25. Estudo dos efeitos celulares e vasculares da criocirurgia com nitrogênio líquido, na pele de ratos, por método histopatológico / The study of cellular and vascular effects of cryosurgery with liquid nitrogen, in rat skin, using the histopathological method
Cryosurgery is a very efficient therapeutic technique to treat benign and malignant cutaneous diseases. The primary active mechanism of cryosurgery is related to vascular effects in treated tissue. After a cryosurgical procedure, exuberant granulation tissue is formed at the injection site, probably as a result of angiogenic stimulation of the cryogen and in

26. ROTA DE AÇÃO DA PROSTAGLANDINA F2 ADMINISTRADA VIA SUBMUCOSA VULVAR NA LUTEÓLISE DE BOVINOS / ROUTE OF ACTION OF PROSTAGLANDIN F2 AFTER INTRAVULVOSUBMUCOUS INJECTION IN BOVINE LUTEOLYSIS
The aim of this study was to verify if prostaglandin F2 (PGF2) administered by intravulvosubmucous (IVSM) injection induces luteolysis by reaching the corpus luteum (CL) directly by a local absorption rote, preventing its metabolism in the lungs, or after absorption and distribution via the systemic circulation. In a first trial, the estrus rate of 1,937 bee

27. Anesthetic technique for inferior alveolar nerve block: a new approach
BACKGROUND: Effective pain control in Dentistry may be achieved by local anesthetic techniques. The success of the anesthetic technique in mandibular structures depends on the proximity of the needle tip to the mandibular foramen at the moment of anesthetic injection into the pterygomandibular region. Two techniques are available to reach the inferior alveol

28. The impact of previous para-areolar incision in the upper outer quadrant of the breast on the localization of the sentinel lymph node in a canine model
OBJECTIVES: This paper discusses the influence of a para-areolar incision in the upper outer quadrant of the breast on the location of the sentinel lymph node in a canine model. METHODS: The sentinel lymph node was marked with technetium-99, which was injected into the subareolar skin of the cranial breast. After the marker had migrated to the axilla, an arc

29. Desenvolvimento de modelos animais de terapia gênica para o hormônio de crescimento utilizando queratinócitos transduzidos e injeção direta de DNA plasmidial / Development of animal models of growth hormone gene therapy using transduced keratinocytes and direct injection of naked DNA
Queratinócitos são células bastante atrativas para a transferência gênica ex vivo e liberação sistêmica, uma vez que as proteínas secretadas por estas células podem atingir a circulação via um mecanismo similar ao processo natural. No presente trabalho, queratinócitos transduzidos mediante um vetor retroviral com o gene do hormônio de crescimen

30. Cyclosporin A-induced gingival overgrowth is not associated with myofibroblast transdifferentiation
Cyclosporin A (CyA) induces gingival overgrowth via its stimulatory effects on expression of transforming growth factor-beta1 (TGF-β1) and collagen. It is not known whether CyA has a direct effect on gingival fibroblasts or induces its effect indirectly via stimulation of myofibroblast transdifferentiation. The present study was undertaken to examine the in

31. SOYBEANS BIODIESEL BLENDS, WITH ADDITIVES AND VARYING INJECTION TIMING, IN A DIRECT INJECTION ENGINE / MISTURAS DE BIODIESEL DE SOJA, COM ADITIVAÇÃO E VARIAÇÃO DO PONTO DE AVANÇO, EM UM MOTOR DE INJEÇÃO DIRETA
O óleo diesel combustível é utilizado em grande escala no país e no mundo. Por outro lado, a crescente conscientização ambiental acarreta em uma maior demanda por recursos energéticos renováveis. O pioneirismo no uso do etanol faz com que o Brasil também ostente condições de avançar rapidamente na consolidação do uso do biodiesel em maiores esc

32. Experimental model of gene transfection in healthy canine myocardium. Perspectives of gene therapy for ischemic heart disease
Objective - To assess the transfection of the gene that encodes green fluorescent protein (GFP) through direct intramyocardial injection. Methods - The pREGFP plasmid vector was used. The EGFP gene was inserted downstream from the constitutive promoter of the Rous sarcoma virus. Five male dogs were used (mean weight 13.5 kg), in which 0.5 mL of saline soluti

33. Analytical method development for determination of codeine in human plasma by on-line SPE-HPLC-MS/MS / Desenvolvimento de metodologia analitica para determinação de codeina em plasma humano utilizando extração solido-liquido "on-line" acoplado ao HPLC-MS/MS
A specific LC-MS/MS method was developed and validated for automated determination of codeine in human plasma, using on-line solid-phase extraction (SPE) system coupled with positive ion electrospray ionization tandem mass spectrometry. Method allowed plasma direct injection onto cartridge without sample pre-treatment. Total analysis time per run was 3 min,

34. Reduced cortical renal GLUT1 expression induced by angiotensin-converting enzyme inhibition in diabetic spontaneously hypertensive rats
Diabetes in spontaneously hypertensive rats is associated with cortical renal GLUT1 and GLUT2 overexpression. Our objective was to evaluate the effect of the angiotensin-converting enzyme blockade on cortical renal GLUT1 and GLUT2 expression, urinary albumin and urinary TGF-β1. Streptozotocin, 50 mg/kg, or citrate buffer (N = 16) was administered as a singl

35. Characterization of the actions of Crotalus durissus terrificus venon on neutrophils functions / Caracterização das ações do veneno de Crotalus durissus terrificus sobre funções de neutrófilos
Previous studies showed that Crotalus durissus terrificus snake venom (CdtV) has long-lasting anti-inflammatory properties and inhibits the spreading and the phagocytic activity of peritoneal macrophages. Crotoxin (CTX), the main component of CdtV, is responsible for these effects. In addition, CdtV inhibits, in vitro and in vivo, the phagocytic activity of

36. Desenvolvimento e otimização de metodologia para análise de edulcorantes por Eletroforese Capilar
An innovative methodology was developed to simultaneously separate and quantify aspartame, cyclamate, saccharin and acesulfame-K through capillary electrophoresis with direct and indirect detection of UV, analysis time of roughly 6 minutes and with no sample derivatization. As the cyclamate has low absorptivity we used a system of electrolyte added to a chro
