Optically-pumped atomic magnetometers (OPMs) have seen great advancements over the past years and emerge as a promising alternative to the superconducting quantum interference device (SQUID) detector system that is currently used in magnetoencephalography (MEG). OPMs are more affordable to manufacture, and its sensitivity at room temperature is comparable to that of the SQUID detectors....
Our lab has been investigating the use of laser-induced breakdown spectroscopy (LIBS) for the
rapid identification of bacteria in clinical specimens. The ability to rapidly identify harmful
pathogens in such specimens is crucial for initiating appropriate treatment of infectious diseases
that can kill within hours of the onset of symptoms. Current laboratory techniques can take as
long as...
We propose a method--multi-seeded MD (molecular dynamics) simulation--to effectively sample the conformational space of short peptides. Multi-seeded simulations prepare an exhaustive set of distinct initial conformations by assigning uniformly-distributed phi/psi angles for each amino acid. These distinct conformations act as seeds for subsequent short relaxation simulations. We apply this...
Slag from nickel smelting operations in the Sudbury basin in Ontario has become ubiquitous. This material rich in heavy metals such as iron, upon ingestion has the potential to effect physical, radiological, chemical, mechanical, and structural changes in biological systems. In this work, we analyze the effects of slag ingestion through diet, on several quantitative and qualitative parameters...
In principle, lasers allow surgery at the single cell limit. But in practice, shock waves and thermal damage still pose problems. We have employed a picosecond infrared laser lasing at the water absorption peak at 3um to excite water molecules under desorption by impulsive vibrational excitation, leading to ablation processes faster than thermal and acoustic energy transfers. This rapid...
Background: In Alzheimer’s disease (AD), amyloid deposits have been reported primarily in the far peripheral retina. In polarimetry images, we examine signal strength, location of retinal deposits and predictions from these deposits of AD associated disease changes in the brain.
Methods: The severity of AD associated brain pathology was assessed (NIA guidelines) and retinas from donors...
