Abstract
The optimal dose of cisplatin (CDDP) for combination chemotherapy for the treatment of inoperable, advanced gastric cancer has yet to be established. We therefore performed a randomized study to compare the therapeutic usefulness of two dose levels of cisplatin. 5'-deoxy-5-fluorouridine (5'-DFUR 1,400 mg/m(2)/d) was given orally on days 1 to 4 and 15 to 18. Mitomycin C (MMC, 5.75 mg/m(2)/d) was injected intravenously on day 5. In addition, 80 mg/m2/d of CDDP (regimen A) or 60 mg/m(2)/d of CDDP (regimen B) was given by 2-h intravenous drip infusion on day 5. This treatment cycle was repeated every four weeks. Fifty-six patients were enrolled. Clinical response was evaluated in 32 patients (regimen A, 16 patients; regimen B? 16 patients) with measurable lesions. The response rate was significantly higher with regimen A (9 PR/16, 56.3%) than with regimen B (3 PR/16, 18.9%) (p=0.028, chi(2) test). Median survival was slightly but not significantly longer with regimen A (7.4 months) than with regimen B (6.3 months). Drug toxicity included myelosuppression and gastrointestinal symptoms, but there were no serious adverse reactions or differences in safety between the treatment regimens. Regimen A was associated with a high response rate and low toxicity. The optimal dose of CDDP in combination with 5'-DFUR and MMC for the treatment of advanced gastric cancer is regarded to be 80 mg/m(2).

Abstract
The present study examined long-term efficacy outcomes in a subgroup of postmenopausal, estrogen receptor-positive Japanese breast cancer patients from the Pre-Operative "Arimidex" Compared with Tamoxifen trial, following pre-operative (3 months) and post-operative (5 years) adjuvant treatment with either anastrozole or tamoxifen. Patients with large, potentially operable, locally-advanced breast cancer were randomized to receive anastrozole (1 mg/day) plus tamoxifen placebo or tamoxifen (20 mg/day) plus anastrozole placebo pre-operatively. After surgery at 3 months, patients continued on the same study medication as adjuvant therapy for up to 5 years or until recurrence, intolerable toxicity or withdrawal of patient consent. Recurrence-free survival and overall survival were measured from the date of randomization to the date of recurrence or death, whichever occurred first. Patients were monitored for adverse events throughout the study period and up to 30 days following administration of the last study medication. During post-operative adjuvant therapy, 4/48 (8%) anastrozole and 25/49 (51%) tamoxifen patients experienced recurrence. There was a significant difference in recurrence-free survival between the two groups (hazard ratio 0.14; 95% confidence interval 0.05-0.41; P = 0.0003). There was a significant increase in overall survival with anastrozole (0.21; 0.05-0.96; P = 0.0436) and there were 2/48 (4%) and 10/49 (20%) deaths with anastrozole and tamoxifen, respectively. Most patients responding to pre-operative therapy remained recurrence-free. Sequential pre-operative/post-operative treatment with anastrozole resulted in lower recurrence and death rates, compared with tamoxifen.

Abstract
Porcine embryonic fibroblasts (PEFs) are widely used as donor cells for somatic cell nuclear transfer (SCNT) in pigs. Transfection of PEFs with exogenous DNA is essential for producing genetically modified (GM; transgenic or knockout) pigs via SCNT. In this case, selectable markers are strictly required selecting and enriching stably transfected cells. The most frequently used selective drug for this purpose is a neomycin analogue (G418/geneticin); neo has been widely used as a selectable marker gene in the genomic manipulation of pigs. However, little is known about optimal concentrations of other selection drugs. This often hampers functional analysis of the porcine genome and development of individual GM pigs. This study explores the optimal concentrations of selective drugs, other than neomycin, that can be used for the selection of transfected PEFs. Porcine embryonic fibroblasts were incubated in media containing different concentrations of drugs for up to 10 days, to determine the optimal drug concentrations fatal for PEFs. The following concentrations were found to be optimal selective concentrations for use with PEFs: G418/geneticin, 400 μg/ml; blasticidin S, 8 μg/ml; hygromycin B, 40 μg/ml; puromycin, 2 μg/ml; and zeocin, 800 μg/ml. Repeated transfections with plasmids carrying selectable markers resulted in the generation of multidrug-resistant swine transfectants. Furthermore, these markers were found to be independent. The present information will be useful for the production of SCNT-mediated GM piglets that express multiple transgenes.

Abstract
The present study was carried out to compare the gene expression profiles in oocytes derived from adult and prepubertal Japanese Black cattle during in vitro maturation (IVM) using microarray gene chips (Bovine genome array containing 24,072 probe sets representing over 23,000 transcripts). Microarray experiments were conducted using total RNA isolated from immature [germinal vesicle (GV)] and in vitro matured [metaphase II, (MII)] oocytes derived from adult and prepubertal animals. A total of 333 (1.4%) and 549 (2.3%) genes were differentially expressed between prepubertal vs adult bovine GV and MII stages oocytes, respectively. Of these, 176 and 312 genes were up-regulated, while 157 and 237 were down-regulated in prepubertal when compared with adult GV and MII oocytes, respectively. It was also observed that 695 (2.9%) and 553 (2.3%) genes were differentially expressed between GV vs MII stage oocytes in the adult and prepubertal groups, respectively. Gene ontological classification of the differentially expressed genes revealed that up-regulated genes in adult oocytes were involved in signal transduction, transcriptional control and transport. Quantitative reverse transcription-PCR validated the expression profile of some selected transcripts and confirmed differences in the expression levels of transcripts between adult vs prepubertal groups in both GV and MII stages oocytes as identified by microarray data analysis. This study indicated for the first time that significant number of genes were differentially expressed (>2-fold, p < 0.01) between oocytes derived from adult and those from prepubertal Japanese Black cattle, and this difference increased during IVM.

Abstract
AbstractWe have designed and constructed a large area ion beam apparatus to deposit DLC films onto 1000 cm2 surfaces with various geometries. The use of an efficient RF excited ion gun (13.56 MHz, 1 kW power, 50-3000 eV ion energy) with a diameter of 20 cm, enables us to generate various hydrocarbon ions with high ion beam currents, varying ionic species and less maintenance. The use of a four axis (Χ-ϒ-Θϒ-ΘZ) substrate scanner with computer control can produce uniform DLC films on large areas and curved surfaces. The effects of RF power, ion energy, gaseous composition, and total pressure on the properties of DLC have been systematically investigated.

Abstract
ABSTRACTA quadrupole mass spectrometer and a total ion-current measuring device have been utilized to monitor the ion compositions of gas mixtures of CH4/H2 and CH4/H2/O2 during the deposition for quality control and process optimization. An ultra high vacuum system using a 20 cm diameter RF excited (13.56 MIfz) ion gun and a four-axis substrate scanner has been developed for deposition of diamond-like carbon films for electrical, optical, and tribological applications. At a constant RF power of 179W, the mass spectra of gas mixture CH4/H2 (1:2.5) showed the most abundant ion is CH3+. Addition of O2 to the ion source has been found to affect the adhesion, deposition rate, and physical and chemical properties of the DLC films. By use of a mass spectrometer with and without the electron beam, the degree of ionization of CH4 was calculated to be about 10%. As the concentration of O2 was increased, all hydrocarbon ions decreased and H3O+ increased, resulting in a decrease in the film growth rate and an increase in etching of Si and glass substrates. In general, the optical bandgap, adsorption coefficients and refractive index decreased as oxygen concentration increased. Raman spectra showed the G-peak position shifted toward the graphitic peak with narrow peak width as oxygen concentration increased. At ultra high vacuum, the coefficient of friction increased with increased adhesion on substrates as oxygen was increased.

Abstract
Osteopontin (OPN) has recently emerged as a key factor in both vascular remodelling and development of atherosclerosis. It has been reported that OPN is regulated by the renin-angiotensin-aldosterone system (RAAS). The aim of this study was to clarify the effect of angiotensin II receptor blockade with valsartan on plasma OPN levels in patients with essential hypertension (EHT). Forty-six patients (mean age, 64±11 years) with EHT were randomly assigned to treatment with amlodipine or valsartan. There were no significant differences in baseline clinical characteristics between the two groups. Blood sampling and blood pressure evaluation were performed before and after 24 weeks of treatment. After 24 weeks, both systolic blood pressure (SBP) and diastolic blood pressure (DBP) were decreased significantly and by the same degree in each treatment group. However, valsartan but not amlodipine decreased plasma OPN levels (baseline and 24-week data-valsartan: 614±224 ng ml(-1), 472±268 ng ml(-1), P=0.006; amlodipine: 680±151 ng ml(-1), 687±234 ng ml(-1), P>0.999). A positive correlation between the reduction in OPN and the log natural (ln) C-reactive protein (CRP) was seen in the valsartan-treated group. Stepwise regression analysis showed that treatment with valsartan and the reduction of ln CRP were associated with the reduction in OPN levels, and this association was independent of the reduction in SBP or aldosterone levels (valsartan: β=0.332, P=0.026; ln CRP reduction: β=0.366, P=0.015). These results suggest that suppression of the RAAS and inflammation may decrease plasma OPN levels.

Abstract
Human metmyoglobin was separated electrophoretically into four subfractions: Mb(1), Mb(2), Mb(3), and Mb(4), which divide into at least two biochemically independent groups: Mb(1) and Mb(2), and Mb(3), and Mb(4). In normal subjects, Mb(1) constituted the predominant component; Mb(2), Mb(3), and Mb(4) were the minor components in this descending order. In the Duchenne type of progressive muscular dystrophy, on the contrary, a remarkable decrease in Mb(1) and a concomitant increase in Mb(3) were observed. This unique abnormality in the relative distribution of myoglobin subfractions was recognized only in the Duchenne type and not in other types of progressive muscular dystrophy or in other myopathies.

Abstract
BACKGROUND Mutations in TRPV4, a gene that encodes a Ca(2+) permeable non-selective cation channel, have recently been found in a spectrum of skeletal dysplasias that includes brachyolmia, spondylometaphyseal dysplasia, Kozlowski type (SMDK) and metatropic dysplasia (MD). Only a total of seven missense mutations were detected, however. The full spectrum of TRPV4 mutations and their phenotypes remained unclear. OBJECTIVES AND METHODS To examine TRPV4 mutation spectrum and phenotype-genotype association, we searched for TRPV4 mutations by PCR-direct sequencing from genomic DNA in 22 MD and 20 SMDK probands. RESULTS TRPV4 mutations were found in all but one MD subject. In total, 19 different heterozygous mutations were identified in 41 subjects; two were recurrent and 17 were novel. In MD, a recurrent P799L mutation was identified in nine subjects, as well as 10 novel mutations including F471del, the first deletion mutation of TRPV4. In SMDK, a recurrent R594H mutation was identified in 12 subjects and seven novel mutations. An association between the position of mutations and the disease phenotype was also observed. Thus, P799 in exon 15 is a hot codon for MD mutations, as four different amino acid substitutions have been observed at this codon; while R594 in exon 11 is a hotspot for SMDK mutations. CONCLUSION The TRPV4 mutation spectrum in MD and SMDK, which showed genotype-phenotype correlation and potential functional significance of mutations that are non-randomly distributed over the gene, was presented in this study. The results would help diagnostic laboratories establish efficient screening strategies for genetic diagnosis of the TRPV4 dysplasia family diseases.

Abstract
A 25-year-old man with RS rectal cancer received a radical resection of the original tumor and lymph node dissection. Oral tegafur/uracil (UFT)/Leucovorin (LV) therapy has been used for adjuvant chemotherapy, as the pathological Stage was T3N1M0, Stage IIIa. After 10 months from operation, multiple liver metastases were recognized and not resectable. So a systemic chemotherapy by mFOLFOX6+bevacizumab was begun via CV port. After 5 courses of mFOLFOX6+bevacizumab, abdominal CT revealed liver metastases showed remarkable reduction in size. Hepatic resection of S6 segment was enforced, and the patient uneventfully discharged. Pathological findings of S6 segment revealed no residual cancer cells, indicating the histological effect of mFOLFOX6+bevacizumab was Grade 3. And no liver damage was recognized.

Abstract
BACKGROUND Transient receptor potential (TRP)A1, a member of the TRP family of ion channels, has been proposed to function in diverse sensory processes, including thermosensation and pain. However, TRPA1 has not been directly implicated in stomach mechanosensation, and its contribution to acute visceral pain from this organ is unknown. Here, we investigated the expression of TRPA1 in primary sensory afferents and its involvement in visceral hypersensitivity in rats. METHODS We examined TRPA1 expression in the dorsal root ganglion (DRG), nodose ganglion (NG), and stomach of rats by using immunohistochemistry. Electromyographic responses to gastric distention (GD) were recorded from the acromiotrapezius muscle in TRPA1 knockdown rats and in control rats. RESULTS TRPA1 was predominantly expressed with sensory neuropeptides in DRG and NG neurons, and in nerve fibres in the rat stomach. Gastric distention induced the activation of extracellular signal-regulated protein kinase 1/2 (ERK1/2) in DRG and NG neurons 2 min after stimulation, and most of the phosphorylated-ERK1/2-labelled DRG neurons were TRPA1-positive neurons. Intrathecal injection of TRPA1 antisense attenuated the visceromotor response, and suppressed ERK1/2 activation in the DRG, but not NG, neurons produced by GD. Furthermore, intrathecal and intraperitoneal injections of the TRPA1 inhibitor HC-03003 suppressed the response to noxious GD. CONCLUSIONS The activation of TRPA1 in DRG neurons by noxious GD may be involved in acute visceral pain. Our findings point to the potential blockade of TRPA1 in primary afferents as a new therapeutic target for the reduction of visceral hypersensitivity.

Abstract
Primary chylopericardium is an uncommon entity, and its association with pulmonary lymphedema has been rarely reported.We describe a case of primary chylopericardium with pulmonary lymphedema developing into hypoxemia. The pulmonary lesions were histologically diagnosed as pulmonary lymphangiectasis and lymphedema on lung biopsies. Lymphedema seems to suggest the existence of chylous reflux with pulmonary lymphangiectasis. The patient underwent pericardial fenestration and resection of the thoracic duct. After the operation, the chylous accumulation in the pericardial cavity had disappeared,and hypoxemia improved following the disappearance of the pulmonary lesions.

Abstract
Disrupted-in-schizophrenia 1 (DISC1) is a gene disrupted by a (1;11) (q42.1;q14.3) translocation that segregates with major psychiatric disorders in a Scottish family. To investigate how DISC1 confers susceptibility to psychiatric disorders, we previously identified fasciculation and elongation protein zeta-1 and Kendrin as DISC1-interacting molecules in a yeast two-hybrid screen of a human brain complementary DNA library. Here, we have further identified a novel DISC1-interacting protein, termed DISC1-Binding Zinc-finger protein (DBZ), which has a predicted C(2)H(2)-type zinc-finger motif and coiled-coil domains. DBZ was co-immunoprecipitated with DISC1 in lysates of PC12 cells and rat brain tissue. The domain of DISC1 interacting with DBZ was close to the translocation breakpoint in the DISC1 gene. DBZ messenger RNA (mRNA) was expressed in human brains, but not in peripheral tissues. In situ hybridization revealed high expression of DBZ mRNA in the hippocampus, olfactory tubercle, cerebral cortex and striatum in rats. Because this pattern of localization was similar to that of the pituitary adenylate cyclase (PAC(1)) receptor for pituitary adenylate cyclase-activating polypeptide (PACAP), which has recently been implicated in neuropsychological functions, we examined whether DISC1/DBZ interaction was involved in the PACAP signaling pathway. PACAP upregulated DISC1 expression and markedly reduced the association between DISC1 and DBZ in PC12 cells. A DISC1-binding domain of DBZ reduced the neurite length in PC12 cells after PACAP stimulation and in primary cultured hippocampal neurons. The present results provide some new molecular insights into the mechanisms of neuronal development and neuropsychiatric disorders.

Abstract
Chronic ethanol consumption produces a painful peripheral neuropathy. The aim of this study was then to investigate the mechanism underlying the neuropathic pain-like state induced by chronic ethanol treatment in rats. Mechanical hyperalgesia was clearly observed during ethanol consumption and even after ethanol withdrawal, and it lasted for, at least, 14 weeks. At 24 days after ethanol withdrawal, antinociception of morphine was significantly suppressed and the increased guanosine-5'-o-(3-thio) triphosphate ([(35)S]GTPgammaS) binding to membranes of the spinal cord induced by the selective mu-opioid receptor (MOR) agonist, [D-Ala(2),N-MePhe(4),Gly(5)-ol]enkephalin (DAMGO), was significantly decreased under the ethanol-dependent neuropathic pain-like state, whereas the increased [(35)S]GTPgammaS binding to membranes of the spinal cord induced by either the selective delta-opioid receptor (DOR) agonist or kappa-opioid receptor (KOR) agonist was not changed under the ethanol-dependent neuropathic pain-like state. Furthermore, total-MOR immunoreactivity was not changed in the spinal cord of ethanol-fed rats. Under these conditions, immunoblotting showed a robust increase in phosphorylated-cPKC immunoreactivity (p-cPKC-IR) in the spinal cord from chronic ethanol fed-rats, whereas phosphorylated-protein kinase A (PKA), dynamin II and G protein-coupled receptor kinase 2 (GRK2) were not affected in the spinal cord of ethanol-fed rats. These findings suggest that the dysfunction of MOR, but not DOR and KOR, linked to cPKC activation in the spinal cord may be, at least in part, involved in the reduced sensitivity to antinociception induced by morphine under the ethanol-dependent neuropathic pain-like state.
