13. A case of acquired tufted angioma in adulthood
AbstractTufted angioma is a rare vascular tumor whose name derives from its histopathological appearance, characterized by tufts of capillaries within the dermis. Its etiology and pathogenesis are uncertain. Tufted angioma typically occurs during infancy or early childhood and displays various clinical patterns. It may present as a subtle stain-like area tha

14. CONSTRUÇÃO DE UM DISPOSITIVO DE PRESSURIZAÇÃO A VÁCUO PARA A PREPARAÇÃO DE FASES ESTACIONÁRIAS MONOLÍTICAS VIA PROCESSO SOL-GEL
The filling of capillaries via the sol-gel process is growing. Therefore, this technical note focuses on disseminating knowledge acquired in the Group of Analytical Chemistry and Chemometrics over seven years working with monolithic stationary phase preparation in fused silica capillaries. We believe that the detailed information presented in this technical

15. Modeling pulmonary fibrosis by abnormal expression of telomerase/apoptosis/collagen V in experimental usual interstitial pneumonia
Limitations on tissue proliferation capacity determined by telomerase/apoptosis balance have been implicated in pathogenesis of idiopathic pulmonary fibrosis. In addition, collagen V shows promise as an inductor of apoptosis. We evaluated the quantitative relationship between the telomerase/apoptosis index, collagen V synthesis, and epithelial/fibroblast rep

16. Experimental model of obtaining tissue adipose, mesenchymal stem cells isolation and distribution in surgery flaps in rats
PURPOSE:To investigate the experimental model for obtaining adipose tissue, isolation, characterization of mesenchymal stem cells and evaluation of their distribution in the tram flap in rats.METHODS:Five rats of Wistar were randomly assigned to two groups. In group I, three animals underwent removal of adipose tissue in the groin procedure to establish the

17. Histological modification in TRAM flap in rats treated with pentoxifylline
PURPOSE:To investigate the blood vessels' concentration in TRAM flap's rat model, in the presence of pentoxifylline.METHODS: 32 male, Wistar-EPM rats were divided into two groups. Control group (C): 0.5 ml of saline, intraperitoneally, once a day, for seven days before flap elevation; PTX group (P): pentoxifylline (20mg/kg/day), intraperitoneally, for seven

18. Heart injury following intestinal ischemia reperfusion in rats is attenuated by association of ischemic preconditioning and adenosine
PURPOSE:To investigate the effect of ischemic preconditioning (IPC) and adenosine as strategies to protect cardiac injury caused by intestinal IR in rats, based on increasing in adenosine bioavailability and improvement of cell energy state by IPC.METHODS: Male Wistar rats were submitted to 60 minutes of intestinal ischemia and 120 minutes of reperfusion.

19. Geração de harmônicos de pulsos laser de femtossegundo pela técnica de conversão de frequência em capilares preenchidos com gases nobres / Harmonics generation of femtosecond laser pulses by the technique of frequency conversion in noble gas filled capillaries
O propósito principal desta tese foi a implementação e estudo da geração de pulsos laser de femtossegundos em comprimentos de onda curtos (ultravioleta profundo, ultravioleta de vácuo e ultravioleta extremo) pela técnica de conversão de frequência em capilar preenchido com gás nobre. Esta técnica de conversão de frequência tem feito diversas con

20. Fenofibrato (agonista do receptor ativador da proliferação peroxissomal) modula o sistema renina-angiotensina no coração de camundongos alimentados com dieta hiperlipídica / Fenofibrate (peroxisome proliferator-activated receptor alpha agonist) modulates the renin-angiotensin system in the heart of mice fed with a high-fat diet
The aim was to study the action of fenofibrate, a peroxisome proliferator-activated receptor alpha agonist, in cardiac remodeling and protein expressions of RAS components in a model of obesity induced by diet. 3-mo-old C57BL/6 male were fed for 11 weeks with standard chow (SC group, 3.57 kcal/g of chow) or high-fat chow (HF group, 5.40 kcal/g of chow), then

21. Desenvolvimento e aplicação de biorreatores capilares para a triagem de ligantes de Purina Nucleosídeo Fosforilases / Development and application of capillary bioreactors for screening of Purine Nucleoside Phosphorylases ligands
Purine Nucleoside Phosphorylases (PNPs) are key enzymes of the purine salvage pathway, and therefore are considered attractive targets for new drugs search. In this context, the development of effective and selective bioassays for PNP ligands screening is an important task. This work describes the covalent immobilization of human and Schistossoma mansoni PNP

22. Acute and subchronic toxicological evaluation of Echinophora platyloba DC (Apiaceae) total extract in Wistar rats
OBJECTIVE: Echinophora platyloba DC is a widely used herbal medicine and food seasoning in Iran. It is claimed to exert antimicrobial, antifungal, and antispasmodic effects. Despite the prevalent use of this plant as a food and medicine, there are no reports on its possible toxic effects. To evaluate the safety of E. platyloba, we tested its acute and sub-ch

23. NUMERICAL ANALYSIS OF THE FLOW OF EMULSION THROUGH STRAIGHT AND CONSTRICTED CAPILLARIES / ANÁLISE NUMÉRICA DO ESCOAMENTO DE EMULSÕES ATRAVÉS DE CAPILARES RETOS E CAPILARES COM GARGANTA
Emulsion can be used as a mobility control agent in enhanced oil recovery methods in order to achieve a more efficient sweep of the reservoir. The application of such technique requires full understanding of how emulsions flow in a porous material. The macroscopic flow behavior can be determined based on the pore scale flow, at which emulsions cannot be trea

24. Effect of gender on training-induced vascular remodeling in SHR
There is accumulating evidence that physical inactivity, associated with the modern sedentary lifestyle, is a major determinant of hypertension. It represents the most important modifiable risk factor for cardiovascular diseases, which are the leading cause of morbidity and mortality for both men and women. In addition to involving sympathetic overactivity t
