Cancer slope factors (CSF) are used to estimate the risk of cancer associated with exposure to a carcinogenic or potentially carcinogenic substance. A slope factor is an upper bound, approximating a 95% confidence limit, on the increased cancer risk from a lifetime exposure to an agent by ingestion or inhalation.
The CSF/serum glucose ratio, also known as CSF/blood glucose ratio, is a measurement used to compare CSF glucose and blood sugar. Because many bacteria metabolize glucose, and because the blood–brain barrier minimizes transversal, the ratio can be useful in determining whether there is a bacterial infection in the CSF. The normal ratio is 0.6 ...
Time-resolved 2D phase-contrast MRI with velocity encoding is the most common method for CSF analysis. [1] CSF Fluid Flow MRI detects back and forth flow of Cerebrospinal fluid that corresponds to vascular pulsations from mostly the cardiac cycle of the choroid plexus. Bulk transport of CSF, characterized by CSF circulation through the Central ...
Some experts say you should have two- to three-times your annual salary by age 40. So, if you earn $100,000 per year, you'll want to have between $200,000 and $300,000. Budgeting apps can help you ...
Measure the RBC index in cells/μL. Take the reciprocal (1/RBC index) to convert it to μL/cell. / = / 2. The 1 μL is only made of a proportion of red cells (e.g. 40%) with the rest of the volume composed of plasma.
One’s biological age, which measures the body’s physiological state, may help predict who is at risk for developing colon polyps, a known risk factor for colorectal cancer.
An online survey conducted by the Cleveland Clinic of 1,174 men 18 years or older, found that 72% of men would rather do household tasks, such as cleaning the bathroom or mowing the lawn, than see ...
