Hemoglobin-to-red blood cell distribution width ratio as a protective factor against coronary artery disease: a cross-sectional analysis of NHANES (2011-2018).

Background: Coronary artery disease (CAD) is the leading cause of death worldwide, and inflammation is a significant factor in its development. While the hemoglobin-to-red blood cell distribution width ratio (HRR), an indicator of inflammation, has been linked to various diseases, its association with CAD is not well established.

Methods: We conducted an analysis using data from the National Health and Nutrition Examination Survey (NHANES) spanning from 2011 to 2018.

Validation of the TMB-2296-BT blood pressure monitor in adults according to the ISO 81060-2:2018 + Amd.1:2020.

This study aimed to validate the accuracy of the test device (TMB-2296-BT) blood pressure (BP) monitor in adults according to International Standard Organization (ISO) 81060-2:2018 + Amd.1:2020 universal standard protocol, which is a digital monitor. Three trained observers used the same arm sequential method to compare the SBPs and DBPs measured by the test device with those measured by the reference device (mercury sphygmomanometer).

Validation of TMB-2285-BT wrist blood pressure monitor in general population according to the ISO 81060-2:2018 + Amd.1:2020 Protocol.

The objective of this study is to evaluate the accuracy of the wrist blood pressure (BP) monitor (TMB-2285-BT) in general population according to international standard of ISO 81060-2:2018+Amd.1:2020. The TMB-2285-BT BP monitor is an oscillometric device measuring BP from wrist.

Vacuum Based Gas Sensing Material Characterization System for Precise and Simultaneous Measurement of Optical and Electrical Responses.

Gas sensing performance characterization systems are essential for the research and development of gas sensing materials and devices. Although existing systems are almost completely automatically operated, the accuracies of gas concentration control and of pressure control and the ability to simultaneously detect different sensor signals still require improvement. In this study, a high-precision gas sensing material characterization system is developed based on vacuum technology, with the objective of enabling the precise and simultaneous measurement of electrical responses.
