Emission of floral volatiles is facilitated by cell-wall non-specific lipid transfer proteins

open access: yesNature Communications, 2023
Volatile compounds to be released from the plant cell to the atmosphere must cross the cell wall. Here the authors show that cell-wall localized non-specific lipid transfer proteins facilitate the diffusion of volatiles across the hydrophilic cell wall.

Depth-Resolved Attenuation Mapping of the Vaginal Wall under Prolapse and after Laser Treatment Using Cross-Polarization Optical Coherence Tomography: A Pilot Study

open access: yesDiagnostics, 2023
Vaginal wall prolapse is the most common type of pelvic organ prolapse and is mainly associated with collagen bundle changes in the lamina propria.

Improving the wall thinning of the transition shoulder with anti-wedge upset rolling in cross wedge rolling hollow parts

open access: yes工程科学学报, 2016
Wall thinning occurs at transition shoulders in cross wedge rolling (CWR) hollow parts without a mandrel, which will reduce the mechanical strength of the parts, so improving the wall thickness of the shoulder must be resolved.

Effects of the Aspect Ratio and Cross-Sectional Area of Rectangular Tubes on Packing Characteristics of Mono-Sized Pebble Beds

open access: yesEnergies, 2023
The packing characteristics of a pebble bed are essential to understand the heat- and mass-transfer processes occurring within a granular system. Therefore, the packing characteristics of rectangular prismatic pebble beds randomly packed with mono-sized ...

Phenolic compounds as cross-links of plant derived polysaccharides

open access: yesCzech Journal of Food Sciences, 2004
Plant cell wall polysaccharides are partially cross-linked via phenolic compounds. As shown in the past, the most important phenolic compounds to cross-link plant cell-wall polysaccharides are ester-linked ferulic acid dimers, but p-coumarate dimers were

Cross bore size and wall thickness effects on elastic pressurised thick cylinders

open access: yesInternational Journal of Mechanical and Materials Engineering, 2019
Three-dimensional finite element analyses were performed on closed-ended thick-walled cylinders with a radial cross bore under internal pressure. The aim of this study was to determine the behaviour of the hoop stress as well as to establish the optimal ...

Adventitial Collagen Cross-Linking by Glutaraldehyde Reinforcing Human Saphenous Vein - Implication for Coronary Artery Bypass Grafting [PDF]

open access: yesBrazilian Journal of Cardiovascular Surgery, 2022
Introduction: A weak venous wall is one of the major reasons contributing to vein graft failure after coronary artery bypass grafting (CABG). We investigated whether adventitial collagen cross-linking by glutaraldehyde reinforces venous wall, preserving ...
