Background: Amyloid-? accumulation was found to alter precuneus-based functional connectivity (FC) in mild cognitive impairment (MCI) and Alzheimer’s disease (AD) dementia, but its impact is less clear subjective decline (SCD), which combination with AD pathologic change theorized correspond stage 2 of the continuum 2018 NIA-AA research framework. Objective: This study addresses how amyloid pat...

Background: To explore the brain function regions characteristics of the acupoint combination, this study observed activity changes in the brain regions of healthy volunteers after acupuncture at both Taixi (KI3) and Taichong (LR3) (KI3 + LR3) and KI3 alone using resting-state functional magnetic resonance imaging (fMRI). Methods and Materials: 30 healthy volunteers were randomly allocated into...

Stimulation of macrophages by a variety of agents causes activation of mitogen-activated protein kinases (MAPKs). Activation of MAPKs by lipopolysaccharide involves CD14 and Toll receptors. Subsequent steps still remain to be explored. Tumor necrosis factor-alpha (TNF-alpha)-induced activation of MAPKs has been shown to involve the death domain proteins (TRADD, FADD, MADD) and TRAFs. Other mole...

In the present study, the brain's response towards near- and supra-threshold infrasound (IS) stimulation (sound frequency < 20 Hz) was investigated under resting-state fMRI conditions. The study involved two consecutive sessions. In the first session, 14 healthy participants underwent a hearing threshold-as well as a categorical loudness scaling measurement in which the individual loudness perc...

PURPOSE Arrhythmias can be treated by ablating the heart tissue in the regions of abnormal contraction. The current clinical standard provides electroanatomic 3-D maps to visualize the electrical activation and locate the arrhythmogenic sources. However, the procedure is time-consuming and invasive. Electromechanical wave imaging is an ultrasound-based noninvasive technique that can provide 2-D...
