Vapour growth of silicon: growth anisotropy and adsorption [PDF]

open access: yes, 1991
The development of facets on hemispherical single crystal substrates is investigated for growth in a near-equilibrium hot-wall CVD system, in order to study the orientation dependence of silicon crystal growth as a function of gas phase parameters in the

A nanobody-based toolset to investigate the role of protein localization and dispersal in Drosophila

open access: yeseLife, 2017
The role of protein localization along the apical-basal axis of polarized cells is difficult to investigate in vivo, partially due to lack of suitable tools.

An Integrated Landscape Approach for Socially Inclusive Peatland Restoration

open access: yesJournal of Wetlands Environmental Management, 2020
Successful restoration and fire prevention in peat landscapes require full rewetting and permanent revegetation for optimal water retention. The ecological and socio-economic heterogeneity of these landscapes calls for integrated approaches based on ...

Decoding the dual role of autophagy in cancer through transcriptional and epigenetic regulation

open access: yesFEBS Letters, EarlyView.
Transcriptional and epigenetic regulation controls autophagy, which exerts context‐dependent effects on cancer: Autophagy suppresses tumorigenesis by maintaining cellular homeostasis or promotes tumor progression by supporting survival under stress. In this “In a Nutshell” article, we explore the intricate mechanisms of the dual function of autophagy ...

Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Vascular Endothelial Growth Factor Concentration in Brain of Rat Treated with Anaerobic Exercises [PDF]

open access: yes, 2015
Anaerobic exercise is a high-intensity exercise that needs quick energy supplies obtained in a very short time. However, this exercise may result in tissue hypoxia which is characterized by the increase of HIF-1α concentration.

Strain Engineering of Ferroelectric Domains in KxNa1−xNbO3 Epitaxial Layers

open access: yesFrontiers in Materials, 2017
The application of lattice strain through epitaxial growth of oxide films on lattice mismatched perovskite-like substrates strongly influences the structural properties of ferroelectric domains and their corresponding piezoelectric behavior.

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to
