Increased sensitivity of glioma cells to 5-fluorocytosine following photo-chemical internalization enhanced nonviral transfection of the cytosine deaminase suicide gene
Despite advances in surgery, chemotherapy and radiotherapy, the outcomes of patients with GBM have not significantly improved. Tumor recurrence in the resection margins occurs in more than 80 % of cases indica...

Open AccessPhotothermal treatment of glioma; an in vitro study of macrophage-mediated delivery of gold nanoshells
One of the major factors that limits the treatment effectiveness for gliomas is the presence of the blood–brain barrier (BBB) which protects infiltrating glioma cells from the effects of anti-cancer agents. Ci...

Targeted delivery of bleomycin to the brain using photo-chemical internalization of Clostridium perfringens epsilon prototoxin
Cells infiltrating into normal brain from malignant brain tumors are protected by the blood brain barrier (BBB) which prevents the delivery and limits the effects of anti-tumor agents. We have evaluated the ab...

Motexafin gadolinium enhances the efficacy of aminolevulinic acid mediated-photodynamic therapy in human glioma spheroids
Photodynamic therapy (PDT) has been investigated as a postoperative treatment in patients with high grade gliomas. The purpose of this in vitro investigation was to determine whether motexafin gadolinium (MGd)...

Evaluation of single versus multiple cryogen spray cooling spurts on in vitro model human skin
Many commercially available dermatologic lasers utilize cryogen spray cooling for epidermal protection. A previous tissue culture study demonstrated that single cryogen spurts (SCS) of 80 ms or less were unlik...

Enhanced cytotoxic effects of 5-aminolevulinic acid-mediated photodynamic therapy by concurrent hyperthermia in glioma spheroids
During photodynamic therapy (PDT) both normal and pathological brain tissue, in close proximity to the light source, can experience significant temperature increases. The purpose of this study was to investiga...

Repetitive 5-aminolevulinic acid-mediated photodynamic therapy on human glioma spheroids
The response of human glioma spheroids to repetitive 5-aminolevulinic acid-mediated photodynamic therapy (PDT) was investigated. In all cases, light fluences were kept below toxic thresholds to simulate condit...

ALA- and ALA-ester-mediated Photodynamic Therapy of Human Glioma Spheroids
The effects of photodynamic therapy (PDT) in human glioma spheroids incubated in 5-aminolevulinic acid (ALA), or ALA esters, are investigated. Spheroid survival and growth are monitored following PDT at repres...
