The association between genetic polymorphism of glutathione peroxidase 1 (rs1050450) and keratoconus in a Turkish population

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purpose: To investigate the potential associations between keratoconus and catalase rs1001179, superoxide dismutase 2 rs4880, and glutathione peroxidase 1 rs1050450 gene polymorphisms in a Turkish population. Methods: The study group included 121 unrelated keratoconus patients and 94 unrelate...

Whole-exome sequencing in familial keratoconus: the challenges of a genetically complex disorder

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purpose: The underlying genetic causes of keratoconus are essentially unknown. Here, we conducted whole-exome sequencing in 2 Brazilian families with keratoconus. Methods: Whole-exome sequencing was performed on 6 keratoconus-affected individuals of 2 unrelated pedigrees from Southern Brazil. ...

Refractive and visual outcomes after Ferrara corneal ring segment implantation at a 60% depth in keratoconic eyes: case series

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purpose: This report addresses refractive, topographic, visual acuity, and optical coherence tomography outcomes 12 months after femtosecond, laser-assisted insertion of Ferrara intrastromal corneal ring segments in keratoconic eyes at a depth of 60%. Methods: Interventional, prospective, non-...

Factors associated with vision-related quality of life in Brazilian patients with glaucoma

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purpose: To evaluate the impact of visual acuity, visual field damage, and other factors on the quality of life in Brazilian patients with glaucoma. Methods: This cross-sectional prospective study involved 49 patients with glaucoma enrolled based on the presence of reproducible standard automa...

A three-dimensional printed photopolymer resin implant for orbital rehabilitation for evisceration

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purpose: To evaluate the biocompatibility of three-dimensional (3D) printed orbital spheres for evisceration. Materials: A total of 10 consecutive patients (eight females and two males; mean age, 46.8 ± 14.2 years) underwent evisceration of blind painful eyes. 3D spherical implants produced b...

Biochanin A attenuates myocardial ischemia/reperfusion injury through the TLR4/NF-κB/NLRP3 signaling pathway

Acta cir. bras; 34 (11), 2019
Abstract Purpose: Myocardial ischemia/reperfusion (Ml/R) injury is a leading cause of damage in cardiac tissues, with high rates of mortality and disability. Biochanin A (BCA) is a main constituent of Trifolium pratense L. This study was intended to explore the effect of BCA on Ml/R injury and explore t...

Effect of norbixin-based poly(hydroxybutyrate) membranes on the tendon repair process after tenotomy in rats

Acta cir. bras; 34 (11), 2019
Abstract Purpose: To determine the efficacy of norbixin-based poly(hydroxybutyrate) (PHB) membranes for Achilles tendon repair. Methods: Thirty rats were submitted to total tenotomy surgery of the right Achilles tendon and divided into two groups (control and membrane; n = 15 each), which were further ...

GDF11 ameliorated myocardial ischemia reperfusion injury by antioxidant stress and up-regulating autophagy in STZ-induced type 1 diabetic rats

Acta cir. bras; 34 (11), 2019
Abstract Purpose: To investigate whether GDF11 ameliorates myocardial ischemia reperfusion (MIR) injury in diabetic rats and explore the underlying mechanisms. Methods: Diabetic and non-diabetic rats subjected to MIR (30 min of coronary artery occlusion followed by 120 min of reperfusion) with/without ...

Laboratory investigations in the diagnosis and follow-up of GH-related disorders

ABSTRACT In addition to auxiological, clinical and metabolic features measurements of growth hormone (GH) and insulin-like growth factor I (IGF-I) complement our tools in diagnosis and follow-up of GH-related disorders. While comparably robust during the pre-analytical phase, measurement and interpretati...

Evaluación de la sensibilidad de cepas de Pseudomonas aeruginosa multi-resistentes frente a ceftolozano/tazobactam

Rev. chil. infectol; 36 (5), 2019
Resumen Introducción: Pseudomonas aeruginosa es un patógeno oportunista asociado a alta morbi-mortalidad. Para cepas multi-resistentes (MDR), ceftolozano/tazobactam (CTZ) se ha autorizado por la Agencia Europea del Medicamento (EMA) para infecciones del tracto urinario complicadas, pielonefritis aguda...
