There is an urgent need for the discovery and development of new antitubercular agents that target new biochemical pathways and treat drug resistant forms of the disease. One approach to addressing this need is through high-throughput screening of medicinally relevant libraries against the whole bacterium in order to discover a variety of new, active(More)
Plant-made vaccines have been the subject of intense interest because they can be produced economically in large scale without the use of animal-derived components. Plant-made therapeutic vaccines against challenging chronic diseases, such as cancer, have received little research attention, and no previous human clinical trials have been conducted in this(More)
(+)-Calanolide A (NSC 650886) has previously been reported to be a unique and specific nonnucleoside inhibitor of the reverse transcriptase (RT) of human immunodeficiency virus (HIV) type 1 (HIV-1) (M. J. Currens et al., J. Pharmacol. Exp. Ther., 279:645-651, 1996). Two isomers of calanolide A, (-)-calanolide B (NSC 661122; costatolide) and(More)
In this paper, we describe DyRecT (Dynamic Reconfigu-ration Toolkit) a software library that allows programmers to develop adaptively parallel message-passing MPI programs for clusters of workstations. DyRecT provides a high-level API that can be used for writing adaptive parallel HPF-like programs while hiding most of the details of the dynamic(More)
A concurrent software application, whether running on a single machine or distributed across multiple machines, is composed of tasks that interact (communicate and sychronize) in order to achieve some goal. Developing such concurrent programs so they cooperate effectively is a complex task, requiring that progrmmers craft their modules–the components(More)
RATIONALE Premature termination codons (PTCs) in the cystic fibrosis transmembrane conductance regulator (CFTR) gene cause cystic fibrosis (CF). Several agents are known to suppress PTCs but are poorly efficacious or toxic. OBJECTIVES To determine whether there are clinically available agents that elicit translational readthrough and improve CFTR function(More)
Alzheimer disease (AD) is the most common neurodegenerative disease, and with Americans' increasing longevity, it is becoming an epidemic. There are currently no effective treatments for this disorder. Abnormalities of Tau track more closely with cognitive decline than the most studied therapeutic target in AD, amyloid-β, but the optimal strategy for(More)
2-Chloro-9-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)-adenine (Cl-F-ara-A) has activity against the P388 tumor in mice on several different schedules. Biochemical studies with a chronic myelogenous leukemia cell line (K562) grown in cell culture have been done in order to better understand its mechanism of action. Cl-F-ara-A was a potent inhibitor of K562(More)
Kinase targets are being pursued in a variety of diseases beyond cancer, including immune and metabolic as well as viral, parasitic, fungal and bacterial. In particular, there is a relatively recent interest in kinase and ATP-binding targets in Mycobacterium tuberculosis in order to identify inhibitors and potential drugs for essential proteins that are not(More)
Tuberculosis treatments need to be shorter and overcome drug resistance. Our previous large scale phenotypic high-throughput screening against Mycobacterium tuberculosis (Mtb) has identified 737 active compounds and thousands that are inactive. We have used this data for building computational models as an approach to minimize the number of compounds(More)
