1. Crack Propagation Analysis of Magnesium Rod Processed by Extrusion-shear: Numerical Modeling and Experimental Verification
During extrusion-shear (ES) process, the surface cracks would be formed in the processed rod for AZ31 magnesium caused by nonhomogeneous metal flow and stress. To reduce the cracks defects, three-dimensional (3D) finite element method (FEM) of ES on a wrought AZ31 magnesium alloy have been performed. ES process experiments have been also conducted to verify

2. Effect of a multi-layer infection control barrier on the micro-hardness of a composite resin
OBJECTIVE: The aim of this study was to evaluate the effect of multiple layers of an infection control barrier on the micro-hardness of a composite resin. MATERIAL AND METHODS: One, two, four, and eight layers of an infection control barrier were used to cover the light guides of a high-power light emitting diode (LeD) light curing unit (LCU) and a low-power

3. Exercise training and detraining modify the morphological and mechanical properties of single cardiac myocytes obtained from spontaneously hypertensive rats
We determined the effects of exercise training and detraining on the morphological and mechanical properties of left ventricular myocytes in 4-month-old spontaneously hypertensive rats (SHR) randomly divided into the following groups: sedentary for 8 weeks (SED-8), sedentary for 12 weeks (SED-12), treadmill-running trained for 8 weeks (TRA, 16 m/min, 60 min/

4. Razão de sacrifício em países emergentes e em desenvolvimento
The sacrifice ratio is calculated with the purpose of estimating a model through Ordinary Least Squares (OLS), in which both sample selection and high income economies are controlled, in order to test whether sacrifice ratios of emerging and depeloping economies is affected by velocity of desinflation, by the fact of a country being an inflation targeter and

5. Experimental study and genetic expression on wound healing of alveolar bone sockets after cigarette smoke inhalation in rats / Influencia da inalação da fumaça de cigarro sobre o processo de reparo osseo alveolar : estudo histometrico e de regulação genica em ratos
The aim of the present study was to evaluate the effect of cigarette smoke inhalation on wound healing of molar extraction socket. A total of 40 male Wistar rats were randomly assigned to one of the following groups: Control Group - 20 animals not exposed to cigarette smoke inhalation (CSI) and Test Group - 20 animals exposed to CSI for 3 days before the sur

6. Inflation targeting and the sacrifice ratio
Neste artigo mostramos que os países que adotaram o regime de Metas de Inflação (IT) lograram desinflar suas economias com menores custso. O efeito da dummy IT é estatística e economicamente bem significativo. Ao reduzir significativamente os custos das desinflações, este sistema pode tornar níveis mais baixos de inflação politicamente mais factív

7. Avaliação do estresse oxidativo e estado redox mitocondrial na hepatotoxicidade induzida pela cisplatina em ratos Wistar: efeito protetor da dimetiltiouréia / Evaluation of mitochondrial oxidative stress and redox state in the cisplatin-induced hepatotoxicity in Wistar rats: protective effect of dimethylthiourea
Cisplatin is still one of the most effective chemotherapeutic agents. However, at higher doses hepatotoxicity may occur. Some antioxidants have been shown to ameliorate cisplatin-induced hepatotoxicity but the involved molecular mechanism has not been clarified. In the present study we investigated the molecular mechanism underlying the protective effect of

8. A experiência de Chile, México e Brasil sob o regime de metas de inflação : uma comparação internacional
Esta dissertação tem o propósito de avaliar a experiência de Brasil, Chile e México comparativamente a de Austrália, Finlândia, Suécia, Reino Unido, Nova Zelândia e Canadá sob o regime de metas inflação (IT). Dessa forma, o interesse central deste estudo é o efeito das políticas monetárias adotadas sobre produto dos países emergentes, em um c

9. Semen cryopreservation of rainbow trout XX-males. / CriopreservaÃÃo do sÃmen de machos-XX de truta arco-Ãris (Oncorhynchus mykiss)
This study was carried out during July and August of 2005 and 2006. The aim of this study was to improve the cryopreservation techniques for semen cryopreservation of sex-reversed rainbow trout males (XX-males). The first session of experiments, only semen collected under abdominal massage was used. In experiment 1, four semen extenders (glucose 5,4%, NaCl 0

10. Anabolic steroid- and exercise-induced cardiac stress protein (HSP72) in the rat
The present study investigated the effects of exercise and anabolic-androgenic steroids on cardiac HSP72 expression. Male Wistar rats were divided into experimental groups: nandrolone exercise (NE, N = 6), control exercise (CE, N = 6), nandrolone sedentary (NS, N = 6), and control sedentary (CS, N = 6). Animals in the NE and NS groups received a weekly intra

11. Avaliação da influência de diferentes inóculos do isolado humano (Portland -I) de Giardia duodenalis sobre a cinética da infecção e no desenvolvimento de alterações patológicas no intestino delgado de gerbils (Meriones unguiculatus) experimentalmente infectados
Giardia duodenalis is, today, considered serious problem of public health attacking individuals, independent of characteristics cultural or socioeconomic. To compare the kinetics of the infection and pathological alterations in the small intestine, produced by Giardia duodenalis, 72 gerbils, were divided in 6 groups (A to F), being A the control and the othe

12. Estrogen enhances vasoconstrictive remodeling after injury in male rabbits
The complete spectrum of estrogen vascular effects remains unclear. In particular, estrogen effects in the vascular response to profound injury in males have not been explored in detail. Therefore, we submitted 44 male New Zealand rabbits weighing 3.4 ± 0.6 kg to overdistention balloon injury of the right iliac artery. Rabbits were given 17ß-estradiol (5.4
