AIM: To analyze the effect of age-period and birth cohort on gastric cancer mortality, in Brazil and across its five geographic regions, by sex, in the population over 20 years of age, as well as make projections for the period ***: An ecological study is presented herein,which distributed gastric cancer-related deaths in Brazil and its geographic regions. The effects of ageperiod and birth cohort were calculated by the Poisson regression model and projections were made with the age-period-cohort model in the statistical program R. RESULTS: Progressive reduction of mortality rates was observed in the 1980's, and then higher and lower mortality rates were verified in the 2000's, for both sexes, in Brazil and for the South, Southeast and Midwest regions. A progressive decrease in mortality rates was observed for the Northeast(both sexes) and North(men only) regions within the period 1995-1999, followed by rising rates. CONCLUSION: Regional differences were demonstrated in the mortality rates for gastric cancer in Brazil, and the least developed regions of the country will present increases in projected mortality rates.

A thrombin-like serine protease, jararassin-I, was isolated from the venom of Bothrops jararaca. The protein was obtained in high yield and purity by a single chromatographic step using the affinity resin Benzamidine-Sepharose CL-6B. SDS-PAGE and dynamic light scattering analyses indicated that the molecular mass of the enzyme was about 30 kD. The enzyme possessed fibrinogenolytic and coagulant activities. The jararassin-I degraded the Bβ chain of fibrinogen while theAα chain and γ chain were unchanged. Proteases inhibitors, PMSF and benzamidine inhibited the coagulant activity. These results showed jararassin- I is a serine protease similar to coagulating thrombin-like snake venom proteases, but it specifically cleaves Bβ chain of bovine fibrinogen. Single crystals of enzyme were obtained (0.2 mm×0.2 mm×0.2 mm) and used for X-ray diffraction experiments.

Abstract： This study deals with the Fe65.5Cr4Mo4Ga4P12C5B5.5 ferromagnetic bulk amorphous alloy. XRD analysis showed an amorphous structure of the as-cast sample. The same method revealed that, after annealing at 973 K for v=10 min, the sample displayed a crystalline structure with crystalline phases formed. The crystallization process of the alloy was examined by DTA analysis. It was shown that crystallization took place in the temperature range between 810 K and 860 K with the exo-maximum peak temperature at 846 K with a heating rate of 20 ***-1. The method also showed that, at temperatures ranging from 753 K to 810 K, the alloy exhibited the properties of supercooled liquids. A correlation between heat-induced structural changes and magnetic properties of the alloy was determined by thermomagnetic measurements. Maximum magnetization M=3.7 ***-1 of the alloy was reached after its annealing at 733 K for τ=10 min. Upon annealing, the alloy exhibited a relaxed amorphous structure. Annealing the alloy above the crystallization temperature led to a decrease in bulk magnetization. After annealing at 973 K for r=10 min, the bulk magnetization of the alloy was M＇=0.45 ***-1. Accordingly, after crystallization and formation of new compounds, the magnetization of the alloy was decreased by a factor of about 7.7. The strength of the magnetic field applied during the measurements was H=10 kA.m-1. The samples were tested for changes in the microstructure and hardness of both the amorphous phase and the resulting crystalline phase.

Esophageal and gastric cancer(GC) are related to obesity and bariatric surgery. Risk factors, such as gastroesophageal reflux and Helicobacter pylori, must be investigated and treated in obese population. After surgery, GC reports are anecdotal and treatment is not standardized. This review aims to discuss GC related to obesity before and after bariatric surgery.
