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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Neurogenic inflammation and sensitivity to environmental chemicals.
(East Carolina University, 1993-08)Neurogenic inflammation as a pathway distinct from antigen-driven, immune-mediated inflammation may play a pivotal role in understanding a broad class of environmental health problems resulting from chemical exposures. ... -
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 ... -
Prenatal diagnosis of a giant intracranial teratoma associated with pulmonary hypoplasia.
(East Carolina University, 1993-10)We present a case in which an intracranial tumour replacing all intracranial contents was diagnosed by sonography at 31 weeks' gestation. The patient was delivered by caesarean section and died shortly after delivery. At ... -
Cloning and characterization of the endogenous cephalosporinase gene, cepA, from Bacteroides fragilis reveals a new subgroup of Ambler class A beta-lactamases.
(East Carolina University, 1993-11)Bacteroides frgiglis CS30 is a clinical isolate resistant to high concentrations of benzylpenicillin and cephaloridine but not to cephamycin or penem antibiotics. beta-Lactam resistance is mediated by a chromosomally encoded ... -
Stereotypes of Stutterers and Nonstutterers in Three Rural Communities in Newfoundland
(East Carolina University, 1993-12)The existence of a negative stereotype of stutterers among residents of three Small, rural communities in Newfoundland, Canada was investigated. Members of these communities (n=106) completed a 25 item semantic differential ... -
Cardiac tamponade and pericardial disorders in connective tissue diseases: case report and literature review.
(East Carolina University, 1994-02)Pericardial disorders occurring in connective tissue diseases are not uncommon and may present as acute or chronic pericarditis with or without an effusion. In many instances, a diagnosis of pericardial involvement is not ... -
Method of treating asthma using IL-8
(1994-03-01)A method of treating asthma in a subject in need of such treatment comprises contacting Interleukin-8 or an active fragment thereof to the respiratory epithelium of the subject. The active agent is preferably human endothelial ... -
Lymphocytic hypophysitis.
(East Carolina University, 1994-05)LYMPHOCYTIC HYPOPHYSITIS is an unusual disorder that nearly exclusively affects women; fewer than 50 cases have been reported in the literature. The present case also is unusual because a normal computed tomographic (CT) ... -
