BACKGROUND Melanoma is an intractable cancer with a poor prognosis and increasing prevalence worldwide. Specific biomarkers for early diagnosis have yet to be found. MATERIALS AND METHODS Serum samples from melanoma patients and healthy volunteers were utilized for identifying melanoma marker proteins using a serological proteome approach. Specifically, G361 cell protein spots separated by 2-...
Atomic force microscopy-based nanoindentation is used to image and probe the local mechanical properties of thin disordered nanoparticle packings. The probed region is limited to the size of a few particles, and an individual particle can be loaded and displaced to a fraction of a single particle radius. The results demonstrate heterogeneous mechanical response that is location-dependent. The w...
Original scientific paper Given temporal variability of farmland, the coverage rate of wireless sensor network (WSN) is usually low. There may arise the problems of blind spot area and congestion of hot spots. We propose a coverage strategy for heterogeneous nodes in WSN based on temporal variability of farmland, which predicts the key nodes using key node prediction model according to temporal...
Virtual experience has begun to play a significant role in the marketing and promotion for the tourism industry. This article demonstrates that the advertising effects of traditional brochures vs. virtual experience would be contingent on consumers’ cognitive preferences. The traditional use of brochures in advertising would be more effective for verbalizers, whereas the virtual experience mode...
BACKGROUND Drop-off spots are locations in the proximity of primary schools where parents can drop off or pick up their child. From these drop-off spots children can walk to and from school. This pilot study aimed to investigate the feasibility and effectiveness of drop-off spots and to evaluate how drop-off spots are perceived by school principals, teachers and parents of 6-to-12-year old chil...
Solar lentigines are benign, brownish lesions that occur on light exposed skin surfaces from age 30 onwards, as a sign of photoaging. As they are of cosmetic importance to many patients, different therapeutic modalities have been tried to remove these unwanted spots. The recent development of short-pulsed, pigment-specific lasers has enabled physicians to selectively destroy the pigment within ...
Fas (CD95, APO-1, TNFRSF6) is a TNF receptor superfamily member that directly triggers apoptosis and contributes to the maintenance of lymphocyte homeostasis and prevention of autoimmunity. Although FADD and caspase-8 have been identified as key intracellular mediators of Fas signaling, it is not clear how recruitment of these proteins to the Fas death domain leads to activation of caspase-8 in...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
