From our everyday experiences, we know that as light travels through a medium it attenuates due to absorption and scattering. Absorption is the cause of color in tea or grape juice, and it is described by Beer's law. Scattering is the reason why...
Process control -- Statistical methods. Process control -- Mathematical models. Markov processes.
Many applications of current interests involve detecting instances of processes from databases or streams of sensor reports. Detecting processes relies on identifying evidences for the existence of such processes from usually noisy and incomplete...
This project examined the regulation of hepatocyte growth factor (HGF) and stromal-derived factor 1 (SDF-1) secretion by primary cultures of human stromal fibroblasts of the uterus, cervix, and ectocervix. HGF is secreted constitutively in...
We consider join congruence relations on geometric lattices from three different points of view. First, recognizing that every matroid has an associated geometric lattice, we consider matroid operations and give conditions for when it is possible...

Chronic neuropathic pain is a debilitating condition that exacts an emotional and physical toll on its sufferers and their family as well as an enormous monetary toll on society. Neuropathic pain can arise following nerve injury induced by trauma,...
Advances in medicine such as organ transplantations and cancer therapies involve the use of immunosuppressant drugs have led to rises in at risk patients and invasive fungal infections (IFIs). The filamentous fungus Aspergillus fumigatus is the...
Magnetic resonance imaging. ; Nuclear magnetic resonance.
Diffusion-weighted magnetic resonance imaging (MRI) provides unique contrast reflecting the translational motion of water in its microscopic environment. This imaging modality has been shown to highlight infarcted regions within minutes after an...
Studies have implicated the essential role of Vitamin A (VA) and its active metobolite, retinoic acid (RA) in both host defense and tolerance through manipulation of various immune cells, including T cells, B cells, macrophages and others. CD8⁺ T...
Traditionally, mast cells have been studied for their role as proinflammatory effector cells in allergic disorders. Recent findings however have opened up the discussion in the community of immunologists regarding MCs should be considered as...
The motivational and rewarding properties of our immediate environment affect how humans interact with our world in a number of ways. One important aspect in which reward representation shapes behavior is in the development, maintenance and...
Indole alkaloids -- Synthesis. Ring formation (Chemistry). Radicals (Chemistry).
A novel radical cyclization of 2-bromoindoles was examined, generating a series of hexahydropyrrolo[3,4- b ]indoles in fair yield. This process involved the generation of a variety of indole-3-carboxamides followed by the introduction of bromine at...
This research attempts to combine known methodology with new chemistry towards the preparation of extended polycyclic aromatic hydrocarbons (PAH). The generation and Diels-Alder trapping of 1,7- and 2,6-naphthalene bisarynes was attempted for the...
NAD (Coenzyme) -- Metabolism. Nicotinamide -- Mechanism of action. Genetic regulation. Nicotinamide-beta-riboside.
NAD+ is an essential co-enzyme for hydride transfer enzymes and a consumed substrate of multiple signaling enzymes including the sirtuins, a family of protein lysine deacetylases shown to regulate longevity in a wide array of organisms. We have...
In nematodes an alternative third larval stage, often called the dauer stage, allows the animals to weather periods of low food availability (if free living) or to disperse (if parasitic). Recently, studies of mutations in the nematode...

A novel synthetic route to the synthesis of 9-propyl-10-azacyclododecan-12-olide (1), a natural allomone isolated from the Mexican bean beetle pupa, is presented. The salient features of this synthetic route are a regioselective Beckmann...

Near-infrared (NIR) light has the potential to be used as a non-invasive means of diagnostic imaging within the human breast. Due to the diffusive nature of light in tissue, computational model-based methods are required for functional imaging...
