Micro-geochemistry of the mantle and its volcanic rocks
… and Sr isotope variation in clinopyroxene (cpx), amphibole and melt from two spinel lherzolite xenoliths from the Middle Atlas Mountains, Morocco. These results support a multi-stage metasomatic process in which cpx and amphibole are recent additions to the lithospheric mantle, most recently …

Linkage studies of x-linked cleft palate and ankyloglossia in a British Columbia native kindred
… which segregate as a single X-linked trait (CPX) in a British Columbia (B.C.) Native kindred. The original description (Lowry 1970) of the clefting defect in the B.C. kindred included submucous cleft palate and bifid or absent uvula. Sixty-three of the B.C. family members were clinically …

Alternative splicing and RNA editing of the Complexin C-terminus regulates neurotransmitter release in Drosophila
… and memory. Functional regulation of Complexin (Cpx) provides an entry point for altering presynaptic output since the protein controls spontaneous and evoked neurotransmitter release through its effects on SNARE complex assembly. The Drosophila cpx locus undergoes alternative splicing to produce …

Analysis of a bacterial serine/threonine kinase
… significance. RdoA is a member of the Cpx regulon and its absence stimulates Cpx activation. Since the Cpx system is involved in regulating expression of cell surface appendages and is one of three envelope stress response systems, it is hypothesized that RdoA serves to relay Cpx …

Further characterisation of the envelope stress responses of Salmonella Typhimurium
… present the first comprehensive analysis of the Cpx regulated transcriptome in S. Typhimurium, identifying 116 genes as novel members of the S. Typhimurium Cpx regulon. Transcriptomic analyses, EMSAs and mutant screens further establish CpxAR as a major contributor to S. Typhimurium virulence …

Thermobarometry of Hawaiian Spinel Peridotites
… data, combined with preexisting clinopyroxene (cpx) and orthropyroxene major and trace element data, I have reconstructed the P-T range of the Hawaiian spinel peridotites using the Ca-in-olivine barometer and the cpx-opx thermometer (TBKN). To correctly apply the thermobarometric equations, I …

Synaptic structure and function at the Drosophila larval neuromuscular junction : a molecular analysis of complexin and radish
… and there is growing evidence that Complexin (Cpx), which binds to the SNARE complex with high affinity and 1:1 stoichiometry, can act as a vesicle fusion clamp. As suggested by its name, however, Cpx appears to play a more complex role in vesicle release, carrying out different functions in …

Foaming properties of whey protein isolate and [lambda]-carrageenan mixed systems
… 1) heated WPI and [lambda]C soluble complex (h-cpx), (2) heated WPI with added [lambda]C (pWPI - [lambda]C), and (3) unheated WPI with [lambda]C (WPI-[lambda]C). Foams were generated by beating the solution using a KitchenAid mixer. Foamability and foam stability were determined by measuring the …

Studio e validazione di una nuova metodica per la valutazione dello stato di forma
… used as a reference and it was a stress test (CPX). During the entire test, heart rate and gas exchange were recorded continuously; the second, the actual object of this study, was a submaximal test (TOP). Only heart rate was recorded continuously. The main purpose was to determinate an index …

The Relationship of Resting Cardiopulmonary Function to Peak and Submaximal Cardiopulmonary Exercise Testing in Older Adults with Heart Failure
… VO2peak and the VE/VCO2 slope, obtained during CPX, have been shown to be useful for monitoring the efficacy of symptom and therapeutic management. Peak cardiac output (Qpeak) would also be an excellent prognostic indicator but traditionally it has been difficult to measure since the measurement …

Structural Studies of Complexin/SNARE Interactions
… assembled SNARE complex. We demonstrated that Cpx-FL binds the t-SNARE complex SN1/SN3/Syx1a(188-259) in solution, as wa suggested for membrane-bound t-SNAREs. Note, however, that the t-SNARE complex does not contain the large complexin-binding interface provided by Syb2. Furthermore, we found …

A role for a predicted E. coli inner membrane lipoprotein in cell envelope integrity
… envelope stress response systems such as Rcs and Cpx cascades are upregulated in <em>E. coli</em> lacking the putative lipoprotein. Additionally, Cpx signaling is required for proliferation of the mutant under restrictive conditions. Further analyses suggest that the outer membrane protein …

Reliability of a semi-automated CO₂ rebreathing system for cardiac output measures during exercise
… using Defares’ exponential method (MedGraphics™ CPX/D system). Characteristics of the 19 female subjects were: (Mean and SD) age = 34.6 yr and 6.6 and V̇O₂pk= 32.8 mlkg⁻¹min⁻¹ and 9.5. The Q̇ trial consisted of 15 min of seated rest and 15 min of exercise. Values were determined in triplicate at …

Basalt petrogenesis beneath slow- and ultraslow-spreading Arctic mid-ocean ridges
… study was carried out measuring clinopyroxene (Cpx)melt and garnet (Gt)-melt partition coefficients during silica-poor garnet pyroxenite melting for a suite of trace elements, including U and Th, at 2.5GPa and 1420-1450°C. Partition coefficients range from 0.0083+0.0006 to 0.020+0.002 for Th and …

Caratterizzazione cardio metabolica di atleti in età evolutiva e confronto tra èlite e non èlite
… first to be performed was an incremental test (CPX) on the treadmill. Then after an average delay of a day, an all-out (AOT)test was carried out for the determination of the anaerobic component. The breathing pattern was measured using a portable metabolimeter (VO2000, Med Graphics, USA), and …
