Ceramide is a key compound in sphingolipid metabolism. Dynamics of ceramide synthesis is important in the several biological processes, such as induction of apoptosis or insulin resistance. So far, its de novo synthesis rate was evaluated indirectly, based on the content of the compound, its intermediates and the activity of respective enzymes. The aim of the present study was to directly measu...

We sought to determine whether exercise-induced muscle protein turnover alters the subsequent production of hepatically derived acute-phase plasma proteins, and whether age affects how these proteins are regulated. We measured arteriovenous (a-v) balance and the synthesis of mixed muscle protein, albumin (A) and fibrinogen (F) before exercise (REST) and from the beginning of exercise to 10, 60,...

OBJECTIVE Insulin stimulates albumin synthesis but inhibits that of fibrinogen in both type 1 diabetic and healthy subjects. In type 2 diabetes, fibrinogen production is increased both in the postabsorptive state and in response to hyperinsulinemia. No data exist on the rate of albumin synthesis and its response to insulin in type 2 diabetes. RESEARCH DESIGN AND METHODS We measured fractional...

We have previously identified a locus, fsr, a homologue of staphylococcal agr loci, which positively regulates the expression of gelatinase and serine protease (encoded by gelE and sprE, respectively) in Enterococcus faecalis OG1RF. The expression of the three genes in the fsr locus, fsrA, fsrB, and fsrC, appears to be autoregulated, and we have shown that mutants with insertion disruptions in ...

Face super-resolution (FSR), also known as face hallucination, which is aimed at enhancing the resolution of low-resolution (LR) images to generate high-resolution images, a domain-specific image problem. Recently, FSR has received considerable attention and witnessed dazzling advances with development deep learning techniques. To date, few summaries studies on learning-based are available. In ...

Op 12 januari 2023 trad de Verordening betreffende buitenlandse subsidies die interne markt verstoren (hierna: FSR (Foreign Subsidies Regulation)) in werking. Dit artikel bevat een overzicht van belangrijkste begrippen en instrumenten introduceert belicht enkele uitdagingen waarmee betrokkenen waarschijnlijk zullen worden geconfronteerd bij toepassing FSR.

Abstract: A generalized electromagnetic model is presented in order to predict the response of forward scatter radar (FSR) systems for air-target surveillance applications in both far-field and near-field conditions. The relevant scattering problem is tackled by developing the Helmholtz–Kirchhoff formula and Babinet’s principle to express the scattered and the total fields in typical FSR config...

Recently developed low-cost Global Positioning System (GPS) data loggers are promising tools for wildlife research because of their affordability for low-budget projects and ability to simultaneously track a greater number of individuals compared with expensive built-in wildlife GPS. However, the reliability of these devices must be carefully examined because they were not developed to track wi...

Feedback Shift Register (FSR) sequences have been successfully implemented in many communication systems for their randomness properties and ease of implementation. These include ranging and navigation systems, spread spectrum communication systems, CDMA mobile communication systems, and crypto systems such as streamciphers. This article gives a brief overview of FSR sequences, both linear and ...

We demonstrate optical frequency combs using the fluorite whispering gallery mode resonator as a nonlinear Kerr medium. Two regimes of generation are observed, giving the record low repetition rate of 13 GHz, equal to the cavity's free spectral range (FSR) or high repetition rates of multiples of cavity FSR. An intermediate regime was also observed. Raman lasing spectrum similar to modulation i...
