Diallyl disulfide (DADS) has been demonstrated to exert potent anticancer effects in vitro and in vivo. Previous studies indicate that DADS may induce the differentiation and/or apoptosis of human leukemia cells in vitro. However, the mechanisms underlying these anticancer effects remain elusive. The aim of the present study was to investigate alterations in the subcellular localization of prot...

In this paper, we discuss the design and implementation of D’Groove, an intelligent Disc Jockey (DJ) system that uses a haptic turntable for controlling the playback of digital audio. We begin by describing the tasks of a DJ and defining some of the challenges associated with the traditional DJ process. We then introduce our new system, discussing how it improves auditory navigation for DJs and...

Mutations in the DJ-1 gene were recently identified in an autosomal recessive form of early-onset familial Parkinson disease. Structural biology, biochemistry, and cell biology studies have suggested potential functions of DJ-1 in oxidative stress, protein folding, and degradation pathways. However, animal models are needed to determine whether and how loss of DJ-1 function leads to Parkinson d...

The Parkinson's disease-related protein DJ-1 has a role in the protection against oxidative stress and maintenance of mitochondria structure. Whether this action depends on its localization and activity within the mitochondria is not clear. Here we develop an approach to resolve intra-mitochondrial distribution of DJ-1 and monitor its translocation under specific conditions. By a new split-gree...

Oxidative stress, which is associated with an increased concentration of reactive oxygen species (ROS), is involved in the pathogenesis of numerous diseases including cancer. In response to increased ROS levels, cellular antioxidant molecules such as thioredoxin, peroxiredoxins, glutaredoxins, DJ-1, and superoxide dismutases are upregulated to counteract the detrimental effect of ROS. However, ...

Oxalate crystals and other types of crystals are the cause of urolithiasis, and these are related to oxidative stress. The search for new compounds with antioxidant qualities and inhibitors of these crystal formations is therefore necessary. In this study, we extracted four sulfated polysaccharides, a fucoglucoxyloglucuronan (DJ-0.3v), a heterofucan (DJ-0.4v), and two glucans (DJ-0.5v and DJ-1....
