Activation of Molecular Oxygen by Electron‐Rich Materials for Sustainable Soil Remediation

open access: yesAdvanced Science, EarlyView.
Abundant molecular oxygen (O2) in nature can be utilized and activated by electron‐rich materials to generate reactive oxygen species for in situ engineering remediation of contaminated soil. The material types, activation mechanisms, and influencing factors are discussed in the research.

Neuroprotective effects of some creatine derivative compounds

open access: yesJournal of Biological Research, 2010
Some derivatives more lipophylic than creatine, thus theoretically being capable to better cross the blood-brain barrier, were studied for their neuroprotective effect in mouse hippocampal slices.

Climate warming, euxinia and carbon isotope perturbations during the Carnian (Triassic) Crisis in South China [PDF]

open access: yes, 2016
The Carnian Humid Episode (CHE), also known as the Carnian Pluvial Event, and associated biotic changes are major enigmas of the Mesozoic record in western Tethys.

Characterization and Reuse of Lithium‐ion Battery Cathode Material Recovered Through a Bacterial Process

open access: yesAdvanced Energy Materials, EarlyView.
A sustainable bacteria‐based lithium‐ion battery cathode recycling method is optimized using engineering biology. The resulting biomineralized manganese carbonate species is found to be easily converted into an electrode material, via simple calcination.

Actively decaying or just poorly preserved? Can we tell when plant and invertebrate remains in urban archaeological deposits decayed? [PDF]

open access: yes, 2004
We have recendy argued that poorly preserved delicate macrofossil remains of plants and invertebrates in near-surface deposits in York are in active decay, rather than being preserved in stasis, part-way down the decay trajectory.

Detecting Awareness in the Intensive Care Unit Using Functional Near‐Infrared Spectroscopy

open access: yesAnnals of Neurology, EarlyView.
Objective Signs of awareness after acute severe brain injury are critical for informing goals‐of‐care decisions, ranging from the continuation of aggressive life‐sustaining therapy to comfort‐focused end‐of‐life measures. However, awareness may go undetected in some critically ill patients when assessed using bedside behavioral neurological examination.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

open access: yesThe Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

open access: yesThe Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

Effect of Ethanol on the Expression of Two Fructokinases in Rice Seedlings

open access: yesPlant Production Science, 2014
Germination of rice (Oryza sativa L.) caryopses in the presence of exogenous ethanol (the end-product of alcoholic fermentation under anoxia) results in a decrease of coleoptile and root growth.

SARchaeological Prospection: Synthetic Aperture Radar for the Reconstruction and Mapping of Temperate Floodplain Environments

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Temperate river floodplains present a significant challenge for archaeologists, as cultural and palaeoenvironmental remains are often difficult to locate but can be exceptionally well preserved, especially where groundwater levels are high. In these alluvial environments, the deposition of thick, fine‐grained sediments has potential to deeply ...
