Cysteine dioxygenase structures from pH 4 to 9: consistent Cys-persulfenate formation at intermediate pH and a Cys-bound enzyme at higher pH

Creator:: Driggers, Camden M., Cooley, Richard B., Sankaran, Banumathi, Hirschberger, Lawrence L., Stipanuk, Martha H., and Karplus, P. Andrew
Abstract:: Mammalian cysteine dioxygenase (CDO) is a mononuclear non-heme iron protein that catalyzes 2 the conversion of cysteine (Cys) to cysteine sulfinic acid (CSA) by an unclarified mechanism. 3 One structural study revealed a Cys-persulfenate (or Cys-persulfenic acid) formed in the active 4 site, but quantum mechanical calculations have been used...

The circadian clock gene period extends healthspan in aging Drosophila melanogaster

Creator:: Krishnan, Natraj, Kretzchmar, Doris, Rakshit, Kuntol, Chow, Eileen, and Giebultowicz, Jadwiga M.
Abstract:: There is increasing evidence that aging is affected by biological (circadian) clocks – the internal mechanisms that coordinate daily changes in gene expression, physiological functions and behavior with external day/night cycles. Recent data suggest that disruption of the mammalian circadian clock results in accelerated aging and increased age‐related pathologies such...

Partial differential equations of Sobolev-Galpern type

Creator:: Showalter, R. E.
Abstract:: A mixed initial and boundary value problem is considered for a partial differential equation of the form Muₜ(x, t)+Lu(x, t)=0, where M and L are elliptic differential operators of orders 2 m and 2l, respectively, with m ≤ l. The existence and uniqueness of a strong solution of this equation...

History of Entomopathogenic Nematology

Creator:: Poinar, George O., Jr. and Grewal, P. S.
Abstract:: The history of entomopathogenic nematology is briefly reviewed. Topic selections include early descriptions of members of Steinernema and Heterorhabditis, how only morphology was originally used to distinguish between the species; descriptions of the symbiotic bacteria and elucidating their role in the nematode- insect complex, including antibiotic properties, phase variants, and...

Exploring Phytoplankton Population Growth to Enhance Quantitative Literacy: Putting Vision & Change into Action

Creator:: Baumgartner, Erin, Biga, Lindsay, Bledsoe, Karen, Dawson, James, Grammer, Julie, Howard, Ava, and Snyder, Jeffrey
Abstract:: Quantitative literacy is essential to biological literacy (and is one of the core concepts in Vision and Change in Undergraduate Biology Education: A Call to Action; AAAS 2009). Building quantitative literacy is a challenging endeavor for biology instructors. Integrating mathematical skills into biological investigations can help build quantitative literacy. In...

Sampling, feasibility, and priors in Bayesian estimation

Creator:: Chorin, Alexandre J., Lu, Fei, Miller, Robert N., Morzfeld, Matthias, and Tu, Xuemin
Abstract:: Importance sampling algorithms are discussed in detail, with an emphasis on implicit sampling, and applied to data assimilation via particle filters. Implicit sampling makes it possible to use the data to find high-probability samples at relatively low cost, making the assimilation more efficient. A new analysis of the feasibility of...

A class of Markov chains with no spectral gap

Creator:: Kovchegov, Yevgeniy and Michalowski, Nicholas
Abstract:: In this paper we extend the results of the research started by the first author in which Karlin-McGregor diagonalization of certain reversible Markov chains over countably infinite general state spaces by orthogonal polynomials was used to estimate the rate of convergence to a stationary distribution. We use a method of...
