Faster RCNN‐based detection of cervical spinal cord injury and disc degeneration

Journal of Applied Clinical Medical Physics, 2020
Magnetic resonance imaging (MRI) can indirectly reflect microscopic changes in lesions on the spinal cord; however, the application of deep learning to MRI to classify and detect lesions for cervical spinal cord diseases has not been sufficiently ...

Hypertension, antihypertensive medications use and risk of age-related macular degeneration in California Teachers Cohort [PDF]

Journal of Human Hypertension, 2019
Sustained and inadequately controlled hypertension can promote the development of age-related macular degeneration (AMD) through multiple biologic pathways. Epidemiologic studies of high blood pressure, antihypertensive therapies, and the risk of AMD thus far have been inconclusive. However, few studies evaluated risks according to the use of different

Dysphagia and Mortality Risk in Individuals With Primary Progressive Apraxia of Speech

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Individuals with primary progressive apraxia of speech (PPAOS) often develop parkinsonism and dysphagia. To evaluate the clinical correlates and impact of dysphagia in this population, we compared enrollment visit data between individuals with (n = 12) versus individuals without (n = 44) dysphagia symptoms.

Proton wave function in a water molecule: Breakdown of degeneration caused by interactions with the magnetic field of a Magnetic Resonance Imaging device [PDF]

arXiv, 2021
The concept of a Magnetic Resonance Imaging (MRI) device is based on the emission of radio waves produced by the protons of the hydrogen atoms in water molecules when placed in a constant magnetic field after they interact with a pulsed radio frequency (RF) current. When the RF field is turned on, the protons are brought to a spin excited state.

KIF5A p.Pro986Leu Risk Variant and Accelerated Progression of Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This study explored the impact of KIF5A rs113247976 (p.Pro986Leu), a risk allele for amyotrophic lateral sclerosis (ALS), on phenotypic variability in two Italian ALS cohorts (discovery, n = 865; replication, n = 1174). The minor allele (T) frequency was 0.015.

Longitudinal naming and repetition relates to AD pathology and burden in autopsy‐confirmed primary progressive aphasia

Alzheimer’s & Dementia: Translational Research & Clinical Interventions, 2021
Introduction In primary progressive aphasia (PPA) patients with autopsy‐confirmed Alzheimer's disease (AD) or frontotemporal lobar degeneration (FLTD), we tested how the core clinical features of logopenic PPA—naming and repetition—change over time and ...

Bio-medical degeneration in Britain, 1850-1914: theory and evidence

, 2022
During the second half of the nineteenth century leading to the First World War, a belief emerged that European populations were manifesting a process of physical and biological decline. This belief was inspired by social changes caused by industrialization and urbanization and by the apparent rationales of evolutionary biology, which appeared to place
