Evaluation of remote teaching in master programs in the Oral Pathology and Oral Medicine during the COVID-19 pandemic. Brazilian multicentric study.

BACKGROUND: With the COVID-19 pandemic, there was a need to adopt online teaching methods in a generalized and sudden way, a situation that led to unprecedented changes in the routine of post-graduate students and research development. This study aimed to analyze the evaluation of remote teaching by graduates of master's degrees and advisors in master's programs in the Oral Pathology and Oral Medicine who needed to adapt to a remote teaching methodology in the pandemic. MATERIAL AND METHODS: This quantitative study evaluated the remote teaching in the perception of master's graduates and advisors from postgraduate programs in Oral Pathology and Oral Medicine. Data were collected through an online Google forms® questionnaire. RESULTS: Participated in the study 14 master graduates and 14 master's advisors. Master graduates evaluated that the professors had a good performance (p=0.001), that the duration of the classes was adequate (p=0.015), that the interaction with professors was satisfactory (p=0.007), that they had good interaction with the advisor (p=0.001), that they were satisfied with the remote guidance process (p=0.038) and that face-to-face practical activities were missed (p=0.002). Master's advisors reported satisfaction with remote teaching, good adaptation (p=0.018) and motivation for remote teaching (p=0.016), they evaluated that students were cooperative in activities (p=0.019) and that face-to-face practical activities were missed (p=0.002). CONCLUSIONS: Despite the difficulties, remote teaching proved to be an effective alternative to face-to-face teaching.

Transferability and characterization of microssatellite loci in Anacardium humile A. St. Hil. (Anacardiaceae).

Microsatellite markers were transferred from the cashew, Anarcadium occidentale, to Anacardium humile (Anacardiaceae), a Neotropical shrub from the Brazilian savanna, that produces an edible nut and pseudo-fruit. We tested 14 microsatellite primers from A. occidentale on A. humile. Polymorphism of each microsatellite locus was analyzed based on 58 individuals from three populations. Twelve loci amplified successfully and presented 2 to 9 alleles; expected heterozygosity ranged from 0.056 to 0.869. These 12 microsatellite loci provide a new tool for the generation of fundamental population genetic data for devising conservation strategies for A. humile.

Backcross assisted by microsatellite markers in common bean.

The objectives of the present study were to monitor the effect of backcrossing through microsatellite markers and to compare different marker assisted selection strategies. Four populations were developed using donor parents resistant to the bean golden mosaic virus and, for all crosses, only individuals resistant to the bean golden mosaic virus were backcrossed. For crosses ARC100-4 x DOR303 and ARC100-4 x PHAS8328, assisted selection was carried out in the F(2) and F(2)BC(1) generations, while in the remaining crosses selection was performed only in the F(2)BC(1) generation. For the microsatellite analysis, in each generation, 20 markers were genotyped. The molecular data were analyzed using the NTSys program and the proportion of the recurrent genome introgressed was estimated, based on genotypical configuration of the segregant populations compared to the recurrent parents. The results indicate a higher efficiency in recovering the genotype of the elite genitor through the strategy of backcross assisted selection in the successive generations, and demonstrate a practical and useful application of molecular marker technology associated with bean breeding, to reduce the number of backcrosses and the time to recover the genome of the recurrent genitors.

Farmacodermia em um cão após administração de antibióticos do grupo betalactâmico: relato de caso / Pharmacodermia in a dog after administration of beta-lactam antibiotics: case report

A severe cutaneous reaction in a female dog after administration of penicillin and cephalexin is described, in which the main signs presented by the patient were fever, lack of appetite, and detachment of epidermis in the dorsal region of body.The established treatment was surgical debridement of the region, topical application of Aloe Vera with sugar, and systemic antibiotic therapy with ciprofloxacin, resulting in the recovery and wound closure in approximately 45 days.
