The methylation status of the adenine and cytosine residues in the genome of Plasmodium falciparum was studied using restriction enzymes exhibiting differential activity dependent on the methylation state of these residues in their recognition site. The gene coding for the enzyme dihydrofolate reductase-thymidylate synthase was studied for that purpose. No methylated adenine residues were observed in this gene in four strains tested. However, partial methylation of cytosine residues was observed ...

We undertook a study to determine the effects of four routes of administation on the efficacy of midazolam for premedication.In a randomized double-blind study, 119 unmedicated children, ASA I-II, aged 1.5-5 years, who were scheduled for minor elective surgery and who had been planned to received midazolam as a premedicant drug, were randomly assigned to one of four groups. Group I received intranasal midazolam 0.3 mg.kg-1; group II, oral midazolam 0.5 mg x kg(-1); group III, rectal midazolam 0. ...

RAS mutations are common in myeloid malignancies; however, it is not known whether oncogenic RAS can initiate leukemia. We show that expressing mutant K-Ras G12D protein from the endogenous murine locus rapidly induces a fatal myeloproliferative disorder with 100% penetrance characterized by tissue infiltration, hypersensitivity to growth factors, and hyperproliferation. Hematopoietic cells from diseased mice demonstrated increased levels of Ras-GTP, but effector kinases were not constitutively ...

Free radicals have been implicated in the pathogenesis of experimental autoimmune uveoretinitis (EAU). Nitroxides are stable radicals with a superoxide-dismutase-mimicking activity, which exert an anti-inflammatory effect in various animal models of oxidative damage and inflammation, such as experimental colitis and head trauma. We examined the use of the SOD mimic nitroxide 4-hydroxy-2,2,6,6,-tetramethylpiperidine-1-N-oxyl (TPL) to suppress EAU. Adult male Lewis rats were immunized with 125 microg/ ...

We design an experiment to understand how social preferences affect investment decisions through stock allocations and probability assessments. The major preference channel is asymmetric in social outcomes – although negative and positive responsible investment (RI) externalities have the same magnitudes, negative externalities have greater impact on investment choices. The effect is persistent, but heterogenous. We also find asymmetries in belief formation and learning constitute a secondary channel. ...

The main goal of this note is to introduce the notion of collection dependent “same context words”. Two (or more) words are the “same context words” if they occur in the same (or similar) context across a given text collection. Each word w in the collection is associated with a profile P(w). The profile P(w) is the set of words occurring in sentences that contain w. We introduce a distance function in the set profiles, and use it to cluster words. Words contained in the same cluster are “same context ...

Cigarette smoking is associated with consistent changes in small arteries and arterioles. Recently, arterial compliance was determined in smokers; however, the effect of smoking cessation on arterial compliance has not yet been investigated. The objective of the study was to assess how smoking cessation, achieved with use of behavioral and pharmacologic therapy, influences vascular compliance and arterial stiffness in smokers. In an open-label study, 60 habitual smokers were treated for 2 months ...

Background Obesity is characterized by insulin resistance and hyperinsulinemia that may elevate arterial pressure due to sympathetic overactivity and volume overload. The aim of the study is to measure hemodynamic parameters and metabolic variables in obese normotensive subjects. Methods Twenty-four normotensive, overweight subjects from our medical staff were enrolled. They had personal and group meetings with a physician, dietician, and psychologist to improve their compliance with regard to physical ...

Mathematics Research Report 93-06, University of Maryland Baltimore County] for multiaffine mappings, and provide computationally tractable necessary and sufficient robust stability conditions for quasipolynomials with interval ...

A family of linear systems with uncertainties in parameters and delays, and its corresponding family of characteristic quasipolynomials, are considered. Both commensurate and non-commensurate delays are considered. It is shown that for a large class of systems, namely those which comply with a simple condition ensuring no degree reduction, Hurwitz stability implies also exponential stability.

AIMS To determine normal concentrations of 17α-hydroxyprogesterone (17OHP) for premature infants. METHODS 17OHP was measured in 66 consecutive premature infants once a week during the first month, and once every two weeks thereafter, until the age of 3 months. The 17OHP values in 100 full term healthy neonates on the third day of life served as controls. Blood was sampled on filter paper using a neonatal radioimmunoassay kit. Findings were correlated with gestational age, birthweight, mode of delivery, ...

Evaluation of the damage severity in a mechanical system is required for the assessment of its remaining useful life. In rotating machines, bearings are crucial components. Hence, the estimation of the size of spalls in bearings is important for prognostics of the remaining useful life. Recently, this topic has been extensively studied and many of the methods used for the estimation of spall size are based on the analysis of vibrations. A new tool is proposed in the current study for the estimation ...
