Multiantenna wireless systems have shown great promise in achieving high rates. We consider an OFDM multiple transmit/receive antenna system. We propose a linear non-redundant block pre-coding scheme, that is applied at the input of the OFDM system. The coding spreads the symbols of each user over all subcarriers, thus increasing multipath diversity, and at(More)
OBJECTIVE To study the effect of extract of Ginkgo bilboa leaf (EGB) on renal lesions of early diabetic nephropathy (DN). METHODS Sixty-eight patients with early DN were randomly divided into two groups, the control group (34 patients) and the treated group (34 patients). Patients in both groups received conventional therapy, while additional 9.6 mg EGB(More)
OBJECTIVE To identify the pathogenic mutations of phenylalanine hydroxylase gene (PAH) in patients with phenylketonuria (PKU) from Hebei Province. METHODS Genomic DNA was extracted from 55 unrelated PKU patients from September 2007 to July 2009. All PAH exons and exon-intron junctions were amplified by polymerase chain reaction (PCR) and sequenced.(More)
Esophageal squamous cell carcinoma (ESCC) is the most common type of esophageal carcinoma and remains the leading cause of cancer-related death worldwide. DEAD-box RNA helicases play critical roles in cellular metabolism and in many cases have been implicated in cellular proliferation and neoplastic transformation. DDX46 belongs to DEAD-box helicase family,(More)
