Abstract
Chronic granulomatous disease (CGD) is a primary immunodeficiency disease caused by molecular defects in nicotinamide adenine dinucleotide phosphate (NADPH) oxidase. p67phox-CGD is an autosomal recessive CGD, which is caused by a defect in the cytosolic components of NADPH oxidase, p67phox, encoded by NCF2. We previously established a flow cytometric analysis for p67phox expression, which allows accurate assessment of residual protein expression in p67phox-CGD. We evaluated the correlation between oxidase function and p67phox expression, and assessed the relevancy to genotypes and clinical phenotypes in 11 patients with p67phox-CGD. Reactive oxygen species (ROS) production by granulocytes was evaluated using dihydrorhodamine-1,2,3 (DHR) assays. p67phox expression was evaluated in the monocyte population. DHR activity and p67phox expression were significantly correlated (r = 0.718, p < 0.0162). Additionally, DHR activity and p67phox expression were significantly higher in patients carrying one missense variant in combination with one nonsense or frameshift variant in the NCF2 gene than in patients with only null variants. The available clinical parameters of our patients (i.e., age at disease onset, number of infectious episodes, and each infection complication) were not linked with DHR activity or p67phox expression levels. In summary, our flow cytometric analysis revealed a significant correlation between residual ROS production and p67phox expression. More deleterious NCF2 genotypes were associated with lower levels of DHR activity and p67phox expression. DHR assays and protein expression analysis by using flow cytometry may be relevant strategies for predicting the genotypes of p67phox-CGD.

Abstract
An organometallic nickel complex containing thieno[3,2-b]thiophene units was designed and synthesized. Composite films of the resulting nickel complex and polyvinylidene difluoride, which can be fabricated via a simple solution process under atmospheric conditions, exhibit remarkably high n-type conductivity (>200 S cm-1). Moreover, the thermoelectric power factor of the n-type composite film was proven to be air stable. A grazing-incidence wide-angle X-ray diffraction analysis indicated a significant impact of introducing the thieno[3,2-b]thiophene core into the backbone of the nickel complex on the orientation within the composite films.

Abstract
A domino-type multiple C-H functionalization of tetracene with molecular benzene is reported. Under the typical conditions of the Scholl reaction, a domino reaction occurs between tetracene and six molecules of benzene in one pot to furnish an aromatic compound with a curved π-system. This reaction sequence involves oxidative cross-dehydrogenative coupling/annulation and Friedel-Crafts-type reactions. Eight C-C bonds are formed via this intermolecular domino reaction without mediation by a metal or the assistance of a specific substituent.

Abstract
CCAAT/enhancer binding protein epsilon (C/EBPε), a myeloid-specific transcription factor, plays an important role in granulopoiesis. A loss-of-function mutation in this protein can result in an abnormal development of neutrophils and eosinophils, known as neutrophil-specific granule deficiency (SGD). The transcriptional activity of C/EBPε is regulated by interactions with other transcription factors and/or post-translational modification, including acetylation. Previously, we reported a novel SGD patient who had a homozygous mutation for two amino acids, arginine (R247) and serine (S248), which were deleted in the basic leucine zipper domain of C/EBPε (ΔRS) and exhibited loss of transcriptional activity with aberrant protein-protein interactions. In the present study, we found that a single amino acid deletion of either R247 (ΔR) or S248 (ΔS) was sufficient for the loss of C/EBPε transcriptional activity, while an amino acid substitution at S248 to alanine in C/EBPε (SA) had comparable transcriptional activity with the wild-type C/EBPε (WT). Although acetylation at lysine residues (K121 and K198) is indispensable for C/EBPε transcriptional activity, an acetylation mimic form of ΔRS (ΔRS-K121/198Q) did not exhibit the transcriptional activity. Interestingly, we discovered that ΔRS, ΔR, ΔS, and ΔRS-K121/198Q interacted with histone deacetylase 1 (HDAC1), whereas WT and SA did not. Furthermore, the proteoglycan 2/eosinophil major basic protein induction activity of ΔRS, ΔR, and ΔS could be restored by the HDAC inhibitor, trichostatin A (TSA), and protein-protein interactions between ΔRS and Gata1 could also be recovered by TSA treatment. Taken together, our results show that TSA has the potential to restore the transcriptional activity of ΔRS, indicating that the inhibition of HDAC1 could be a molecularly targeted treatment for SGD with ΔRS.

Abstract
Hypersensitivity to mosquito bites (HMB) is a cutaneous disorder belonging to the group of Epstein-Barr virus (EBV)-associated T/natural killer (NK)-cell lymphoproliferative diseases, and is primarily mediated by EBV-infected NK cells. It is characterized by intense local skin reactions accompanied by general symptoms after mosquito bites, and infiltration of EBV-infected NK cells into the bite sites. However, the mechanisms underlying these reactions have not been fully examined. We recently described the activation of circulating basophils by mosquito extracts in vitro in a patient with HMB. To further investigate this finding, we studied four additional patients with HMB. All patients showed typical clinical features of HMB after mosquito bites and they had NK lymphocytosis and high peripheral blood EBV DNA loads. We found evidence of EBV infection in NK cells through in situ hybridization that detected EBV-encoded small RNA-1, and flow cytometry showed HLA-DR expression on almost all NK cells. Basophil activation tests with the extracts of epidemic mosquitoes Culex pipiens pallens and Aedes albopictus showed positive responses to one or both extracts in all samples from patients with HMB, suggesting the presence of mosquito antigen-specific IgE and its binding to basophils. In particular, the extract of Aedes albopictus was able to activate basophils in all available patient samples. These results indicate that basophils and/or mast cells activated by mosquito bites may be involved in initiation and development of severe skin reactions to mosquito bites in HMB.

Abstract
Neutrophil-specific granule deficiency (SGD) is a rare autosomal recessive primary immunodeficiency characterized by neutrophil dysfunction, bilobed neutrophil nuclei and lack of neutrophil-specific granules. Defects in a myeloid-specific transcription factor, CCAAT/enhancer binding protein-ε (C/EBPε), have been identified in two cases in which homozygous frameshift mutations led to loss of the leucine zipper domain. In this study, we report a 55-y-old woman affected with SGD caused by a novel homozygous 2-aa deletion (ΔRS) in the leucine zipper domain of the C/EBPε gene. The patient showed characteristic neutrophil abnormalities and recurrent skin infections; however, there was no history of deep organ infections. Biochemical analysis revealed that, in contrast to the two frameshift mutations, the ΔRS mutant maintained normal cellular localization, DNA-binding activity, and dimerization, and all three mutants exhibited marked reduction in transcriptional activity. The ΔRS mutant was defective in its association with Gata1 and PU.1, as well as aberrant cooperative transcriptional activation of eosinophil major basic protein. Thus, the ΔRS likely impairs protein-protein interaction with other transcription factors, resulting in a loss of transcriptional activation. These results further support the importance of the leucine zipper domain of C/EBPε for its essential function, and indicate that multiple molecular mechanisms lead to SGD.

Abstract
BACKGROUND Nephrotic syndrome (NS) is characterized by water and sodium retention, which leads to edema. The non-osmotic stimulation of arginine vasopressin release from the pituitary gland has been implicated as one of the important factors in abnormal water retention in patients with NS. CASE-DIAGNOSIS/TREATMENT We present the initial description of a patient with massive edema caused by refractory nephrotic syndrome, which was effectively treated with tolvaptan, a selective oral vasopressin V2 receptor antagonist. CONCLUSIONS Tolvaptan is effective for the treatment of massive edema caused by NS. Larger studies are needed in the future to fully assess the value and safety of tolvaptan use for this condition.

Abstract
(Apo)ferritins are cage-shaped proteins which have recently received a great deal of attention because the inner cavity of the protein shell can be used as a size-restricted reaction field for the synthesis of nanomaterials. The biomineralization behavior and inorganic nanoparticle (NP) synthesis mechanism of (apo)ferritin in solution systems have been studied but the mineralization behavior of (apo)ferritin on the substrates has not yet been well studied. Here, we conducted quantitative and kinetic analyses of the mineralization behavior of immobilized (apo)ferritin on a polyelectrolyte multilayer (PEM) using quartz crystal microbalance (QCM), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS) techniques. We demonstrated that the (apo)ferritin immobilized on a substrate synthesizes a ferrihydrite core within the confines of the protein cage; similar to a solution dispersed system. In addition, we applied a ferritin/apoferritin blended monolayer to the study of iron mineralization and revealed that biomineralization in this system is spatially selective. It is important to understand the mineralization mechanisms for the synthesis of other functional NPs as this approach has potential for a broad range of magnetic, catalytic, and biomedical sensing applications.

Abstract
Engaging inhibitory FcγRIIb by Fc region has been recently reported to be an attractive approach for improving the efficacy of antibody therapeutics. However, the previously reported S267E/L328F variant with enhanced binding affinity to FcγRIIb, also enhances binding affinity to FcγRIIa(R131) allotype to a similar degree because FcγRIIb and FcγRIIa(R131) are structurally similar. In this study, we applied comprehensive mutagenesis and structure-guided design based on the crystal structure of the Fc/FcγRIIb complex to identify a novel Fc variant with selectively enhanced FcγRIIb binding over both FcγRIIa(R131) and FcγRIIa(H131). This novel variant has more than 200-fold stronger binding affinity to FcγRIIb than wild-type IgG1, while binding affinity to FcγRIIa(R131) and FcγRIIa(H131) is comparable with or lower than wild-type IgG1. This selectivity was achieved by conformational change of the C(H)2 domain by mutating Pro to Asp at position 238. Fc variant with increased binding to both FcγRIIb and FcγRIIa induced platelet aggregation and activation in an immune complex form in vitro while our novel variant did not. When applied to agonistic anti-CD137 IgG1 antibody, our variant greatly enhanced the agonistic activity. Thus, the selective enhancement of FcγRIIb binding achieved by our Fc variant provides a novel tool for improving the efficacy of antibody therapeutics.

Abstract
Primary Epstein-Barr virus (EBV) infection causes infectious mononucleosis and hemophagocytic lymphohistiocytosis (HLH) in children, where EBV infects B and CD8(+) T cells, respectively. We measured pro-inflammatory and anti-inflammatory cytokines in both diseases. Significantly higher concentrations of various mediators, including interferon-γ, neopterin, interleukin (IL)-6, IL-10, IL-18, and heme oxygenase-1, were observed in EBV-HLH. Because of their similarity to the profile of familial HLH, this profile was likely a consequence of HLH, but not ectopic infection. TNF-α levels were elevated in both diseases. Elevation of those mediators may contribute to the disease pathogenesis of EBV-HLH by activating and inhibiting host immune responses.

Abstract
Chronic granulomatous disease (CGD) is caused by defects of NADPH oxidase. The diagnosis of CGD can be made by analysis of NADPH oxidase activity, however, identification of the CGD subgroups is required before performing mutation analysis. The membrane-bound subunits, gp91phox and p22phox, can be quickly analyzed by flow cytometry, unlike the cytosolic components, p47phox and p67phox. We evaluated the feasibility of flow cytometric detection of p47phox and p67phox with specific monoclonal antibodies in two patients with p47phox deficiency and 7 patients with p67phox deficiency. Consistent with previous observations, p47phox and p67phox were expressed in phagocytes and B cells, but not in T or natural killer cells, from normal controls. In contrast, patients with p47phox and p67phox deficiency showed markedly reduced levels of p47phox and p67phox, respectively. These techniques will be useful to rapidly assess the expression of the cytosolic components, p47phox and p67phox, and represents important secondary screening tests for CGD.

Abstract
AbstractThe method for the direct measurement of subcritical crack growth in silica optical fiber with 125μm in diameter was developed. The obtained crack velocity da/dt as a function of stress intensity factor KI was expressed by means of log da/dt vs log KI linear relation with slope n. The obtained value of n showed 22.6 (25 °C,60%r.h.) with small standard deviation 0.7. These results indicate that the postulated crack growth law used for the lifetime prediction is valid and the present approach can solve the problem in the conventional method for evaluating the value of n where the evaluated value has been widely scattered.

Abstract
OBJECTIVES We evaluated the efficacy of perioperative administration of steroid and erythromycin in surgery for lung cancer complicated with interstitial pneumonia (IP) to prevent postoperative acute exacerbation. PATIENTS AND METHODS We operated on 21 lung cancer patients with IP for 10 years. The patients were given 400 mg of erythromycin over 1 week before surgery and re-administered on the 1st operative day. The patients were also given 125 mg of methylprednisolone intravenously just before operation and continued until the 2nd operative day. RESULTS Lobectomy was performed in 16, segmentectomy or partial resection in 2 each, and completion pneumonectomy in 1. Three patients developed acute exacerbation of IP, but it occurred after the re-operation due to postoperative complications in 2. We experienced no operative death within 30 days, however, 2 died during the hospital stay due to multiple organ failure and sepsis. Seven of 21 patients had postoperative complications; air leakage over 1 week in 4, arrhythmia in 3, and atelectasis, postoperative bleeding, and pneumonia in 1 each, the morbidity rate was 33%. CONCLUSIONS We conclude that the administration of steroid and erythromycin in surgery for lung cancer with IP was suspected the usefulness to prevent a postoperative acute exacerbation of IP.

Abstract
Zinc selenide nanoparticles (ZnSe NPs) were synthesized in the cavity of the cage-shaped protein apoferritin by designing a slow chemical reaction system, which employs tetraaminezinc ion and selenourea. The chemical synthesis of ZnSe NPs was realized in a spatially selective manner from an aqueous solution, and ZnSe cores were formed in almost all apoferritin cavities with little bulk precipitation. Three factors are found to be important for ZnSe NP synthesis in the apoferritin cavity: (1) the threefold channel, which selectively introduces zinc ion into the apoferritin cavity, (2) the apoferritin internal potential, which favors zinc ion accumulation in the cavity, and (3) the nucleation site, which nucleates ZnSe inside the cavity. The characterization of the synthesized ZnSe NPs by X-ray powder diffraction and energy-dispersive spectrometry revealed that the synthesized NPs are a collection of cubic ZnSe polycrystals. It was shown that the 500 degrees C heat treatment for 1 h under nitrogen gas transformed the polycrystalline ZnSe core into a single crystal, and single-crystal ZnSe NPs free of protein were obtained.

Abstract
This minireview summarizes the syntheses of various purinenucleotide analogues and their effects on microtubule (Mt) assembly. 27 analogues were so far synthesized and, together with 3 analogues commercially available (ITP, XTP and dGTP), their effects on Microtubule assembly were investigated. The positions C2, C6, C8, and ribose moiety of purine nucleotides were modified or substituted. It was found that the microenvironments of the purine base and ribose moiety are important for the nucleotides to support Mt assembly. Introduction of amino group into position C2 of ATP, formation of 2-amino ATP, caused Mt assembly substantially. 2-Amino deoxy ATP and deoxy GTP are more potent than GTP in supporting assembly. The introduction of reactive thiol group into C6 (6-SH-GTP) largely reduces the activity of the analogue to support assembly. However, sequestering reactivity of the thiol group by association with methyl group largely recovers the ability of the analogue to promote assembly. Free rotation of the glycosidic linkage was found to be also innevitable in promoting assembly, as the introduction of sulfur atom between C8 of the purine base and C2' of the ribose moiety (formation of 8,2'-S-cyclo purine nucleotides) caused total inhibition. Purinenucleoside triphosphate supports assembly better than GTP but the deoxy-type analogues are totally inhibitory. 2-Amino-8-hydroxy ATP and other analogues support assembly much better than does GTP. However, their diphosphate analogues are totally incapable of supporting assembly. Introduction of a bulky fluorescent probes into C3' can be made to visualize the fluorescent signal in assembled Mts. Together with the suggestions proposed from electron chrystallography of zinc-induced tubulin sheets, interactions of the purine base and ribose moieties with surrounding amino acid residues are discussed.

Abstract
This study was aimed to demonstrate the regeneration of skeletal muscle fibers in the stroma reaction during tumor invasion, using the rat model of tongue carcinoma. By oral administration of 4-nitroquinoline N-oxide, squamous cell carcinoma (SCC) appeared in the epithelium, and deeply invaded the muscular layer, inducing the stroma reaction around the tumor. Regenerating muscle fibers, characterized by the immature profiles of sparse myofibrils, centrally disposed multi-nuclei, and abundant mitochondria, were extended from the surrounding normal muscles into the stroma. By immunohistochemistry, some of them expressed BF-45, a marker for an early stage of myodifferentiation, similar to the regenerating muscle fibers in the bupivacaine hydrochloride-induced injury. They were closely associated with the stromal components such as ED-1-positive macrophages, alpha-smooth muscle actin-positive myofibroblasts, and factor VIII-related antigen-positive vascular endothelial cells, suggesting the roles of their interactions in muscle regeneration. Immature muscle fibers were usually devoid of acetylcholinesterase-positive endplates on them, but some were reinnervated by the terminal axons. The present results indicate that skeletal muscle regeneration is induced in association with the stroma reaction during SCC invasion in the tongue.

Abstract
We investigated the effects of SMP-500, a novel acyl-CoA:cholesterol acyltransferase (ACAT) inhibitor, on ACAT activities in the liver and intestine, and in macrophages. We measured its effects on the serum cholesterol levels and hepatic cholesterol content in mice, rabbits and hamsters. SMP-500 inhibited ACAT activities in rabbit liver and small intestine microsomes with IC(50) values of 72 and 84 nmol/l, respectively, and acted as a competitive inhibitor of rabbit liver ACAT. SMP-500 potently inhibited cholesterol esterification in rat peritoneal macrophages (IC(50) = 15 nmol/l). In high-fat and high-cholesterol diet-fed mice and in high-cholesterol diet-fed rabbits, SMP-500 reduced the serum cholesterol levels and the hepatic cholesterol content. SMP-500 also reduced the serum and hepatic cholesterol in normal chow-fed hamsters in a dose-dependent manner. In all the animal models, SMP-500 reduced the hepatic free cholesterol content as well as the total and esterified cholesterol. Administered orally, SMP-500 had a direct inhibitory effect on hepatic ACAT activity. These results indicate that SMP-500 is a potent and competitive ACAT inhibitor and may have a therapeutic potential for treating hypercholesterolemia and atherosclerosis.
