We investigated hellandite-group mineral phases from the Roman Region, alkali syenite ejecta, by multimethod analyses. They show a complex crystallisation history including co-precipitation of hellandite-(Ce) with brockite, resorption, sub-solidus substitution mottanaite-(Ce), exsolution perthite-like ferri-mottanaite-(Ce), overgrowth an oscillatory-zoned euhedral shell ferri-mottanaite-(Ce) an...

The aim of this study was to investigate the effect of prior exercise on the heart rate (HR) and oxygen uptake (VO2) off-kinetics after a subsequent high-intensity running exercise. Thirteen male futsal players (age 22.8±6.1years) performed a series of high-intensity bouts without prior exercise (control), preceded by a prior same intensity continuous exercise (CE+CE) and a prior sprint exercis...

In keeping with the Congressional Budget Office (CBO) definition of CE (“. . .a rigorous evaluation of the impact of different options that are available for treating a given medical condition for . . . a set of patients”) and the experience of several nations, the authors reviewed CE as applied to medical devices and drugs, surgical interventions, and diagnostic tests. Their examination focuse...

BACKGROUND Compulsive exercise (CE) has been proposed as significant in the etiology, development and maintenance of eating disorders (EDs), resulting in more severe and enduring pathology. However, few studies have investigated CE longitudinally in adolescents with EDs. We aimed to test if adolescents show the same associations between CE and other clinical variables as previous research has f...

background: reactive oxygen species (ros) have important role in the etiology and pathogenesis of rheumatoid arthritis (ra). we investigated the effect of conjugated linoleic acids (clas) and vitamin e on lipid peroxidation. methods: in a randomized, double-blind placebo, controlled, clinical trial 87 patients with active ra were enrolled. they were divided into 4 groups, received one of the fo...

The plexin family transmembrane proteins are putative receptors for semaphorins, which are implicated in the morphogenesis of animal embryos, including axonal guidance. We have generated and characterized putative null mutants of the C. elegans plexinA gene, plx-1. plx-1 mutants exhibited morphological defects: displacement of ray 1 and discontinuous alae. The epidermal precursors for the affec...

Parasitic nematodes of humans and plants secrete a structurally novel type of fatty acid- and retinol-binding protein, FAR, into the tissues they occupy. These proteins may interfere with intercellular lipid signaling to manipulate the defense reactions of the host or acquire essential lipids for the parasites. The genome of the nematode Caenorhabditis elegans encodes eight FAR-like proteins (C...
