13. Utilization of equine chorionic gonadotropin and/or carp pituitary extract in the induction of the reproduction of curimba (Prochilodus lineatus) / UtilizaÃÃo de gonadotropina coriÃnica eqÃina e/ou extrato bruto de hipÃfise de carpa na induÃÃo da reproduÃÃo de curimba (Prochilodus lineatus).
O estudo avaliou os efeitos da utilizaÃÃo da gonadotropina coriÃnica eqÃÃna (eCG) e do extrato bruto de hipÃfise de carpa (EBHC) combinados ou nÃo, na induÃÃo da reproduÃÃo de machos e fÃmeas de curimba (Prochilodus lineatus). Foram testados 4 tratamentos hormonais diferentes com duas doses intervaladas em 12 horas (A: EBHC 0,5 mg/kg e EBHC 5,0 m

14. Fitonematóides associados a zingiberales ornamentais em Pernambuco : estimativa do número de amostras para monitoramento, efeito de indutores de resistência e avaliação de mecanismos envolvidos
The expressive increase in production of tropical flowers in Pernambuco indicates the State rising interest in ornamentals. This study had the objectives of: 1) screening plant parasitic nematodes in Zingiberales (Etlingera elatior, Zingiber spectabilis, Alpinia purpurata, Musa coccinea, Tapeinoquilos ananassae e Heliconia spp.) producing areas of Pernambuco

15. Avaliação da espressão de glicoproteinas potencialmente especificas na membrana plasmatica de celulas Natural Killer uterinas de camundogos / Evaluation of expression of potentially specific glycoproteins in plasmatic membrane of mouse uterine Natural Killer
The phenomenon of pregnancy in mammalians with hemochorial type placenta ions where the allogeneic fetus presenting the half of gene from paternal origins growth in tight contact with maternal tissues, without triggering the rejections responses of maternal immune system is still a non-solved question of immunology of reproduction. The cross-talk at maternal

16. Puberty in gilts: I - Use of exogen gonadotrophin (eCG and LH) on the induction and synchronization of first oestrus. II - Effects of flushing on the oestrus cycle before first conception. III - Evaluation of the reproductive performance until first parturition / Puberdade em marrãs: I - Efeito das gonadotrofinas na indução e sincronização do estro à puberdade. II - Efeito do "flushing" alimentar no ciclo anterior à primeira concepção. III - Avaliação da eficiência produtiva e reprodutiva das marrãs até 1º parto
The objective of the study was to investigate in a biotecnical program applied in a commercial breeding unit, the effects of the gonadotrophins (eCG and LH) on puberty estrus inductions and synchronization in gilts followed by their ciclicity. The investigation included the use of flushing on preceding oestrus cycle to first artificial insemination (IA). The

17. ESTUDO DOS ASPECTOS REPRODUTIVOS EM Luehea divaricata Martius (AÇOITA-CAVALO) / STUDIES OF REPRODUCTION ASPECTS IN AÇOITA-CAVALO (Luehea divaricata Martius)
The Luehea divaricata Martius (açoita-cavalo) is a tree of Tiliaceae family that is of the interest of industries due to wood the quality and also reflorestation programs. Studies about propagation are justified mainly when working with native plants, that have few research results. Two studies were conducted about specie propagation: one vegetative way and

18. Estudos reprodutivos, citogenéticos na população de Rhamdia quelen (pisces, Rhamdiidae) do Rio Uberabinha no município de Uberlândia - MG e desenvolvimento de sistema artesanal de recirculação dàgua para criação de peixes
The Uberabinha river in Uberlândia MG, with an urban area predominancy, in its ichthyofauna composition, presents an expressive fish specimens number. It is detached Rhamdia quelen (Jundiá catfish) as a survivor to the city development process and consequently to the pollution. This specie perform an important ecological role, it is eaten up by part of the

19. Reassessment of the role of phospholipids in sexual reproduction by sterol-auxotrophic fungi.
Several genera of oomycete fungi which are incapable of de novo sterol synthesis do not require these compounds for vegetative growth. The requirement for an exogenous source of sterols for sexual reproduction by several members of the Pythiaceae has been questioned by reports of apparent induction and maturation of oospores on defined media supplemented wit

20. Wolbachia-induced parthenogenesis in a genus of phytophagous mites.
The vertically transmitted endosymbiotic bacterium Wolbachia modifies host reproduction in several ways in order to enhance its own spread. One such modification results in the induction of parthenogenesis, where males, which are unable to transmit Wolbachia, are not produced. Interestingly, parthenogenesis-inducing Wolbachia have only been found within hapl

21. The student and the ovum: The lack of autonomy and informed consent in trading genes for tuition
Rising tuition costs have forced university students to become creative in finding ways to fund their education. Some female university students have decided that ova donation may be an acceptable alternative in which to pay for their tuition. This alternative presents itself because of the insufficient number of ova available for assisted reproduction and e

22. Sexual and Apomictic Reproduction in Hieracium subgenus Pilosella Are Closely Interrelated Developmental Pathways
Seed formation in flowering plants requires meiosis of the megaspore mother cell (MMC) inside the ovule, selection of a megaspore that undergoes mitosis to form an embryo sac, and double fertilization to initiate embryo and endosperm formation. During apomixis, or asexual seed formation, in Hieracium ovules, a somatic aposporous initial (AI) cell divides to

23. Aspergillus asexual reproduction and sexual reproduction are differentially affected by transcriptional and translational mechanisms regulating stunted gene expression.
The Stunted protein (StuAp) is a member of a family of transcription factors that regulate fungal development and cell cycle progression. Regulated stuA gene expression is required for correct cell pattern formation during asexual reproduction (conidiation) and for initiation of the sexual reproductive cycle in Aspergillus nidulans. Transcriptional initiatio

24. Bacillus subtilis functional genomics: global characterization of the stringent response by proteome and transcriptome analysis†
The stringent response in Bacillus subtilis was characterized by using proteome and transcriptome approaches. Comparison of protein synthesis patterns of wild-type and relA mutant cells cultivated under conditions which provoke the stringent response revealed significant differences. According to their altered synthesis patterns in response to dl-norvaline,
