Abstract
High precision measurements of the ground state hyperfine structure (HFS) of muonium is a stringent tool for testing bound-state quantum electrodynamics (QED) theory, determining fundamental constants of the muon magnetic moment and mass, and searches for new physics. Muonium is the most suitable system to test QED because both theoretical and experimental values can be precisely determined. Previous measurements were performed decades ago at LAMPF with uncertainties mostly dominated by statistical errors. At the J-PARC Muon Science Facility (MUSE), the MuSEUM collaboration is planning complementary measurements of muonium HFS both at zero and high magnetic field. The new high-intensity muon beam that will soon be available at H-Line will provide an opportunity to improve the precision of these measurements by one order of magnitude. An overview of the different aspects of these new muonium HFS measurements, the current status of the preparation for high-field measurements, and the latest results at zero field are presented.

Abstract
For a sagittal split ramus osteotomy to be secure, the relation between the outer and inner contours of the cortex at the inferior border of the mandible is critical. The lowest point of the outer contour is not always immediately below that of the inner contour, and the former is placed more lingually than the latter in about a third of all cases. This tendency is much more noticeable in skeletal class I and II malocclusions than class III. It is therefore important to examine the lowest point of the inferior border in every case, and to carry the inferior part of the buccal cut on to the lingual side if necessary.

Abstract
Culture-based identification methods have been the gold standard for the diagnosis of fungal infection. Currently, molecular technologies such as real-time PCR assays with short turnaround time can provide desirable alternatives for the rapid detection of Candida microbes. However, most of the published PCR primer sets are not Candida specific and likely to amplify DNA from common environmental contaminants, such as Aspergillus microbes. In this study, we designed pan-Candida primer sets based on the ribosomal DNA-coding regions conserved within Candida but distinct from those of Aspergillus and Penicillium. We demonstrate that the final two selected pan-Candida primer sets would not amplify Aspergillus DNA and could be used to differentiate eight medically important Candida pathogens in real-time PCR assays based on their melting profiles, with a sensitivity of detection as low as 10 fg of Candida genomic DNA. Moreover, we further evaluated and selected species-specific primer sets covering Candida albicans, Candida glabrata, Candida tropicalis, and Candida dubliniensis and show that they had high sensitivity and specificity. These real-time PCR primer sets could potentially be assembled into a single PCR array for the rapid detection of Candida species in various clinical settings, such as corneal transplantation.

Abstract
We examined the microbial composition in the diseased lung and early-phase microbial cultures from the blood of a patient with a rapidly progressing fatal pulmonary illness. Although no microbes could be isolated from such cultures during the initial study, the HTS-microbiome study revealed the presence of a unique mixture of alphaproteobacteria, composed mainly of different families of Rhizobiales microbes. Microbial 16S rDNA sequences matching closely to Afipia cberi were identified mainly in the patient's diseased lung tissue, but only rarely in the early-phase blood cultures. Conversely, the high abundance of sequences found in early-phase blood cultures of different broth media matched closely with those of the families Methylobacteriaceae, Phyllobacteriaceae and Sphingomonadaceae. The two species that successfully adapted to grow in a laboratory culture system were A. cberi and Mesorhizobium hominis, which eventually were isolated from a previously cryopreserved blood culture of SP4 broth. Many other species, including members of the Bradyrhizobiaceae and Phyllobacteriaceae families, and all members of the Methylobacteriaceae and Sphingomonadaceae families identified by HTS remained non-cultivated. We developed specific PCR primers and FISH probes, which detected the target Rhizobiales microbes in former blood cultures and autopsy lung tissues. It is unclear what role these Rhizobiales microbes might have played in the patient's complex disease process. However, the above mentioned assays should help in rapidly detecting and identifying these previously unrecognized Rhizobiales microbes in patients.

Abstract
Using Streptococcus pyogenes as a model, we previously established a stepwise computational workflow to effectively identify species-specific DNA signatures that could be used as PCR primer sets to detect target bacteria with high specificity and sensitivity. In this study, we extended the workflow for the rapid development of PCR assays targeting Enterococcus faecalis, Enterococcus faecium, Clostridium perfringens, Clostridium difficile, Clostridium tetani, and Staphylococcus aureus, which are of safety concern for human tissue intended for transplantation. Twenty-one primer sets that had sensitivity of detecting 5-50 fg DNA from target bacteria with high specificity were selected. These selected primer sets can be used in a PCR array for detecting target bacteria with high sensitivity and specificity. The workflow could be widely applicable for the rapid development of PCR-based assays for a wide range of target bacteria, including those of biothreat agents.

Abstract
We recently isolated and discovered new Bradyrhizobiaceae microbes from the cryopreserved culture broth of blood samples from 3 patients with poorly defined illnesses using modified SP4 media and culture conditions coupled with genomic sequencing. Using a similar protocol, we studied a previously cryopreserved culture broth of blood sample from a patient who had succumbed to an acute onset of fulminant pulmonary illness. We report that two phases of microbial growth were observed in the re-initiated culture. Biochemical and genomic characterization revealed microbes isolated from the first phase of growth were new Afipia species of Bradyrhizobiaceae, tentatively named A. cberi with a ~ 5 MB chromosome that was different from those of all previously known Afipia microbes including the newly discovered A. septicemium. The microbes isolated from the second phase of growth were prominent sugar assimilators, novel Phyllobacteriaceae, phylogenetically most closely related to Mesorhizobium and tentatively named M. hominis with a ~ 5.5 MB chromosome. All A. cberi isolates carry a circular ~ 140 KB plasmid. Some M. hominis isolates possess a circular ~ 412 KB plasmid that can be lost in prolonged culture or passage. No antibiotics resistant genes could be identified in both of the A. cberi and M. hominis plasmids. Antibiotic susceptibility studies using broth culture systems revealed isolates of A. cberi could be sensitive to some antibiotics, but all isolates of M. hominis were resistant to essentially all tested antibiotics. However, the cell-free antibiotics susceptibility test results may not be applicable to clinical treatment against the microbes that are known to be capable of intracellular growth. It remains to be determined if the 2 previously unknown Rhizobiales were indeed pathogenic and played a role in the pulmonary disease process in this patient. Specific probes and methods will be developed to re-examine the diseased lungs from patient's autopsy.

Abstract
To elucidate the mechanism of insulin resistance due to insulin counterregulatory
hormones (ICRHs) and evaluate ICRH secretion kinetics, ICRH concentrations were measured
and correlated with blood glucose levels in 28 type 1 diabetic patients. Blood glucose was
measured before bedtime. Early morning urine samples were collected the next morning
before insulin injection and breakfast. Fasting blood glucose, cortisol, glucagon and
HbA1c levels were measured. Growth hormone (GH), adrenaline, cortisol and C-peptide levels
in morning urine samples were measured; SD scores were calculated for urine GH. The
laboratory values (mean ± SD) were as follows; HbA1c of 8.1% ± 1.4%; pre-bedtime glucose
of 203 ± 105 mg/dl; fasting blood glucose of 145 ± 87 mg/dl; serum cortisol of 21.6 ± 5.5
µg/dl; plasma glucagon of 98 ± 41 pg/ml; urinary GH, 27.2 ± 13.0 ng/gCr; urinary cortisol
of 238 ± 197 ng/gCr; and urinary Adrenaline of 22.9 ± 21.0 ng/gCr. The mean urinary GH SD
score was increased (+1.01 ± 0.70; p=0.000); the mean plasma glucagon lebel (98 ± 41
pg/ml) was not. Fasting blood glucose was positively correlated with plasma glucagon
(R=0.378, p=0.0471) and negatively correlated with urinary cortisol (R=–0.476, p=0.010).
Urinary adrenaline correlated positively with urinary GH (R=0.470, p=0.013) and urinary
cortisol (R=0.522, p=0.004). In type 1 diabetes, GH, glucagon and cortisol hypersecretion
may contribute to insulin resistance, but the mechanism remains unclear.

Abstract
OBJECTIVE Insulin-like growth factor binding protein-1 (IGFBP-1) is known to regulate the bioavailability of insulin-like growth factor (IGF) and the levels of IGFBP-1 are increased in the morning in patients with type 1 diabetes mellitus. We investigated the nocturnal fluctuations of glucose, IGFBP-1, and free IGF-1 levels with three insulin regimens. RESEARCH DESIGN AND METHODS Forty-eight type 1 diabetes patients were divided into three groups according to their basal insulin therapy (continuous subcutaneous insulin infusion [CSII], insulin glargine, NPH insulin). Blood samples were obtained every 2 h between 2 300 h and 0700 h to measure plasma glucose, IGFBP-1 and free IGF-1 levels. RESULTS The dawn phenomenon was more frequent with NPH (62.1%) than with glargine (16.6%, p<0.05) and CSII (14.3%, p<0.05). In the NPH group, the serum IGFBP-1 levels were markedly increased from 21.0+/-3.6 ng/ml at 2 300 h to 200.3+/-21.8 ng/ml at 0700 h and free IGF-1 levels were inversely decreased; these changes were partially suppressed in the CSII and glargine groups. CONCLUSIONS The use of insulin regimens that provide sufficient insulin levels in the early morning can suppress the dawn phenomenon, leading to improved glycemic control. The increase in circulating IGFBP-1 in the morning, as a result of waning of insulin action, lowers free IGF-1 levels and may cause insulin resistance.

Abstract
A negative muon in hydrogen targets, e.g., D2 or D-T mixture, can catalyze nuclear fusions following a series of atomic processes involving muonic hydrogen molecular formation (muon-catalyzed fusion, muCF). The ortho-para state of D2 is a crucial parameter not only for enhancing the fusion rate but also to precisely investigate various muonic atom processes. We have developed a system for controlling and measuring the ortho-para ratio of D2 gas for muCF experiments. We successfully collected para-enriched D2 without using liquid-hydrogen coolant. Ortho-enriched D2 was also obtained by using a catalytic conversion method with a mixture of chromium oxide and alumina. The ortho-para ratio of D2 gas was measured with a compact Raman spectroscopy system. We produced large volume (5-30 l at STP), high-purity (less than ppm high-Z contaminant) D2 targets with a wide range of ortho-para ratios (ortho 20%-99%). By using the ortho-para controlled D2 in muCF experiments, we observed the dependence of muCF phenomena on the ortho-para ratio.

Abstract
UNLABELLED The present study was undertaken to determine the role of P2X3 receptor (P2X3R) on heat hyperalgesia in a newly developed rat model of trigeminal neuropathic pain. The unilateral infraorbital nerve (IoN) was partially ligated by 6-0 silk. To assess heat sensitivity, a vibrissal pad (VP) was placed on a hot plate and the latency until the rats withdrew their head was measured. Mechanical sensitivity of VP was also assessed by the use of von Frey filament. Both heat and mechanical hyperalgesia were observed at the VP ipsilateral to the IoN ligation. The latency to heat stimuli was prolonged after subcutaneous administration of pyridoxal-phosphate-6-azophenyl-2',4'-disulfonic acid (PPADS, P2X1,2,3,5,7,1/5,2/3R antagonist) and 2',3'-O-(2,4,6-trinitrophenyl) adenosine 5'-triphosphate (TNP-ATP, P2X1,3,2/3,1/5R antagonist). The latency was shortened after administration of alpha,beta-methylene ATP (alpha,beta-meATP, P2X1,3,2/3R agonist), although no changes appeared after administration of beta,gamma-methylene-L-ATP (beta,gamma-me-L-ATP, P2X1R agonist). The protein gene product-9.5 and calcitonin gene-related peptide immunoreactive nerve fibers significantly decreased in the VP skin of ipsilateral to the IoN ligation. In the ipsilateral trigeminal ganglion, the number of P2X3-immunoreactive neurons significantly increased in the small cell group. In this study, we developed an experimental model of trigeminal neuropathic pain by partial ligation of IoN, which produced heat and mechanical hyperalgesia in the VP. Pharmacological and immunohistochemical studies revealed that the P2X3R plays an important role in the heat hyperalgesia observed in this model. PERSPECTIVE The study describes the development of a novel model of trigeminal neuropathic pain. Heat hyperalgesia in this model was inhibited by peripheral injection of P2XR antagonists. The results suggest that P2X3R is a potential target for development of a novel therapy for trigeminal neuropathic pain.

Abstract
UNLABELLED We developed a rat model of oral cancer pain by inoculating cancer cells into the lower gingiva. A squamous cell carcinoma (SCC) derived from Fisher rats, SCC-158, was inoculated into the subperiosteal tissue on the lateral side of the lower gingiva in male Fisher rats. Inoculation of cancer cells induced marked mechanical allodynia and thermal hyperalgesia in the ipsilateral maxillary and mandibular nerve area. Infiltration of the tumor cells into the mandible and the completely encompassed inferior alveolar nerve was observed. Calcitonin gene-related peptide (CGRP)-, substance P (SP)-, ATP receptor (P2X(3))-, and capsaicin receptor (TRPV1)-immunoreactive cells strikingly increased in the small-cell group of trigeminal ganglia (TGs) after tumor cell inoculation. The TRPV1-immunoreactive cells also increased in the medium- and large-cell groups. Retrograde tracing combined with immunofluorescence techniques revealed the increased expression of peptides and the receptors in maxillary nerve afferent neurons. These results suggest that inoculation of SCC cells into the lower gingiva produces mechanical allodynia and thermal hyperalgesia, indicating the establishment of a novel rat model of oral cancer pain. Increased expression of CGRP, SP, P2X(3), and TRPV1 in the TG may be involved in the behavioral changes in this model. PERSPECTIVE To clarify the mechanisms of oral cancer pain, we examined the expression of calcitonin gene-related peptide, substance P, ATP receptor P2X(3), and capsaicin receptor TRPV1 in trigeminal ganglia. Characterizations of these molecular systems which mediate pain perception are important to develop novel clinical tools for promoting relief of oral cancer pain.

Abstract
We developed a mouse model of cancer pain to investigate its underlying mechanisms. SCC-7, squamous cell carcinoma (SCC) derived from C3H mice, was inoculated subcutaneously into either the plantar region or thigh in male C3H/Hej mice. Heat and mechanical sensitivity as well as spontaneous behavior were measured at the plantar surface of the ipsilateral hind paw after the inoculation. Inoculated sites were histologically examined, and the expression of capsaicin receptors (TRPV1) was examined in the dorsal root ganglia (DRG) to clarify their potential contribution to pain sensitivity. Inoculation of cancer cells induced marked heat hyperalgesia and mechanical allodynia in the ipsilateral hind paw for two weeks in both plantar- and thigh-inoculation models. Signs of spontaneous pain, such as lifting, licking and flinching of the paw were also observed. However, further growth of the tumor reversed the mechanical allodynia in both plantar- and thigh-inoculation models, and heat hyperalgesia in thigh-inoculation models. Histologically, no infiltration of the tumor cells into the nerve was observed. TRPV1 immunoreactive cells increased in the L5 DRG on day 7, but returned to the control level on day 15 post-inoculation. Intraperitoneal administration of the competitive TRPV1 antagonist capsazepine inhibited hyperalgesia induced by tumor cell-inoculation in either plantar- or thigh-inoculated animals. This study indicated that inoculation of SCC resulted in spontaneous pain, heat hyperalgesia and mechanical allodynia. The altered expression of TRPV1 in the DRG may be involved in behavioral changes in this model.

Abstract
The pathophysiological mechanisms of orofacial deep-tissue pain is still unclear. Previously, P2X receptors (P2XR) in sensory neurons have been shown to play a role in the signal transduction of cutaneous pain. We investigated the functional significance of P2X3R in relation to orofacial deep-tissue pain caused by monoarthritis of the temporomandibular joint (TMJ). Monoarthritis was induced by the injection of complete Freund's adjuvant (CFA) into the unilateral TMJ of the rat. The pain associated with monoarthritis was assessed by the pressure pain threshold (PPT), which was defined as the amount of pressure required to induce vocalization. Fifteen days after CFA-treatment, changes in PPT were examined after injection of P2XR agonists or antagonists into the TMJ. The number of cells expressing P2X3R in trigeminal ganglia (TG) was investigated by immunohistochemistry. Inflamed TMJ showed a continuous decline in PPT during the experimental period (P<0.001). Injection of alpha,beta-meATP, an agonist of P2X1,3,2/3R, dramatically reduced the bilateral PPTs of both inflamed and non-inflamed TMJs (P<0.01) although beta,gamma-me-l-ATP, a selective agonist of P2X1R, did not. The decreased PPTs of inflamed TMJ were reversed either by PPADS, an antagonist of P2X1,2,3,5,1/5,4/5R, or by TNP-ATP, an antagonist of P2X1,3,2/3,1/5R. Immunohistochemically, the number of P2X3R-positive cells increased in the small cell group in TG (P<0.01), whereas there was no change in medium or large cell groups after the CFA-injection. Retrograde tracing confirmed that TMJ neurons in the TG exhibited P2X3R immunoreactivity. Our results suggested that P2X3R plays an important role in orofacial pressure pain caused by monoarthritis of TMJ.

Abstract
BACKGROUND/AIMS Hyperbaric oxygen therapy (HBOT) has been reported to augment oxygen delivery to ischemic tissues and improve the liver dysfunction in clinical cases. HBOT was performed after 90% hepatectomy in rats to determine its effect on the regeneration of remnant liver. METHODS After 90% hepatectomy was performed in 8-week-old male Wistar rats, the animals were subdivided into an HBOT (2 atm abs., 80% O2, 1 h/day, 3 days) group and a non-HBOT group. Members of both groups were sacrificed, usually every 4 h until a maximum of 50 h after hepatectomy, and the liver regeneration rate, the proportion of PCNA-positive cells and the ATP volume in the remnant tissues were examined. RESULTS In the HBOT group, the liver regeneration rate at 36 h and 50 h after operation and the proportion of PCNA positive cells at 8 h was significantly increased compared with the non-HBOT group. The ATP volume in the remnant livers in the HBOT group was also significantly increased at 12 h. CONCLUSION HBOT augmented liver regeneration after hepatectomy by stabilization of energy metabolism induced by oxygen delivery in rats.

Abstract
The authors evaluated the impact of functional posterior rhizotomy (FPR) for children with severely disabled mixed type cerebral palsy (CP). Three quadriplegic children at the age of 3, 4, and 10 years underwent FPR. They were classified as mixed type CP based on the clinical presentation of marked spasticity with dystonic posture. Preoperative Ashworth score of the lower extremity was 3.5, 4.5, 4.8 respectively. Two children showed prominent opisthotonus and all showed severe subluxation of the hip joint. Advanced scoliosis was associated in two children. FPR was performed from L2 to S1 in one child, L2 to S2 in one and L2 to S1/S2 in one based on the result of pudendal mapping. Rootlet cutting rate ranged from 66 to 75%. Postoperatively, Ashworth score dropped to 1.4, 1.2, 1.3, respectively. Functional improvement of the upper extremity and urination were confirmed in two children. Hip subluxation was reduced in one child and remained stable in two. A one-year follow-up review confirmed no relapse of spasticity among them. FPR achieved highly satisfactory surgical effects in children with severe mixed type CP. Although long-term follow-up is mandatory since there was a report of relapsed spasticity after FPR in this particular population of CP, FPR could be a choice of surgery in severely disabled children with mixed type CP.

Abstract
A systematic experimental study on muon-catalyzed fusion was conducted using a series of solid deuterium and tritium mixtures. A variety of conditions were investigated, i.e., tritium concentrations from 20% to 70%, and temperatures from 5 to 16 K. With decreasing temperature, we observed an unexpected decrease in the muon cycling rate (lambda(c)) and an increase in the muon loss probability (W). The origins of these observed changes were interpreted by the temperature-dependence in the dt mu formation process for lambda(c) and that in the muon reactivation process after muon-to-alpha sticking for W.

Abstract
Loop-mediated isothermal amplification (LAMP) is a novel nucleic acid amplification method that amplifies DNA with high specificity, efficiency and rapidity under isothermal conditions using a set of four specially designed primers and a DNA polymerase with strand displacement activity. We have developed a method that accelerates the LAMP reaction by using additional primers, termed loop primers. Loop primers hybridize to the stem-loops, except for the loops that are hybridized by the inner primers, and prime strand displacement DNA synthesis. Although both inner and loop primers react via the loops, they do so by different mechanisms. The LAMP method presented here uses loop primers to achieve reaction times of less than half that of the original LAMP method. Since the total time of analysis including detection is less than 1h, this new method should facilitate genetic analysis, including genetic diagnosis in the clinical laboratory.

Abstract
Muon spin relaxation has been measured in CeCoGe3-xSi(x) at the magnetic/nonmagnetic boundary compositions of x = 1.2 and x = 1.5. Both the alloys are found to exhibit an ordered region and a disordered region. At x = 1.2, short-range magnetic ordering is observed below 0.86 K in the ordered region. The disordered region is paramagnetic and the muon spin-lattice relaxation rate lambda2 in this region displays non-Fermi-liquid (NFL) spin dynamics, i.e., the power law lambda2 proportional to T0.72 which shows the formation of Griffiths phase. lambda2 in the x = 1.5 alloy displays logarithmic (NFL) scaling below 1 K, in agreement with the theory of a T = 0 K magnetic transition.

Abstract
The loop-mediated isothermal amplification (LAMP) is a novel nucleic acid amplification method that uses only one type of enzyme. One of the characteristics of the LAMP method is its ability to synthesize extremely large amount of DNA. Accordingly, a large amount of by-product, pyrophosphate ion, is produced, yielding white precipitate of magnesium pyrophosphate in the reaction mixture. Judging the presence or absence of this white precipitate allows easy distinction of whether nucleic acid was amplified by the LAMP method. Since an increase in the turbidity of the reaction mixture according to the production of precipitate correlates with the amount of DNA synthesized, real-time monitoring of the LAMP reaction was achieved by real-time measurement of turbidity.

Abstract
The mechanisms by which growth factors trigger signal transduction pathways leading to the regulation of c-Fos expression are of great interest. In this study we investigated the effect of hepatocyte growth factor (HGF/SF) and epidermal growth factor (EGF) on the expression of c-fos and its product, c-Fos, in human epithelial cell line MKN74. The expression level of c-Fos protein in HGF/SF-stimulated cells was 5--10-fold higher than that in EGF-stimulated cells, whereas the level of c-fos mRNA induced by HGF/SF was similar to that by EGF. The hyperphosphorylation of eukaryotic initiation factor 4E-binding protein 1 (4E-BP1), indicative of an increased number of translation initiation complexes, was detected only in HGF/SF-induced MKN74 cells. Activation of phosphatidylinositol-3'-OH kinase and FKBP12-rapamycin associated mammalian target of rapamycin (FRAP/mTOR) was observed after the treatment with HGF/SF. Pretreatment with an inhibitor of either one, i.e. LY294002 for phosphatidylinositol-3'-OH kinase or rapamycin for FRAP/mTOR, completely inhibited 4E-BP1 phosphorylation and decreased the c-Fos synthesis induced by HGF/SF down to the level found in EGF-induced cells. These results suggest that the phosphorylation of 4E-BP1 is stimulated by HGF/SF in a manner requiring both phosphatidy-linositol-3'-OH kinase-dependent and FRAP/mTOR-dependent pathways, thereby stimulating c-fos mRNA translation. Regulation of the translation process of c-fos mRNA in addition to the immediate activation of c-fos transcription is necessary for the transient increase in the level of c-Fos protein to stimulate cell proliferation.

Abstract
Papillary carcinoma of the thyroid is a common thyroid malignancy with a relatively good prognosis. However, distant metastases may develop and become threatening, particularly to older patients, in a more aggressive manner. We report herein the clinical, radiological, and pathological findings of a patient with papillary thyroid carcinoma who had a solitary cerebral metastasis. The patient had been suffering from depression and had already undergone a hemithyroidectomy for primary thyroid carcinoma, and was known to have metastatic thyroid carcinoma of the lungs and bone. After the removal of the remnant thyroid gland prior to radioiodine (131I) therapy, he developed additional problems related to depression. Electroencephalography played an important role in identifying suspected brain metastasis and computed tomography demonstrated a space-occupying lesion in the left cerebral hemisphere. Consequently, an early removal of intracranial mass could be performed without any further life-threatening complications. Moreover, after removal of the brain mass the patient's depression improved immediately without the use of any antidepressants. This case report indicates the possibility that a patient's depression might be associated with brain metastasis from papillary thyroid carcinoma, and also suggests that an early diagnosis with the appropriate surgical management of a brain metastasis followed by radioiodine therapy could be valuable for achieving a prolonged disease-free period.

Abstract
Chromosome 21 is the smallest human autosome. An extra copy of chromosome 21 causes Down syndrome, the most frequent genetic cause of significant mental retardation, which affects up to 1 in 700 live births. Several anonymous loci for monogenic disorders and predispositions for common complex disorders have also been mapped to this chromosome, and loss of heterozygosity has been observed in regions associated with solid tumours. Here we report the sequence and gene catalogue of the long arm of chromosome 21. We have sequenced 33,546,361 base pairs (bp) of DNA with very high accuracy, the largest contig being 25,491,867 bp. Only three small clone gaps and seven sequencing gaps remain, comprising about 100 kilobases. Thus, we achieved 99.7% coverage of 21q. We also sequenced 281,116 bp from the short arm. The structural features identified include duplications that are probably involved in chromosomal abnormalities and repeat structures in the telomeric and pericentromeric regions. Analysis of the chromosome revealed 127 known genes, 98 predicted genes and 59 pseudogenes.

Abstract
The AIRE gene (autoimmune regulator), coding for a putative transcriptional regulatory factor, is mutated in autoimmune-polyendocrinopathy-candidiasis ectodermal dystrophy (APECED). We have investigated the expression of the AIRE gene by mRNA in situ hybridization and immunohistochemistry in various human tissues. Here we show that AIRE is expressed in distinct cells in thymus medulla, and also in rare cells in lymph node paracortex and medulla, and in spleen and fetal liver, but not in the target organs of autoimmune destruction. Double immunofluorescence studies revealed that in thymus medulla both epithelial (cytokeratin positive) and non-epithelial cells expressed AIRE. Subcellularly, AIRE was localised in nuclear dots in thymus and lymph node and also in transfected cells. The cellular localisation of AIRE and its nuclear localisation, compatible with its predicted protein domains, suggest that AIRE may regulate the mechanisms involved in the induction and maintenance of immune tolerance.

Abstract
Autoimmune polyendocrinopathy syndrome type 1 (APS-1; MIM# 240300) is a rare autosomal recessively inherited disease characterised by destructive autoimmune diseases of endocrine glands. The gene responsible for APS-1, known as AIRE (for autoimmune regulator), was recently identified and contains motifs suggestive of a transcription regulator. To date, nine APS-1-associated mutations have been identified in the AIRE gene, including two common mutations R257X and 1094-1106del. In addition to these two mutations, we report seven novel mutations in 16 APS-1 patients from North America. We found that 1094-1106del and R257X were the most common mutations in this population of mixed geoethnic origin, accounting for 17/32 and 4/32 alleles, respectively. Haplotype analyses suggest that both are recurrent mutations, occurring on several different haplotypes with closely linked markers. All the novel mutations appear to be rare, occurring in only single APS-1 families. After examining all coding sequences and exon/intron boundaries of the AIRE gene, the other APS-1 allele remained unidentified in three patients. Genotype-phenotype correlations for APS-1 remain difficult, suggesting that other genetic or environmental factors, or both, influence the clinical presentation and disease progression in individual APS-1 patients.

Abstract
We have isolated cDNA clones for a novel human protein, TRPC7 (transient receptor potential-related channels), which consists of 1503 amino acid residues from the fetal brain and caudate nucleus cDNA libraries. Northern blot analysis indicated that the TRPC7 gene is highly expressed as a 6.5-kb transcript in brain. The TRPC7 protein has significant homology with Caenorhabditis elegans hypothetical proteins T01H8.5, C05C12.3, and F54D1.5 and with Drosophila and human transient receptor potential (trp) proteins. The TRPC7 protein has seven putative transmembrane domains that probably constitute a Ca2+ channel as in the above-mentioned proteins. Genomic sequencing revealed that the TRPC7 gene consists of 32 exons spanning approximately 90 kb. The TRPC7 gene was mapped between D21S400 and D21S171 on human chromosome 21q22.3, 14 kb distal to a NotI site in D21S400. This novel TRPC7 gene could be a candidate gene for genetic disorders such as bipolar affective disorder, nonsyndromic hereditary deafness, Knobloch syndrome, and holoprosencephaly, which were mapped to this region.

Abstract
Autoimmune polyendocrinopathy-candidiasisectodermal dystrophy (APECED; also called APS-1,) is a rare autosomal recessive disorder that is more frequent in certain isolated populations. It is characterized by two of the three major clinical symptoms that may be present: Addison's disease, and/or hypoparathyroidism and/or chronic mucocutaneous candidiasis. We have recently identified the gene for APECED, which we termed AIRE (for autoimmune regulator). AIRE is expressed in thymus, lymph nodes and fetal liver, and encodes a protein with two putative zinc fingers and other motifs suggestive of a transcriptional regulator. Seven mutations have been described to date, including R257X, the predominant Finnish and northern Italian APECED allele, which has also been observed in other patients of diverse origin on different haplotypes. A 13-bp deletion (1094-1106del) has also been observed in several patients of different geo-ethnic origin. The other described mutations appear to be rare. We present mutational analyses of the AIRE gene in ten Sardinian APECED families and show that there is a mutation, R139X, associated with one predominant haplotype unique to the Sardinian patients (18/20 independent alleles). The carrier frequency of R139X in Sardinia is 1.7%, giving an estimated population frequency of APECED of 1/14,400. Using linkage disequilibrium data, the estimated age of the R139X mutation is between 20 and 25 generations. A previously described 13-bp deletion was also observed on an allele of one patient. The identification of a single common Sardinian APECED mutation will facilitate its genetic diagnosis. Given the carrier frequency of R139X in the Sardinian population, AIRE may be implicated in the pathogenesis of other autoimmune diseases in the Sardinian population, particularly those affecting the endocrine system.

Abstract
Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED; OMIM *240300, also called APS 1,) is a rare autosomal recessive disorder that is more frequent in certain isolated populations. It is generally characterized by two of the three major clinical symptoms that may be present, Addison's disease and/or hypoparathyroidism and/or chronic mucocutaneous candidiasis. Patients may also have a number of other clinical symptoms including chronic gastritis, gonadal failure, and rarely, autoimmune thyroid disease and insulin-dependent diabetes mellitus. We and others have recently identified the gene for APECED, which we termed AIRE (for autoimmune regulator). AIRE is expressed in thymus, lymph nodes, and fetal liver and encodes a protein containing motifs suggestive of a transcriptional regulator, including two zinc finger motifs (PHD finger), a proline-rich region, and three LXXLL motifs. Six mutations, in cluding R257X, the predominant Finnish APECED allele, have been defined. R257X was also observed in non-Finnish APECED patients occurring on different chromosomal haplotypes suggesting different mutational origins. Here we present mutation analyses in an extended series of patients, mainly of Northern Italian origin. We have detected 12 polymorphisms, including one amino acid substitution, and two additional mutations, R203X and X546C, in addition to the previously described mutations, R257X, 1096-1097insCCTG, and a 13-bp deletion (1094-1106del). R257X was also the common mutation in the Northern Italian patients (10 of 18 alleles), and 1094-1106del accounted for 5 of 18 Northern Italian alleles. Both R257X and 1094-1106del were both observed in patients of four different geo-ethnic origins, and both were associated with multiple different haplotypes using closely flanking polymorphic markers showing likely multiple mutation events (six and four, respectively). The identification of common AIRE mutations in different APECED patient groups will facilitate its genetic diagnosis. In addition, the polymorphisms presented provide the tools for investigation of the involvement of AIRE in other autoimmune diseases, particularly those affecting the endocrine system.

Abstract
Neutropenia is frequently observed in a variety of autoimmune disorders. As the mechanism of neutropenia in these disorders, the destruction of neutrophils by anti-neutrophil autoantibodies has been believed since elevated levels of neutrophil-associated IgG (NAIgG) have been described. However, no data exists to characterize the nature of NAIgG and show NAIgG is an anti-neutrophil autoantibodies. We investigated whether the elevated NAIgG in these patients consists of anti-neutrophil autoantibodies. The NAIgGs of 91 patients with autoimmune disorders including 50 patients with idiopathic thrombocytopenic purpura, 13 patients with systemic lupus erythematosus, 11 patients with Hashimoto's thyroiditis and 10 patients with Graves' disease were analyzed. The level of NAIgG was high in 36 of 91 patients. Elution studies were performed to determine whether NAIgG has a nature of autoantibodies. In model experiments, the ether eluate from neutrophils sensitized with neutrophil-specific alloantibody (anti-NA2) reacted with donor neutrophils, whereas the eluates from those with model immune complexes (ICs) failed. These data indicated that the ether elution technique is useful to determine whether NAIgG consists of anti-neutrophil autoantibodies. The NAIgG on patient's neutrophils was eluted with ether and the reactivity of the eluate with normal neutrophils was investigated. The eluates from 34 of 36 patients with various autoimmune disorders with elevated NAIgG level failed to react with donor neutrophils. These data indicated that the elevated NAIgG in the majority of these patients did not consist of anti-neutrophil autoantibodies, but possibly of ICs.

Abstract
Autoimmune polyglandular syndrome type I (APS 1, also called APECED) is an autosomal-recessive disorder that maps to human chromosome 21q22.3 between markers D21S49 and D21S171 by linkage studies. We have isolated a novel gene from this region, AIRE (autoimmune regulator), which encodes a protein containing motifs suggestive of a transcription factor including two zinc-finger (PHD-finger) motifs, a proline-rich region and three LXXLL motifs. Two mutations, a C-->T substitution that changes the Arg 257 (CGA) to a stop codon (TGA) and an A-->G substitution that changes the Lys 83 (AAG) to a Glu codon (GAG), were found in this novel gene in Swiss and Finnish APECED patients. The Arg257stop (R257X) is the predominant mutation in Finnish APECED patients, accounting for 10/12 alleles studied. These results indicate that this gene is responsible for the pathogenesis of APECED. The identification of the gene defective in APECED should facilitate the genetic diagnosis and potential treatment of the disease and further enhance our general understanding of the mechanisms underlying autoimmune diseases.

Abstract
We isolated cDNAs for a novel protein with a calculated molecular mass of 46 kDa, containing a leucine-rich repeat (LRR) with conserved flanking sequences and a C2-type immunoglobulin (Ig)-like domain. This novel protein was considered to be a new member of the Ig superfamily and was named ISLR (immunoglobulin superfamily containing LRR). These domains are known to be important for protein-protein interaction or cell adhesion, and therefore it is possible that the novel protein ISLR may also interact with other proteins or cells. Northern blot analysis showed the presence of a 2.4-kb transcript in various human tissues including retina, heart, skeletal muscle, prostate, ovary, small intestine, thyroid, adrenal cortex, testis, stomach, and spinal cord as well as fetal lung and fetal kidney. The ISLR gene was mapped on human chromosome 15q23-q24 by fluorescence in situ hybridization.

Abstract
The human PWP2 gene is the human homologue of the yeast periodic tryptophan protein 2 (PWP2) gene and is a member of the gene family that contains tryptophan-aspartate (WD) repeats. Genomic sequencing revealed that the human PWP2 gene consists of 21 exons spanning approximately 24 kb and locates just between the two genes EHOC-1 and KNP-I and distal to a NotI site of LJ104 (D21S1460) on chromosome 21q22.3. Analysis of the 5'-flanking DNA sequence revealed that the upstream region of the PWP2 gene is associated with a CpG island containing the NotI site of LJ104. Since PWP2 is considered to be a candidate for genetic disorders mapped in the 21q22.3 region, the information including nucleotide sequence and genomic organization of the PWP2 gene should be invaluable for the mutation analysis of the corresponding genetic disorders.

Abstract
TMEM1 (EHOC-1) gene encodes a putative transmembrane protein and is located on human chromosome band 21q22.3. Analysis of a 122,638-bp genomic sequence revealed that TMEM1 gene consists of 23 exons spanning approximately 94 kb and is transcribed in the direction of centromere to telomere. The 5' region of the TMEM1 gene was associated with a CpG island and the 3' end of the TMEM1 gene was mapped just proximal to the 5' end of the neighboring gene PWP2. We determined that the TMEM1 gene encodes a protein of 1,259 amino acids, which is 69-amino acids longer than the previously reported sequence. Since TMEM1 gene is considered to be a candidate for genetic disorders mapped in the 21q22.3 region, the information including complete nucleotide sequence and genomic organization of the TMEM1 gene should be invaluable for the mutation analysis of the corresponding genetic disorders.

Abstract
As a step toward identifying the pathogenic genes for autoimmune polyglandular disease type I (APECED) and other disorders mapped to the PFKL locus on chromosome 21q22.3, we have constructed a cosmid/BAC (bacterial artificial chromosome) contig of 450 kb covering markers D21S1460-D21S25-PFKL-D21S154 and performed exon trapping. We isolated 22 distinct exons including 6 exons derived from two known genes (PFKL and EHOC-1). Among 16 novel exons, 2 exons matched with human expressed sequence tags (EST) and 7 exons showed homology at predicted amino acid sequence level with proteins from other species. These 16 exons were mapped back to the cosmid contigs, 12 of which were confirmed for their expression by polymerase chain reaction (PCR) screening of human cDNA libraries of various tissues. These exon sequences and a transcript map will aid for isolation of corresponding genes which will be identified as candidate genes involved in the pathogenesis of disorders mapped to the 21q22.3 region.

Abstract
The authors have developed a solid-phase direct hemadherence assay (SPDHA) to identify red cell-bound antibody without elution. The procedure of SPDHA is as follows: (1) commercially available panel cells were immobilized on the well of microplane; (2) 22% polymerized albumin and 0.3% test red cells were added, and the plate was centrifuged at low speed, and incubated; (3) finally the plate was centrifuged, and the results were read macroscopically. SPDHA could detect antibodies against D, C, c, E, e, Fya, Fyb, K, k, A and B antigens. The sensitivity of SPDHA was high in Rh antibodies as compared with that in the other antibodies. SPDHA failed to detect anti-Jka, -Jkb, -S, -s and -Dia antibodies. In cases of suspected hemolytic disease of newborn, Rh antibodies could be identified using very small volume of red cells. In conclusion, SPDHA is a useful and simple method to identify red cell-bound antibodies, especially when only a small volume of red cell sample is available, such as the sample from fetus or newborn.

Abstract
We have isolated cDNA clones for a novel human protein KNP-I from fetal brain and bone marrow cDNA libraries. Northern blot analysis indicated that the KNP-I gene is ubiquitously expressed in various human tissues. Significant homology of the KNP-I protein with Escherichia coli anti-sigma cross-reacting protein (SCRP-27A) (44% identity) and zebrafish (Brachydanio rerio) esl protein (49% identity) suggested that the KNP-I protein may be involved in a basic cellular function. Genomic sequencing revealed that the KNP-I gene consists of seven exons spanning 12 kb. Exon 5 was involved in alternative splicing. The KNP-I gene was mapped between D21S1460 and D21S25 on human chromosome 21q22.3, 26 kb distal to a Not 1 site of D21S1460. Thus, this novel KNP-I gene could be a candidate gene for autoimmune polyglandular disease type I (APECED) and other disorders mapped to this region.
