CSF (cerebro-spinal fluid) is a clear fluid that surrounds the brain and spinal cord in the skull and spinal column.The body continually renews this fluid by producing and then absorbing it. Among other functions, it helps to support and cushion the brain and spinal cord. The analysis of CSF can be very helpful when diagnosing various neurological diseases including meningitis, encephalitis and CJD.
Cancer Slope Factors. factors (for inhalation and ingestion) that define the relationship between exposure doses and the likelihood of an increased risk of developing cancer compared with non-exposed controls. Usually derived from animal or occupational studies, cancer slope factors are used to calculate the exposure dose likely to result in one excess cancer case per one million persons exposed over a lifetime (70 years).
colony stimulating factors. types of growth factors that promote growth and division of blood-producing cells in the bone marrow. CSFs are naturally produced in the body. But extra amounts may be given as a treatment to reduce or prevent certain side effects of chemotherapy due to not having enough blood cells.
