Hyperglycemia and the onset of insulin resistance or deficiency, both, are hallmarks group diseases known as diabetes. Ultimately, subcutaneous injection is most effective treatment for diabetic patients. However, patients must self-administer at least twice daily rest their lives, this form administration frequently uncomfortable inconvenient. Infections, precipitation, lipoatrophy, lipohypert...
The pathogenesis of many neurodegenerative diseases, including Alzheimer’s disease (AD) is characterized by protein aggregation into amyloid fibrils. In AD, the fibrils are of the amyloid-β (Aβ) peptide. The development of new approaches based on nanotechnology for early detection and potential treatment of AD is of high current interest. This review describes a pioneering approach involving th...
The feasibility of preparing microparticles with high insulin loading suitable for needle-free ballistic drug delivery by spray-freeze-drying (SFD) was examined in this study. The aim was to manufacture dense, robust particles with a diameter of around 50 microm, a narrow size distribution and a high content of insulin. Atomization using ultrasound atomizers showed improved handling of small li...
Silybin, is one imminent therapeutic for drug induced hepatotoxicity, human prostate adenocarcinoma and other degenerative organ diseases. Recent evidences suggest that silybin influences gluconeogenesis pathways favorably and is beneficial in the treatment of type 1 and type 2 diabetes. The compound however is constrained due to solubility (0.4 mg/mL) and bioavailabilty limitations. Appropriat...
In-line holographic microscopy images of micrometer-scale fractal aggregates can be interpreted with an effective-sphere model to obtain each aggregate's size and the population-averaged fractal dimension. We demonstrate this technique experimentally using model fractal clusters of polystyrene nanoparticles and fractal protein aggregates composed of bovine serum albumin and bovine pancreas insu...
Boronic acids, known to bind diols, were screened to identify non-inflammatory cross-linkers for the preparation of glucose sensitive and insulin releasing agglomerates of liposomes (Agglomerated Vesicle Technology-AVT). This was done in order to select a suitable replacement for the previously used cross-linker, ConcanavalinA (ConA), a lectin known to have both toxic and inflammatory effects i...
Increasing cell survival in stem cell therapy is an important challenge for the field of regenerative medicine. Here, we report theranostic mesoporous silica nanoparticles that can increase cell survival through both diagnostic and therapeutic approaches. First, the nanoparticle offers ultrasound and MRI signal to guide implantation into the peri-infarct zone and away from the most necrotic tis...
