Abstract
OBJECTIVES Creatinine (Cr) as a marker of renal function has limited value in amyotrophic lateral sclerosis (ALS) because patients with ALS have reduced muscle mass. Thus, there is a need for alternative methods of assessing renal function. Cystatin C (CysC), which is unaffected by muscle mass, is potentially an ideal biomarker of nephrotoxicity in ALS; however, its utility requires validation. MATERIAL AND METHODS One hundred and six subjects were recruited for the study: 76 ALS patients and 30 healthy controls. We compared the Cr-based estimated glomerular filtration rate (eGFR) with the CysC-based eGFR in the ALS patients and healthy controls. The results were further analysed according to the severity of ALS in the patients. RESULTS The mean Cr-based eGFRs were 257.2 ± 383.1 ml/min/1.73 m(2) in the ALS group and 98.1 ± 34.9 in the control group; however, the mean CysC-based eGFRs were not significantly different between both groups. Thus, the Cr-based eGFR in the ALS group was markedly higher than any of the other values. Although serum CysC levels did not correlate with the severity of ALS according to the ALS Functional Rating Scale-Revised, strong simple correlations were observed between serum Cr levels and the severity of ALS (correlation coefficient = 0.734, P < 0.001). CONCLUSIONS This study demonstrates the potential usefulness of CysC as a biomarker of renal function in ALS patients. Furthermore, its applicability could be extended to other neuromuscular diseases.

Abstract
UNLABELLED Assessments of serum 25-hydroxyvitamin D levels in 1,683 Japanese from a population-based cohort revealed prevalences of vitamin D insufficiency and deficiency were 81.3 and 1.2%, respectively. Vitamin D deficiency was significantly associated with female sex, examined month, current smoking, lack of regular walking, higher intact parathyroid hormone (iPTH), and poor daily vitamin D intake. INTRODUCTION To clarify the characteristics of subjects with vitamin D insufficiency and deficiency among men and women in the general Japanese population. METHODS We initiated research on osteoarthritis/osteoporosis against disability (ROAD), a large-scale population-based cohort study, in 2005-2007. Blood examination was performed to measure serum 25-hydroxyvitamin D (25D) and iPTH levels and biochemical markers of bone turnover in 1,683 participants (595 men, 1,088 women). Participants completed an interviewer-administered questionnaire, measurements of bone mineral density, and x-ray examination. Vitamin D deficiency and insufficiency were defined by serum 25D levels <10 and ≥10 but <30 ng/mL, respectively. RESULTS The prevalence of vitamin D insufficiency and deficiency was 81.3 and 1.2%, respectively. Multinominal logistic regression analyses using potentially confounding variables revealed vitamin D insufficiency was significantly associated with age (+1 year, relative risk ratio, 0.98; 95% confidence interval, 0.96-0.99), gender (women vs. men, 2.28; 1.59-3.30), residing areas (coastal area vs. mountainous area, 0.58; 0.41-0.81), examined month (October, November, December vs. January, 0.51; 0.34-0.76), and serum levels of iPTH (+1 pg/mL, 1.02; 1.01-1.03). Vitamin D deficiency was significantly characterised by female sex (20.5; 3.1-136.7), examined month (0.28; 0.09-0.95), current smoking habit (6.39; 1.78-23.0), lack of regular outside walking (3.96; 1.34-11.7), higher iPTH (1.02; 1.01-1.03) and poor daily vitamin D intake (+10 μg/day, 0.48; 0.24-0.93). CONCLUSIONS A high prevalence of vitamin D insufficiency and a low prevalence of vitamin D deficiency were found in Japanese men and women, and the characteristics of vitamin D status were clarified.

Abstract
Oxidative stress is associated with age-related reactions. The anti-oxidative effects of a reduced form of co-enzyme Q10 (rCoQ10) suppress oxidative stress, which may contribute to the prevention of age-related inflammatory reactions. We examined the effects of topically applied rCoQ10 on periodontal inflammatory reactions in a rat aging model. Male Fischer 344 rats, 2 (n = 6) and 4 mos (n = 18) of age, were used. All of the two-month-old rats and 6 of the four-month-old rats were sacrificed and 12 remaining four-month-old rats received topically applied ointment with or without 1% rCoQ10 on the gingival surface until they reached 6 mos of age. The rats showed an age-dependent increase in circulating oxidative stress. RCoQ10 decreased oxidative DNA damage and tartrate-resistant acid-phosphatase-positive osteoclasts in the periodontal tissue at 6 mos of age as compared with the control. The same conditions lowered gene expression of caspase-1 and interleukin-1β in the periodontal tissue. Furthermore, Nod-like receptor protein 3 inflammasomes were less activated in periodontal tissues from rCoQ10-treated rats as compared with the control rats. Our results suggest that rCoQ10 suppresses age-related inflammatory reactions and osteoclast differentiation by inhibiting oxidative stress.

Abstract
Vascular calcification, especially medial artery calcification, is associated with increased morbidity and mortality in patients with diabetes mellitus and end-stage kidney disease. Advanced glycation end products (AGEs) accumulated in these patients may be associated with vascular calcification, although their actions are obscure. Since AGEs can induce oxidative stress, which leads to vascular damage, we investigated an in vitro study to elucidate the effects of AGEs and the roles of NAD(P)H oxidase in the pathogenesis of vascular calcification. A7r5, rat vascular smooth muscle cells (VSMCs) were incubated in calcification medium with glycolaldehyde-derived AGE (AGE3) to measure calcium deposition and 8-hydroxydeoxyguanosine (8-OHdG) and to determine mRNA levels of osteopontin (OPN), osteocalcin (OCN), Runx2, Nox-1, Nox-4, and p22(phox) by real-time PCR. Calcium deposition was increased by AGE3 in a dose-dependent manner (100-300 μg/dl) in A7r5 cells. Expression levels of Runx2, OPN, and OCN mRNAs were significantly higher in AGE3 treatment than those in control BSA. Increased 8-OHdG concentration in the culture medium and higher expression of Nox-1, Nox-4, and p22(phox) mRNAs (3-6-fold) were observed in cells treated with AGE3. AGE3-stimulated calcium deposition was significantly decreased in the cells transfected by either small interfering RNA for Nox-4 or p22(phox), compared to the controls. In contrast, no significant effect was shown in silencing of Nox-1. Excessive oxidative stress and osteoblastic transition of VSMCs are involved in the pathogenesis of AGEs-induced vascular calcification. NAD(P)H oxidase plays important roles in this process.

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
BACKGROUND Recently, mutations in the TARDBP gene encoding the TAR DNA-binding protein 43 (TDP-43) have been identified in some familial amyotrophic lateral sclerosis (ALS) and sporadic ALS patients. The phenotype and frequency of TARDBP mutation carriers reportedly varies greatly among European populations. OBJECTIVE To define the phenotypic spectrum of TARDBP mutations and their frequency in a Swiss population. METHODS A total of 225 patients diagnosed with ALS (182 sporadic cases, 43 familial cases) were screened for TARDBP mutations. All patients were carefully examined and interviewed for a familial predisposition. Except for 1 patient who was followed at the University of Geneva, all patients were followed at the Kantonsspital St. Gallen. RESULTS 43 patients (19.5%) had a definite family history for ALS. A TARDBP mutation was identified in 4 of these (9.3%). Two female ALS patients carried the p.Asn352Ser mutation. Both had limb onset and a slowly progressive course of the disease. A novel mutation (p.Gly376Asp) was identified in a 44-year-old female patient. Survival amongst affected family members varied between 6 and 18 months. The patient and also the other siblings affected with ALS had an accessory nipple. A fourth male patient carried the p.Ala90Val mutation. None of the patients had overt cognitive impairment. TARDBP mutations were not found among patients with sporadic forms of ALS. CONCLUSION In this Swiss population, the frequency of familial ALS is higher than reported earlier in other populations. The novel p.Gly376Asp TARDBP mutation is associated with rapid disease progression and may be associated with an accessory nipple while the p.Asn352Ser mutation is associated with slow disease progression.

Abstract
Replacing the thoracic esophagus with the colon is one mode of reconstruction after esophagectomy for esophageal cancer. There is, however, a high incidence of postoperative necrosis of the transposed colon. This study evaluated the outcomes of colon interposition with the routine use of superdrainage by microvascular surgery. Twenty-one patients underwent colon interposition from 2004 to 2009. The strategy for colon interposition was to: (i) use the right hemicolon; (ii) reconstruct via the subcutaneous route; (iii) perform a microvascular venous anastomosis for all patients; and (iv) perform a microvascular arterial anastomosis when the arterial blood flow was insufficient. The clinicopathologic features, surgical findings, and outcomes were investigated. The colon was used because of a previous gastrectomy in 18 patients (85.7%) and synchronous gastric cancer in three patients (14.3%). Eight patients (38.1%) underwent preoperative chemoradiotherapy including three (14.3%) treated with definitive chemoradiotherapy. Seven patients (33.3%) underwent microvascular arterial anastomosis to supplement the right colon blood supply. Pneumonia occurred in four patients (19.0%). Anastomotic leakage was observed in five patients (23.8%); however, no colon necrosis was observed. The 3-year and 5-year overall survival rates were both 50.6%. Colon interposition with superdrainage results in successful treatment outcomes. This technique is one option for colon interposition employing the right hemicolon.

Abstract
Peroxisomes are involved in a variety of metabolic processes, including β-oxidation of fatty acids, especially very long chain fatty acids. Three peroxisomal ABC proteins belonging to subfamily D have been identified in mammalian peroxisomes that have an important role in fatty acid metabolism. ABCD1/ALDP and ABCD2/ALDRP are suggested to be involved in the transport of very long chain acyl-CoA, and ABCD3/PMP70 is involved in the transport of long chain acyl-CoA. ABCD1 is known to be responsible for X-linked adrenoleukodystrophy (X-ALD); an inborn error of peroxisomal β-oxidation of very long chain fatty acids. X-ALD is characterized biochemically by the accumulation of very long chain fatty acids in all tissues, including the brain white matter. Progressive demyelination of the central nervous system and adrenal dysfunction have been observed. The pharmacological up-regulation of peroxisomal β-oxidation of very long chain fatty acids and the suppression of fatty acid elongation are important aspects of an optimal therapeutic approach. Attractive targets for the treatment of X-ALD patients include the ABCD2 as well as elongase that is involved in the elongation of very long chain fatty acids. In addition, stabilization of mutant ABCD1 that has retained some of its function might be another approach, since most of the mutant ABCD1s with a missense mutation are degraded rapidly by proteasomes before or after targeting to peroxisomes. Protection of the central nervous system against oxidative damage is also important in order to delay the progress of disease. We summarize recent pharmaceutical studies and consider the potential for future X-ALD therapies.

Abstract
The objective of this article is to describe the capability of a two-dimensional (2D) approach to X-ray absorption near-edge structure (XANES) measurement by means of a partial fluorescence yield (PFY) method. 2D-XANES measurements were achieved by using a silicon drift detector as an energy-dispersive fluorescence detector. The advantage of this technique is that it allows full surveys of X-ray fluorescence data that are lost in conventional PFY measurements. The availability of a map approach was demonstrated by applying it to XANES measurements in both a diluted (Mn-doped nano-diamond) and a concentrated (MnO crystal) manganese sample. The 2D approach clearly distinguished between the PFY spectra of Mn and O atoms, where absorption edges of both elements are close to each other. Further, the 2D approach extracted an unambiguous PFY spectrum of phosphorus in the XANES measurement of SS304 (P < 0.045 wt%).

Abstract
BACKGROUND It has been suggested that oral organisms in children are mainly those transmitted from their mothers. That may account for the relationship between caries levels in children and their parents. However, few studies have investigated the effect of trying to prevent vertical transmission of oral organisms on dental caries levels in children, and the findings in the studies are controversial. The aim of this study was to investigate the association between measures to prevent vertical transmission of oral organisms and the caries experience in 3-year-old children. METHODS Data were collected from dental examinations for 3-year-old children and a self-administered questionnaire for their caregivers. Absence of maternal sharing of utensils and mouth-to-mouth feeding between caregivers and children was used as the variable about behaviour to prevent vertical transmission of oral organisms. Sex, age in months, dietary behaviour, oral health behaviour and sociodemographic factors were used as covariates. RESULTS AND CONCLUSION Data for 3,035 children (73.5% of the subjects) were analysed. Caregivers who practised vertical transmission prevention tended to have better oral health behaviours. Multivariate logistic regression analysis did not show any significant association between behaviour to prevent vertical transmission and caries experience (OR = 1.10, 95% CI = 0.86-1.41). This study suggests that caregiver behaviour to prevent vertical transmission was not effective in reducing levels of childhood caries.

Abstract
OBJECTIVE The aim of this study was to clarify the characteristic imaging features that can be used to differentiate ameloblastomas from keratocystic odontogenic tumours and to examine the significant imaging features contributing to a correct diagnosis. METHODS 60 observers (39 specialists in oral and maxillofacial radiology and 21 non-specialists) examined CT and/or panoramic images of 10 ameloblastomas and 10 keratocystic odontogenic tumours shown on a webpage and made diagnoses. Their correct answer ratios were then calculated. The imaging features of the tumours were evaluated and expressed as binary numbers or quantitative values. The imaging features that contributed to a correct diagnosis were elucidated using logistic regression analysis. RESULTS The mean correct answer ratio was 61.3% ± 17.2% for the diagnosis of ameloblastomas and keratocystic odontogenic tumours. CT images produced higher correct answer ratios for diagnosis of keratocystic odontogenic tumours by specialists. The significantly different imaging features between ameloblastomas and keratocystic odontogenic tumours were the degree of bone expansion and the presence of high-density areas. The significant imaging features contributing to a correct imaging diagnosis were the number of locules, the presence of high-density areas and the inclusion of impacted teeth. CONCLUSION The presence of high-density areas is the most useful feature in the differential diagnosis of ameloblastomas and keratocystic odontogenic tumours based on comparison of the imaging features of both tumours and examination of the diagnostic contributions of these features.
