BACKGROUND Previous work demonstrated that a soy-dairy protein blend (PB) prolongs hyperaminoacidemia and muscle protein synthesis in young adults after resistance exercise. OBJECTIVE We investigated the effect of PB in older adults. We hypothesized that PB would prolong hyperaminoacidemia, enhancing mechanistic target of rapamycin complex 1 (mTORC1) signaling and muscle protein anabolism com...

IN THEIR PERSPECTIVES ARTICLE, Miller and Hamilton (6) propose that the term “mitochondrial biogenesis” be limited to the measurement of the synthesis rate of mitochondrial proteins. For support, they cite evidence that changes in the abundance of transcription factors for mitochondrial genes or the mRNAs encoding mitochondrial proteins may not result in corresponding changes in mtDNA or protei...

Abstract Three interferometers (the Sagnac sensor, the linear polarization interferometer, and reflecting interferometer) incorporated with bow tie fiber are proposed to detect seawater temperature. Bow fiber, a kind of maintaining has stress induced birefringence. The three categorized as transmission reflection types analyze sensing principles. Related experiments performed explore influence ...

1. In Expt 1, fractional synthesis rates (FSR) of tissue protein were measured along the gastrointestinal tract (GIT) of six 1-week-old, milk-fed lambs by using a large amount of L-[3,4(n)-3H]valine. 2. In Expt 2, eighteen lambs were used to determine the fractional growth rate (FGR) of gastrointestinal tissue protein. 3. FSRMinimum (Min) and FSRMaximum (Max) were calculated assuming plasma or ...

We are conducting a large program to classify newly discovered Milky Way star cluster candidates from the list of Froebrich, Scholz & Raftery (2007b). Here we present deep NIR follow-up observations from ESO/NTT of 14 star cluster candidates. We show that the combined analysis of star density maps and colour-colour/magnitude diagrams derived from deep near-infrared imaging is a viable tool to r...

Mobile Ad hoc NETwork (MANET) is a collection of mobile nodes that are arbitrarily located so that the interconnections between nodes are dynamically changing. In MANET mobile nodes forms a temporary network without the use of any existing network infrastructure or centralized administration. A routing protocol is used to find routes between mobile nodes to facilitate communication within the n...

We determined whether essential amino acid and carbohydrate supplementation could offset the catabolic response to prolonged inactivity. Major outcome measures included mixed muscle fractional synthetic rate (FSR), phenylalanine net balance, lean leg mass, and leg extension strength. On d 1 and 28, vastus lateralis muscle biopsies and femoral arterio-venous blood samples were obtained during a ...

The purpose of the present study was to determine the effect of acute administration of insulin-like growth factor I (IGF-I) or insulin on in vivo protein synthesis in muscle and other organs in fasted mice and to compare this response with that produced by feeding. Recombinant IGF-I (3.3 nmol prime, 3.33 nmol/h) or insulin (0.056 nmol/h) was infused intravenously for 60 min along with glucose ...

A method for canopy Fluorescence Spectrum Reconstruction (FSR) is proposed in this study, which can be used to retrieve the solar-induced canopy fluorescence spectrum over the whole chlorophyll fluorescence emission region from 640–850 nm. Firstly, the radiance of the solar-induced chlorophyll fluorescence (Fs) at five absorption lines of the solar spectrum was retrieved by a Spectral Fitting M...

Here, we have described and validated a strategy for monitoring skeletal muscle protein synthesis rates in rodents and humans over days or weeks from blood samples. We based this approach on label incorporation into proteins that are synthesized specifically in skeletal muscle and escape into the circulation. Heavy water labeling combined with sensitive tandem mass spectrometric analysis allowe...
