Morphological and molecular analysis of apoptosis in the corpus cavernosum of rats submitted to a chronic alcoholism model

Acta cir. bras; 35 (3), 2020
Abstract Purpose To evaluate the effect of chronic alcoholism on morphometry and apoptosis mechanism and correlate with miRNA-21 expression in the corpus cavernosum of rats. Methods Twenty-four rats were divided into two experimental groups: Control (C) and Alcoholic group (A). After two weeks of an ...

Effects of bradykinin preconditioning in an experimental intestinal ischemia reperfusion model on rats

Acta cir. bras; 35 (4), 2020
Abstract Purpose To investigate the effects of bradykinin on reperfusion injury in an experimental intestinal ischemia reperfusion model. Methods We used 32 Wistar-Albino rats. We composed 4 groups each containing 8 rats. Rats in sham group were sacrified at 100 minutes observation after laparotomy. ...

Histological analysis of the intestinal wall of newborn rats submitted to hypoxia and reoxygenation to evaluate the protective effect of N-Acetylcysteine

Acta cir. bras; 35 (4), 2020
Abstract Purpose To evaluate the effect of N-Acetylcysteine (NAC) in newborn rats submitted to hypoxia and reoxygenation (H/R) conditions in an experimental model of necrotizing enterocolitis. Methods Eight pregnant rats and their 70 cubs were used (5 groups) and exposed to H/R conditions and receive...

Mechanical properties of the sciatic nerve following combined transplantation of analytically extracted acellular allogeneic nerve and adipose-derived mesenchymal stem cells

Acta cir. bras; 35 (4), 2020
Abstract Purpose To investigate the effects of Chemically Extracted Acellular Nerves (CEANs) when combined with Adipose-Derived mesenchymal Stem Cell (ADSC) transplantation on the repair of sciatic nerve defects in rabbits. Methods A total of 71 six-month-old Japanese rabbit were used in this study. ...

The effect of rosmarinic acid on deformities occurring in brain tissue by craniectomy method. Histopathological evaluation of IBA-1 and GFAP expressions

Acta cir. bras; 35 (4), 2020
Abstract Purpose To investigate the role of Rosmarinic acid (RA) in the prevention of traumatic brain injury and the immunohistochemical analysis of IBA-1 and GFAP expressions. Methods Healthy male rats were randomly divided into 3 groups consisting of 10 rats. Groups were as follows; control group, tr...

Methods This is an experimental study with 12 albino ...

Diagnostic accuracy of 18F-FDG-PET in abdominal sepsis in rats

Acta cir. bras; 35 (5), 2020
Abstract Purpose The objective of this study was to investigate the accuracy of 18F-FDG-PET in the diagnosis of multibacterial abdominal sepsis by cecum ligation and puncture (CLP) in rats. Methods Adult Wistar rats ( Rattus norvegicus ), weighing 227±35g, were allocated into a sepsis group by CLP (...

Correlation between mechanical properties and stabilization time of chemical bonds in glass-ionomer cements

Abstract The objective was to evaluate the compressive strength (CS), diametral tensile strength (DTS), flexural strength (FS), and Knoop microhardness (KH) of different conventional restorative glass-ionomer cements (GICs) and to correlate these mechanical properties (MP) with the stabilization time (ST...

Gene expression profile of Scardovia spp. in the metatranscriptome of root caries

Abstract A few investigations of caries biofilms have identified Scardovia spp.; however, little is known about its involvement in caries pathogenesis. The purpose of this study was to assess the gene expression profile of Scardovia spp. in root caries, and compare it with other microorganisms. Clinical ...

Relationship between periodontitis and subclinical risk indicators for chronic non-communicable diseases

Abstract In view of the epidemiological relevance of periodontal disease and chronic noncommunicable diseases, the study aimed to evaluate the relationship between them through subclinical indicators of systemic risk in a population group with healthy habits, including alcohol and tobacco abstinence. A c...
