The association of vitamin D levels and the frailty phenotype among non-geriatric dialysis patients: a cross-sectional study

Clinics; 73 (), 2018
OBJECTIVES: The aim of this study was to investigate the frequency of frailty and the association of vitamin D levels and the frailty phenotype among non-geriatric dialysis patients. METHOD: Seventy-four stable, chronic hemodialysis patients from the hemodialysis unit of the hospital were enrolled in th...

MicroRNA-1247 inhibits cell proliferation by directly targeting ZNF346 in childhood neuroblastoma

Biol. Res; 51 (), 2018
BACKGROUND: Neuroblastoma (NB) represents the most common extracranial solid tumor in children. Accumulating evidence shows that microRNAs (miRs) play an important role in the carcinogenesis of NB. Here, we investigated the biological function of miR-1247 in NB in vitro. METHODS/RESULTS: We found miR-12...

Involvement of K+ATP and Ca2+ channels in hydrogen sulfide-suppressed ageing of porcine oocytes

Biol. Res; 51 (), 2018
BACKGROUND: Hydrogen sulfide has been shown to improve the quality of oocytes destined for in vitro fertilization. Although hydrogen sulfide is capable of modulating ion channel activity in somatic cells, the role of hydrogen sulfide in gametes and embryos remains unknown. Our observations confirmed the ...

Ascorbate peroxidase overexpression protects Leishmania braziliensis against trivalent antimony effects

Mem. Inst. Oswaldo Cruz; 113 (12), 2018
Ascorbate peroxidase (APX) is a redox enzyme of the trypanothione pathway that converts hydrogen peroxide (H2O2) into water molecules. In the present study, the APX gene was overexpressed in Leishmania braziliensis to investigate its contribution to the trivalent antimony (SbIII)-resistance phenotype. We...

La microdeleción 16p11.2 se relaciona, habitualmente, con discapacidad intelectual y trastornos del espectro autista. El rango fenotípico incluye un espectro que se extiende desde discapacidad intelectual con o sin autismo, alteraciones del aprendizaje y del lenguaje hasta fenotipos normales. El diagn...

Subcutaneous infection by Graphium basitruncatum in a heart transplant patient

Braz. j. infect. dis; 21 (6), 2017
ABSTRACT Graphium basitruncatum, a synanamorph of Pseudoallescheria has been rarely reported in human infections. We report a case of subcutaneous phaeohyphomycosis caused by this fungus in a heart transplant recipient. We also describe the phenotypic, molecular methods and matrix-assisted laser desorpti...
