The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...

Advancing Age Modulates Associations Between Cognitive Impairment and Brain Volumes in Early MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Cognitive impairment is common in multiple sclerosis (MS), but manifestations following the first demyelinating event are relatively unexplored. We investigated cross‐sectional associations between magnetic resonance imaging (MRI)–derived brain volumes and the presence of cognitive impairment outcomes five years after the first ...

Tensions between Access and Control in Makerspaces

Proceedings of the ACM on Human-Computer Interaction, 2021
Makerspaces have complex access control requirements and are increasingly protected through digital access control mechanisms (e.g., keycards, transponders). However, it remains unclear how space administrators craft access control policies, how existing technical infrastructures support and fall short of access needs, and how these access control ...

Bolt Tension Control with a Direct Tension Indicator

Engineering Journal, 1973
Achieving the minimum required bolt tension in a high strength bolted friction-type joint is a primary factor, since the slip resistance of the joint is dependent on the bolt tension. Current specifications require that high strength structural bolts be tightened to at least 70 percent of the minimum required tensile strength.

Tension Controllers for a Strip Tension Levelling Line

2017
Strip material processed in continuous production lines causes a mechanical coupling among tension rolls driven by a multi-motor drive system. Thus, the drives are mutually mechanically coupled and influenced in their operation. One of the key techniques, to guarantee the output product quality in the fibre, paper, plastic and metal plating industries,

Tension control for musculospastic pain

Psychosomatics, 1980
Abstract This report describes the author's experience in applying a basic understanding of muscle psychophysiology to the treatment of pain caused by muscle spasm. Training patients in muscle relaxation has proved particularly helpful in treating the temporomandibular joint syndrome.

Allosteric Control through Mechanical Tension

Physical Review Letters, 2005
Conformational changes of proteins modulate their function. In allosteric control, the conformational change is induced by the binding of a signaling molecule. Here we insert a "molecular spring" on the enzyme guanylate kinase, to control the conformation of this protein. The stiffness of the spring can be varied externally, which allows one to exert a
