Effect of intravitreal anti-VEGF on choroidal thickness in patients with diabetic macular edema using spectral domain OCT

Arq. bras. oftalmol; 79 (3), 2016
ABSTRACT Purpose: To evaluate choroidal thickness (CT) using spectral domain optical coherence tomography (SD-OCT) imaging at baseline and 6 months after intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment in patients with diabetic macular edema (DME). Methods: A retrospective ch...

Evaluation of sciatic nerve damage following intraneural injection of bupivacaine, levobupivacaine and lidocaine in rats

Rev. bras. anestesiol; 66 (3), 2016
ABSTRACT OBJECTIVE: The local anesthetics may cause neurotoxicity. We aimed to compare the neurotoxic potential of different local anesthetics, local anesthetic induced nerve damage and pathological changes of a peripheral nerve. METHODS: Sixty Wistar rats weighing 200-350 g were studied. Rats were a...

A comparative study between propofol and etomidate in patients under general anesthesia

Rev. bras. anestesiol; 66 (3), 2016
ABSTRACT BACKGROUND AND OBJECTIVES: Induction of anesthesia is a critical part of anesthesia practice. Sudden hypotension, arrhythmias, and cardiovascular collapse are threatening complications following injection of induction agent in hemodynamically unstable patients. It is desirable to use a safe ag...

Use of tranexamic acid in primary total knee replacement: effects on perioperative blood loss

Rev. bras. anestesiol; 66 (3), 2016
ABSTRACT BACKGROUND AND OBJECTIVES: The use of tranexamic acid in primary total knee replacement surgeries has been the subject of constant study. The strategies to reduce bleeding are aimed at reducing the need for blood transfusion due to the risks involved. In this study we evaluated the use of tran...

Methylene blue to treat protamine-induced anaphylaxis reactions. An experimental study in pigs

ABSTRACT Objective: To examine if methylene blue (MB) can counteract or prevent protamine (P) cardiovascular effects. Methods: The protocol included five heparinized pig groups: Group Sham -without any drug; Group MB - MB 3 mg/kg infusion; Group P - protamine; Group P/MB - MB after protamine; Group MB/...

The Labdane Ent-3-Acetoxy-Labda-8(17), 13-Dien-15-Oic Decreases Blood Pressure In Hypertensive Rats

Arq. bras. cardiol; 106 (6), 2016
Abstract Background: Labdane-type diterpenes induce lower blood pressure via relaxation of vascular smooth muscle; however, there are no studies describing the effects of labdanes in hypertensive rats. Objective: The present study was designed to investigate the cardiovascular actions of the labdane-ty...

Molecular detection of clarithromycin and fluoroquinolones resistance in helicobacter pylori infection, directly applied to gastric biopsies, in an urban brazilian population

Arq. gastroenterol; 53 (2), 2016
ABSTRACT Background - Antimicrobial resistance is the major factor leading to eradication failure in H. pylori treatment. Molecular tests are useful to detect genetic mutations predictive of clarithromycin and fluoroquinolones resistance. Knowledge of the local prevalence rate of resistance is importa...

Ursolic acid attenuates beta-amyloid-induced memory impairment in mice

Arq. neuropsiquiatr; 74 (6), 2016
ABSTRACT Objective Increasing evidence demonstrates that oxidative stress and inflammatory are involved in amyloid β (Aβ)-induced memory impairments. Ursolic acid (UA), a triterpenoid compound, has potent anti-inflammatory and antioxidant activities. However, it remains unclear whether UA atte...

Phenotypic and molecular characterization of resistance to macrolides, lincosamides and type B streptogramin of clinical isolates of Staphylococcus spp. of a university hospital in Recife, Pernambuco, Brazil

Braz. j. infect. dis; 20 (3), 2016
Abstract Introduction There is a mechanism of macrolide resistance in Staphylococcus spp. which also affects the lincosamides and type B streptogramins characterizing the so-called MLSB resistance, whose expression can be constitutive (cMLSB) or inducible (iMLSB) and is encoded mainly by ermA and ermC g...
