Under Pressure? A Study of Heart Rate and Heart-Rate Variability Using SmarTerp

open access: yesHermes, 2023
The results of a quasi-experimental, intra-subject study are reported on the effects of the use of SmarTerp on physiological stress levels of twelve second-year students of the MA in Interpreting at the University of Bologna during a simultaneous ...

Baroreflex sensitivity and heart-rate variability in prediction of total cardiac mortality after myocardial infarction

open access: yes, 1998
Summary Background Experimental evidence suggests that autonomic markers such as heart-rate variability and baroreflex sensitivity (BRS) may contribute to post-infarction risk stratification. There are clinical data to support this concept for heart-rate

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Ambulatory heart rate range predicts mode-specific mortality and hospitalisation in chronic heart failure [PDF]

open access: yes, 2015
Objective We aimed to define the prognostic value of the heart rate range during a 24 h period in patients with chronic heart failure (CHF).Methods Prospective observational cohort study of 791 patients with CHF associated with left ventricular systolic ...

HeartPy: A novel heart rate algorithm for the analysis of noisy signals

open access: yesTransportation Research Part F: Traffic Psychology and Behaviour, 2019
Heart rate data are often collected in human factors studies, including those into vehicle automation. Advances in open hardware platforms and off-the-shelf photoplethysmogram (PPG) sensors allow the non-intrusive collection of heart rate data at very ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Heart rate and use of beta-blockers in stable outpatients with coronary artery disease [PDF]

open access: yes, 2012
<p><b>Background:</b> Heart rate (HR) is an emerging risk factor in coronary artery disease (CAD). However, there is little contemporary data regarding HR and the use of HR-lowering medications, particularly beta-blockers, among ...

How heart rate variability affects emotion regulation brain networks

open access: yesCurrent Opinion in Behavioral Sciences, 2018
Individuals with high heart rate variability tend to have better emotional well-being than those with low heart rate variability, but the mechanisms of this association are not yet clear.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

open access: yesFEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

The Effect of Heart Rate on the Heart Rate Variability Response to Autonomic Interventions

open access: yesFrontiers in Physiology, 2013
Heart rate variability (HRV), the beat-to-beat variation in either heart rate (HR) or heart period (R-R interval), has become a popular clinical and investigational tool to quantify cardiac autonomic regulation. However, it is not widely appreciated that,
