Being unable to walk quickly can be frustrating and problematic, but it is a common issue, especially as people age. Noting the pervasiveness of slower-than-desired walking, engineers at Stanford University have tested how well a prototype exoskeleton system they have developed - which attaches around the shin and into a running shoe - increased the self-selected walking speed of people in an experimental setting.

Angiogenesis is a process of new vessel formation that is activated both in physiological (tissue repair, reproduction, etc.) and pathological (myocardial infarction, diabetic retinopathy, cancer, etc.) conditions. The process is carried out by endothelial cells and includes their proliferation, migration and arrangement in tubes. Angiogenesis regulation is precise and is mainly mediated by pro-angiogenic factors, such as vascular endothelial growth factor (VEGF), which in turn promote different signalling pathways leading to an increase of intracellular Ca2+ concentrations.

A medical smartwatch for researchers and healthcare providers to collect continuous and objective data from patients, while enabling health monitoring at scale
BOSTON, April 15, 2021 /PRNewswire/ EmbracePlus by Empatica has received the European CE mark as a Class lla medical device, for its ability to consistently provide quality physiological parameters to users. EmbracePlus is a medical smartwatch that continuously and remotely collects and processes physiological signals from the wrist, including pulse rate, pulse rate variability, blood oxygenation, respiratory rate, skin temperature, electrodermal activity, rest, and actigraphy data.
These data are continuously sent to a smartphone app, and transferred to the cloud for review and analysis by clinical researchers and healthcare professionals, through a single portal. Data can be streamed simultaneously from thousands of devices. This is possible both via E

High intensity interval training has become increasingly popular as it s a quick and effective way to improve health. This is all the more important as countries around the world emerge from lockdowns due to coronavirus and are looking for quick and easy way to exercise again.
Recently, researchers have been studying whether shorter variations of HIIT, involving as little as 4-min of high intensity exercise per session (excluding a warm up and cool down), also improve health.
A new review paper published in the
Journal of Physiology collates a decade s worth of research on the topic of this so-called low-volume high HIIT for health.
Medical College of Georgia investigators report a significant association between a faster decrease in resting heart rate from childhood to adulthood and a larger left ventricle, the heart s major pumping chamber, over a 21-year period in hundreds of individuals who were healthy at the start.
