On the conversion of dose to bone to dose to water in radiotherapy treatment planning systems

Physics and Imaging in Radiation Oncology, 2018
Background and purpose: Conversion factors between dose to medium (Dm,m) and dose to water (Dw,w) provided by treatment planning systems that model the patient as water with variable electron density are currently based on stopping power ratios.

The use of acoustics in space exploration

, 2007
In recent years increased attention has been paid to the potential uses of acoustics forextraterrestrial exploration. The extent to which acoustics per se is used in these studiesvaries greatly. First, there are the cases in which acoustics is simply the

Acoustic Communication for Medical Nanorobots

, 2012
Communication among microscopic robots (nanorobots) can coordinate their activities for biomedical tasks. The feasibility of in vivo ultrasonic communication is evaluated for micron-size robots broadcasting into various types of tissues.

At the Pointy End of Mechanobiology: AFM for Transient Biomechanical Analysis

Advanced Healthcare Materials, EarlyView.
Stem cell mechanosensitivity governs lineage commitment through mechanotransduction, but capturing these transient changes in living cells remains challenging. Advanced atomic force microscopy enables high‐resolution analysis of mechanical properties, real‐time protein distribution, and gene expression, offering fresh insights into cell‐environment ...

In vitro antagonist activity of cedar Trichoderma species against three cedarwood lignivorous fungi

Scientific African
Cedarwood lignivorous fungi cause significant damage to cedar groves. In Morocco, the losses of cedar wood are estimated at more than 30% due to these fungi, which cause two primary diseases known as M'jej and Saboune. In this study, we are interested in

Visualizing BDNF Transcript Usage During Sound-Induced Memory Linked Plasticity

Frontiers in Molecular Neuroscience, 2018
Activity-dependent BDNF (brain-derived neurotrophic factor) expression is hypothesized to be a cue for the context-specificity of memory formation. So far, activity-dependent BDNF cannot be explicitly monitored independently of basal BDNF levels. We used

Seeing inside the Body Using Wearable Sensing and Imaging Technologies

Advanced Healthcare Materials, EarlyView.
This review explores wearable technologies for noninvasive internal health monitoring. It categorizes approaches into indirect sensing (e.g., bioelectrical and biochemical signals) and direct imaging (e.g., wearable ultrasound and EIT), highlighting multimodal integration and system‐level innovation toward personalized, continuous healthcare.
