Abstract
To establish a basic strategy for prevention of aspiration pneumonia in patients with motor and intellectual disabilities, we investigated oral opportunistic pathogen (OOP) infections in 31 such patients who were resident at a welfare home. Patients received special oral care from a dental hygienist once a week. OOP samples were collected by scraping the dorsal surface of the tongue, and then cultured. For each patient, the basic reasons for admission and the degree of intellectual disability and mobility were recorded. OOPs were found in 61.3% of the patients, of which methicillin-sensitive Staphylococcus aureus (MSSA) was the most commonly detected (38.7%). A significantly high proportion of male patients were OOP-positive, and a significantly high proportion of patients with mental retardation were Candida sp.-positive. However, multivariate logistic regression revealed that disability was not associated with OOP positivity. No correlation was found between OOP positivity and disability. Nevertheless, special oral care may be beneficial for maintenance of oral health in patients with disabilities.

Abstract
This paper presents a new method, Minimax Tree Optimization (MMTO), to learn a heuristic evaluation function of a practical alpha-beta search program. The evaluation function may be a linear or non-linear combination of weighted features, and the weights are the parameters to be optimized. To control the search results so that the move decisions agree with the game records of human experts, a well-modeled objective function to be minimized is designed. Moreover, a numerical iterative method is used to nd local minima of the objective function, and more than forty million parameters are adjusted by using a small number of hyper parameters. This method was applied to shogi, a major variant of chess in which the evaluation function must handle a larger state space than in chess. Experimental results show that the large-scale optimization of the evaluation function improves the playing strength of shogi programs, and the new method performs signicantly better than other methods. Implementation of the new method in our shogi program Bonanza made substantial contributions to the program's rst-place nish in the 2013 World Computer Shogi Championship. Additionally, we present preliminary evidence of broader applicability of our method to other two-player games such as chess.

Abstract
Using exact numerical techniques, we investigate the nature of excitonic (electron-hole) bound states and the development of exciton coherence in the one-dimensional half-filled extended Falicov-Kimball model. The ground-state phase diagram of the model exhibits, besides band-insulator and staggered orbital ordered phases, an excitonic insulator (EI) with power-law correlations. The criticality of the EI state shows up in the von Neumann entropy. The anomalous spectral function and condensation amplitude provide the binding energy and coherence length of the electron-hole pairs which, on their part, point towards a Coulomb interaction driven crossover from BCS-like electron-hole pairing fluctuations to tightly bound excitons. We show that while a mass imbalance between electrons and holes does not affect the location of the BCS-BEC crossover regime, it favors staggered orbital ordering to the disadvantage of the EI. Within the Bose-Einstein condensation (BEC) regime, the quasiparticle dispersion develops a flat valence-band top, in accord with the experimental finding for Ta2NiSe5.

Abstract
The rat has been used as an important animal for understanding human diseases. Genetically engineered rat strains are used as a human disease model in various research fields. Genetically engineered rat strains are now being routinely produced, not only as transgenic animals but also using gene knockout techniques. Recently, zinc finger nucleases (ZFN) and TAL effector nucleases (TALEN) have enabled editing targeted genes without using embryonic stem cells. These techniques have been applied for production of the knockout and knockin animals. We here studied that the effects of gene targeting by ZFN and TALEN introduced into rat embryos for efficient production of knockout rats. We custom-designed ZFN and TALEN plasmids targeted rat interleukin 2 receptor gamma (Il2rg) gene. Each mRNA was transcribed in vitro from these plasmids. Final concentration of mRNA was adjusted at 10 ng μL–1 in sterilized water for microinjection. Messenger RNA was injected into rat pronuclear stage embryos. The embryos were then cultured in vitro to the 2-cell stage, and were transferred into oviducts of pseudopregnant females. The rate of development of offspring of embryos and effects of editing targeted genes were examined. Of 41 two-cell embryos introduced ZFN after embryo transfer, 9 embryos (22%) developed to offspring. Three offspring (33%) had an edited targeted gene locus. In the embryos introduced TALEN, 30% (6 offspring) of embryos developed to offspring after embryo transfer and all offspring had an edited targeted gene locus. This study demonstrated that the ZFN and TALEN mRNA was active after introduction into rat embryos. Knockout rats could be produced by introduction of ZFN and TALEN into rat embryos. ZFN and TALEN will provide a powerful new approach for targeted gene editing not only in rats but also in other animal species.

Abstract
Enkephalin (ENK) has been postulated to play important roles in modulating nociceptive transmission, and it has been proved that ENKergic neurons acted as a critical component of sensory circuit in the adult spinal cord. Revealing the developmental characteristics of spinal ENKergic neurons will be helpful for understanding the formation and alteration of the sensory circuit under pain status. However, the relationship between the embryonic birth date and the adult distribution of ENKergic neurons has remained largely unknown due to the difficulties in visualizing the ENKergic neurons clearly. Taking advantage of the preproenkephalin-green fluorescent protein (PPE-GFP) transgenic mice in identifying ENKergic neurons, we performed the current birth-dating study and examined the spinal ENKergic neurogenesis. The ENKergic neurons born on different developmental stages and their final location during adulthood were investigated by combining bromodeoxyuridine (BrdU) incorporation and GFP labeling. The spinal ENKergic neurogenesis was restricted at E9.5 to E14.5, and fitted in the same pattern of spinal neurogenesis. Further comparative analysis revealed that spinal ENKergic neurons underwent heterogeneous characteristics. Our study also indicated that the laminar arrangement of ENKergic neurons in the superficial spinal dorsal horn depended on the neurogenesis stages. Taken together, the present study suggested that the birth date of ENKergic neurons is one determinant for their arrangement and function.

Abstract
Complete deficiency of the fourth component of complement (C4) is an extremely rare condition. However, it has been reported that partial C4 deficiency can occur in normal subjects, and is associated with several immune diseases. We report a 44-year-old woman who developed slight oedema and punctate purpura on her lower legs after a common cold. She was noted to have persistent microscopic haematuria and proteinuria, and her C4 level was undetectable. On histological examination of a skin biopsy specimen, leucocytoclastic vasculitis was seen, with granular deposition of IgG, IgM, C3 and C1q on the vessel walls in the upper dermis. A renal biopsy showed mild mesangial proliferative glomerulonephritis with slight damage to the capillary loops, and granular deposits of IgM and C4 mainly in the mesangium. The patient was systemically well and needed no medication. The C4 level remained low during the observation period, but neither genotyping nor allotyping analysis identified a C4 deficiency.

Abstract
BACKGROUND No scoring system has ever been used to estimate the prognosis of individual tuberculosis (TB) patients. OBJECTIVE To develop and validate a tuberculosis prognostic score. METHODS This retrospective cohort study conducted in Japan comprised the development (n = 179; mean age 65.9 ± 18.8 years) and validation (n = 244; mean age 64.3 ± 20.1 years) of a tuberculosis prognostic score among patients with newly diagnosed smear-positive non-multidrug-resistant pulmonary tuberculosis without human immunodeficiency virus infection. The score (raw score) was defined by modifying a logistic regression formula using known risk factors as independent variables and in-patient death as a dependent variable. RESULTS The raw score was calculated as follows: age (years) + (oxygen requirement, 10 points) - 20 × albumin (g/dl) + (activity of daily living: independent, 0 point; semi-dependent, 5 points; totally dependent, 10 points). The raw scores were grouped into risk groups 1 (raw score < -30) to 5 (raw score ≥ 60) using 30-point intervals. Every increase in risk group was equivalent to a 7.3-fold increase in the odds ratio for in-hospital death (P < 0.001). The area under the receiver operating characteristics curve by risk group for in-patient death was 0.875 (P < 0.001). CONCLUSIONS In this study we were able to develop and validate a tuberculosis prognostic score.
