1. Use of conjugated linoleic acid (trans 10, cis 12) to cultivate bovine embryos: effect on cryoresistance and lipid content
ABSTRACT This study evaluated the effect of the addition of conjugated linoleic acid (CLA) to in vitro culture on viability, lipid content, and cryoresistance of bovine embryos at different in vitro culture times. Cumulus oocyte complexes (N = 974) were maturated in vitro for 22 h. In vitro fecundation ensued for 18 h. Viable zygotes were cultivated in vitro

2. Tissue culture efficiency of wheat species with different genomic formulas
Abstract Ancient wheats are increasingly considered as valuable resources for genes of interest which could be analyzed and introduced into cultivated varieties by genetic engineering technologies. The first stage of biotechnological crop improvement consists of successful in vitro plant regeneration. Twelve wheat germplasms with different genomic formulas (

3. Polyethylene glycol effects on somatic embryogenesis of papaya hybrid UENF/CALIMAN 01 seeds
Among commercial fruits, papaya (Carica papaya L.) is notably one of the most common ones around the world. The aim of the current study was to establish a somatic embryogenesis protocol for the hybrid UENF/CALIMAN 01, elucidating the effects of sucrose and 2,4-dichlorophenoxyacetic acid (2,4-D) on the induction of embryogenic cultures and the effect of poly

4. Trichomonas vaginalis and Tritrichomonas foetus: interaction with fibroblasts and muscle cells - new insights into parasite-mediated host cell cytotoxicity
Trichomonas vaginalis and Tritrichomonas foetus are parasitic, flagellated protists that inhabit the urogenital tract of humans and bovines, respectively. T. vaginalis causes the most prevalent non-viral sexually transmitted disease worldwide and has been associated with an increased risk for human immunodeficiency virus-1 infection in humans. Infections by

5. Efeito do acido giberelico e benzilaminopurina no crescimento in vitro de embrioes do cafeeiro cv.Acaia.
Objetivou-se, com o presente trabalho, avaliar o efeito de diferentes concentracoes de acido giberelico (GA) e citocinina no crescimento in vitro de embrioes do cafeeiro (Coffea arabica L.) cv. Acaia. O experimento foi conduzido no laboratorio de cultura de tecidos da Universidade Federal de Lavras. O delineamento utilizado foi o de blocos ao acaso, em esque

6. Efetividade da UtilizaÃÃo de Incubadoras de CO2 Equipadas com filtro Hepa e Filtro Hepa-Voc para Cultivo de EmbriÃes em Ciclos de FertilizaÃÃo in Vitro / Effectiveness of Using CO2 Incubators equipped with HEPA filters and HEPA-You for Cultivation of Embryos in IVF Cycles
Introduction and objectives. The air quality in sterile environment is an important aspect to cell culture. It is known the culture conditions are essential for in vitro human embryo development; however there is no standardization for incubator filters in in vitro fertilization (IVF) laboratories. Recently, the incubator air quality has been receiving atten

7. Comparision of different cell cultures for replication of infectious laryngotracheitis virus from chickens / Comparação de diferentes cultivos celulares para a replicação do vírus da laringotraqueíte infecciosa das galinhas
A propagação do vírus da laringotraqueíte infecciosa tem sido descrita usando culturas de células primárias derivadas de fígado e rim de embrião de galinha ou ovos embrionados, entretanto, essas culturas necessitam de ovos livres de patógenos específicos (SPF) que tomam tempo e custam caro. Desta maneira, culturas de células de linhagem são mais

8. Retina de aves como sistema circadiano e sua modulação por luz e glutamato / Avian retina as a circadian system and its modulation by light and glutamate
The avian circadian system is composed by the retina, the mammalian homolog region of the supra-chiasmatic nucleus (SNC) and the pineal gland. The retina itself shows many rhythmic physiological events, such as movements of photoreceptor cells, opsin expression, retinaldehyde re-isomerization, melatonin and dopamine production and release. Altogether these r

9. Germinação, emergência da plântula, produtividade e qualidade da fibra de Gossypium hirsutum L. CV. DP 660 sob ação de bioestimulante / Germination, seedling emergence, productivity and fiber quality of Gossypium hirsutum L. cv. DP 660 under action of biostimulants
Cotton is the most important vegetable fiber for man who uses it as a raw material in the production of tissues which has intrinsic qualities unequaled to in other fibers. For this reason, the viability of the seed has been receiving special attention, since its quality is demonstrated in the subsequent cultures, in terms of uniformity, greater performance o

10. Influência da heparina na invasão de células de retina por Toxoplasma gondii
The purpose of this work was to analyze, in an in vitro model, the influence of the heparin on the susceptibility of retinal cells to infection by Toxoplasma gondii. Primary cultures of retinas from chick embryos of 8 and 11 days-old and astrocytes from human optic nerve heads were maintained in coverslips for one week, when were infected with T. gondii tach

11. Criopreservação oocitária: desempenho reprodutivo na fertilização assistida.
The advance of in vitro fertilization (IVF) caused the emergence of a few dilemmas that forcibly led to deep reflections, standing out among these the questioning about the destination of excess embryos originated from this technology. In view of the controversy observed in several cultures as to ethic, moral, religious, political and scientific issues relat

12. Padronização e processo de invasão/inibição de esporozoitos de Eimeria acervulina e E. tenella em celulas primarias de galinha, na presença de lectinas de plantas
The effect of six plant lectins in the invasion of Eimeria acervulina and E. tenella sporozoites using primary chick kidney and embryo cells cultivated in vitro, was examined. Pretreatment of sporozoites with l00 ?g/ml of DViol, DVir, DGr, ConBr, CF, PP and 50 ?g/ml of DViol, DVir, ConBr and PP inhibited significantly the invasion of E. acervulina and E. ten
