Differential heart rate reactivity and recovery after psychosocial stress (TSST) in healthy children, younger adults, and elderly adults: The impact of age and gender [PDF]
, 2018 In addition to numerous reports about psychophysiological stress responses to acute stressors, there are few data available on gender differences of stress-induced heart rate responses in multiple age groups applying the same psychological stressor ...

Circulation Research, 2016 In the current issue of Circulation Research , McCrory et al1 report on the association of heart rate recovery after simple orthostatic challenge—otherwise known as standing up—with all-cause mortality. The authors measured heart rate changes in the first 110 seconds after standing up in 4475 participants of an Irish population–based, cohort study ...

Influence of Active Recovery on Cardiovascular Function During Ice Hockey [PDF]
, 2015 Background: Ice hockey is a popular sport comprised of high-intensity repeated bouts of activity. Light activity, as opposed to passive rest, has been shown to improve power output in repeated sprinting and could potentially help to offset venous ...

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies
Advanced Engineering Materials, EarlyView.Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

Estimation of maximal oxygen consumption and heart rate recovery using the Tecumseh sub-maximal step test and their relationship to cardiovascular risk factors [PDF]
, 2017 BACKGROUND: Maximum aerobic capacity (VO2max) is associated with lower cardiovascular and total mortality. Step tests can be used to provide an estimate of (VO2max) in epidemiological or home-based studies.

Advanced Engineering Materials, EarlyView.The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.
