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. Expansion of cord blood stem cells in fibronectin-coated microfluidic bioreactor
ABSTRACT Background: Hematopoietic stem/progenitor cell transplantation is the main treatment option for hematological malignancies and disorders. One strategy to solve the problem of low stem cell doses used in transplantation is pre-transplant expansion. We hypothesized that using fibronectin-coated microfluidic channels would expand HSPCs and keep self-r

4. Synthesis of 1,2,3-Triazole Derivatives of Hydnocarpic Acid Isolated from Carpotroche brasiliensis Seed Oil and Evaluation of Antiproliferative Activity
Carpotroche brasiliensis is a tree native to Brazil, belonging to the family Flacurtiaceae, whose seeds contain a group of cyclopentenyl fatty acids: gorlic (12%), chaulmugric (27%), and hydnocarpic (48.7%). These compounds are considered the main therapeutic agents in the treatment of leprosy. In the present study, a series of novel triazole compounds were

5. Phylogenetic placement of Tritirachium strains from the URM culture collection originally founded by Augusto Chaves Batista (1916-1967) in Brazil, and the description of T. batistae sp. nov.
ABSTRACT Twenty-seven Tritirachium strains were present in the URM culture collection originally founded in Brazil by Augusto Chaves Batista. Fifteen freshly-prepared cultures were obtained from these original strains preserved under mineral oil. DNA was extracted for analysing phylogenetic relationships using the sequence information available from Tritirac

6. 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

7. Impact of calcium aluminate cement with additives on dental pulp-derived cells
Abstract Calcium aluminate cement (CAC) has been highlighted as a promising alternative for endodontic use aiming at periapical tissue repair. However, its effects on dental pulp cells have been poorly explored. Objective: This study assessed the impact of calcium chloride (CaCl2) and bismuth oxide (Bi2O3) or zinc oxide (ZnO) additives on odontoblast cell re

8. Reparative Dentin Formation Using Stem Cell Therapy versus Calcium Hydroxide in Direct Pulp Capping: An Animal Study
Resumo O processo de capeamento pulpar direto é um método terapêutico que visa a manutenção da vitalidade e saúde da polpa, usando um material biocompatível colocado diretamente sobre a polpa exposta. O objetivo deste estudo foi avaliar e comparar o efeito do capeamento pulpar direto usando células-tronco da polpa dentária (CTPDs) ou hidróxido de c

9. Lytic bacteriophages as a potential alternative to control Staphylococcus aureus
Resumo: O objetivo deste trabalho foi caracterizar bacteriófagos autóctones e determinar sua atividade lítica em Staphylococcus aureus. Seis fagos foram isolados de água de lavagem de pisos de estábulos por meio do enriquecimento de cultura com três estirpes de S. aureus. Todos os fagos foram caracterizados pela digestão do DNA com enzimas de restriç

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

12. Cytotoxic effects of Pseudocerastes persicus venom and its HPLC fractions on lung cancer cells
ABSTRACT Background: Several studies have pointed out that certain snake venoms contain compounds presenting cytotoxic activities that selectively interfere with cancer cell metabolism. In this study, Pseudocerastes persicus venom and its fractions were investigated for their anticancer potential on lung cancer cells. Methods: Lung cancer cells (A549) and
