Constraints on the ionizing flux emitted by T Tauri stars

, 2005
We present the results of an analysis of ultraviolet observations of T Tauri Stars (TTS). By analysing emission measures taken from the literature we derive rates of ionizing photons from the chromospheres of 5 classical TTS in the range ~10^41-10^44 ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Monte Carlo study of nanoparticles effectiveness on the dose enhancement when irradiated by protons

AIP Advances, 2023
Recently, the nanomedicine field has experienced considerable growth in research. The use of nanoparticles to enhance dose in radiation treatment was proposed and their potential effects can be indicated using Monte Carlo calculations.

Public Awareness of Medical Imaging as a Source of Ionizing Radiation Exposure [PDF]

, 2017
Background. Biological effects of exposure to ionizing radiation (IR) are well known. Literature suggests most patients and physicians lack proficient understanding of risks associated with ionizing radiation.

Ly$\alpha$ Leaks and Reionization

, 2007
Ly$\alpha$ absorption spectra of QSOs at redshifts $z\simeq6$ show complete Gunn-Peterson absorption troughs (dark gaps) separated by tiny leaks. The dark gaps are from the intergalactic medium (IGM) where the density of neutral hydrogen are high enough ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Synergic Effect of TC99-m Gamma Radiation and Non-ionizing Radiation of Wi-Fi on Count, Morphology and Motility of Sperms in Rats: An Experimental Study

Iranian South Medical Journal, 2020
Background: Given the effects of ionizing radiation on biological tissues and their irreversible tissue damage, this project aimed to determine the synergic effect of TC99-m gamma radiation and non-ionizing radiation of Wi-Fi on sperm characteristics in ...
