RESUMO
Silk is a natural composite fiber composed mainly of hydrophobic fibroin and hydrophilic sericin, produced by the silkworm Bombyx mori. In the textile industry, the cocoons of B. mori are processed into silk fabric, where the sericin is substantially removed and usually discarded in wastewater. This wastewater pollutes the environment and water sources. However, sericin has been recognized as a potential biomaterial due to its biocompatibility, immunocompatibility, biodegradability, anti-inflammatory, antibacterial, antioxidant and photoprotective properties. Moreover, sericin can produce hydrogels, films, sponges, foams, dressings, particles, fibers, etc., for various biomedical and pharmaceutical applications (e.g., tissue engineering, wound healing, drug delivery, cosmetics). Given the severe environmental pollution caused by the disposal of sericin and its beneficial properties, there has been growing interest in upcycling this biomaterial, which could have a strong and positive economic, social and environmental impact.
RESUMO
The genome of Corynebacterium pseudotuberculosis MB20 bv. equi was sequenced using the Ion Personal Genome Machine (PGM) platform, and showed a size of 2,363,089 bp, with 2,365 coding sequences and a GC content of 52.1%. These results will serve as a basis for further studies on the pathogenicity of C. pseudotuberculosis bv. equi.
RESUMO
In this work, perturbed angular correlation (PAC) spectroscopy is used to study differences in the nuclear quadrupole interactions of Cd probes in DNA molecules of mice infected with the Y-strain of Trypanosoma cruzi. The possibility of investigating the local genetic alterations in DNA, which occur along generations of mice infected with T. cruzi, using hyperfine interactions obtained from PAC measurements and density functional theory (DFT) calculations in DNA bases is discussed. A comparison of DFT calculations with PAC measurements could determine the type of Cd coordination in the studied molecules. To the best of our knowledge, this is the first attempt to use DFT calculations and PAC measurements to investigate the local environment of Cd ions bound to DNA bases in mice infected with Chagas disease. The obtained results also allowed the detection of local changes occurring in the DNA molecules of different generations of mice infected with T. cruzi, opening the possibility of using this technique as a complementary tool in the characterization of complicated biological systems.

Neste estudo procuramos determinar a satisfação e a percepção de mudanças específicas resultantes da participação num programa de treino metacognitivo e da cognição social (TMSC) para pessoas com Esquizofrenia. Participaram 21 participantes com diagnóstico de Esquizofrenia responderam a um inquérito por questionário de administração direta com questões abertas, realizado a meio e no final do TMCS. A partir das categorias (1) Satisfação com o programa, (2) Reestruturação sócio-cognitiva e (3) Mudanças na relação eu-outro, verificamos que o programa é relevante, tem potencial para introduzir mudanças na relação com os outros e parece otimizar a cognição social. Os aspectos negativos apontados estão relacionados com a duração do programa e das sessões, e com a linguagem utilizada...
This study aimed to understand the satisfaction and the perception of specific changes triggered by the participation in a metacognitive and social cognition training program (MSCT) for people with Schizophrenia. Participed 21 participants with a diagnosis of Schizophrenia answered a questionnaire of direct-response with open ended questions applied in the middle-term and at the end of the MSCT. Based on the categories (1) satisfaction with the program, (2) social cognitive restructuring and (3) Changes in the self-other relationship, we found that the program was considered to be relevant, had the potential to improve relationships with others and facilitated the enhancement of social cognition. The most important negative aspects mentioned were the duration of the program and sessions, and the specific language used...
