1. Efeito de diferentes combinações hormonais sobre a taxa de retorno ao cio e prenhez em vacas de corte lactando, submetidas a inseminação artificial em tempo fixo / Effect of different hormonal combinations on the return to estrus and pregnancy rate in lactating beef cows, submitted to a fixed time insemination
Os protocolos de sincronização de estro e ovulação em vacas de corte lactantes buscam promover um rápido retorno a ciclicidade e com isso, reduzir intervalo parto-concepção. Entretanto, o bom desempenho reprodutivo dos animais depende em grande parte, da condição nutricional dos rebanhos. Este estudo teve o objetivo de avaliar o efeito dos hormônio

2. 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

3. Combined Transdermal Testosterone Gel and the Progestin Nestorone Suppresses Serum Gonadotropins in Men
Context: Testosterone (T) plus progestin combinations are the most promising hormonal male contraceptives. Nestorone (NES), a progestin without estrogenic or androgenic activity, when combined with T may be an excellent candidate for male contraception.

4. Conditional mouse models demonstrate oncogene-dependent differences in tumor maintenance and recurrence
Diversity in the pathophysiology of breast cancer frustrates therapeutic progress. We need to understand how mechanisms activated by specific combinations of oncogenes, tumor suppressors, and hormonal signaling pathways govern response to therapy and prognosis. A recent series of investigations conducted by Chodosh and colleagues offers new insights into the

5. Hormonal and gravitropic specificity in the regulation of growth and cell wall synthesis in pulvini and internodes from shoots of Avena sativa L. (oat).
Segments can be cut from the peduncular-1 internode of oat (Avena sativa L.) shoots so as to contain the graviresponsive leaf-sheath pulvinus and gibberellin-sensitive internodal tissue. Incorporation of [14C]glucose was used to monitor cell wall synthesis in these two tissues as affected by gravistimulus, indoleacetic acid (IAA), gibberellic acid (GA3), and

6. Transcriptional Down-Regulation by Abscisic Acid of Pathogenesis-Related β-1,3-Glucanase Genes in Tobacco Cell Cultures1
Class I isoforms of β-1,3-glucanases (βGLU I) and chitinases (CHN I) are antifungal, vacuolar proteins implicated in plant defense. Tobacco (Nicotiana tabacum L.) βGLU I and CHN I usually exhibit tightly coordinated developmental, hormonal, and pathogenesis-related regulation. Both enzymes are induced in cultured cells and tissues of cultivar Havana

7. Exposure of human islets to cytokines can result in disproportionately elevated proinsulin release
Infiltration of immunocytes into pancreatic islets precedes loss of β cells in type 1 diabetes. It is conceivable that local release of cytokines affects the function of β cells before their apoptosis. This study examines whether the elevated proinsulin levels that have been described in prediabetes can result from exposure of β cells to cytokines. Human

8. Heparin and hormonal regulation of mRNA synthesis and abundance of autocrine growth factors: relevance to clonal growth of tumors.
Highly sulfated, heparinlike species of heparan sulfate proteoglycans, with heparinlike glycosaminoglycan chains, are extracellular matrix components that are plasma membrane bound in growth-arrested liver cells. Heparins were found to inhibit the growth and lower the clonal growth efficiency of HepG2, a minimally deviant, human hepatoma cell line. Heparan s

9. Disengaging insulin from corticosterone: roles of each on energy intake and disposition
Corticosterone and insulin play complex roles in the amount and composition of calories ingested, and the utilization and deposition of this energy. Understanding the interplay of these two hormones is complicated because increasing concentrations of corticosterone dose-dependently increase circulating insulin levels. We addressed individual contributions of

10. Germination and Dormancy of Abscisic Acid- and Gibberellin-Deficient Mutant Tomato (Lycopersicon esculentum) Seeds (Sensitivity of Germination to Abscisic Acid, Gibberellin, and Water Potential).
Germination responses of wild-type (MM), abscisic acid (ABA)-deficient (sitw), and gibberellin (GA)-deficient (gib-1) mutant tomato (Lycopersicon esculentum Mill. cv Moneymaker) seeds to ABA, GA4+7, reduced water potential ([psi]), and their combinations were analyzed using a population-based threshold model (B.R.
