Dataset related to the article "LITHOTRIPSY OF CALCIFIED AORTIC VALVE LEAFLETS BY A NOVEL ULTRASOUND TRANSCATHETER-BASED DEVICE"
2022
This record contains raw data related to the article “LITHOTRIPSY OF CALCIFIED AORTIC VALVE LEAFLETS BY A NOVEL ULTRASOUND TRANSCATHETER-BASED DEVICE” The increasing incidence of calcific aortic valve disease necessitates the elaboration of new strategies to retard the progression of the pathology with an innovative solution. While the increasing diffusion of the transcatheter aortic valve replacements (TAVRs) allows a mini-invasive approach to aortic valve substitution as an alternative to conventional surgical replacement (SAVR) in an always larger patient population, TAVR implantation still has contraindications for young patients. In addition, it is liable to undergo calcification with …

Upscaling leaf gas exchange measurements to the whole grapevine canopy: An update
2009
This review first revisits current knowledge about single-leaf function, viz. photosynthesis, chiefly in relation to environmental factors, that underscores the importance of multiple summer stresses. Emphasis is placed on the response different genotypes show under light and heat stress with or without soil-water shortage. Secondly, it tackles the thorny issue of extrapolating single-leaf readings to the whole-canopy level, with special reference to both methodological and physiological implications. Whole-canopy gas-exchange systems deliver and emphasise the usefulness of such an approach in achieving key research goals. One case in point is quantifying the amount and dynamics of canopy g…
Growth stage and conditions affect sorbitol:sucrose ratio in peach source and sink organs
2008
Along with sucrose, sorbitol represents the major photosynthetic product and the main form of translocated carbon in peach. In leaves, the ability to synthesize and accumulate sorbitol and sucrose increases with leaf age or distance from the apex until full maturity. Also, in the internodes of a growing shoot sorbitol:sucrose ratio (SOR:SUC) increases with distance from the apex. In mature leaves, SOR:SUC increases in response to fruit sink removal and water deficit, due mainly to sorbitol rather than sucrose accumulation. Data from ‘Encore’ peach show that SOR:SUC remains fairly constant around 2:1 from the leaf blade all the way to the fruit peduncle and drops sharply in the fruit flesh a…

Synthesis of active principles from the leaves of Moringa oleifera using S-pent-4-enyl thioglycosides
1998
Abstract α - l -Rhamnosides of 4-hydroxy-benzyl compounds with nitrile, carbamate, and thiocarbamate groups occurring in Moringa oleifera leaf extracts and the α - l -rhamnoside of anisaldehyde derivatives were synthesised. Electrophilic activation of S -pent-4-enyl thiorhamnosides was applied for the construction of glycosidic linkages.

The Influence of (2-Chloroethyl)trimethylammoniumchloride (CCC) on Growth and Photosynthetic Metabolism of Young Wheat Plants (Triticum aestivum L.)
1984
Summary The influence of (2-chloroethyl)trimethylammoniumchloride on growth and cell metabolism of Triticum aestivum var. Kolibri was investigated. CCC was added to the nutrient solution on the 11th day of development with a final concentration of 10 −2 mol·1 −1 . It immediately stopped root growth and showed a strong inhibitory influence on the growth of the leaves. Smaller and fewer cells accounted for the reduction in final leaf size of about 40 %. The content of soluble proteins and soluble reducing sugars were significantly increased in the treated leaves. CCC also exhibited a stimulating effect on the synthesis of RubPc-ase protein and the in vitro activity of this enzyme. In contrast…
Retrieval of chlorophyll content and LAI of crops using hyperspectral techniques: application to PROBA/CHRIS data
2008
Hyperspectral/multiangular data allow the retrieval of important vegetation properties at canopy level, such as the Leaf Area Index (LAI) and Leaf Chlorophyll Content. Current methods are based on the relationship between biophysical properties and retrievals from those spectral bands (from the complete hyperspectral/multiangular information) where specific absorption features are present within the considered spectral range. Furthermore, new sensors such as PROBA/CHRIS provide continuous hyperspectral reflectance measurements that can be considered as a continuous function of wavelength. The mathematical analysis of these continuous functions allows a new way of exploiting the relationship…
