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 ... -
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 ... -
Axial Shear Modulus of A Fiber-Reinforced Composite with Random Fiber Cross-Sections
(1981-04-14)A study is made of the effective axial shear modulus of a fiber reinforced material with random fiber cross-sections so that the micromechanics is governed by stochastic differential equations. A coarse-graining procedure ... -
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 ... -
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. ... -
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 ... -
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, ... -
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 ... -
Cloning and Characterization of Ancylostoma-secreted Protein
(1996-03-22)The developmentally arrested third stage infective larva of hookworms resumes development upon entry into the definitive host. This transition to parasitism can be modeled in vitro by stimulating infective larvae with a ... -
Behavioral, ecological, and molecular genetic analyses of reproductive strategies in the Amazonian dart-poison frog, Dendrobates ventrimaculatus
(1997)We report the first field and genetic studies of the reproductive strategies of the Amazonian dart-poison frog Dendrobata vtntrimaculatus, a species with biparental care. Neither males nor females are strictly monogamous. ... -
Characterization of a Low Affinity Thyroid Hormone Receptor Binding Site within the Rat GLUT4 Gene Promoter
(1997-03)Previous studies have demonstrated that thyroid hormone (T3) stimulates insulin-responsive glucose transporter (GLUT4) transcription and protein expression in rat skeletal muscle. The aim of the present study was to define ... -
Clinical use of rifampicin during routine reporting of rifampicin susceptibilities: a lesson in selective reporting of antimicrobial susceptibility data
(1997-10)Increased use of rifampicin for in-patients was noted after the laboratory began reporting rifampicin susceptibilities routinely for all Gram-positive bacterial isolates. The appropriateness of rifampicin use was evaluated ... -
Cerebral Ischemia/Reperfusion Increases Endothelial Nitric Oxide Synthase Levels by An Indomethacin-Sensitive Mechanism
(1998-01-01)In anesthetized piglets, endothelial and neuronal nitric oxide synthase (eNOS and nNOS, respectively) levels were investigated after global cerebral ischemia. Increased intracranial pressure was used to produce 5 or 10 ... -
Characterization of proteins binding the 3′ regulatory region of the IL-3 gene in IL-3-dependent and autocrine-transformed hematopoietic cells
(1998-03-08)Previously we documented the prolongation of the IL-3 mRNA half-life in an autocrine-transformed cell line. This cell line has an intracisternal type A particle transposition in the IL-3 mRNA 3′ untranslated region which ... -
Characterizations of Cross-Bridges in the Presence of Saturating Concentrations of MgAMP-PNP in Rabbit Permeabilized Psoas Muscle
(1998-06)Several earlier studies have led to different conclusions about the complex of myosin with MgAMP-PNP. It has been suggested that subfragment 1 of myosin (S1)-MgAMP-PNP forms an S1-MgADP-like state, an intermediate between ... -
Cerebrovascular Reactivity Remains Intact after Cortical Depolarization in Newborn Piglets
(1999-01-01)Cerebrovascular reactivity is severely affected by ischemia, and changes in vascular responses have been reported after cortical spreading depression and head trauma as well. Cortical depolarization (CD) occurs during ... -
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 ... -
Last Glacial Maximum in an Andean cloud forest environment (Eastern Cordillera, Bolivia): Comment and Reply
(2003-01)Whether the climate of tropical South America during the Last Glacial Maximum (LGM) was colder and drier or colder and wetter than present day has been widely debated. It is accepted, however, that the LGM in tropical South ... -
Low alpha power (7.5–9.5 Hz) changes during positive and negative affective learning
(2003-03)There is evidence that the positive and the negative word lists of the Affective Auditory Verbal Learning Test (AAVL) are useful with regard to mood induction. To date, however, changes in brain activation, as indicated ...
