Information on the determinants of dietary supplement (DS) use in France is largely lacking, especially in population subgroups such as smokers. Also, little is known about the role of health professionals in DS purchases. The aim of the present study was to describe DS use along with its sociodemographic, lifestyle and dietary correlates in a large sample of French adults (age 18+years) partic...

The aim of this study was to evaluate the influence of endogenous nitric oxide on resting microvascular tone in the Dahl salt-sensitive (DS) rat and to determine how this influence is altered in salt-induced hypertension. Intravital microscopy was used to examine the arteriolar network in the spinotrapezius muscle of DS rats maintained on low (0.45% NaCl) or high (4% NaCl) salt diets for 6-7 we...

A Gram-negative, non-motile, pale-yellow, rod-shaped bacterial strain, DS-42(T), was isolated from a soil in Korea and its taxonomic position was investigated by a polyphasic study. Strain DS-42(T) grew optimally at 25 degrees C and pH 7.0-8.0. Strain DS-42(T) did not form nodules on three different legumes, and the nodD and nifH genes were also not detected by PCR. Strain DS-42(T) contained Q-...

Previous studies have indicated that LLA-DR homozygous cell lines express two DR molecules but only a single DS (I-A-like) molecule. This report demonstrates that an HLA-DR5 homozygous cell line expresses at least two distinct DS molecules. These two DS molecules are formed by the association of a single DS alpha chain with either of two DS beta chains. Four distinct Ia molecules have now been ...

down's syndrome (ds) is the most common chromosomal abnormality in human. subjects with ds are known to be peridisposed to develop leukemia. the molecular basis of the association between ds and leukemia is unknown. the unscheduled dna synthesis (uds) test measure the ability of dna-repair in mammalian cells after excision of a stretch of dna containing the region of damage induced by chem...

This article describes the use of capillary electrophoresis (CE) to examine the influence of different cations (C(+); C(+) = Na(+) and tetra-n-alkylammonium, NR(4)(+), where R = Me, Et, Pr, and Bu) on the rates of denaturation of bovine carbonic anhydrase II (BCA) in the presence of anionic surfactant dodecylsulfate (DS(-)). An analysis of the denaturation of BCA in solutions of Na(+)DS(-) and ...

In previous studies, heroin was shown to engender cocaine-like discriminative stimulus (DS) effects; however, the mechanisms underlying the cocaine-like effects of heroin are unknown. The present study evaluated the extent to which the shared DS effects of heroin and cocaine involve common monoaminergic mechanisms of action. In squirrel monkeys discriminating cocaine (0.3 mg/kg) from saline, he...

This study reveals that the cold-sensitive (CS) + dry-sensitive (DS) corneal afferents reported in a previous study consist of two types: 1) low threshold (LT)-CS + DS neurons with <1°C cooling sensitivity, and 2) high threshold (HT)-CS + DS neurons with a wide range of cooling sensitivities (~1-10°C cooling). We also found DS neurons with no cooling sensitivity down to 19°C [cold-insensitive (...

The output units of fish retina, i.e., the retinal ganglion cells (detectors), send highly processed information to the primary visual centers of the brain, settled in the midbrain formation tectum opticum (TO). Axons of different fish motion detectors terminate in different tectal levels. In the superficial layer of TO, axons of direction-selective ganglion cells (DS GCs) are terminated. Singl...
