Cognitive output and physical activity levels fluctuate surrounding sleep. The ubiquitous digitization of behavior via smartphones is a promising avenue for addressing how these fluctuations occur in daily living. Here, we logged smartphone touchscreen interactions to proxy cognitive contrasted patterns on wrist-worn actigraphy. We found that both activities were dominated by diurnal (∼24 h) in...

Background: Dyslipidemia is considered an independent risk factor for coronary heart disease (CHD). In the present study, we examined lipid profiles and paraoxonase 1 (PON1) activity and atherogenic indexes status and the relationship of PON1 activity by high-density lipoprotein (HDL) and atherogenic indexes in CHD patients and healthy people. Methods: The aim of the study was to compare PON...

Background and Aims: Cardiac hypertrophy is a compensatory augmentation response of the heart due to pressure overload that can lead to heart failure. Carvacrol is considered as the major compound of many plants, that possesses strong antioxidant properties. The present study aimed to evaluate effect of carvacrol on catalase activity and mRNA expression following left ventricular hypertrop...

introduction: there are several technical features that make pet an ideal device for the noninvasive evaluation of cardiac physiology. organ motion due to respiration is a major challenge in diagnostic imaging, especially in cardiac pet imaging. these motions reduce image quality by spreading the radiotracer activity over an increased volume, distorting apparent lesion size and shape and reduci...

Recordings of membrane and field potentials, firing rates, and oscillation amplitude dynamics show that neuronal activity levels in cortical and subcortical structures exhibit infra-slow fluctuations (ISFs) on time scales from seconds to hundreds of seconds. Similar ISFs are salient also in blood-oxygenation-level dependent (BOLD) signals as well as in psychophysical time series. Functional con...

t-wave oversensing occurs when the counter starts giving dual beeps for every cardiac cycle instead of one. this usually happens when the monitoring lead displays a tall t wave, which is also sharp. r wave sensing algorithms of the devices do not sense t wave because the slow rate of the t wave is much less than that of the r wave. but the slow rate of t waves may change with time and also beca...

INTRODUCTION Novel approaches for the synthesis of gold nanoparticles (AuNPs) are of great importance due to its vast spectrum of applications in diverse fields, including medical diagnostics and therapeutics. Te presented study reports the successful AuNPs' synthesis using Artocarpus heterophyllus Lam. extract, and provides detailed characterization and evaluation of its antibacterial potentia...

A fundamental feature of the temporal organization of neural activity is phase-amplitude coupling between brain rhythms at different frequencies, where the amplitude of a higher frequency varies according to the phase of a lower frequency. Here, we show that this rule extends to brain-organ interactions. We measured both the infra-slow ( 0.05 Hz) rhythm intrinsically generated by the stomach – ...
