Abstract
The pigment cell-specific gene, located at the brown (b)-locus in mouse, encodes the protein that determines the type of melanin synthesized. This protein is known as tyrosinase-related protein, but here we tentatively term it b-locus protein to avoid confusions with the related sequence cross-hybridizing to the tyrosinase gene. In order to identify the mutation at the b-locus, we have cloned and characterized the b-locus protein gene of BALB/c mouse (b/b, c/c). The gene is about 18 kb long and organized into 8 exons and 7 introns. Sequence analysis of the b-locus protein gene reveals four base changes within the protein-coding regions: two missense mutations and two silent mutations. Two missense mutations result in the Cys to Tyr substitution at position 86 (codon 110) and the Arg to His substitution at position 302 (codon 326) of a b-locus protein molecule. Using allele-specific amplification, we confirmed that these missense mutations are actually present in the genomic DNA of two b-mutant strains examined, BALB/c and DBA/2 (b/b, C/C) mice, suggesting that these mutations are specific for the mutant mice at the b-locus. Moreover, we are able to show that the b-locus protein containing Tyr 86 is not reactive with the anti-b-locus protein monoclonal antibody, TMH-1, in transient expression assays.

Abstract
In the past several decades, the tropospheric westerly winds in the Southern Hemisphere have been observed to accelerate on the poleward side of the surface wind maximum. This has been attributed to the combined anthropogenic effects of increasing greenhouse gases and decreasing stratospheric ozone and is predicted to continue by the Intergovernmental Panel on Climate Change/Fourth Assessment Report (IPCC/AR4) models. In this paper, the predictions of the Chemistry-Climate Model Validation (CCMVal) models are examined: Unlike the AR4 models, the CCMVal models have a fully interactive stratospheric chemistry. Owing to the expected disappearance of the ozone hole in the first half of the 21st century, the CCMVal models predict that the tropospheric westerlies in Southern Hemisphere summer will be decelerated, on the poleward side, in contrast with the prediction of most IPCC/AR4 models.

Abstract
AIMS To determine the chromosomal location and entire sequence of Lg-FLO1, the expression of which causes the flocculation of bottom-fermenting yeast. METHODS AND RESULTS Two cosmid clones carrying DNA from a bottom-fermenting yeast chromosome VIII right-arm end were selected by colony hybridization. Sequencing revealed that the clones contained DNA derived from a Saccharomyces cerevisiae type chromosome VIII and a Saccharomyces bayanus type chromosome VIII, both from bottom-fermenting yeast. CONCLUSIONS Lg-FLO1 is located on the S. cerevisiae type chromosome VIII at the same position as the FLO5 gene of the laboratory yeast S. cerevisiae S288c. The unique chromosome VIII structure of bottom-fermenting yeast is conserved among other related strains. FLO5 and Lg-FLO1 promoter sequences are identical except for the presence of three 42 bp repeats in the latter, which are associated with gene activity. Flocculin genes might have been generated by chromosomal recombination at these repeats. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first report of the exact chromosomal location and entire sequence of Lg-FLO1. This information will be useful in the brewing industry for the identification of normal bottom-fermenting yeast. Moreover, variations in the FLO5 locus among strains are thought to reflect yeast evolution.

Abstract
We investigated the possible influence of an exhaustive physical exercise on mental stress biomarkers (serotonin, tryptophan, and beta-endorphin) along with dopamine, noradrenaline and free fatty acids in an ultramarathon race in which 45 km was run on the first day and 90 km on the second. We obtained serum samples at 6 different time points during and after the race from 18 Japanese male runners who completed the marathon. Overall changes of serum serotonin and tryptophan concentrations were statistically significant according to ANOVA for repeated measurements (p < 0.05). Serum serotonin levels elevated rapidly on the first day with the post hoc Tukey's test. Tryptophan concentrations inversely decreased during the race, possibly because of utilization for synthesis of serotonin. Levels of beta-endorphin appeared to increase on the first and second days, but were not statistically significant. In conclusion, serum serotonin, tryptophan and beta-endorphin appeared to be used for mental stress markers in physical exercise.

Abstract
AIMS Hepatic resection is the most effective therapy for hepatocellular carcinoma (HCC); however, intrahepatic recurrence is common. Predictors of survival after intrahepatic recurrence have not been fully investigated. To clarify the prognosis and choice of treatment of intrahepatic recurrence after hepatic resection, we conducted a comparative retrospective analysis of 147 patients with HCC who underwent hepatic resection. METHODS We retrospectively examined the relations between clinicopathologic factors, including the number of recurrent intrahepatic tumors and long-term prognosis after recurrence in 147 HCC patients who underwent resection. We also examined long-term survival after recurrence based on treatment types and recurrence pattern. RESULTS Patients with multiple tumors (n=83) showed less tumor differentiation, more frequent portal invasion, a higher alpha-fetoprotein level, and larger tumors than did patients with solitary tumor (n=64). In the solitary tumor group, local ablation therapy and repeat hepatic resection were performed in 25 and 10, respectively. In the multiple tumor group, 59 were treated by transarterial chemoembolization. Multivariate analysis showed intraoperative blood transfusion and multiple tumors to be independent risk factors for poor cancer-related survival after recurrence. By subset analysis based on treatment types and recurrence pattern, survival after recurrence was significantly better in patients treated by local ablation therapy than those treated by other therapies in both solitary and multiple tumor groups. CONCLUSIONS For patients with solitary recurrence, a good prognosis is predicted. Local ablation therapy is a best candidate for treatment of solitary and multiple intrahepatic recurrences after hepatic resection.

Abstract
The purpose of this study was to evaluate the efficacy of gefitinib and the feasibility of screening for epidermal growth factor receptor (EGFR) mutations among select patients with advanced non-small cell lung cancer (NSCLC). Stage IIIB/IV NSCLC, chemotherapy-naive patients or patients with recurrences after up to two prior chemotherapy regimens were eligible. Direct sequencing using DNA from tumour specimens was performed by a central laboratory to detect EGFR mutations. Patients harbouring EGFR mutations received gefitinib. The primary study objective was response; the secondary objectives were toxicity, overall survival (OS), progression-free survival (PFS), 1-year survival (1Y-S) and the disease control rate (DCR). Between March 2005 and January 2006, 118 patients were recruited from 15 institutions and were screened for EGFR mutations, which were detected in 32 patients – 28 of whom were enrolled in the present study. The overall response rate was 75%, the DCR was 96% and the median PFS was 11.5 months. The median OS has not yet been reached, and the 1Y-S was 79%. Thus, gefitinib chemotherapy in patients with advanced NSCLC harbouring EGFR mutations was highly effective. This trial documents the feasibility of performing a multicentre phase II study using a central typing laboratory, demonstrating the benefit to patients of selecting gefitinib treatment based on their EGFR mutation status.

Abstract
Using the urinary 8-hydroxydeoxyguanosine (8-OHdG) concentration, effects of participation in a two-day ultramarathon race period on oxidative DNA damage were investigated in Japanese nonprofessional runners. Before the first day (baseline), after the first day (mid-race) of 40-km running, and after the second day (post-race) of 90 km running, biomaterials were successfully sampled from 95 participants (males, 79; females, 16) who completed the full race. We analyzed urine for 8-OHdG and blood for aspartate aminotransferase (AST), creatine phosphokinase (CPK) and myoglobin, and evaluated fluctuation in the values at three sampling time points. Adjusted baseline urinary 8-OHdG levels (microg/g creatinine) (mean +/- standard deviation) showed no significant differences between males and females, at 2.85 +/- 1.17 and 3.04 +/- 1.56, respectively. In males, mid-race urinary 8-OHdG levels rose to 3.29 +/- 1.15 (p < 0.01), but then returned to 2.73 +/- 1.16 at the post-race time point (p < 0.01). In females, a similar increase to 3.32 +/- 1.47 and subsequent decline to 2.80 +/- 1.47 were noted. In contrast, AST, CPK and myoglobin were increased at both mid- and post-time points and particularly the latter, independent of the sex. Extreme prolonged exercise in a two-day ultramarathon race period causes oxidative DNA damage but antioxidant repair systems are apparently induced to protect against oxidative DNA stress with physical exercise.

Abstract
A 52-year-old male presented with right sudden deafness and left isolated limb sensory disturbance following posterior neck pain. An examination revealed a mild degree of right sensory neural hearing loss and decreased pain and thermal sensation in the left side below the L3 level. Brain MRI showed a small lesion in the midlateral portion of the right middle-rostral medulla. The combination of the image findings suggests a right lateral medullary infarction caused by a vertebral artery (VA) dissection. In our case, the fibers carrying the modalities of the lateral spinothalamic tract restricted to below the L3 level, sparing other sensations, suggest a selective involvement. This finding suggests that sensory dermatomal representation in the modality may be preserved at least up to the level of the medulla oblongata. Moreover, in our case, the small emboli originating from the dissected VA possibly caused a small selective cochlear infarction. This type of embolism may give rise to various combinations of symptoms depending on the branches involved. For patients with an acute onset of headache or neck pain who present with isolated limb sensory disturbance accompanied by sudden deafness, even without the classical brainstem signs, a VA dissection and medullary infarction should therefore be considered.

Abstract
The crystal structures, thin-film properties, and field-effect transistor (FET) characteristics of tetrathiafulvalene (TTF) derivatives with two phenyl groups are systematically investigated. The highest mobility, 0.11 cm(2) V(-1) s(-1), is observed in biphenyl-substituted TTF (1). The correlation between the crystal structures and the FET properties demonstrates that good transistor properties are associated with two-dimensional intermolecular interaction, which is achieved when the molecules are standing nearly perpendicular to the substrate. Since these TTF derivatives are strong electron donors, the use of a metallic charge-transfer salt (TTF)(TCNQ) as the source and drain electrodes has resulted in a considerable reduction of the off current (TCNQ: tetracyanoquinodimethane).

Abstract
We study competition between the Kondo effect and superconductivity in a single self-assembled InAs quantum dot contacted with Al lateral electrodes. Because of Kondo enhancement of Andreev reflections, the zero-bias anomaly develops side peaks, separated by the superconducting gap energy Delta. For ten valleys of different Kondo temperature T(K) we tune the gap Delta with an external magnetic field. We find that the zero-bias conductance in each case collapses onto a single curve with Delta/k(B)T(K) as the only relevant energy scale, providing experimental evidence for universal scaling in this system.

Abstract
Listeria monocytogenes induces apoptosis in vitro and in vivo in a variety of cell types. However, the mechanism of cell death in L. monocytogenes-infected macrophages was initially reported to be distinct from apoptosis. Here, we studied the mechanism of L. monocytogenes-induced cell death using sensitive fluorescent techniques. We found that caspase-1 activation preceded cell death of macrophages infected with L. monocytogenes, using fluorogenic substrates. Caspase-1 activation was diminished after infection with wild-type L. monocytogenes when cells were treated with NH(4)Cl, or if they were infected with a listeriolysin mutant that cannot escape from the phagolysosome. Mitochondrial membrane integrity was preserved during the infection. A particular mechanism of cell death, recently termed 'pyroptosis', is associated with infection by intracellular microorganisms, and has an inherent pro-inflammatory character, due to involvement of caspase-1 activation with consequent IL-1 beta and IL-18 production. Cell death through caspase-1 activation would constitute a defence mechanism of macrophages which induces cell death to eliminate the bacteria's intracytosolic niche and recruits early host's defences through the secretion of inflammatory cytokines.

Abstract
The number of tumor-infiltrating lymphocytes is known to be related to outcomes in patients with a variety of malignancies. Interferon (IFN) gamma-inducible protein-10 (IP-10) and monokine induced by IFNgamma (MIG) have chemotactic effects on activated T lymphocytes and natural killer (NK) cells. The aim of this study was to evaluate the antitumor effects of exogenous expression of the MIG and IP-10 genes delivered to solid tumors by poly [D,L-2,4-diaminobutyric acid] (PDBA). The murine MIG and IP-10 genes were transfected into mouse neuroblastoma cells with PDBA. MIG and IP-10 levels in supernatants of transfected cells were measured by enzyme-linked immunosorbent assay. The chemotactic activities of MIG and IP-10 in the supernatants of cell cultures were measured by chemotaxis assay. Tumors were injected in vivo with PDBA/pmMIGColon, two colonsIP-10 complexes to evaluate the effects of these genes on tumor volume and survival time of mice. Transfected PDBA/pmMIGColon, two colonsIP-10 complexes produced MIG and IP-10 protein in vitro. MIG and IP-10 proteins secreted into the culture medium showed chemotactic activity. MIG and IP-10 gene therapy with the PDBA system in vivo significantly inhibited tumor growth and prolonged survival time of mice. In conclusion, PDBA-mediated MIG and IP-10 gene therapy may be useful for treatment of solid tumors.

Abstract
AIMS The effect of perioperative blood transfusion on the survival of hepatocellular carcinoma (HCC) has not been fully investigated. To clarify the prognostic value of intraoperative allogenic blood transfusion, we conducted a comparative retrospective analysis of 224 patients with HCC who underwent hepatic resection. METHODS We compared clinicopathologic background and survival after hepatic resection between patients who received intraoperative blood transfusion (n=101) and those who did not (n=123). RESULTS Patients with blood transfusion had a larger tumor and more frequent vascular invasion than those without blood transfusion. The 5-year cancer-related survival rate after hepatic resection, but not the disease-free survival rate, was significantly lower in patients who underwent blood transfusion than in those who did not (38.3% vs. 66.7%, P<0.01). Multivariate analysis showed intraoperative blood transfusion (P=0.02), microscopic portal invasion (P<0.01), and preoperative serum alpha-fetoprotein elevation (P=0.03) to be independent risk factors for poor outcome after hepatic resection. The negative effect of blood transfusion on postoperative survival was observed only in patients with a tumor larger than 50mm in diameter. The absolute peripheral blood lymphocyte count on postoperative day 1 was significantly lower in patients who underwent blood transfusion (880/mm(3)) than in those who did not (1081/mm(3)) (P<0.01). CONCLUSIONS Our data suggest that intraoperative blood transfusion results in immunosuppression in the early postoperative period, allowing for progression of residual HCC after resection. Therefore, intraoperative allogenic blood transfusion should be avoided in patients with resectable HCC, particularly in those with a large tumor.

Abstract
The photochemical behavior of the antifouling agent zinc pyrithione (ZnPT) was studied in aqueous media of different composition under simulated solar irradiation using a xenon light source. The influence of important constituents of natural water (dissolved organic matter and nitrate) was also examined using a multivariate kinetic model. It was found that photodegradation proceeds via a pseudo first-order reaction. Kinetic experiments were monitored by LC-MS and photolytic half-lives ranging between 9.2 and 15.1 min have been observed. The increasing concentration of dissolved organic matter (DOM) accelerates the photolysis reaction, while the effect of nitrate ions was also positive since it increased the degradation rate, but to a lesser extent. Irradiation of the aqueous ZnPT solutions gave rise to several transformation products that were isolated by means of solid-phase extraction using poly(styrene-divinylbenzene) extraction disks. These byproducts were identified using liquid chromatography-atmospheric pressure chemical ionisation mass spectrometry. Besides 2-pyridinesulfonic-acid, other degradation products formed included pyridine-N-oxide, 2-mercaptopyridine, 2,2'-dithiobis(pyridine-N-oxide), 2,2-dipyridyl disulfide and the pyridine/pyrithione mixed disulfide, 2,2'-dithiobispyridine mono-N-oxide (PPMD).

Abstract
Twist is a transcription factor that regulates the expression of tumour suppressors such as E-cadherin. We examined the distribution and expression of Twist in human epithelial ovarian carcinoma (EOC) to examine its clinical significance. Paraffin sections from EOC tissues (n=82) were immunostained with Twist antibody, and the staining intensity was evaluated. The clinicopathological factors examined were age, International Federation of Gynecology and Obstetrics staging, histological type, tumour grade, preoperative value of CA125, peritoneal cytology, volume of ascites and residual tumour after cytoreductive surgery. Overall survival (OS) and progression-free survival (PFS) were evaluated using the Kaplan-Meier method, and multivariate analysis was performed using the Cox proportional hazard analysis. Of the 82 carcinomas, 49 (59.8%) cases were negative for Twist immunoexpression, and 33 (40.2%) were positive immunoexpression. When categorized into negative vs positive expression, Twist was not associated with any of the clinicopathological parameters examined. However, positive Twist expression significantly predicted poorer OS and PFS when compared with negative expression (P<0.0001). In the multivariate analyses, positive Twist expression was the only independent prognostic factor for survival in this study (P<0.0001). Positive Twist expression seems to be a useful marker in patients with EOC likely to have an unfavourable clinical outcome.

Abstract
Indoleamine 2,3-dioxygenase (IDO) is a tryptophan-catabolising enzyme inducing immune tolerance. The present study aimed to investigate IDO expression and its prognostic significance in endometrial cancer. Indoleamine 2,3-dioxygenase expression in endometrial cancer tissues (n = 80) was immunohistochemically scored as four groups (IDO-, 1+, 2+, and 3+). The high IDO expression (IDO2+ or 3+) in tumour cells was found in 37 (46.3%) of the 80 cases, and was positively correlated with surgical stage, myometrial invasion, lymph-vascular space involvement, and lymph node metastasis, but not with the histological grade. Patients with high IDO expression had significantly impaired overall survival and progression-free survival (PFS) (P = 0.002 and P = 0.001, respectively) compared to patients with no or weak expression of IDO (IDO- or 1+). The 5-year PFS for IDO-/1+, 2+, and 3+ were 97.7, 72.9, and 36.4%, respectively. Even in patients with early-stage disease (International Federation of Gynecology and Obstetrics I/II, n = 64), the PFS for IDO2+/3+ was significantly poor (P = 0.001) compared to that for IDO-/1+. On multivariate analysis, IDO expression was an independent prognostic factor for PFS (P = 0.020). These results indicated that the high IDO expression was involved in the progression of endometrial cancer and correlated with the impaired clinical outcome, suggesting that IDO is a novel and reliable prognostic indicator for endometrial cancer.

Abstract
The surface conformational states of the Gibbs monolayer of ethylene glycol mono-n-dodecyl ether (C(12)E(1)) at the air/water interface was studied using dynamic surface tension, external reflection-absorption FT-IR spectroscopy (ERA FT-IR), and two-dimensional infrared (2D IR) correlation methods at constant temperature. The dynamic surface tensions were measured at different bulk concentrations of C(12)E(1), and it was observed that a constant surface tension region appears at approximately 38.5 mN m(-1) in a dynamic surface tension profile at concentrations higher than 11 micromol kg(-1). This constant surface tension region corresponds to the surface phase transition from liquid expanded (LE) to liquid condensed (LC). Two sets of ERA FT-IR spectra were collected, one at different bulk concentrations but after equilibrium time (equilibrium measurements) and another at constant bulk concentration (m = 16 micromol kg(-1)) but at different times (dynamic measurements). The first set of these measurements show that the peak area increases in the range of 11 < m < or = 16 micromol kg(-1), which means the increase in the number of surfactant molecules at the air/water interface. Also, the wavenumber of antisymmetric CH(2) stretching decreases gradually from approximately 2923 cm(-1) (for 10 and 11 micromol kg(-1)) to approximately 2918 cm(-1) (for m > or = 16 micromol kg(-1)) with increasing concentration. The wavenumbers of 2923 and 2918 cm(-1) were assigned to LE and LC phases, respectively, and the decrease of wavenumber in the concentration range of 11 < m < or = 16 micromol kg(-1) were correlated to the surface phase transition (LE --> LC), or in other words, in the mentioned concentration range, two phases coexist. The dynamic ERA FT-IR measurements at 16 micromol kg(-1) also confirm the surface phase transition from LE to LC. The 2D IR correlation method was applied to the both equilibrium and dynamic IR spectra of the C(12)E(1) monolayer. The synchronous correlation maps show two strong autopeaks at approximately 2922 and approximately 2851 cm(-1) and also show a strong correlation (cross-peaks) between antisymmetric CH(2) stretching (nu(a)) and symmetric CH(2) stretching (nu(s)). The asynchronous correlation maps show that both observed bands of nu(a) and nu(s) in one-dimensional IR split into two components with the characteristic of overlapped bands, which reveals the coexistence of two phases (LE and LC) at the interface at 11 < m < or = 16 micromol kg(-1). The synchronous and asynchronous maps that were obtained from dynamic IR spectra closely resembled the equilibrium map.

Abstract
AIMS To study the effect of preoperative transcatheter arterial chemoembolization (TACE) on long-term survival after hepatic resection for hepatocellular carcinoma (HCC), we conducted a comparative analysis in 235 HCC patients who underwent hepatic resection with a curative intent. METHODS We compared clinicopathologic background, mortality, and survival rates after hepatic resection between those who underwent preoperative TACE (n=109) and those who did not (n=126). RESULTS One hundred and two patients in the TACE group (93.6%) received TACE only once. The mean interval between TACE and hepatic resection was 33.1days. Patients in the TACE group were younger than those in the non-TACE group, and liver cirrhosis and non-anatomical hepatic resection were more prevalent in this group. The 5-year overall survival rate after hepatic resection was significantly lower in the TACE group (28.6%) than in the non-TACE group (50.6%), especially in patients without cirrhosis or with stage I or II tumor. There was no difference between the two groups in mortality or disease-free survival after hepatic resection. Multivariate analysis showed preoperative TACE, preoperative aspartate aminotransferase elevation, and microscopic portal invasion to be independent risk factors for a poor outcome after hepatic resection. CONCLUSIONS Preoperative TACE should be avoided for patients with resectable HCC, especially for those without cirrhosis or with an early stage tumor.

Abstract
13030 Background: In non-small cell lung cancer (NSCLC), sensitivity to gefitinib is associated with activating mutations of the epidermal growth factor receptor (EGFR). Tumor samples obtained for diagnosis of NSCLC are limited and often unsuitable for analysis of mutations. Other biomarkers are thus needed. We previously reported that serum vascular endothelial growth factor (VEGF) levels were significantly lower in responders to gefitinib than non-responders. To assess levels of circulating VEGF as a predictive and prognostic marker of gefitinib treatment in NSCLC patients, we examined the associations between plasma VEGF levels before gefitinib treatment and clinical outcome. Methods: Eighty four NSCLC patients treated with gefitinib were enrolled into this investigation. Plasma VEGF levels were measured in blood samples before gefitinib administration. Patients were grouped according to VEGF level around a cut-off of 80.7 pg/ml, based on results from normal controls. Response to gefitinib was judged using RECIST guidelines. Time to progression (TTP) and overall survival (OS) following gefitinib treatment were calculated using Kaplan-Meier methods. Groups were compared using log-rank test. We evaluated the immunohistochemical expression of VEGF and EGFR mutations in tumor samples from 37 patients. Results: Response rate was significantly higher with low VEGF level than with high VEGF level (p = 0.0010). Multivariate analysis for response to gefitinib including sex, histology, smoking status, performance status and plasma VEGF level identified only low VEGF level as predictive of response to gefitinib. Low VEGF level was also correlated with prolonged median TTP (4.1 months vs. 1.1 months, p = 0.0081) and OS (11.1 months vs. 5.4 months, p = 0.0290). Multivariate analysis for survival revealed low VEGF level as associated with prolonged TTP (p = 0.0081) and OS (p = 0.0708). Plasma VEGF level was not associated with either VEGF expression or EGFR mutations of tumor tissue. Conclusions: Our results suggest that plasma VEGF levels before gefitinib treatment are predictive of response to gefitinib and prognostic of patients who receive gefitinib. [Table: see text]

Abstract
7192 Background: Epidermal growth factor receptor (EGFR) gene amplification and mutation have been reported to be predictors of response to EGFR inhibitors. We evaluated EGFR gene copy number and mutations in biopsy samples of non-small cell lung cancer (NSCLC) treated with gefitinib (G) and analyzed the correlation between gene status and clinical outcome. Methods: EGFR gene copy numbers in biopsy samples were evaluated using FISH and categorized as described by Cappuzzo et al. We also performed mutational analysesof exons 18, 19 and 21 of EGFR by PCR and direct sequencing. Response was judged using the RECIST guidelines. Time to progression (TTP) and overall survival (OS) were calculated and evaluated by the Kaplan-Meier method. Groups were compared using the log-rank test. Risk factors associated with survival were evaluated using Cox proportional hazards regression modeling and multivariable analysis. Results: Of 59 patients (pts) enrolled in this investigation, 24 pts (41%) were female and 21 pts (35%) had never smoked. The most common histological subtype was adenocarcinoma (73%) and 36 pts (61%) had good PS 0–1. Gene copy numbers could be analyzed in 54 pts. Gene amplification was observed in 21 pts, high polysomy in 5 pts, low polysomy in 18 pts, low trisomy in 5 pts and disomy in 5 pts. FISH positivity was observed in 26 pts (48%). EGFR mutations were detected in 18 pts (31%); point mutations in exon 21 were observed in 5 pts, in-frame deletions in exon 19 in 12 pts, a point mutation in exon 18 in 1 pt. Response rate in pts with EGFR mutations was significantly higher than in pts without mutations (56% vs. 15%, p = .0011). Response rate in FISH-positive pts was 31% and that in FISH-negative pts was 21%, the association with response was not significant. EGFR mutations were also correlated with improved TTP (median 8.3 m vs. 1.8 m, p = .0014) and OS (median 18.8 m vs. 6.4 m, p = .0059). There were no significant differences in TTP and OS based on FISH positivity. On multivariable analysis, EGFR mutations remained significantly associated with improved TTP and OS. Conclusions: Our results suggest that EGFR mutations are a better predictor of clinical benfit of G when compared with gene copy number in Japanese NSCLC pts. [Table: see text]

Abstract
OBJECTIVES Several studies including ours have suggested that lack of CD56 in multiple myeloma (MM) defines a unique patient subset with poorer prognosis. However, the mechanism underlying this aggressive behavior of CD56(-) MM has not been well elucidated. Interleukin-6 (IL-6) or insulin-like growth factor I (IGF-I) induce proliferation of MM cells. In this study, we report about the relationship between CD56 expression and responsiveness to these cytokines. METHODS We sorted out both CD56(-) and CD56(+) fractions from MM cell lines such as KMS-21-BM and U-266, and investigated their different responsiveness to IL-6 or IGF-I. Furthermore, we compared the effects of these cytokines on the regulation of cell-cycle distribution between CD56(-) and CD56(+) cells. RESULTS Although CD56(-) cells in both KMS-21-BM and U-266 cells responded significantly to IL-6, CD56(+) cells did not. Ki-67(+) cells in the CD56(-) cells were significantly increased by IL-6. Western blotting showed that IL-6 phosphorylated Akt, and upregulated and downregulated the level of cyclin D1 and p27 protein in the CD56(-) KMS-21-BM cells, respectively. LY-294002 completely blocked these effects of IL-6. On the other hand, Ki-67(+) cells in the CD56(+) cells did not respond to IL-6. Anti-IGF-I mAb significantly reduced Ki-67(+) cells only in the CD56(+) cells. IGF-I phosphorylated Akt and upregulated cyclin D1 in the CD56(+) KMS-21-BM cells, which was completely blocked by LY294002. CONCLUSIONS These results suggest that CD56(-) and CD56(+) MM cells could be stimulated by IL-6 and IGF-I, respectively, via PI3-K/Akt pathway, and provide useful information for anticytokine therapies.

Abstract
Angiotensin II, a main effector peptide in the renin–angiotensin system, acts as a growth-promoting and angiogenic factor via type 1 angiotensin II receptors (AT1R). We have recently demonstrated that angiotensin II enhanced tumour cell invasion and vascular endothelial growth factor (VEGF) secretion via AT1R in ovarian cancer cell lines in vitro. The aim of the present study was to determine whether AT1R expression in ovarian cancer is correlated with clinicopathological parameters, angiogenic factors and patient survival. Immunohistochemical staining for AT1R, VEGF, CD34 and proliferating cell nuclear antigen (PCNA) were analysed in ovarian cancer tissues (n=67). Intratumour microvessel density (MVD) was analysed by counting the CD34-positive endothelial cells. Type 1 angiotensin II receptors were expressed in 85% of the cases examined, of which 55% were strongly positive. Type 1 angiotensin II receptors expression was positively correlated with VEGF expression intensity and MVD, but not with histological subtype, grade, FIGO stage or PCNA labelling index. In patients who had positive staining for AT1R, the overall survival and progression-free survival were significantly poor (P=0.041 and 0.017, respectively) as compared to those in patients who had negative staining for AT1R, although VEGF, but not AT1R, was an independent prognostic factor on multivariate analysis. These results demonstrated that AT1R correlated with tumour angiogenesis and poor patient outcome in ovarian cancer, suggesting its clinical potential for a novel molecular target in strategies for ovarian cancer treatment.

Abstract
OBJECTIVES Cyclooxygenase-2 (COX-2) is reported to regulate apoptosis and to be an important cellular target for therapy. METHODS We examined whether etodolac, meloxicam, and thalidomide inhibited proliferation and induced apoptosis in myeloma cell lines (RPMI 8226 and MC/CAR cells). RESULTS Etodolac induced apoptosis more strongly compared with thalidomide or meloxicam. Etodolac induced down-regulation of Bcl-2 protein and mRNA, activation of Caspase-9, -7 and -3, cIAP-1 and Survivin, and loss of mitochondrial membrane potential in a dose-dependent manner. In addition, when myeloma cells were coincubated with 50 microM etodolac on bone marrow stromal cells (BMSCs), myeloma cell adhesion to BMSCs was significantly inhibited compared with thalidomide or meloxicam coincubation, and the adhesion molecules VLA-4, LFA-1 (CD11a), CXCX4, and CD44 were suppressed on myeloma cells treated with etodolac. Moreover, 50-100 microM racemate of etodolac significantly inhibited the proliferation of myeloma cells compared to 100 microM R-etodolac or S-etodolac. CONCLUSIONS Etodolac induced loss of mitochondrial membrane potential and apoptosis via a COX-2-independent pathway, suppressed the expression of adhesion molecules, and inhibited myeloma cell adhesion to BMSCs compared with thalidomide or meloxicam. The activities of etodolac potentially extend to the treatment of patients with myeloma resistant to standard chemotherapy, including thalidomide.

Abstract
BACKGROUND alpha-Fetoprotein (AFP) has been used as a marker for hepatocellular carcinoma (HCC). However, AFP levels are often high in patients with chronic hepatitis or cirrhosis. Protein-induced vitamin K absence or antagonist II (PIVKA-II) is more sensitive for the diagnosis of HCC and prediction of patient survival. Changes in these markers after treatment may reflect treatment curability and patient outcome. METHODS We conducted a retrospective analysis of prognosis of 63 HCC patients with high preoperative levels of AFP and PIVKA-II who underwent hepatectomy and examined the relationship between postoperative changes in both markers at 1 month and patient survival. Subjects were divided into three groups according to changes in these tumour markers after hepatectomy: normalization (N) group, decreased but still above the normal level (D) group and unchanged (U) group. RESULTS There were no significant differences in the numbers of patients who developed tumour recurrence between changes in AFP and PIVKA-II. Survival analysis showed no significant differences in tumour-free and overall survivals between groups with respect to AFP level. The PIVKA-II-N group showed significantly better tumour-free and overall survival compared with the D and U groups (p<0.01). Multivariate analysis that included other prognostic factors identified changes in PIVKA-II level as a significant and independent prognostic factor associated with overall survival. DISCUSSION Although changes in AFP did not correlate with patient prognosis, normalization of PIVKA-II was significantly associated with good patient survival after hepatectomy. Normalization of PIVKA-II after hepatectomy reflected the efficacy of treatment and is a suitable predictor of prognosis in HCC patients.

Abstract
Several cohort studies have examined the association of carotid intima-media thickness (IMT) with the risk of stroke or myocardial infarction in apparently healthy persons. We investigated the predictive value of IMT of cardiovascular mortality in elderly community-dwelling people, beyond the prediction provided by age and MMSE, assessed by means of a multivariate Cox model. Carotid IMT and plaque were evaluated bilaterally with ultrasonography in 298 people older than 75 years (120 men and 178 women, average age: 79.6 years). The LILAC study started on July 25, 2000. Consultations were repeated every year. The follow-up ended on November 30, 2004. During the mean follow-up span of 1152 days, 30 subjects (21 men and nine women) died. Nine deaths were attributable to cardiovascular causes (myocardial infarction: two men and three women; stroke: two men and two women). The age- and MMSE-adjusted relative risk (RR) and 95% confidence interval (95% CI) of developing all-cause mortality was assessed. A 0.3 mm increase in left IMT was associated with a RR of predicted 1.647 (1.075-2.524), and a similar increase in right IMT with a RR of 3.327 (1.429-7.746). For cardiovascular mortality, the corresponding RR values were 2.351 (1.029-5.372) and 2.890 (1.059-7.891), respectively. Carotid IMT assessed by ultrasonography is positively associated with an increased risk of all-cause and cardiovascular death in elderly community-dwelling people.

Abstract
Ophthalmoplegic migraine (OM) is a rare variant of migraine characterized by recurrent attacks of severe headache followed by oculomotor nerve palsy. The recent revision of the International Headache Classification has reclassified OM from a subtype of migraine, defined as a functional headache, to the neuralgia category. We describe a case of an 11-year-old girl with pathologically confirmed oculomotor nerve schwannoma who had been suffering from symptoms mimicking OM. For five years, she has been under treatment for OM, an initial diagnosis which was corroborated by brain magnetic resonance imaging (MRI). Usually, most OM attacks occur during one period in a lifetime and remit completely. In contrast, however, her attacks became more frequent and were not controlled by medication. After surgery, the frequency of OM attacks was reduced. From this experience, we hypothesize that optic nerve tumor is one condition that can mimic OM, without apparent signs suggestive of intracranial mass. To our knowledge, this is the first report to describe a pathologically confirmed case of oculomotor nerve schwannoma mimicking OM.
