Single pancreatic endocrine cells (PEC) have been demonstrated to restore normoglycemia when transplanted intracerebrally in diabetic rat recipients across a major histocompatibility barrier without immunosuppression. Twelve out of twelve transplants of purified PEC have achieved long-term survival of over 176 days. This approach would provide a model to identify the specific cell(s) as inducer...

Conventional eddy current using single-frequency excitation has limited material characterization capabilities. Enrichment of the spectral information of the signal with techniques such as multifrequency or swept frequency inspection could be employed to improve the inspection process. Broadband excitation is also implemented with time-domain inspection using pulsed eddy current PEC. The spectr...

Inhalation delivery of aerosolized antibacterials is preferred over conventional methods of delivery for targeting lung infection. The present study is concerned with the development and characterization of a novel, spray dried, aerosolized, chitosan polyelectrolyte complex (PEC) based microparticles containing antibacterials for the treatment of lung infections. Chitosan polyelectrolyte comple...

Introduction: The current work was aimed to design and synthesize novel crosslinked pH-sensitive gelatin/pectin (Ge/Pec) hydrogels using different polymeric ratios and to explore the effect of polymers and degree of crosslinking on dynamic, equilibrium swelling and in vitro release behavior of the model drug (Mannitol). Methods: The Ge/Pec based hydrogels were prepared using glutaraldehyde as t...

PURPOSE Prostate cancer is detected with increasing frequency but has a highly variable natural history and prognosis and active surveillance of men with low-risk prostate cancer would benefit greatly from minimally invasive methods to identify progression. We describe here two novel in vivo metrics of cell proliferation in men with prostate neoplasia. EXPERIMENTAL DESIGN Three groups of men ...

TiO₂ nanostructures-based photoelectrochemical (PEC) cells are under worldwide attentions as the method to generate clean energy. For these devices, narrow-bandgap semiconductor photosensitizers such as CdS and CdSe are commonly used to couple with TiO₂ in order to harvest the visible sunlight and to enhance the conversion efficiency. Conventional methods for depositing the photosensitizers on ...

A green photoelectrochemical (PEC) process with simultaneous SO2 removal and H2 production has attracted an increasing attention. The proposed process uses flue gas SO2 to improve H2 production. The improvement of the efficiency of this process is necessary before it can become industrial viable. Herein, we reported a Mo modified BiVO4 photocatalysts for a simultaneous SO2 removal and H2 produc...
