Age and Sex Differences in Heart Rate Variability and Vagal Specific Patterns – Baependi Heart Study
Global Heart, 2020 Background: Heart rate variability (HRV) is a noninvasive method for assessing autonomic function. Age, sex, and chronic conditions influence HRV. Objectives: Our aim was to evaluate HRV measures exploring differences by age, sex, and race in a sample ...

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Heart rate variability measurements and the prediction of ventricular arrhythmias.
, 2005 Heart rate variability (HRV) is the temporal variationbetween sequences of consecutive heartbeats. It is possible that HRV confers a survival advantage.In normal subjects, a variable heart rate is the normal physiological state.

Autism Research, EarlyView.ABSTRACT Irritability is a prevalent and impairing feature associated with autism, yet remains poorly understood, particularly in adults. Drawing heavily on insights translated from pediatric and transdiagnostic literatures, we propose that irritability in autistic individuals often reflects a psychophysiological stress or threat response, rooted in a ...

Cross-reactivity between HRV-A and HRV-C.
, 2013 (A) An example of strong cross-inhibition in HRVA34 and HRV-C3 double-positive sera. (B) An example of poor cross-inhibition between HRV-A34 and HRV-C3 observed in a minority of subjects who had high IgG1 titres to both HRV-A and HRV-C. The inhibition of

British Journal of Clinical Pharmacology, EarlyView.SGLT2 inhibitors and GLP‐1 receptor agonists modestly lower blood pressure across diverse patient populations, including those without diabetes. These effects appear largely independent of glycaemic control and offer additive value in high‐risk patients with overlapping comorbidities.
