Proton NMR characterization of intact primary and metastatic melanoma cells in 2D & 3D cultures

Biol. Res; 50 (), 2017
OBJECTIVE: To characterize the differences between the primary and metastatic melanoma cell lines grown in 2D cultures and 3D cultures. METHODS: Primary melanoma cells (WM115) and metastatic melanoma cells (WM266) extracted from a single donor was cultured in 2D as well as 3D cultures. These cells were c...

El metabolismo de la glucosa en pacientes con hipertensión arterial

Thiazide diuretics (TD) are recommended as first-line therapy in uncomplicated hypertension by several professional organizations. However, they also may pose a risk of glucose metabolism abnormalities in certain individuals. Early studies showed TD cause a small increase in fasting glucose. These effect...

BACKGROUND: From ancient times, marine algae have emerged as alternative medicine and foods, contains the rich source of natural products like proteins, vitamins, and secondary metabolites, especially Chlorella vulgaris (C. vulgaris) contains numerous anti-inflammatory, antioxidants and wound healing sub...

Renin-angiotensin system blockers regulate the metabolism of isolated fat cells in vitro

Braz. j. med. biol. res; 49 (8), 2016
Due to the presence of the renin-angiotensin system (RAS) in tissues and its specific influence on white adipose tissue, fat cells are possible targets of pharmacological RAS blockers commonly used as anti-hypertensive drugs. In the present study, we investigated the effects of different RAS blockers on ...

Modeling of glutamic acid production by Lactobacillus plantarum MNZ

Electron. j. biotechnol; 16 (4), 2013
Background: L-glutamic acid, the principal excitatory neurotransmitter in the brain and an important intermediate in metabolism acts as a precursor of γ-amino butyric acid (GABA). In the present study, culture condition for enhanced glutamic acid production by Lactobacillus plantarum MNZ was optimiz...

Evaluación del transporte de glucosa, fármacos y del potencial de membrana como métodos pronósticos de quimioterapia en Leishmania spp

El fracaso terapéutico en leishmaniasis a menudo esta asociado a resistencia a los medicamentos por parte de los parásitos. Hasta ahora no se ha evaluado sistemáticamente si este fenotipo compromete u optimiza el metabolismo o la efectividad en leishmania, es decir, su competencia y adaptabilidad. Dur...

Esquema de restriçäo alimentar altera a resposta celular à insulina em ratos diabéticos
Scheme of food restriction change the cellular response to insulin in rats

A resistência à insulina é um elemento chave na gênese de várias alterações fisiopatológicas. O esquema de restrição alimentar meal-feeding (MF) consiste na oferta de uma única refeição diária de 2h, sem, contudo, limitar a quantidade de alimento durante esse período. Este esquema determin...
