Edwards, L. J., J. R. McFarlane, K. G. Kauter, and I. C. McMillen. Impact of periconceptional nutrition on maternal and fetal leptin and fetal adiposity in singleton and twin pregnancies. Am J Physiol Regul Integr Comp Physiol 288: R39–R45, 2005. First published June 10, 2004; doi:10.1152/ajpregu.00127.2004.—It has been proposed that maternal nutrient restriction may alter the functional develo...

BACKGROUND Individual participant data (IPD) from completed clinical trials should be responsibly shared to support efficient clinical research, generate new knowledge and bring benefit to patients. The Medical Research Council (MRC) Hubs for Trials Methodology Research (HTMR) has developed guidance to facilitate the sharing of IPD from publicly funded clinical trials. METHODS Development of ...

Development and application of measurement methods is an integral part of the Polymers Division's projects. Examples in process monitoring, combinatorial methods and neutron scattering are depicted on the cover. Upper left composite On-line stroboscopic microscopy captures the action of processing additives during the extrusion of polyethylene. The polyethylene is forced under the action of a t...

The rate coefficient, k, of the reaction is, however, the same as for R34 of WAE, i.e., k = 3.6 10 12 cm s . The above correction in R34 impacts the SO2 abundance and lifetime somewhat, as discussed below. [2] Once in the atmosphere, SO2 is photodissociated to produce SO, which is further photodissociated to form sulfur atoms. The reaction of SO with O2 or OH recycles sulfur atoms back to SO2 (...

The structures of cytoplasmic peptidoglycan precursor and mature peptidoglycan of an isogenic series of Staphylococcus haemolyticus strains expressing increasing levels of resistance to the glycopeptide antibiotics teicoplanin and vancomycin (MICs, 8 to 32 and 4 to 16 microg/ml, respectively) were determined. High-performance liquid chromatography, mass spectrometry, amino acid analysis, digest...

A permutation π of an abelian group G (that is, a bijection from G to itself) will be said to avoid arithmetic progressions if there does not exist any triple (a, b, c) of elements of G, not all equal, such that c − b = b − a and π(c) − π(b) = π(b) − π(a). The basic question is, which abelian groups possess such a permutation? This and problems of a similar nature will be considered. 1 Notation...

CENTA, a chromogenic cephalosporin, is readily hydrolyzed by β-lactamases of all classes except for the Aeromonas hydrophila metalloenzyme. Although it cannot practically be used for the detection of β-lactamaseproducing strains on agar plates, it should be quite useful for kinetic studies and the detection of the enzymes in crude extracts and chromatographic fractions. Nitrocefin and, to a les...
