Efficiency of superstimulatory protocol P-36 associated with the administration of eCG and LH in Nelore cows

Recent work with P-36 demonstrates that the replacement of the last two doses of Follicle-Stimulating Hormone (FSH) with equine chorionic gonadotropin (eCG) increases embryo yields. However, it is unclear if the positive effect of eCG is related to its FSH-like activity, LH-like activity, or both. This study aimed to verify the replacement of eCG with pLH on the last day of superstimulatory treatment. Twenty-five Nelore cows were allocated to four groups: P-36 (control), P-36/eCG, P-36/LH2, and P-36/LH4. All animals underwent four treatments in a crossover design. The control group cows were superstimulated with decreasing doses of porcine Follicle-Stimulating Hormone (pFSH, 133 mg, im). In the P-36/eCG, P-36/LH2, and P-36/LH4 groups, the last two doses of pFSH were replaced in the former group by two doses of eCG (200 IU each dose, im) and in the latter two groups by two doses of pLH (1 and 2 mg each dose, im), respectively. Donors received fixed-time artificial insemination 12 and 24 hours after pLH. Embryo flushing was performed on D16. Data were analyzed by ANOVA (Proc Mixed, SAS). There was a trend of decreasing ovulation rate when comparing groups LH2 and eCG (P = 0.06). However, there was no significant difference in the mean number of viable embryos among groups P-36 (3.3 ± 0.7), P-36/eCG (4.5 ± 0.5), P-36/LH2 (3.7 ± 0.8), and P-36/LH4 (4.2 ± 1.0). It is concluded that the replacement of eCG by pLH on the last day of superstimulatory treatment can be performed with no significant variation in the production of viable embryos.

Odontoma em pacientes odontopediátrico: diagnóstico e tratamento. Relato de caso clínico.

Odontoma is a term that refers to a benign tumor of odontogenic and mixed nature, composed of epithelial and mesenchymal components. Histologically, they are compounds of different configurations including dental enamel, dentin, cementum and in some cases the pulp tissue. A slow growing asymptomatic tumor, odontoma is usually discovered through routine radiographic examination. A 3-year old male patient sought care at the School of Dentistry’s Baby Clinic (UNESP-Araçatuba), complaining of “small ball close to the teeth.” During the interview, the mother reported that the lesion was observed soon after a trauma, and evolved in less than one month. An ulcerated lesion with a 0.8 cm diameter was found during intraoral clinical examination. It was located in the inferior and anterior region of the mouth, between teeth 81 and 82, and there was also crown distalization. A radiographic examination showed a radiolucent area and root distance. In the absence of clinical and radiographic characteristics suggesting a case of odontoma, the differential diagnosis was peripheral giant cell lesion and pyogenic granuloma. So the area was punctured. Nonetheless, due to the absence of liquid, the surgical removal of the lesion was performed, followed by histological examination, which showed the definite diagnosis of a suggestive case of emerging odontoma.

Liderança e assédio moral: a administração perversa do sentido do trabalho

Harassment at work is not a recent phenomenon. However, have been widened-discussions on the question, its causes and factors organizational intimately linked to it. This article brings to light the concept of harassment moral the scope of work and makes reflections on the management models and leadership, and how to trigger this process, at the same time, it questions the alternatives to minimize the impact of this problem through a conscious and participative management, by creating and of spaces and educational policies, valuing if the worker and building an environment ethic of work. In addition, propose alternatives of prevention of harassment, by means of leadership with the contribution of psychologist organizational and work.

Sucessão estratigráfica e tratos de sistemas do Membro Romualdo, porção leste da Bacia do Araripe, nordeste do Brasil

Located in northeastern Brazil, the evolution of Araripe Basin has been associated with the fragmentation of Gondwana and opening of the South Atlantic. The Santana Formation belongs to the post-rift sequence of the basin and is characterized by the presence of laminated limestones in the lower portion (Mb. Crato), evaporite (Ipubi) and siliciclastics (Mb. Romualdo). For better understanding of the Romualdo's stratigraphy, depositional environments and tract of systems, a stratigraphic analysis was made with representative columnar sections of the unit. Sedimentary facies have been described in detail, as well as paleocurrents measured at different stratigraphic levels. It was found that the contact of Mb. Romualdo with the carbonate-evaporite section (Mbs. Crato and Ipubi) is a unconformity, evidenced by residual lags and thin layers of conglomerates above the contact. Above the conglomeratic levels predominate fine sandstones / medium interlayered with calciferous green shales. The percentage of shales increases towards the top, featuring retrogradational stacking culminating in layers of coquinas, excellent stratigraphic mark in the basin. Thin layers of coquins of gastropods comprising equinoids, located on the shale section, present in three sections marine deposits are associated with surfaces ravine. The upper section is characterized by recurrent facies of green shales, sandstones intercalated with sandstones progressively become more frequent towards the top of the unit, featuring the regressive part of the cycle. The sandstones present cross-stratification, often with mud clasts and clay layers in the foresets, and beddings of flaser type and wavy in heterolitic facies, suggesting the action of tidal currents. Paleocurrents measured in the sandstones show gaps with opposite flow directions outlining bipolar standards, which reinforce the interpretation of shallow marine environment influenced by tides during the sedimentation...
