Reaction mechanisms of flavins and flavoproteins from an electronic-structure perspective

Proteins equipped with flavin adenine dinucleotides (FAD) or flavin mononucleotides (FMN) are named flavoproteins and constitute about 1% of all existing proteins. They catalyze redox, acid-base and photochemical reactions in a variety of biochemical phenomena that goes from energy metabolism to DNA repa...

Identificação de alterações bioquímicas em células epiteliais bronquiais humanas normais expostas a fumarato

A reprogramação metabólica de células do câncer é apontada como uma característica essencial para o desenvolvimento da doença (cancer hallmark). Estudos mostram que mutações na enzima fumarato hidratase levam ao aumento da concentração intra e extracelular de fumarato, o que ocorre paralelame...

Aliskiren attenuates cardiac dysfunction by modulation of the mTOR and apoptosis pathways

Braz. j. med. biol. res; 53 (2), 2020
Aliskiren (ALS) is well known for its antihypertensive properties. However, the potential underlying the molecular mechanism and the anti-hypertrophic effect of ALS have not yet been fully elucidated. The aim of the present study was to investigate the role of ALS in mammalian target of rapamycin (mTOR) ...

Evaluation of growth performance and gastro-intestinal parameters on the response of weaned piglets to dietary organic acids

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Two experiments (E) were carried out to evaluate the effects of fumaric acid and an acidifier blend [composed by calcium formate, calcium lactate and medium-chain fatty acids (capric and caprylic)] in piglet diets containing colistin (40 ppm) or halquinol (120 ppm) on performance, diarrhea incid...

Urinary cytokine profiles according to the site of blockade of the renin-angiotensin system in nephrectomized rats

J. bras. nefrol; 39 (2), 2017
Abstract Introduction: It is still unknown how the pharmacological inhibition of the Renin Angiotensin System (RAS) impacts the levels of inflammation and fibrosis biomarkers. Objective: This study sought to evaluate the effect of enalapril, candesartan and aliskiren on urinary levels of cytokines in a...

A memória hiperglicêmica no rim diabético: marcas metabólicas, moleculares e epigenéticas

A nefropatia diabética (ND) é uma das complicações microvasculares do diabetes e consiste no dano ao parênquima renal por consequência de uma série de fatores hemodinâmicos e moleculares. A ocorrência de ND e de outras complicações mesmo em indivíduos sob adequado controle glicêmico tem sido...

Efecto del aliskireno sobre la angiogénesis en modelo de membrana alantocoriónica (MAC) de pollo

Int. j. morphol; 34 (4), 2016
La acción antiangiogénica de los inhibidores del receptor de angiotensina II (ARA II), ha sido documentada previamente, sin embargo, no ha sido descrita la relación entre angiogénesis e inhibidores directos de la renina (DRIs), los cuales participan regulando el sistema renina-angiotensina-aldosteron...

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 ...

Dosis efecto de la administración de fumarato ferroso en personas ancianas con deficiencia de hierro
Dose effect of ferrous fumarate administration in elderly persons with iron deficiency

Rev. gastroenterol. Méx; 64 (4), 1999
Antecedentes: la anemia es un problema hematológico prevalente en ancianos, que afecta a 14 por ciento de los hombres y a 6 por ciento de las mujeres de la población mayor de 60 años de edad en México. Objetivo: determinar el efecto de la administración prolongada de fumarato ferroso en ancianos con...
