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:
A dichotomous key is an important scientific tool, used to identify different organisms, based the organism’s observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.

Answer:
In a research there are two variables independent and dependent variable. independent variable is defined as the variable which is controlled and changed in a scientific experiment and evaluate the effects on the dependent variable while the variable which are tested and measured in experiment are called dependent variable.
When antibiotic is sprayed at one side of the petri dish, the bacterial growth on that side will eventually decrease in comparison to other side.
So, the independent variable in this experiment will be antibiotic because it is used to understand the growth of bacteria by decreasing their numbers and the dependent variable in this experiment will be bacteria as they vary according to the change in independent variable that is antibiotic.
