Abstract
A new type of U-shape anti-cathode X-ray generator in which the inner surface of a cylindrical target is irradiated by an electron beam has been made by modifying a conventional rotating anti-cathode X-ray generator whose brightness in the catalog is 12 kW mm(-2). The target material (Cu), target radius (50 mm) and rotating speed (6,000 r.p.m.) were not changed in this modification. A brightness of 52 kW mm(-2) was obtained by this U-shape-type X-ray generator. This means that the brightness of the new type is 4.3 times greater than that of the old unmodified one. Furthermore, the new-type X-ray generator yielded a brightness of 129 kW mm(-2) by adding a carbon coating on the Cu target. This means an overall increase of brightness of ten times. The original generator has the highest brightness in the generators of the same class (having a radius of 50 mm and rotation speed of 6,000 r.p.m.). Observations showed that Cu Kα counts at vertical incidence of the electron beam onto the surface of the new target, which is initially optically smooth, decrease as the surface is roughened by a severe thermal stress caused by strong electron beam exposure. Further observation reveals, however, that oblique incidence of the electron beam onto the roughened surface drastically increased the X-ray output and amounts to twice as much as that from a smooth surface at vertical incidence. Thus, at the present stage, an overall increase of brightness has been realised at a level 20 times stronger than that of the original commercially offered X-ray generator that we modified.

Abstract
We experienced two patients with mixed phenotype acute leukemia with t(9;22)(q34;q11.2); BCR-ABL1 according to the WHO classification 2008. The type of BCR/ABL1 was major in both patients, and the chimeric gene was also detected in neutrophils from peripheral blood by the fluorescence in situ hybridization technique. Patient 1 was a 59-year-old Japanese woman, and patient 2 a 45-year-old Japanese man. They had both developed leukemia suddenly. Their leukemic blasts expressed B cell and myeloid cell antigens, but concomitantly in patient 1 (biphenotypic) and separately in patient 2 (biclonal). Percentages of BCR-ABL1-positive neutrophils were 98% and 89%, respectively. Both patients received an imatinib (600 mg/day)-combined Hyper-CVAD regimen as induction therapy, followed by treatment with dasatinib (140 mg/day). MEC therapy was also applied between these two treatments in patient 2. At present, patient 1 has obtained complete molecular remission quantitatively and qualitatively, and patient 2 only quantitatively. Considering their acute onsets with no prior history of chronic myelocytic leukemia (CML), they were both diagnosed as having acute leukemia with Ph1, but not blastic crisis of CML. In this tyrosine kinase inhibitor era, it has become more difficult to differentiate these two types of Ph1-positive leukemia development.

Abstract
In this research, we propose a novel segmentation method for image of cultured cell at a confluent state, obtained by phase-contrast microscope, based on the orientation. First, we assign to each pixel in the image the direction of an eigenvector corresponding to a smaller eigenvalue of the 2 by 2 Hessian matrix with respect to brightness. Next, we define the orientation at a certain pixel as the histograms of the direction at pixels in the surrounding regions. Then, we evaluate deviation of histograms in the individual regions by entropy, and regard the series of entropy as a multi-dimensional vector, the dimension of which corresponds with the number of regions. We suppose that the vector is assigned to the pixel of interest. Finally, we segment the image based on the multi-dimensional vector using K-means method. We investigate the efficacy of the proposed method using an actual human confluent fibroblast image acquired by phase-contrast microscopy.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic follicular occlusive disease with characteristic recurrent draining sinuses, skin abscesses and disfiguring scars, mainly involving the axilla, groin, perianal and perineal regions. While most HS cases are nonfamilial, familial cases showing autosomal dominant inheritance have been reported. Recently, loss-of-function mutations in the genes encoding γ-secretase have been identified as a cause of familial HS in the Chinese and British populations. OBJECTIVES To identify mutations in the genes encoding γ-secretase in Japanese patients with familial and nonfamilial HS. METHODS Two affected and three unaffected individuals from a Japanese family with familial HS and nine patients with nonfamilial HS were recruited. We conducted mutation analysis of the γ-secretase genes in Japanese patients with familial and nonfamilial HS. RESULTS A novel splice site mutation in the nicastrin gene NCSTN, one of the six key component genes encoding γ-secretase, was identified in the patients with familial HS. Neither unaffected individuals in the family nor 100 ethnically matched control alleles carry this mutation. None of the nine patients with nonfamilial HS carry nonsense, frameshift or splice site mutations in this gene. CONCLUSIONS A novel splice site mutation, c.582+1delG, in NCSTN was identified in the familial patients with HS. We also reveal for the first time that a γ-secretase gene mutation is not linked to the development of nonfamilial HS. These results would further pave the way to a better understanding of the contribution of γ-secretase and other genes to the pathogenesis of HS and to the development of a new therapeutic strategy for HS.

Abstract
Aberrant expression of MIR9 predicts a poor prognosis in acute myelogenous leukemia. To evaluate its clinical significance in acute lymphoblastic leukemia, we analyzed expression levels of MIR9 in bone marrow samples from patients with acute lymphoblastic leukemia and compared them to those in normal bone marrow cells. Approximately 20% of them showed higher expression compared with controls. There was a tendency that patients who showed overexpression of MIR9 underwent worse clinical courses, but without statistical significance. However, when the analyses were restricted to patients who did not receive a stem cell transplant, overexpression of MIR9 was significantly associated with worse overall survival. Interestingly, exaggerated MIR9 expression and higher white blood cell count at presentation were independent unfavorable prognostic factors in all patients for overall survival by multivariate analysis. The presence of higher MIR9 expression could be a useful indicator for treatment stratification.

Abstract
AIM This study aimed to investigate the effects of vitamin C administration on skeletal muscle hypertrophy induced by mechanical overload in rats. METHODS Male Wistar rats were randomly assigned to three groups: (i) sham-operated group (n = 8), (ii) placebo-administered group (n = 8) and (iii) vitamin C-administered group (n = 8). In the placebo-administered and vitamin C-administered groups, the gastrocnemius and soleus muscles of the right hindlimb were surgically removed to overload the plantaris muscle. Vitamin C (500 mg kg(-1)) was orally administered to the vitamin C-administered group once a day for 14 days. RESULTS Synergist muscle ablation caused significant increases in wet weight and protein concentration of the plantaris muscle in both the placebo-administered (P < 0.01) and vitamin C-administered groups (P < 0.01) compared with the sham-operated group (SHA). However, the magnitude of plantaris muscle hypertrophy (expressed as a percentage of the contralateral plantaris muscle) was significantly smaller (P < 0.01) in the vitamin C-administered group (141%) than in the placebo-administered group (PLA) (152%). Compared with the SHA, only the PLA showed higher expressions of phosphorylated p70s6k and Erk1/2 (positive regulators of muscle protein synthesis) and a lower expression of atrogin-1 (a muscle atrophy marker). Concentrations of vitamin C and oxidative stress markers in the overloaded muscle were similar between the placebo-administered and vitamin C-administered groups. CONCLUSION Oral vitamin C administration can attenuate overload-induced skeletal muscle hypertrophy, which may have implications for antioxidant supplementation during exercise training.

Abstract
To investigate the precise effect of the redox potential on the methanogenesis of the hydrogenotrophic methanogen Methanothermobacter thermautotrophicus by using an electrochemical redox controlling system without adding oxidizing or reducing agents. A bioelectrochemical system was applied to control the redox conditions in culture and to measure the methane-producing activity of M. thermautotrophicus at a constant potential from +0·2 to -0·8 V (vs Ag/AgCl). Methane production and growth of M. thermautotrophicus were 1·6 and 3·5 times increased at -0·8 V, compared with control experiments without electrolysis, respectively, while methanogenesis was suppressed between +0·2 and -0·2 V. A clear relationship between an electrochemically regulated redox potential and methanogenesis was revealed.

Abstract
AIMS Multiple system atrophy (MSA) is pathologically characterized by the formation of α-synuclein-containing glial cytoplasmic inclusions (GCIs) in oligodendrocytes. However, the mechanisms of GCI formation are not fully understood. Cellular machinery for the formation of aggresomes has been linked to the biogenesis of the Lewy body, a characteristic α-synuclein-containing inclusion of Parkinson's disease and dementia with Lewy bodies. Here, we examined whether GCIs contain the components of aggresomes by immunohistochemistry. METHODS Sections from five patients with MSA were stained immunohistochemically with antibodies against aggresome-related proteins and analysed in comparison with sections from five patients with no neurological disease. We evaluated the presence or absence of aggresome-related proteins in GCIs by double immunofluorescence and immunoelectron microscopy. RESULTS GCIs were clearly immunolabelled with antibodies against aggresome-related proteins, such as γ-tubulin, histone deacetylase 6 (HDAC6) and 20S proteasome subunits. Neuronal cytoplasmic inclusions (NCIs) were also immunopositive for these aggresome-related proteins. Double immunofluorescence staining and quantitative analysis demonstrated that the majority of GCIs contained these proteins, as well as other aggresome-related proteins, such as Hsp70, Hsp90 and 62-kDa protein/sequestosome 1 (p62/SQSTM1). Immunoelectron microscopy demonstrated immunoreactivities for γ-tubulin and HDAC6 along the fibrils comprising GCIs. CONCLUSIONS Our results indicate that GCIs, and probably NCIs, share at least some characteristics with aggresomes in terms of their protein components. Therefore, GCIs and NCIs may be another manifestation of aggresome-related inclusion bodies observed in neurodegenerative diseases.

Abstract
A high volume of polyvinylpyrrolidone (PVP) supplementation in culture medium has a significant impact on the growth of bovine oocytes. The objective of the present study was to determine whether or not PVP affects oocyte growth in the mouse. Oocyte–granulosa cell complexes were isolated from 11- or 12-day-old mice (ICR) by mechanical isolation of follicles, followed by a collagenase treatment (0.1%; 10 min). Twenty complexes were placed on each insert fit in the 24-well culture plate and cultured for 10 days in an atmosphere of 5% CO2 in air at 37°C. The culture medium was a modified α-MEM supplemented with 5% fetal bovine serum and 1 ng mL–1 FSH. The concentration of PVP (molecular weight of 360 000) was 0%, 1%, 2%, or 3% (w/v). During the first 2 days, only medium with 0% PVP was used. The oocytes recovered on Day 10 were subjected to in vitro maturation, IVF, and embryo culture. In 12 replications, the total numbers of oocytes cultured in medium with 0%, 1%, 2%, and 3% PVP were 235, 233, 233, and 231, respectively. In some additional experiments, oocytes were fixed on Day 10 and processed for transmission electron microscopy (TEM). The oocytes in medium with 0% PVP became located within an enlarged dome-like structure. In medium with 2% PVP and 3% PVP, no such domes were formed, and the oocytes within several granulosa cell layers were exposed to medium; however, the cumulus cell mass specifically became larger than that in medium with 0% PVP. The viabilities of oocytes recovered from medium with 0%, 1%, 2%, and 3% PVP were 83%, 81%, 91%, and 93%, respectively. The survival rate was significantly higher in medium with 3% PVP than in medium with 0% PVP or 1% PVP (P < 0.05). The mean oocyte diameter increased from 59 µm (Day 0) to 72, 71, 71, and 72 µm in medium with 0, 1, 2, and 3% PVP, respectively, but they continued to be smaller than in vivo grown oocytes (81.0 µm; P < 0.01). When maturation was induced, cumulus cell mucification occurred irrespective of PVP concentration during the growth. No significant differences were found between the groups in the percentage of polar body extrusion (ranging from 78 to 88%). Developmental outcomes based on oocytes used for in vitro fertilization were the following: cleavage rates were 67, 78, 74, and 76%; and blastocyst rates were 37, 44, 47, and 36% of oocytes that had been grown in medium with 0, 1, 2, and 3% PVP, respectively. The numbers of oocytes included were 60, 59, 68, and 66, respectively. The TEM observation suggests that more intimate contacts were maintained between the oocyte and cumulus cells in medium with 2% PVP than in medium with 0% PVP. Taken together, PVP supplementation in medium has a considerable influence on the morphology of mouse oocyte–granulosa cell complexes and close contacts within the complexes in the long-term culture, as having been observed with bovine oocytes.

Abstract
An electron beam (EB) generated by a scanning electron microscope (SEM) was used to irradiate two samples having different thermal conductivities, and the resulting temperatures of the EB-irradiated areas as well as the temperature distributions within the samples were then measured using a thermal camera. These measurements showed overall increases in sample temperatures, as well as revealed temperature rises at the EB-irradiated areas that had little difference with one of the theoretical predictions. Differences between the actual and the predicted temperature measurements were analysed in terms of the accuracy with which parameters could be estimated. The temperature distributions of the samples were measured and, On the basis of the results, it was hypothesized that the temperature differential over an irradiated sample will be inversely correlated with its thermal conductivity.

Abstract
BALB 3T3 cells transfected by v-Ha-ras (Bhas 42 clone) were found to be sensitive to contact inhibition, but were susceptible to drastic transformation by 12-O-tetradecanoylphorbol-13-acetate. These results indicate that Bhas 42 cells are the initiated cells in the two-stage transformation process. By plating Bhas 42 cells together with BALB 3T3 cells followed by treatment with known promoters, a transformation assay system was established for the detection of tumour promoters. The Bhas 42 system showed advantages over conventional chemically induced transformation assays at several points, but some promoters did not induce transformation of Bhas 42 cells.

Abstract
Dopamine (DA) and juvenile hormone (JH) are multifunctional regulators of behaviour in social insects, with distinct effects across species and even between different dominance positions within the same species. We examined the effects of JH on the brain dopaminergic system in honey bee males to investigate the potential relationship between JH and DA within Apis mellifera. Both DA content and the expression of three DA receptor genes (Amdop1, Amdop2 and Amdop3) increased in the male honey bee brain from day 4 to day 8 after emergence. Treatment of 4-day-old males with a JH analogue (methoprene, JHA) enhanced brain DA levels. Brain expression of Amdop1 was also enhanced by JHA but not by a DA receptor agonist 2-amino 6,7-dihydroxy-1,2,3,4-tetrahydronaphthalene (6,7-ADTN), indicating that Amdop1 up-regulation was not mediated by increased DA receptor stimulation. Furthermore, Amdop1 expression was still enhanced when JHA was co-applied with the DA receptor antagonist cis-(Z)-flupenthixol. Expression levels of Amdop2 and Amdop3 were not altered by JHA, 6,7-ADTN or by JHA plus the DA receptor antagonist. Regulation of the brain dopaminergic system by JH, as observed in solitary species, is conserved in male honey bees but not in female honey bees and other advanced eusocial insects.

Abstract
We report a 69-year-old male with CD3-positive peripheral T-cell lymphoma, not otherwise specified (PTCL-nos). Interestingly, tumor cells slightly expressed CD20 as well. Southern analyses of the tumor cells showed rearrangement for only the T cell receptor gene but not the immunoglobulin genes. This patient achieved partial remission with a treatment regimen of THP-COP excluding prednisolone, but died of pneumonia. Although CD20-positive PTCL is rare, a review of the reported cases suggests that CD20-positive PTCL has a poor prognosis and that bone marrow infiltration of tumor cells results in a poorer prognosis in CD20-positive PTCL than in usual PTCL. By accumulating cases of this rare entity of lymphoma, we need to clarify the biological nature of the tumor cells and usefulness of rituximab combined with standard chemotherapy.

Abstract
We previously tested a less toxic CAG regimen consisting of low-dose cytarabine, aclarubicin and granulocyte-colony stimulating factor for the treatment of patients with relapsed or refractory myeloid malignancies or elderly patients with untreated ones, obtaining a satisfactory complete remission rate of 62%. Gemtuzumab ozogamicin, an anti-CD33 monoclonal antibody conjugated to calicheamicin, has recently been approved as a single agent in Japan for the treatment of relapsed/refractory CD33-positive acute myelogenous leukemia (9 mg/m(2) on days1 and 15). Complete remission rate was reported as 30% in a phase 2 trial in Japan. In this study, effectiveness and safety of combining dose-attenuated gemtuzumab ozogamicin (3 mg/m(2) on day5) and original CAG regimen were assessed in nine patients with relapsed/refractory CD33-positive acute myelogenous leukemia and a median age of 70 years. Rate of complete remission with or without platelet recovery was 44% (4/9). The median duration of complete remission and overall survival were 5.5 and 16 months, respectively. Reversible myelosuppression and liver toxicity were the main adverse events, but no regimen-related death was recorded. Although only a small number of cases were included in this preliminary study, this CAG-GO regimen was found to be feasible and useful even in high-risk relapsed or refractory patients.

Abstract
OBJECTIVE The relationship between lipid profiles and Alzheimer disease (AD) pathology at the population level is unclear. We searched for evidence of AD-related pathologic risk of abnormal lipid metabolism. METHODS This study included brain specimens from a series of 147 autopsies performed between 1998 and 2003 of residents in Hisayama town, Japan (76 men and 71 women), who underwent clinical examinations in 1988. Lipid profiles, such as total cholesterol (TC), triglycerides, and high-density lipoprotein cholesterol (HDLC), were measured in 1988. Low-density lipoprotein cholesterol (LDLC) was calculated using the Friedewald formula. Neuritic plaques (NPs) were assessed according to the Consortium to Establish a Registry for Alzheimer's Disease guidelines (CERAD) and neurofibrillary tangles (NFTs) were assessed according to Braak stage. Associations between each lipid profile and AD pathology were examined by analysis of covariance and logistic regression analyses. RESULTS Adjusted means of TC, LDLC, TC/HDLC, LDLC/HDLC, and non-HDLC (defined as TC-HDLC) were significantly higher in subjects with NPs, even in sparse to moderate stages (CERAD = 1 or 2), compared to subjects without NPs in multivariate models including APOE ε4 carrier and other confounding factors. The subjects in the highest quartiles of these lipid profiles had significantly higher risks of NPs compared to subjects in the lower respective quartiles, which may suggest a threshold effect. Conversely, there was no relationship between any lipid profile and NFTs. CONCLUSION The results of this study suggest that dyslipidemia increases the risk of plaque-type pathology.

Biomineral hydroxyapatite (Bio-HAp) produced by Serratia sp. has the potential to be a suitable material for the remediation of metal contaminated waters and as a radionuclide waste storage material. Varying the Bio-HAp manufacturing method was found to influence hydroxyapatite (HAp) properties and consequently the uptake of Sr(2+) and Co(2+). All the Bio-HAp tested in this study were more efficient than the commercially available hydroxyapatite (Com-HAp) for Sr(2+) and Co(2+) uptake. For Bio-HAp the uptake for Sr(2+) and Co(2+) ranged from 24 to 39 and 29 to 78 mmol per 100 g, respectively. Whereas, the uptake of Sr(2+) and Co(2+) by Com-HAp ranged from 3 to 11 and 4 to 18 mmol per 100 g, respectively. Properties that increased metal uptake were smaller crystallite size (<40 nm) and higher surface area (>70 m(2) g(-1)). Organic content which influences the structure (e.g., crystallite arrangement, size and surface area) and composition of Bio-HAp was also found to be important in Sr(2+) and Co(2+) uptake. Overall, Bio-HAp shows promise for the remediation of aqueous metal waste especially since Bio-HAp can be synthesized for optimal metal uptake properties.

Abstract
We identified a sex-linked, recessive body color gene, presently designated w (whitish-yellow), in the frog Rana rugosa from the Iwakuni population in Western Japan. This is the first time a sex-linked body color gene was found in amphibians so far. In this population of R. rugosa, males are the heterogametic sex, but the sex chromosomes are still homomorphic. When heterozygous males (Ww), which were produced by crossing a whitish-yellow female (ww) found in the field and a wild-type male (WW) of the same population, were backcrossed to the homozygous whitish-yellow female (ww), the resultant male offspring were all wild-type, whereas the females were all whitish-yellow. This result definitely indicates that w is recessive and X-linked, and its wild-type allele W is located on the Y chromosome. Using this strain (X(w)X(w) female and X(w)Y(W) male), we found that expression of Dmrt1 and Rspo1, which are involved in testicular and ovarian differentiation in vertebrates, was higher in males and females, respectively, prior to the onset of the sexually dimorphic expression of Cyp17 and Cyp19, which are involved in biosynthesis of sex steroids and are critical markers of gonadal sex differentiation.

Abstract
The T2K experiment observes indications of ν(μ) → ν(e) appearance in data accumulated with 1.43×10(20) protons on target. Six events pass all selection criteria at the far detector. In a three-flavor neutrino oscillation scenario with |Δm(23)(2)| = 2.4×10(-3) eV(2), sin(2)2θ(23) = 1 and sin(2)2θ(13) = 0, the expected number of such events is 1.5±0.3(syst). Under this hypothesis, the probability to observe six or more candidate events is 7×10(-3), equivalent to 2.5σ significance. At 90% C.L., the data are consistent with 0.03(0.04) < sin(2)2θ(13) < 0.28(0.34) for δ(CP) = 0 and a normal (inverted) hierarchy.

Abstract
Two young adults underwent resection of large hypervascular vestibular schwannomas (acoustic neuromas) via two-stage surgery. The first patient, a 27-year-old woman with hydrocephalus, had a large hypervascular vestibular tumor in the left cerebellopontine angle (CPA) supplied by the left anterior inferior cerebellar artery (AICA) and posterior inferior cerebellar artery (PICA). The second patient, a 34-year-old woman, had a large AICA-supplied hypervascular vestibular tumor in the left CPA that displaced the brain stem significantly. At the initial stage, only the lateral aspect of the tumor was debulked due to excessive bleeding from the tumor bed. Angiography 1 or 2 months after the initial operation showed that the tumor was hypovascular. At the second stage, the remnant medial aspect of the tumor was relatively avascular and nonadherent to the brain stem. Without blood transfusion during the second stage, the tumor was removed totally in the first patient and subtotally in the second patient. Pathological examination revealed that dilatated blood vessels were prominently increased at the first surgery; however, at the second surgery, the number of blood vessels had decreased, showing necrosis and degeneration. Although there are no absolute indications for the staged resection of vestibular schwannomas, this procedure may represent one of the safest options for these difficult lesions in young adults.

Abstract
We examined the reliability of radiological findings in predicting segmental instability in 112 patients (56 men, 56 women) with a mean age of 66.5 years (27 to 84) who had degenerative disease of the lumbar spine. They underwent intra-operative biomechanical evaluation using a new measurement system. Biomechanical instability was defined as a segment with a neutral zone > 2 mm/N. Risk factor analysis to predict instability was performed on radiographs (range of segmental movement, disc height), MRI (Thompson grade, Modic type), and on the axial CT appearance of the facet (type, opening, vacuum and the presence of osteophytes, subchondral erosion, cysts and sclerosis) using multivariate logistic regression analysis with a forward stepwise procedure. The facet type was classified as sagittally orientated, coronally orientated, anisotropic or wrapped. Stepwise multivariate regression analysis revealed that facet opening was the strongest predictor for instability (odds ratio 5.022, p = 0.009) followed by spondylolisthesis, MRI grade and subchondral sclerosis. Forward stepwise multivariate logistic regression indicated that spondylolisthesis, MRI grade, facet opening and subchondral sclerosis of the facet were risk factors. Symptoms evaluated by the Short-Form 36 and visual analogue scale showed that patients with an unstable segment were in significantly more pain than those without. Furthermore, the surgical procedures determined using the intra-operative measurement system were effective, suggesting that segmental instability influences the symptoms of lumbar degenerative disease.

Abstract
Selective laser melting (SLM) is a useful technique for preparing three-dimensional porous bodies with complicated internal structures directly from titanium (Ti) powders without any intermediate processing steps, with the products being expected to be useful as a bone substitute. In this study the necessary SLM processing conditions to obtain a dense product, such as the laser power, scanning speed, and hatching pattern, were investigated using a Ti powder of less than 45 μm particle size. The results show that a fully dense plate thinner than 1.8 mm was obtained when the laser power to scanning speed ratio was greater than 0.5 and the hatch spacing was less than the laser diameter, with a 30 μm thick powder layer. Porous Ti metals with structures analogous to human cancellous bone were fabricated and the compressive strength measured. The compressive strength was in the range 35-120 MPa when the porosity was in the range 75-55%. Porous Ti metals fabricated by SLM were heat-treated at 1300 °C for 1h in an argon gas atmosphere to smooth the surface. Such prepared specimens were subjected to NaOH, HCl, and heat treatment to provide bioactivity. Field emission scanning electron micrographs showed that fine networks of titanium oxide were formed over the whole surface of the porous body. These treated porous bodies formed bone-like apatite on their surfaces in a simulated body fluid within 3 days. In vivo studies showed that new bone penetrated into the pores and directly bonded to the walls within 12 weeks after implantation into the femur of Japanese white rabbits. The percentage bone affinity indices of the chemical- and heat-treated porous bodies were significantly higher than that of untreated implants.

Abstract
148 Background: A phase I/II study of adenovirus-mediated interleukin-12 (IL–12) gene therapy for castration resistant prostate cancer has been initiated from May 2008 in Okayama University Hospital. Interim results of 10 cases including a positive clinical response are reported. Methods: Major inclusion criteria was a recurrence of prostate cancer following hormonal therapy with/without metastasis. Replication–defective adenovirus vector expressing IL–12 (Adv.IL–12) was injected directly into the prostate (or metastatic lesion in patients who received prostatectomy) in escalating doses from 1.0×1010 to 5.0×1012 viral particle (vp). GMP grade vector was produced at Center for Cell and Gene Therapy, Baylor College of Medicine (Director: Malcolm K. Brenner). Each patient received total of 3 times viral injections every 4 weeks. In addition to the safety profile, cancer control efficacy and immunological changes after viral injections were evaluated. Results: Ten patients received the gene therapy in doses of 1.0×1010 to 5.0×1011 vp from May 2008 to October 2010. 9 cases completed, and 1 patient dropped out the study because of rapid cancer progression. Major adverse effects are following: urinary retention (G1), trasaminase elevation (G3), fever up (G3). These adverse effects were rapidly disappeared after proper treatments. One patient with highest dose (5.0×1011 vp) showed some clinical positive responses (PSA decrease, shrinkage of lymphnode metastasis), therefore received an additional viral injection. Temporal decreases just after each vector injections and gradual increases at the peak of 7-14 days after each vector injections in some immunocompetent cells (CD3+CD19–, CD3–CD19– CD16+CD56+, CD3+CD4–CD8–) were seen in relatively high dose group. Elevations of serum cytokines were observed in parallel with vector dose escalation. Conclusions: This interim report suggests the favorable safety profile and positive clinical responses in a clinical trial of Adv.IL–12 gene therapy for hormone refractory prostate cancer in higher doses of viral vectors. Further evaluations in the next higher vector doses are needed and in progress. No significant financial relationships to disclose.

Abstract
Flavonoids are natural compounds found in many plants, including the important fruit crop, tomato. Prenylated flavonoids consist of a large group of compounds, which often exhibit antitumour, antibacterial and/or anti-androgen activities. In this study, we engineered the biosynthesis of prenylated flavonoids using a Streptomyces prenyltransferase HypSc (SCO7190) possessing broad-range substrate specificity, in tomato as a host plant. LC/MS/MS analysis demonstrated the generation of 3'-dimethylallyl naringenin in tomato fruits when recombinant HypSc protein was targeted to the plastids, whereas the recombinant protein hardly produced this compound in vitro. This is the first report confirming the accumulation of a prenylated flavonoid using a bacterial prenyltransferase in transgenic plants, and our results suggest that the product specificities of prenyltransferases can be significantly influenced by the host plant.

Abstract
ABSTRACTAll-optical switches and all-optical bistabili ties are realized by waveguide structures with vacuum evaporated polydiacetylene(PDA) films. The basic structure of the all-optical switches are prepared in the form of layered waveguide directional coupler with vacuum evaporated PDA top layer. Clearly switchings are observed at 1064nm of pulsed Nd:YAG laser. Furthermore ultra-high speed switching with Ti;Safire 135fs laser are recognized.Operations of all-optical bistabilities are carried out by nonlinear coupling at grating structures in waveguides with PDA top layers. Hysterisis curves of bistability are affected by coupling parameters of gratings and parameters of waveguides.

Abstract
Effective immobilization of boron in groundwater is a major challenge. Permeable reactive barrier (PRB) column tests for removal of borate have been investigated using MgO agglomerates as the primary reactive material over 40 weeks. Additionally, saw dust was also blended with MgO agglomerates to facilitate for borate removal in this system. Boron accumulation was more than 1.6 times greater in the presence of saw dust, although MgO alone performed well. Increased boron accumulation in the presence of saw dust was primarily due to higher porosity of the PRB column, decreasing the impact of secondary Mg(OH)(2) passivating layers and leaving more reactive sites on MgO agglomerates. In addition, Mg(2+) ions released from MgO agglomerates are complexed with carboxylic acids leached from saw dusts. This sequestration prevents the formation of bulky Mg(OH)(2) which is an ineffective sorbent for borate and covers the surfaces and passivating reactive sites on the MgO agglomerates. The morphologies of Mg(OH)(2) precipitated in the PRB column were also significantly affected by the presence of saw dust, with crystallization of needle-like particles of Mg(OH)(2) was prevented by Mg(2+) ions-organic ligand complexation.
