Studies upon the Physiological Action of Hematoporphyrin

THE RESULTS OF THESE OBSERVATIONS MAY BE BRIEFLY SUMMARIZED AS FOLLOWS: Feeding of hematoporphyrin to white mice over long periods of time produced no apparent changes in these animals and had no effect upon their sensitivity to light. Albino and slightly pigmented mice and rats injected with hematoporphyrin were protected from the rays of the sun by staining them a blue-black color with Verhoe...

The two-photon laser-induced fluorescence of the tumor-localizing photosensitizer hematoporphyrin derivative. Resonance-enhanced 750 nm two-photon excitation into the near-UV Soret band.

The tumor-localizing photosensitizer hematoporphyrin derivative (HPD) is shown to undergo a simultaneous two-photon excitation into the near-ultraviolet Soret band system upon intense laser irradiation at 750 nm, a spectral region where there is no significant HPD one-photon absorbance in aqueous solution. Subsequent to this excitation, internal conversion and vibrational relaxation occur, resu...

Investigating detailed educational aims Preschool in Iranian National Curriculum upon Islamic Theory of Action

Abstract: This researchr examines educational aims and goals of preschool stage in Iranian national curriculum. This examination is based on Islamic theory of action in childhood and carried out by using conceptual and comparative analysis methods. In a holistic view, it seems that these aims encounter 4 challenges. The first challenge is related to psychological requirements of children during...
