Mechanical Loading of Osteocytes via Oscillatory Fluid Flow Regulates Early‐Stage PC‐3 Prostate Cancer Metastasis to Bone

open access: yesAdvanced Biology, Volume 9, Issue 4, April 2025.
In this study, the authors show that osteocytes, mechanosensing cells embedded within bone, can indeed regulate prostate cancer cell extravasation through a blood vessel using a physiologically relevant tissue model. Specifically, it is shown that osteocytes modulate the expression of blood vessel cell adhesion molecules, affecting the frequency at ...

Ionizing Radiation Carcinogenesis [PDF]

open access: yes, 2012
Human exposure to ionizing radiation is a natural part of life on earth. These exposures occur every day from radiation associated with naturally occurring radionuclides in soil, air, and food, and also from cosmic rays. In addition, many people are exposed to dental and medical diagnostic procedures and therapy involving: x rays, gamma rays, charged ...

Development of Ternary Magnesium Alloys for Laser Powder Bed Fusion: Optimizing Oxide Layer Thickness

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

Ionization by Massive Young Clusters as Revealed by Ionization-Parameter Mapping [PDF]

open access: yesarXiv, 2014
Ionization-parameter mapping (IPM) is a powerful technique for tracing the optical depth of Lyman continuum radiation from massive stars. Using narrow-band line-ratio maps, we examine trends in radiative feedback from ordinary HII regions of the Magellanic Clouds and nearby starburst galaxies.

Ionizing Radiations in Entomology

open access: yes, 2015
Radiation in the form of particles (α or β particles and neutrons) or electromagnetic waves (gamma or X-rays) can induce biological effects in insect cells like in other living cells. Ionization and chemical damages to organic molecules can be caused directly (mostly by particulate types of radiation) or indirectly by free radicals.

A Novel Approach to Produce Metal–Metal Composites by Leveraging Immiscibility: Laser Powder Bed Fusion of Nanosilver‐Dispersed Titanium

open access: yesAdvanced Engineering Materials, EarlyView.
Incorporating nanosized silver into titanium for antimicrobial materials exploits the metastable miscibility gap between silver and titanium. Silver nanoparticles are synthesized via pulsed laser ablation in liquid. Silver addition refines the microstructure, increases hardness by 30%, and reduces Staphylococcus capitis microbial adhesion by 70%, with ...

Exposure to Mobile Phone Radiation Opens New Horizons in Alzheimer’s Disease Treatment

open access: yesJournal of Biomedical Physics and Engineering, 2013
Alzheimer’s disease, the most common type of dementia and a progressive neurodegenerative disease, occurs when the nerve cells in the brain die. Although there are medications that can help delay the development of Alzheimer’s disease, there is ...
