Let X denote the solution process of the stochastic equation dX{t) = a(X(t)) dt + a(X(t)) d\V{t). In this paper, conditions on a(and nd cr(are re given under which the sample paths of X are differentiable at t = 0 with probability one. Variations of these results are obtained leading to a new uniqueness criterion for solutions of stochastic equations. If(More)
A full description of the ontogeny of the beta cell would guide efforts to generate beta cells from embryonic stem cells (ESCs). The first step requires an understanding of definitive endoderm: the genes and signals responsible for its specification, proliferation, and patterning. This report describes a global marker of definitive endoderm, Claudin-6(More)
The clinical relevance of the small airways in persistent asthma has been gaining greater recognition in recent years [1]. Studies have shown that a significant proportion of asthmatics on standard treatment fail to achieve satisfactory asthma control. For example, in one study of 3421 asthmatic subjects who underwent guideline-driven dose titration with(More)
Scientists constantly make groundbreaking discoveries, some of which receive attention from the press. We designed a course intended for a lay audience that provides the scientific background to appreciate these reports more fully. We discuss three topics in the life sciences: stem cells, cancer, and infectious disease. The course is structured to blend(More)
PURPOSE We evaluated whether Gly16Arg beta2-receptor genotype relates to impulse oscillometry (IOS) in a real-life clinic setting. METHODS Patients with persistent asthma taking inhaled corticosteroid ± long-acting beta-agonist (ICS ± LABA) were evaluated. We compared genotype groups comprising either no Arg copies (i.e. GlyGly) versus one or two Arg(More)
Professional Associates has been certified by the Texas Department of Insurance (TDI) as an independent review organization (IRO) (#IRO5288). Texas Insurance Code Article 21.58C, effective September 1, 1997, allows a patient, in the event of a life-threatening condition or after having completed the utilization review agent's internal process, to appeal an(More)
