We report here on the cloning and functional characterization of human SVCT2, a sodium-dependent vitamin C (ascorbate) transporter. The hSVCT2 cDNA obtained from a human placental choriocarcinoma cell cDNA library, codes for a protein of 650 amino acids with a predicted molecular mass of 70 kDa. At the level of amino acid sequence, the human SVCT2 exhibits(More)
We have isolated a cDNA from human placenta, which, when expressed heterologously in mammalian cells, mediates the transport of the water-soluble vitamin thiamine. The cDNA codes for a protein of 497 amino acids containing 12 putative transmembrane domains. Northern blot analysis indicates that this transporter is widely expressed in human tissues. When(More)
We report here on the cloning and functional characterization of human Na(+)-dependent vitamin C transporter 1 (SVCT1). The human SVCT1 cDNA, obtained from a Caco2 cell cDNA library, encodes a protein of 598 amino acids with 12 putative transmembrane domains. The SVCT1-specific transcript, 2.4 kb in size, is expressed in kidney, liver, small intestine,(More)
The present work was carried out to diagnose the inclusion body hepatitishydropericardium syndrome (IBH-HPS) in broiler chicks using conventional technique. Materials were collected from a private broiler farm during outbreak at the age of 25 days. The clinical signs were recorded. Grossly, liver was pale, friable, enlarged with the presence of focal or(More)
In this paper, we propose new non-coherent spacetime block code (STBC) designs, which achieve full transmit diversity as well as high rates. We first present a search procedure to generate full-diversity non-coherent unitary space-time codebooks for any number of transmit antennas (nt) and time slots (T ≥ 2nt), using radial coordinates of points lying on(More)
In this paper, we consider a slow-fading n<inf>t</inf> &#x00D7;n<inf>r</inf> multiple-input multiple-output (MIMO) channel subjected to block fading. Reliability (in terms of achieved diversity order) and rate (in number of symbols transmitted per channel use) are of interest in such channels. We propose a new precoding scheme which achieves both full(More)
