A Long Helix from the Central Region of Smooth Muscle Caldesmon
(East Carolina University, 1991-07-25)The central region of smooth muscle caldesmon is predicted to form α-helices on the basis of its primary structure. We have isolated a fragment (CT54) that contains this region. The hydrodynamic properties and the electron ... -
The Interaction of Caldesmon with the COOH Terminus of Actin
(East Carolina University, 1991-10-25)Caldesmon interacts with the NH2-terminal region of actin. It is now shown in airfuge centrifugation experiments that modification of the penultimate cysteine residue of actin significantly weakens its binding to caldesmon ... -
Nucleotide sequence of the phosphoprotein (P) gene of Newcastle disease virus (strain Beaudette C).

Restoration of insulin responsiveness in skeletal muscle of morbidly obese patients after weight loss. Effect on muscle glucose transport and glucose transporter GLUT4.
(East Carolina University, 1992-02)A major defect contributing to impaired insulin action in human obesity is reduced glucose transport activity in skeletal muscle. This study was designed to determine whether the improvement in whole body glucose disposal ... -
Analysis of rRNA restriction fragment length polymorphisms from Bacteroides spp. and Bacteroides fragilis isolates associated with diarrhea in humans and animals.
(East Carolina University, 1992-04)The Escherichia coli rRNA operon rrnB was used as a 32P-labeled hybridization probe in Southern blots of genomic DNAs from representative strains of the saccharolytic, gram-negative, obligate anaerobes of the genus Bacteroides. ... -
Is type II diabetes mellitus (NIDDM) a surgical disease?
(East Carolina University, 1992-06)Since February 1, 1980, 515 morbidly obese patients have undergone the Greenville gastric bypass (GGB) operation. Of these, 212 (41.2%) were euglycemic, 288 (55.9%) were either diabetic or had glucose intolerance, and ... -
Localization and Characterization of a 7.3-kDa Region of Caldesmon Which Reversibly Inhibits Actomyosin ATPase Activity
(East Carolina University, 1992-08-15)Cleavage of caldesmon with chymotrypsin yields a series of fragments which bind both calmodulin and actin and inhibit the binding of myosin subfragments to actin and the subsequent stimulation of ATPase activity. Several ... -
Civilian field surgery in the rural trauma setting: a proposal for providing optimal care.
(East Carolina University, 1992-09)Rural trauma presents unique problems for surgical care. While military surgeons are prepared to provide care at or near the scene of battle, civilian literature is devoid of reports for care provided by surgeons at sites ... -
Deoxyguanosine-resistant Leukemia L1210 Cells: Loss of Specific Deoxyribonecleoside Kinase Activity
(East Carolina University, 1993-01-05)A mouse leukemia L1210 cell line was selected for resistance to deoxyguanosine. The deoxyguanosine-resistant cells (dGuo-R) were 126-fold less sensitive to deoxyguanosine than the wild-type cells. The IC50 values for araC ... -
Contractile activity restores insulin responsiveness in skeletal muscle of obese Zucker rats.
(East Carolina University, 1993-01-15)Both insulin and contraction stimulate glucose transport in skeletal muscle. Insulin-stimulated glucose transport is decreased in obese humans and rats. The aims of this study were (1) to determine if contraction-stimulated ... -
Isolation and characterization of Bordetella bronchiseptica mutants deficient in siderophore activity.
(East Carolina University, 1993-02)Iron acquisition by the gram-negative pathogens Bordetella bronchiseptica and Bordetella pertussis is thought to occur by hydroxamate siderophore-mediated transport as well as an apparently siderophore-independent process ... -
Method for nerve growth induction
(1993-03-16)A composition comprising nerve growth factor and 2-amino-1,1,3-tricyano-1-propene useful for the induction, stimulation, and maintenance of nerve growth, and methods of potentiating choline O-acetyltransferase and tyrosine ... -

(1993-03-16)A composition comprising nerve growth factor and 2-amino-1,1,3-tricyano-1-propene useful for the induction, stimulation, and maintenance of nerve growth, and methods of potentiating choline O-acetyltransferase and tyrosine ... -
Epigenetic mechanisms of drug resistance: drug-induced DNA hypermethylation and drug resistance.
(East Carolina University, 1993-04-01)In a model system employing Chinese hamster V-79 cells, the DNA synthesis inhibitor 3'-azido-3'- deoxythymidine (BW A509U, AZT) was shown to induce genome-wide DNA hypermethylation, low-frequency silencing of thymidine ... -
Identification of a circular intermediate in the transfer and transposition of Tn4555, a mobilizable transposon from Bacteroides spp.
(East Carolina University, 1993-05)Transmissible cefoxitin (FX) resistance in Bacteroides vulgatus CLA341 was associated with the 12.5-kb, mobilizable transposon, Tn4555, which encoded the 13-lactamase gene cfxA. Transfer occurred by a conjugation-like ... -
Genetic and biochemical analysis of a novel Ambler class A β-Lactamase responsible for cefoxitin resistance in Bacteroides species.
(East Carolina University, 1993-05)A clinical isolate of Bacteroides vulgatus was resistant to tetracycline, clindamycin, ampicillin, cephaloridine, cefoxitin, and other 13-lactam antibiotics except imipenem. 13-Lactam resistance was mediated by a ... -
Autocrine production of extracellular catalase prevents apoptosis of the human CEM T-cell line in serum-free medium.
(East Carolina University, 1993-05-15)CCRF-CEM is a human T-cell line originally isolated from a child with acute lymphoblastic leukemia. At cell densities > 2 x 10 cells per ml, CEM cells grow in serum-free medium, but at lower cell densities the cultures ... -
Purification and Partial Characterization of Relaxin and Relaxin Precursors from the Hamster Placenta
(East Carolina University, 1993-07)Previous immunological studies have indicated that the molecular structure of hamster relaxin is quite different from that of porcine relaxin. In the present study, hamster relaxin was purified from placentas and ... -
Characterization of a caldesmon fragment that competes with myosin-ATP binding to actin.
(East Carolina University, 1993-08)The protein caldesmon inhibits actin-activated ATP hydrolysis of myosin and inhibits the binding of myosin*ATP to actin. Afragment isolated from a chymotryptic digest of caldesmon contains features of the intact molecule ... -
