Plasmon is the quantum of the collective oscillation of electrons. How plasmon loses its energy (or damping) plays a pivotal role in plasmonic science and technology. Graphene plasmon is of particular interest, partly because of its potentially low damping rate. However, to date, damping pathways have not been clearly unravelled experimentally. Here, we(More)
Apoptosis signal-regulating kinase 1 (ASK1) is activated by various stresses. The link between ASK1 activation and endoplasmic reticulum (ER) stress, two causal events in diabetic embryopathy, has not been determined. We sought to investigate whether ASK1 is involved in the unfolded protein response (UPR) that leads to ER stress. Deleting Ask1 abrogated(More)
OBJECTIVE To investigate the efficacy and safety of Chinese herbal medicines in the treatment of patients with vascular dementia. DATA RETRIEVAL We retrieved publications from Cochrane Library (2004 to July 2011), PubMed (1966 to July 2011), the Chinese Science and Technique Journals Database (1977 to July 2011), the China National Knowledge(More)
A process for fabricating dense graphene nanoribbon arrays using self-assembled patterns of block copolymers on graphene grown epitaxially on SiC on the wafer scale has been developed. Etching masks comprising long and straight nanoribbon array structures with linewidths as narrow as 10 nm were fabricated, and the patterns were transferred to graphene. Our(More)
Dysregulation of SOX10 was reported to be correlated with the progression of multiple cancer types, including melanocytic tumors and tumors of the nervous system. However, the mechanisms by which SOX10 is dysregulated in these tumors are poorly understood. In this study, we report that SOX10 is a direct substrate of Fbxw7α E3 ubiquitin ligase, a tumor(More)
Grain size effects on the physical properties of polycrystalline ferroelectrics have been extensively studied for decades; however there are still major controversies regarding the dependence of the piezoelectric and ferroelectric properties on the grain size. Dense BaTiO3 ceramics with different grain sizes were fabricated by either conventional sintering(More)
Since the first report of promising electrical properties of Molybdenum disulfide (MoS2) transistors in 2011, two-dimensional materials with unique properties have attracted great attention, and much research on their applications has been carried out. MoS2 and black phosphorus are excellent candidates for advanced applications in future electronics because(More)
BACKGROUND AND AIM Inotropes are commonly used to treat myocardial dysfunction, which is the major complication after coronary artery bypass graft (CABG). Milrinone, a phosphodiesterase 3 inhibitor, is one of these inotropes. Recently, a number of clinical studies have been carried out to evaluate the effects of milrinone on cardiac function in patients(More)
