Acute respiratory failure (ARF) is defined as a sudden malfunction in the ability of respiratory system to maintain adequate gas exchange. Acute hypercapnic respiratory failure develops as a result of ventilation deficiency and it is defined as an increase of PaCO2 above 45 mmHg. Myasthenia Gravis (MG) is a sporadically developing auto-immune deficiency where the neuro-muscular transmission is affected and it is one of the important reasons for neurologically-induced respiratory distress. Here, we report a case of a 75-year-old male patient previously undiagnosed MG, who presented with ARF...

Kumamoto Earthquakes in 2016 severely affected medical circumstances and condition of each patient with neuro-muscular diseases, in addition to having destroyed life circumstances of local residence. Number of neuro-muscular disease patients admitted to the Department of Neurology, Kumamoto University, the only university hospital in the prefecture, increased approximately twice compared to usual years. Most of the related facilities were able to admit emergency patients with neuro-muscular diseases although the hospital buildings were damaged in various degrees...

OBJECTIVE: To investigate the effect of a neuro-muscular exercise (NEMEX) therapy program compared with instructions in optimized analgesics and anti-inflammatory drug use (PHARMA), on measures of knee-joint load in people with mild to moderate knee osteoarthritis (OA). We hypothesized that knee joint loading during walking would be reduced by NEMEX and potentially increased by PHARMA. DESIGN: Single-blind, RCT comparing NEMEX therapy twice a week with PHARMA. Participants with mild-to-moderate medial tibiofemoral knee OA were randomly allocated (1:1) to one of two 8-week treatments...

Muscle contractures are common in patients with central motor lesions, but the mechanisms responsible for the development of contractures are still unclear. Increased or decreased neural activation, protracted placement of a joint with the muscle in a short position and muscle atrophy have been suggested to be involved, but none of these mechanisms are sufficient to explain the development of muscle contractures alone. Here we propose that changes in tissue homeostasis in the neuro-muscular-tendon-connective tissue complex is at the heart of the development of contractures, and that an integrated physiological understanding of the interaction between neural, mechanical and metabolic factors, as well as genetic and epigenetic factors, is necessary in order to unravel the mechanisms that result in muscle contractures...

The nicotinic acetylcholine receptor (nAChR) gene family encodes for subunits of acetylcholine gated ion channels. These receptors are expressed widely and have many functions: They mediate excitation at neuro-muscular junctions. In the central nervous system nAChRs have been implicated in memory, cognition, and addiction. And in non-excitatory cells they regulate differentiation, proliferation and inflammatory responses. The CHRNA7 gene encodes for the a7 nAChR subunit that assembles into a homomeric receptor having unusual properties...

BACKGROUND: Serotonin syndrome is a toxic state, caused by serotonin (5HT) excess in the central nervous system. Serotonin syndrome's main feature is neuro-muscular hyperexcitability, which in many cases is mild but in some cases can become life-threatening. The diagnosis of serotonin syndrome remains challenging since it can only be made on clinical grounds. Three diagnostic criteria systems, Sternbach, Radomski and Hunter classifications, are available. Here we test the validity of four assumptions that have become widely accepted: (1) The Hunter classification performs clinically better than the Sternbach and Radomski criteria; (2) in contrast to neuroleptic malignant syndrome, the onset of serotonin syndrome is usually rapid; (3) hyperthermia is a hallmark of severe serotonin syndrome; and (4) serotonin syndrome can readily be distinguished from neuroleptic malignant syndrome on clinical grounds and on the basis of medication history...

Detection of neuro-muscular fatigue in strength training is difficult, due to missing criterion measures and the complexity of fatigue. Thus, a variety of methods are used to determine fatigue. The aim of this study was to use a principal component analysis (PCA) on a multifactorial data-set based on kinematic measurements to determine fatigue. Twenty participants (strength training experienced, 60% male) executed 3 sets of 3 exercises with 50 (12 repetitions), 75 (12 repetitions) and 100%-12 RM (RM). Data were collected with a 3D accelerometer and analysed by a newly developed algorithm to evaluate parameters for each repetition...

Radial artery catheterization results in local vascular injury to the artery and at times subsequent arterial occlusion, yet even in patients with abnormal collateral testing ischemic hand injury remains essentially unseen. Careful serial examinations of neuro-muscular function of the hand in patients undergoing transradial catheterization demonstrate that even in the case of radial occlusion and an abnormal collateral test, hand function is not altered after the procedure. While radial artery occlusion may not result in functional ischemic findings, the occlusion itself results in lost future opportunity for vascular access or conduit use and further understanding on how to prevent this sequalae continues to be a priority...

Herbal products containing Korean Angelica gigas Nakai (AGN) root extract are marketed as dietary supplements for memory enhancement, pain killing, and female menopausal symptom relief. We have shown the anticancer activities of AGN supplements in mouse models. To facilitate human anticancer translational research, we characterized the tissue distribution of AGN marker pyranocoumarin compounds decursin (D) and decursinol angelate (DA) ([Formula: see text]% in AGN) and their metabolite decursinol (DOH), assessed the safety of sub-chronic AGN dietary exposure in mice, and explored its impact on plasma aqueous metabolites and the prostate transcriptome...

Understanding the passive or non-passive behavior of the neuro-muscular system is important to design and control robots that physically interact with humans, since it provides quantitative information to secure coupled stability while maximizing performance. This has become more important than ever apace with the increasing demand for robotic technologies in neurorehabilitation. This paper presents a quantitative characterization of passive and non-passive behavior of the ankle of young healthy subjects, which provides a baseline for future studies in persons with neurological impairments and informs future developments of rehabilitation robots, such as exo-skeletal devices and powered prostheses...

Amyotrophic lateral sclerosis (ALS) is a progressive neuro-muscular disease characterized by motor neuron loss. MEF2D and MEF2C are members of the myocyte enhancer factor 2 family (MEF2), a group of transcription factors playing crucial roles both in muscle and in neural development and maintenance; for this reason, a possible involvement of MEF2 in ALS context has been investigated. Since the transcriptional activity of each tissue specific MEF2 isoform is conserved in different cell types, we chose to assess our parameters in an easily accessible and widely used experimental tool such as peripheral blood mononuclear cells (PBMCs) obtained from 30 sporadic ALS patients (sALS), 9 ALS patients with mutations in SOD1 gene (SOD1+) and 30 healthy controls...

Acousto-electric interaction signal (AEI signal) resulting from interaction of acoustic pressure wave and electrical current field has received recent attention in biomedical field for detection and registration of bioelectrical current. The signal is very of small value and brings about several challenges when detecting it. Several observations has been done in saline solution and on nerves and tissues under controlled condition that give optimistic indication about its utilization. Ultrasound Current Source Density Imaging (UCSDI) has been introduced, that uses the AEI signal to image the current distribution...

Studying (neuro)muscular disorders is a major topic in biomedicine with a demand for suitable model systems. Continuous cell culture (in vitro) systems have several technical advantages over in vivo systems and became widely used tools for discovering physiological/pathophysiological mechanisms in muscle. In particular, myoblast cell lines are suitable model systems to study complex biochemical adaptations occurring in skeletal muscle and cellular responses to altered genetic/environmental conditions. Whereas most in vitro studies use extensively characterized murine C2C12 cells, a comprehensive description of an equivalent human cell line, not genetically manipulated for immortalization, is lacking...

Human upright posture is maintained by postural movements, which can be quantified by "principal movements" (PMs) obtained through a principal component analysis (PCA) of kinematic marker data. The current study expands the concept of "principal movements" in analogy to Newton's mechanics by defining "principal position" (PP), "principal velocity" (PV), and "principal acceleration" (PA) and demonstrates that a linear combination of PPs and PAs determines the center of pressure (COP) variance in upright standing...

Brain-computer interfaces (BCI) have been shown to be a promising tool in rehabilitation and assistive scenarios. Within these contexts, brain signals can be decoded and used as commands for a robotic device, allowing to translate user's intentions into motor actions in order to support the user's impaired neuro-muscular system. Recently, it has been suggested that slow cortical potentials (SCPs), negative deflections in the electroencephalographic (EEG) signals peaking around one second before the initiation of movements, might be of interest because they offer an accurate time resolution for the provided feedback...

Calcium is associated with various functions of clinical importance. Its unique distribution;low intracellular and high extracellular concentration, is crucial for the neuro-muscular function. Calcium is also indispensable for the vascular contraction and blood coagulation. Thus, circulating calcium concentration must be strictly maintained within a narrow range, for which parathyroid hormone(PTH), vitamin D, and calcitonin contribute. Food-derived protein-bound calcium must be first released in the acidic condition...

BACKGROUND: Foot ulceration is the main precursor to lower limb amputation in patients with type 2 diabetes worldwide. Biomechanical factors have been implicated in the development of foot ulceration; however the association of these factors to ulcer healing remains less clear. It may be hypothesised that abnormalities in temporal spatial parameters (stride to stride measurements), kinematics (joint movements), kinetics (forces on the lower limb) and plantar pressures (pressure placed on the foot during walking) contribute to foot ulcer healing...
