially in rat intestine during development. Clone OCI-5 was selected from the rat intestinal cell line IEC-18, which represents primitive intestinal epithelial crypt cells. Expression was high in rat fetal intestine between 15 and 19 days of development and ther

5. Gastrointestinal Epithelium Is an Early Extrathymic Site for Increased Prevalence of CD34+ Progenitor Cells in Contrast to the Thymus during Primary Simian Immunodeficiency Virus Infection
The objective of this study was to determine the effects of primary simian immunodeficiency virus (SIV) infection on the prevalence and phenotype of progenitor cells present in the gastrointestinal epithelia of SIV-infected rhesus macaques, a primate model for human immunodeficiency virus pathogenesis. The gastrointestinal epithelium was residence to progeni

6. Stage- and tissue-specific expression of two homeo box genes in sea urchin embryos and adults.
We report the isolation of two different homeo box genes, HB3 and HB4, from the Hawaiian sea urchin Tripneustes gratilla. DNA sequencing revealed a definitive Antennapedia (Antp) class homeo box in each gene. Southern transfer hybridizations showed the genes to be single-copy. A 5.7-kb transcript of the HB3 gene was found in ovary, testis, small intestine an

7. Mechanisms of Giardia lamblia differentiation into cysts.
Microbiologists have long been intrigued by the ability of parasitic organisms to adapt to changes in the environment. Since most parasites occupy several niches during their journey between vectors and hosts, they have developed adaptive responses which allow them to survive under adverse conditions. Therefore, the life cycles of protozoan and helminthic pa
