Abstract
Although many entities have been established within the broad spectrum of Parkinson disease (PD) and atypical parkinsonisms, they are often difficult to differentiate. To clarify the current clinical diagnostic conditions and problems in PD and atypical parkinsonisms, we analyzed volumes of the Annuals of the Pathological Autopsy Cases in Japan. Among 130 105 autopsies conducted from 2007 to 2016 throughout Japan, patients were included in the study if they had been either clinically or pathologically diagnosed with PD, multiple system atrophy (MSA), progressive supranuclear palsy (PSP), or corticobasal degeneration (CBD). Autopsy rates were 6.4% for clinically diagnosed PD, 34.1% for MSA, 16.3% for PSP, and 17.4% for CBD. The specificities and sensitivities of clinical diagnoses were 88.0% and 82.0% for PD, 95.2% and 86.0% for MSA, 82.7% and 73.2% for PSP, and 55.4% and 57.7% for CBD, respectively. Clinical diagnoses had relatively high accuracy, but low autopsy rates are of concern. Many patients with rarer disorders were clinically misdiagnosed with PD, a more common disorder. Autopsy rates, irrespective of specific disorders, should be increased to detect rare diseases. Increasing autopsy rates will increase the available clinical information regarding pathologically confirmed patients and contribute to more accurate clinical diagnoses.

Abstract
OBJECTIVE To investigate the mechanisms underlying the effect of repetitive transcranial magnetic stimulation (rTMS) on post-stroke hemiplegia, we assessed alterations in cerebral glucose metabolism. METHODS Five post-stroke hemiplegic patients (three targeted for upper limb impairment and two targeted for lower limb impairment) aged 62.6 ± 6.1 years (mean ± standard deviation) with a duration since stroke onset of 3.5 ± 3.8 years participated in this preliminary study. Cerebral glucose metabolism was measured twice-before and after rTMS with intensive rehabilitation-using positron emission tomography with [18F]fluorodeoxyglucose. The Asymmetry Index (AI) was calculated to assess laterality of metabolism between the lesional and contralesional motor areas. The alteration rates of AI (%ΔAI) were compared between participants in whom rTMS was effective and ineffective. RESULTS Two of the three upper-limb-targeted patients and one of the two lower-limb-targeted patients showed motor function improvements following rTMS treatment. All three patients who responded to rTMS had improved laterality of cerebral glucose metabolism in motor areas, commonly in the precentral gyrus, with an %ΔAI of approximately 10%. In contrast, the two patients who did not respond to rTMS had no improvements in laterality. CONCLUSIONS These results suggest for the first time that improved glucose metabolism is associated with improved motor function after a combination of rTMS and intensive rehabilitation.

Abstract
BACKGROUND For surveillance projects to be successful, it is important to accurately diagnose all patients, without overlooking any cases. Here, we investigated the present clinical diagnostic accuracy for prion diseases in Japan. METHODS We analyzed volumes of the "Annual of the Pathological Autopsy Cases in Japan", which reported details on 130,105 autopsies conducted from 2007 to 2016 throughout Japan. RESULTS The clinical diagnosis of patients with prion disease had a specificity of 91.3% and a sensitivity of 96.3%. The autopsy rates were estimated as 17.8% for patients with clinically suspected prion disease and as 1.8% for the entire population. CONCLUSIONS Despite the good accuracy of clinical diagnoses of prion diseases, a calculated 78.4 patients with prion disease were expected to have gone undiagnosed during the 10-year study period. However, autopsy is estimated to reveal a maximum of only 13.8 of these clinically undiagnosed patients because of the low autopsy rate. The overall autopsy rate, irrespective of any specific disorder, must increase for effective surveillance projects of disease incidence to be conducted.

Abstract
BACKGROUND Although pure cerebellar ataxia is usually emphasized as the characteristic clinical feature of spinocerebellar ataxia type 6 (SCA6), parkinsonism has been repeatedly described in patients with genetically confirmed SCA6. METHODS We conducted a positron emission tomography study using a combination of [18F]fluoro-L-dopa for dopamine synthesis and [11C]raclopride for dopamine D2 receptor function on six genetically confirmed SCA6 patients, both with and without parkinsonism. To the best of our knowledge, this is the first dopamine receptor imaging study of patients with SCA6. RESULTS Most patients had somewhat decreased dopaminergic function, and this decrease was significant in the caudate nucleus. In addition, one SCA6 patient with parkinsonism had whole striatal dysfunction of both dopamine synthesis and dopamine D2 receptor function. CONCLUSIONS The pathology of SCA6 may not be restricted to the cerebellum, but may also be distributed across various regions, including in both presynaptic and postsynaptic dopaminergic neurons to some degree. Patients with SCA6 may show apparent parkinsonism after the progression of neurodegeneration.

Abstract
Abstract
Introduction/Aim: Retroviral replicating vectors (RRVs) afford a unique strategy for gene therapy targeting cancer cells. By “activating” RRVs with prodrug activator suicide genes, these RRVs become strong gene delivery vehicles that replicate selectively in cancer cells, and stably persist through proviral genomic integration, leading to inducible cell death upon prodrug administration. This strategy has shown highly promising clinical results in early phase trials (published), and is currently being evaluated in an international Phase III clinical trial for patients with recurrent high-grade glioma. Recently, we have also applied RRV-mediated gene therapy to preclinical models of ovarian cancer. The aim of this current study was to evaluate feasibility and efficacy of combination suicide gene therapy using two RRVs encoated (‘pseudotyped') with different envelope proteins and delivering different prodrug activators for the treatment of ovarian cancer.
Methods: Viral spread was monitored in established and primary patient-derived ovarian cancer cell lines (SKOV3, OCI-P5X, OCI-C5X) over the course of ≥27 days using amphotropic murine leukemia virus (AMLV) envelope- and gibbon ape leukemia virus (GALV) envelope-pseudotyped RRVs delivering either fluorescent protein reporter genes (GFP, mStrawberry) or prodrug activator genes (yeast cytosine deaminase, E. coli nitroreductase), either individually or in combination, at various multiplicities of infection (MOI). Flow cytometry for GFP, mStrawberry, and Gag viral protein was used to determine transduction levels and transgene expression levels of RRVs at serial time points. Each therapeutic RRV was tested by MTS assay for its ability to induce cytotoxicity upon exposure to different concentrations prodrug. To determine viral integration and vector stability, PCR of genomic DNA extracted from infected cells was performed using RRV specific primers, and qRT-PCR was performed to determine vector copy number per cell.
Results: All ovarian cancer cell lines tested could be >80% transduced by AMLV- and GALV-pseudotyped RRVs, both individually and in combination, within 6-24 days even after initial inoculation at MOI 0.001, with replication kinetics varying between different cell lines. Both RRVs could stably integrate into the target cell genome without evidence of transgene deletion. MTS assays demonstrated that prodrug activated cytotoxicity led to efficient killing of RRV-transduced ovarian cancer cells in vitro, with synergistic cytotoxicity observed at lower prodrug concentrations after combined treatment.
Conclusion: RRV-mediated prodrug activator gene therapy may be an effective approach for efficiently and selectively inducing cytotoxicity in ovarian cancer cells. These data support further evaluation of this strategy through translational studies in vivo.

Abstract
OBJECTIVE We previously demonstrated that collagenase H (ColH) plays a crucial role in rat islet isolation, whereas collagenase G (ColG) plays only a supporting role. We also showed that collagen III appears to be one of the key targets of ColH based on a mass spectrometry analysis. In the present study, we investigated whether our novel findings in an islet isolation model are universally applicable for other types of cell isolation, such as a hepatocyte isolation, with the use of enzyme blends of recombinant collagenases. METHODS As the first step, the expression of one of the main matrix components, collagen III, on rat pancreatic and hepatic tissues was assessed with the use of immunohistochemical staining. ColG and ColH were expressed in recombinant E. coli carrying expression plasmids for each collagenase. Then the efficiency of the collagenase subtype on rat hepatocyte isolation was evaluated in terms of cell yield with the use of thermolysin combined with either ColG or ColH (n = 3, respectively). RESULTS The expression of collagen III on rat hepatic tissues was dramatically lower than that of rat pancreatic tissues. In the rat hepatocyte isolation, a substantial amount of hepatocytes (0.81 ± 0.11 × 10(6)) were obtained in the ColG group, whereas almost no hepatocytes were retrieved in the ColH group, indicating that the influence of the collagenase subtypes in rat hepatocyte isolation are completely opposite to that observed in rat islet isolation. CONCLUSIONS Considering that the expression of collagen III on hepatic tissues was relatively low and that almost no hepatocytes were retrieved when ColH and thermolysin were used, the present study supports our novel finding that collagen III appears to be one of the key targets of ColH in hepatocyte isolation. Therefore, the semiquantification of collagen III on the target tissues not only may positively contribute to efficient islet isolation, but also may affect other types of cell isolation by optimizing the ColH amount.

Abstract
Onabotulinum toxin type A treatment for post-stroke upper limb spasticity was investigated to contribute to establishing a standard dosage for Japanese patients. A total of 100 patients participated in the study. The outcome one month (33.6±6.5 days) after the treatment was assessed by the Modified Ashworth Scale (MAS) to estimate the mean effect with a 10-unit injection and the standard dosage expected to improve MAS 1 degree. Average improvement of 263 muscles treated with a higher concentration of 10 units diluted in 0.2 ml was 0.207±0.414 degrees, and that of 231 muscles treated with a lower concentration of 10 units in 0.4 ml was 0.149±0.244 degrees without significant difference among diluted concentrations. To improve MAS 1 degree, 64.6±31.1 units were required for the pectoralis major, 51.2±21.3 units for the teres major, 111.7±48.0 units for the biceps brachii, 51.6±26.8 units for the brachioradialis, 54.1±23.2 units for the brachialis, 34.4±10.7 units for the pronator teres, 64.6±27.9 units for the flexor carpi radialis, 62.4±26.8 units for the flexor carpi ulnalis, 58.5±31.1 units for the flexor digitorum profundus, 69.7±35.1 units for the flexor digitorum superficialis, 24.6±13.4 units for the flexor pollicis longus, and 15.6±11.3 units for the adductor pollicis. Although the results shown here had no significant differences among concentrations, increasing the volume would disturb injection into small muscles, so we considered that a lower volume with a higher concentration should assure larger benefits. It is difficult to make effective injections into all spastic muscles within the officially permitted health insurance dosage of 240 units. Hence, it is advisable to increase the applicable upper limit based on safely achieved cumulative experience.

Abstract
OBJECTIVE A common haplotype M2 consisting of minor SNP alleles located in the ANXA5 gene promoter region has been described as a risk factor for various obstetric complications such as recurrent pregnancy loss, pre-eclampsia and pregnancy-related thrombophilic disorder. However, the question of whether it is the maternal or fetal genotype that contributes to the onset of these disorders remains to be resolved. METHODS We analyzed ANXA5 gene variants in the blood and placental tissues from pre-eclampsia patients and normotensive controls. ANXA5 expression was examined by qRT-PCR, Western blotting and immunostaining. Results were compared between M2 and non-M2 carriers. RESULTS The M2 haplotype was found to be significantly frequent in placentas from pre-eclamptic patients relative to the controls (25.5% versus 10%, P = 0.044), In contrast, no significant differences were observed in maternal blood (13.0% versus 11.3%, P = 0.597). The placental expression of ANXA5 mRNA was found to be lower in M2 carriers. When examined by Western blot and immunostaining, the ANXA5 protein levels were found to be affected more by the placental than the maternal genotype. Histological examination of the placentas from the pre-eclamptic patients demonstrated that a placental M2 haplotype correlated more closely than maternal M2 with the severity of perivillous fibrin deposition. CONCLUSIONS Although preliminary, these results suggest that hypomorphic M2 alleles in the in placental ANXA5 promoter, whether transmitted maternally or paternally, might be an essential determinant of an increased risk of pre-eclampsia via local thrombophilia at the feto-maternal interface.

Abstract
High temperature requirement A (HtrA) family proteins are serine proteases that may serve in the quality control of misfolded or mislocalized proteins. Recently, possible involvements of HtrA1 in the normal development of the placenta and in the pathogenesis of pre-eclampsia were reported. In this study, we characterized HtrA4, a previously uncharacterized HtrA protein family member, in pre-eclampsia. Elevated expression levels of placental HtrA4 in pre-eclampsia patients were observed by qRT-PCR. Western blotting also showed an increased production of HtrA4 at the protein level in pre-eclamptic placentas. In normal chorionic villi, HtrA4 protein was more abundant in the cytoplasm of cytotrophoblasts than in syncytiotrophoblasts. In contrast, the amount of HtrA4 protein in syncytiotrophoblasts was dramatically increased in pre-eclamptic placentas. Circulating HtrA4 was detected at higher levels in sera from women with pre-eclampsia than from those with normotensive pregnancies. Serum HtrA4 levels were higher in patients with early onset and inversely correlated with the weights of the newborn and placenta. Furthermore, serum levels correlated with serum PAPP-A and PAPP-A2 levels, indicating a functional role for HtrA4 in the common pathway. These data suggest that increased HtrA4 may be involved in the onset of pre-eclampsia, and elevated levels in sera imply a potential application as a biomarker for this disorder.

Abstract
BACKGROUND Although the ischemic stress of donated organs has been shown to have strong negative effects on islet recovery, the impact on islet quality remains uncertain. In the present study, therefore, we examined the influence of ischemic stress on the expression of inflammatory mediators among isolated islets. MATERIALS AND METHODS Islets were isolated from adult porcine pancreata subjected to 16-hour cold ischemia time (CIT) in addition to 40-minute warm ischemia time (WIT). We evaluated the islet yield, islet loss during the first 24 hours in culture, adenosine diphosphate (ADP)/adenosine triphosphate (ATP) ratio, ATP/DNA ratio, glucose-stimulated respiratory activity, in vivo bioassay, and the expression of inflammatory mediators (tissue factor [TF], [MCP-1], macrophage migration inhibitory factor) on the isolated islets. We also analyzed ATP/DNA ratios of the exocrine tissues during isolation procedures. RESULTS The islet yield, survival rate during culture, and glucose-stimulated respiratory activity were significantly lower in cases of 16-hour CIT plus 40-minute WIT compared with the control group (P < .0001, .0006, and .002, respectively). In contrast, ADP/ATP ratio as well as TF and MCP-1 expressions on the isolated islets were higher among the ischemic group (P = .005, .16, and .005, respectively). During isolation procedures, the ATP/DNA of the exocrine tissues was extremely lower in the ischemic compared to the control group (P < .0001). Notably, however, both ATP/DNA and ADP/ATP ratio of isolated islets were well preserved even in the ischemic group (P = .45 and .40). DISCUSSION These data suggest that ischemic stress during the preservation period negatively affects the energy status of exocrine tissues. Destruction of the exocrine tissues, in combination with warm ischemic stress during the isolation procedures, subsequently decreases isolated islet activity, inducing the expression of inflammatory mediators.

Abstract
Bortezomib is an effective agent for treating multiple myeloma (MM). To investigate the underlying mechanisms associated with acquired resistance to this agent, we established two bortezomib-resistant MM cell lines, KMS-11/BTZ and OPM-2/BTZ, the 50% inhibitory concentration values of which were respectively 24.7- and 16.6-fold higher than their parental cell lines. No activation of caspase and BH3-only proteins such as Noxa was noted in bortezomib-resistant cells after exposure to the drug. The accumulation of polyubiquitinated proteins was reduced in bortezomib-resistant cells compared with the parental cells, associated with avoidance of catastrophic ER stress as assessed by downregulation of CHOP expression. These resistant MM cells have a unique point mutation, G322A, in the gene encoding the proteasome beta5 subunit (PSMB5), likely resulting in conformational changes to the bortezomib-binding pocket of this subunit. KMS-11 parental cells transfected to express mutated PSMB5 also showed reduced bortezomib-induced apoptosis compared with those expressing wild-type PSMB5 or the parental cells. Expression of mutated PSMB5 was associated with the prevention of the accumulation of unfolded proteins. Thus, a fraction of MM cells may acquire bortezomib resistance by suppressing apoptotic signals through the inhibition of unfolded protein accumulation and subsequent excessive ER stress by a mutation of the PSMB5 gene.

Abstract
Here, we report that tumor cells from some patients (23.8%) with Hodgkin lymphoma (HL) are positive for CC chemokine receptor 4 (CCR4). We therefore tested the chimeric anti-CCR4 monoclonal antibody (mAb), KM2760, the Fc region of which is defucosylated to enhance antibody-dependent cellular cytotoxicity (ADCC), as a novel immunotherapy for refractory HL. KM2760 demonstrated a promising antitumor activity in the CCR4-positive HL-bearing mouse model in the therapeutic setting. Although KM2760 did not induce any ADCC mediated by mouse natural killer (NK) cells, it significantly enhanced phagocytosis mediated by mouse monocytes/macrophages against the CCR4-positive HL cell line in vitro. Together with the findings that KM2760 did not exhibit any complement-dependent cytotoxicity or direct antiproliferation activity in vitro, these data indicated that KM2760 exerted its robust in vivo antitumor activity via monocytes/macrophages in mice. In the human system, KM2760 enhanced phagocytic activity mediated by monocytes/macrophages. Furthermore, it induced robust ADCC mediated by NK cells against the CCR4-positive HL cell line in vitro. Thus, it is conceivable that KM2760 would have much more potent antitumor activity in humans than in mice. Collectively, this study strongly indicates that anti-CCR4 mAb could be a novel treatment modality for patients with CCR4-positive HL.

Abstract
Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominant neurodegenerative disorder characterized as an expanded CAG trinucleotide repeats in SCA2 gene resulting in abnormal polyglutamine sequence. We used positron emission tomography (PET) and magnetic resonance imaging (MRI) to clarify metabolic and atrophic changes of the brain in two symptomatic and three asymptomatic individuals who were genetically confirmed for SCA2. PET revealed decreased glucose metabolism in both patients and two of the three asymptomatic carriers in the cerebellum, pons, or both. No PET abnormality was found in the remaining one carrier who had only a very mildly expanded CAG repeat. MRI showed cerebellar and/or pontine atrophic changes in both patients and one of three carriers. The present study suggest that hypometabolism and atrophy of the cerebellum and pons may occur years before the clinical onset of SCA2. PET and MRI may be useful in the early detection of subclinical brain changes associated with SCA2.

Abstract
In clinical medicine, particularly in the newly developing stem cell therapies required to support the practice of regenerative medicine, the measurement of both CD34+ and CD34- hematopoietic stem cells (HSC)/hematopoietic progenitor cells (HPC) is important in obtaining more accurate information about the total HSC/HPC content in various stem/progenitor cell sources. We report the results of an investigation into methods of detecting CD34+ and CD34- HSC/HPC using the immature information (IMI) channel incorporated into the Sysmex XE-2100 and SE-9000 automated hematology analyzers. In this study, CD34+ and CD34- HSC/HPC were separated by immunologic methods and quantified by flow cytometry (FACScan) and IMI channel analysis. In addition, CD34-/CD133+ HSC were prepared by a sequential antibody-based positive selection strategy. These cells appeared in the same area as CD34+ cells in the IMI channel of the automated hematology analyzer. These findings confirmed that an automated hematology analyzer can be used to measure both CD34+ and CD34- HSC. These results may explain the difference in HSC/HPC counts sometimes observed between the automated hematology analyzer and flow cytometric methods for CD34+ measurement. The results of this study demonstrated the potential of automated cell counting methods for measuring HSC content in cellular products for both research and clinical applications.

Abstract
The combination of cytoplasmic male sterility (CMS) in one parent and a restorer gene ( Rf) to restore fertility in another are indispensable for the development of hybrid varieties. We have found a rice Rf-1 gene that restores BT-type CMS by applying a positional cloning strategy. Using linkage analysis in combination with 6,104 BC(1)F(3) progeny derived from a cross between two near-isogenic lines (NILs) differing only at the Rf-1 locus, we delimited the Rf-1 gene to a 22.4-kb region in the rice genome. Duplicate open reading frames ( Rf-1A and Rf-1B) with a pentatricopeptide (PPR) motif were found in this region. Since several insertions and/or deletions were found in the regions corresponding to both the Rf-1A and Rf-1B genes in the maintainer's allele, they may have lost their function. Rf-1A protein had a mitochondria-targeting signal, whereas Rf-1B did not. The Rf-1B gene encoded a shorter polypeptide that was determined by a premature stop codon. Based on the function of the Rf-1 gene, its product is expected to target mitochondria and may process the transcript from an atp6/orf79 region in the mitochondrial genome. Since the Rf-1A gene encodes a 791-amino acid protein with a signal targeting mitochondria and has 16 repeats of the PPR motif, we concluded that Rf-1A is the Rf-1 gene. Nine duplications of Rf-1A homologs were found around the Rf-1 locus in the Nipponbare genome. However, while some of them encoded proteins with the PPR motif, they do not restore BT-type CMS based on the lack of co-segregation with the restoration phenotype. These duplicates may have played diversified roles in RNA processing and/or recombination in mitochondria during the co-evolution of these genes and the mitochondrial genome.

Abstract
Surface cells of the mammalian distal colon are shown to molecularly express the amiloride-sensitive epithelial Na+channel composed of three homologous subunits (α-, β-, and γ-ENaC). However, because basic electrophysiological properties of amiloride-sensitive Na+channels expressed in these cells are largely unknown at the cellular level, functional evidence for the involvement of the subunits in the native channels is incomplete. Using electrophysiological techniques, we have now characterized functional properties of native ENaC in surface cells of rectal colon (RC) of rats fed a normal Na+diet. Ussing chamber experiments showed that apical amiloride inhibited a basal short-circuit current in mucosal preparation of RC with an apparent half-inhibition constant ( Ki) value of 0.20 μM. RT-PCR analysis confirmed the presence of transcripts of α-, β-, and γ-rENaC in rectal mucosa. Whole cell patch-clamp experiments in surface cells of intact crypts acutely isolated from rectal mucosa identified an inward cationic current, which was inhibited by amiloride with a Kivalue of 0.12 μM at a membrane potential of –64 mV, the inhibition being weakly voltage dependent. Conductance ratios of the currents were Li+(1.8) > Na+(1) >> K+(≈0), respectively. Amiloride-sensitive current amplitude was almost the same at 15 or 150 mM extracellular Na+, suggesting a high Na+affinity for current activation. These results are consistent with the hypothesis that a heterooligomer composed of α-, β-, and γ-ENaC may be the molecular basis of the native channels, which are responsible for amiloride-sensitive electrogenic Na+absorption in rat rectal colon.

Abstract
We describe two male siblings with diabetes mellitus caused by mitochondrial 3243 mutation. The level of heteroplasmy in peripheral blood leucocytes was determined by a last-cycle hot PCR method. The younger brother, who had 39% heteroplasmy, developed diabetes at age of 25, and demonstrated a lean body habitus and blunted insulin secretion. The elder brother, who had 22% heteroplasmy, was diagnosed at the age of 42. The younger brother showed a higher increment of serum lactate after exercise. In these siblings the level of heteroplasmy in their peripheral blood leucocytes appeared to be associated with age of onset of diabetes.

Abstract
In clonality assays using X chromosome inactivation patterns (XCIPs), several factors such as constitutive and acquired XCIP skewing, lack of appropriate controls for hematopoietic diseases including multilineage disorders, and ambiguous criteria for monoclonality, have complicated determination of clonality. To address these issues, we studied the significance of the buccal epithelium as a non-hematopoietic control and the usefulness of the 95% rejection limit as a criterion for monoclonality. Sixty-nine females informative for human androgen receptor gene (HUMARA) were divided into "young," "middle-aged" and "elderly" groups. When XCIP correlation between the buccal epithelium, peripheral granulocytes, and peripheral lymphocytes was analyzed, the buccal epithelium showed a good correlation with granulocytes and lymphocytes in "young" and "middle-aged" groups, whereas the correlation was poor for the "elderly" group. For all age groups, there was an excellent correlation between granulocytes and lymphocytes. When we performed clonality assay for seven "young" and "middle-aged" patients with various leukemic phases using buccal epithelium as a non-hematopoietic control, all cases were accurately evaluated with the aid of a novel criterion, the 95% rejection limit. Our findings suggest that the buccal epithelium may constitute an effective control, especially when a non-hematopoietic control is required, and that the 95% rejection limit may serve as a statistically-defined criterion for monoclonality.

Abstract
We have isolated a new family of mobile elements, Micron, which occur within microsatellites dispersed throughout the rice (Oryza sativa) genome. The first of these segments, Micron 001, was found in a microsatellite consisting of a (TA)n sequence upstream of the rice phytochrome A (phyA) gene. PCR analysis of related rice species suggests that Micron 001 integrated into this microsatellite locus prior to the divergence of the two wild species O. rufipogon and O. barthii from a common ancestor. Micron elements are short (393-bp), possess subterminal inverted repeats and the single strands have the potential to form stable secondary structures via several internal repeats. Aside from the absence of terminal inverted repeats, these characteristics resemble those of MITEs (Miniature Inverted-Repeat Transposable Elements). We estimate that 100-200 copies of Micron-related sequences are present in the rice nuclear genome, while the chloroplast and mitochondrial genomes lack this sequence. Nineteen homologs of Micron 001 exhibited extremely high nucleotide sequence conservation (greater than 90%), suggesting a recent spread of Micron elements within the genus Oryza. Surprisingly, nucleotide sequence alignments showed that all of the Micron elements are flanked on both sides by microsatellite sequence consisting mainly of (TA)n. Twenty-three elements were mapped to seven separate chromosomes. Therefore Micron elements form a family of dispersed, highly conserved repeats. This is the first report of a transposable element that targets microsatellite loci.

Abstract
T4-binding globulin (TBG) is the major thyroid hormone transport protein in human serum. Inherited TBG abnormalities do not usually alter the metabolic status and are transmitted in X-linked inheritance. A high prevalence of complete TBG deficiency (TBG-CD) has been reported among the Bedouin population in the Negev (southern Israel). In this study we report a novel single mutation causing complete TBG deficiency due to a deletion of the last base of codon 38 (exon 1), which led to a frame shift resulting in a premature stop at codon 51 and a presumed truncated peptide of 50 residues. This new variant of TBG (TBG-CD-Negev) was found among all of the patients studied. We conclude that a single mutation may account for TBG deficiency among the Bedouins in the Negev. This report is the first to describe a mutation in a population with an unusually high prevalence of TBG-CD.

Abstract
To establish an efficient screening system for differentially expressed genes of a phytopathogenic fungus Colletotrichum lagenarium, we constructed an equalized (normalized) cDNA library from C. lagenarium and used this library for differential screening. For the isolation of genes involved in infection-related developments of conidia, conidia undergoing appressorium differentiation were selected as the source of materials for construction of the cDNA library. The equalization of cDNA was performed twice using a kinetic method, and the products were cloned into a plasmid vector. Colony hybridization with nine probes of different abundance showed a reduction in abundance variation from at least 276-fold in the original library to 10-fold in the equalized cDNA library, which demonstrated that the cDNA was successfully equalized. By differential hybridization of 1900 cDNA clones in the equalized cDNA library and RNA blot analysis of candidate clones, we identified 11 independent cDNA clones, designated CAD1 through CAD11, that were expressed in appressorium-differentiating conidia, but not in vegetative mycelia. The transcripts of CAD1 and CAD2 hardly accumulated in preincubated conidia, whereas those of CAD3 and CAD4 accumulated highly and slightly, respectively. The amount of the four CAD transcripts increased at the early stage of the appressorium formation process. Sequence analysis of CAD1 revealed that CAD1 would encode for 101 amino acid polypeptides, which showed homology to metallothioneins. Deduced amino acid sequence of CAD2 would encode 278 amino acid polypeptides, and showed high homology to genes in aflatoxin, and sterigmatocystin gene clusters of Aspergillus parasiticus and A. nidulans, respectively.

Abstract
Probiotics are used for various intestinal diseases. However, their effects on gut epithelial cell proliferation have not been investigated. We administered 10(7) colony-forming units of Lactobacillus casei or Clostridium butyricum, or no probiotics (control) by gastric intubation once a day for seven days to rats fed an elemental diet. We estimated the crypt cell production rate of the jejunum, ileum, cecum, and distal colon. We also quantified cecal bacteria. Both probiotics increased the crypt cell production rate of the jejunum and ileum by 25-40%, of the cecum by 70%, and of the distal colon by more than 200% compared with control. Only minor variance in the cecal bacterial composition existed among the three groups. Probiotics enhanced gut epithelial cell proliferation in rats fed an elemental diet.

Abstract
An ancestral sequence of twin microsatellites of rice was found in a wild species. Twin microsatellite loci, RM20A and RM20B, were located on separate regions of chromosomes 11 and 12, which had been duplicated during rice evolution. These twin microsatellites showed different allele diversities in A genome species of the genus Oryza. This difference was caused by repetition of a simple sequence consisting of (TAA)n. Oryza longistaminata contains a short poly(A) sequence in this region instead of the poly(TAA) found in other species. A sequence comparison of RM20-related amplicons suggested that the poly(A)-containing sequence is the ancestral sequence of the RM20A and RM20B microsatellites. A simple base substitution in the poly(A) sequence may have produced the longer microsatellite motif (TAA). This mutation may have occurred on one of the chromosomes of a hypothetical ancestor of the A genome species before duplication of the chromosome segments.

Abstract
It is well known that urine-concentrating ability decreases with aging and that this decreasing ability results from a reduced sensitivity of the renal collecting duct to arginine vasopressin (AVP). AVP regulates the water channel (aquaporin-2:AQP2) through V2 receptors and increases the water permeability of the collecting duct. To elucidate the mechanism of change with aging in urine-concentrating ability, we investigated the change of V2 receptor and AQP2 mRNA expression in young (8-week-old) and older (7-month-old) rats after dehydration for 2 days. After dehydration, plasma AVP levels in older rats were higher than young rats, and urinary osmolality in older rats was lower than young rats. By Northern blot analysis, there was no significant difference between young and older rats in both V2 receptor and AQP2 mRNA expression before dehydration. After dehydration, V2 receptor mRNA expression in young and older rats decreased in the same degree, suggesting the downregulation of V2 receptors may occur in the mRNA level. Northern blot analysis and in situ hybridization histochemistry showed that AQP2 mRNA expression increased and the increased expression in older rats was less than in young rats. The present study suggests the reduced response of AQP2 mRNA expression to dehydration, observed in 7-month-old rats, might be partially responsible for the decreasing urine-concentrating ability with aging.

Abstract
The localization of Cu/Zn- and Mn-superoxide dismutase (SOD) in breast cancer tissue (12 papillotubular carcinomas, 21 solid-tubular carcinomas, 16 scirrhous carcinomas, 1 medullary carcinoma, 1 secreting carcinoma, 1 lobular carcinoma, 1 Paget's disease) was investigated via an immunohistochemical technique using antihuman Cu/Zn- and Mn-SOD antibodies in 10%formalin fixed-paraffin embedded thin sections. Both SODs stained strongly in the normal breast gland, but not clearly in many cancer tissues. Furthermore, Cu/Zn-SOD stained more strongly in well differentiated tubular carcinomas than in poorly differentiated tubular carcinomas. It tended to stain less in tumors which recurred or had a poor outcome, and in tumors with a diploid pattern on DNA flow cytometry. Mn-SOD staining was similar to that of Cu/Zn-SOD, but no significant differences among subgroups was found, since the incidence of positively staining tumors was too small in all groups. The intensity of SOD staining seems to change in relation to cell proliferation and differentiation in breast carcinoma, and may be a prognostic indicator, since SOD decreased in poorly differentiated carcinoma and in tumors which developed distant metastasis. Thus, the localization of SOD in breast cancer tissue can provide useful information for cancer treatment.

Abstract
The characteristics of body type, serum lipids and blood pressure in male blue workers were evaluated. The subjects were 1,705 healthy men aged 40.3 +/- 4.33 years, and were classified into 4 groups according to body mass index: BMI; lean (group L: BMI < 20), normal (group N: 20 < or = BMI < 24), mildly obese (group MO: BMI 24 to 26.5) and obese group (group O: BMI > 26.5). The physical characteristics, blood pressure and 14 blood constituent items were measured. Groups L, N, MO and O accounted for 8.5, 53.4, 28.6, and 9.4% of all subjects, that is the obese body type (MO and O groups) occupied 38%. Rest systolic and diastolic blood pressure were positively related to BMI. Most blood constituent items biochemically analyzed increased in proportion to BMI values. The Trigriceride level was 88.5, 112.2, 152.8 and 171.9 mg/dl in groups L, N, MO and O, respectively. The Trigriceride level in groups MO and O were about the upper limit of the normal range. The total cholesterol level was in the normal range in 4 groups, but was higher in the MO and O groups than in groups L and N. The HDL-cholesterol level was low in inverse proportion to BMI, that is 58.2, 51.3, 47.6, and 42.6 mg/dl in groups L, N, MO, and O, respectively. Especially the values in group O were similar to the values in the aged and adult disease patients. A greater percentage of Japanese male workers were obese men and they risked developing atherosclerosis and adult diseases. the present study suggests that health education regarding exercise prescription and nutrition intake in daily life should be provided.

Abstract
Microsatellites consisting of AT repeats are highly polymorphic in rice genomes and can be used to distinguish between even closely related japonica cultivars in Japan. Polymorphisms of 20 microsatellite loci were determined using 59 japonica cultivars, including both domestic and modern Japanese cultivars. Although the polymorphisms of these 20 microsatellite loci indicated that the Japanese cultivars were genetically quite similar, microsatellites consisting of AT repeats showed high gene diversity even among such closely related cultivars. Combinations of these hypervariable microsatellites can be employed to classify individual cultivars, since the microsatellites were stable within each cultivar. An identification system based on these highly polymorphic microsatellites could be used to maintain the purity of rice seeds by eliminating contamination. A parentage diagnosis using 17 polymorphic microsatellite loci clearly demonstrated that plants which carried desired chromosome regions had been selected in breeding programs. Thus, these hypervariable microsatellites consisting of AT repeats should promote the selection of plants which carry desired chromosomes from genetically similar parents. Backcrossing could also help to eliminate unnecessary chromosome regions with microsatellite polymorphisms at an early stage in breeding programs.
