13. Functional integrity of Colossoma macropomum (Cuvier, 1816) sperm cryopreserved with enriched extender solutions
As soluções crioprotetoras são utilizadas para proteger os espermatozoides das alterações causadas por baixas temperaturas durante o processo de criopreservação. Avaliamos a qualidade do sêmen de Colossoma macropomum após o congelamento, utilizando dimetilsulfóxido (DMSO) como crioprotetor, combinado com duas soluções diluidoras (T1 - Solução 1

15. Seasonal variation in sperm characteristics of boars in southern Uruguay
The objective of this study was to evaluate the effects of season, natural photoperiod, and room temperature at the housing facility on boar semen characteristics in Uruguay (34º66'S; 56º29'W). For this purpose, 117 ejaculates, obtained from eight adult males collected through 12 consecutive months, were assessed for sperm viability, DNA integrity, abnorma

16. Novel insights into the genetic and epigenetic paternal contribution to the human embryo
The integrity of the sperm genome and epigenome are critical for normal embryonic development. The advent of assisted reproductive technology has led to an increased understanding of the role of sperm in fertilization and embryogenesis. During fertilization, the sperm transmits not only nuclear DNA to the oocyte but also activation factor, centrosomes, and a

18. Buccal cells DNA extraction to obtain high quality human genomic DNA suitable for polymorphism genotyping by PCR-RFLP and Real-Time PCR
OBJECTIVE: The aim of this study was to evaluate, by PCR-RFLP and real-time PCR, the yield and quality of genomic DNA collected from buccal cells by mouthwash after different storage times at room temperature. MATERIAL AND METHODS: A group of volunteers was recruited to collect buccal cells using a mouthwash solution. The collected solution was divided into

19. Avaliação do swim-up e do gradiente descontinuo de densidade na pré-seleção do sexo de espermatozoides na produção de embriões bovinos
The purpose of this work was to associate the modified swim-up method with centrifugation in density gradient for the separation of X-bearing spermatozoa. Sperm viability and integrity were evaluated through the Trypan Blue/Giemsa staining method. Quality control of centrifuged spermatozoa was performed in in vitro produced embryos. The results were validate

20. AvaliaÃÃo do potencial antitumoral e antiangiogÃnico de novos anÃlogos ftalimÃdicos da talidomida / EVALUATION OF THE ANTITUMOR AND ANTIANGIOGENIC POTENTIAL OF NEW FTHALIMIDES THALIDOMIDE ANALOGUES
The thalidomide was previously used to relieve gastric discomforts during pregnancy, and currently it is used for cancer treatment and inflammatory illnesses. Various phthalimides analogues of thalidomide have been researched for its antiangiogenic and immunemodulatory activity. In previous studies, these analogues showed absence of immunesuppressor activity

21. Incorporation of strontium up to 5 Mol. (%) to hydroxyapatite did not affect its cytocompatibility
The aim of this work was to produce hydroxyapatite (HA) granules containing 0, 0.5, 1 and 5 mol. (%) of strontium (Sr), evaluate the physico-chemical properties and also the cytotoxicity by three different parameters of cell viability (ISO 10993-5, 10993-12). The physico-chemical characterization was carried out by using X-ray diffraction (XRD), Fourier-tran

22. Método de TÚNEL: uma ferramenta alternativa para avaliar a integridade do DNA de espermatozóides bovinos.
ABSTRACT: The success of the assisted reproductive techniques (ART) in both humans and domestic animals depends of the semen quality. Since there is no test that alone can predict sperm fertility, as more sperm parameters are analyzed during evaluation, more acurated will the result. The evaluation of the DNA integrity during the exam of bovine fresh and fro

23. Associação entre haplótipos de metaloproteinase-9 de matriz extracelular (MMP-9) e obesidade infantil : efeitos sobre a concentração plasmática de MMP-9 / Association between haplotypes of matrix metalloproteinase-9 extracellular matrix (MMP-9) and childhood obesity : effects on plasma concentration of MMP-9
The childhood obesity is important risk factor for cardiovascular diseases, in particular, atherosclerose. This condition is characterized by the accumulation of lipids and fibrous elements in the large arteries in which inflammatory mechanisms and vascular remodeling are involved. In this context, matrix metalloproteinase 9 (MMP-9) - endopeptidade capable o

24. Helicobacter pylori e polimorfismos em enzimas de reparo de DNA e de sÃntese de Ãxido nÃtrico no cÃncer gÃstrico / Helicobacter pylori infection and polymorphisms in DNA repair enzymes and iNOS in gastric cancer
Gastric cancer is the most deadly malignant neoplasia worldwide, with high incidence in Brazil and Helicobacter pylori infection is a well-established risk factor. Depending on the presence of virulence genes such as cagA, cagE, vacA and virB11, H. pylori can cause differentiated inflammatory responses, with large amounts of nitric oxide (NO) generated prima
