Keratoconus progression is not inhibited by reducing eyelid muscular force with botulinum toxin A treatment: a randomized trial

Arq. bras. oftalmol; 80 (2), 2017
ABSTRACT Purpose: To evaluate whether reducing eyelid muscular force through the administration of botulinum toxin type A (BTX-A) to the orbicularis oculi muscles of patients with keratoconus affected corneal parameters indicative of disease progression. Methods: In this prospective parallel randomized...

Cytotoxicity Evaluation of Root Canal Sealers Using an In Vitro Experimental Model with Roots

Braz. dent. j; 28 (2), 2017
Abstract The aim of the present study was to evaluate the cytotoxicity of root canal sealers under conditions closely resembling a clinical reality. A primary human fibroblast cell line was seeded in 24-well acrylic plates with Dulbecco’s modified Eagle’s medium supplemented with 10% serum fe...

Comparison of Two Central Venous Pressure Control Strategies to Prevent Atrial Fibrillation After Coronary Artery Bypass Grafting

Arq. bras. cardiol; 108 (4), 2017
Abstract Background: Atrial fibrillation (AF) takes place in 10-40% of patients undergoing coronary artery bypass grafting (CABG), and increases cardiovascular mortality. Enlargement of atrial chambers is associated with increased AF incidence, so patients with higher central venous pressure (CVP) are e...

Effects of Continuous and Accumulated Exercise on Endothelial Function in Rat Aorta

Arq. bras. cardiol; 108 (4), 2017
Abstract Background: The practice of exercise in short bouts repeated throughout the day may be an alternative strategy to lift people out of physical inactivity. Objective: to evaluate if accumulated exercise, as occurs in continuous exercise training, improve endothelial function in rat aorta. Metho...

Attention-deficit/hyperactivity disorder: the impact of methylphenidate on working memory, inhibition capacity and mental flexibility

Arq. neuropsiquiatr; 75 (4), 2017
ABSTRACT Objective To compare children with attention-deficit/hyperactivity disorder (ADHD), before and after the use of methylphenidate, and a control group, using tests of working memory, inhibition capacity and mental flexibility. Methods Neuropsychological tests were administrated to 53 boys, 9&#...

Effects of ozone therapy on facial nerve regeneration

Abstract Introduction: Ozone may promote moderate oxidative stress, which increases antioxidant endogenous systems. There are a number of antioxidants that have been investigated therapeutically for improving peripheral nerve regeneration. However, no previous studies have reported the effect of ozone t...

Surveillance of bacteria Pseudomonas aeruginosa and MRSA associated with chronic suppurative otitis media

Abstract Introduction: Suppurative otitis media is a critical disease causing perforation of the tympanic membrane associated with changes of the mucoperiosteum of the middle ear cleft. Objective: To isolate causative bacteria from chronic suppurative ear discharges and to ascertain their antibiotic pr...

Specific immediate early gene expression induced by high doses of salicylate in the cochlear nucleus and inferior colliculus of the rat

Abstract Introduction: Salicylate at high doses induces tinnitus in humans and experimental animals. However, the mechanisms and loci of action of salicylate in inducing tinnitus are still not well known. The expression of Immediate Early Genes (IEG) is traditionally associated with long-term neuronal m...

Effect of tadalafil 5mg daily treatment on the ejaculatory times, lower urinary tract symptoms and erectile function in patients with erectile dysfunction

ABSTRACT Objective To investigate the effect of a 5mg daily tadalafil treatment on the ejaculation time, erectile function and lower urinary tract symptoms (LUTS) in patients with erectile dysfunction. Materials and Methods A total of 60 patients diagnosed with erectile dysfunction were retrospective...

Effects of nitric oxide inhibitors in mice with bladder outlet obstruction

Int. braz. j. urol; 43 (2), 2017
ABSTRACT Purpose To investigate the lower urinary tract changes in mice treated with L-NAME, a non-selective competitive inhibitor of nitric oxide synthase (NOS), or aminoguanidine, a competitive inhibitor of inducible nitric oxide synthase (iNOS), after 5 weeks of partial bladder outlet obstruction (B...
