Nickel‐Catalyzed Regio‐ and Stereoselective Reductive Alkylative Cyclization of 1,6‐Enynes with Alkyl Bromides

Yunxin Xing, Zhu Tian, Kun Shen

Advanced Synthesis & Catalysis > 366 > 18 > 3802 - 3807

A nickel‐catalyzed reductive alkylative cyclization of 1,6‐enynes with alkyl bromides has been developed. This transformation avoids the use of stoichiometric organometallic reagents and introduces alkyl groups regio‐ and stereoselectively into the products. This method provides a platform for the synthesis of carbo‐ and heterocycles that are widely found in many natural products and biologically...

Chronic treatment with levetiracetam reverses deficits in hippocampal LTP in vivo in experimental temporal lobe epilepsy rats

Yu-Xing Ge, Xiang-Zhu Tian, Ying-Ying Lin, Xue-Yuan Liu

Neuroscience Letters > 2016 > 628 > C > 194-200

Temporal lobe epilepsy (TLE), the common form of epilepsy in adults, often displays complex partial seizures and cognitive deficits. The underlying mechanisms of such deficits are not yet well understood. Many contributing factors, such as initial epileptogenic lesion, seizure type, age of onset, and treatment side effects have been proposed. Levetiracetam (LEV) is a novel anti-epileptic drug (AED)...

Chenggang Clarence Yan, Hui Yu, Weizhi Xu, Yingping Zhang, more

Frontiers of Computer Science > 2015 > 9 > 3 > 431-441

It is an important task to improve performance for sparse matrix vector multiplication (SpMV), and it is a difficult task because of its irregular memory access. General purpose GPU (GPGPU) provides high computing ability and substantial bandwidth that cannot be fully exploited by SpMV due to its irregularity. In this paper, we propose two novel methods to optimize the memory bandwidth for SpMV on...
