Background:There is equivocal evidence regarding differences in the clinical course and outcomes of Crohn’s disease(Cd)among African Americans compared with Caucasian *** sought to analyze whether African Americans with Cd are more likely to be hospitalized for Cd-related complications when compared with Caucasian Americans with ***:We conducted a retrospective cohort study including 909 African Americans and Caucasian Americans with Cd who were seen at our tertiary care Inflammatory Bowel disease(IBd)referral center between 2000 and *** calculated the rate of hospitalization for Cd-related complications among African Americans and Caucasian Americans ***-inflated Poisson regression models with robust variance estimates were used to estimate crude and multivariable adjusted rate ratios(RR)for Cd-related *** adjusted models included adjustment for age,sex,duration of Cd,smoking and Cd ***:The cumulative rate of Cd-related hospital admissions was higher among African American patients compared with Caucasian American patients(395.6/1000 person-years in African Americans vs.230.4/1000 person-years in Caucasian Americans).Unadjusted and multivariable adjusted rate ratios for Cd-related hospitalization comparing African Americans and Caucasian Americans were 1.59(95%confidence interval[95%CI]:1.10–2.29;P=0.01)and 1.44(95%CI:1.02–2.03;P=0.04),***:African Americans with Cd followed at a tertiary IBd-referral center had a higher rate for Cd-related hospitalizations compared with Caucasian *** studies should examine whether socioeconomic status and biologic markers of disease status could explain the higher risk observed among African Americans.

Evaluation of Tomato Lines derived from Landraces of ＂Tomate Platense＂ and a Commercial Hybrid in La Plata, Argentina

引用

Journal of Agricultural Science and Technology(B) 2016年第2期6卷 78-82页

In the city of La Plata （Argentina） and the surroundings, there are tomato landraces, widely known as ＂tomate platense＂ and particularly prized because of their flavor. The objective was to evaluate seven promissory lines of ＂tomate platense＂（TL） derived from local varieties and a commercial hybrid （CH） considering yield, fruit characters and their possible associations. Nine plants per treatment were arranged in a randomized complete block design （r = 4）. The following parameters were determined： diameter （cm）, height （cm）, diameter/height （d/H） ratio, weight per fruit （g）, number of locules, the average number of fruits per plant, the average weight of fruits per plant （kg/ptant）, the yield （ton/ha） and the survival percentage. ANOVA, Tukey＇s test and Pearson correlation coefficient were applied. The TL showed greater （P ≤ 0.01） diameter, d/H ratio and number of locules than CH. In all materials, both diameter and height were associated （P ≤ 0.05） with the weight per fruit. Six of TL had greater （P ≤ 0.01） weight per fruit than HC. Respect to number of fruits per plant, weight of fruits per plant and yield, there were no significant differences among the materials. The survival for CH was lower （P ≤0.05） than that for TL. Although fruits with a smaller size and less flattened have been selected, the lines show enough similarity in these characters that identified their common origin. With the fruits smaller and more uniform, and having no joined fruits, these lines may be of interest to be cultivated under low-input system conditions and practical for low-income producers.
