  • TALP-32 is highly basic protein with a molecular weight of 32 kDa purified from human term placenta. Some basic proteins such as defensins and cecropins are known to induce cell death by increasing membrane permeability and some of them are under development as an anticancer drug especially targeting multi-drug resistant cancers. Therefore, we investigated cytotoxic effect and mechanism of TALP-32 When HeLa cell was incubated with TALP-32, cytotoxicity was increased in time and dose dependent manner. As time goes by, HeLa cells became round and plasma membrane was ruptured. Increase of plasma membrane permeability was determined with LDH release assay. Also in transmission electron microscopy, typical morphology of necrotic cell death, such as cell swelling and intracellular organelle disruption was observed, but DNA fragmentation and caspase activation was not. And necrotic cell death was determined with Annexin V/Pl staining. The cytotoxicity of TALP-32 was minimal and decreased or RBC and Hep3B respectively. These data suggests that TALP-32 induces necrosis on rapidly growing cells but not on slowly growing cells implicating the possibility of its development of anticancer peptide drug.

  • The discussion was started from the question about how literary linguistic expressions are reproduced in the movies. This study focuses on the cinematized version of Jelinek's "Die Klavierspielerin", the by Michael Haneke. and looking for cinematization of literary works and these aesthetic values. The original delicately describes the life of Erika who has been living under the supervision and control by her mother. The topic of the is the conflict between the controlling mother and the desires of the heroin Erika who has been living under the suppression. The world of suppression symbolized by her mother is described as closed and dark space while the world of Erika and her desires, represented by Walter is described as open and bright space. The life of Erika living under control symbolized by prison-like double doors, iron-barred window, darkness and shadow is abnormally distorted. Even the piano that must be the center of her life as a pianist is also one of the symbols of dark world of suppression.

  • In 2010, only 14 tropical cyclones (TCs) were generated over the western North Pacific (WNP), which was the smallest since 1951. This study summarizes characteristics of TCs generated in 2010 over the WNP and investigates the causes of the record-breaking TC genesis. A long-term variation of TC activity in the WNP and verification of official track forecast in 2010 are also examined. Monthly tropical sea surface temperature (SST) anomaly data reveal that El Ni$\tilde{n}$o/Southern Oscillation (ENSO) event in 2010 was shifted from El Ni$\tilde{n}$o to La Ni$\tilde{n}$a in June and the La Ni$\tilde{n}$a event was strong and continued to the end of the year. We found that these tropical environments leaded to unfavorable conditions for TC formation at main TC development area prior to May and at tropics east of $140^{\circ}E$ during summer mostly due to low SST, weak convection, and strong vertical wind shear in those areas. The similar ENSO event (in shifting time and La Ni$\tilde{n}$a intensity) also occurred in 1998, which was the second smallest TC genesis year (16 TCs) since 1951. The common point of the two years suggests that the ENSO episode shifting from El Ni$\tilde{n}$o to strong La Ni$\tilde{n}$a in summer leads to extremely low TC genesis during La Ni$\tilde{n}$a although more samples are needed for confidence. In 2010, three TCs, DIANMU (1004), KOMPASU (1007) and MALOU (1009), influenced the Korean Peninsula (KP) in spite of low total TC genesis. These TCs were all generated at high latitude above $20^{\circ}N$ and arrived over the KP in short time. Among them, KOMPASU (1007) brought the most serious damage to the KP due to strong wind. For 14 TCs in 2010, mean official track forecast error of the Korea Meteorological Administration (KMA) for 48 hours was 215 km, which was the highest among other foreign agencies although the errors are generally decreasing for last 10 years, suggesting that more efforts are needed to improve the forecast skill.

  • Our previous study suggested that S-allylcysteine (SAC) inhibits the proliferation of the human cervical cancer cell line, HeLa, at least in part through the induction of apoptosis and cell cycle arrest. To further analyze the specific molecular mechanism(s) by which SAC mediates its antiproliferative effects, this study examined the role of SAC in regulating the protein expression of initiator caspase (caspase-9), effector caspases (caspase-3 and caspase-7), and poly-ADP-ribose polymerase (PARP) in HeLa. Western blot analysis showed that when cells were treated with 50 mM SAC for 48 hr, the expression of procaspase-3, -7, and -9 and PARP was reduced by 94%, 38%, 95%, and 64%, respectively, as compared to the untreated control. In contrast, the expression of caspase-3, -7, and -9 and cleaved-PARP was markedly increased by SAC treatment. The SAC-mediated changes in the expression of these proteins were correlated with the concomitant inhibition of cellular proliferation by SAC. The cell proliferation assay showed that HeLa treatment with more than 20 mM SAC for 6-48 hr resulted in both concentration- and time-dependent inhibition of cellular proliferation. These results indicate that the SAC-induced antiproliferative effect in HeLa may be mediated at least in part through the activation of caspase-9, followed by the activation of caspase-3 and caspase-7 as well as the inactivation of PARP, thus leading to cellular apoptosis.

  • Les positions qu'essait d'expliquer les $probl{\grave{e}}mes$ divers ${\grave{a}}$ propos de la $sexualit{\acute{e}}$, faisaient ressortir les points biologiques des actions $d^{\prime}{\hat{e}}tre$ humain par ${\acute{e}}volutionnisme$ plutot qu'explique les $probl{\grave{e}}mes$ de la nature humaine, $d{\acute{e}}sirs$ sexuelles, par les $sci{\acute{e}}t{\grave{e}}s$, les cultures et les'institutions. En face des questions des $possibilit{\acute{e}}s$ d'explications biologiques sur toutes les actions sexuelles, ils sont $plac{\acute{e}}s$ en crise. Le fait que $l^{\prime}{\hat{e}}tre$ humain est un'etre historique, n'implique pas ce qu'il est evolutionnaire. Pour cette raison, c'est difficile qu'on accepte le determisme biologique, $l^{\prime}{\acute{e}}volutionnisme$, sans conditions. En opposition avec cettes $id{\acute{e}}es$, Michel Foucault voudrait insister sur le fait de penser au sexe comme les $r{\acute{e}}sultats$ des productions sociologiques, politiques. Selon Foucault, la $sexualit{\acute{e}}$ n'est pas $donn{\acute{e}}$ de la nature que le pouvoir essaierait de mater, ou un domaine obscure que le savoir tendrait de $d{\acute{e}}voiler$, mais une sorte de dispositif historique. Donc, dans cet article, j'essaie d'examiner les processus, les differences, et les $probl{\grave{e}}mes$ entre les deux positions, puis je considere les limites philosophiques, des deux argumentations, et ses implications philosophique. Cela permet d'approcher ${\grave{a}}$ l'horizon divers du discours sexuelles de la $compr{\acute{e}}hension$.

  • Autoimmune arthritis, such as rheumatoid arthritis (RA), is a chronic inflammatory disorder that primarily affects the joints and then results in their progressive destruction. Effector Th cells have been classified as Th1 and Th2 subsets based on their cytokine expression profiles and immune regulatory function. Another subset of T cells termed Th17 was recendy discovered and known to selectively produce IL-17. Also, Th17 was shown to be generated by TGF${\beta}$ and IL-6 and maintained by IL-23. IL-17 is a proinflammatory cytokine that is considered to involve the development of various inflammatory autoimmune diseases such as RA, asthma, lupus, and allograft rejection. IL-17 is present in the sera, synovial fluids and synovial biopsies of most RA patient. IL-17 activates RA synovial fibroblasts to synthesize IL-6, IL-8 and VEGF via PI3K/Akt and NF-${\kappa}B$ dependent pathway. IL-17 increases IL-6 production, collagen destruction and collagen synthesis. In addition, it not only causes bone resorption but also increases osteoclastogenesis and fetal cartilage destruction. Inhibition of the IL-17 production may contribute a novel therapeutic approach along with potent anti-inflammatory effect and with less immunosuppressive effect on host defenses.

  • The objective of this study is to analyze rut resistance and moisture susceptibility of warm mix asphalt(WMA) mixture. The deformation strength ($S_D$), which is known to have high correlations with the high-temperature deformation resistance of dense grade mixture, was used as a tool, together with wheel tacking (WT) test, for evaluating warm mix asphalt mixture's rut resistance.
