Asymmetrical dimethylarginine (ADMA), an endogenous arginine analogue, inhibits nitric oxide synthases and plays important role in endothelial dysfunction.In the present study, we tested whether a novel genetic variant dimethylaminohydrolase 1 (DDAH1), ADMA hydrolyzing gene, was associated with stroke coronary heart disease (CHD) susceptibility Chinese Han population.By resequencing, identified 4-nucleotide deletion/insertion DDAH1 promoter. The insertion allele disrupted binding of...
<title>Abstract</title> The direct oxidation of methane into methanol exploiting O2 as oxidant offers an ideal route for utilization. Although the reaction is strongly preferred in thermodynamics, conventional catalytic systems always demand intense energy input like high temperatures or high-energy photons (>2.8 eV) to conquer large kinetic barrier conversion process. In this study, we demonstrate that by creation a suitable plasmonic photocatalyst, namely oxygen-vacancy-rich CuSeO3-x,...

Through approach, successfully conduct a 100-meter...
This Letter proposes a novel, to the best of our knowledge, approach utilizing delta-sigma modulation (DSM)-based 1-bit autoencoder (AE) for efficient encoding and decoding in various channel conditions. Simulation analysis demonstrates AE's ability mitigate noise by reducing peak-to-average power ratio (PAPR) enhancing an in-band signals, particularly under low signal-to-noise ratios (SNRs). The AE-DSM achieves theoretical transmission performance even at SNRs below 6 dB. In 40-m free-space...
