Assessment of Small Vessel Density Changes in Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalophy (CADASIL) by High‐Resolution Black‐Blood MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Direct assessments of cerebral small vessels in Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) remain a challenge. Purpose To investigate changes of cerebral small vessels in CADASIL using iso‐0.5 mm black‐blood MRI. Study Type Case control study.

Predicting Breath Hold Task Compliance From Head Motion

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Cerebrovascular reactivity reflects changes in cerebral blood flow in response to an acute stimulus and is reflective of the brain's ability to match blood flow to demand. Functional MRI with a breath‐hold task can be used to elicit this vasoactive response, but data validity hinges on subject compliance.

Sonographic Anatomy and Imaging of the Extracranial Component of the Hypoglossal Nerve (CNXII)

Journal of Medical Radiation Sciences, EarlyView.
The hypoglossal nerve (HN) provides motor innervation to tongue muscles responsible for tongue movement, speech, mastication, swallowing, respiratory functions and management of oral secretions. The intracranial component of the HN can be demonstrated on magnetic resonance imaging and the extracranial component can be demonstrated with sonographic ...

XANES spectroscopy proofs pH‐dependent P sorption partitioning to Fe oxyhydroxides versus montmorillonite in acidic soils

Journal of Plant Nutrition and Soil Science, EarlyView.
Abstract Background Fe and Al oxyhydroxides are well‐known phosphorus (P)‐retaining minerals in soils. Little information is available regarding the relevance of clay minerals for the sorption of P in mixed oxyhydroxide–clay mineral systems and pH effects on P sorption partitioning.

Hell's Itch: An Acute Reaction to Sunburn Exposure

JEADV Clinical Practice, EarlyView.
ABSTRACT Hell's itch is a neurocutaneous dysesthesia following sunburn that is underreported in scientific literature despite considerable discussion online. ‘Hell's itch’ describes an acute, uncontrollable itch with intense stabbing pain several days post‐sunburn and often follows an inciting event such as water exposure.
