Los anestésicos locales en estomatología vienen siendo utilizados desde principios del siglo XX en las diversas disciplinas de la odontología, demostrando gran efectividad. Los anestésicos locales se definen como la pérdida de sensibilidad temporal sin ocasionar pérdida de conciencia lo que la diferencia de la anestesia general. Entender los mecanismos del funcionamiento de la conducción nerviosa es de suma importancia para la comprensión del modo en el que estos fármacos actúan y modifican de manera reversible la función nerviosa; nace de este modo diversas teorías y/o postulados para explicar la manera de funcionamiento de los anestésicos locales y una de las teorías con más seguidores es la de los receptores específicos. Los anestésicos locales poseen una estructura química compleja que le confiere a estos ciertas características como el lugar donde se va llevar a c...

Parasitism in Didelphis sp. can express different physiological impacts resulting from the parasite load, as well as the affected organ. It is therefore pertinent to identify the sites and locations of infection to understand the possible effects on the host. The present work is a systematic literature review study on articles that described the presence of parasites and their respective sites of infection. Of the 114 studies retrieved in the literature, 54 were eligible to be included in this review. Based on the studies analyzed, the sites identified were organs and/or regions that include the: heart, mesenteric arteries, brain/cerebrum, oral mucosa, esophagus, stomach, small/large intestine, liver, gallbladder, lungs, bronchi, and bronchioles, in addition to other structures and regions. In terms of impact on the host, the analyzed infection sites suggest significant functional impair...

Autism Spectrum Disorder (ASD) is considered a neurodevelopmental disorder, whose prevalence has increased in recent years, showing in some cases deficits in the cognitive area, with processing speed (PS) being one of the affected variables. Therefore, the present study aims to: 1) compare the scores obtained in relation to the PS variable between students aged 6 to 11 with ASD and their peers with neurotypical development in Metropolitan Lima; and 2) establish the PS profile of the included students with ASD. For this, 30 children aged 6 to 11 attending to regular basic education institutions (RBE) in Metropolitan Lima were sampled, 15 with neurotypical development and 15 included with ASD. For the first objective, a case-control design (CCD) was used, while the second objective was a selective non-probabilistic cross-sectional design. Results showed a lower performance by the group wit...

This paper presents the results of a non-experimental cross-sectional study conducted under a mixed explanatory design (with manifest and latent variables), in an indigenous school in a rural area and an urban school in Morelos (Mexico). The sociodemographic context of the schools of origin was considered as a predictor variable of Mathematics achievement in 6th grade of primary school, and the educational level of the parents and family support were considered as mediating variables. At the end of 6th grade, students from both schools answered a scale on family support and a short test on two mathematical competencies: Communicating mathematical information and Using techniques efficiently. The data were analyzed with two structural regression models of relationships between manifest variables (school context and parents' educational level) and latent variables (family support with eigh...
