No presente trabalho, foram utilizadas 21 fêmeas suínas, virgens, sexualmente aptas, criadas e mantidas sob condições industriais, para observação dos perfis hormonais séricos de 17-alfa-OH progesterona e androstenediona, durante o ciclo estral. As colheitas de sangue foram efetuadas sempre no mesmo intervalo, entre 8 e 10 horas. Cada animal foi submetido a 14 punções venosas, distribuídas nos dias zero, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 21, 22 e 23 do ciclo estral. Considerou-se o dia zero como o primeiro dia da fase estral, e o 23º dia como o primeiro do estro subseqüente. Os ensaios para dosagens hormonais foram executados utilizando-se a técnica de radioimunoensaio (RIE) em fase sólida e para isso foi empregado conjunto de reagentes comerciais (Coat-A-Count®). Para o hormônio 17-alfa-OH progesterona, foram encontrados valores médios que variaram entre 0,18 e 2,7 ng/ml e para o hormônio androstenediona esses valores oscilaram entre 0,08 e 0,24 ng/ml.

The influence of additions of 2, 4, 6, 8, 10 and 12 wt.% Ag in the isothermal aging kinetics of the Cu-8 wt.% Al alloy was studied using microhardness measurements, differential scanning calorimetry, optical and scanning electron microscopy and X-ray diffractometry. The results indicate that the presence of silver is responsible for the shift of the equilibrium concentration to higher Al contents, allowing the formation of the gamma(1) phase (Al4Cu9) in this alloy. For Ag additions up to 6% the dominant kinetic process is Ag precipitation and for additions from 8 to 12% Ag the nucleation of the perlitic phase dominates. (C) 2003 Elsevier B.V. B.V.

Seis cabras lactantes foram distribuídas aleatoriamente em um delineamento experimental em crossover, em dois grupos: sob condições termoneutras e estresse térmico. Um período de adaptação de 28 dias foi seguido por quatro períodos de 14 dias cada, quando os animais sob estresse térmico foram expostos à temperatura média de 33,84ºC; THI de 86,20; BGT de 36,18 e BT de 32,11ºC das 8 às 17 horas, incluindo radiação solar simulada das 10 às 15 horas. Não houve diferença entre as concentrações plasmáticas de progesterona, mas as fêmeas submetidas ao estresse térmico apresentaram diminuição nas concentrações plasmáticas de estradiol, quando comparados ao grupo termoneutro. A temperatura retal dos animais sob estresse térmico foi mais elevada quando foi comparada à do grupo de animais em condições de termoneutralidade. As cabras mantiveram as concentrações plasmáticas da progesterona, com diminuição na secreção de estradiol, quando expostas a um estresse repetido e intermitente, a despeito de ocorrer hipertermia durante o estresse pelo calor.

Thirteen cows, Bos indicus, of the Nellore breed were superovulated with 22 mg of follicle stimulating hormone (FSH) administered by intramuscular route during four consecutive days (D10, D11, D12 and D13), starting on the 10th day of the estrous cycle (day 0 = estrus). Prostaglandin (PGF2alpha, 1.0 mg, im) was administered on D12, 48 h after the first FSH injection, for the induction of estrus on D14, when artificial insemination was performed. Seven days later (D21 of the cycle), embryos were collected, and evaluated, and the ovarian response was estimated on the basis of number of corpora lutea determined by rectal palpation. Blood samples were obtained for the determination of plasma 17-beta estradiol on D10, D11, D12, D13, D14 and D21 and plasma progesterone on D14 by RIA. The donors were divided into two groups according to progesterone levels on D14, the day of the induced estrus (GI: P4 less-than-or-equal-to 1.00 ng/ml, N = 5 and GII: P4 > 1.00 ng/ml, N = 8). A linear positive correlation was observed between plasma 17-beta estradiol concentration on the day of estrus and viable embryo number. We conclude that plasma 17-beta estradiol and progesterone concentrations on the day of estrus can be used to predict the viability of embryos recovered from Nellore cows superovulated with FSH.

In the present study 21 young swine females, sexually mature, reared and kept under an industrial management system were assessed for cortisol and oestradiol-17 beta serum prolifes during the oestrus cycle. Blood sampling was performed always at the same interval, from 8:00 to 10:00 a.m. Each animal was submitted to 14 venal punctions at days 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 21, 22 and 23 of the oestrous cycle. The first day of the oestrous phase was assumed to be day 0 and the 23(rd) as the first of the next cycle. Hormone determinations were performed using a solid phase radioimmunoassay (RIA). Regarding to cortisol concentrations, there was a variation from 3.5 to 8.0 mu g/dl and for oestradiol-17 beta the mean values detected varied from 3.5 to 14.9pg/ml.

The total synthesis of 8,9-licarinediols was selectively carried out from licarin A, previously obtained by oxidative coupling of (E)-isoeugenol. The corresponding enantiomerically pure (+)- and(-)-licarin A ester derivatives were subjected to Sharpless oxidation to yield the asymmetric C-8, C-9 dihydroxylation products, whose absolute configurations were established by means of the CD and NMR spectroscopic analyses of their Mosher ester derivatives.

In bovine females the release of prostaglandin F 2α (PGF 2α) is induced in vivo by estradiol (E 2). It is believed that E 2 stimulates the synthesis of essential proteins for the production of PGF 2α. This study aimed to evaluate the effect of E 2 in increasing the concentration of total protein and modifying the protein composition of endometrial explants from bovine females treated with E 2 at the 17 th day of estrous cycle. Crossbred heifers were treated at 17 th day of estrous cycle intravenously with 0 mg (Control Group; n = 6) or 3 mg of E 2 (E 2 Group; n = 6) and killed two hours after. Endometrial explants were isolated, subjected to extraction of total protein, quantified and were analyzed by onedimensional electrophoresis on polyacrylamide gel 10% SDS-PAGE. The concentration of total protein did not differ between groups, 6296.10 + 439.90 μg/mL for the Control Group and 8426.56 + 1156.00 μg/mL for E 2 Group (p = 0.1158). There was no significant difference (p > 0.05) in the protein profile of endometrial explants in gels stained with Coomasie Blue. In gels stained with Silver Nitrate it was verified in E 2 Group greater relative percentage of the bands referring to the molecular weight of 75 to 76 kDa (8.40% vs. 4.89% in E 2 Group and Control respectively; p < 0.05) and 108 to 110 Kda (6.85% vs. 3.84% in E 2 Group and Control respectively, p < 0.05). It was observed in E 2 Group lower relative percentage of the band referring to the molecular weight of 90 kDa (5.78% vs. 9.83% in E 2 Group and control respectively; p < 0.05). We concluded that the E 2 does not increase the protein concentration in the endometrium, however, it modifies the proteinic composition in the endometrial explants, indicating that E 2 alters the expression of specific proteins.

Results are presented of a search for the production of new particles decaying to pairs of partons (quarks, antiquarks, or gluons), in the dijet mass spectrum in proton-proton collisions at √s=8 TeV. The data sample corresponds to an integrated luminosity of 4.0 fb-1, collected with the CMS detector at the LHC in 2012. No significant evidence for narrow resonance production is observed. Upper limits are set at the 95% confidence level on the production cross section of hypothetical new particles decaying to quark-quark, quark-gluon, or gluon-gluon final states. These limits are then translated into lower limits on the masses of new resonances in specific scenarios of physics beyond the standard model. The limits reach up to 4.8 TeV, depending on the model, and extend previous exclusions from similar searches performed at lower collision energies. For the first time mass limits are set for the Randall-Sundrum graviton model in the dijet channel. © 2013 CERN.
