The expression of endothelial and inducible nitric oxide synthase and apoptosis in intestinal ischemia and reperfusion injury under the action of ischemic preconditioning and pentoxifylline

Acta cir. bras; 32 (11), 2017
Abstract Purpose: To investigate the expression of nitric oxide synthase (NOS) and apoptosis associated with ischemic preconditioning (IPC) and pentoxifylline (PTX) in intestinal ischemia (I) and reperfusion (R) injury. Methods: Thirty male rats were assigned to 5 groups: (CG), no clamping of the sup...

Tadalafil protector effect during ischemia-reperfusion in rats

Acta cir. bras; 32 (11), 2017
Abstract Purpose: To evaluate histological parameters in rat renal tissue after tadalafil use during hot ischemia for 45 minutes and reperfusion for 24 hours. Methods: Twenty rats were divided into 2 groups. In the experimental group 10 mg/kg of tadalafil was used per gavage before the procedure. All...

Genotyping and antimicrobial resistance in Escherichia coli from pig carcasses

Pesqui. vet. bras; 37 (11), 2017
The increasing antimicrobial resistance observed worldwide in bacteria isolated from human and animals is a matter of extreme concern and has led to the monitoring of antimicrobial resistance in pathogenic and commensal bacteria. The aim of this study was to evaluate the antimicrobial resistance profile ...

Phytosterols in the Treatment of Hypercholesterolemia and Prevention of Cardiovascular Diseases

Arq. bras. cardiol; 109 (5), 2017
Abstract Phytosterols are bioactive compounds found in foods of plant origin, which can be divided into plant sterols and plant stanols. Clinical studies consistently indicate that the intake of phytosterols (2 g/day) is associated with a significant reduction (8-10%) in levels of low-density lipoprotein...

Lack of association between rrl and erm(41) mutations and clarithromycin resistance in Mycobacterium abscessus complex

Mem. Inst. Oswaldo Cruz; 112 (11), 2017
BACKGROUND Mycobacterium abscessus complex (MABC) includes species with high resistance rates among mycobacterial pathogens. In fact, MABC infections may not respond to clarithromycin treatment, which has historically been very effective against MABC infection. Molecular markers have been proposed to det...

Cytotoxic activity in cutaneous leishmaniasis

Mem. Inst. Oswaldo Cruz; 112 (11), 2017
Cutaneous leishmaniasis (CL) is a chronic disease caused by species of the protozoan Leishmania and characterised by the presence of ulcerated skin lesions. Both parasite and host factors affect the clinical presentation of the disease. The development of skin ulcers in CL is associated with an inflammat...

Antimicrobial susceptibility patterns of Brazilian Haemophilus parasuis field isolates

Pesqui. vet. bras; 37 (11), 2017
Haemophilus parasuis is the etiological agent of Glässer's disease (GD), an ubiquitous infection of swine characterized by systemic fibrinous polyserositis, polyarthritis and meningitis. Intensive use of antimicrobial agents in swine husbandries during the last years triggered the development of antibio...

Economic assessment of postoperative pain control strategies for treatment of adult patients with cancer

Summary Objective: The authors performed an economic assessment of opioids currently being used for control of postoperative pain relating to the surgical treatment of cancer (fentanyl and sufentanil) within the Brazilian Unified Health System (SUS, in the Portuguese acronym). Method: The assessment wa...
