Relapsing–Remitting Multiple Sclerosis Is Associated With a Dysbiotic Oral Microbiome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by inflammation, demyelination, and neurological impairment. While the gut microbiota's role in MS is extensively studied, the association between the oral microbiota and MS remains underexplored, particularly in North American cohorts.

Improved resonance method for fatigue test of full-scale wind turbine blades

AIP Advances, 2022
To further reduce the power of exciter in the common fatigue testing methods and increase the testing frequency to decrease the fatigue testing time, this paper proposes an improved fatigue testing method—Tug Fatigue Testing system (TFTs). The advantages

Comparison of two methods of fatigue testing bone cement [PDF]

, 2009
Two different methods have been used to fatigue test four bone cements. Each method has been used previously, but the results have not been compared. The ISO 527-based method tests a minimum of 10 samples over a single stress range in tension only and ...

Decreased Serum 5‐HT: Clinical Correlates and Regulatory Role in NMJ of MG

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although 5‐Hydroxytryptamine (5‐HT) indirectly stimulates muscle contraction and participates in regulating Acetylcholine receptor (AChR) cluster homeostasis in cellular, animal, and clinical studies, evidence regarding its potential to modulate muscle contraction in myasthenia gravis (MG) remains limited.

Fretting Fatigue Behaviour of Alloy Steel in the Very High Cycle Region [PDF]

MATEC Web of Conferences, 2019
It is well known that fretting fatigue strength is much lower than the fatigue strength of smooth specimens and the fatigue limit disappears. Many studies on fretting fatigue have been reported but most of the studies have not cover fatigue properties in

Estimating the fatigue law of asphalt mixtures using a strain sweep test (EBADE test) [PDF]

, 2013
Fatigue characterization of asphalt mixtures is a very important issue. However, existing techniques to that end are expensive and time consuming. For that reason the asphalt technicians have been studying several different methods to reduce the testing ...

Nationwide Survey of Atopic Myelitis and Plexin D1‐Immunoglobulin G‐Related Pain

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To elucidate the features of plexin D1‐immunoglobulin (Ig)G‐associated neuropathic pain and its relationship to atopic myelitis (AM) in a nationwide Japanese survey. Methods A preliminary survey questionnaire was sent to 1574 selected departments (neurology and pediatrics/pediatric neurology) to explore the numbers of AM and plexin ...
