Recent research reveals that playing prosocial video games increases prosocial cognitions and helpful behaviors [Gentile el al., 2009; Greitemeyer and Osswald, 2009; 2010; 2011]. These results are consistent with social-cognitive models of social behavior [e.g., the "General Learning Model," Buckley and Anderson, 2006]. The social-cognitive learning models suggest that in ...

We report a uniquely high yielding, general and practical ortho-bromination and iodination reaction of different classes of aromatic compounds. This reaction occurs by Rh(III)-catalyzed C-H bond activation methodology and is therefore the first example of the application of this cationic catalyst for C-Br and C-I bond formation.

Addition of O(2) enables the liquid-phase hydrogenation of phenol using H(2) at low temperatures under atmospheric pressure with an unexpected selectivity towards 2-cyclohexene-1-one rather than cyclohexanone. As a catalyst, as-synthesized Pd/MCM-41 including the residual templates within the mesoporous channels exhibits a prominent positive effect on the catalytic performance.

We have developed an integrated microfluidic immunoassay chip for high-throughput sandwich immunoassay tests. The chip creates an array of reactive patterns through mechanical protection by actuating monolithically embedded button valves. We have demonstrated that this chip can achieve highly sensitive immunoassay tests within an hour, and requires only microliter samples.

Osteoclasts are differentiated from hematopoietic stem cells and become multinucleated giant cells through cell-fusion by a number of regulators. Among such regulators, transcription factors play pivotal roles by reorganizing gene networks. Recently, epigenetic regulators like histone modifiers and chromatin remodelers have emerged to be prerequisite for gene regulations by transcriptional ...

Osteoclasts are multinuclear fusion cells derived from monocyte and macropharge lineage cells, which are differentiated in the presence of M-CSF and RANKL. Some transcription factors, such as NFATc1, are known to be associated with osteoclastogenesis however, the epigenetic regulation is not uncovered. Recently it was revealed that the activation and ...

Optimizing kidney preservation is a primary issue in transplantation, particularly in relation to new donor sources, such as expanded criteria donors (ECDs) and donation after cardiac death (DCD). Kidneys from these donors are highly sensitive to ischemia-reperfusion injuries-the emblematic lesions encountered during transplantation. Despite years of research, static cold storage, ...
