To date, few studies have characterized the influence of energy deprivation on direct measures of skeletal muscle protein turnover. In this investigation, we characterized the effect of an acute, moderate energy deficit (10 d) on mixed muscle fractional synthetic rate (FSR) and associated intracellular signaling proteins in physically active adults. Eight men and 4 women participated in a 20-d,...

Quorum-sensing systems control major virulence determinants in Enterococcusfaecalis, which causes nosocomial infections. The E. faecalis quorum-sensing systems include several virulence factors that are regulated by the cytolysin operon, which encodes the cytolysin toxin. In addition, the E. faecalis Fsr regulator system controls the expression of gelatinase, serine protease, and enterocin O16....

Microresonator optical frequency combs based on cascaded four-wave mixing are potentially attractive as a multi-wavelength source for on-chip optical communications. In this paper we compare time domain coherence, radio-frequency (RF) intensity noise, and individual line optical communications performance for combs generated from two different silicon nitride microresonators. The comb generated...

Vehicular Ad-hoc Network (VANET) is used to provide the efficient network environment for a large vehicle system in which the vehicle speed is very fast. We provide the transmission of safety and non-safety messages among vehicles. If the message is receiving in less time so that the drivers can take the effective decision. For this purpose efficient safety message technique is used that is FSR...

It is presented a study of the dependence between free spectral range (FSR) and cavity length in Fabry-Perot interferometers. Furthermore, effect frequency modulation on FSR studied when an optical spectrum analyser (OSA) used as interrogator. For low it possible to observe this behaviour OSA using appropriate processing signal use white light interferometry technique.

Bacterial growth as a biofilm on solid surfaces is strongly associated with the development of human infections. Biofilms on native heart valves (infective endocarditis) is a life-threatening disease as a consequence of bacterial resistance to antimicrobials in such a state. Enterococci have emerged as a cause of endocarditis and nosocomial infections despite being normal commensals of the gast...

The goal of this study was to discover whether using different tracers affects the measured rate of muscle protein synthesis in human muscle. We therefore measured the mixed muscle protein fractional synthesis rate (FSR) in the quadriceps of older adults during basal, postabsorptive conditions and mixed meal feeding (70 mg protein x kg fat-free mass(-1) x h(-1) x 2.5 h) by simultaneous intraven...

16 Fractional synthesis rates (FSR) of tissue proteins (P) are usually measured using labeled amino 17 acid (AA) tracer methods over short periods of time under acute, particular conditions. In this work, 18 we developed a new isotopic approach, by combining the long-term and non-steady-state N 19 labeling of AA and P tissue fractions with compartmental modeling, in order to investigate the 20 ...

Fractional synthesis rates (FSR) of tissue proteins (P) are usually measured using labeled amino acid (AA) tracer methods over short periods of time under acute, particular conditions. By combining the long-term and non-steady-state (15)N labeling of AA and P tissue fractions with compartmental modeling, we have developed a new isotopic approach to investigate the degree of compartmentation of ...

The muscle protein fractional synthesis rate (FSR) is determined by monitoring the incorporation of an amino acid tracer into muscle protein during a constant-rate intravenous tracer infusion. Commonly two sequential muscle biopsies are obtained some time after starting the tracer infusion. However, other protocols, including those with an initial biopsy before starting the tracer infusion to m...
