In a new study, researchers demonstrate long-term, non-invasive monitoring of blood sodium levels using a system that combines optoacoustic detection with terahertz spectroscopy. The paper is ...

Intestinal absorption of cystine after oral cystine loading was markedly impaired in Type 1 and Type 2 cystinuric subjects, but only slightly abnormal in Type 3 cystinuric homozygotes.

After combining 100 μL of protein extract with 5 mL of the Bradford solution, the mixture was incubated for 5 min. Then, a UV-visible spectrophotometer was used to measure the absorbance at 595 nm, ...

A significant advancement in medical diagnostics is the non-invasive measurement of glucose. The effectiveness of photoacoustic (PA) signals produced from human tissue—which can be stimulated by ...

At 227 and 225 nm, graphs of absorbance vs oxygen concentration become increasing nonlinear (trending to smaller values) at higher oxygen concentration. The reason for the nonlinearity is not ...

This correlation enables the device to determine the concentration of the solute based on light absorption. To analyze an unknown sample, a calibration curve is first established. Known concentrations ...

Subsequently, the maximum and minimum UV absorbance of proteins vary as a function of amino acid composition. This supplies a rudimentary technique of measuring the purity of known proteins and amino ...

In assessing which model provided the best fit, visual analysis of the observed vs. predicted concentration graphs, residual plots, Akaike Information Criterion, %CV, and -2LL were considered. A ...

Our world right now is filled with competition and the stress that comes with it. While we run towards academic excellence and personal growth, it is normal to encounter obstacles. And in the run ...

Credit: Dr. Justin Tom. For data analysis, the graph of absorbance versus concentration can indicate how sensitive the system is when building a calibration curve. When a linear least squares ...
