This research is an attempt to examine the ideological aspects of Korean cinema in the context of politico-economic changes. Korean cinema is in the process of economic restructuring, driven by neoliberal forces on a global scale. These economic forces also influence film texts on a concrete level, creating hybrid characters and narratives in blockbusters and co-produced films. These new genre films have tended to reinforce patriarchal ideology, making it increasingly pronounced, as Korean films become more technologically advanced and the production system globalized. To illustrate these effects, this article offers a textual analysis of Never Forever [Kim Jina 2007], which was the first U.S.–Korean co-production. 相似文献

Isoprostanes (IsoP) are formed by free radical catalyzed peroxidation of arachidonic acid independent of the cyclooxygenase enzyme. In the present study, we examined the effect of IsoP on norepinephrine (NE) release from the bovine isolated iris. Furthermore, we studied the role of IsoP's in hydrogen peroxide (H2O2)-induced enhancement of NE release from this tissue. Isolated bovine irides were prepared for studies of [3H]NE release using the superfusion method. Release of [3H]NE was induced via electrical field stimulation. Both 8-iso-prostaglandin E2 (E2-IsoP) and 8-iso-prostaglandin F2α (F2-IsoP) produced a concentration-related enhancement of field-stimulated [3H]NE release from isolated bovine irides, an effect that was mimicked by the thromboxane (Tx) receptor agonist, U46619 and by H2O2. The Tx-receptor antagonist, SQ 29548 inhibited responses to E2-IsoP (10μM) with an IC50 of 370±50 nM. SQ 29548 (10μM) also blocked the enhancement of electrically-evoked [3H]NE release induced by U46619 (10μM) but not that caused by H2O2 (300μM). The Tx synthetase inhibitor, carboxyheptylimidazole (10μM) prevented the stimulatory effect of E2-IsoP on evoked [3H]NE release without affecting responses induced by H2O2. We conclude that IsoP's can enhance sympathetic neurotransmission in the bovine isolated iris, an effect that can be blocked by a Tx-receptor antagonist. Furthermore, endogenously produced Tx's mediate the stimulatory effect of IsoP's on NE release. However, endogenously generated IsoP's or Tx's are not involved in H2O2-induced potentiation of sympathetic neurotransmission. 相似文献

The complete nucleotide sequence of an Indian isolate of Apple chlorotic leaf spot virus (ACLSV) was determined and found to be 7,525 nt in length. The genome organization was similar to known isolates of ACLSV, encoding three ORFs. Comparisons indicated high sequence variability among known isolates with overall nucleotide sequence identities of 80 to 84%. A striking variable region was identified among the replicase protein upstream of the RNA‐dependent RNA polymerase (aa 1510–1590), which showed a 41–43% match with the corresponding region in other isolates. Phylogenetic analysis at the nucleotide level clustered the isolates into three groups, without any relation to geographical origin. Recombination analysis showed that the isolate is a recombinant with recombination sites spread throughout the genome, especially in the polymerase gene region (nt 4700–5400). Most recombination sites were bordered by an upstream region (5′) of GC‐rich and downstream region (3′) of AU‐rich sequences of similar length. Correlation of recombination site with host type is discussed, and it was found that there were more interlineage recombinations in the apple host compared with intralineage recombinations. 相似文献

A series of novel monocarbonyl analogues of curcumin have been designed, synthesized and tested for their activity against Molt4, HeLa, PC3, DU145 and KB cancer cell lines. Six of the analogues showed potent cytotoxicity towards these cell lines with IC50 values below 1 μM, which is better than doxorubicin, a US FDA approved drug. Several analogues were also found to be active against both CQ-resistant (W2 clone) and CQ-sensitive (D6) strains of Plasmodium falciparum in an in-vitro antimalarial screening. This level of activity warrants further investigation of the compounds for development as anticancer and antimalarial agents. 相似文献
