1. Qual é o perfil de resistência antimicrobiana ambulatorial às fluoroquinolonas em casos de cistite não complicada causada por Escherichia coli no Brasil?
Há carência de estudos de qualidade aplicáveis à Atenção Primária à Saúde sobre o tema no Brasil. Os principais estudos utilizam amostras de urina de pacientes atendidos em serviços de média e alta complexidade, o que pode introduzir importantes vieses no trabalho, prejudicando o grau de generalização dos resultados para os pacientes atendido

2. Evaluation of different protocols for culturing mesenchymal stem cells derived from murine bone marrow
ABSTRACT Introduction: Culturing bone marrow mesenchymal stem cells (BM-MSCs) is a key point in different fields of research, including tissue engineering and regenerative medicine and studies of the bone marrow microenvironment. However, isolating and expanding murine BM-MSCs in vitro has challenged researchers due to the low purity and yield of obtained c

3. Determination of in-vitro phenolics, antioxidant capacity and bio-accessibility of Kombucha tea produced from black carrot varieties grown in Turkey
Abstract Black carrot, which is an economically important product, is produced extensively in Konya and Hatay regions in Turkey. Kombucha tea is a symbiotic system, comprises of bacteria and yeasts cultures called as SCOBY, and produced by fermentation of sugar and tea leaves. Kombucha samples contained black carrot juice in two concentrations (10 and 20%) a

4. In Vitro Homeostasis of Rat Oral Epithelial Cell Cultures Following Withdrawal of Periodontal Pathogens
Resumo A inflamação dos tecidos periodontais é a consequência da interação entre patógenos periodontais e o sistema imunológico. Isso está associado ao aumento da expressão de citocinas inflamatórias, que podem exercer efeito destrutivo nos tecidos periodontais quando liberadas por um longo período. O objetivo deste estudo foi rastrear cronologic

5. Standardization of organoid culture for evaluation of melanogenesis induced by UVB, UVA and visible light,
Abstract Background: Organoid cultures are primary cultures that maintain architectural characteristics and the relationships between cells, as well as the extracellular matrix. They are alternatives for pathophysiological or therapeutic investigation rather than animal and in vitro tests. Objective: Development of a cutaneous organoid culture model, aimin

6. Growth and Differentiation Factor-9 Supplementation Affects Viability and Morphology of Preantral Follicles in Equine Ovarian Fragments During Short-term in vitro Culture
Abstract This study aimed to evaluate different concentrations of growth and differentiation factor-9 (GDF-9) on the development and maintenance of equine preantral follicle morphology during short-term in vitro culture. Ovaries (n=5) from five mares were collected from a local slaughterhouse and transported to the laboratory, where nine fragments (5x5x1mm)

7. Generation of Yellow Fever virus vaccine in skeletal muscle cells of chicken embryos
BACKGROUND The Yellow Fever (YF) vaccine is produced by the inoculation of embryonated chicken eggs with YF17DD virus on the ninth day of development. Full embryos are collected on the twelfth day of development for vaccine formulation. Skeletal muscle tissue is the main site where biosynthesis of viral particles occurs. OBJECTIVES This study aimed to an

9. Obtaining monokaryotic and dikaryotic mycelial cultures of two Amazonian strains of Geastrum (Geastraceae, Basidiomycota)
RESUMO A alta diversidade do gênero Geastrum e a dificuldade de obtenção de culturas miceliais prejudicam o estudo ecofisiológico e a exploração do potencial biotecnológico do táxon. Nesse estudo, foram testados diferentes meios de cultivo, visando a obtenção de culturas miceliais para G. lloydianum e G. subiculosum coletadas na Amazônia brasileir

10. Comparison of Volatile Profile and Antioxidant Activity of Piper divaricatum G. Meyer (Piperaceae) Using Cuttings and Cell Tissue
In this study, P. divaricatum (Piperaceae) plants were subcultured by cuttings and cell tissue in order to carry out a comparison of the volatile profile, phenolic compounds, and antioxidant activity. Propagation by cuttings used vermiculite substrate and Murashige-Skoog (MS) medium in the absence of growth regulators and rooting started at 15 days of growth

11. Effects of Light Quality and Chemical Elicitors on the Growth Parameters and Rosmarinic Acid Content of in vitro Cultures of Hyptis pectinata (L.) Poit.
Hyptis pectinata (L.) Poit is a folk medicinal species in Northeast Brazil. In this work, seedlings of H. pectinata were cultured in vitro under diverse light quality spectra and under the influence of two distinct chemical elicitors, salicylic acid and silver nitrate (SN), at concentrations of 30 and 60 μM. Growth parameters, biomass and rosmarinic acid (R
