Avaliação da interação entre leveduras isoladas de kombucha e bactérias probióticas

Um dos maiores desafios no desenvolvimento de produtos probióticos é entender como os microrganismos interagem entre si e com o hospedeiro. Quando falamos em alimentos fermentados tradicionais, este obstáculo aumenta porque a matriz alimentar já possui um microbioma intrínseco. No entanto, também ...

Crecimiento y supervivencia de Cryphiops caementarius en cocultivo con Oreochromis niloticus a diferentes densidades

Rev. MVZ Córdoba; 26 (2), 2021
RESUMEN Objetivo. Evaluar el crecimiento y la supervivencia de Cryphiops caementarius en cocultivo con Oreochromis niloticus a diferentes densidades. Materiales y métodos. Se utilizaron camarones machos (5.86 cm y 7.65 g) y alevines revertidos de tilapia (5.65 cm y 2.61 g). Se emplearon nueve acuario...

An in vitro model mimicking the complement system to favor directed phagocytosis of unwanted cells

Electron J Biotechnol; 49 (), 2021
BACKGROUND: Opsonization, is the molecular mechanism by which target molecules promote interactions with phagocyte cell surface receptors to remove unwanted cells by induced phagocytosis. We designed an in vitro system to demonstrate that this procedure could be driven to eliminate adipocytes, using pept...

Improved protease activity of Pixian broad bean paste with cocultivation of Aspergillus oryzae QM-6 and Aspergillus niger QH-3

BACKGROUND: The preparation of broad bean koji is a key process in the production of Pixian broad bean paste (PBP). Protease is essential for the degradation of proteins during PBP fermentation. To obtain broad bean koji with high protease activity using the cocultivated strains of Aspergillus oryzae QM-...

A platform to understand amyotrophic lateral sclerosis (ALS) and extend human motor neurons longevity

Int. j. morphol; 37 (4), 2019
In vitro modeling of neurodegenerative diseases is now possible by using patient-derived induced pluripotent stem cells (iPS). Through them, it is nowadays conceivable to obtain human neurons and glia, and study diseases cellular and molecular mechanisms, an attribute that was previously unavailable to a...

The improvement of bioactive secondary metabolites accumulation in Rumex gmelini Turcz through co-culture with endophytic fungi

Braz. j. microbiol; 49 (2), 2018
Abstract Aspergillus sp., Fusarium sp., and Ramularia sp. were endophytic fungi isolated from Rumex gmelini Turcz (RGT), all of these three strains could produce some similar bioactive secondary metabolites of their host. However the ability to produce active components degraded significantly after cultu...

Effect of vegetable by-products on folate production by starter and probiotic microorganisms to develop a bio-enriched fermented soy product

However, folate production was strain-dependent and also dependent on the environmental conditions and on the vegetable substrate used. Passion fruit by-product presented the lowest folate concentration and was selected for the following experiments. Thus, the impact of the supplementation of soymilk wit...

Single-cell qPCR facilitates the optimization of hematopoietic differentiation in hPSCs/OP9 coculture system

Braz. j. med. biol. res; 51 (5), 2018
Human pluripotent stem cells (hPSCs)/OP9 coculture system is a widely used hematopoietic differentiation approach. The limited understanding of this process leads to its low efficiency. Thus, we used single-cell qPCR to reveal the gene expression profiles of individual CD34+ cells from different stages o...

Response of a co-culture model of epithelial cells and gingival fibroblasts to zoledronic acid

Braz. oral res. (Online); 30 (1), 2016
Abstract Osteonecrosis of the jaw is an adverse effect of bisphosphonates. While the etiopathogenesis of this condition has been investigated, the interactions and effects of bisphosphonates on oral mucosa cells remain unclear. It is hypothesized that cell culture models, such as co-culture or three-dime...

Growth hormone in the presence of laminin modulates interaction of human thymic epithelial cells and thymocytes in vitro

Biol. Res; 49 (), 2016
BACKGROUND: Several evidences indicate that hormones and neuropeptides function as immunomodulators. Among these, growth hormone (GH) is known to act on the thymic microenvironment, supporting its role in thymocyte differentiation. The aim of this study was to evaluate the effect of GH on human thymocyte...
