Abstract
BACKGROUND Human health status can be measured on the basis of many different parameters. Statistical relationships among these different health parameters will enable several possible health care applications and an approximation of the current health status of individuals, which will allow for more personalized and preventive health care by informing the potential risks and developing personalized interventions. Furthermore, a better understanding of the modifiable risk factors related to lifestyle, diet, and physical activity will facilitate the design of optimal treatment approaches for individuals. OBJECTIVE This study aims to provide a high-dimensional, cross-sectional data set of comprehensive health care information to construct a combined statistical model as a single joint probability distribution and enable further studies on individual relationships among the multidimensional data obtained. METHODS In this cross-sectional observational study, data were collected from a population of 1000 adult men and women (aged ≥20 years) matching the age ratio of the typical adult Japanese population. Data include biochemical and metabolic profiles from blood, urine, saliva, and oral glucose tolerance tests; bacterial profiles from feces, facial skin, scalp skin, and saliva; messenger RNA, proteome, and metabolite analyses of facial and scalp skin surface lipids; lifestyle surveys and questionnaires; physical, motor, cognitive, and vascular function analyses; alopecia analysis; and comprehensive analyses of body odor components. Statistical analyses will be performed in 2 modes: one to train a joint probability distribution by combining a commercially available health care data set containing large amounts of relatively low-dimensional data with the cross-sectional data set described in this paper and another to individually investigate the relationships among the variables obtained in this study. RESULTS Recruitment for this study started in October 2021 and ended in February 2022, with a total of 997 participants enrolled. The collected data will be used to build a joint probability distribution called a Virtual Human Generative Model. Both the model and the collected data are expected to provide information on the relationships between various health statuses. CONCLUSIONS As different degrees of health status correlations are expected to differentially affect individual health status, this study will contribute to the development of empirically justified interventions based on the population.

Abstract
BACKGROUND Noninvasive detection of early stage cancers with accurate prediction of tumor tissue-of-origin could improve patient prognosis. Because miRNA profiles differ between organs, circulating miRNomics represent a promising method for early detection of cancers, but this has not been shown conclusively. METHODS A serum miRNA profile (miRNomes)-based classifier was evaluated for its ability to discriminate cancer types using advanced machine learning. The training set comprised 7931 serum samples from patients with 13 types of solid cancers and 5013 noncancer samples. The validation set consisted of 1990 cancer and 1256 noncancer samples. The contribution of each miRNA to the cancer-type classification was evaluated, and those with a high contribution were identified. RESULTS Cancer type was predicted with an accuracy of 0.88 (95% confidence interval [CI] = 0.87 to 0.90) in all stages and an accuracy of 0.90 (95% CI = 0.88 to 0.91) in resectable stages (stages 0-II). The F1 score for the discrimination of the 13 cancer types was 0.93. Optimal classification performance was achieved with at least 100 miRNAs that contributed the strongest to accurate prediction of cancer type. Assessment of tissue expression patterns of these miRNAs suggested that miRNAs secreted from the tumor environment could be used to establish cancer type-specific serum miRNomes. CONCLUSIONS This study demonstrates that large-scale serum miRNomics in combination with machine learning could lead to the development of a blood-based cancer classification system. Further investigations of the regulating mechanisms of the miRNAs that contributed strongly to accurate prediction of cancer type could pave the way for the clinical use of circulating miRNA diagnostics.

Abstract
e15120 Background: Many in vivo and in vitro studies have shown that Kampo medicine has various biological and immunological activities, including anti-cancer effect. However, we have little data on efficacy of survival period on MCRC patients (pts) with chemotherapy and Kampo therapy. The aim of this study was to evaluate the survival benefit on MCRC pts treated with Kampo medicine and chemotherapy. Methods: From 2002 to 2007, we treated 66 patients with MCRC. These patients were treated with chemotherapy (CPT-11 + S-1) and/or Kampo medicine (Jyuzen-Taiho-To, TJ-48) on out-patient basis. TJ-48 was given orally at a dose of 7.5g, three times daily. We randomly divided the MCRC pts following two treatment groups; chemotherapy plus Kampo medicine (Group A, n=33) and chemotherapy only (Group B, n=33). Results: Pts and tumor characteristics were much the same between the two groups at baseline. Pts treated with Kampo medicine in combination with chemotherapy (Group A) had a median survival of 20.5 months compared with 15 months for Group B (p=0.12). One and 2 years survival rates were 72% and 13%. No toxic death was reported. The overall 1, 2 and 3 years survival rate were 69, 24 and 12% respectively in Group A, 57, 0 and 0% in Group B. Adverse events did not increase in Group A. TJ-48 is low cost medicine ($1.8 / day). All patients were treated on an out-patient clinic. Conclusions: These results confirmed that the Kampo medicine is helpful and capable of prolonging the survival periods in pts with MCRC. No significant financial relationships to disclose.

Abstract
Disrupted-In-Schizophrenia 1 (DISC1) was identified as a novel gene disrupted by a (1;11)(q42.1;q14.3) translocation that segregated with schizophrenia in a Scottish family. Predicted DISC1 product has no significant homology to other known proteins. Here, we demonstrated the existence of DISC1 protein and identified fasciculation and elongation protein zeta-1 (FEZ1) as an interacting partner of DISC1 by a yeast two-hybrid study. FEZ1 and its nematode homolog are reported to represent a new protein family involved in axonal outgrowth and fasciculation. In cultured hippocampal neurons, DISC1 and FEZ1 colocalized in growth cones. Interactions of these proteins were associated with F-actin. In the course of neuronal differentiation of PC12 cells, upregulation of DISC1/FEZ1 interaction was observed as along with enhanced extension of neurites by overexpression of DISC1. The present study shows that DISC1 participates in neurite outgrowth through its interaction with FEZ1. Recent studies have provided reliable evidence that schizophrenia is a neurodevelopmental disorder. As there is a high level of DISC1 expression in developing rat brain, dysfunction of DISC1 may confer susceptibility to psychiatric illnesses through abnormal development of the nervous system.

Abstract
Bcl10 was identified as a candidate gene responsible for low grade B cell lymphomas of mucosa-associated lymphoid tissue. Overexpression of Bcl10 in cultured cells was reported to promote apoptosis, however, the mechanism of regulation of apoptosis mediated by Bcl10 has not been demonstrated. In the present study, we analysed the apoptosis signaling pathway mediated by Bcl10, focusing on phosphorylation of Bcl10 and the dynamic interaction with its binding partners during apoptosis. Previously, we have demonstrated that Bcl10 potentially interacts with the other apoptosis regulator, TNF receptor associated factor-2 (TRAF2) and inhibitor of apoptosis proteins (cIAPs). The present results showed that the complex formation of these molecules was regulated by phosphorylation of Bcl10, that is, phosphorylation of Bcl10 resulted in binding of Bcl10 to cIAPs and the dissociation of it from TRAF2. Moreover, hyperphosphorylation of Bcl10 enhanced apoptosis, suggesting that changes in the binding partners of Bcl10 were correlated to the promotion of apoptosis as mediated by Bcl10. Indeed, the mutant which was deleted from the binding site of Bcl10 for cIAPs, could not induce apoptosis. These findings indicate that Bcl10 is a mediator of apoptosis signaling, by switching over binding to cIAPs from TRAF2 through the events of Bcl10 phosphorylation.

Abstract
When accumulation of a malfolded protein in the endoplastic reticulum (ER) is induced by various adverse conditions, such as hypoxia, glucose starvation, and perturbation of calcium homeostasis, cells respond to the stress by increasing transcription of genes encoding ER molecular chaperones, a process known as unfolded protein response. The signaling is initiated by IRE1s, ER stress sensors. Alternatively, excessive stress to the ER results in apoptosis. Caspase-12 is known to be essential for this ER stress-induced apoptosis. In this study, we analyzed the detailed regulatory mechanisms of IRE1s during ER stress. We identified c-Jun N-terminal inhibitory kinase (JIK) as a binding partner of IRE1alpha, and JIK was seen to modulate IRE1alpha-TRAF2 (tumor necrosis factor receptor-associated factor 2) complex formation and the resultant alteration to c-Jun N-terminal kinase signaling from IRE1s in response to ER stress. We also demonstrated that TRAF2 interacts with procaspase-12 and promotes the clustering of procaspase-12 and its activation by cleavage in response to ER stress. These results indicate that TRAF2 plays crucial roles not only in the signaling of the c-Jun N-terminal kinase pathway but also in activation of caspase-12 to transduce signals from IRE1s. Thus, we provide a missing link in the ER stress-induced apoptosis-signaling pathway, one which connects the stress sensor molecule IRE1 and the activation of caspase-12.

We have determined the nucleotide sequences around the junction points of oligomeric-deleted ptDNAs possessing a head-to-head or tail-to-tail configuration from long-term cultured cell lines and albino plants. It was shown that DNA rearrangement occurred by direct fusion of deleted ptDNAs in an inverted orientation, which was linked by an asymmetrical sequence of 254-698 bp derived from either of the ptDNAs joined. It is notable that inverted repeats of 7-14 bp flank the asymmetrical sequences at each of the junction points. These features of the DNA sequence around the junction points are commonly observed in oligomeric ptDNA with a large-scale deletion regardless of the cell lines employed. It is suggested that the short inverted repeats are involved in the intermolecular recombination of ptDNA.

Abstract
To investigate the rearrangement of the plastid genome during tissue culture, DNA from rice callus lines, which had been derived individually from single protoplasts isolated from seed or pollen callus (protoclones), was analyzed by Southern hybridization with rice chloroplast DNA (ctDNA) clones as probes. Among 44 long-term cultured protoclones, maintained for 4, 8 or 11 years, 28 contained plastid DNA (ptDNA) from which portions had been deleted. The ptDNA of all protoclones that had been maintained for 11 years had a deletion that covered a large region of the plastid genome. The deletions could be classified into 15 types from their respective sizes and positions. By contrast, no deletions were found in the ptDNA of 38 protoclones that had been maintained for only 1 month. These results indicate that long-term culture causes deletions in the plastid genome. Detailed hybridization experiments revealed that plastid genomes with deletions in several protoclones were organized as head-to-head or tail-to-tail structures. Furthermore, ptDNAs retained during long-term culture all had a common terminus at one end, where extensive rearrangement is known to have occurred during the speciation of rice and tobacco. Morphological analysis revealed the accumulation of starch granules in plastids and amyloplasts in protoclones in which the plastid genome had undergone deletion. Our observations indicated that novel structural changes in the plastid genome and morphological changes in the plastid had occurred in rice cells during long-term tissue culture. Moreover, the morphological changes in plastids were associated with deletions in the plastid genome.

Abstract
To our knowledge, this is the first report of high-frequency thermocoagulation applied to the spinal root. We treated 34 patients suffering from cancer pain with this technique. Among these patients, cancer pain occurred due to intrapelvic metastasis in 11 patients, and 13 complained of chest pain due to cancer. Every patient was considered to have good or excellent response when his or her pain score was reduced to 6 points or less from the score before thermocoagulation; 10 points. Based on this criterion, 54.5% and 30.8% of the above-mentioned patients showed good and excellent responses respectively one month after treatment. This technique, therefore, was considered to be effective with less side effects compared with other nerve blocking techniques.

Abstract
Rice (Oryza sativa L. var. Nipponbare) suspension callus was exposed to gravity stress at 450,000 g for 2 hours, after which poly(A)+RNA was isolated and a cDNA library was constructed. Three different gravity specific cDNAs, namely, GSC 128, GSC 233 and GSC 381 of 0.67, 0.60 and 0.68 kilobase pairs and transcripts of 1.9, 1.6 and 2.0 kb, respectively, were isolated by differential screening and Northern hybridization. The maximum level of transcript was achieved after 4 hours of exposure to gravity at 450,000 g for GSC 128, 2 hours for GSC 233 and 8 hours for GSC 381 followed by a gradual decrease to undetectable levels with the extension of gravitation time. Callus (GSC 128), shoot and callus (GSC 381) and root and callus (GSC 233) specific expression of transcripts was identified. Although the protection of callus by treatment with ABA, kinetin and sucrose extended the period of expression of mRNA in suspension callus after gravity exposure, the expression of gravity-inducible mRNA was exclusively regulated by the degree of callus viability or survival after the stress. In addition, we demonstrated that the level of GSC 381 transcript was markedly increased by exposing the cell to periodical gravity stress, suggesting that this mRNA is expressed and translated into special proteins which are closely related to the survival of the cell against gravity stress. The sequence of GSC 233 and GSC 381, consisting of 417 and 531 base pairs of the longest open reading frames, encode polypeptides with calculated molecular weights of 15.29 and 19.47 kDa, respectively. A sequence homology search against a data bank revealed that GSC 233 and GSC 381 differed from other stress inducible genes in terms of the coding sequence and expression characteristics.

Abstract
Polyadenylated RNA was isolated and a cDNA library constructed from seedlings of a chilling-tolerant rice cultivar (Oryza sativa L. subsp. Japonica cv Nipponbare). Four clones were isolated by differential screening. Northern blot hybridization using RNAs from chilling-tolerant (Nipponbare) and -sensitive (IR36) cultivars revealed higher steady-state levels of transcripts for the four genes in Nipponbare than in IR36 maintained at the same low temperatures. The accumulation of transcripts homologous to selected cDNA sequences during chilling were tissue-specific. The nucleotide and deduced amino acid sequences of three clones, pBC121, pBC442, and pBC591, were determined, and no homology was identified by comparison with the latest version of EMBL and LASL gene data bases. The deduced protein sequences from the longest open reading frame of the clones pBC121 and pBC442 are rich in leucine and serine, whereas that of the clone pBC591 contains arginine-rich basic domains.

Abstract
A 47-year-old woman who was diagnosed as progressive systemic sclerosis (PSS) had acute and severe interstitial pneumonia. Based on the results of her chest roentgenogram, computed tomography, transbronchial lung biopsy (TBLB) and bronchoalveolar lavage (BAL), her interstitial pneumonia was considered to be atypical of PSS. Although she was treated with corticosteroid, methylprednisolone pulse therapy and immunosuppressive drug, the effect of these drugs was insufficient as treatment for the interstitial pneumonia. Therefore, plasma exchange was attempted. After plasma exchange was carried out for three days, her symptoms improved as well as the laboratory data and chest roentgenogram without any severe side effects. We recommend plasma exchange for interstitial pneumonia of PSS as an effective treatment.

Abstract
Three members have been isolated of an additional glutelin gene subfamily, named subfamily B, consisting of about five members per haploid rice genome. Restriction fragment length polymorphism analysis showed major differences between Japonica and Indica lines, indicating the divergence of the subfamily since the split between the two varieties. While corresponding exons of the subfamily B showed 80 to 88% nucleotide sequence homology, those exons were only 60-65% homologous to those of the glutelin A subfamily, distinguishing them from the subfamily A. Intron position and derived polypeptide structure, in addition to the nucleotide sequence, confirm the subfamily B members as glutelins. Analysis of RNA from seeds of different stages of development showed that the subfamily B members were expressed at the same time as those of subfamily A, demonstrating coordinated regulation of the two subfamilies.

Abstract
Shifts in mobility caused by binding of Ca2+ to calmodulin and parvalbumin were studied using high-performance capillary electrophoresis in a Tris-glycine buffer, rather than conventional polyacrylamide gel electrophoresis which requires larger amounts of sample and longer assay time. A Zn(2+)-binding protein, carbonic anhydrase, also showed a partial shift in mobility following Zn(2+)-binding.

Abstract
A new cDNA and two genomic genes encoding the rice storage protein glutelin were isolated and sequenced. The nucleotide sequence of one gene (GluA-3) was completely identical with that of the new cDNA identified here, and the other (GluA-4) was a pseudogene. These glutelin genes were closely related to each other, and belonged to the subfamily A containing the type I (GluA-1) and II (GluA-2) glutelin genes. The Northern blot analysis, using synthetic oligonucleotide specific to the GluA-3 gene as a probe, showed that this gene was expressed earlier than other glutelin genes during seed maturation.

Abstract
The 5' upstream region of the rice storage protein type II glutelin gene was examined for its regulatory function in transgenic tobacco. Chimeric genes containing 5' flanking regions of the glutelin gene transcriptionally fused to the beta-glucuronidase (GUS) reporter gene were introduced into the tobacco genome by Agrobacterium tumefaciens-mediated gene transfer. The chimeric genes were expressed specifically in developing seeds, as opposed to leaves and stems, of the transgenic tobacco. Histochemical analysis revealed that the GUS activity was restricted to the endosperm tissue. A deletion series of the 5' flanking region was created from position -1329 to -74 relative to the transcriptional initiation site and similarly examined in transgenic tobacco. Measurement of GUS activity of the seeds from the transgenic plants bearing the chimeric genes indicated that the region between positions -441 and -237 was required for the temporal and endosperm-specific expression of the GUS activity in tobacco. RNA analysis by northern blotting confirmed the importance of the -441 to -237 region. Addition of up to 888 bp to the -441 deletion resulted in little increase in GUS activity, although all constructs expressing the GUS gene showed a similar tissue and temporal regulation pattern.

Abstract
The 5' flanking region of a glutelin gene was analyzed for interactions with nuclear proteins from immature rice seed. The specific region between positions -272 and -99 was shown to interact with nuclear proteins from immature seeds, but not with those of leaves and roots. Methylation interference experiments revealed that one factor interacted with a specific sequence element between positions -130 and -120 relative to the transcriptional start site. The sequence specificity of this DNA-protein interaction was confirmed by competition experiments using synthetic oligonucleotides. By using a synthetic oligonucleotide as a probe it was also shown that the binding activity was closely correlated with the mRNA levels of this gene during seed maturation.

Abstract
The stress distributions in the laminate veneers under the two kinds of loadings are analyzed numerically by use of FEM in order to make clear the defects of various enamel preparations and Young's modulus of laminate shell materials in restored teeth. The analytical results are summarized as follows, 1) In both cases of two loading conditions under in this study, the stress distribution in restored teeth varied much with Young's modulus of laminate shell materials. 2) Especially in the case of thin enamel preparation in marginal light-chamber configuration, the higher tensile stress is obtained under the higher Young's modulus in the resin cement layer near the labio-gingival margin. 3) When the high load is applied normal to the incisal edge, considering each material strength, however what kind of laminate shell materials are used, the restored teeth is quite within the bounds of possibility for exploration in facio-gingival region or fracture in vicinity of loading points.

Abstract
We studied the formation of pulmonary edema on 9 patients with paraquat poisoning using thermal-sodium double indicator dilution method for the measurement of lung water. In survivors group (n = 4) extravascular thermal volume (EVTV) was not almost changes. In non-survivors group (n = 5) EVTV increased about three times as much as that in survivors group on 32 hours after admission. EVTV was correlated with PCP-PCOP in both survivors group and non-survivors group (n = 64, r = 0.665, p less than 0.01). But EVTV in non-survivors group was higher than that in survivors group within same PCP-PCOP. In non-survivors group delta EVTV/delta (PCP-PCOP) in 24 hours after admission was correlated with initial PCP-PCOP (r = 0.984, p less than 0.01). We propose that the formation of pulmonary edema on paraquat poisoning is mainly due to the increased capillary permeability, influenced by the increased pressure gradient of capillary barrier.

Abstract
We have cloned two types of variable copy number DNA sequences from the rice embryo genome. One of these sequences, which was cloned in pRB301, was amplified about 50-fold during callus formation and diminished in copy number to the embryonic level during regeneration. The other clone, named pRB401, showed the reciprocal pattern. The copy numbers of both sequences were changed even in the early developmental stage and eliminated from nuclear DNA along with growth of the plant. Sequencing analysis of the pRB301 insert revealed some open reading frames and direct repeat structures, but corresponding sequences were not identified in the EMBL and LASL DNA databases. Sequencing of the nuclear genomic fragment cloned in pRB401 revealed the presence of the 3'rps12-rps7 region of rice chloroplast DNA. Our observations suggest that during callus formation (dedifferentiation), regeneration and the growth process the copy numbers of some DNA sequences are variable and that nuclear integrated chloroplast DNA acts as a variable copy number sequence in the rice genome. Based on data showing a common sequence in mitochondria and chloroplast DNA of maize (Stern and Lonsdale 1982) and that the rps12 gene of tobacco chloroplast DNA is a divided gene (Torazawa et al. 1986), it is suggested that the sequence on the inverted repeat structure of chloroplast DNA may have the character of a movable genetic element.

Abstract
The nucleotide sequence of a spacer region between rice 17S and 25S rRNA genes (rDNAs) has been determined. The coding regions for the mature 17S, 5.8S and 25S rRNAs were identified by sequencing terminal regions of these rRNAs. The first internal transcribed spacer (ITS1), between 17S and 5.8S rDNAs, is 194-195 bp long. The second internal transcribed spacer (ITS2), between 5.8S and 25S rDNAs, is 233 bp long. Both spacers are very rich in G+C, 72.7% for ITS1 and 77.3% for ITS2. The 5.8S rDNA is 163-164 bp long and similar in primary and secondary structures to other eukaryotic 5.8S rDNAs. The 5.8S rDNA is capable of interacting with the 5' terminal region of 25S rDNA.

The complete nucleotide sequence of a rice nuclear 17S rRNA gene (rDNA) has been determined. The rice rDNA is 1812 bp long and its G + C content is 51.3%. This nucleotide sequence shows 79%, 80% and 80% homology to those of yeast, Xenopus laevis and rat 18S rDNAs, respectively. Divergency of nucleotide sequences is largely attributed to five blocks of highly variable regions, where eukaryotic specific sequences can be observed.
