The intensities, observed under the different excitation wavelengths, of the B-Ge Raman peak at about 545cm(-1), which is due to the local vibrational mode of the substitutional B atoms in the Ge matrix, have been used to calibrate the optical absorption lengths in B-implanted Ge. Then, by using these calibrated

values, a very sharp correlation between the spectral features of the Ge-Ge Raman peak at similar to 300cm(-1) and the content of substitutional B atoms has been derived. Accordingly, a non-destructive approach, based on micro-Raman spectroscopy under different excitation wavelengths, is presented to estimate, at least at the lowest depths, the carrier concentration profiles selleck products from the spectral features of the Ge-Ge Raman peak.

“Oleanolic acid and related triterpenoids from olives modulate different signaling pathways, showing a wide range of pharmacological activities against inflammation, cancer or cardiovascular diseases. In particular, emerging evidences

reveal the potential of oleanolic acid to restore vascular disorders associated to cardiovascular risk factors, i.e. hypertension, obesity and diabetes, and atherosclerosis. During the previous years, in vitro and in vivo studies with these triterpenoids have positioned them as being mainly responsible for cardiovascular risk protection traditionally associated to olive oil. This review updates recent investigations in olive oil Smoothened Agonist manufacturer triterpenoids function related to cardiovascular diseases, as well as the underlying

mechanisms and structural implications. Important aspects of olive oil triterpenoids such as bioavailability and clinical perspectives on cardiovascular disorder are also extensively analyzed. All these investigations evidence the potential of triterpenoids from olive oil as a promising therapeutic strategy against vascular function, thus efficiently preventing the progression of cardiovascular diseases.”
“Drought is a major abiotic stress, limiting the survival and growth of young plants. However, selleck chemicals llc little is known about sex-dependent responses to drought at the proteome level. In this study, we carried out investigations on comparative proteomics, combined with physiological and organelle structure analyses, in males and females of Populus cathayana Rehd. Three-month-old poplar cuttings were treated at 30% of field capacity and at 100% field capacity as a control in a greenhouse for 40 days. Drought greatly inhibited plant growth, damaged the photosynthetic system and destructed the structures of chloroplasts, mitochondria and cellular membranes. However, males suffered less from the adverse effects of drought than did females. Using 2-DE, 563 spots were detected, of which 64 spots displayed significant drought effect and 44 spots displayed a significant sex by drought interaction effect.
