This research clearly outlines the supply chain in a process of evolution and digital transformation,where the collaboration of its members is concentrated,having technological tools to help chain *** analyze the advantages that this transformation produces in the supply chain,as well as its different processes,this study has a systemic perspective that involves precise elements for organizational development,such as the different phases of each process,operations,logistics,and *** must be borne in mind that any strategy in industrial companies grants the automation of procedures in the supply chain and determines a product in any phase of production,making the organization more sensitive to any variation in *** methodology included a bibliographic and non-experimental review that allows a descriptive and analytical study,which details the various characteristics of the fact that is being investigated,collecting information through interviews with different people who are involved with industrial *** the results obtained,it was identified that digital transformation helps reduce costs and generates greater *** conclusion,it was obtained that the digital supply chain helps in each of the phases of the processes,these are supervised by devices that help to have fast and effective information.

Noisy environments:untangling the role of anthropogenic noise on bird species richness in a Neotropical city

(–)-Epigallocatechingallate Interferes ranKL/ranK Signal Pathway and Induces Apoptosis during Osteoclastogenesis in RAW264 Cell

Food and Nutrition Sciences 2014年第2期5卷 107-116页

green tea catechin, (–)-epigallocatechin-3-gallate [(–)-EgCg], was found to increase osteogenic functioning in mesenchymal stem cells. This study qualified EgCg, the strongest inhibitory efficiency for receptor activator of nuclear factor-κB (NF-κB) ligand (ranKL)-activated osteoclastogenesis among other green tea catechins for RAW264, a murine preosteoclast cell line. Moreover, EgCg inhibited tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cell formation dose dependently in both single culture and co-culture systems, the expression of transcription factor, nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1) and some osteoclastic genes. Especially, EgCg exhibited a strong inhibitory effect on the expression levels of ranK, the receptor of ranKL, and oscar, a key co-stimulator of the ranKL/ranK signal. Simultaneously, apoptotic genes expression and Hoechst staining revealed that EgCg induced apoptosis in RAW264. Taken together, these data suggest that the inhibitory effect of EgCg to osteoclastogenesis is associated with a down regulation of ranKL/ranK signal, and increased apoptosis of preosteoclasts.
