Magneto-optic (MO) imaging produces images of magnetic flux leakage from surface and sub-surface defects. The presence of domain boundaries in the MO sensor produces a characteristic artefact in the images that renders detection of cracks difficult. This paper presents two different approaches for the removal of domain boundaries in MO images. The first(More)
TP-38 is a recombinant chimeric targeted toxin composed of the EGFR binding ligand TGF-alpha and a genetically engineered form of the Pseudomonas exotoxin, PE-38. After in vitro and in vivo animal studies that showed specific activity and defined the maximum tolerated dose (MTD), we investigated this agent in a Phase I trial. The primary objective of this(More)
The goal of this investigation was to measure changes in vascular permeability, pore cutoff size, and number of transvascular transport pathways as a function of time and in response to vascular endothelial growth factor (VEGF), placenta growth factor (PlGF-1 and PlGF-2), or basic fibroblast growth factor (bFGF). Two human and two murine tumors were(More)
Molecular charge is one of the main determinants of transvascular transport. There are, however, no data available on the effect of molecular charge on microvascular permeability of macromolecules in solid tumours. To this end, we measured tumour microvascular permeability to different proteins having similar size but different charge. Measurements were(More)
Electric field mediated gene delivery or electrotransfection is a widely used method in various studies ranging from basic cell biology research to clinical gene therapy. Yet, mechanisms of electrotransfection are still controversial. To this end, we investigated the dependence of electrotransfection efficiency (eTE) on binding of plasmid DNA (pDNA) to(More)
Pulsed electric fields can enhance interstitial transport of plasmid DNA (pDNA) in solid tumors. However, the extent of enhancement is still limited. To this end, the effects of cellular resistance to electric field-mediated gene delivery were investigated. The investigation used two tumor cell lines (4T1 (a murine mammary carcinoma) and B16.F10 (a(More)
BACKGROUND To investigate the association between estimated trans-lamina cribrosa pressure difference (TLCPD) and prevalence of normal tension glaucoma (NTG) with low-teen and high-teen intraocular pressure (IOP) using a population-based study design. METHODS A total of 12,743 adults (≥ 40 years of age) who participated in the Korean National Health and(More)
Plasmids may have unique advantages as a gene delivery system. However, a major obstacle is the low in vivo transduction efficiency. In this study, an electroporation-based gene transduction approach was taken to study the effect of interleukin (IL)-2 or IL-12 gene transduction on the growth of experimental murine tumors. Significant intratumoral gene(More)
[17] The diameters of a large number of spheres (typically ~ 200 spheres) were obtained from scanned TEM images processed using ImageJ and tabulated. The size distribution, defined as the standard deviation divided by the mean sphere diameter, was subsequently evaluated as such for all samples reported. The shell thickness cannot be obtained by simply(More)
Lowering intraocular pressure (IOP) delays or prevents the loss of vision in primary open-angle glaucoma (POAG) patients with high IOP and in those with normal tension glaucoma showing progression. Abundant evidence demonstrates that inhibition of contractile machinery of the trabecular meshwork cells is an effective method to lower IOP. However, the(More)
