The authors evaluate indoor air quality in apartments built according to the South Korean Clean-Healthy House construction standard. The evaluation includes three types of residential units with differing gross floor areas. Indoor air was analyzed for formaldehyde (observed range 52.0–99.2 ug/m3), acetaldehyde (14.6–61.0 ug/m3), benzene (0.6–1.3 ug/m3), toluene (161.8–371.0 ug/m3) ethylbenzene (6.5–17.0 ug/m3), xylene (14.7–45.0 ug/m3), and styrene (37.7–112.5 ug/m3). The concentrations of all analyzed substances were within the South Korean guidelines. The findings confirm that the Clean-Healthy Homes initiative has led to a greatly improved indoor air environment compared to existing newly built apartment blocks in South Korea. However, this construction standard is applied only to large apartment developments comprising 1,000 or more units, and it seems that further effort should be made to extend the standard to stand-alone residences and small-scale apartment blocks in order to ensure that indoor air quality is maintained more widely.

PVC floor material is widely used in Korean homes, and people customarily sit or lie on the floor surface. This could potentially put residents of such homes at high risk of exposure to semi-volatile organic compounds (SVOCs). However, there is a current lack of information regarding the degree of SVOC contamination in Korean homes. Therefore, this study was implemented to measure SVOC concentration in the air and house dust in homes and kindergartens, places where children spend long periods of time. The substances analyzed were 2E1H, D6, DEP, TBP, TCEP, DBP, TPP, DOA, and DEHP. Amounts of 2E1H, D6, DEP, DBP, and DEHP were detected in the air of the homes included in the study, and the average air concentrations of DBP and DEHP were 0.53 μg/m3 and 0.28 μg/m3, respectively. The average dust DEHP concentrations in the rooms of homes and kindergartens were 2,800 μg/g and 4,350 μg/g, respectively, showing that higher values were measured in kindergartens. The measured DEHP concentrations in the dust of both homes and kindergartens where PVC floor materials are used were high.

Wide-ranging varieties and/or strains of bulb onions (Allium cepa Common onion group) and shallots (A. cepa Aggregatum group) were utilized to understand the variation in chemical compounds responsible for their taste. The bulb samples of 10 F1 commercial onion varieties (seven short-day and three long-day varieties) from Japan and 12 shallot landraces from abroad (Vietnam: three landraces; Indonesia: nine landraces) were collected as plant materials once a year in 2014 and 2015. The contents of S-alk(en)yl-L-cysteine sulfoxides, total flavonoids, and soluble sugars—including fructose, glucose, sucrose, and fructans—were determined to find differences between bulb onions and shallots, as well as to detect variations among varieties and/or landraces. While a principal component analysis (PCA) based on the results from both 2014 and 2015 could clearly discriminate shallots from bulb onions from a phytochemical perspective, bulb onions mainly had higher monosaccharides than shallots. By contrast, shallots produced more disaccharides than bulb onions. In most cases, regression analyses using the numerical data of the chemical compounds found in bulb onions and shallots suggested year-year correlations between 2014 and 2015. The flavonoid and PeCSO (S-(1-propenyl)-L-cysteine sulfoxide: isoalliin) contents in shallots were higher than those detected in bulb onions, which indicated the stronger pungent and bitter taste could be attributable to excess amounts of these compounds in this tropical plant.

Recently biometric authentication systems have become open and large scale thus leading to its widespread use. However, no systematic study has been done with regards to the safety of such systems. On the other hand, cancelable biometrics, the intentional distortion of biometric characteristics to protect sensitive data in biometric authentication systems, has been widely studied. Many methods have been proposed for cancelable biometrics technology, but the security criterion in such is indefinite. In this paper, we consider cancelable biometric techniques from the perspective of the safety of the system. We also verify the effect of the security precaution of the liveness detection techniques using Fault Tree Analysis, a risk evaluation method about data protection and spoofing prevention techniques.

Non-neuronal and atropine-sensitive ileal contractile responses to short chain fatty acids (SCFAs) are detected in the neonatal stage, and change with age or inflammatory conditions. However, the roles of luminal SCFAs in developmental changes have not yet been elucidated. We examined ileal contractile responses to SCFAs in mice colonized with different SCFA-producing intestinal microbiota under normal and inflammatory conditions. Using conventional (Conv), germ-free (GF), and gnotobiotic mice infected with Bifidobacterium (GB-bif), Propionibacterium (GB-prop), or Lactobacillus (GB-lact), ileal contractions were measured in 1-day-old neonates and 7-week-old mice using an isotonic transducer. Contractions occurred in all 1-day-old neonates, and were significantly desensitized in the adult stage in the Conv, GB-bif, and GB-prop groups, but not in the GF and GB-lact groups. An injection of lipopolysaccharide frequently restored desensitized contractions; however, the contraction rate did not change in the GF and GB-lact groups. The relative mRNA expression of a SCFA receptor (GPR43) or nicotinic acetylcholine receptor α7 was weaker in the GF group (0.3-fold or 0.4-fold expression level, respectively) than in the Conv group. In conclusion, the luminal inhabitation of SCFA-producing bacteria may potentiate the regulation of non-neuronal and atropine-sensitive ileal contractile responses to SCFAs under healthy and inflammatory conditions.

Background: Maternal care (egg-nymph guarding behavior) has been recorded in some genera of Acanthosomatidae. However, the origin of the maternal care in the family has remained unclear due to the lack of phylogenetic hypotheses. Another reproductive mode is found in non-caring species whose females smear their eggs before leaving them. They possess pairs of complex organs on the abdominal venter called Pendergrast’s organ (PO) and spread the secretion of this organ onto each egg with their hind legs, which is supposed to provide a protective function against enemies. Some authors claim that the absence of PO may be associated with the presence of maternal care. No study, however, has tested this hypothesis of a correlated evolution between the two traits. Results: We reconstructed the molecular phylogeny of the subfamily Acanthosomatinae using five genetic markers sequenced from 44 species and one subspecies with and without maternal care. Eight additional species from the other two acanthosomatid subfamilies were included as outgroups. Our results indicated that maternal care has evolved independently at least three times within Acanthosomatinae and once in the outgroup species. Statistical tests for correlated evolution showed that the presence of maternal care is significantly correlated with the secondary loss or reduction of PO. Ancestral state reconstruction for the node of Acanthosoma denticaudum (a non-caring species in which egg smearing with developed POs occurs) and A. firmatum (a caring species with reduced POs) suggested egg smearing was still present in their most recent common ancestor and that maternal care in A. firmatum has evolved relatively recently. Conclusions: We showed that maternal care is an apomorphic trait that has arisen multiple times from the presence of PO within the subfamily Acanthosomatinae. The acquisition of maternal care is correlated with the reduction or loss of PO, which suggests an evolutionary trade-off between the two traits resulting from physiological costs. This prediction also implies that presence of maternal care can be highly expected for those groups lacking behavioral data, which invariably also lack the organ. No secondary loss of maternal care was detected in the present tree. We suggest that the loss of maternal care may be suppressed due to the vulnerability of the PO-free condition, which thus maintains maternal care.

Coconut oil has recently attracted considerable attention as a potential Alzheimer’s disease therapy because it contains large amounts of medium-chain fatty acids (MCFAs) and its consumption is thought to stimulate hepatic ketogenesis, supplying an alternative energy source for brains with impaired glucose metabolism. In this study, we first reevaluated the responses of plasma ketone bodies to oral administration of coconut oil to rats. We found that the coconut oil-induced increase in plasma ketone body concentration was negligible and did not significantly differ from that observed after high-oleic sunflower oil administration. In contrast, the administration of coconut oil substantially increased the plasma free fatty acid concentration and lauric acid content, which is the major MCFA in coconut oil. Next, to elucidate whether lauric acid can activate ketogenesis in astrocytes with the capacity to generate ketone bodies from fatty acids, we treated the KT-5 astrocyte cell line with 50 and 100 μM lauric acid for 4 h. The lauric acid treatments increased the total ketone body concentration in the cell culture supernatant to a greater extent than oleic acid, suggesting that lauric acid can directly and potently activate ketogenesis in KT-5 astrocytes. These results suggest that coconut oil intake may improve brain health by directly activating ketogenesis in astrocytes and thereby by providing fuel to neighboring neurons.

Duchenne muscular dystrophy (DMD) is a life-limiting X-linked genetic disorder caused by a lack of the membrane-associated protein dystrophin. The absence of dystrophin increases the susceptibility of muscle fibers to damage. Repeated damage results in ineffective muscle repair and the development of pseudo-hypertrophied muscles; these bulky muscles are weak despite their size. The mechanisms underlying the functional impairments in dystrophic muscle have not yet been fully determined. However, several recent studies indicate that elevated intracellular Ca2+ homeostasis is a cause or facilitator of the development of muscle weakness in DMD. This review focuses on abnormalities of Ca2+ homeostasis and the possibilities for treatment by counteracting the Ca2+ dysregulation.

Twelve distributional patterns of fluorescent body parts, including complete non-fluorescence, were found in diverse taxonomic groups of small hydromedusae (≤21 mm in umbrellar diameter) collected in 2008-2010 in Tanabe Bay and a freshwater pond in Tanabe city, Wakayama Prefecture, Japan, and in Suma harbor, Kobe city, Hyogo Prefecture. Only three of the green fluorescence patterns have been described until now. Particular fluorescence patterns may have originated convergently more than once within this taxonomic group. In Liriope tetraphylla the distribution of fluorescence changes during development, and the eggs of Clytia languida also display fluorescence.

A new method is described for printing nucleotide sequences by assembling square microcells, representing nucleotides, into blocks, and by differentiating micro-cells following a color code, a gray scale, etc., corresponding to the four types of nucleotides. By printing micro-cells, whose sides are close to 250μm, using a laser printer, the complete sequence of a genome of the size close to 1M bases can be printed in the space of full size of A4, without loosing any original information. By enlarging the print using a magnifying glass or a photo-copy machine, the original sequence can be reconstituted, visually or mechanically. Overall and regional characteristics of genomes (e.g. distribution of gene-coding regions) can be analyzed using a plot of this type. The scheme for classifying micro-cells can be modified, in order to present different types of information such as distribution of purines and pyrimidines or that of different types of dinucleotide combinations through the genome.

I construct data on the numbers of workers and suicide victims in their working ages in Japan from 1980 to 2010 for each of 10 occupation classes and for males and females separately. I document a complex transition of the job profiles of occupation classes, and establish a correspondence between Japanese and international job classifications. Four general characteristics of occupation-wise suicide risk in Japan emerge from graphical analyses of constructed data. First, heterogeneous aging patterns of suicide deaths and numbers of workers create complex aging patterns of suicide rates. Second, the age-adjustment and stabilizations of suicide rates are crucial for an accurate measurement and a fair comparison of suicide risk for workers in each occupation or over the entire economy. Third, the surge of overall suicide risk in Japan since 1998 might be driven by that in few occupations for each gender. Particularly, (a) a high suicide-risk profiles for male workers in agricultural, forestry and fishery and jobless categories has been stable over time, hence not a main culprit of such surge, and (b) less informative patterns of female suicide rates may be a consequence of the cancellations of higher suicide risk in some occupations and lower suicide risk in any other occupations during such surge. Fourth, gender- and occupation-wise pattern of suicide risk is further confounded with heterogeneity across regions.

Image analysis is crucial to medical and biological applications. Recent advances in imaging technology have led to the demand for processing and visualizing a large amount of three-dimensional (3D) biomedical images. In addition, cloud computing has become popular for managing big data. Unfortunately, conventional image-processing systems either lack cloud computing services or advanced 3D processing abilities. In this paper, we present a novel cloud-based system for sharing, processing, and visualizing 3D biomedical images. Our system employs a standard web browser as a client interface that interactively communicates with high-performance servers. Thus, an inexpensive tablet PC without an advanced graphics processing unit (GPU) can be used for 3D image processing and visualization. Our system provides the sharing of limited software and hardware resources, and it allows for effective collaboration between researchers. We demonstrate the applicability and functionality of the system by examining typical case studies on biomedical images. We also examine the performance of our system numerically.
