A neural network is a mathematical model that is able to perform a task automatically or semi-automatically after learning the human knowledge that we provided. Moreover, a Convolutional Neural Network (CNN) is a type of neural network that has shown to efficiently learn tasks related to the area of image analysis, such as image segmentation, whose main purpose is to find regions or separable objects within an image. A more specific type of segmentation, called semantic segmentation, guarantees that each region has a semantic meaning by giving it a label or class. Since CNNs can automate the task of image semantic segmentation, they have been very useful for the medical area, applying them to the segmentation of organs or abnormalities (tumors). This work aims to improve the task of binary semantic segmentation of volumetric medical images acquired by Magnetic Resonance Imaging (MRI) usi...

The aim of this study was to determine the programmes of parasite and sanitary control and knowledge of the parasite diseases that affect dogs and cats of 306 owners of the city of Escárcega, state of Campeche, Mexico. The total number of pets was 590 dogs and 149 cats. Each household has an average of 1.92 dogs or 0.48 cats with ages of 2.9 and 2.8 years, respectively. Most owners of dogs (30.8%) and cats (25.6%) apply some anthelmintic treatment twice a year. The frequency of treatments against ectoparasites in dogs and cats is carried out mostly four times a year or when their presence is detected. Gastrointestinal parasites are poorly known, and scabies is the most mentioned disease. Most owners of dogs (85.6%) and cats (93%) are unaware of the meaning of zoonosis and that their pets can transmit diseases to them, suggesting its low impact on health management in pets. Macrocyclic l...

The present article aims to report a clinical case that exposes the guided bone regeneration treatment (ROG) in a tooth with a traumatic fracture. The procedure consisted of bone regeneration, which has proven to be a successful technique to promote the recovery of dentoalveolar bone defects. Lyophilized organic bovine bone and resorbable bovine collagen membrane were placed one month after having suffered a dentoalveolar trauma at the level of the upper right central incisor. In conclusion, the treatment proved to be very effective in increasing and preserving the dimensions of the resorbed alveolar ridges, optimizing the biological conditions of our patients for subsequent rehabilitation.  

He has visited 20 villages located along the valley Sihuas province of Arequipa, Arequipa . Was conducted epidemiological study in 180 homes , having covered nuestrta survey of 998 people. The study of housing states: overcrowded population , as the average between people and beds is 2.17. The general type of housing is quite poor ; in almost all households ( 96.11 %) pets, preferably poultry ( 92.22 %) and guinea pigs ( 83.33 %) are raised. Vector alone has been found Triantoma infestans visited 106 of housing 180 ( 58.88 % ) , of which 57 (31.6 % ) the trianomas were infected with Trypanosoma cruzi . 936 reduviid bugs have been examined , having determined a - triatomine Trypanosoma 34.09 % , being the partial data rate as follows: 25.05 % is the rate of infection from tritomas bedroom, out of a total of 427 copies; and 46.80 %, is the corresponding index in cuyeros of a total of 250 e...

Between 2000 and 2016 we carried out 15 rapid biological inventories in remote areas of the Andean foothills and Amazon basin in Peru. During these inventories, 27 botanists collected 9397 fertile vascular plant specimens. By the end of 2017, more than half of these specimens had been identified to species. Of the 2303 species identified to date, 64 species and 2 genera (Dicorynia and Monopteryx) are new records for the flora of Peru. If this rate of discovery proves typical, the number of new records for Peru in the rapid inventory material could increase, which indicates that there is still much to discover in the Peruvian flora.
