Perfil de acidentes envolvendo risco biológico em profissionais de saúde de Araçatuba-SP: uma caracterização dos envolvidos

Each year individuals have sought a better quality of life and work, in this case, the science of Bio-insurance needs to keep up with technological advances and the needs of society to minimize or eliminate the risks of accidents. This study evaluated the most common accidents involving health staff from 2007 to 2011 in Araçatuba-SP. 478 accidents were recorded, and 78.7% with percutaneous involvement, 9% with intact skin, 4% with no skin intact, with 7.3 mucous and 1.05% other types of exposures. Most accidents were caused by needles with lumen (68.0%), followed by other agents (14.1%), accidents with blades (8.5%) or needles without lumen (5.5%); 3.7% did not answer and 0.2% were accidents with glasses. When checking the condition in which the accident occurred, 26.0% did not specify, 25.1% occurred in the disposal and / or handling sharp objects, 12.0% at the time of drug administration, 6.9% puncture, 3.7% occurred during recapping the needle. These data show that the most common accidents are those involving needles with lumen and / or sharp objects and due to these factors, the industry of health materials have sought alternatives to minimize such accidents as needles with protective, vacuum collection . Thus, it appears that reporting accidents is important for the development of technical and / or safer materials for patients and health workers.

Ocorrência de lesões de ligamentares e músculo tendíneas ao longo das fases do ciclo menstrual de atletas de alto redimento: um estudo de caso longitudinal

Female athletes are more susceptible to injury when compared with males. This increased risk of injury, may be caused by fertile-menstrual cycle. The aims of this study were to investigate the prevalence in the occurrence of muscle-tendon and ligament injuries in different phases of the menstrual cycle over a period of high performance sports training and identify possible differences of occurrences between the phases. Fifteen female athletes, members of a women's basketball team, with ages between 15 and 22 years (average 17.5 ± 2.6 years), with regular menstrual cycles and daily practitioners of training, received follow-up during the menstrual cycle for 5 months. During the period were noted occurrences of injury in relation to the menstrual period of each athlete. The results showed 13 injuries, all of anterior cruciate ligament. The distribution of percentage values indicated a significantly higher risk of athletes suffer injuries in the follicular phase. The result makes us believe that significant elevations in the concentrations of estrogen in this fertile menstrual cycle phase, more open women to a higher risk of performing different injuries.

Detecção molecular do rearranjo Line-1 /c-Myc em tumores venéreos transmissíveis caninos espôntaneos

Transmissible venereal tumor (TVT) is a neoplasia that develops naturally in dogs. It can be easily transplanted, which demonstrates its ability to spread from animal to animal. Since the Linr-1/c-MYC rearrangement in TVT cells had not been studied at the Veterinary Hospital of the Veterinary School, Unesp in Botucatu, SP, this study aimed to detect this genetic alteration specific to this kind of tumor by means of the polymerase chain reaction (PCR). Twenty dogs with cytological diagnosis of TVT were used. Samples of neoplastic cells were collected to determine the presence of the Line-1/c-MYC marker. The rearrangement characterized by 340bp amplicons did not vary, in agreement with previous studies using the same methodology. This contributed to a more precise identification of persistent tumor cells in cases in which gross or microscopical detection was not possible.

Principais mecanismos envolvidos na maturação oocitária em bovinos: da oogenese a maturação in vitro

Despite the efforts made to improve the production of bovine embryos in vitro, their efficiency is still low, since only 30-40% of developed blastocysts are obtained from oocytes after in vitro maturation (IVM), fertilization and cultured embryos. Assisted reproductive technologies have a limiting impact due a lack of oocytes capable to fertilization.The comprehension of mechanism involved in oocyte maturation are crucial to establish a culture system that allows a larger number production of good quality embryos. The study of the early stages of oocyte and follicle development in vivo is important for a better understanding of the molecular pathways that regulate oogenesis, folliculogenesis and oocyte maturation. Thus the physiological biochemical and molecular mechanisms involved in maturation may contribute to the increased efficiency of in vitro embryo production. Therefore, the aim of this literature review is to understand the basic mechanisms that underlie oocyte maturation in cattle, since oocyte and follicle cells in vivo formation to its use in the in vitro environment.

Detecção imunoistoquímica de receptores de estrógeno e progesterona no endométrio de vacas Nelore (Bos taurus indicus) durante o anestro pós-parto

Twenty-four postpartum anestrous Nelore purebred cows were used in the study. Anestrous was determined based on the reproductive history which was confirmed in each cow based on plasma progesterone concentration and by transrectal ultrasonography. Endometrial biopsies were collected. The animals were separated into two groups according to maximum follicular diameter- Group 1: follicles <6mm (n=12) and Group 2: follicles >-6mm follicles (n=12). The immunohistochemistry technique was employed to evaluate the presence of estrogen and progesterone receptors in the uterine glandular epithelium and stroma. High counts of positive nuclei and high intensity of immunostain for estrogen and progesterone receptors in the glandular epithelium and stroma were observed in the two groups. However, the immunostain intensity of progesterone receptors in the glandular epithelium was higher in Group 2 compared to Group 1. When glandular epithelium and stroma were compared within each group, the relative number of estrogen receptors in the Group 1 was higher in the glandular epithelium compared to stroma and the immunostain intensity for the progesterone receptor in Group 2 was higher in the glandular epithelium compared to stroma. The results suggest that the mechanisms that control the expression of endomerial receptors in the anestrus are similar to the ones observed during the estrus cycle.
