Uso de LH ou eCG no último dia do protocolo superovulatório em bovinos

In the last decades several hormonal treatments to induce multiple ovulation and embryo transfer (MOET) have been developed. Tight control of the time of ovulation allowed the use of fixed-time artificial insemination (FTAI) in bovine embryos donors, facilitating animal management. Although, protocols that allow FTAI have evolved and yield as much embryo as conventional protocols that requires estrus detection, substantial increase in viable embryo production has not been observed in superestimulated bovine cattle. The present review put emphasis on superestimulatory protocols in wich the last two doses of pFSH are replaced by eCG or LH. Recent results indicate that an extra LH stimulus (using eCG or LH), on the last day of P-36 superestimulatory treatment, seems to improve transferable embryo yield in both Bos taurus and Bos indicus cattle.

Características morfogênicas e estruturais da Brachiaria brizantha cv. Marandu submetida a diferentes doses de nitrogênio e alturas de resíduos

The objective of this study was to evaluate the rate of leaf appearance, leaf elongation rate, number of green leaves, length of blade and stem of Brachiaria brizantha cv. Marandu under different nitrogen levels and two residue heights. A randomized block design was used in a 4 x 2 factorial scheme, four doses of nitrogen (100, 200, 300 and 400 kg N ha(-1) year(-1)) and two residue heights (5 and 15 cm). There was significant interaction between residue height and nitrogen levels for leaf appearance rate of signal grass, which was influenced negatively and linearly by the residue heights being observed an average reduction of 28.20% from lower to higher residue. There was no interaction between the levels of nitrogen x residue height on the number of green leaves. The dosage that provided the highest stalk in the residue height of 5 cm was of 271.5 kg N ha(-1). An increase of 0.0745 cm tiller(-1) day(-1) for 1 kg of N ha(-1) applied to height of 15 cm of residue was observed. Nitrogen fertilization contributes positively to growth and development of rates of appearance and leaf extension. The management of pasture of Brachiaria brizantha cv. Marandu with 5 cm of residue and fertilization with 100 kg N ha(-1) provided better answer morphogenic traits.

Laser terapêutico no reparo ósseo de ratos submetidos à ausência de carga

Low-intensity laser has been used as a physical agent in various fields of medical sciences such as bone and tissue repair. Meanwhile little is known about its effects in adverse conditions such as abolition of load and osteopenic. With the assumption that the laser Ga-Al-As accelerates the process of bone consolidation, goal of this study was to evaluate bone mineral density (BMD) in incomplete transverse osteotomies of tibia in adult rats, treated with low power laser therapy in three different groups: G1 (n = 10), reference 15 days; G2 (n=10), suspended by the tail and, accordingly, treated with laser for 12 days; G3 (n = 10), suspended by the tail by 36 days and that after 21 days, there was laser treatment for 12 days. The right tibia treated with laser and left served as control. The laser was used to Ga-Al-As, DMC - Flash Lase® III, with wavelength 830nm, 100 mW, 4J, 140 J / cm ², 40s of application in 12 sessions. It was used densitometer-Lunar DPX®, with computer program for "small animals", and the analysis of BMD was made in the bone throughout the region and the osteotomy. The results showed no efficacy of laser therapy in the process of bone repair, both in animals of group 1, as in group 2 and 3. It follows that either the low-power laser was not an effective performance or the effects of laser therapy is not only manifested at the site of irradiation as well as the systemic level.

Influência do aumento do comprimento de implantes dentários

The use of implants of greater length may be more favorable for the predictability of dental implants. This statement is relevant, since the cause of failures in dental implants are more related to biomechanical complications. The aim of this study was to evaluate the influence of increase of the length around the entire body of the implant. Six models were created with the presence of only one hexagonal implant (Master Screw connection, Implant Systems, São Paulo, Brazil) of 3.75 mm x 7.0 mm (Model A), 3.75 mm x 8.5 mm (Model B ), 3.75 mm x 10.0 mm (Model C) 3.75 mm x 11.5 mm (Model D) 3.75 mm x 13.0 mm (Model E) 3.75 mm x 15.0 mm (Model F) using the method of photoelasticity. The results were visualized through a qualitative analysis of stresses (number and intensity photoelastic fringes). The model A showed a pattern of less favorable stress distribution, the oblique loading was the most detrimental to the related structures. Conclusion: The increased length allowed for a better distribution of stresses. The oblique loading was more detrimental when compared to axial loading.

A influência do anel na evolução ponderal após quatro anos da derivação gátrica em Y-de-Roux laparoscópica

Use of ring in Roux-en-Y gastric bypass is still a matter of controversy among bariatric surgeons. There is no consensus on its impact in relation to weight loss and weight maintenance in the long term. AIM: To evaluate the influence of the ring on the evolution of body weight over four years after bariatric surgery. METHODS: Retrospective analyzis of 143 women who underwent laparoscopic Roux-en-Y gastric bypass paired on the use or not use of Silastic® ring. Follow-up time was 48 months. Inclusion criteria were age over 18 years, primary bariatric operation and regular attendance at the clinic during the period of interest for research. The technique kept small gastric reservoir estimated in a volume of 30 ml. The food limb had in average 150 cm and the bile one 40 cm from the duodenojejunal angle. The group "ring" used Silastic® device with length of 6.5 cm, placed 2 cm from gastrojejunal anastomosis. The ring was closed for five polypropylene surgical thread sutures. In the morning after surgery the patients received isotonic fluids; on the second day salty liquid diet and were discharged on the third day. Semisolid diet started from the 20th day and solid on the 30th, with daily tablet of polivitamins. RESULTS: The weight loss was larger on the ring than without ring groups in all periods, respectively 10% and only 5% in the third postoperative year. The proportion of not having reached the 50% excess weight loss expectative was significantly higher in the group without ring than in the group with the ring (31% and 8% respectively in the fourth year). There was no difference between groups in delayed recovery of weight lost with the operation. CONCLUSIONS: The results were favorable to use the ring exclusively when it is analyzed only the weight loss.

Centro da atividade modelo centro-dia do idoso no município de Presidente Prudente

This final work graduation presents a proposal model Seniors Center Day in the city of Presidente Prudente. The municipality has local (private and public) with socialization activities and some medical treatments for the elderly, but the attendance capacity is not sufficient and in some places the infrastructure is not adequate, as in Case Study Centro de Referência do Idoso Feliz Idade maintained by Presidente Prudente Prefecture. From projective references created the model Centro da Atividade that integrates users in the city through the spatial continuity (main architectural party) and physical and psychological comfort of the elderly. The space designed has strong links with the external environment, creating relationships of older people with nature through living spaces to free up and the psychological comfort (and the relation with nature) is present in the project through spaces with elements that make part of the affective memory of users

Efeito da altura do obstáculo na ultrapassagem de múltiplos obstáculos de idosos com doença de Parkinson

A doença de Parkinson (DP) acarreta em déficits sensoriais e comprometimentos motores, tornando mais desafiador a ultrapassagem de obstáculos. Tropeços durante a ultrapassagem de obstáculos é um dos principais motivos das quedas de idosos com DP. A presença de obstáculos durante o andar é comum no dia-a-dia das pessoas. Mudanças na altura dos obstáculos podem gerar instabilidade durante a ultrapassagem do obstáculo, o que aumenta o risco de contato com o obstáculo e, consequentemente, o risco de tropeços e quedas. Ainda, ambientes mais complexos, por exemplo, com mais de um obstáculo, aumentam a exigência dos sistemas sensorial, atencional e motor. Entretanto, até o momento, nenhum estudo analisou o andar de idosos com DP durante a ultrapassagem de mais de um obstáculo. O objetivo do presente estudo é investigar a influência da ultrapassagem de dois obstáculos nos parâmetros espaciais e temporais do andar de idosos com DP, considerando o efeito da altura do obstáculo (obstáculo baixo e alto). Participaram do estudo 20 idosos com DP com estágio da DP até 3 na escala de Hoehn & Yahr. Na realização da tarefa do andar, o idoso percorreu andando uma distância retilínea de 8 m sobre uma passarela com 0,79 m de largura. A instrução dada ao participante foi de realizar a tarefa de andar na sua velocidade preferida até o final da passarela. Cada participante realizou um total de 12 tentativas (3 tentativas para cada condição) nas seguintes condições: andar com ultrapassagem de um obstáculo de 5 cm; andar com ultrapassagem de um obstáculo de 15 cm; andar com ultrapassagem de dois obstáculos de 5 cm; andar com ultrapassagem de dois obstáculos de 15 cm. A ordem de apresentação dos blocos foi randomizadas entre os participantes. Os parâmetros espaçotemporais do andar foram coletados por meio do GAITRite® e um sistema optoeletrônico, com frequência de 100 Hz. Os parâmetros analisados foram comprimento (cm)...

Prevenção da repetição de episódos de reação tipo 2 da Hanseníase com o uso da talidomida na dose de 100mg/dia

Introdução: A hanseníase é doença crônica que pode ter seu curso interrompido por episódios reacionais tipo 1 e 2 ou ENH, sendo que estes podem ser repetitivos, com conseqüentes danos ao paciente.A talidomida é a medicação de eleição para o controle, desde 1965. Objetivo: Evitar repetição de episódios reacionais. Material e Método: Após o controle da reação com dose tradicional, utilizou-se 100mg/d, pelo período de seis meses, com acompanhamento por seis meses após a suspensão. Resultados: Foram avaliados 42 pacientes MB, 39 (92,85%) da forma V e 3(7,15%) da D, que apresentaram ENH, como primeiro episódio ou repetição, 33(78,6%) do sexo masculino e9(21,4%) do feminino. As idades variaram de 18 a 84 anos, predomínio acima de 49 anos.Não se observou repetição em 100% dos pacientes durante o uso dessa dose.Durante a observação clinica, 33(78,6%)continuaram sem apresentar reação e9(21,4%), todos da forma V,a apresentaram, de forma leve,sem sinais e sintomas, controlada com antinflamatórios não hormonais. Não houve efeitos adversos. Conclusões: sugere-se o uso da talidomida, 100mg/ dia, como manutenção, que foi efetiva, impedindo a repetição das reações tipo 2.

Diâmetro folicular e taxa de prenhez em protocolo de sincronização com GnRH ou Benzoato de Estradiol no dia 0 em vacas de corte

This work aimed to evaluate the pregnancy rate and follicular diameter using EB or GnRH on the insertion of progesterone implant (D0) in lactating beef cows. Two groups were tested in two experiments. In Exp. 1 were used 61 Nelore cows divided into two groups: G-BE (n = 32) and G-GnRH (n = 29), on D0 was inserted P4 implant (CIDR ) and applied 2 mL of BE (G-BE) or 2.5 mL GnRH (G-GnRH). In D9 was performed ultrasonography (U.S.) to measure the diameter of the dominant follicle (DF) present in the ovary and the implant was removed, with concomitant administration of 2.5 mL of PGF2a and estradiol cypionate (ECP ) followed by calves removal. After 48 hours all the cows were inseminated and the calves returned. In Exp. 2 50 cows were used following the same protocol described above, but the pregnancy was assessed without performing ovarian US. There was no difference (p>0.05) in pregnancy rate between treatments, BE (55%) or GnRH (41%), but the follicular diameter was significantly higher (p<0.05) in pregnant cows treated with EB (10.7 mm vs. 8.5 mm) and in cows treated with GnRH there was no difference (p>0.05) between pregnant and no pregnant cows (11.6 mm vs. 10.2 mm). We concluded the use of GnRH on D0 did not improve the pregnancy rate in lactating beef cows and follicular diameter was greater (p <0.05) in pregnant cows compared to non-pregnant only in G-BE.

Vibração de plantas de pimenta Malagueta para produção de frutos e sementes em ambiente protegido

This study aimed to verify the effect of vibration of plants in the production of fruits and seeds and in the physiological quality of the seeds of the “Malagueta” pepper in a protected cultivated area with open and closed sides. The experiment was conducted at the Experimental Farm of the School of Agronomic Sciences of Universidade Estadual Paulista (FCA/UNESP), located in the city of São Manuel (SP). Two treatments were carried out, which consisted of plants that did and did not undergo vibration. Plants were vibrated manually by swinging the wire attached to the supporting bamboo for about 5 seconds, twice a day for 11 weeks. The design was a randomized block with six repetitions. The same experiment was conducted in two protected environments, with and without anti-aphids screens on the sides, cultivated in the same season. For the comparison of environments, a combined analysis was performed considering each environment as a separate experiment. The characteristics evaluated were: weight and number of fruits per plant; weight, diameter and length of fruit; weight and amount of seeds per fruit; and plant height. For the analysis of seed quality, the characteristics evaluated were: germination percentage; first count of germination; dry matter of seedlings; seedling emergence in substrate; and seedling emergence speed index. Regardless of the environment, vibration affects the physiological quality of seeds. The presence of pollinator insects benefited the production and quality of “Malagueta” pepper seeds and increases the fruit weight.
