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...

In-the-bag toric intraocular lens implantation in the case of an anterior capsule tear: a case series

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purpose: To analyze the outcomes of in-the-­bag toric intraocular lens implantation for anterior capsular tears during phacoemulsification. Methods: The cohort of this re­trospective, consecutive, interventional case series included eight patients. One patient was excluded as the tear was us...

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...

Characterization of the intestinal graft in a swine hypotensive after brain death model

Acta cir. bras; 34 (11), 2019
Abstract Purpose: To establish a hypotensive brain death pig model and observe the effects of hypotension on small bowel donors. Methods: The hypotensive brain death model was produced using the modified intracranial water sac inflation method in ten domestic crossbred pigs. Effects of hypotensive brai...

Assessment of remnant liver function and volume after selective ligation of portal vein and hepatic artery in a rat model

Acta cir. bras; 34 (11), 2019
Abstract Purpose: To evaluate liver regeneration after selective ligation of portal vein and hepatic artery by 3D Computed Tomography in an experimental model. Methods: Sixteen Wistar rats were randomized into four equal groups: Group I- control (sham), Group II- isolated selective ligation of the hepa...

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 ...

Bronchodilator test in extreme old age: Adverse effects of short-acting beta-2 adrenergic agonists with clinical repercussion and bronchodilator response

SUMMARY OBJECTIVE: To evaluate chronological age as a limiting factor to perform the bronchodilator test, determine significant adverse effects of short-acting beta 2 agonists with clinical repercussions, and assess bronchodilator response in extreme-old-age patients who undergo the spirometry test. ME...

Objetivo: Obtener una herramienta de computación que promueva el aprendiza...

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...
