Progress in research on osteoporosis secondary to SARS‐CoV‐2 infection

Animal Models and Experimental Medicine, EarlyView.
This review explores the potential mechanisms, complications, risk factors, and future research directions related to osteoporosis secondary to SARS‐CoV‐2 infection. Key mechanisms include an imbalance between osteoclast and osteoblast activity driven by direct viral effects on bone, inflammation, hypoxia, dysregulation of noncoding RNAs, and metabolic

Adult Neurogenesis in the Subventricular Zone of Patients with Huntington's and Parkinson's Diseases and following Long‐Term Treatment with Deep Brain Stimulation

Annals of Neurology, EarlyView.
Objective Parkinson's and Huntington's diseases are characterized by progressive neuronal loss. Previous studies using human postmortem tissues have shown the impact of neurodegenerative disorders on adult neurogenesis. The extent to which adult neural stem cells are activated in the subventricular zone and whether therapeutic treatments such as deep ...

Pulmonary Arteriovenous Malformation and Embolic Myocardial Infarction in a Patient With Hereditary Hemorrhagic Telangiectasia

JACC: Case Reports, 2020
This report describes a case of embolic myocardial infarction secondary to a pulmonary arteriovenous malformation. Pulmonary arteriovenous malformations are rare and mostly congenital and are inherited as an autosomal dominant disorder known as ...

Longitudinal Proteomic Profiling of Cognition across an Aerobic Exercise Intervention

Annals of Neurology, EarlyView.
The physiological basis of cognitive decline remains largely uncharacterized. We identified a protein panel signature, in living humans, that correlates to improvement in neurocognition over a period of 5 years. Our signature is composed of complement proteins, coagulation cascade, and extracellular matrix regulators.

A Method for Imaging the Ischemic Penumbra with MRI using IVIM [PDF]

This work examines the hypothesis that intravoxel incoherent motion MRI (IVIM) can quantify local cerebral blood flow (qCBF), infarct volume, and define the ischemic penumbra for determination of the perfusion-diffusion mismatch (PWI/DWI) volume in a setting of acute ischemic stroke.

Cascaded Convolutional Neural Network for Automatic Myocardial Infarction Segmentation from Delayed-Enhancement Cardiac MRI [PDF]

arXiv, 2020
Automatic segmentation of myocardial contours and relevant areas like infraction and no-reflow is an important step for the quantitative evaluation of myocardial infarction. In this work, we propose a cascaded convolutional neural network for automatic myocardial infarction segmentation from delayed-enhancement cardiac MRI.

Acute pulmonary thromboembolism with high‐density emboli in the pulmonary artery detected on non‐enhanced computed tomography

Respirology Case Reports
Key message The presence of high‐density emboli in the pulmonary artery on non‐enhanced computed tomography (CT) has high diagnostic performance for acute central pulmonary thromboembolism. Acute pulmonary thromboembolism is usually diagnosed by contrast‐

The antiplatelet activity of Aspirin [PDF]

, 1999
The synthesis of aspirin in the late nineteenth century marked the development of what was to become the most widely used household analgesic in the twentieth century.
