<P><B>Background:</B></P><P>This study aims to evaluate the effectiveness of adenosine triphosphate-based chemotherapy response assay (ATP-CRA)-guided neoadjuvant chemotherapy for increasing resectability in patients with unresectable colorectal liver metastasis.</P><P><B>Patients and methods:</B></P><P>Patients were randomised into two groups: Group A was treated by conventional chemotherapy regimen and Group B was treated by chemotherapy regimen according to the ATP-CRA. Three chemotherapeutic agents (5-fluorouracil, oxaliplatin and irinotecan) were tested by ATP-CRA and more sensitive agents were selected. Either FOLFOX or FOLFIRI was administered. Between Group A and B, treatment response and resectability were compared.</P><P><B>Results:</B></P><P>Between November 2008 and October 2010, a total 63 patients were randomised to Group A (<I>N</I>=32) or Group B (<I>N</I>=31). FOLFOX was more preferred in Group A than in Group B (26 out of 32 (81.3%) <I>vs</I> 20 out of 31 (64.5%)). Group B showed better treatment response than Group A (48.4% <I>vs</I> 21.9%, <I>P</I>=0.027). The resectability of hepatic lesion was higher in Group B (35.5% <I>vs</I> 12.5%, <I>P</I>=0.032). Mean duration from chemotherapy onset to the time of liver resection was 11 cycles (range 4–12) in Group A and 8 cycles (range 8–16) in Group B.</P><P><B>Conclusion:</B></P><P>This study showed that tailored-chemotherapy based on ATP-CRA could improve the treatment response and resectability in initially unresectable colorectal liver metastasis.</P>

<P>To assess the roles of sulfur (S) nutrition in salt stress tolerance in Kentucky bluegrass (Poa pratensis L.). The plants grown in S-supplied or S-deprived condition for 4 weeks were exposed to salt stress with 100 mM NaCl or non-salt stress, respectively, for 21 days. Osmotic potential was significantly decreased by salt stress from day 14. Photosynthetic pigments such as chlorophyll and carotenoid were decreased by salt stress which was more severe in the absence of S, but their content was largely recovered in the presence of S-nutrition. The proteomic analysis of multi-protein complexes in the thylakoid by BN-PAGE showed that the expression of PSI, PSII and RuBisCo level was repressed under salt stress in the absence of S, whereas their expression was largely recovered by S supply. Enzymatic activity confirmed the responses of RuBisCo, estimated by the BN-PAGE, showing a decreased activity in S-deprived and/or salt stressed levels. The decreased RuBisCo activity was significantly related to S content as affected by S nutrition and/or salt stress. Significant relationship between S content and Na, K, Fe content was also observed. These results indicate that S-nutrition modulates the negative responses to salt stress tolerance in photosynthetic organelles of P. pratensis.</P>

<P><B>Background:</B></P><P>Stathmin1 is a microtubule-regulating protein that has an important role in the assembly and disassembly of the mitotic spindle. The roles of stathmin1 in carcinogenesis of various cancers, including prostate and breast cancer, have been explored. However, its expression and roles in gastric cancer have not yet been described.</P><P><B>Methods:</B></P><P>Stathmin1 expression in paraffin-embedded tissue sections from 226 patients was analysed by immunohistochemistry. Roles of stathmin1 were studied using a specific small interfering RNA (siRNA).</P><P><B>Results:</B></P><P>The expression of stathmin1 was positively correlated with lymph node metastasis, TNM stages and vascular invasion, and negatively with recurrence-free survival, in the diffuse type of gastric cancer. The median recurrence-free survival in patients with a negative and positive expression of stathmin1 was 17.0 and 7.0 months, respectively (<I>P</I>=0.009). When the expression of stathmin1 was knocked down using siRNA, the proliferation, migration and invasion of poorly differentiated gastric cancer cells <I>in vitro</I> were significantly inhibited. Moreover, s<I>tathmin1</I> siRNA transfection significantly slowed the growth of xenografts in nude mice.</P><P><B>Conclusion:</B></P><P>These results suggest that stathmin1 can be a good prognostic factor for recurrence-free survival rate and is a therapeutic target in diffuse-type gastric cancer.</P>

<P>We report the identification of novel highly pathogenic avian influenza viruses of subtype H5N6, Glade 23.4.4, that presumably originated from China. In addition, reassortant strains with Eurasian lineage low pathogenic avian influenza viruses were isolated in wild birds and poultry in South Korea. The emergence of these novel H5N6 viruses and their circulation among bird populations are of great concern because of the potential for virus dissemination with intercontinental wild bird migration.
