Abstract
OBJECTIVES To identify the molecular etiology of distinct dental anomalies found in eight Thai patients and explore the mutational effects on cellular functions. MATERIALS AND METHODS Clinical and radiographic examinations were performed for eight patients. Whole exome sequencing, mutant protein modelling, qPCR, western blot analysis, scratch assays, immunofluorescence, confocal analysis, in situ hybridization, and scanning electron micrography of teeth were done. RESULTS All patients had molars with multiple supernumerary cusps, single-cusped premolars, and a reduction in root number. Mutation analysis highlighted a heterozygous c.865A>G; p.Ile289Val mutation in CACNA1S in the patients. CACNA1S is a component of the slowly inactivating L-type voltage-dependent calcium channel. Mutant protein modeling suggested that the mutation might allow leakage of Ca2+ or other cations, or a tightening, to restrict calcium flow. Immunohistochemistry analysis showed expression of Cacna1s in the developing murine tooth epithelium during stages of crown and root morphogenesis. In cell culture, the mutation resulted in abnormal cell migration of transfected CHO cells compared to wildtype CACNA1S, with changes to the cytoskeleton and markers of focal adhesion. CONCLUSIONS The malformations observed in our patients suggest a role for calcium signaling in organization of both cusps and roots, affecting cell dynamics within the dental epithelium.

Abstract
High-power, short-pulse laser-driven fast electrons can rapidly heat and ionize a high-density target before it hydrodynamically expands. The transport of such electrons within a solid target has been studied using two-dimensional (2D) imaging of electron-induced Kα radiation. However, it is currently limited to no or picosecond scale temporal resolutions. Here, we demonstrate femtosecond time-resolved 2D imaging of fast electron transport in a solid copper foil using the SACLA x-ray free electron laser (XFEL). An unfocused collimated x-ray beam produced transmission images with sub-micron and ∼10 fs resolutions. The XFEL beam, tuned to its photon energy slightly above the Cu K-edge, enabled 2D imaging of transmission changes induced by electron isochoric heating. Time-resolved measurements obtained by varying the time delay between the x-ray probe and the optical laser show that the signature of the electron-heated region expands at ∼25% of the speed of light in a picosecond duration. Time-integrated Cu Kα images support the electron energy and propagation distance observed with the transmission imaging. The x-ray near-edge transmission imaging with a tunable XFEL beam could be broadly applicable for imaging isochorically heated targets by laser-driven relativistic electrons, energetic protons, or an intense x-ray beam.

Abstract
Inflammasomes are cytosolic complexes composed of a Nod-like receptor, NLR, the adaptor protein, ASC, and a proteolytic enzyme, caspase-1. Inflammasome activation leads to caspase-1 activation and promotes functional maturation of IL-1β and IL-18, two prototypical inflammatory cytokines. Besides, inflammasome activation leads to pyroptosis, an inflammatory type of cell death. Inflammasomes are vital for the host to cope with foreign pathogens or tissue damage. Herein, we show that quantum-dot-based iron oxide nanoparticles, MNP@QD, trigger NLRP3 inflammasome activation and subsequent release of proinflammatory interleukin IL-1β by murine bone marrow-derived dendritic cells (BMDCs). This activation is more pronounced if these cells endocytose the nanoparticles before receiving inflammatory stimulation. MNP@QD was characterized by using imaging techniques like transmission electron microscopy, fluorescence microscopy, and atomic force microscopy, as well as physical and spectroscopical techniques such as fluorescence spectroscopy and powder diffraction. These findings may open the possibility of using the composite MNP@QD as both an imaging and a therapeutic tool.

Abstract
The shock ignition (SI) approach to inertial confinement fusion is a promising scheme for achieving energy production by nuclear fusion. SI relies on using a high intensity laser pulse (≈1016 W/cm2, with a duration of several hundred ps) at the end of the fuel compression stage. However, during laser-plasma interaction (LPI), several parametric instabilities, such as stimulated Raman scattering and two plasmon decay, nonlinearly generate hot electrons (HEs). The whole behavior of HE under SI conditions, including their generation, transport, and final absorption, is still unclear and needs further experimental investigation. This paper focuses on the development of an experimental platform for SI-related experiments, which simultaneously makes use of multiple diagnostics to characterize LPI and HE generation, transport, and energy deposition. Such diagnostics include optical spectrometers, streaked optical shadowgraph, an x-ray pinhole camera, a two-dimensional x-ray imager, a Cu Kα line spectrometer, two hot-electron spectrometers, a hard x-ray (bremsstrahlung) detector, and a streaked optical pyrometer. Diagnostics successfully operated simultaneously in single-shot mode, revealing the features of HEs under SI-relevant conditions.

Abstract
Single-spin qubits in semiconductor quantum dots hold promise for universal quantum computation with demonstrations of a high single-qubit gate fidelity above 99.9% and two-qubit gates in conjunction with a long coherence time. However, initialization and readout of a qubit is orders of magnitude slower than control, which is detrimental for implementing measurement-based protocols such as error-correcting codes. In contrast, a singlet-triplet qubit, encoded in a two-spin subspace, has the virtue of fast readout with high fidelity. Here, we present a hybrid system which benefits from the different advantages of these two distinct spin-qubit implementations. A quantum interface between the two codes is realized by electrically tunable inter-qubit exchange coupling. We demonstrate a controlled-phase gate that acts within 5.5 ns, much faster than the measured dephasing time of 211 ns. The presented hybrid architecture will be useful to settle remaining key problems with building scalable spin-based quantum computers. The race to produce a quantum computer has driven the development of many different qubit designs with different benefits and drawbacks. Noiri et al. demonstrate a hybrid device with two coupled semiconductor spin qubits of different designs, which should allow each qubit’s advantages to be exploited.

Abstract
AIM Sessile serrated adenomas/polyps (SSA/Ps) have been proposed as precursors of colorectal cancer. The aims of this investigation were to compare the endoscopic findings of SSA/Ps with those of other serrated lesions and to compare the histological findings of SSA/Ps with those of conventional adenomas. METHOD We retrospectively reviewed colonoscopy records at our institution from 1984 to 2013 and identified cases of endoscopically or surgically resected conventional adenomas and serrated lesions, including SSA/Ps, hyperplastic polyps (HPs) and traditional serrated adenomas (TSAs). The colonoscopic findings of SSA/Ps were compared with those of the other two serrated lesions and histological findings were compared among all groups of lesions. RESULTS There were 79 HPs in 68 patients, 77 SSA/Ps in 63 patients, 167 TSAs in 145 patients and 6324 conventional adenomas in 4129 patients. The inverted type and flat-elevated type were more frequent among SSA/Ps than among the other two types of serrated lesions. Magnifying colonoscopy revealed that a round and open pit pattern, expanded crypt openings and varicose microvascular vessels were more frequently observed among SSA/Ps than among the other types. The incidence of high-grade dysplasia or carcinoma among SSA/Ps (13.0%) was significantly higher than that among HPs (0%, P < 0.001) and equivalent to that among conventional adenomas (12.3%). CONCLUSION SSA/Ps have colonoscopic features distinct from those of HPs and TSAs. The malignant potential of SSA/Ps seems to be equal to that of conventional adenomas.

Abstract
A new piston-cylinder pressure cell for electron spin resonance (ESR) has been developed. The pressure cell consists of a double-layer hybrid-type cylinder with internal components made of the ZrO2-based ceramics. It can generate a pressure of 2 GPa repeatedly and reaches a maximum pressure of around 2.5 GPa. A high-pressure ESR system using a cryogen-free superconducting magnet up 10T has also been developed for this hybrid-type pressure cell. The frequency region is from 50 GHz to 400 GHz. This is the first time a pressure above 2 GPa has been achieved in multi-frequency ESR system using a piston-cylinder pressure cell. We demonstrate its potential by showing the results of the high-pressure ESR of the S=1 system with the single ion anisotropy NiSnCl6·6H2O and the S=1/2 quantum spin system CsCuCl3. We performed ESR measurements of these systems above 2 GPa successfully.

Abstract
Isolated or nonsyndromic tooth agenesis or hypodontia is the most common human malformation. It has been associated with mutations in MSX1, PAX9, EDA, AXIN2, EDAR, EDARADD, and WNT10A. GREMLIN 2 (GREM2) is a strong bone morphogenetic protein (BMP) antagonist that is known to regulate BMPs in embryogenesis and tissue development. Bmp4 has been shown to have a role in tooth development. Grem2(-/-) mice have small, malformed maxillary and mandibular incisors, indicating that Grem2 has important roles in normal tooth development. Here, we demonstrate for the first time that GREM2 mutations are associated with human malformations, which include isolated tooth agenesis, microdontia, short tooth roots, taurodontism, sparse and slow-growing hair, and dry and itchy skin. We sequenced WNT10A, WNT10B, MSX1, EDA, EDAR, EDARADD, AXIN2, and PAX9 in all 7 patients to rule out the effects of other ectodermal dysplasias and other tooth-related genes and did not find mutations in any of them. GREM2 mutations exhibit variable expressivity even within the same families. The inheritance is autosomal dominant with incomplete penetrance. The expression of Grem2 during the early development of mouse teeth and hair follicles and the evaluation of the likely effects of the mutations on the protein structure substantiate these new findings.

Abstract
To investigate the parathyroid function in diabetes mellitus, we performed an oral phosphate load in 6 diabetic patients and 6 nondiabetic subjects without renal failure (serum creatinine less than 1.5 mg/dl). Each subject received a total of 2.0 g of phosphate daily per os on 5 consecutive days. Blood and urine samples were obtained daily before and 2 h after the administration of phosphate in the morning. All subjects responded with a similar increase in the serum phosphorus concentration and fall in the ionized calcium concentration. Intact parathyroid hormone levels rose by 2.6-fold in the control subjects but by less than 1.5-fold in the diabetic subjects. It was concluded that hyporesponsiveness of the parathyroid hormone to phosphate administration was found in the diabetic patients without renal failure.

Abstract
The origin of free amino acids and/or their metabolites of the stratum corneum was investigated by pulse-chase experiments using hairless mice. Two, 24, 48, and 72 hrs after the animals were pulse-chased with 3H-histidine or 3H-arginine, radioactivity was determined in the following three fractions of the epidermis: the 0.1 N HClO4 soluble, ethanol soluble fraction (Fr. I); the 0.1N NClO4 soluble, ethanol insoluble fraction (Fr. II); and the 0.1 N HClO4 insoluble, 8M urea soluble fraction (Fr. III). Radioactivity of the epidermal proteins was also determined in SDS-PAGE gels by the gel slicing method. At first, 3H-histidine and/or 3H-arginine were predominantly incorporated into Fr. III, especially into a certain epidermal protein which showed little mobility on SDS-PAGE. Subsequently, 3H, once incorporated into Fr. III, appeared to shift from Fr. III to Fr. II and, simultaneously, from the top band(s) to a band of 32,000 daltons. As a result of amino acid analysis, a protein of Fr. II was considered a histidine-rich protein corresponding to HRP-II of the new born rats of Ball et al. After 48 hrs, as the radioactivities of Fr. III and Fr. II decreased remarkably, Fr. I gradually increased in radioactivity. The major radioactive substances in Fr. I at 72 hrs were identified as 3H-histidine and 3H-urocanic acid when 3H-histidine was used as a tracer, and as 3H-arginine, 3H-ornithine, and 3H-citrulline in the case of 3H-arginine. The amino acid composition of the histidine-rich protein was very similar to that of the free amino acids of the stratum corneum in the hairless mouse, in which some amino acid metabolites were considered as their precursor amino acids. These results strongly suggest that the free amino acids and/or their metabolites of the stratum corneum might be the final products of a degradation of the histidine-rich protein.

Abstract
Nuclear factor kappa B (NF-κB) signaling plays critical roles in many physiological and pathological processes, including regulating organogenesis. Down-regulation of NF-κB signaling during development results in hypohidrotic ectodermal dysplasia. The roles of NF-κB signaling in tooth development, however, are not fully understood. We examined mice overexpressing IKKβ, an essential component of the NF-κB pathway, under keratin 5 promoter (K5-Ikkβ). K5-Ikkβ mice showed supernumerary incisors whose formation was accompanied by up-regulation of canonical Wnt signaling. Apoptosis that is normally observed in wild-type incisor epithelium was reduced in K5-Ikkβ mice. The supernumerary incisors in K5-Ikkβ mice were found to phenocopy extra incisors in mice with mutations of Wnt inhibitor, Wise. Excess NF-κB activity thus induces an ectopic odontogenesis program that is usually suppressed under physiological conditions.

Abstract
BACKGROUND AND PURPOSE Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with no effective treatment. Fasudil hydrochloride (fasudil), a potent rho kinase (ROCK) inhibitor, is useful for the treatment of ischaemic diseases. In previous reports, fasudil improved pathology in mouse models of Alzheimer's disease and spinal muscular atrophy, but there is no evidence in that it can affect ALS. We therefore investigated its effects on experimental models of ALS. EXPERIMENTAL APPROACH In mice motor neuron (NSC34) cells, the neuroprotective effect of hydroxyfasudil (M3), an active metabolite of fasudil, and its mechanism were evaluated. Moreover, the effects of fasudil, 30 and 100 mg·kg(-1), administered via drinking water to mutant superoxide dismutase 1 (SOD1(G93A)) mice were tested by measuring motor performance, survival time and histological changes, and its mechanism investigated. KEY RESULTS M3 prevented motor neuron cell death induced by SOD1(G93A). Furthermore, M3 suppressed both the increase in ROCK activity and phosphorylated phosphatase and tensin homologue deleted on chromosome 10 (PTEN), and the reduction in phosphorylated Akt induced by SOD1(G93A). These effects of M3 were attenuated by treatment with a PI3K inhibitor (LY294002). Moreover, fasudil slowed disease progression, increased survival time and reduced motor neuron loss, in SOD1(G93A) mice. Fasudil also attenuated the increase in ROCK activity and PTEN, and the reduction in Akt in SOD1(G93A) mice. CONCLUSIONS AND IMPLICATIONS These findings indicate that fasudil may be effective at suppressing motor neuron degeneration and symptom progression in ALS. Hence, fasudil may have potential as a therapeutic agent for ALS treatment.

Abstract
Abstract
Background: Based on the results of a case-control study performed in Japan (Okayama and Kagawa), it was revealed that gene polymorphisms of the estrogen receptor (single nucleotide polymorphisms, SNPs), ESR1/6q25.1-rs2046210 and rs3757318, were closely related to breast cancer risk in Japanese women, and that the odds ratios per allele of individual SNPs were 1.37 [95% CI: 1.1 - 1.7] and 1.33 [1.04 - 1.7], respectively (San Antonio Breast Cancer Symposium 2012, Mizoo et al.). To examine the effects of these SNPs on the pathogenic mechanism of breast cancer, we analyzed the relationship of SNPs with reproductive/physiological factors (age of menarche and number of births), physical factors (height and Body Mass Index [BMI]), family history and mammographic breast density.
Methods: Among the patients enrolled in the case-control study, the patients who could be evaluated regarding their lifestyle, SNPs and mammographic breast density were divided into the case group (N = 394) and the control group (N = 511) as the dataset for the study. SNPs were analyzed using the TaqMan genotyping assay® for blood samples. In the analysis of the relationship between SNPs and breast cancer risk, the odds ratios (OR) and 95% confidence intervals (95%CI) were calculated using logistic regression analysis. For the analysis of the relationship between SNPs and the factors, t-test and chi-square test were used.
Results: In our dataset, the age-adjusted OR [95% CI] of ESR1/6q25.1-rs2046210 and rs3757318 were 2.22 [1.41 - 3.55] (AA vs. GG) and 2.12 [1.2 - 3.8] (AA vs. GG), respectively, suggesting that they would be significant risk factors. As a result of analyzing the relationship between SNPs and other factors, a significantly lower BMI was observed for the risk allele AA/AG of rs2046210, compared to GG (p = 0.014, t-test). Regarding the mammographic breast density, a significantly higher proportion of mammary glands with high density was confirmed for the risk allele AA/AG of rs2046210, compared to GG (p = 0.0389, chi-square test). The tendency towards a high mammographic breast density in the rs2046210 risk allele AA/AG was also confirmed based upon a stratified analysis of the case and control groups before and after menopause, and a significant correlation was observed, especially before menopause (p = 0.026, chi-square test).
Conclusion: Mammographic high breast density is generally considered as one of the breast cancer risks, and it was suggested that gene polymorphisms of ESR1/6q25.1-rs2046210 might affect mammographic breast density.

Abstract
[Background] Based on the results of a case-control study performed in Japan (Okayama and Kagawa), it was revealed that gene polymorphisms of the estrogen receptor (single nucleotide polymorphisms, SNPs), ESR1/6q25.1-rs2046210 and SNPs of rs3757318 were closely related to breast cancer risk in Japanese women, and that the odds ratio per allele of individual SNPs were 1.37 [95% CI: 1.1 - 1.7] and 1.33 [1.04 - 1.7], respectively (San Antonio Breast Cancer Symposium 2012, Mizoo et al.). We analyzed the relationship of ESR1/6q25.1-rs2046210 and rs3757318 SNPs with the clinical characteristics of breast cancer patients.
[Methods] Among the patients enrolled in the case-control study, 508 breast cancer patients who underwent genotyping for ESR1/6q25.1-rs2046210 and rs3757318 were analyzed as the subjects. SNPs were analyzed using the TaqMan genotyping assay® for blood samples. To analyze the relationship of genotypes (AA/GG, GG) with age at diagnosis, height, weight, BMI, age of menarche, birth history, pathological degree of progression and estrogen receptor, t-test and chi-square test were used.
[Results] The genotypes of rs2046210 are AA (12%), AG (41%) and GG (46%), and the patients with the risk allele (AA/AG) had significantly higher height (p = 0.0015, t-test) and lower Body Mass Index (BMI) (p = 0.0022, t-test). The genotypes of rs3757318 are AA (8%), AG (39%) and GG (53%), and the patients with the risk allele (AA/AG) were characterized by significantly lower BMI (p = 0.041, t-test), no birth history (p = 0.0473, chi-square) and negative hormone receptor (p = 0.0128, chi-square). Overall, tendencies related to increased height, lower BMI and negative estrogen receptor were confirmed for the risk alleles of rs2046210 and rs3757318.
[Conclusion] It was suggested that SNPs of rs2046210 and rs3757318 might be related to the development of estrogen-receptor-negative breast cancer.

Abstract
OBJECTIVE Periodontitis is a chronic inflammatory disease of the tissues supporting the teeth and is caused by subgingival plaque. Systemic increases in reactive oxygen species are involved in pathogenesis of periodontitis. This study addressed the relationship between levels of serum oxidative stress and antibodies against putative periodontopathic bacteria and their association with periodontal conditions, in a community-based study. SUBJECTS AND METHODS Serum samples were measured for reactive oxygen metabolite (ROM) levels and anti-oxidant capacity. The serum levels of immunoglobulin G (IgG) antibodies to Porphyromonas gingivalis (Pg), Prevotella intermedia (Pi), Aggregatibacter actinomycetemcomitans (Aa), and Eikenella corrodens (Ec) were determined by ELISA. RESULTS The participants with greater clinical attachment loss had higher serum ROM levels and IgG antibody titers to Pg. Serum ROM levels were positively correlated with antibody titers to Pg, Pi, and Ec. When the participants with greater probing pocket depth and clinical attachment loss were used as the dependent variables, high ROM levels showed a statistically significant associations in multivariate logistic analyses; the adjusted odds ratios were 2.9 (95% confidence interval = 1.0-8.5) and 6.0 (95% confidence interval = 2.0-17.6), respectively. CONCLUSIONS It was concluded that an increased oxidative stress may be detrimental to periodontitis in Japanese community-dwelling adults.

Abstract
Abstract
[Background] Lifestyle, including diet and physical activity, and birth/breastfeeding history are known to affect the risk for breast cancer. A correlation between single nucleotide polymorphisms (SNPs) and breast cancer risk has also been suggested in some reports, but the gene-environment interaction with breast cancer risk has not been examined widely.
[Methods] The subjects were 476 breast cancer patients and 528 controls who attended a health check and had no history of breast cancer. Lifestyle was examined using a questionnaire with 48 questions about diet, physical activity, smoking habits, alcohol intake, and birth/breastfeeding history, etc. Based on past reports, we analyzed 6 SNPs (TNRC9-rs3803662, LSP1/11q-rs3817198, MAP3K1-rs889312, 8q24-rs13281615, 5p12-rs981782, and TGFβ1-rs1800470) using blood samples, and calculated age-adjusted odds ratios in a multiple logistic regression analysis.
[Results] The study was performed from December 2010 to November 2011. Lifestyle factors (age-adjusted odds ratio, [95% confident interval]) found to have a significant correlation with development of breast cancer included BMI (1.041, [1.00–1.08]), smoking history (2.28, [1.45–3.65]), small number of births (1.18, [1.05–1.34]), no exercise during leisure time (1.36, [1.06–1.77]), low intake of green and yellow vegetables (1.69, [1.01–2.85]), and low intake of mushrooms (1.58, [1.05–2.39]). Stratified analysis based on menopause status showed that smoking history (1.85, [1.00–3.49]) and low intake of green and yellow vegetables (2.5, [1.03–5.88]) were significant risk factors before menopause, and that smoking history (2.28, [1.45–3.65]), low intake of green and yellow vegetables (2.24, [1.09–4.68]), no exercise during leisure time (1.67, [1.19–2.36]), small number of births (1.49, [1.25–1.78]), and no breastfeeding history (1.03, [1.01–1.06]) were significant risk factors after menopause. The results of SNP analysis suggested that TNRC9-rs3803662 was a significant risk factor in women before menopause (2.29, [1.25–4.25]). However, in multivariate analysis including lifestyle factors and SNPs, only smoking history emerged as a significant risk factor in women before menopause.
[Conclusion] A correlation between lifestyle and breast cancer risk was found in this study, consistent with previous findings. Lifestyle and environmental factors such as births and breastfeeding may be more important than SNPs as risk factors for breast cancer.

Abstract
The oral mucosa plays critical roles in protection, sensation, and secretion and can be classified into masticatory, lining, and specialized mucosa that are known to be functionally, histologically, and clinically distinct. Each type of oral mucosa is believed to develop through discrete molecular mechanisms, which remain unclear. MicroRNAs (miRNAs) are 19 to 25nt non-coding small single-stranded RNAs that negatively regulate gene expression by binding target mRNAs. miRNAs are crucial for fine-tuning of molecular mechanisms. To investigate the role of miRNAs in oral mucosa development, we examined mice with mesenchymal (Wnt1Cre;Dicer(fl/fl)) conditional deletion of Dicer. Wnt1Cre;Dicer(fl/fl) mice showed trans-differentiation of lining mucosa into an epithelium with masticatory mucosa/ skin-specific characteristics. Up-regulation of Fgf signaling was found in mutant lining mucosal epithelium that was accompanied by an increase in Fgf7 expression in mutant mesenchyme. Mesenchyme miRNAs thus have an indirect effect on lining mucosal epithelial cell growth/differentiation.
