Lactate-upregulation of lactate oxidation complex-related genes is blunted in left ventricle of myocardial infarcted rats

Braz. j. med. biol. res; 51 (11), 2018
Lactate modulates the expression of lactate oxidation complex (LOC)-related genes and cardiac blood flow under physiological conditions, but its modulatory role remains to be elucidated regarding pathological cardiac stress. The present study evaluated the effect of lactate on LOC-related genes expressio...

Immediate laser-induced hemostasis in anticoagulated rats subjected to oral soft tissue surgery: a double-blind study

Abstract Given the growing trend towards medical indications for continuous use of anticoagulants, the number of patients on these medications continues to rise. The management of patients on oral anticoagulants requiring oral surgical procedures has aroused much controversy. Changes in an anticoagulatio...

Analysis of the muscle tissue of Wistar rats submitted to the sciatic nerve compression model and cryotherapy

Einstein (Säo Paulo); 16 (3), 2018
ABSTRACT Objective: To evaluate the effects of right sciatic nerve compression and cryotherapy on muscle tissue. Methods: We used 42 male Wistar rats, subdivided in the following Groups Control, Injury 3, Injury 8 and Injury 15 submitted to nerve compression and euthanized in the 3rd, 8th and 15th day ...

Physical training reverses changes in hepatic mitochondrial diameter of Alloxan-induced diabetic rats

Einstein (Säo Paulo); 16 (3), 2018
ABSTRACT Objective To investigate the effects of physical training on metabolic and morphological parameters of diabetic rats. Methods Wistar rats were randomized into four groups: sedentary control, trained control, sedentary diabetic and trained diabetic. Diabetes mellitus was induced by Alloxan (3...

Prophylactic application of laser light restores L-FABP expression in the livers of rats submitted to partial ischemia

Clinics; 73 (), 2018
OBJECTIVES: The objective of the present study was to evaluate the protective effect of pre-conditioning treatment with laser light on hepatic injury in rats submitted to partial ischemia using mitochondrial function and liver fatty acid binding protein as markers. METHODS: Rats were divided into four g...

Behavioral cross-sensitization between testosterone and fenproporex in adolescent and adult rats

Braz. j. med. biol. res; 51 (1), 2018
The abuse of psychoactive drugs is considered a global health problem. During the last years, a relevant number of studies have investigated the relationship between anabolic-androgenic steroids (AAS) and other psychoactive drugs. AAS, such as testosterone, can cause a dependence syndrome that shares man...

Endothelin-1 receptor antagonists protect the kidney against the nephrotoxicity induced by cyclosporine-A in normotensive and hypertensive rats

Braz. j. med. biol. res; 51 (2), 2018
Cyclosporin-A (CsA) is an immunosuppressant associated with acute kidney injury and chronic kidney disease. Nephrotoxicity associated with CsA involves the increase in afferent and efferent arteriole resistance, decreased renal blood flow (RBF) and glomerular filtration. The aim of this study was to eval...

Granulocyte colony-stimulating factor combined with Methylprednisolone improves functional outcomes in rats with experimental acute spinal cord injury

Clinics; 73 (), 2018
OBJECTIVES: To evaluate the effects of combined treatment with granulocyte colony-stimulating factor (G-CSF) and methylprednisolone in rats subjected to experimental spinal cord injury. METHODS: Forty Wistar rats received a moderate spinal cord injury and were divided into four groups: control (no treat...

Neuroprotective effects of erythropoietin on rat retinas subjected to oligemia

Clinics; 73 (), 2018
OBJECTIVES: Erythropoietin may have neuroprotective potential after ischemia of the central nervous system. Here, we conducted a study to characterize the protective effects of erythropoietin on retinal ganglion cells and gliotic reactions in an experimentally induced oligemia model. METHODS: Rats were ...

Evaluation of photobiomodulation therapy associated with guided bone regeneration in critical size defects. In vivo study

J. appl. oral sci; 26 (), 2018
Abstract The repair of bone defects raises the interest of investigators in several health specialties. Grafting techniques with bone substitutes and laser therapies have been investigated to replace autogenous bone and accelerate the bone healing process. Objective To evaluate the effect of photobiomod...
