PURPOSE: Patients suffering from cardiovascular autonomic failure often develop neurogenic supine hypertension (nSH), i.e., high blood pressure (BP) in the supine position, which falls in the upright position owing to impaired autonomic regulation. A committee was formed to reach consensus among experts on the definition and diagnosis of nSH in the context of cardiovascular autonomic failure. METHODS: As a first and preparatory step, a systematic search of PubMed-indexed literature on nSH up to January 2017 was performed...

INTRODUCTION: Cardiovascular autonomic failure is commonly associated with Parkinson's disease (PD), affecting the daily lives of patients. Rotigotine was recently reported not to influence cardiovascular autonomic responses in contrast to other dopaminergic drugs. The effect of rotigotine on daily blood pressure (BP) fluctuations might reflect autonomic failure in patients with PD. METHODS: Twenty-five PD patients who were receiving rotigotine and 12 patients not receiving rotigotine were recruited...

Diverse taxa use Earth's magnetic field in conjunction with other sensory modalities to accomplish navigation tasks ranging from local homing to long-distance migration across continents and ocean basins. However, despite extensive research, the mechanisms that underlie animal magnetoreception are not clearly understood, and how animals use Earth's magnetic field to navigate is an active area of investigation. Concurrently, Earth's magnetic field offers a signal that engineered systems can leverage for navigation in environments where man-made systems such as GPS are unavailable or unreliable...

One of the main causes of amputations in patients with Diabetes Mellitus patients is a chronic diabetic foot ulcer. The authors present a clinical case and discussion of a successful use of Granulocyte-Macrophages Colony Stimulating Factor (GM-CSF) treatment for the promotion of healing of a chronic diabetic foot ulcer. A 65 year-old woman was admitted to the Diabetes Center with complaints of a deep non-healing chronic foot ulcer for the last 18 months. At the examination a 5 cm ulcer on the plantar surface of the right foot was revealed...

BACKGROUND: In patients with kidney failure requiring hemodialysis (HD) treatment, intradialytic exercise (IDEX) has been advocated for its feasibility and effectiveness in improving important health outcomes. However, IDEX as an adjunct therapeutic strategy is infrequently implemented, in part due to potential risks of IDEX, especially in patients with chronic volume overload. This study was performed to evaluate the safety of IDEX performed at different time points by examining its effect on intradialytic cardiovascular hemodynamics...

BACKGROUND/OBJECTIVE: Recent studies have indicated that cardiac autonomic dysfunction is an early sign of cardiovascular impairment in rheumatoid arthritis (RA). Previous studies have mainly focused on resting assessments; however, analysis of heart rate (HR) responses to exercise might provide additional information on cardiac autonomic dysfunction in this disease. Thus, we aimed to assess the HR responses during and after a maximal graded exercise test in patients with RA and healthy controls (CONs)...

Human pluripotent stem cells (hPSCs) generate hematopoietic progenitor cells (HPCs) but fail to engraft xenograft models used to detect adult/somatic hematopoietic stem cells (HSCs) from donors. Recent progress to derive hPSC-derived HSCs has relied on cell-autonomous forced expression of transcription factors; however, the relationship of bone marrow to transplanted cells remains unknown. Here, we quantified a failure of hPSC-HPCs to survive even 24 hr post transplantation. Across several hPSC-HPC differentiation methodologies, we identified the lack of CXCR4 expression and function...

BACKGROUND: Although patients undergoing liver transplantation (LT) are frequently exposed to predisposing factors of atrial fibrillation (AF) such as autonomic imbalance, surgical stress, and elevated catecholamine levels, the occurrence of intraoperative AF (IOAF) has not been fully examined in LT candidates. METHODS: Data from 1059 patients who underwent adult LT from 2006 to 2010 were analyzed. Among patients with preoperative normal sinus rhythm, the incidence, prognosis, and detailed characteristics of newly developed IOAF were assessed...

Category learning performance is influenced by both the nature of the category's structure and the way category features are processed during learning. Shepard (1964, 1987) showed that stimuli can have structures with features that are statistically uncorrelated (separable) or statistically correlated (integral) within categories. Humans find it much easier to learn categories having separable features, especially when attention to only a subset of relevant features is required, and harder to learn categories having integral features, which require consideration of all of the available features and integration of all the relevant category features satisfying the category rule (Garner, 1974)...

In August 2003, 44 victims were poisoned by chemical warfare agents (CWAs) leaked from five drums that were excavated at a construction site in Qiqihar, Northeast China. The drums were abandoned by the former Japanese imperial army during World War II and contained a mixture of Sulfur mustard (SM) and Lewisite. We carried out a total of six regular check-ups between 2006 and 2014, and from 2008 we added neurological evaluations including neuropsychological test and autonomic nervous function test in parallel with medical follow-up as much as was possible...

Diagnosing degenerative forms of parkinsonism still relies on a thorough clinical assessment, which in Parkinson's disease involves the presence of an asymmetric bradykinesia with rest tremor and/or rigidity that respond substantially to levodopa. Conversely, atypical forms, including multiple system atrophy, progressive supranuclear palsy and corticobasal degeneration, exhibit additional features (cerebellar or pyramidal signs, early postural instability), a poor response to dopamine replacement therapy and a bad prognosis...

Duchenne muscular dystrophy (DMD) is a genetic recessive disorder with progressive muscle weakness. Despite the general muscle wasting, degeneration and necrosis of cardiomyocytes have been the main causes of morbidity and death in individuals with DMD. Cardiac failure is generally preceded by disturbances in heart rate variability (HRV), and non-invasive measurement of the autonomic nervous system has been an important tool to predict adverse cardiovascular events. Hence, the application of HRV to study autonomic modulation in DMD individuals, and the establishment of correlations between HRV and heart/lung diseases, age, and mortality will have the potential to improve quality of life and life expectancy of individuals with DMD...

Hyperpyrexia is a well-documented adverse effect of 3,4-methylenedioxymethamphetamine (MDMA) and is associated with a poor prognosis. There are currently limited published records of patients surviving a pyrexia of or greater than 43°C after MDMA intake. Rapid cooling and multiorgan support in an intensive care setting may offer patients the best chance of recovery. We present the case of a 16-year-old male who was admitted to our tertiary, adult intensive care unit (ICU) for unrecordable pyrexia (>43°C) after self-reported ecstasy intake...

We consider the design of a disagreement correction protocol in multi-vehicle systems. Vehicles broadcast in real-time vital information such as position, direction, speed, acceleration, intention, etc. This information is then used to identify the risks and adapt their trajectory to maintain the highest performance without compromising the safety. To minimize the risk due to the use of inconsistent information, all cooperating vehicles must agree whether to use the exchanged information to operate in a cooperative mode or use the only local information to operate in an autonomous mode...
