Limitations in Predicting the Space Radiation Health Risk for Exploration Astronauts [PDF]

open access: yes, 2018
Despite years of research, understanding of the space radiation environment and the risk it poses to long-duration astronauts remains limited. There is a disparity between research results and observed empirical effects seen in human astronaut crews ...

The influence of timeshift on ciradian rhythm of sensitivity to X-irradiation in mice [PDF]

open access: yes, 1984
For two groups of male C3H mice an eastbound transmeridional flight was simulated by inducing a time shift of the L:D schedule of 8 hr. The assumed flight brought about a maxima) reduction of the daily light and dark span, respectively.

Upconversion Nanoparticles Embedded Photonic Contact Lens for Transepithelial Corneal Crosslinking Using Hyaluronate – Riboflavin Conjugate

open access: yesAdvanced Functional Materials, EarlyView.
A minimally invasive, transepithelial corneal cross‐linking (TE‐CXL) approach is presented using upconversion nanoparticles (UCNPs)‐loaded contact lenses (UCLs), after topical delivery of hyaluronate–riboflavin conjugates. The NIR‐to‐UV/blue light conversion by UCNPs in a UCL can activate riboflavin for TE‐CXL, resulting in the biomechanical strength ...

Prenatal Irradiation-Induced Hippocampal Abnormalities in Rats Evaluated Using Manganese-Enhanced MRI

open access: yesFrontiers in Neural Circuits, 2018
The aim of this study was to characterize hippocampal abnormalities in rats after prenatal x-ray irradiation using manganese-enhanced MRI (MEMRI). All radiation-exposed rat brains showed a reduced volume with prominent dilatation of lateral ventricles ...

Interobserver Reliability in Describing Radiographic Lung Changes After Stereotactic Body Radiation Therapy [PDF]

open access: yes, 2018
Purpose Radiographic lung changes after stereotactic body radiation therapy (SBRT) vary widely between patients. Standardized descriptions of acute (≤6 months after treatment) and late (\u3e6 months after treatment) benign lung changes have been proposed

Microplastics from Wearable Bioelectronic Devices: Sources, Risks, and Sustainable Solutions

open access: yesAdvanced Functional Materials, EarlyView.
Bioelectronic devices (e.g., e‐skins) heavily rely on polymers that at the end of their life cycle will generate microplastics. For research, a holistic approach to viewing the full impact of such devices cannot be overlooked. The potential for devices as sources for microplastics is raised, with mitigation strategies surrounding polysaccharide and ...

5,6,7,8-tetrahydroneopterin (NH4) Acts like an Endogenous Superoxide Dismutase

open access: yesPteridines, 1996
The protective effect of 5,6,7,8-tetrahydroneopterin (NH.) against radiation injury in mice was studied. (C57BL/6x A/J)F1 mice received whole body irradiation with a single fatal dose of 8.0 Gy X-ray.
