Photochemical internalization as an adjunct to marginal surgery in a human sarcoma model
Norum, Ole-Jacob,Giercksky, Karl-Erik,Berg, Kristian Korean Society of Photoscience 2009 Photochemical & photobiological sciences Vol.8 No.6
Local recurrences after inadequate surgery are a major challenge in many cancers. Photochemical internalization (PCI) is a new technology to release endocytosed macromolecules into the cytosol by a photochemical rupture of the endocytic vesicles. A recent study on an invasive human fibrosarcoma xenograft HT1080 indicated low sensitivity of the tumour periphery to disulfonated aluminium phthalocyanine ($AlPcS_{2a}$)-based photochemical treatment. The main goal of the present study was to evaluate the sensitivity of the remaining tumour after marginal resection of the HT1080 tumour to the photochemical treatment alone and PCI of bleomycin. $AlPcS_{2a}$ and bleomycin was systemically administrated 48 h and 30 min, respectively, prior to surgery and immediately followed by intra-operative light exposure at 670 nm ($15\;J\;cm^{-2}$). PCI of bleomycin as an adjunct to surgery did significantly delay tumour growth in contrast to the photochemical treatment alone. The results indicate that PCI of bleomycin may be an efficient intra-operative technique to eradicate cancer cells in the wound bed after inadequate surgery.

This paper presents a tubular reciprocating translational motion permanent magnet synchronous motor for percussive drilling applications for offshore oil & gas industry. The motor model and rock model are built up by doing force analysis of the motor and analyzing the physical procesof impact. The optimization of input voltage waveforms to maximize the rate of penetration is done by simulations. The simulation results show that the motor can be utilized in percussive drilling applications and achieve a very large impact force. Simulation results for optimization also show that second harmonic input voltage produces a higher rate of penetration than the sine wave and fourth harmonic input voltages.
