Interactions between microtubules (MTs) and filamentous actin (f-actin) are involved in directed cell locomotion, but are poorly understood. To test the hypothesis that MTs and f-actin associate with one another and affect each other's organization and dynamics, we performed time-lapse dual-wavelength spinning-disk confocal fluorescent speckle microscopy(More)
OBJECTIVE There is growing interest in using PET/CT for evaluating early response to therapy in cancer treatment. Although widely available and convenient to use, standardized uptake value (SUV) measurements can be influenced by a variety of biologic and technologic factors. Many of these factors can be addressed with close attention to detail and(More)
Fluorescent speckle microscopy (FSM) uses a small fraction of fluorescently labeled subunits to give macromolecular assemblies such as the cytoskeleton fluorescence image properties that allow quantitative analysis of movement and subunit turnover. We describe a multispectral microscope system to analyze the dynamics of multiple cellular structures labeled(More)
Fluorescent speckle microscopy (FSM) uses low levels of fluorescent proteins to create fluorescent speckles on cytoskeletal polymers in high-resolution fluorescence images of living cells. The dynamics of speckles over time encode subunit turnover and motion of the cytoskeletal polymers. We sought to improve on current FSM technology by first expanding it(More)
Thromboxane A(2) (TXA(2)) is an arachidonic acid metabolite that is released during tissue trauma and elicits platelet aggregation and vascular smooth muscle contraction. Previous research has shown that TXA(2) stimulates pulmonary and cardiac vagal afferent neurons. Therefore, we hypothesized that the presence of the TXA(2) receptor (TP) in vagal neurons(More)
We measured actin turnover in lamellipodia and lamellae of migrating cells, using quantitative Fluorescent Speckle Microscopy. Lamellae disassembled at low rates from the front to the back. However, the dominant feature in their turnover was a spatially random pattern of periodic polymerization and depolymerization moving with the retrograde flow. Power(More)
PURPOSE Utilization of sequencing to screen the general population for preventable monogenic conditions is receiving substantial attention because of its potential to decrease morbidity and mortality. However, the selection of which variants to return is a serious implementation challenge. Procedures must be investigated to ensure optimal test(More)
Increasing the temperature of microfiltration (MF) to >50°C may allow for operation at higher fluxes and reduce the bacterial growth during MF. However, there is a concern that operating at higher temperatures could cause calcium phosphate precipitation that would lead to membrane fouling. Our objective was to determine the effect of operating a 0.1-µm(More)
There are a number of new genetic tests and a variety of recommendations for obstetrician-gynecologists. In recent years, screening of low-risk pregnant women with noninvasive prenatal testing has been proposed as well as universal BRCA1 and BRCA2 screening of all women regardless of risk status. Both proposed genetic screening tests raise complicated(More)
Thirteen diethanolamine compounds were tested for their biodegradability employing (1) a bacterium selectively isolated from an industral cutting fluid, and (2) an acclimatized sewage population obtained from a domestic waste treatment plant. Pure culture growth and biochemical oxygen demand studies with the isolate showed that only diethanolamine,(More)
