Dissection and human specimens study remain the gold standard method for teaching anatomy. Due to the increasing health science courses in Brazil, the traditional way of obtaining bodies for scientific purposes, the unclaimed ones, became insufficient. In addition, this source is no longer ethically appropriate according to anatomists. In order to maintain the teaching quality, the Federal University of Juiz de Fora (UFJF) in Brazil, inspired by successful initiatives around the world, created a body donation program; Sempre Vivo. Besides the bureaucratic difficulty faced during its regulation, the implementation of a body donation program requires special attention regarding the religiosity, culture and uniqueness of the city's inhabitants. Informing people can demystify the process, avoid prejudice and increase the number of donors. In this way, an outreach project was designed to publicize Sempre Vivo and raise public awareness. In the first six years, Sempre Vivo reached the mark of 64 registered donors and seven bodies received. The donor’s profile corresponds to female (70.3%), 57 years of age, retired (50.8%), spiritist (53.1%) and with 12 years or more of formal education (90.6%). Considering that the UFJF has not received unclaimed bodies for ten years, the program was considered satisfactory up to this level and, in the future, it may be the exclusive source of anatomical specimens. The description of the creation and the publicizing of Sempre Vivo, the overcome challenges, as well as the donors’ profile, may encourage and facilitate the foundation of similar programs in Brazil and abroad.

Objectives:
This study evaluated the dentinal penetration depth of 2.5% sodium hypochlorite (NaOCl) in root canals with and without preparation and different irrigant activation protocols.
Materials and Methods:
Sixty-three bovine mandibular incisors were randomly allocated to 6 groups (n = 10): G1, preparation + conventional needle irrigation (CNI); G2, preparation + passive ultrasonic irrigation (PUI); G3, preparation + Odous Clean (OC); G4, no preparation + CNI; G5, no preparation + PUI; G6, no preparation + OC; and CG (negative control; n = 3). Samples were filled with crystal violet for 72 hours. Irrigant activation was performed. Samples were sectioned perpendicularly along the long axis, 3 mm and 7 mm from the apex. Images of the root thirds of each block were captured with a stereomicroscope and analyzed with an image analysis software. One-way analysis of variance, followed by the Tukey post hoc test, and the Student’s t-test were used for data analysis, with a significance level of 5%.
Results:
The NaOCl penetration depth was similar when preparation was performed, regardless of the method of irrigation activation (p > 0.05). In the groups without preparation, G6 showed greater NaOCl penetration depth (p < 0.05). The groups without preparation had a greater NaOCl penetration depth than those with preparation (p = 0.0019).
Conclusions
The NaOCl penetration depth was similar in groups with root canal preparation.Without root canal preparation, OC allowed deeper NaOCl penetration. The groups without preparation had greater NaOCl penetration than those undergoing root canal preparation.

Trypanosomiasis is caused by a pathogenic protozoan of the genus Trypanosoma, being Trypanosoma vivax the most important agent for cattle. The aim of the present study was to demonstrate the expansion of T. vivax infection in different mesoregions of Minas Gerais, Brazil, and describe the clinicopathological findings of trypanosomiasis in cattle. The diagnosis was based on visualization of the parasite in blood smears and DNA detection of T. vivax in the blood of live cows and tissues of necropsied animals by the polymerase chain reaction (PCR). Thirty suspected herds were tested, of which 11 were positive for T. vivax. The most frequent clinical signs were anemia, apathy, drop in milk production, weight loss, reproductive disorders, and nervous signs. Concomitant diseases, such as malignant edema, pneumonia and increased cases of mastitis were associated with T. vivax infection. Three cows were necropsied and the most significant findings were low body condition score, pale mucous and spleen with white pulp hyperplasia. The results demonstrated the expansion of T. vivax infection in Minas Gerais, that PCR-associated blood smears are promising for diagnosis, and that other diseases often occur concomitantly to T. vivax infection in regions with trypanosomiasis in cattle.
