Expression of GPCR fatty acid sensor/receptor genes in adipocytes is modulated by inflammatory mediators, particularly IL-1β. In this study we examined whether the IL-1 gene superfamily member, IL-33, also regulates expression of the fatty acid receptor genes in adipocytes. Human fat cells, differentiated from preadipocytes, were incubated with IL-33 at three different dose levels for 3 or 24 h and...
The application of distributed coding in many media applications, where low power and low-complexity encoder device is essential, is a new paradigm. In this paper, we propose a new pixel-domain Distributed Video Coding (DVC) scheme, in which both temporal and spatial correlations are exploited at the decoder. The Slepian-Wolf decoder is modified by introducing a source decoder to exploit Wyner-Ziv...
GPR41 is reportedly expressed in murine adipose tissue and mediates short chain fatty acid (SCFA)-stimulated leptin secretion by activating Gα i . Here, we agree with a contradictory report in finding no expression of GPR41 in murine adipose tissue. Nevertheless, in the presence of adenosine deaminase to minimise Gα i signalling via the adenosine A1 receptor, SCFA stimulated leptin...
Several recent contributions have demonstrated that Joint Source/ Channel (JSC) decoding could be a powerful technique to make error correction in the case of transmission of entropy encoded streams. This paper addresses a new scheme for JSC decoding of Arithmetic Codes (AC) based on Maximum A Posteriori (MAP) sequence estimation. The proposed algorithm performs Chase-like decoding using a priori...
The integration of arithmetic codes (AC) in the most recent coding standards for media applications motivated the development of joint source/channel (JSC) techniques for AC-encoded data. In this paper, we propose a low-complexity scheme which enables iterative decoding for serially concatenated AC and convolutional codes. Iterations are performed between soft input soft output (SISO) component decoders.
In recent years, the turbo principle has been widely applied to various decoding schemes. Here, we extend the general idea of iterative decoding to a communication scheme where arithmetic coding is used for source coding and a recursive systematic convolutional code is used for channel coding. The scope of this paper is to develop a low complexity SISO decoder for arithmetic codes using the SOVA algorithm...
Metformin (MET) is known to increase several biological effects of insulin (INS), but there is no information concerning its direct effects on protein synthesis. We studied the action of MET on albumin production by primary cultures of freshly isolated rat hepatocytes, alone or in combination with various agonists: INS, IGF-1, EGF, thyroxin, and dexamethasone. While having no effect alone, MET in...
