A comprehensive embryonic staging series of the turtle Trachemys scripta

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Radiation Dose and Risk in the Radiological Investigation of Suspected Non‐Accidental Injury (NAI)

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study is a retrospective analysis of 362 skeletal surveys performed over a 5‐year period for children under 5 years of age for suspected non‐accidental injury. We present effective dose data and the associated risks of radiation exposure for initial and follow‐up examinations.

Overview of Diagnostic Ultrasound Safety

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,

Thoracic outlet syndrome: do we have clinical tests as predictors for the outcome after surgery?

open access: yesEuropean Journal of Medical Research, 2009
Objective Thoracic outlet syndrome (TOS) is a clinical phenomenon resulting from compression of the neurovascular structures at the superior aperture of the thorax which presents with varying symptoms.

Convergence Deficits in Myoclonus‐Dystonia Point to Cerebellar Impairment

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.
