1. Ozone combined with doxorubicin exerts cytotoxic and anticancer effects on Luminal-A subtype human breast cancer cell line
SUMMARY OBJECTIVE: We aimed to examine the potential anticancer effects of ozone applied after chemotherapeutic treatment with different concentrations of doxorubicin in Luminal-A subtype of human breast cancer cell line (MCF-7) and compare the results with effects on L929 fibroblast cell line. METHODS: Both cell lines were incubated with increasing doses

2. A new option to prevent fistulas in anterior urethroplasty in patients with kippered urethra: the tunica vaginalis flap
ABSTRACT The objective of this study is describing a technique with the use of a tunica vaginalis flap (TVF) to cover the suture line during anterior urethroplasty in patients with kippered urethra due to chronic indwelling catheterization (CIC). We studied 5 patients (mean age=50.2) with a neurogenic bladder that developed urethral erosion after a long peri

4. Twenty-Five Years of No-Touch Saphenous Vein Harvesting for Coronary Artery Bypass Grafting: Structural Observations and Impact on Graft Performance
Abstract The saphenous vein is the most common conduit used in coronary artery bypass grafting (CABG) yet its failure rate is higher compared to arterial grafts. An improvement in saphenous vein graft performance is therefore a major priority in CABG. No-touch harvesting of the saphenous vein is one of the few interventions that has shown improved patency ra

5. Evaluation of dentinogenesis inducer biomaterials: an in vivo study
Abstract When exposure of the pulp to external environment occurs, reparative dentinogenesis can be induced by direct pulp capping to maintain pulp tissue vitality and function. These clinical situations require the use of materials that induce dentin repair and, subsequently, formation of a mineralized tissue. Objective: This work aims to assess the effect

6. Suppresses of Astragalus Polysaccharide on E. coli-Induced Injured Intestinal Microvascular through TLR4-NF-κB Signal Pathways in Chickens
ABSTRACT To investigate the hypothesis that APS can attenuate E. coli-induced microvascular dysfunction in chicken intestine, 60 0-day old male chickens were divided into three groups with 5 replications of 4 chicks. Chicken in the APS group were treated with 15 mg APS daily while the others were given 0 mg APS for 6 days. Then all 7-day old chicken were inj

8. Brushite cement containing gelatin: evaluation of mechanical strength and in vitro degradation
Resumo Os cimentos de fosfato de cálcio (CPCs) são materiais potenciais para reparar defeitos ósseos, principalmente devido à sua excelente biocompatibilidade e osteocondutividade. No entanto, suas baixas propriedades mecânicas limitam suas aplicações clínicas. A adição de gelatina pode melhorar as propriedades mecânicas e biológicas dos CPCs, ma

9. Modified Arthroscopic McLaughlin Procedure in the Treatment of Posterior Glenohumeral Instability- Technical Note
Resumo A luxação do ombro posterior traumática é de difícil diagnóstico e tratamento. Há séries que descrevem que 60%-80% dessas luxações não são diagnosticadas numa primeira ida ao serviço de urgência. Desse modo, casos de luxações com vários dias e por vezes semanas são frequentes, o que sempre torna o tratamento mais complexo. As luxaç�

10. Fatigue Failure Analysis on Precracked 304 Stainless Steel Components Repaired by Laser with Addition of Nanocomposites
Abstract The service life of components can be extended by repairing fatigue crack with laser so as to improve resource utilization rate. However, the effect of laser repair may be influenced by the instability of laser treatment. To investigate the addition of nanocomposites on the laser repairing effect, fatigue test under uniaxial tension was carried out

11. Tratamento endovascular de aneurisma isolado bilateral de artéria ilíaca interna
Resumo Os aneurismas isolados das artérias ilíacas representam menos de 2% de todos os aneurismas abdominais. A artéria ilíaca interna é acometida em 10-30% dos casos. Na maioria dos casos os pacientes são assintomáticos, exceto se houver ruptura. Os aneurismas podem ser diagnosticados por ultrassom Doppler, ressonância magnética ou, preferencialmen

12. Flexural Strengthening of Reinforced Concrete Beams Using Carbon Fiber Reinforced Polymer (CFRP) Sheets with Grooves
Abstract The most common method used to strengthening, rehabilitation or repairing of reinforced concrete (RC) members is to use external carbon fiber reinforced polymer (CFRP) sheets. CFRP can greatly improve the flexural and shear capacity of deteriorated members and therefore extends their useful life. The main problem of external CFRP is the debonding of
