Blood pressure is always given in the form of two numbers, one over the other, like a fraction. The systolic pressure is the upper number, and the diastolic pressure is the lower number. Both of these measurements are important. For example, a personâs BP reading may be 120/80 mmHg.
Chrysoprase, chrysophrase or chrysoprasus is a gemstone variety of chalcedony (a cryptocrystalline form of silica) that contains small quantities of nickel.Its color is normally apple-green, but varies to deep green. The darker varieties of chrysoprase are also referred to as prase.hrysoprase is cryptocrystalline, which means that it is composed of crystals so fine that they cannot be seen as distinct particles under normal magnification.
The PRPS1 gene provides instructions for making an enzyme called phosphoribosyl pyrophosphate synthetase 1, or PRPP synthetase 1. This enzyme helps produce a molecule called phosphoribosyl pyrophosphate (PRPP).PRPP is involved in making purine and pyrimidine nucleotides.n a milder form of PRS superactivity, the PRPS1 gene is overactive for reasons that are not well understood. PRPS1 gene overactivity increases the production of normal PRPP synthetase 1 enzyme, which increases the availability of PRPP. In both forms of the disorder, excessive amounts of purines are generated.
