Evaluation of the effect of topical and systemic ozone application in periodontitis: an experimental study in rats

J. appl. oral sci; 28 (), 2020
Abstract Objective: The goal of the present study was to determine the effect of systemic and topical ozone application on alveolar bone loss (ABL) by evaluating the effect of Hypoxia-inducible factor −1 alpha (HIF-1-α) and receptor activator of NF-kB ligand (RANKL)-positive cells on histopat...

Acrylamide reduces plasma antioxidant vitamin levels in rats due to increased oxidative damage

Rev. Nutr. (Online); 33 (), 2020
ABSTRACT Objective Acrylamide is a potentially neurotoxic and carcinogenic chemical and naturally creates during the heating process of carbohydrate-rich foods, such as potato chips and breakfast cereals. Acrylamide might be ingested by people via consuming food that contains it. Therefore, we investiga...

Evaluation of the effects of diode laser application on experimental orthodontic tooth movements in rats. Histopathological analysis

Acta cir. bras; 35 (12), 2020
Abstract Purpose: To evaluate the effect of diode laser use on experimental orthodontic tooth movements. Methods: Thirty Rattus norvegicus albinus Wistar were divided into three equal groups (n = 10), two experimentals and one control. Applying 20 g orthodontic force were attached to the maxillary inci...

Experimental evaluation of intra-abdominal adhesions comparing two different intraperitoneal meshes and the effect of a natural anti-inflammatory product on their formation

Acta cir. bras; 35 (12), 2020
Abstract Purpose: In laparoscopic incisional hernia repair, meshes with a tissue-separating barrier are positioned intraperitoneally. Despite this property, the close contact between mesh and viscera involves a risk of adhesion formation. Some natural products, such as red propolis (RP), could reduce th...

Reconstruction of parietal bone defects with adiposederived mesenchymal stem cells. Experimental study

Acta cir. bras; 35 (12), 2020
Abstract Purpose: This study assessed the regeneration potential of mesenchymal stem cells (MSC) from adipose tissue associated with platelet-rich plasma (PRP) in bone regeneration. Methods: Thirty Wistar rats (Rattus norvegicus albinos) were divided into five groups (according to the grafting material...

Remote ischemic conditioning protects against testicular ischemia∕reperfusion injury in rats

Acta cir. bras; 35 (2), 2020
Abstract Purpose To evaluate the effect of remote ischemic conditioning associated to N-acetylcysteine (NAC) on testicular ischemia∕reperfusion (I∕R) injury in rats. Methods Twenty-five adult male Wistar rats were randomly distributed into five experimental groups (n=5), as follows: Sham,...

Does a bilateral polypropylene mesh alter the duct deferens morphology, testicular size and testosterone levels? Experimental study in rats

Acta cir. bras; 35 (2), 2020
Abstract Purpose To evaluate the effect of a PP mesh on duct deferens morphology, testicular size and testosterone levels. Methods Forty adult male rats were distributed into groups: 1) no surgery; 2) inguinotomy; 3) mesh placed on the duct deferens; and 4) mesh placed on the spermatic funiculus. Aft...

Resistance training improves the lipid profile, combat oxidative stress and inhibit MMP-2 activity in the left ventricle diet-induced obese rats

Motriz (Online); 26 (3), 2020
Abstract Aims: The purpose of the present study was to evaluate the effects of the resistance training (RT) on the lipid profile and metabolism, oxidative stress, and activity of metalloproteinase-2 (MMP-2) in the left ventricle (LV) of diet-induced obesity rats. Methods: Forty males Wistar rats 90 d...

Moderate-intensity exercise training improves long-term memory in fructose-fed rats

Motriz (Online); 26 (4), 2020
Abstract Aim: Animal disease model studies are widely used to show the effectiveness of physical exercise to improve cognitive function. Thus far, few studies are investigating the effects of exercise training on memory performance in fructose feed animals. Method: The present study investigated the ...

Moderate intensity swimming training on bone mineral density preservation under food restriction in female rats

Motriz (Online); 26 (4), 2020
Abstract Aim: To investigate the effect of moderate-intensity swimming training on bone mineral density under a 20% food restriction (FR) schedule for 12 weeks in female rats. Methods: Forty female Wistar rats were distributed into four groups: control (CG), exercised (EG), food restriction (FRG), and...
