A photoplethysmogram ( PPG) is an optically obtained plethysmogram that can be used to detect blood volume changes in the microvascular bed of tissue. [1] [2] A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. [3] A conventional pulse oximeter monitors the perfusion of blood to ...
Polypropylene glycol or polypropylene oxide is the polymer (or macromolecule) of propylene glycol. [1] Chemically it is a polyether, and, more generally speaking, it's a polyalkylene glycol (PAG) H S Code 3907.2000. The term polypropylene glycol or PPG is reserved for polymer of low- to medium-range molar mass when the nature of the end-group ...
A photolabile protecting group ( PPG; also known as: photoremovable, photosensitive, or photocleavable protecting group) is a chemical modification to a molecule that can be removed with light. PPGs enable high degrees of chemoselectivity as they allow researchers to control spatial, temporal and concentration variables with light.
Purpose. determines the amount of a type of sugar after a meal. A postprandial glucose (PPG) test is a blood glucose test that determines the amount of glucose in the plasma after a meal. [1] The diagnosis is typically restricted to postprandial hyperglycemia due to lack of strong evidence of co-relation with a diagnosis of diabetes. [1]

Akt/PKB signaling pathway. The Akt signaling pathway or PI3K-Akt signaling pathway is a signal transduction pathway that promotes survival and growth in response to extracellular signals. Key proteins involved are PI3K ( phosphatidylinositol 3-kinase) and Akt ( protein kinase B ). Initial stimulation by one of the growth factors causes ...
Crystal structure of Akt-2-inhibitor complexes. [2] Protein kinase B ( PKB ), also known as Akt, is the collective name of a set of three serine/threonine-specific protein kinases that play key roles in multiple cellular processes such as glucose metabolism, apoptosis, cell proliferation, transcription, and cell migration .
Specifications. PPG Wave 2.2 front panel. PPG's Wave series represents an evolution of its predecessor by combining its digital sound engine with analog VCAs and 24db per octave VCFs, featuring 8-voice polyphony; and by replacing its nontraditional series of push buttons and sliders with a control panel consisting of an LCD and a more familiar ...
