1. Epidemiologia e caracterização molecular do vírus da Influenza em quatro espécies de pinguins na Região Antártica. / Epidemiology and molecular characterization of the influenza virus in four penguin species of the antartic region.
Epidemics and pandemics of influenza usually refer to infections in human beings. The influenza virus is not, however, restricted to humans and can cause infirmity and death in other species including horses, swine, marine mammals, birds, and others. Ecological studies of viral infections have led to the hypothesis that the influenza viruses that attack mamm

2. Identificação de marcadores de pluripotência em células-tronco embrionárias e embriões suínos / Identification of pluripotency markers in swine embryonic stem cells and embryos
Células-tronco embrionárias (CTE) são importantes para estudos de desenvolvimento embrionário, diferenciação e manipulação genética. Além disso, essas células podem ser utilizadas na terapia celular e organogênese in vitro. Na pesquisa sobre terapia celular a partir de CTE oriundas de embriões humanos, considerações éticas, morais e religiosa

3. Presence of active Caspase-3 and DNA damage and repair proteins in parthenogenetically activated swines embryos of high and low developmental capacity / Presença da Caspase-3 ativa e das proteínas de reparo de lesões do DNA em embriões suínos ativados partenogeneticamente com alta ou baixa capacidade de desenvolvimento
Apoptose é uma forma de morte celular extremamente conservada que tem papel primordial no desenvolvimento animal e na homeostasia celular, agindo como mecanismo de controle de qualidade com a função de remover células danificadas, em excesso ou não-funcionais. Este processo tem papel importante no desenvolvimento embrionário pré-implantacional, pois a

4. ROLE OF GnRH DURING EARLY EMBRYONIC DEVELOPMENT AND DEVELOPMENT OF SWINE EMBRYOS FOLLOWING VITRIFICATION BY MICRODROPLET METHOD / AÇÃO REGULATÓRIA DO GnRH NO DESENVOLVIMENTO EMBRIONÁRIO PRECOCE E VITRIFICAÇÃO DE EMBRIÕES SUÍNOS PELO MÉTODO DE MICROGOTA
O objetivo do presente estudo foi investigar a importância do GnRH no desenvolvimento embrionário precoce em camundongos. GnRH-I, GnRH-II e os GnRH agonistas: Des-Gly, Des-Trp e histrelina não incrementaram o desenvolvimento embrionário. Entretanto, o tratamento com SB-75, um antagonista específico do GnRH, bloqueou o desenvolvimento embrionário no est

5. Anatomohistopatological study of ovarian cystic degeneration in gilts submitted to a association of gonadotrophins and flushing feed / Estudo anatomohistopatológico da degeneração cística ovariana em fêmeas suínas submetidas a associação de gonadotrofinas exógenas e flushing alimentar
The experiment carried out in LPS (Swine Research Laboratory) and LOV (Oncology Veterinary Laboratory) of Veterinary Medicine and Animal Science Faculty of São Paulo University (FMVZ-USP), verified the cystic degeneration and their histopatological traits in gilts, treated witht the combination of gonadotophins and flushing. 72 pre-pubertal gilts of PenArLa

6. Emprego de diferentes doses de LH suíno na indução e sincronização da puberdade em marrãs / Use of different doses of Swine LH in puberty induction and synchronization in gilts
The research carried out at the Swine Research Laboratory, of FMVZ - USP, Campus of Pirassununga, studied the effects of the use of different hormonal doses on the induction and synchronization of puberty in gilts. Sixty-seven Camborough 22 Agroceres PIC® females with 140 days of age and 86kg of body weight were submitted to the following treatments: contro

7. Combined effects of gonadotropin and flushing in pubertal gilts / Estudo dos efeitos combinados de gonadotrofinas e flushing em marrãs à puberdade
The objective of this study, held at the Swine Research Laboratory of the School of Veterinary Medicine and Zootechnology of the Univ. of São Paulo in Pirassununga, São Paulo, was to verify the combined effects of exogenic gonadotropin (eCG and LH) and flushing on the duration and dispersion of the manifestation of initial and second estruses, cyclicity of

8. Hemagglutinin polymorphism as the basis for low- and high-yield phenotypes of swine influenza virus.
Single amino acid substitutions at the rim of the receptor binding site of the hemagglutinin molecule of swine influenza virus markedly influence the replicative capacity of the virus in chicken embryos, Madin-Darby canine kidney cells (MDCK), and swine as well as its antigenic phenotype. Mutants of low-yield (L) phenotype replicate poorly in chicken embryos

9. Genetic dimorphism in influenza viruses: Characterization of stably associated hemagglutinin mutants differing in antigenicity and biological properties
Influenza virus recombinant X-53 produced for use in the 1976 National Immunization Program for swine influenza was found to comprise two types of virions differing in their antigenic, replicative, and plaque-forming characteristics. One type, characteristic of X-53 and designated “L,” was relatively low-yielding in chicken embryos, produced small clear

10. Hemagglutinin mutants of swine influenza virus differing in replication characteristics in their natural host.
In two mutant clones (L and H) of A/NJ/11/76 (Hsw 1N1) influenza viruses which differ slightly antigenically and markedly in replication characteristics in chicken embryos and Madin Darby canine kidney cells, these pleiotropic differences are mediated by mutation in the hemagglutinin gene (E. D. Kilbourne, Proc. Natl. Acad. Sci. U.S.A. 75:6258--6262, 1978).

11. Monoclonal antibodies to the hemagglutinin Sa antigenic site of a/pr/8/34 influenza virus distinguish biologic mutants of swine influenza virus.
The dimorphic L and H hemagglutinin mutants of A/NJ/11/76(H1N1) (swine) influenza virus differ pleiotropically in their replication and virulence characteristics and in their antigenicity. L mutants replicate less well in chicken embryos and Madin-Darby canine kidney cells and are more infective for swine than are H mutants. L and H mutants are not antigenic

12. Significant Improvement in Cloning Efficiency of an Inbred Miniature Pig by Histone Deacetylase Inhibitor Treatment after Somatic Cell Nuclear Transfer1
The National Institutes of Health (NIH) miniature pig was developed specifically for xenotransplantation and has been extensively used as a large-animal model in many other biomedical experiments. However, the cloning efficiency of this pig is very low (<0.2%), and this has been an obstacle to the promising application of these inbred swine genetics for biom
