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).

Answer:
The field of view is widest on the lowest power objective. When you switch to a higher power, the field of view is closes in. You will see more of an object on low power.

Microscope Notes
Answer:
The correct answer is c. the use of organisms to remove pollutants from the environment
Explanation:
Bioremediation is a process in which living organisms are involved in the treatment and removal of pollutants from the environment. Bacteria, fungi, and archaea are the organism that is widely used in bioremediation because they reproduce very fast.
These organism works on environmental pollutant and break them into simpler and harmless compound, for example, Alcanivorax or Methylocella Silvestris are the bacteria which is used to clean the oil spills in the oceans. Therefore the correct answer is c.
They walk on all fours , they can’t swim , shorter lifespan, extra chromosomes
Answer:
animals that eat only plants.
