The aim of this study was to shown that the photosensitizer in photodynamic therapy (PDT) can contribute to the dark toxicity and phototoxicity of the tumor by binding with copper. This binding process can remove the copper from the body, stopping angiogenesis as well as activating the mechanisms of cell death, such as apoptosis and necrosis. In PDT, this(More)
Comparative spectroscopic study including the photosensitizers of pyropheophorbide methyl ester (PPME) and pyropheophorbide a (PPa) was performed to study their photodynamic activity. The investigated photosensitizers in a homogeneous system of dimethylformamide (DMF) are not photostable upon irradiation. The photobleaching efficiency of PPa is higher than(More)
and Applied Analysis 3 Proof. Let ξ be fixed. If φ t is in S, then its diffraction Fresnel transform certainly exists. Moreover, differentiating the right-hand side of 2.3 with respect to ξ, under the integral sign, ktimes, yields a sum of polynomials, pk t ξ , say of combinations of t and ξ. That is, ∣ ∣ ∣ ∣ ∣ d dtk Fd ( φ ) ξ ∣ ∣ ∣ ∣ ∣ ∣ ∣ ∣ ∣ ∣ pk t ξ φ(More)
Over the past 20 years we have encountered 13 cases of lower genital tract atresia or obstruction. There were eight cases due to a high transverse vaginal septum. These were dealt with by standard surgical reconstruction. One later recurred and required hysterectomy. Five patients presented with cervical atresia. These were successfully treated by a new(More)
and Applied Analysis 3 Proof. It is clear that K V f and K p V g are continuous and bounded on R+. Moreover, the Fubini’s theorem allows us to interchange the order of integration: ∫ R + f (x) (K V g) (x) dx = ∫ R + (∫ R + f (x) Z p (xy) dx)g (y) dy. (15) Equation (15) follows since the Krätzel kernel Z p (xy) applies for the functions f and g, when the(More)
The Mellin integral transform is an important tool in mathematics and is closely related to Fourier and bilateral Laplace transforms. In this article we aim to investigate the Mellin transform in a class of quaternions which are coordinates for rotations and orientations. We consider a set of quaternions as a set of generalized functions. Then we provide a(More)
Some of the photophysical properties (stationary absorbance and fluorescence, fluorescence decay times and singlet oxygen quantum yields) of chlorins substituted with methoxy groups, hydroxyl groups and hydrocarbonic chains were studied in ethanol and dipalmitoyl-phosphatidylcholine (DPPC) liposomes using steady-state and time-resolved fluorescence(More)
An important issue that should be taken into consideration when applying the molecules in photodynamic therapy (PDT) of cancer is the occurrence of homo-resonance energy transfer process between them. We have determined the probability of energy transfer for sodium zinc (II)-2,9,16,23-phthalocyanine tetracarboxylate (ZnPc(COONa)4) molecules in aqueous NaOH(More)
The tempered ultradistribution space of Roumieu type for the space H μ,ν is defined, which is a subspace of the Hausdörff locally convex topological linear space. Further, results are obtained for the multipliers and operators on the tempered ultradistribution spaces for the distributional Hankel-type transformation spaces.
