Pandangan Generasi Muda Anggota Perkumpulan Tàijí di Surabaya terhadap Tàijí 泗水太极俱乐部青年成员对太极拳的看法

Adanya fenomena bahwa olahraga tàijí lebih disukai oleh orang-orang tua, sementara orang muda lebih menyukai olahraga lain. Artikel ini meneliti tentang alasan generasi muda Surabaya tertarik mengikuti kegiatan tàijí dan hubungan olahraga tàijí dengan kesehatan manusia serta budaya Tionghoa. Kajian pustaka meliputi pengertian tàijí, penyakit-penyakit sistem peredaran darah; sistem saraf; sistem pencernaan, dan pengaruh tàijí terhadap kesehatan secara menyeluruh, pengertian filosofi Konfusianisme. Menggunakan metode pendekatan kualitatif deskriptif dengan wawancara semi terstruktur. Hasil penelitian menemukan walaupun usia responden penelitian masih muda, tetapi tertarik berolahraga tàijí, karena mencontoh orang tua mereka atau membaca buku atau ingin mendalami gerakan-gerakan yang lambat dari tàijí. Mereka juga mengetahui bahwa olahraga tàijí dapat menyehatkan tubuh, terutama sifat gerakan-gerakannya yang lambat. Jurus lambat dari tàijí ini berfungsi untuk penyelarasan fungsi organ vital tubuh manusia sesuai dengan filosofi kebudayaan Konfusianisme Tiongkok mengenai “ lǐ礼” dan “中庸zhōngyōng”

The Inflammatory Kinase MAP4K4 Promotes Reactivation of Kaposi's Sarcoma Herpesvirus and Enhances the Invasiveness of Infected Endothelial Cells

Kaposi's sarcoma (KS) is a mesenchymal tumour, which is caused by Kaposi's sarcoma herpesvirus (KSHV) and develops under inflammatory conditions. KSHV-infected endothelial spindle cells, the neoplastic cells in KS, show increased invasiveness, attributed to the elevated expression of metalloproteinases (MMPs) and cyclooxygenase-2 (COX-2). The majority of these spindle cells harbour latent KSHV genomes, while a minority undergoes lytic reactivation with subsequent production of new virions and viral or cellular chemo- and cytokines, which may promote tumour invasion and dissemination. In order to better understand KSHV pathogenesis, we investigated cellular mechanisms underlying the lytic reactivation of KSHV. Using a combination of small molecule library screening and siRNA silencing we found a STE20 kinase family member, MAP4K4, to be involved in KSHV reactivation from latency and to contribute to the invasive phenotype of KSHV-infected endothelial cells by regulating COX-2, MMP-7, and MMP-13 expression. This kinase is also highly expressed in KS spindle cells in vivo. These findings suggest that MAP4K4, a known mediator of inflammation, is involved in KS aetiology by regulating KSHV lytic reactivation, expression of MMPs and COX-2, and, thereby modulating invasiveness of KSHV-infected endothelial cells. © 2013 Haas et al

Scale-adaptive simulation (SAS) of dynamic stall on a wind turbine

Scale-adaptive simulation (SAS) approach is employed to investigate the complex dynamic stall phenomena occurring on a wind turbine blade. The results are com-pared with the more popular less computationally-expensive unsteady Reynolds-averaged Navier-Stokes (URANS) approach where the latter is validated using three sets of experimental data. The comparison reveals that the two approaches have similar predictions of the instant of the formation/bursting/shedding of the laminar separation bubble (LSB) and dynamic stall vortex (DSV), the size of the LSB and aerodynamic loads during the upstroke. This is while the two approach-es exhibit dissimilar predictions of the trailing-edge vortex characteristics, its in-teraction with the DSV, number of secondary vortices and aerodynamic loads during the downstroke
