Restless legs syndrome (RLS) is a chronic disorder causing clinically significant discomfort to approximately 3% of adults. Although RLS was first identified centuries ago, our understanding of this disorder, its causes, and its treatments is still evolving. In particular, our knowledge of the potential negative effects of RLS treatments, including dopaminergic augmentation, continues to expand. Augmentation, which refers to a paradoxical treatment-related increase in RLS symptoms, has been associated with all three dopamine agonists approved for the treatment of RLS - rotigotine, pramipexole, and ropinirole...

The structure and mechanical properties of polybutadiene (PB) film on bare and surface-modified carbon films were examined. There was an interfacial layer of PB near the carbon layer whose density was higher (lower) than that of the bulk material on the hydrophobic (hydrophilic) carbon surface. To glean information about the structure and mechanical properties of PB at the carbon interface, a residual layer (RL) adhering on the carbon surface, which was considered to be a model of "bound rubber layer," was obtained by rinsing the PB film with toluene...

The aim of this research is to apply an approach based on phase transfer entropy (PTE) and graph theory to study the interactions between the stereo-electroencephalography (SEEG) activities recorded in multilobar origin, in order to evaluate their ability to detect the epileptogenic zone (EZ) of temporal lobe epilepsies (TLE). Forty-three patients were included in this retrospective study. Five to sixteen (median = 12) multilead electrodes were implanted per patient, and, for each patient, a sub-set of between 10 and 32 (median = 22) bipolar derivations was selected for analysis...

Treating patients with restless legs syndrome (RLS) may pose a significant challenge to the clinician if those with intractable disease worsen with chronic treatment. Opioids are established as effective treatment for refractory RLS; however, some patients may be reluctant to try opioids because of the risk of dependency. Understanding the physician's duty to the patient through the framework of a shared decision-making model allows the neurologist to propose opioid therapy despite possible initial reluctance by the patient when the neurologist believes that this therapy is the most medically reasonable approach to optimizing the patient's well-being...

PURPOSE OF REVIEW: This article provides an update on six sleep-related movement disorders: restless legs syndrome (RLS), periodic limb movement disorder, sleep-related leg cramps, bruxism, rhythmic movement disorder, and propriospinal myoclonus, with an emphasis on RLS. RECENT FINDINGS: RLS is a common sensorimotor disorder that impairs quality of life. RLS is frequently comorbid to neurologic, psychiatric, vascular, and inflammatory diseases. Accumulating evidence implicates the pathophysiology of RLS as a state of dopamine dysfunction and iron deficiency that occurs on a background of genetic susceptibility conferred by 6 gene polymorphisms...

INTRODUCTION: Restless legs syndrome(RLS) is associated with sleep disorders. However, although sleep disturbance is prevalent in people with asthma, an insufficient number of studies have investigated the relationship between asthma and RLS. OBJECTIVES: We aimed to determine the extent of the presence of RLS, and the factors related to RLS, in people with asthma. METHODS: A total of 84 people with asthma and 51 healthy volunteers were enrolled...

A mechanism of cellular aging was proposed to be the gradual loss of certain cellular components that are insufficiently renewed. In an earlier study, multidrug resistance transporters (MDRs) were postulated to be such aging determinants during yeast replicative life span (RLS). Aged MDR proteins are asymmetrically retained by the aging mother cell and do not diffuse freely into the bud, whereas newly synthesized MDR proteins were thought to be deposited mostly in the bud prior to cytokinesis. In this study, we further demonstrate the proposed age asymmetry of MDR proteins in dividing yeast cells and investigated the mechanism that control diffusive properties of MDR proteins to maintain this asymmetry...

Natural and synthetic amphiphilic molecules including lipopeptides, lipopolysaccharides and glycolipids are able to induce defense mechanisms in plants. In the present work, the perception of two synthetic C14 rhamnolipids, namely Alk-RL and Ac-RL, differing only at the level of the lipid tail terminal group, have been investigated using biological and biophysical approaches. We showed that Alk-RL induces a stronger early signaling response in tobacco cell suspensions than does Ac-RL. The interactions of both synthetic RLs with simplified biomimetic membranes were further analyzed using experimental and in silico approaches...

OBJECTIVE: Restless legs syndrome (RLS) is a neurological sensorimotor disorder characterized by uncomfortable sensations in the legs. RLS often occurs as a comorbid condition. Besides an increased risk of iron deficiency, blood donors are considered to be generally healthy. Blood donors are therefore an ideal population for studying factors associated with RLS occurrence, herein the role of iron. It is suggested that RLS is linked to sex, age, low socioeconomic status, unhealthy lifestyle, and iron deficiency...

Restless legs syndrome (RLS) is a sensorimotor neurological disorder that is accompanied by the compelling urge to move one's legs, and unpleasant, disturbing sensations in the legs. Several neuropsychological studies have shown that RLS is associated with deficits in cognitive functions, such as attention, working memory, and frontal executive function, presumably due to abnormal frontal activities. However, the mechanism underlying the cognitive deficits in RLS patients is mostly unknown. To investigate the cortical origin of cognitive dysfunction in RLS, we analyzed the P2 and P3 event-related potential (ERP) components evoked by a visual oddball task using distributed cortical source localization via low-resolution brain electromagnetic tomography (LORETA) algorithm...

INTRODUCTION: Restless legs syndrome (RLS) is a prevalent sleep disorder affecting quality of life and is often comorbid with other neurological diseases, including peripheral neuropathy. The mechanisms related to RLS symptoms remain unclear, and treatment options are often aimed at symptom relief rather than etiology. RLS may present in distinct phenotypes often described as "primary" vs. "secondary" RLS. Secondary RLS is often associated with peripheral neuropathy. Nerve decompression surgery of the common and superficial fibular nerves is used to treat peripheral neuropathy...

Restless genital syndrome refers to excessive and persistent sensations of genital and clitoral arousal with the absence of conscious feeling of sexual desire. These sensations have been linked to symptoms of restless legs syndrome (RLS) or an overactive bladder. Restless genital syndrome may be related to small fiber sensory neuropathy of the dorsal nerve of the clitoris, so it more frequently occurs in women. The association with RLS suggests a possible dopaminergic mechanism. We report a case of a 74-year-old woman who presented restless genital symptoms every night in association with RLS symptoms...

Quantitative plasma viral load (VL) at 1000 copies /mL was recommended as the threshold to confirm antiretroviral therapy (ART) failure by the World Health Organization (WHO). Because of ongoing challenges of using plasma for VL testing in resource-limited settings (RLS), especially for children, this study collected 717 DBS and paired plasma samples from children receiving ART ≥1 year in Mozambique and compared the performance of DBS using Abbott's VL test with a paired plasma sample using Roche's VL test...

BACKGROUND: Restless legs syndrome (RLS) is a sensorimotor disorder. It can be idiopathic, associated to other diseases or to pharmacologic treatments. RLS has been reported to occur more frequently in migraine patients, but a clear pathogenetic link seems still under debate. We aimed to evaluate RLS prevalence in migraine, impact on sleep quality and the main clinical determinants of this association. METHODS: Migraine patients and age- and sex-matched controls were enrolled from 1(st) January 2011 to 30(th) December 2012...

Meis homeobox 1 (Meis1) is a transcription factor functioning in the development of the nervous system and the cardiovascular system. Both common and rare variants within the gene have been associated with restless legs syndrome (RLS), while its association with symptoms of insomnia has also been discovered recently. RLS is associated with sleep disturbances, and while Meis1 haploinsufficiency is one of the most promising strategies for an RLS animal model, sleep phenotyping of Meis1 knockout mice has never been conducted...
