Sugar-pendant [60] fullerene derivatives have been prepared from carbohydrate-linked azides 1a-e. Both monosugar (4a-e) and bissugar derivatives (5a-e) produce singlet oxygen ((1)O(2)) under laser irradiation (355 nm) proved by the direct observation

Publikováno v: Cancer Letters. 199:45-51

We investigated the effect of multiple stress waves with peak stress of less than 3 MPa on chemosensitivity of HeLa cells adhered on plastic. HeLa cells exposed to stress waves retained more than 95% of the viability found in untreated cells. The sca

Publikováno v: Journal of Biochemistry. 134:219-224

In this report, we describe a laser-latex combination system that enables membrane-impermeable molecules to penetrate cell membranes. Laser light (Q-switched Nd:YAG laser, 532.5 nm) was used to irradiate a mixture of commercial latex particles (blue

Comparison of phototoxicity mechanism between pulsed and continuous wave irradiation in photodynamic therapy

Autor: Yukihiro Umebayashi, Tsuyoshi Nishisaka, Yuuichi Miyamoto

Publikováno v: Journal of Photochemistry and Photobiology B: Biology. 53:53-59

A study has been conducted in which HeLa cells are incubated with hematoporphyrin derivative (HpD) for 1 h (1 microgram/ml of HpD in PBS) to compare the use of continuous wave (CW) and pulsed laser (10 Hz repetition rate and 7-9 ns pulse width) light
