People over age 60 may have an apparently normal creatinine blood level but still have a low GFR. The opposite can also be true, where the person may have a mildly low GFR without having kidney disease. The 24-hour urine collection method or another blood test called cystatin C can more ...
Sometimes called Dopplerultrasound, this is another way to check blood flow to the penis. It may be used along with the injection test. Your doctor takes a device that looks like a wand and holds it over your penis. It uses sound waves to create a video of your blood vessels so your ...
When the MagSifter is on, it pulls the nanoparticle-labeled CTCs from the blood sample and allows the rest of the blood to flow through the sifter. The CTCs pulled from the blood are then deposited into a flat array of tiny wells, each large enough for only one cell. Now the tumor ce...
A few of commercial anticoagulants have been identified and used for many years. Especially, anticoagulants are being used in medication for thrombotic disorders as well as formedical equipmentssuch asblood transfusions, test tubes andrenal dialysis. Moreover, heparin,coumarineand warfarin are used as...
Blood oxygen level-dependent (BOLD) fMRI of sleep provides unique opportunities to investigate brain function across a range of arousal states. fMRI relies on the blood flow (hemodynamic) response to local cortical circuit activity [1•], involving the so-called ‘neurovascular’ unit, in which...
First, we borrowed tools from the chaos theory to test for the SDIC27, and to demonstrate that blood flow, expressed by both exact solution and in vivo measurements, is not periodic. We have obtained Lyapunov exponents, as a test of SDIC associated with turbulence28, from the time series...
Manual auscultatory measurement of upper arm blood pressure (BP) with a mercury sphygmomanometer was the gold standard non-invasive test and mainstay clinical method to diagnose hypertension in the twentieth century [1, 2] This indirect measurement method, as well as automated BP methods, was use...

Specified p-values in the manuscript were calculated based on a non-parametric statistical analysis, so-called a Wilcoxon rank-sum test comparing RBC parameters between control and diabetes RBC groups, unless otherwise specified in the manuscript. In applying the test, red cell parameters of 40 RBC...
We propose an ultra-low-cost at-home blood pressure monitor that leverages a plastic clip with a spring-loaded mechanism to enable a smartphone with a flash LED and camera to measure blood pressure. Our system, called BPClip, is based on the scientific p
