Prior to therapy, a high PpIX fluorescence was observed in three patients; however, after iPDT, this fluorescence was entirely photobleached. These patients' viable tumor sections had high PpIX concentrations (mean PpIX uptake per tumor: 1.4-3.0 M).
<h3>Briefing:</h3>
However, no or just minimal PpIX uptake (0-0.6 M) could be seen in the remaining two cases. Strong PpIX uptake patients demonstrated therapeutic response and long-term clinical stabilization (no progression at 29, 30, and 36 months); the remaining two patients experienced early treatment failure (death after 3 and 9 months).
<h3>Describe fluorescence:</h3>
Two steps make up the chemical process of fluorescence first, a chemical fluorophore such a protein or carotenoid absorbs shorter-wavelength light (excitation), and then some of the absorbed energy is released as longer-wavelength light (emission).

Adults will live only a day or so, but the aquatic larvae lives for about a year
Explanation:
Answer:
The three lines of defense model enhances the understanding of risk management and control by clarifying roles and duties. The model provides guidance for the implemented structure and the assigned roles and responsibilities of parties to increase the effective management of risk and control
Explanation:
the first line of defence – functions that own and manage risk. the second line of defence – functions that oversee or specialise in risk management, compliance. the third line of defence – functions that provide independent assurance, above all internal audit.
Answer:
Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff. Nonpoint source pollution includes many small sources, like septic tanks, cars, trucks, and boats, plus larger sources, such as farms, ranches, and forest areas.
