Osmometry is a method of determining the concentration of solute particles in a solution that add to the osmotic pressure. The flow of a solvent (in biological systems, water) through membranes that separate two solutions is regulated by osmotic pressure. The ability to choose molecules of various sizes and shapes …
C-Peptide (Connecting peptide) is the binding peptide cleaved in proinsulin insulin processing. Responsive immunoassays in blood and urine can easily detect it. Serum C-peptide is a particularly useful marker of endogenous insulin secretion (a synthetic insulin that does not contain C-peptide). A patient is being diagnosed with exogenous (injected) insulin …
Liver Function Tests (LFTs) are blood tests that provide critical insights into your liver’s health. These tests measure specific enzymes, proteins, and substances that indicate liver functionality and help detect liver diseases or damage early. In this article, we’ll explore the liver’s role in your body, the importance of LFTs, and …
The fecal occult blood test detects bleeding in the gastrointestinal tract in a simple, fast, and low-cost manner. Although the treatment is not definitive for colorectal cancer or any other disease, it is commonly used as a colorectal cancer screening test, and is a leading cause of cancer death. When …
The WNT signaling pathway was first discovered in colon cancer research and embryonic development studies of fruit flies (Drosophila melanogaster), frogs (Xenopus laevis), and other animals. Colorectal and other forms of cancers may be caused by abnormal activation of the WNT pathway. The bipartite transcription factor β-catenin/ Tcell factor (β-cat/TCF) …
