Abstract Sleep apnea syndrome (SAS) is a disorder in which respiratory airflow frequently stops during sleep. Alterations electroencephalogram (EEG) signal are one of the physiological changes that occur apnea, and can be used to diagnose monitor sleep events. Herein, we proposed method automatically distinguish events using characteristics EEG signals order categorize obstructive (OSA) events, central (CSA) normal breathing Through use an Infinite Impulse Response Butterworth Band pass...

Evidence suggests that the arterial baroreceptors modulate pain. To examine whether cortical processing of nociception is modulated by natural variations in baroreceptor stimulation during cardiac cycle, peak-to-peak amplitudes N2–P2 pain-related potential and pain ratings were recorded response to noxious laser at different times cycle 10 healthy males. Significant occurred across with smaller midcycle, indicating was attenuated systole compared diastole. Pain did not vary cycle. These data...

Hypopnea refers to the state in which insufficient alveolar ventilation during night sleep decreases respiratory airflow by more than 50% of airflow. However, apnea is a serious event, such as complete cessation for 10 seconds. The occurrence hypopnea precursor events and two are closely connected. In this paper, we propose method based on combination discrete wavelet transform approximate entropy EEG signals detect events. For purpose, first, data preprocessing performed record set obtained...

Background With growing concerns about global population aging, comorbidity, and disability have emerged as key variables that influence the health of older adults in terms disease function. This study sought to examine impact comorbidity impairment using functional status indicators all-cause mortality adults. Hypertension, which was chosen indicator for disease, has greatest prevalence population. A total 15 self-reported chronic conditions were added grip strength a measure status. The...

To evaluate the therapeutic effects of auricular plaster therapy for obstructive sleep apnea syndrome (OSAS) and influence on sleeping structure.45 OSAS patients were randomly divided into a treatment group 30 cases control 15 comparison changes in parameters respiration at night.The significantly improved hypoventilation index, respiratory disturbance index other as well such time rate stage I II, waking rate.Auricular may show good OSAS, with advantages low cost less side effects.

Abstract Background and Aims Growing evidences have confirmed the effect of Sacubitril/Valsartan (SV) on hypertension heart failure espacially EFrHF in general population. However, data ARNI treatment maintenance hemodialysis (MHD) patients with EfpHF are lacking. The present study was conducted to assess efficacy safety sacubitril-valsartan HFpEF undergoing MHD. Method End-stage kidney disease (ESKD) MHD for more than 3 months New York Heart Association (NYHA) class II–IV ejection fraction...

The effects of smoking and nicotine on ultralate laser evoked potentials (LEPs), the EEG responses to C-fiber stimulation by a beam, were investigated in humans. Ultralate LEPs repeatedly measured two sessions, one after smoking, other abstinence from smoking. dominant frequency background alpha activity, heart rate venous plasma concentration also measured. peak-to-peak amplitude major components (N2 P2) was significantly correlated both with frequency. results suggest an arousal effect...

Good sleep quality is essential to our life and work. The two major challenges in evaluating are the scoring of stages apnea detection. In addition apnea, hypopnea also a respiratory event that occurs at an equal or even higher frequency compared apnea. However, phenomena not only different terms physical manifestation, there significant differences methods means clinical treatment. Therefore, this study we propose effective algorithm distinguish between events. We consider aspects feature...

The positioning algorithm of unmanned aerial vehicle (UAV) is one the key technologies in field autonomous flight. In this paper, absolute position calculated without global system (GPS) signals by using moving targets tracked onboard camera and relative between it UAV. method presented combined Meanshift target tracking calibration. According to obtained internal external parameters, image pixel coordinates UAV targets, world can be calculated. Multiple sets experimental data verifies that...

Cerebral infarct (CI) is a common disease of older adults, which increases the risk for cognitive impairment or dementia. CI-associated mild potential prodromal stage serious impairment. The grand total EEG (GTE) score rating scale clinical electroencephalography (EEG) analyses, useful in evaluation different types Sixty-five patients with CI underwent neuropsychological testing and resting state EEG. Spearman rank correlation analysis was used to investigate relationship between short...

Abstract Sleep apnea-hypopnea syndrome is a relatively common disease, characterized by repetitive reduction or cessation of respiratory airflow, which seriously affects sleep quality and in the long term, can lead to heart hypertension, diabetes, stroke. Polysomnography currently standard method for diagnosing apnea/hypopnea. However, accurate diagnosis be difficult due complex process multi-signals acquisition polysomnography. Instead, this paper presents novel automated fuzzy...

Abstract Sleep apnea is a kind of sleep disorder with high prevalence rate. It manifested as the abnormal stop breathing during and highly dangerous to human health. The purpose this research find simple, effective feature extraction method that can able distinguish obstructive events, central normal events. Unlike conventional methods, illustrated in study used Infinite Impulse Response Butterworth Band pass filter divide Electroencephalogram (EEG) signal into 5, 7, 9 or 11 frequency...

Objective To investigate the mean values of carotid intima-media thickness (IMT) and change features according to gender,segments age groups in general Chinese population,and provide basis for health assessment ultrasound.Methods GE LOGIQ 7 ultrasound scanner was used measure IMT 743 healthy cases aged from 38 70 years old.Six segments(bilateral common artery,bilateral bulb,bilateral internal artery) were measured each case.All patients divided into 6 across 5 be one group.The group...
