Cloning of a catabolite repression control (crc) gene from Pseudomonas aeruginosa, expression of the gene in Escherichia coli, and identification of the gene product in Pseudomonas aeruginosa.
(1991-11)Mutants which are defective in catabolite repression control (CRC) of multiple independently regulated catabolic pathways have been previously described. The mutations were mapped at 11 min on the Pseudomonas aeruginosa ... -
Cloning of somatolactin alpha and beta cDNAs in zebrafish and phylogenetic analysis of two distinct somatolactin subtypes in fish
(2004-09-01)Somatolactin (SL) is a pituitary hormone belonging to the growth hormone/prolactin superfamily, with recognizable homologues in all fish taxa examined to date. Although sequences from most fish share reasonably high sequence ... -
Closed form bound-state perturbation theory
(1980)The perturbed Schrödinger eigenvalue problem for bound states is cast into integral form using Green's Functions. A systematic algorithm is developed and applied to the resulting equation giving rise to approximate solutions ... -
A Clostridium difficile-Specific, Gel-Forming Protein Required for Optimal Spore Germination
(2017-01-17)Clostridium difficile is a Gram-positive spore-forming obligate anaerobe that is a leading cause of antibiotic-associated diarrhea worldwide. In order for C. difficile to initiate infection, its aerotolerant spore form ... -
Co-occurrence of ecologically similar species of Hawaiian spiders reveals critical early phase of adaptive radiation
(2018-06-19)Background: The processes through which populations originate and diversify ecologically in the initial stages of adaptive radiation are little understood because we lack information on critical steps of early divergence. ... -
Coagulation Factor XIIIa Undergoes a Conformational Change Evoked by Glutamine Substrate
(1988-06-05)Coagulation factor XIIIa, plasma transglutaminase(endo-g-glutamine:e-lysine transferase EC 2.3.2.13) cata-lyzes isopeptide bond formation between glutamine andlysine residues and rapidly cross-links fibrin clots. ... -
Coastal barrier stratigraphy for Holocene high-resolution sea-level reconstruction
(2016-12-08)The uncertainties surrounding present and future sea-level rise have revived the debate around sea-level changes through the deglaciation and mid- to late Holocene, from which arises a need for high-quality reconstructions ... -
Cohomology classes associated to anomalies
(1993-12)One of the proposed settings for the description of anomalies in the setting of gauge field theories is a local bicomplex associated to a principal fiber bundle $ G \to P \to M$. It is a bigraded algebra with two differentials ... -
Combination of Raman tweezers and quantitative differential interference contrast microscopy for measurement of dynamics and heterogeneity during the germination of individual bacterial spores
(2010-09-01)Raman tweezers and quantitative differential interference contrast (DIC) microscopy are combined to monitor the dynamic germination of individual bacterial spores of Bacillus species, as well as the heterogeneity in this ... -
Combined effect of free and forced convection on MHD flow in a rotating porous channel
(1982)This paper gives a steady linear theory of the combined effect of the free and forced convection in rotating hydromagnetic viscous fluid flows in a porous channel under the action of a uniform magnetic field. The flow is ... -
Combined effects of aberrant MEK1 activity and BCL2 overexpression on relieving the cytokine dependency of human and murine hematopoietic cells
(2000-06-06)The MEK1 oncoprotein plays a critical role in Ras/Raf/ MEK/MAPK-mediated transmission of mitogenic signals from cell surface receptors to the nucleus. In order to examine this pathway's role in leukemic transformation, a ... -
Combining ultrasonography and noncontrast helical computerized tomography to evaluate Holmium laser lithotripsy
(2016-11-14)The purpose of the study was to establish a mathematical model for correlating the combination of ultrasonography and noncontrast helical computerized tomography (NCHCT) with the total energy of Holmium laser lithotripsy. In ... -
Commentary: Effect of Skeletal Muscle Native Tropomyosin on the Interaction of Amoeba Actin with Heavy Meromyosin
(2016-08-31)Keywords: troponin, tropomyosin, cardiomyopathy, troponin T, mutations Troponin-tropomyosin inhibits skeletal and cardiac muscle contraction at low Ca rigor-type myosin S1 to actin-tropomyosin-troponin, particularly at ... -
Compact NMR relaxometry of human blood and blood components
(2016-10)Nuclear magnetic resonance relaxometry is a uniquely practical and versatile implementation of NMR technology. Because it does not depend on chemical shift resolution, it can be performed using low- field compact instruments ... -
Compact operators and nest representations of limit algebras
(2007-01-04)In this paper we study the nest representations $ \rho: \mathcal{A} \longrightarrow \operatorname{Alg} \mathcal{N}$ of a strongly maximal TAF algebra $ \mathcal{A}$, whose ranges contain non-zero compact operators. We ... -
Compactifications of convergens spaces
(1979)This paper summarizes most of the results to date on convergence space compactifications, and establishes necessary and sufficient conditions for the existence of largest and smallest compactifications subject to various ... -
Comparative DNA Analysis of Solid Tumors by Flow Cytometric and Image Analyses of Touch Imprints and Flow Cell Suspensions
(1992-09-01)Comparative DNA analysis by flow cytometric (FCM) and image analyses (IA) has shown a high concordance rate. When present, discordance has been attributed to the presence of aneuploid cell populations detected only by IA, ... -
Comparative evaluation of two severe acute respiratory syndrome (SARS) vaccine candidates in mice challenged with SARS coronavirus
(2006-03-01)Two different severe acute respiratory syndrome (SARS) vaccine strategies were evaluated for theirability to protect against live SARS coronavirus (CoV) challenge in a murine model of infection.A whole killed (inactivated ... -
