Relationship between the levels of abscisic acid in latent buds, in leaves and in internodes of Vitis vinifera L. cv. Merlot during the dormancy phase

OENO One, 1998
The levels of free and bound ABA (cis-ABA and cis-ABA-GE) were quantified weekly during the dormancy phase of three years in leaves, in latent buds and in internodes grapevine (Vitis vinifera L. cv.

Nano‐Engineered Titanium Implants Loaded With Gingival Fibroblasts‐Derived Microvesicles Enhance Early Osseointegration And Soft Tissue Attachment In Vivo

Advanced Healthcare Materials, EarlyView.
Our study showed that human primary gingival fibroblast–derived microvesicles on nano‐engineered titanium implants promote early osseointegration and soft‐tissue attachment in vivo. ABSTRACT Titanium dental implants require both reliable osseointegration and peri‐implant soft tissue seal formation to ensure long‐term success. While osseointegration has

Nematicidal activity of plant extracts against the root-knot nematode, Meloidogyne incognita [PDF]

, 2009
Nematicidal activity of extracts from plants was assayed against Meloidogyne incognita. In laboratory assays extracts from tobacco (Nicotiana tabacum L), clove (Syzygium aromaticum L), betelvine (Piper betle L), and sweet flag (Acorus calamus L) were ...

Small Extracellular Vesicles from Neural Cells: Physiological and Pathological Roles, and Potential in Neurodegenerative Therapy

Advanced Healthcare Materials, EarlyView.
Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...

Variation de la fertilité des bourgeons pendant le repos végétatif chez le cépage Merlot (Vitis vinifera L.) *

OENO One, 1977
Pendant le repos végétatif, les ébauches des inflorescences des bourgeons subissent une évolution physiologique qui se manifeste par une augmentation de leur poids moyen après le débourrement en conditions contrôlées.

Ocena efektywności przeciwpowodziowej kompleksu zbiorników wodnych w Zesławicach na rzece Dłubni [PDF]

Acta Scientiarum Polonorum. Formatio Circumiectus, 2018
Kompleks zbiorników Zesławice na rzece Dłubni zlokalizowany jest na terenie miasta Krakowa w pobliżu obszarów zabudowanych, co z jednej strony ogranicza dostępną pojemność rezerwy powodziowej, z drugiej zaś, narzuca wysoki poziom ochrony tych obszarów ...

Functional specialization of the yeast Rho1 GTP exchange factors [PDF]

, 2012
Rho GTPases are regulated in complex spatiotemporal patterns that may be dependent, in part at least, on the multiplicity of their GTP exchange factors (GEFs).

ETV2 Mediated Differentiation of Human Pluripotent Stem Cells Results in Functional Endothelial Cells for Engineering Advanced Vascularized Microphysiological Models

Advanced Healthcare Materials, EarlyView.
A robust method to generate functional human iPSC‐derived endothelial cells using inducible ETV2 expression. These cells self‐organize into stable, lumenized microvascular networks within microfluidic chips, surpassing conventional differentiation methods.

A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

Advanced Healthcare Materials, EarlyView.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...
