OENO One, 1985 Les incisions annulaires provoquent une modification de la teneur en polyphénols des pépins. Les résultats obtenus avec une double incision suggèrent qu'il existe une compétition entre le métabolisme polyphénolique des pépins qui accumulent des tanins ...

Horticulture Research, 2018 The role of melatonin in the regulation of fruit ripening and the mechanism involved remain largely unknown. In “Moldova” grape berries, melatonin accumulated rapidly from onset of veraison, reached the maximum at 94 days after bloom (DAB) and then ...

Physical Review Letters, 2009 Supersymmetric black holes are characterized by a large number of degenerate ground states. We argue that these black holes, like other quantum mechanical systems with such a degeneracy, are subject to a phenomenon which is called the geometric or Berry's phase: under adiabatic variations of the background values of the supergravity moduli, the quantum

Berry phase in a non-isolated system
, 2003 We investigate the effect of the environment on a Berry phase measurement involving a spin-half. We model the spin+environment using a biased spin-boson Hamiltonian with a time-dependent magnetic field.

Metformin Impairs Breast Cancer Growth through the Inhibition of PRMT6
Advanced Science, EarlyView.Metformin has a biological activity against breast cancer. However, it is largely unknown about its precise therapeutic targets. Here, histone arginine methyltransferase PRMT6 is identified as a new anti‐cancer target for metformin. Metformin directly binds PRMT6 and inhibits its ability to catalyze histone H3R2 asymmetric dimethylation (H3R2me2a ...

Electron energy spectrum and the Berry phase in graphite bilayer
, 2007 We emphasize that there exist four Dirac-type points in the electron-energy spectrum of a graphite bilayer near the point K of its Brillouin zone. One of the Dirac points is at the point K, and three Dirac points lie nearby.

Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa
Advanced Science, EarlyView.This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...
