Early detection of infected asymptomatic plants could prevent the dissemination of tomatobacterial canker throughout the crop and, thus, reduce associated economic losses. Reflectance spectroscopy has been proposed for the detection of diseases in plants, mainlycaused by foliar fungal pathogens. In contrast, bacterial canker is a vascular disease thatdoes not produce visible foliar symptoms until it is too late to avoid contagion to otherplants. The effects of the disease on the conductivity of the xylem have an impact onthe water content of the leaves;initially, a subtle effect that cannot be assessed with thenaked eye but can be evaluated by reflectance spectroscopy. The objective of this workwas to identify indices, based on the reflectance spectral signature of the plants, for thedetection of tomato plants affected by bacterial canker prior to the appearance of symptoms. To verify that the proposed methodology is applicable to a broad range of tomatogenotypes, two experiments were carried out with different tomato cultivars grown in potsand another on the ground in a greenhouse. Plants were inoculated with the pathogenicbacteria and the reflectance spectrum of the apical leaflet of two leaves per plant wereobtained before symptoms expression;several spectral indices were calculated from thereflectance spectra. Three indices, of the shortwave-infrared zone, allowed the detectionof bacterial canker inoculated plants in a fast and non-destructive way, up to one weekbefore symptoms were visible: Normalized Difference Water Index (NDWI), Simple Ratioof Water Index (SRWI) and Water Index 1 180 (WI1180). Our research demonstrates, forthe first time, the usefulness of spectral indices sensitive to water content for the identifi-cation of diseased plants. These indices arise as a promising tool for the early detection ofvascular plant diseases, that could be integrated into sustainable management plans.

1 Transcatheter aortic valve implantation in symptomatic severe aortic stenosis: where do we stand? Aortic stenosis occurs in 2%-9% of patients over the age of 65, the most common cause being degenerative.^([1,2]) The preferred treatment in symptomatic severe aortic stenosis(SAS) is surgical aortic valve replacement(SAVR), but in the elderly, the surgical risk can be greater than the benefit.([3]).

This study aims to compare the grain protein profile of four Brazilian cowpea cultivars (BRS Aracê, BRS Itaim, BRS Pajeú, and BRS Xiquexique) by two-dimensional electrophoresis (2-DE) and principal component analysis (PCA). 2-DE efficiently separate cowpea protein profiles, showing high homogeneity among the four cultivars. In addition, the principal component analysis indicated that there is a difference in abundance of proteins among the cultivars. The cultivars BRS Aracê and BRS Xiquexique, both biofortified in iron and zinc, were separated from the cultivars BRS Itaim and BRS Pajeú. These results demonstrate that protein profiles can be used to discriminate cowpea varieties.

Diabetes mellitus is an important risk factor for coronary atherosclerosis and many patients present extensive coronary stenosis at coronarography. However, in patients with diabetes, endothelial and microvascular dysfunction also participate in chronic and acute myocardial ischemia. Although the majority of diabetic patients with myocardial infarction have angiographic evidence of significant coronary artery disease.

Objective To examine the relationship between Tpeak- Tend interval （Tpe） and Tpe/QT ratio with occurrence of ventricular premature beats （VPBs） and left ventricular remodeling in hypertension. Methods A total of 52 patients with mild to moderate essential hypertension were included, undergoing echocardiography and 24-hours Holter monitoring. Ventricular remodeling was assessed by left ventricular mass index （LVMI） using the Devereux formula and diastolic fimction by transmitral E and A wave velocities and E/A ratio. Tpe was measured in the precordial leads. The end of the T wave was set by the method of the tangent to the steepest descending slope of the T wave. Results Tpe and Tpe/QT in leads V2 （r = 0.33, P = 0.01; r = 0.27, P = 0.04 respectively） and V3 （r = 0.40, P = 0.002; r = 0.40, P = 0.003, respectively） correlated significantly with LVMI. A significant inverse relationship was observed between E/A ratio and QT （r = -0.33, P = 0.01）, Tpe in V3 （r = -0.39, P = 0.003） and Tpe/QT in V3 （r = -0.31, P = 0.02）. Tpe in V3, V5, mean Tpe and maximum Tpe with cut-offvalues of 60 ms, 59 ms, 62 ms and 71 ms, respectively, associated with the occurrence of ventricular premature beats. Conclusions The repolarization parameters Tpe interval and Tpe/QT ratio correlate with LVMI and indices of left ventricular diastolic function and show better predictive values than traditional parameters such as QT interval and QT dispersion. Lead V3 is the best lead for measuring Tpe and Tpe/QT. These ECG indices can therefore be used in clinical practice to monitor LV remodeling and predict occurrence of VPBs.
