3e tunneling processes in a superconducting single-electron tunneling transistor [PDF]

, 1998
A current due to a tunneling event that involves three times the charge of an electron was observed in the current - voltage characteristics of a superconducting single-electron tunneling transistor. In this tunnel event, a Cooper pair tunnels through one tunnel barrier simultaneously with a quasiparticle that tunnels through a second tunnel barrier ...

Transthyretin amyloid cardiomyopathy in aortic stenosis patients scheduled for transcatheter aortic valve implantation

ESC Heart Failure, EarlyView.
Abbreviations: TAVI, transcatheter aortic valve implantation; ATTR‐CM, transthyretin cardiac amyloidosis. We aimed to diagnose occult ATTR‐CM in patients with severe aortic stenosis undergoing TAVI using bone scintigraphy. We verified a diagnosis of ATTR‐CM in 8 of 171 (4.7 %) consecutive aortic stenosis patients who underwent TAVI.

Carpal Tunnel Syndrome with Wrist Trigger Caused by Hypertrophied Lumbrical Muscle and Tenosynovitis

Case Reports in Orthopedics, 2015
We present a case of carpal tunnel syndrome involving wrist trigger caused by a hypertrophied lumbrical muscle with flexor synovitis. The case was a 40-year-old male heavy manual worker complaining of numbness and pain in the median nerve area. On active

Delays in diagnosis and treatment of ATTR cardiac amyloidosis: A real‐world data analysis

ESC Heart Failure, EarlyView.
Abstract Aims and Background Cardiac amyloidosis leads to functional cardiac impairment and heart failure. Transthyretin amyloid cardiomyopathy (ATTR‐CM) is the most common form. After initial suspicion, diagnosis involves imaging techniques, biopsy and genetic tests, prompting transthyretin stabilizer therapy to slow disease progression.

The Cinical Significance of the Palmaris Longus Tendon and Functional Superficial Flexor of the Little Finger in the Pathophysiology of Carpal Tunnel Syndrome

Medical Journal of The Islamic Republic of Iran, 2008
Background: The pathophysiology of carpal tunnel syndrome is associated with increased intracarpal canal pressure. Recently, palmaris longus has been introduced as an independent risk factor for the development of carpal tunnel syndrome.The  purpose of ...

Attention-Guided Discriminative Region Localization and Label Distribution Learning for Bone Age Assessment [PDF]

arXiv, 2020
Bone age assessment (BAA) is clinically important as it can be used to diagnose endocrine and metabolic disorders during child development. Existing deep learning based methods for classifying bone age use the global image as input, or exploit local information by annotating extra bounding boxes or key points.

Tunnel magnetoresistance in alumina, magnesia and composite tunnel barrier magnetic tunnel junctions [PDF]

, 2010
Using magnetron sputtering, we have prepared Co-Fe-B/tunnel barrier/Co-Fe-B magnetic tunnel junctions with tunnel barriers consisting of alumina, magnesia, and magnesia-alumina bilayer systems. The highest tunnel magnetoresistance ratios we found were 73% for alumina and 323% for magnesia-based tunnel junctions.

Novel three‐dimensional ECG algorithm for reliable screening for cardiac amyloidosis

ESC Heart Failure, EarlyView.
The present manuscript describes the derivation and validation of an algorithm for screening of cardiac amyloidosis using 3‐dimensional ECG. The algorithm is based on a ECG vector loop, acquired over the duration of 15 seconds using 4 electrodes. With this easy to perform method, we describe a high diagnostic accuracy for the detection of cardiac ...

Understanding central sensitization for advances in management of carpal tunnel syndrome [version 1; peer review: 3 approved]

F1000Research, 2020
Carpal tunnel syndrome is the most common nerve compression disorder of the upper extremity, and it is traditionally considered a peripheral neuropathy associated with a localized compression of the median nerve just at the level of the carpal tunnel ...

The Mayo ATTR‐CM score versus other diagnostic scores and cardiac biomarkers in patients with suspected cardiac amyloidosis

European Journal of Heart Failure, EarlyView.
Proposed algorithm to screen for transthyretin cardiac amyloidosis (ATTR‐CA). AL‐CA, immunoglobulin light‐chain cardiac amyloidosis; AMYLI, AMYLoidosis Index; AUC, area under the curve; IWT, increased wall thickness; LVEF, left ventricular ejection fraction; PYP, pyrophosphate.
