Phosphatidylserine polarization is required for proper Cdc42 localization and for development of cell polarity. [PDF]

, 2010
We used genetically-encoded fluorescent probes to visualize the distribution of phosphatidylserine (PS) in live S. cerevisiae. The majority of the PS was found to reside in the cytosolic leaflet of the plasma membrane.

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 ...

Analysis of Axillary Bud Germination Regulatory Network in Sugarcane Based on Transcriptome and Weighted Gene Co-Expression Network Analysis

Plants
Axillary bud germination in sugarcane is a critical agronomic trait that directly determines seedling emergence and tillering capacity; however, its molecular regulatory mechanisms remain poorly understood.

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.

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.

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).

Implementation of a National Reference Laboratory for Buruli Ulcer Disease in Togo [PDF]

, 2013
Background: In a previous study PCR analysis of clinical samples from suspected cases of Buruli ulcer disease (BUD) from Togo and external quality assurance (EQA) for local microscopy were conducted at an external reference laboratory in Germany.

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 ...
