Effects of heat stress on development, quality and survival of Bos indicus and Bos taurus embryos produced in vitro

Heat stress is an important cause of poor development and low survival rates in bovine embryos. Experiments were conducted to test the hypothesis that Bos indicus embryos are more resistant to heat stress than are Bos taurus embryos. In experiment 1, Nelore and Jersey embryos from oocyte pick-up-derived oocytes were submitted to heat stress (96 hours post-insemination, 41 °C, 6 hours), developmental ratios were assessed at Day 7 (Day 0 = day of fertilization), and blastocysts were frozen for RNA extraction. Experiment 2 evaluated expression of COX2, CDX2, HSF1, and PLAC8 in previously frozen blastocysts. In experiment 3, Nellore and Angus embryos from oocyte pick-up-derived oocytes were submitted to heat stress (96 hours post-insemination, 41 °C, 12 hours) and transferred to recipients on Day 7. In experiment 4, embryos developed as in experiment 3 were fixed for Terminal deoxynucleotidyl transferase dUTP nick end labeling labeling and total cell counting. In experiment 1, heat stress decreased the percentage of Jersey oocytes that became blastocysts, but had no effect on Nellore embryos (34.6%, 25.0%, 39.5%, and 33.0% for Jersey control, Jersey heat-stressed, Nellore control, and Nellore heat-stressed oocytes, respectively; P < 0.05). In experiment 2, heat stress decreased (P < 0.05) expression of CDX2 and PLAC8, with higher expression of these genes in Nellore embryos than in Jersey embryos. Heat stress also decreased (P < 0.05) expression of COX2 in Jersey embryos, but had no effect on Nellore embryos. Expression of HSF1 was decreased (P < 0.05) by heat stress in both breeds, with a greater effect in Nellore embryos. In experiment 3, heat stress tended (P = 0.1) to decrease the percentage of pregnancies among cows (Day 30 to 35) that received Angus embryos. In experiment 4, heat stress increased (P < 0.05) the percentage of apoptotic blastomeres, but had no breed-specific effects. In addition, Nellore embryos had fewer (P < 0.05) Terminal deoxynucleotidyl transferase dUTP nick end labeling- positive blastomeres than did Angus embryos. We concluded that the detrimental effects of heat stress were dependent upon embryo breed and were more evident in Bos taurus embryos than in Bos indicus embryos. © 2013 Elsevier Inc.

Industrial Development and the Innovation System of the Ethanol Sector in Brazil

The purpose of this paper is to analyze innovations and the innovation system and its dynamics in the ethanol sector in the State of Sao Paulo. More specifically, this paper focuses on the development process in the sector, the public policies taken to promote the sector, and the organizations and key players involved in these policies and their responses to unforeseeable changes in economic, social and technological environments. To this end, this paper takes an historical perspective and reviews data on the cultivation of sugar cane, the production of ethanol, and on sugar cane yields as indicators of the innovations achieved in the sector. The geographical distribution of these indicators is also examined. Next, several cases in Piracicaba and Campinas in the State of Sao Paulo are presented; these give us a more concrete idea of the processes involved in innovation and technology transfer. Based on these observations, the ethanol cluster and the innovation system of the State of Sao Paulo are discussed from the viewpoint of the flowchart approach to industrial cluster policy.

Serum Starvation and Full Confluency for Cell Cycle Synchronization of Domestic Cat (Felis catus) Foetal Fibroblasts

Nuclear transfer of domestic cat can be used as a tool to develop reproductive biotechnologies in wild felids. The importance of cell cycle phase during the nuclear transfer has been a matter of debate since the first mammalian clone was produced. The cell cycle phase of donor cells interferes on maintenance of correct ploidy and genetic reprogramming of the reconstructed embryo. The use of G0/G1 arrested donor cells has been shown to improve nuclear transfer efficiency. The present study was conducted to test the hypothesis that domestic cat foetal fibroblasts cultured up to the fifth passage and submitted to full confluency provide a higher percentage of cells at G0/G1 stage than fibroblasts cultured in serum starved media. Results demonstrated that serum starvation increased (p < 0.05) the percentage of G0/G1 fibroblasts when compared with control. Moreover, the combined protocol using confluency and serum starvation was more efficient (p < 0.05) synchronizing cells at G0/G1 stage than serum starvation or confluency alone for the first 3 days of treatment. In conclusion, serum starvation and full confluency act in a synergistic manner to improve domestic cat foetal fibroblast cell cycle synchronization at the G0/G1 stage.

Siirtohinnoittelun kehitys ja tulevaisuus vuosien 1994–2014 ammattilehtikirjoitusten perusteella

Pro gradu-tutkimuksen tarkoituksena on selvittää, miten siirtohinnoittelun kehitys näkyy ammattikirjoituksissa 20 vuoden aikana sekä mihin suuntaan siirtohinnoittelu on kehittymässä tulevaisuudessa. Mitkä ovat siirtohinnoittelun riskit ja edut tutkimusaineiston perusteella ja minkälaisista näkökulmista siirtohinnoittelusta on 20 vuoden aikana kirjoitettu. Artikkeleista pyritään löytämään, minkälaisia eroja on suomalaisen ja kansainvälisen kirjoittelun väliltä. Tämä on laadullinen tutkimus, jossa käytetään tutkimusmenetelmänä sisällönanalyysia. Tutkimuksessa on sisällönanalyysin mukaisesti luokittelua, teemoittelua sekä vertailua. Tutkimusaineisto koostuu kolmesta lehdestä Verotus, Tilintarkastus-lehti, nykyään Balanssi ja The Accounting Review. Lehdistä on kerätty siirtohinnoittelua käsittelevät artikkelit 20 vuoden ajalta. Tutkimustulosten perusteella näkyy siirtohinnoittelun kehitys sekä kuinka aiheesta on tullut entistä keskeisempi. Siirtohinnoittelu on nyt merkittävässä roolissa kansainvälisessä verotuksessa. Haasteena nähdään markkinaehtoisen hinnan asettaminen oikeaan arvoon. Tärkeänä luokkana nousi siirtohinnoittelun kehittäminen. Myös valtioiden uhka siitä, että siirtohinnoittelun kautta verovaroja siirtyy toisiin valtioihin, oli yksi esiin noussut teema. Johtopäätöksenä voidaan todeta, että siirtohinnoittelu on problemaattinen verotuksen aihe, koska selkeää suoraa siirtohintaa ei aina pystytä antamaan tuotteelle, palvelulle tai rahoitukselle, vaan hinta on veteen piirretty viiva. Siirtohinnoittelua pidetään uhkana valtioiden veropohjan rappeutumiselle, jos sen avulla siirretään varoja alemman verotuksen valtioihin. Konsernit toimivat entistä laajemmin eri valtioissa, joten niiden tavoitteena on suunnitella eri konsernin osien tulosta. Tulevaisuudessa on paljon kehityskohtia ja tarpeita siirtohinnoittelun alueella. Kehitykseen vaikuttavat valtioiden yhteisöveropoliittiset päätökset sekä valtioiden omat lainsäädännöt sekä valtioiden sitoutuminen OECD:n säännöksiin, joiden avulla pyritään yhtenäisiin toimintamalleihin. Jatkossa tutkimusta voisi laajentaa kansainvälisemmäksi sekä vielä syvemmin voisi miettiä myös kehityksen suuntia ja niiden vaikutuksia.

Le développement positif des jeunes en contexte sportif parascolaire : évaluation du programme d’intervention psychosociale Bien dans mes Baskets

L’objectif général de cette thèse était d’explorer le développement personnel de jeunes à risque de délinquance et de décrochage scolaire à travers leur participation à un programme d’intervention psychosociale nommé « Bien dans mes Baskets » (BdmB). Ce programme utilise le basketball parascolaire comme outil d’intervention et il a comme particularité qu’une bonne partie de ses entraineurs-intervenants détiennent une formation professionnelle en travail social ou domaines connexes. Cette thèse présente les résultats de trois études faisant partie d’un projet de recherche plus vaste portant sur l’évaluation du programme BdmB. Une première étude a exploré le processus de transfert, à d’autres domaines d’activités, des habiletés de vie ciblées par le programme BdmB. Des entretiens semi-directifs ont été réalisés auprès de 14 anciens participants et sept anciennes participantes du programme. Nos résultats suggèrent que trois principaux facteurs semblent avoir joué un rôle dans le processus de transfert des habiletés de vie développées au sein de BdmB, soit la présence de contextes favorisant l’apprentissage expérientiel, la valeur relative accordée aux différents domaines d’activités et la trajectoire de vie. Il ressort également de nos données qu’au-delà du processus de transfert sur une base individuelle, il est possible qu’un transfert puisse s’opérer dans la communauté. L’objectif de la deuxième étude était d’explorer comment et dans quelle mesure les expériences au sein de BdmB ont pu servir de levier au processus d’empowerment. Des entretiens semi-directifs ont été réalisés auprès de sept anciennes participantes de BdmB. Nos résultats suggèrent que la pratique sportive, combinée à une intervention psychosociale, peut contribuer au développement d’un plus grand contrôle sur sa vie. Cette amélioration serait la résultante cumulative de divers apprentissages, dont le développement et le transfert d’habiletés de vie et la capacité à résister aux influences externes négatives présentes dans leurs milieux de vie respectifs, ainsi que l’impact positif des expériences vécues au sein de BdmB sur la persévérance scolaire et les aspirations professionnelles. Une troisième étude avait pour objectif d’évaluer l’impact du programme BdmB sur le sentiment d’appartenance à l’école et la perception de soutien social. Un devis quasi expérimental a été utilisé pour évaluer l’impact du programme auprès des athlètes-étudiants(es) actuels. Le groupe d’intervention était composé des athlètes-étudiants de BdmB et les groupes de comparaison étaient constitués des étudiants de la même école ne participant pas au programme et pratiquant ou non un autre sport. Les individus ont été sondés à deux reprises à l’aide d’un questionnaire auto administré sur une période de deux années scolaires. Les résultats de l’étude indiquent que le groupe BdmB a développé un meilleur sentiment d’appartenance et a perçu un meilleur soutien social par rapport aux groupes de comparaison.

Múltiples derechos, la misma desprotección: la eficacia simbólica de los derechos de las mujeres indígenas desplazadas en Colombia

Este artículo indaga por las dificultades en la protección de los derechos de las mujeres indígenas desplazadas, en el contexto de la pluralidad jurídica de que son sujetas y de la eficacia simbólica que comportan estos múltiples ordenamientos para ellas. Con base enla observación participante realizada por el autor, se sostiene que las relaciones entre la pluralidad interna y externa de los ordenamientos jurídicos, así como la eficacia simbólica, privilegian los intereses de los hombres y el Estado, y generan la desprotección de las mujeres indígenas desplazadas a través de fenómenos específicos. En la primera parte, se examinanlas dificultades internas y externas de los ordenamientos nacional e internacional y su eficacia simbólica, las cuales no permiten desarrollar los derechos de las mujeres indígenas desplazadasde forma específica y diferenciada. En la segunda parte, se analizan los argumentos locales que, desde el punto de vista de las mujeres indígenas, dificultan las reclamaciones de sus derechos. Finalmente, se observan tres fenómenos específicos de desprotección de las mujeres indígenas desplazadas.

A síndrome do hiperestímulo ovariano não influencia os resultados clínicos após ciclos de descongelamento de embriões provenientes de ciclos de ICSI

Objective: The objective of this study was evaluate if the embryos cryopreservation from OHSS patients Intracytoplasmic Sperm Injection (ICSI) cycles could be influence the clinical outcomes when compared to patients who receive oocytes from donors but the endometrium was not prepared and the embryos were cryopreserved. Methods: Fifty eight couples submitted to ICSI cycles in which 26 with OHSS clinical manifestation (OHSS group) and 32 couples who have received oocytes from donors (control group). The embryos were frozen on day+2 or +3of development. All patients included in this study had embryos crypreserved before the transfer, and in the thawing cycle, only the endometrium preparation was performed. The embryo survival, implantation, pregnancy and miscarriage rates were evaluated in the embryo thawing cycle. Results: There was no difference among the groups in relation to fertilization rate (OHSS: 71.89% ± 15.45, Control: 79.75% ± 21.68, p= 0.234), survival embryos rate (OHSS: 68.85 ± 21.10, Control: 59.53 ± 36.79, p= 0.233), high quality embryos rate (OHSS: 25.20 ± 23.90, Control: 27.40 ± 30.30, p= 0.760), implantation rate (OHSS: 17.9 ± 26.9, Control: 12.5 ± 23.7, p= 0.435), pregnancy rate (OHSS: 38.50, Control: 28.60, p= 0.441) and miscarriage rate (OHSS: 40.00, Control: 25.00, p= 0.332). Conclusion: Our findings suggest that clinical outcomes in freeze and thawing cycles were not affected by the presence of ovarian hyperstimulation syndrome clinical manifestation after controlled ovarian stimulation.

HDAC inhibition decreases XIST expression on female IVP bovine blastocysts

During initial development, both X chromosomes are active in females, and one of them must be silenced at the appropriate time in order to dosage compensate their gene expression levels to male counterparts. Silencing involves epigenetic mechanisms, including histone deacetylation. Major X chromosome inactivation (XCI) in bovine occurs between hatching and implantation, although in vitro culture conditions might disrupt the silencing process, increasing or decreasing X-linked gene expression. In this study, we aimed to address the roles of histone deacetylase inhibition by trichostatin A (TSA) on female preimplantation development.We tested the hypothesis that by enhancing histone acetylation, TSA would increase the percentage of embryos achieving 16-cell stage, reducing percentage of embryos blocked at 8-cell stage, and interfere with XCI in IVF embryos. We noticed that after TSA treatment, acetylation levels in individual blastomeres of 8-16 cell embryos were increased twofold on treated embryos, and the samewas detected for blastocysts. Changes among blastomere levels within the same embryo were diminished on TSA group, as low-acetylated blastomeres were no longer detected. The percentage of embryos that reached the 5th cleavage cycle 118 h after IVF, analyzed by Hoechst staining, remained unaltered after TSA treatment. Then, we assessed XIST and G6PD expression in individual female bovine blastocysts by quantitative real-time PCR. Even though G6PD expression remained unaltered after TSA exposure, XIST expression was eightfold decreased, and we also detected a major decrease in the percentage of blastocysts expressing detectable XIST levels after TSA treatment. Based on these results, we conclude that HDAC is involved on XCI process in bovine embryos, and its inhibition might delay X chromosome silencing and attenuate aberrant XIST expression described for IVF embryos. © 2013 Society for Reproduction and Fertility.

Integration practices for the technological innovation of products: Case studies at two large technological companies

Studies on innovation and technology management have emphasized the importance of integration between the research and development (R&D) department and others involved with the product development process (PDP) as a relevant practice for the good performance of technological innovation of product activities. This study addresses the topic of transfers of technologies to new product projects and also integration practices between the R&D department and others involved with the PDP. A qualitative study was conducted that was operationalized through two case studies at large high-tech companies: One is Brazilian and the other is a multinational subsidiary in Brazil. Among its main result, this paper represents and analyzes management practices that are favorable to integration in product development projects that demand development and transfer of technologies, such as: participation of R&D personnel in market activities, the adoption of virtual interaction mechanisms, and the application of methods such as technology roadmaps. © Universidad Alberto Hurtado, Facultad de Economía y Negocios.
