Abstract
BACKGROUND AND AIMS Patients with prolapsing internal hemorrhoids were treated with a novel sclerosing agent (OC-108), and the results were compared with surgery of ligation and excision. PATIENTS AND METHODS This study included 20 years or older patients with prolapsing internal hemorrhoids who visited ten medical institutions in Japan from October 2000 to October 2002. Investigation on surgery was also performed. RESULTS Comparing OC-108 and surgery in patients with third- and fourth-degree internal hemorrhoids according to the Goligher's classification, for which surgery has been generally indicated, at 28 days after treatment, the disappearance rate of prolapse was similar between OC-108 and surgery, 94% (75/80 patients) and 99% (84/85 patients), respectively. The 1-year recurrence rate was 16% (12/73 patients) in the OC-108 group, and this value was satisfactory because of its less invasive nature while it was more or less higher compared with 2% (2/81 patients) in the surgery group. The incidences of pain and bleeding were lower in the OC-108 group. CONCLUSIONS OC-108 is a useful alternative treatment for hemorrhoids.

Abstract
A plasmid, pNT4553, was constructed for high level production of N-carbamyl-d-amino acid amidohydrolase (DCase), the thermostability of which has been improved by amino acid substitution. The DCase activity and the stability of the plasmid in the host cells were dependent on the Escherichia coli strains used. E. coli HB101 was the most suitable host strain among the 13 types of E. coli tested. E. coli HB101 exhibited the highest activity, i.e. 6.36 units/ml of culture broth in 2YT medium (1.6% tryptone, 1.0% yeast extract, and 0.5% NaCl, pH 7.0), and the plasmid was stably maintained by cultivation in 5 types of E. coli including HB101. Casamino acids, NZ-amine, peptone, and protein extract (a mixture of hydrolyzates of corn gluten, wheat gluten and soybean), were found to be suitable as natural nitrogen sources for both enzyme activity and growth. When cultivation was carried out in the presence of high concentrations of glycerol (6.5%) as the carbon source, and protein extract (3.0%) as the nitrogen source, in a small volume of the medium (20 ml of medium in a 500-ml shaking flask), in which the aeration level was estimated to be high, growth and activity reached OD550=63.8 (17.1 mg of dry cell weight/ml of culture broth) and 22.9 units/ml of culture broth, respectively. The economical hyperproduction of DCase using only inexpensive constituents for the medium was achieved.

Abstract
We previously demonstrated that cAMP-dependent protein kinase was reduced in the dendrites of MAP2-deficient mice. In this study, we compared the expression of various protein phosphatases (PPs) between wild-type and map2(-/-) dendrites. Kinase-associated phosphatase (KAP) was the only PP which showed difference between the two phenotypes: (1) the expression of KAP was reduced in map2(-/-) cortical dendrites, and (2) the amount of KAP bound to microtubules was reduced in map2(-/-) brains. We also demonstrated in cultured neuroblastoma cells that KAP is not only expressed in dividing cells, but also in the neurites of differentiated cells. Our findings propose that KAP, which has been reported to function in cell-cycle control, has an as yet uncovered role in regulating dendritic functions. We also propose MAP2-deficient mice as an ideal system for identifying protein phosphatases essential for dendritic functions.

Abstract
The transport of prostaglandin E(1) (PGE(1)) across the blood-brain barrier (BBB) was characterized using an in-situ rat brain perfusion technique. The uptake of [(3)H]PGE(1) was not affected by shortchain monocarboxylic acids (butyric acid and valeric acid). On the other hand, uptake of [(3)H]PGE(1) was significantly inhibited by medium-chain monocarboxylic acids such as hexanoic acid, enanthic acid and octanoic acid. These medium-chain monocarboxylic acids showed a more potent inhibitory effect on [(3)H]PGE(1) uptake with increasing number of carbon atoms. In contrast, there was no decrease in [(3)H]PGE(1) transport by any dicarboxylic acids with 5-8 carbon atoms. Valproic acid decreased [(3)H]PGE(1) uptake, whereas p-aminohippuric acid, a substrate for the organic anion transporter family, did not inhibit [(3)H]PGE(1) transport. Bromocresol green, an inhibitor of prostaglandin transporter (PGT), strongly decreased [(3)H]PGE(1) transport across the BBB. In addition, digoxin and taurocholate, substrates for organic anion transporting polypeptide subtype 2 (Oatp2), significantly inhibited [(3)H]PGE(1) uptake. RT-PCR analysis revealed that PGT mRNA and Oatp2 mRNA are expressed in a capillary-rich fraction from rat brain. Thus, it is suggested that PGE(1) transport across the BBB is mediated by some specific transport systems, possibly by the members of the Oatp family.

Abstract
Understanding the role of competing states in the cuprates is essential for developing a theory for high-temperature superconductivity. We report angle-resolved photoemission spectroscopy experiments which probe the 4a0 x 4a0 charge-ordered state discovered by scanning tunneling microscopy in the lightly doped cuprate superconductor Ca2-xNaxCuO2Cl2. Our measurements reveal a marked dichotomy between the real- and momentum-space probes, for which charge ordering is emphasized in the tunneling measurements and photoemission is most sensitive to excitations near the node of the d-wave superconducting gap. These results emphasize the importance of momentum anisotropy in determining the complex electronic properties of the cuprates and places strong constraints on theoretical models of the charge-ordered state.

Abstract
The evolution of Ca2-xNaxCuO2Cl2 from Mott insulator to superconductor was studied using angle-resolved photoemission spectroscopy. By measuring both the excitations near the Fermi energy as well as nonbonding states, we tracked the doping dependence of the electronic structure and the chemical potential with unprecedented precision. Our work reveals failures in the standard weakly interacting quasiparticle scenario, including the broad line shapes of the insulator and the apparently paradoxical shift of the chemical potential within the Mott gap. To resolve this, we develop a model where the quasiparticle is vanishingly small at half filling and grows upon doping, allowing us to unify properties such as the dispersion and Fermi wave vector with the chemical potential.

Abstract
We developed an in vivo electroporation method to introduce foreign genes into retinal ganglion cells (RGCs). After the intravitreous injection of the plasmid gene (20 mug), five electric pulses (6 V/cm, 100 ms duration) were each delivered twice with 5 min interval to the rat eye using a contact lens-type electrode (cathodal) attached to the cornea and a needle electrode (anodal) inserted to the middle of the forehead. The efficiency of the genetic introduction into RGCs and tissue damage to the eyeball was evaluated using a green fluorescent protein (GFP) gene, TUNEL and histological observation. DiI retrograde labeling revealed that 24.4 +/- 4.7% of all RGCs were electrointroduced with the GFP gene. TUNEL and histological analysis showed a few tissue damages in the cornea, lens and retina. To confirm whether this method can actually rescue damaged RGCs, glial cell line-derived neurotrophic factor (GDNF) was electrointroduced into RGCs after optic nerve transection. After the electrointroduction, a significant increase in the number of surviving RGCs was observed 2 and 4 weeks after the optic nerve transection, and the decrease of caspase 3 and 9 was detected by RT-PCR. These results suggest that this method may be useful for the delivery of genes into RGCs with simplicity and minimal tissue damage.

Abstract
A new scenario for neutron-star cooling is suggested by the correspondence between pion condensation, induced by critical spin-isospin fluctuations, and the metal-insulator phase transition in a 2D electron gas. Above the threshold density for pion condensation, the neutron single-particle spectrum acquires an insulating gap that quenches neutron contributions to neutrino production. In the liquid phase just below the transition, the fluctuations play dual roles by (i) creating a multisheeted neutron Fermi surface that extends to low momenta and activates the normally forbidden direct Urca cooling mechanism, and (ii) amplifying the nodeless P-wave neutron superfluid gap while suppressing S-wave pairing. Lighter stars without a pion-condensed core undergo slow cooling, whereas enhanced cooling occurs in heavier stars via direct Urca emission from a thin shell of the interior.

Abstract
The spatial variation of electronic states was imaged in the lightly doped Mott insulator Ca(2-x)NaxCuO2Cl2 using scanning tunneling microscopy or spectroscopy. We observed nanoscale domains with a high local density of states within an insulating background. The observed domains have a characteristic length scale of 2 nm (approximately 4-5a, a: lattice constant) with preferred orientations along the tetragonal [100] direction. We argue that such spatially inhomogeneous electronic states are inherent to slightly doped Mott insulators and play an important role for the insulator to metal transition.

Abstract
The phase diagram of hole-doped copper oxides shows four different electronic phases existing at zero temperature. Familiar among these are the Mott insulator, high-transition-temperature superconductor and metallic phases. A fourth phase, of unknown identity, occurs at light doping along the zero-temperature bound of the 'pseudogap' regime. This regime is rich in peculiar electronic phenomena, prompting numerous proposals that it contains some form of hidden electronic order. Here we present low-temperature electronic structure imaging studies of a lightly hole-doped copper oxide: Ca2-xNaxCuO2Cl2. Tunnelling spectroscopy (at energies |E| > 100 meV) reveals electron extraction probabilities greatly exceeding those for injection, as anticipated for a doped Mott insulator. However, for |E| < 100 meV, the spectrum exhibits a V-shaped energy gap centred on E = 0. States within this gap undergo intense spatial modulations, with the spatial correlations of a four CuO2-unit-cell square 'checkerboard', independent of energy. Intricate atomic-scale electronic structure variations also exist within the checkerboard. These data are consistent with an unanticipated crystalline electronic state, possibly the hidden electronic order, existing in the zero-temperature pseudogap regime of Ca2-xNaxCuO2Cl2.

Abstract
The aim of this study was to analyze the iodine-unstained region expanding around oral squamous cell carcinoma (SCC) by quantification of telomerase activity. The epithelial dysplasia often observed around SCC is considered to cause local recurrence or a second primary cancer. However these areas are hard to distinguish from normal mucosa. To clear the border of the expanding epithelial dysplasia around SCC, we stained with 3% iodine solution, and then decided the surgical margin. We measured quantification of telomerase activity in tumor, in epithelial dysplasia, and also in normal epithelium. Thirty-three primary cases of oral SCC which have iodine-unstained region around lesions were investigated. Fluorescense-based TRAP was applied to obtain quantification of telomerase activity. We obtained the following results: histological examination confirmed that every patient's unstained region consisted of various degrees of epithelial dysplasia. The quantified telomerase activities for squamous cell carcinoma, epithelial dysplasia and normal epithelium were 53.9, 39.6 and 2.7 U/microgP, respectively, and there was a significant difference between carcinoma and normal areas, and between dysplasia and normal epithelium. Therefore, these findings suggest that the areas of epithelial dysplasia unstained by iodine consist of cells that are nearly cancerous and excessively proliferative, and that epithelial dysplasia around SCC should be resected together with the tumor. Vital staining with iodine is useful for identifying epithelial dysplasia around SCC.

Abstract
For high luminosity in electron-positron linear colliders, it is essential to generate low vertical emittance beams. We report on the smallest vertical emittance achieved in single-bunch-mode operation of the Accelerator Test Facility, which satisfies the requirement of the x-band linear collider. The emittances were measured with a laser-wire beam-profile monitor installed in the damping ring. The bunch length and the momentum spread of the beam were also recorded under the same conditions. The smallest vertical rms emittance measured at low intensity is 4 pm at a beam energy of 1.3 GeV, which corresponds to the normalized emittance of 1.0x1.0(-8) m. It increases by a factor of 1.5 for a bunch intensity of 10(10) electrons. The measured data agreed to the calculation of intrabeam scattering within much better than a factor of 2.

Ultrasonography revealed mucus retention in the uterine cavity and bilateral multicystic ovaries during ovulation induction. Atypical hyperplasia was diagnosed by endometrial curettage. Repeated procedures including ovarian cystectomy, endometrial curettage and in vitro fertilization combined with progestine therapy resulted in no pregnancy but rapid recurrences. She finally underwent simple hysterectomy and bilateral salpingo-oophorectomy.

Abstract
X-ray anomalous diffraction, together with a band-structure calculation, was employed to obtain a quantitative understanding of the charge-ordering state in a single-crystalline CaFeO3 thin film. The experimental result shows a characteristic energy dispersion of the nearly inhibited reflection at 150 K, implying Fe atoms split into two distinct states. The energy dispersion is in good agreement with the calculated spectrum based on the LDA+U scheme. The calculation also reveals an electronic structure of the system where holes in the oxygen orbital surround one of the distinct Fe atoms, in spite of the total electron number in both Fe atoms remaining unchanged.

Abstract
BACKGROUND Recent mucosal biopsy criteria combined with endoscopy effectively differentiate patients with ulcerative colitis ultimately requiring surgery (UC-S) from those receiving medication alone (UC-M). However, the criteria were inconvenient in practical use because of the need for complicated calculations, and the validity has not been verified in other institutes where the indications for surgery may differ. The aims of this multicenter study were to propose simple criteria in which calculation can be performed by mental arithmetic and to measure their validity. METHODS Based on the above original criteria, we constructed simple criteria in which coefficients and constant were simplified to integral numbers. The criteria consisted of the diagnostic categories, highest-risk, high-risk, unpredictable, low-risk, and lowest-risk of surgery. The validity of these proposed criteria was evaluated in 121 patients with UC-S and 186 with UC-M from 11 institutes. RESULTS The categories of high-risk and low-risk had sensitivities exceeding 86.0% and specificities exceeding 95.2%, and the validities were maintained at high levels in most individual institutes. There was little difference in validity between the proposed and original criteria when testing using the same patients. CONCLUSIONS Despite simplified coefficients and constant, the proposed criteria reliably predicted the eventual clinical outcome of patients with ulcerative colitis and would be helpful in determining the necessity of surgery.
