Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows
IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

Blood pressure measurement on the cheek
Current Directions in Biomedical Engineering, 2016 In a large group of patients, it is impossible to measure blood pressure using an upper arm cuff. An alternative, non-invasive method of blood pressure measurement is required for patients with severe limb deformities or obesity, for amputees, and in the

British Journal of Pharmacology, EarlyView.Obesity is a chronic, relapsing, multisystem disease in which cardiometabolic risk arises from excess adiposity and progressive dysfunction of peripheral organs, ultimately disrupting endocrine and metabolic crosstalk among tissues. Within this network, sulphur‐based biology, centred on hydrogen sulphide and related reactive sulphur species, has ...

International Endodontic Journal, EarlyView.ABSTRACT Background Pulse oximetry is an accurate diagnostic method for assessing the condition of the dental pulp; however, the normal oxygen saturation levels for each tooth type are yet to be clearly defined. Objectives This systematic review and meta‐analysis aims to answer the question: What are the reference values for pulse oximetry testing in ...
