Phytophthora and vascular plant species distributions along a steep elevation gradient

, 2021
A diverse Phytophthora community was detected in recent surveys conducted in alpine and subalpine areas, previously considered Phytophthora free. The current study was conducted to determine patterns of Phytophthora species richness and distribution ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Species richness of Orthoptera declines with elevation while elevational range of individual species peaks at mid elevation [PDF]

Species richness has been shown to decrease, and elevational range increase (the Rapoport effect), with elevation as a consequence of biotic and abiotic factors, but patterns are inconsistent across taxonomic groups.

Short-duration hypothermia completed prior to reperfusion prevents intracranial pressure elevation following ischaemic stroke in rats

, 2021
Reperfusion therapies re-establish blood flow after arterial occlusion and improve outcome for ischaemic stroke patients. Intracranial pressure (ICP) elevation occurs 18–24 h after experimental stroke.

Komunitas Burung pada Pegunungan Bawah dan Sub-Pegunungan Di Taman Nasional Gunung Halimun Salak

Journal of Natural Resources and Environmental Management, 2019
Bird diversity has been known to be affected by various factors, including elevational gradient. The objective of this study was to describe the bird community trend and its associated habitat conditions on lower mountain and sub-mountain areas.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Enhancing Urban Digital Elevation Models Using Automated Computer Vision Techniques

, 2010
In recent years Digital Elevation Models (DEM) gained much interest because of their high capability to give information about urban regions. DEM can be used for detailed urban monitoring, change and damage detection purposes.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Refinement of urban digital elevation models from very high resolution stereo satellite images

, 2009
Digital elevation models (DEM) of high resolution and high quality are required for many applications like urban modeling, readiness for catastrophes or disaster assessment.
