Abstract
49,XXXYY is an extremely rare sex chromosomal aneuploidy (SCA), with only seven cases reported worldwide to date. Among these cases, only three have been documented into adulthood. Moreover, no cases of 49,XXXYY have been reported in Japan. This SCA has been identified in two scenarios: in vitro fertilization and abortion. Similar to 47,XXY, this aneuploidy is a type of Klinefelter syndrome. Aneuploidy of the X chromosome can lead to various progressive complications due to excess X chromosomes. Herein, we present the case of a Japanese man with 49,XXXYY. He exhibited developmental delays and external genitalia abnormalities since early infancy but was not closely monitored for these symptoms until the age of 3 years old. At that time, a chromosome test revealed his karyotype to be 49,XXXYY. Subsequent examinations were conducted due to various symptoms, including delayed motor development, intellectual disability, facial dysmorphisms, forearm deformities, hip dysplasia, cryptorchidism, micropenis, primary hypogonadism, and essential tremor. Since reaching puberty, he has undergone testosterone replacement therapy for primary hypogonadism, experiencing no complications related to androgen deficiency to date. He has maintained normal lipid and glucose metabolism, as well as bone density, for a prolonged period. There are no other reports on the long-term effects of testosterone treatment for the SCA. Appropriate testosterone replacement therapy is recommended for individuals with 49,XXXYY to prevent complications. This report will contribute to an enhanced understanding of the 49,XXXYY phenotype, aiding in the diagnosis, treatment, and genetic counseling of future cases.

Abstract
Responses to a sensory stimulus are inhibited by a preceding stimulus; if the two stimuli are identical, paired-pulse suppression (PPS) occurs; if the preceding stimulus is too weak to reliably elicit the target response, prepulse inhibition (PPI) occurs. PPS and PPI represent excitability changes in neural circuits induced by the first stimulus, but involve different mechanisms and are impaired in different diseases, e.g., impaired PPS in schizophrenia and Alzheimer's disease and impaired PPI in schizophrenia and movement disorders. Therefore, these measures provide information on several inhibitory mechanisms that may have roles in clinical conditions. In the present study, PPS and PPI of the auditory change-related cortical response were examined to establish normative data on healthy subjects (35 females and 32 males, aged 19-70 years). We also investigated the effects of age and sex on PPS and PPI to clarify whether these variables need to be considered as biases. The test response was elicited by an abrupt increase in sound pressure in a continuous sound and was recorded by electroencephalography. In the PPS experiment, the two change stimuli to elicit the cortical response were a 15-dB increase from the background of 65 dB separated by 600 ms. In the PPI experiment, the prepulse and test stimuli were 2- and 10-dB increases, respectively, with an interval of 50 ms. The results obtained showed that sex exerted similar effects on the two measures, with females having stronger test responses and weaker inhibition. On the other hand, age exerted different effects: aging correlated with stronger test responses and weaker inhibition in the PPS experiment, but had no effects in the PPI experiment. The present results suggest age and sex biases in addition to normative data on PPS and PPI of auditory change-related potentials. PPS and PPI, as well as other similar paradigms, such as P50 gating, may have different and common mechanisms. Collectively, they may provide insights into the pathophysiologies of diseases with impaired inhibitory function.

Abstract
The last proton bound calcium isotope ^{35}Ca has been studied for the first time, using the ^{37}Ca(p,t)^{35}Ca two neutron transfer reaction. The radioactive ^{37}Ca nuclei, produced by the LISE spectrometer at GANIL, interacted with the protons of the liquid hydrogen target CRYPTA, to produce tritons t that were detected in the MUST2 detector array, in coincidence with the heavy residues Ca or Ar. The atomic mass of ^{35}Ca and the energy of its first 3/2^{+} state are reported. A large N=16 gap of 4.61(11) MeV is deduced from the mass measurement, which together with other measured properties, makes ^{36}Ca a doubly magic nucleus. The N=16 shell gaps in ^{36}Ca and ^{24}O are of similar amplitude, at both edges of the valley of stability. This feature is discussed in terms of nuclear forces involved, within state-of-the-art shell model calculations. Even though the global agreement with data is quite convincing, the calculations underestimate the size of the N=16 gap in ^{36}Ca by 840 keV.

Abstract
We report on the first proton-induced single proton- and neutron-removal reactions from the neutron-deficient ^{14}O nucleus with large Fermi-surface asymmetry S_{n}-S_{p}=18.6 MeV at ∼100 MeV/nucleon, a widely used energy regime for rare-isotope studies. The measured inclusive cross sections and parallel momentum distributions of the ^{13}N and ^{13}O residues are compared to the state-of-the-art reaction models, with nuclear structure inputs from many-body shell-model calculations. Our results provide the first quantitative contributions of multiple reaction mechanisms including the quasifree knockout, inelastic scattering, and nucleon transfer processes. It is shown that the inelastic scattering and nucleon transfer, usually neglected at such energy regime, contribute about 50% and 30% to the loosely bound proton and deeply bound neutron removal, respectively. These multiple reaction mechanisms should be considered in analyses of inclusive one-nucleon removal cross sections measured at intermediate energies for quantitative investigation of single-particle strengths and correlations in atomic nuclei.

Abstract
OBJECTIVES Glycocalyx lines the vascular intraluminal space that regulates fluid movement between the intra- and extra-vascular compartments. The depletion of glycocalyx (GCX) is associated with leukocyte accumulation, possibly causing the endothelial cells to become hyperpermeable in various organs, including oral tissues. Whether neutrophils or macrophages are responsible for developing interstitial edema remains controversial. We explored the pathophysiological mechanism of interstitial edema by examining the role of reactive neutrophils and macrophages and their interactions with GCX. METHODS An anti-MHC class I antibody was administered intravenously to male BALB/c mice to induce pulmonary edema. Pulmonary edema was evaluated by measuring the lung wet-to-dry weight ratio. Changes in the GCX were evaluated by electron microscopy and measurements of the serum level of soluble syndecan-1. Heparin sulfate was administered to examine its protective effect on the GCX. The macrophages were depleted using clodronate to examine their role in developing edema. RESULTS The GCX degradation induced by the anti-MHC class I antibody was accompanied by increased serum syndecan-1 and heparan sulfate levels. Macrophage depletion inhibited the development of pulmonary edema, and the administration of supplemental heparin suppressed the edema. CONCLUSIONS We demonstrated that the degradation of the GCX induced by the anti-MHC class I antibody was suppressed by macrophage depletion. These results suggest that macrophages may play a key role in interstitial edema. Heparin inhibited both the degradation of the GCX and interstitial edema. This study's results may be extrapolated to develop an interventional strategy for inhibiting interstitial edema in various organs.

Abstract
The atomic masses of ^{55}Sc, ^{56,58}Ti, and ^{56-59}V have been determined using the high-precision multireflection time-of-flight technique. The radioisotopes have been produced at RIKEN's Radioactive Isotope Beam Factory (RIBF) and delivered to the novel designed gas cell and multireflection system, which has been recently commissioned downstream of the ZeroDegree spectrometer following the BigRIPS separator. For ^{56,58}Ti and ^{56-59}V, the mass uncertainties have been reduced down to the order of 10 keV, shedding new light on the N=34 shell effect in Ti and V isotopes by the first high-precision mass measurements of the critical species ^{58}Ti and ^{59}V. With the new precision achieved, we reveal the nonexistence of the N=34 empirical two-neutron shell gaps for Ti and V, and the enhanced energy gap above the occupied νp_{3/2} orbit is identified as a feature unique to Ca. We perform new Monte Carlo shell model calculations including the νd_{5/2} and νg_{9/2} orbits and compare the results with conventional shell model calculations, which exclude the νg_{9/2} and the νd_{5/2} orbits. The comparison indicates that the shell gap reduction in Ti is related to a partial occupation of the higher orbitals for the outer two valence neutrons at N=34.

Abstract
Detailed spectroscopy of the neutron-deficient nucleus ^{36}Ca was obtained up to 9 MeV using the ^{37}Ca(p,d)^{36}Ca and the ^{38}Ca(p,t)^{36}Ca transfer reactions. The radioactive nuclei, produced by the LISE spectrometer at GANIL, interacted with the protons of the liquid hydrogen target CRYPTA, to produce light ejectiles (the deuteron d or triton t) that were detected in the MUST2 detector array, in coincidence with the heavy residues identified by a zero-degree detection system. Our main findings are (i) a similar shift in energy for the 1_{1}^{+} and 2_{1}^{+} states by about -250 keV, as compared with the mirror nucleus ^{36}S; (ii) the discovery of an intruder 0_{2}^{+} state at 2.83(13) MeV, which appears below the first 2^{+} state, in contradiction with the situation in ^{36}S; and (iii) a tentative 0_{3}^{+} state at 4.83(17) MeV, proposed to exhibit a bubble structure with two neutron vacancies in the 2s_{1/2} orbit. The inversion between the 0_{2}^{+} and 2_{1}^{+} states is due to the large mirror energy difference (MED) of -516(130) keV for the former. This feature is reproduced by shell model calculations, using the sd-pf valence space, predicting an almost pure intruder nature for the 0_{2}^{+} state, with two protons (neutrons) being excited across the Z=20 magic closure in ^{36}Ca (^{36}S). This mirror system has the largest MEDs ever observed, if one excludes the few cases induced by the effect of the continuum.

Abstract
Laos, a mountainous and landlocked country located in Southeast Asia, has the highest percentage of people using insects as food in the world. Lao people obtain edible insects through harvesting in the natural environment and purchasing at food markets. There has been no comprehensive survey about sales of insects at food markets in the wider areas, and our understanding of sales of insects in Laos is limited. Our study aims to identify environmental factors affecting the sales and the diversity of edible insects sold at food markets in Laos. We visited 37 and 55 markets, during the dry and rainy seasons respectively, in northern Laos to record species of sold insects. We then analyzed the correlations between insect sales and three potential factors (seasons, provinces, and urbanization indices around the markets). There was no significant difference in the percentage of markets selling insects between in the dry and rainy seasons; 40–50% of the markets sold insects in both seasons. The composition of sold insects differed between in the dry and rainy seasons, which reflects the seasonality and life history of each insect species. There tended to be more groups of insects for sale in the Vientiane capital than in the other provinces in both seasons. This trend may reflect that it is more difficult to obtain edible insects through wild harvesting in highly urbanized Vientiane capital than in the other provinces, and the commercial demand for insects is increasing. This possibility is directly supported by the positive correlation between the urbanization index and the insect sales in the rainy season. Laos has recently undergone rapid urbanization, particularly in the Vientiane capital, and we predict that commercial demand for edible insects will be much higher in the Vientiane capital and the urbanized cities in the future.

Abstract
We present an experimental method to generate quasiperpendicular supercritical magnetized collisionless shocks. In our experiment, ambient nitrogen (N) plasma is at rest and well magnetized, and it has uniform mass density. The plasma is pushed by laser-driven ablation aluminum (Al) plasma. Streaked optical pyrometry and spatially resolved laser collective Thomson scattering clarify structures of plasma density and temperatures, which are compared with one-dimensional particle-in-cell simulations. It is indicated that just after the laser irradiation, the Al plasma is magnetized by a self-generated Biermann battery field, and the plasma slaps the incident N plasma. The compressed external field in the N plasma reflects N ions, leading to counterstreaming magnetized N flows. Namely, we identify the edge of the reflected N ions. Such interacting plasmas form a magnetized collisionless shock.

Abstract
Many neutron star properties, such as the proton fraction, reflect the symmetry energy contributions to the equation of state that dominate when neutron and proton densities differ strongly. To constrain these contributions at suprasaturation densities, we measure the spectra of charged pions produced by colliding rare isotope tin (Sn) beams with isotopically enriched Sn targets. Using ratios of the charged pion spectra measured at high transverse momenta, we deduce the slope of the symmetry energy to be 42<L<117 MeV. This value is slightly lower but consistent with the L values deduced from a recent measurement of the neutron skin thickness of ^{208}Pb.

Abstract
Lipopolysaccharide-responsive beige-like anchor (LRBA) deficiency is a subtype of common variable immune deficiency (CVID). Numerous case reports and cohort studies have described a broad spectrum of clinical manifestations and variable disease phenotypes, including immune dysregulation, enteropathy, and recurrent infections. Although LRBA deficiency is an autosomal recessive primary immunodeficiency resulting in a phenotype similar to CVID, it is a monogenic disease and separate from CVID. Recently, in a report of monogenic primary immunodeficiency disorder associated with CVID and autoimmunity, the most common mutated gene was LRBA. We report the case of a girl who presented with fulminant type 1 diabetes at age 7 months. She later experienced recurrent bacterial infections with neutropenia and idiopathic thrombocytopenic purpura. Clinical genome sequencing revealed compound heterozygosity of the LRBA gene, which bore two novel mutations. A genetic basis should be considered in the differential diagnosis for very young patients with fulminant autoimmunity, and the diagnostic work-up should include evaluation of markers of immunodeficiency.

Abstract
BACKGROUND The paratenon is a sheath-like connective tissue that allows the tendon to move with minimal friction. The careful removal of the paratenon along the cruciate ligaments is a critical step of knee surgery. Thus, orthopedic surgeons and interventional radiologists consider the paratenon as a basic anatomical tissue along a ligament, not along a tendon. MATERIALS AND METHODS We performed macroscopic and histological observations of cruciate ligament-associated paratenons in 43 human fetuses. RESULTS This tissue usually had a thick armor-like appearance that was distant from the infrapatellar fat pad. The anterior cruciate ligament, rather than the posterior ligament, was deeply embedded in the paratenon. The paratenon contained abundant arteries and veins and, at and near the crossing between the cruciate ligaments, had a well-developed venous plexus. Notably, there were abundant fused veins in the paratenon venous plexus, and prenatal knee movements (especially rotation) seemed to restrict its blood supply, leading to the development of a large cavity by way of advancing fusion of veins in the degenerating plexus. This unique manner of cavitation likely expanded the joint cavity. CONCLUSIONS Differences in knee movements in utero seemed to cause differences in the thickness of the paratenon among fetuses. New-borns might have limited knee flexion due to a mass-effect of the thick paratenon around the cruciate ligaments. A slight twisting or rotation at the knee may help to release the knee, because it can break the fetal paratenon and accelerate cavitation.

Abstract
Twenty-one two-proton knockout (p,3p) cross sections were measured from neutron-rich nuclei at ∼250 MeV/nucleon in inverse kinematics. The angular distribution of the three emitted protons was determined for the first time, demonstrating that the (p,3p) kinematics are consistent with two sequential proton-proton collisions within the projectile nucleus. Ratios of (p,3p) over (p,2p) inclusive cross sections follow the trend of other many-nucleon removal reactions, further reinforcing the sequential nature of (p,3p) in neutron-rich nuclei.

Abstract
We report the measurement of reaction cross sections (σ_{R}^{ex}) of ^{27,29}F with a carbon target at RIKEN. The unexpectedly large σ_{R}^{ex} and derived matter radius identify ^{29}F as the heaviest two-neutron Borromean halo to date. The halo is attributed to neutrons occupying the 2p_{3/2} orbital, thereby vanishing the shell closure associated with the neutron number N=20. The results are explained by state-of-the-art shell model calculations. Coupled-cluster computations based on effective field theories of the strong nuclear force describe the matter radius of ^{27}F but are challenged for ^{29}F.

Abstract
Background:Similar to biologic disease-modifying anti-rheumatic drugs, the association between Janus kinase (JAK) inhibitors and infection is particularly interesting. The incidence of herpes zoster (HZ) among patients treated with JAK inhibitors is twofold to threefold higher in several regions of Asia (e.g., Japan and Korea) as compared with that observed in North America and Western Europe [1].Objectives:To evaluate the characteristics of patients who developed HZ during baricitinib treatment using real-world, multicenter, clinical data for Japanese population.Methods:The study enrolled 97 patients with rheumatoid arthritis (RA) who were treated with baricitinib therapy (68 biologic-naïve patients and 29 biologic-experienced patients) were enrolled in the study (observation period: 2–27 months). The severity of HZ infection was determined based on the extent of the rash and the presence or absence of organ damage. We evaluated the characteristics and clinical courses of patients who developed HZ.Results:Eight patients with HZ. The incidence ratio (IR) was 8.2 per patient-year. Patient data are described in Table 1 and Table 2. The IR was a little higher than that reported in clinical trials [2], which could be attributed to the high average age (i.e., 67.3 years) of the patients in this study. It was reported that adverse events occurred more frequently in elderly patients aged ≥65 years compared with younger patients [3]. The period from baricitinib administration to the onset of HZ varied between 2 months and 16 months. It is suggested that HZ may develop at any time during baricitinib therapy. There were no distinctive patient characteristics, except for age, at the time of initial baricitinib administration between patients who developed HZ and those who did not.Table 2.Response rates of non-medical Switch from Cellcept to MyforticCase- No.Age (years)Time (years) from RA onsetGenderFemale:FMale: M)BMIBari dose (mg/d)PSL(mg/d)MTX (mg/w)HZ historyNumber of prior biologics1741.5F25.64012No226133F19.2206No136111.1F23.64010Yes04730.5M23.3408Yes057421.9F20.9200No06781.2F19.8406No074823.2F24.1448No08795.0F22.422.54No0Table 1.Fatigue in NPSLE and non-NPSLE patients (N = 222)Case No.HZ incidence period after baricitinib administration (months)Priod of baricitinib withdrawal (weeks)Severity(Mild; MilModerate: Mod)1164Mod224Mod3131Mil431Mil586Mod634Mil ~ Mod733Mod820Discontinuation due to pateient’s choiceModNone of the patients had severe symptoms, and none of them experienced organ damage. All patients were cured with anti-viral agents. It should be noted that patients who had a history of HZ had milder symptoms than those who had no history of HZ. We noted an interesting finding in one patient (case 2). The half-life of baricitinib in the blood was very short (about 6 hours), and it is reported that the drug is almost fully excreted from the body 24 hours after its administration [4]. However, this patient developed an incidence of HZ at 17 days after the withdrawal of baricitinib for surgery management. Cells may take longer time to regain their original immune status even after excretion of the drug, especially, during intense stress such as in cases of surgical invasion.Conclusion:The HZ risk in Japanese patients with RA treated with baricitinib in real-world practice was high, especially in elderly patients. It is notable that HZ events were nonserious and that patients could restart baricitinib treatment after healing with antiviral therapy, for the most part.References:[1]Taylor PC et al.

Abstract
Background:Baricitinib (bari) is an oral Janus kinase 1 (JAK1)/JAK2 selective inhibitor that has demonstrated good efficacy in patients with rheumatoid arthritis (RA) and adequate response to conventional synthetic (cs) DMARDs in some clinical trials [1,2]. We report the efficacy and safety of bari within 24 weeks in real-world clinical data at EULAR2019.Objectives:To evaluate the radiographic progression of structural joint damage at 48 weeks in Japanese patients with RA in real-world multicenter clinical data.Methods:We included 53 Japanese patients with RA who showed an inadequate response to csDMARDs or biologic (b) DMARDs. Patients were scheduled to receive a once-daily dose of 4 or 2 mg/day bari as monotherapy or in combination with other csDMARDs. We divided the patients into two groups: those treated with 2 mg/day of bari (2mg-group; n = 27) and those treated with 4 mg/day of bari (4-mg group; n = 26) throughout the observation period. Patients were allowed to decrease their predonisolone and csDMARDs combined with bari treatment if their disease activity improved. First, we evaluated changes in CDAI and HAQ-DI after 48 weeks. Second, we evaluated the change in the van der Heijdge modified total sharp score (ΔmTSS), erosion score (ΔERN), and joint space narrowing score (ΔJSN). In addition, we assessed predictors for suppression of joint destruction at 48 weeks after bari treatment.Results:The baseline characteristics of the patients were as summarized in Table 1. There were no significant differences in any items. CDAI scores significantly improved 4 weeks after the treatment. This tendency continued until the final evaluation (Table 2). At 48 weeks, remission and low disease activity rates were 37.0% and 74.1% in the 2-mg group and 38.4% and 76.9% in the 4-mg group, respectively. Structural remission (mTSS ≤ 0.5) was noted in 21 patients (80.8%) and 21 patients (77.8%) in 4-mg group and 2-mg group, respectively (Figure). Mean scores (ΔmTSS, ΔERN, and ΔJSN) of all patients in the 2-mg group and 4-mg groups were (0.26, 0.15, and 0.11), (0.30, 0.17, and 0.13) and (0.23, 0.13, and 0.10), respectively (Figure). There were no significant differences in ΔmTSS scores between the two groups. A matrix metalloproteinase-3 score within the standard value at 12 weeks after the treatment was associated with a predictor for suppression of joint destruction at 48 weeks (logistic regression analysis; odds ratio = 11.6, 95% confidence interval: 1.5–112.4,P= 0.020).Table 1.Characteristics of patients at baricitinib initiation2mg-group (n=27)4mg-group (n=26)p-valueAge (years)69.1 (12.0)65.6 (10.3)0.20Gender, female, n (%)19 (73.1)23 (85.2)0.28Disease duration (years),9.7 (10.4)5.7 (7.4)0.23Prior use of biologics, (0/1/2/3)(18/6/2/1)(18/2/5/1)------MTX (mg/week),4.5 (3.7)6.5 (4.29)0.08PSL (mg/day)1.0 (1.9)1.2 (1.8)0.49RF, U/ml254 (372)134 (222)0.21ACPA, U/m152 (176)133 (301)0.45MMP-3196 (220)215 (221)0.43Table 2.Serial change of clinical assessment2mg-groupBaseline4 week12 week24 week48 weekCDAI22.5 (9.2)7.4 (7.7)6.7 (6.9)6.9 (6.8)6.9 (6.8)HAQ-DI0.88 (0.51)0.45 (0.47)0.53 (0.58)0.56 (0.56)0.56 (0.56)MMP-3196 (221)98.9 (62.2)115 (164)106 (78)106 (78)4mg-groupBaseline4 week12 week24 week48 weekCDAI24.4 (9.7)9.4 (5.7)8.6 (6.3)6.7 (8.6)6.8 (8.6)HAQ-DI1.01 (0.51)0.58 (0.48)0.54 (0.60)0.45 (0.49)0.44 (0.45)MMP-3216 (222)99 (62)101 (123)89 (72)95 (81)Conclusion:The data showed that bari has a favorable effect on the radiographic progression of structural joint damage regardless of its dose in a real-world clinical setting.

Abstract
Background:Baricitinib (bari) is an oral Janus kinase (JAK) 1/JAK2 selective inhibitor that has shown good efficacy in patients with RA and adequate response to conventional synthetic DMARDs in some clinical trials [1,2]. However, concerning the high cost and long-term safety related to the inhibition of particular molecules, we would like to discontinue bari after achieving long low disease activity (LDA).Objectives:To evaluate the clinical outcomes in patients with RA who discontinued bari after achieving LDA for 24 weeks in real-world multicenter clinical data.Methods:Japanese 67 patients with RA who show an inadequate response to csDMARDs or bDMARDs were scheduled to receive bari 4 or 2 mg/day once daily dose as a monotherapy or in combination with other csDMARDs. We included 51 patients who achieved and maintained LDA at least for 24 weeks after baricitinib therapy. They were allowed to decrease baricitinib after discontinuation of prednisolone. Bari was either discontinued or continued after study enrolment. The decision of discontinuation and continuation of baricitinib was determined based on patient-physician decision making with informed consent. We divided patients into two groups: a discontinuation group (D group; n = 23) and a continuation group (C group; n = 28). We evaluated the proportion of patients who remained LDA for 24 weeks in both groups. Clinical outcomes including Clinical Disease Activity Index (CDAI), and HAQ-DI were compared between both groups. The last observational carried forward method was used for patients who could not discontinue baricitinib due to flare before 24 weeks. In D group, patients were treated with re-initiation of bari or initiation of the other DMARDs in the event of flare. We investigated the serial changes of patients treated with re-initiation of bari in CDAI after flare.Results:The baseline characteristics of the patients are summarized in Table. The titer of RF was lower in D group than that in C group. There were no significant differences in any other items. Ten of 23 (43.4%) in D group remained bari-free without disease activity flare. Serial changes of CDAI were summarized in Figure. CDAI in D group significantly increased from 3.6 at baseline to 9.8 at last observation. LDA rates in C group were 92.9% at last observation. CDAI in C group did not change throughout the follow-up period. CDAI at last observation was higher in D group than that in C group. HAQ-DI in D group changed from 0.28 at baseline to 0.45 at last observation. There was no significant change in HAQ-DI between both groups (P = 0.28). In D group, rescue by re-administration of bari or other DMARDs induced improvement, reducing CDAI from 15.5 at disease flare to 6.8. Especially, all patients treated with re-initiation of bari resulted in re-introduction of LDA in this study.Table.Characteristics of patients at baricitinib initiationD group (n=23)C group (n=28)p-valueAge (years)66.9 (8.6)67.9 (12.7)0.31Gender, female, n (%)6 (73.9)24 (85.7)0.49Disease duration (years)7.6 (10.3)8.3 (9.9)0.37Prior use of biologics, n (0/1/2/≥3)(21/2/0/0)(17/6/4/1)------MTX (mg/w)5.5 (3.8)4.9 (4.3)0.62PSL (mg/d)1.4 (1.9)0.9 (0.9)0.51RF, U/ml99 (141)187 (214)0.04ACPA, U/ml135 (173)194 (214)0.11CDAI24.4 (9.2)22.5 (9.7)0.36HAQ-DI0.83 (0.49)0.83 (0.52)0.98Conclusion:It was possible to discontinue bari without flare in about 43% of patients with RA.

Abstract
OBJECTIVES von Willebrand factor (vWF) has prognostic value in patients with heart failure (HF) and in those with liver disease. Liver congestion, due to right-sided HF (RHF), is one of the major clinical pathophysiologic manifestations in adults with congenital heart disease (ACHD). The present study's purpose was to clarify the prognostic value of plasma levels of vWF antigen (vWF:Ag) in ACHD. METHODS We measured vWF:Ag (%) in 382 consecutive patients (20 unrepaired cyanotic ACHD, 172 Fontan patients and 190 ACHD after biventricular repair) and compared the results with the clinical profiles and prognosis. RESULTS The plasma vWF:Ag level was 130±53 (normal range: 55%-190%), and 48 patients (13%) showed high levels of vWF:Ag (≥190%). Older age, Fontan circulation, higher central venous pressure, lower arterial oxygen saturation and lower plasma levels of albumin were independently associated with high log (vWF:Ag) (p<0.05-0.0001). During the follow-up of 2.4±1.4 years, 15 patients died. High log (vWF:Ag) predicted the all-cause mortality (HR 1.63 per 0.1, 95% CI 1.40 to 1.96, p<0.0001). Specifically, patients with high vWF:Ag (≥165%) had a substantially higher risk of all-cause mortality (HR 56.4, 95% CI 11.4 to 1020, p<0.0001), and this prognostic value was independent of plasma levels of brain-type natriuretic peptide. CONCLUSIONS High vWF:Ag may reflect RHF severity and related liver dysfunction with a strong prognostic value of all-cause mortality in ACHD. Thus, vWF:Ag might be an excellent biomarker for monitoring ACHD with RHF.

Abstract
BACKGROUND Fontan patients exhibit a high prevalence of abnormal glucose metabolism (AGM). We aimed to characterize AGM and clarify its association with Fontan pathophysiology. METHODS We prospectively evaluated AGM with plasma glucose dynamics [mg/dL; fasting glucose (FPG), and maximum glucose increase (PG-spike)] during oral glucose tolerance test and hemoglobin A1c (HbA1c) in 276 consecutive Fontan patients (aged 19 ± 7 years). Of these, 176 patients had serial AGM assessments with a mean interval of 6.5 years. RESULTS Initial analysis revealed a high prevalence of impaired glucose tolerance (38.4%) and diabetes mellitus (DM) (4.7%), and positive family history, high HbA1c, and high central venous pressure independently predicted presence of DM. HbA1c was independently determined by hypersplenism and presence of DM (P < .05). Serial assessments revealed an increased PG-spike and a decreased HbA1c (P < .001 for both). Prevalence of DM increased (6.3% to 10.3%), and positive family history, high liver enzymes, and AGM predicted new onset of DM (P < .05 for all). Twenty-one patients died during 7.1-year follow-up. FPG (P < .01) and PG-spike (P < .05) independently predicted all-cause mortality. Particularly, patients with FPG ≤ 74 and/or PG-spike ≥85 had a mortality rate 8.7 times higher than those without (P = .0129). CONCLUSIONS AGM progressed even in young adult Fontan patients, and HbA1c showed limited predictive value for progression. Oral glucose tolerance test plays important roles in uncovering unique Fontan AGM as well as predicting all-cause mortality.

Abstract
Fifty-five inclusive single nucleon-removal cross sections from medium mass neutron-rich nuclei impinging on a hydrogen target at ∼250 MeV/nucleon are measured at the RIKEN Radioactive Isotope Beam Factory. Systematically higher cross sections are found for proton removal from nuclei with an even number of protons as compared to odd-proton number projectiles for a given neutron separation energy. Neutron removal cross sections display no even-odd splitting, contrary to nuclear cascade model predictions. Both effects are understood through simple considerations of neutron separation energies and bound state level densities originating in pairing correlations in the daughter nuclei. These conclusions are supported by comparison with semimicroscopic model predictions, highlighting the enhanced role of low-lying level densities in nucleon-removal cross sections from loosely bound nuclei.

Abstract
The selective α2A adrenoceptor agonist guanfacine reduces hyperactivity and improves cognitive impairment in patients with attention-deficit/hyperactivity disorder (ADHD). The major mechanisms of guanfacine have been considered to involve activation of postsynaptic α2A adrenoceptor in frontal pyramidal neurons. However, the effects of chronic guanfacine administration on catecholaminergic transmissions associated with the orbitofrontal cortex (OFC) remain unclear. To explore the mechanisms of action of guanfacine on catecholaminergic transmission, the effects of its acute local or sub-chronic systemic administration on catecholamine release within pathways from locus coeruleus (LC) to OFC and reticular thalamic nucleus (RTN), from RTN to mediodorsal thalamic nucleus (MDTN), and from MDTN to OFC were determined using multi-probe microdialysis with ultra-high performance liquid chromatography. Acute OFC local administration of guanfacine did not affect catecholamine release in OFC. Acute LC local and sub-chronic systemic administrations of guanfacine reduced norepinephrine release in LC, OFC and RTN, and also reduced GABA release in MDTN, whereas AMPA-induced (perfusion with AMPA into NDTN) releases of l-glutamate, norepinephrine and dopamine in OFC were enhanced by sub-chronic systemic guanfacine administration. This study identified that catecholaminergic transmission is composed of three pathways: direct noradrenergic and co-releasing catecholaminergic LC-OFC pathways and intermediate LC-OFC (LC-RTN-MDTN-OFC) pathway. We demonstrated the dual actions of guanfacine on catecholaminergic transmission: attenuation of direct noradrenergic LC-OFC transmission at the resting stage and enhancement of direct co-releasing catecholaminergic LC-OFC transmission via GABAergic disinhibition in the intermediate LC-OFC pathway. These dual actions of guanfacine probably contribute to clinical actions of guanfacine against ADHD and its comorbid symptoms. This article is part of the Special Issue entitled 'Current status of the neurobiology of aggression and impulsivity'.

Abstract
SRY-negative 46,XX testicular disorders of sex development (DSD) are very rare conditions. Recently, we identified a novel heterozygous NR5A1 mutation, p.Arg92Trp (c.274C>T, p.R92W), in 2 unrelated cases of 46,XX testicular/ovotesticular DSD. We report the clinical course from infancy to puberty in a Japanese male with SRY-negative 46,XX testicular DSD, carrying this p.Arg92Trp mutation in NR5A1. The patient naturally acquired the development of a penis and pubic hair during puberty. However, hypergonadotropic hypogonadism subsequently developed. More clinical cases will be needed to fully understand the effects of the p.Arg92Trp mutation on the ability to maintain testosterone secretion in 46,XX testicular DSD.

Abstract
Distant metastasis remarkably worsens the prognoses of malignant melanoma patients. Toll-like receptors (TLRs) recognize molecules derived from many types of pathogens and activate the innate intravital immune system. In this study, we examined the effects of R848, a TLR7 ligand, on bone invasion by malignant melanoma cells. Mice underwent transplantation with cells of a malignant melanoma cell line B16F10, and were also administered R848 every three days. Hindlimbs were obtained 13 days after transplantation and invasion of bone marrow by B16F10 cells was evaluated. ELISA was used to determine the concentrations of cytokines in mouse serum and in the culture medium from bone marrow macrophages (BMMs) in the presence or absence of R848. In addition, MTS assays were used to examine the effects of media from BMM cultures on the proliferation of B16F10 cells. The rate of infiltration by B16F10 cells and the area of invasion were significantly reduced with R848 administration. Furthermore, serum levels of IL-6, IL-12, and IFN-γ were significantly increased in mice administered R848, with the same trend observed in the culture medium of BMMs treated with R848. In addition, B16F10 cell proliferation was suppressed by the addition of medium from cultured BMMs treated with R848. Neutralization by antibodies against IL-6, IL-12, and IFN-γ abrogated the suppression of proliferation of B16F10 cells by culture medium from BMMs treated with R848. Our results suggest that R848 drives the production of IL-6, IL-12, and IFN-γ in BMMs, which reduces proliferation and bone invasion by B16F10 cells.

Abstract
In-beam γ-ray spectroscopy of ^{79}Cu is performed at the Radioactive Isotope Beam Factory of RIKEN. The nucleus of interest is produced through proton knockout from a ^{80}Zn beam at 270 MeV/nucleon. The level scheme up to 4.6 MeV is established for the first time and the results are compared to Monte Carlo shell-model calculations. We do not observe significant knockout feeding to the excited states below 2.2 MeV, which indicates that the Z=28 gap at N=50 remains large. The results show that the ^{79}Cu nucleus can be described in terms of a valence proton outside a ^{78}Ni core, implying the magic character of the latter.

Abstract
Rac1, a member of the small Rho GTPase family, plays multiple cellular roles. Studies of mice conditionally lacking Rac1 have revealed essential roles for Rac1 in various tissues, including cartilage and limb mesenchyme, where Rac1 loss produces dwarfism and long bone shortening. To gain further insight into the role of Rac1 in skeletal development, we have used transgenic mouse lines to express a constitutively active (ca) Rac1 mutant protein in a Cre recombinase-dependent manner. Overexpression of caRac1 in limb bud mesenchyme or chondrocytes leads to reduced body weight and shorter bones compared with control mice. Histological analysis of growth plates showed that caRac1;Col2-Cre mice displayed ectopic hypertrophic chondrocytes in the proliferative zone and enlarged hypertrophic zones. These mice also displayed a reduced proportion of proliferating cell nuclear antigen-positive cells in the proliferative zone and nuclear β-catenin localization in the ectopic hypertrophic chondrocytes. Importantly, overexpression of caRac1 partially rescued the phenotypes of Rac1fl/fl;Col2-Cre and Rac1fl/fl;Prx1-Cre conditional knockout mice, including body weight, bone length, and growth plate disorganization. These results suggest that tight regulation of Rac1 activity is necessary for normal cartilage development.

Abstract
In endochondral ossification, growth of bones occurs at their growth plate cartilage. While it is known that nitric oxide (NO) synthases are required for proliferation of chondrocytes in growth plate cartilage and growth of bones, the precise mechanism by which NO facilitates these process has not been clarified yet. C-type natriuretic peptide (CNP) also positively regulate elongation of bones through expansion of the growth plate cartilage. Both NO and CNP are known to use cGMP as the second messenger. Recently, 8-nitro-cGMP was identified as a signaling molecule produced in the presence of NO in various types of cells. Here, we found that 8-nitro-cGMP is produced in proliferating chondrocytes in the growth plates, which was enhanced by CNP, in bones cultured ex vivo. In addition, 8-nitro-cGMP promoted bone growth with expansion of the proliferating zone as well as increase in the number of proliferating cells in the growth plates. 8-Nitro-cGMP also promoted the proliferation of chondrocytes in vitro. On the other hand, 8-bromo-cGMP enhanced the growth of bones with expansion of hypertrophic zone of the growth plates without affecting either the width of proliferating zone or proliferation of chondrocytes. These results indicate that 8-nitro-cGMP formed in growth plate cartilage accelerates chondrocyte proliferation and bone growth as a downstream molecule of NO.

Abstract
Leeches belonging to the genus Ozobranchus are ectoparasitic on sea and freshwater turtles. The freshwater species O. jantseanus has been recorded from China and Japan. Ozobranchus jantseanus inhabiting Japan is considered to be a non-indigenous species, because their primary host, the Reeves' pond turtle, Mauremys reevesii, is thought to have been introduced in the last few centuries from adjacent Asian countries. To assess whether the Japanese populations of O. jantseanus were likely to have been introduced, their genetic diversity was investigated using mitochondrial cytochrome c oxidase subunit I sequences. The very low sequence diversity as well as the historical record of this species from Japan suggest that Japanese populations of O. jantseanus may have been artificially introduced along with their host turtles. Molecular phylogenies of COI showed that two marine Ozobranchus species formed a clade together with the freshwater O. jantseanus.

Abstract
Aldosterone synthase is the key rate‐limiting enzyme in adrenal aldosterone production, and induction of its gene (CYP11B2) results in the progression of hypertension. As hypertension is a frequent complication among patients with diabetes, we set out to elucidate the link between diabetes mellitus and hypertension. We examined the effects of high glucose on CYP11B2 expression and aldosterone production using human adrenal H295R cells and a stable H295R cell line expressing a CYP11B2 5′‐flanking region/luciferase cDNA chimeric construct. d‐glucose (d‐glu), but not its enantiomer l‐glucose, dose dependently induced CYP11B2 transcription and mRNA expression. A high concentration (450 mg·dL−1) of d‐glu time dependently induced CYP11B2 transcription and mRNA expression. Moreover, high glucose stimulated secretion of aldosterone into the media. Transient transfection studies using deletion mutants/nerve growth factor‐induced clone B (NGFIB) response element 1 (NBRE‐1) point mutant of CYP11B2 5′‐flanking region revealed that the NBRE‐1 element, known to be activated by transcription factors NGFIB and NURR1, was responsible for the high glucose‐mediated effect. High glucose also induced the mRNA expression of these transcription factors, especially that of NURR1, but NURR1 knockdown using its siRNA did not affect high glucose‐induced CYP11B2 mRNA expression. Taken together, it is speculated that high glucose may induce CYP11B2 transcription via the NBRE‐1 element in its 5′‐flanking region, resulting in the increase in aldosterone production although high glucose‐induced NURR1 is not directly involved in the effect. Additionally, glucose metabolism and calcium channels were found to be involved in the high glucose effect. Our observations suggest one possible explanation for the high incidence of hypertension in patients with diabetes.

Abstract
The effects of retinoids on adrenal aldosterone synthase gene (CYP11B2) expression and aldosterone secretion are still unknown. We therefore examined the effects of nuclear retinoid X receptor (RXR) pan-agonist PA024 on CYP11B2 expression, aldosterone secretion and blood pressure, to elucidate its potential as a novel anti-hypertensive drug. We demonstrated that PA024 significantly suppressed angiotensin II (Ang II)-induced CYP11B2 mRNA expression, promoter activity and aldosterone secretion in human adrenocortical H295R cells. Human CYP11B2 promoter functional analyses using its deletion and point mutants indicated that the suppression of CYP11B2 promoter activity by PA024 was in the region from -1521 (full length) to -106 including the NBRE-1 and the Ad5 elements, and the Ad5 element may be mainly involved in the PA024-mediated suppression. PA024 also significantly suppressed the Ang II-induced mRNA expression of transcription factors NURR1 and NGFIB that bind to and activate the Ad5 element. NURR1 overexpression demonstrated that the decrease of NURR1 expression may contribute to the PA024-mediated suppression of CYP11B2 transcription. PA024 also suppressed the Ang II-induced mRNA expression of StAR, HSD3β2 and CYP21A2, a steroidogenic enzyme group involved in aldosterone biosynthesis. Additionally, the PA024-mediated CYP11B2 transcription suppression was shown to be exerted via RXRα. Moreover, the combination of PPARγ agonist pioglitazone and PA024 caused synergistic suppressive effects on CYP11B2 mRNA expression. Finally, PA024 treatment significantly lowered both the systolic and diastolic blood pressure in Tsukuba hypertensive mice (hRN8-12 x hAG2-5). Thus, RXR pan-agonist PA024 may be a candidate anti-hypertensive drugs that acts via the suppression of aldosterone synthesis and secretion.

Abstract
Although empirical findings have indicated increase in bone fracture risk in type 2 diabetes patients, that has yet to be proven by results obtained at the material level. Here, we report evidence showing nanoscale time-dependent deformation/recovery of in vitro calcified nodules mimicking bone turnover in type 2 diabetes in respect to methylglyoxal (MG)-induced glycation. Nanoindentation test results revealed that calcified nodules cultured with MG did not show adequate dimensional recovery, despite a large creep rate during constant load indentation testing. This lesser recovery is likely based on the linear matrix polymerization network formed by advanced glycation end products (AGEs) as a secondary product of MG. Since elevated serum MG and abnormal bone turnover related to the amount of AGEs are observed in cases of type 2 diabetes, this time-dependent behavior may be one of the factors of the bone fracture mechanism at the material level in affected patients.

Abstract
The level structure of the neutron-rich ^{77}Cu nucleus is investigated through β-delayed γ-ray spectroscopy at the Radioactive Isotope Beam Factory of the RIKEN Nishina Center. Ions of ^{77}Ni are produced by in-flight fission, separated and identified in the BigRIPS fragment separator, and implanted in the WAS3ABi silicon detector array, surrounded by Ge cluster detectors of the EURICA array. A large number of excited states in ^{77}Cu are identified for the first time by correlating γ rays with the β decay of ^{77}Ni, and a level scheme is constructed by utilizing their coincidence relationships. The good agreement between large-scale Monte Carlo shell model calculations and experimental results allows for the evaluation of the single-particle structure near ^{78}Ni and suggests a single-particle nature for both the 5/2_{1}^{-} and 3/2_{1}^{-} states in ^{77}Cu, leading to doubly magic ^{78}Ni.

Abstract
OBJECTIVES There have been several systematic reviews(SRs) on whether periodontal treatment for an individual with both periodontal disease and diabetes can improve diabetes outcomes. The purpose of this investigation was to conduct a systematic review (SR) of previous meta-analyses, and to assess the methodological quality of the SRs examining the effects of periodontal treatment and diabetes. (PROSPERO Registration # CRD 42015023470). STUDY DESIGN We searched five electronic databases and identified previous meta-analyses of randomized controlled trials published through July 2015. In cases where the meta-analysis did not meet our criteria, the meta-analyses were recalculated. General characteristics of each included trial were abstracted, analyzed, and compared. The mean difference, 95% confidence intervals (CIs) and the I2 statistic were abstracted or recalculated. The Assessment of Multiple Systematic Reviews Instrument (AMSTAR) was used to assess methodological quality. RESULTS Of the 475 citations screened, nine systematic reviews were included. In total, 13 meta-analyses included in nine SRs were examined. In comparability analyses, meta-analyses in four SRs did not meet our criteria, and were recalcuated. Of these 13 meta-analyses, 10 suggested significant effects of periodontal treatment on HbA1c improvement. Mean differences found in the 13 meta-analyses ranged from -0.93 to 0.13. AMSTAR assessment revealed six SRs with moderate and three with high overall quality. CONCLUSIONS We can conclude that there is a significant effect of periodontal treatment on improvement of HbA1c in diabetes patients, although the effect size is extremely small. In addition to the small effect size, not all SRs could be considered of high quality.

Abstract
Sucroferric oxyhydroxide (SFOH) is a non-calcium, iron-based phosphate binder indicated for the treatment of hyperphosphatemia in adult dialysis patients. Studies in Japan about the side effects of SFOH treatment indicate that the incidence of diarrhea (25%) is greater while that of constipation (2.9%) is lesser in comparison to that observed upon treatment with an existing phosphate binder. In the present study, the effect of treatment with a combination of the existing phosphate binders and SFOH on the serum phosphorus level and digestive symptoms was observed in hemodialysis patients with hyperphosphatemia, which is untreatable using only the existing phosphate binders. We evaluated the serum phosphorus levels and gastrointestinal symptoms (using the gastrointestinal symptom rating scale) of 6 patients (2 men, 4 women) before and 2, 4, 6, and 8 weeks after continuous administration. The serum phosphorus levels before and 2, 4, 6, and 8 weeks after combination treatment were 7.4±1.0 mg/dL, 5.9±1.3 mg/dL, 5.8±1.5 mg/dL, 5.8±1.4 mg/dL, and 5.8±1.3 mg/dL, respectively, with significant reduction in the levels being observed 2 weeks after administration (p<0.05) and persisting even 8 weeks after continuous administration. The constipation scores before and 2, 4, and 8 weeks after drug administration were 2.39±0.85, 2.34±1.93, 2.56±1.44, and 3.28±2.19, respectively, with no changes observed during the investigation period. The diarrhea scores before and 2, 4, and 8 weeks after drug administration were 2.22±0.91, 2.06±1.16, 1.28±0.39, and 1.06±0.13 respectively. The scores improved significantly, 4 weeks after drug administration (p<0.05), and the improvement persisted, even 8 weeks after continuous administration. Thus, by using a combination of the existing phosphate binders and SFOH, we were able to reduce the serum phosphorus level in patients with hyperphosphatemia, which is untreatable using the existing phosphate binder alone, with no sign of exacerbation of the gastrointestinal symptoms despite a few contradictory case reports.

Abstract
Interferon regulatory factor 8 (Irf8) is a transcription factor that negatively regulates osteoclast differentiation and Irf8 global knockout (Irf8−/−) mice have been shown to have reduced bone volume resulting from increased osteoclast numbers. However, detailed analysis of the functions of Irf8 in osteoclast precursors with a monocyte/macrophage linage is difficult, because the population and properties of hematopoietic cells in Irf8−/− mice are severely altered. Therefore, to clearly elucidate the functions of Irf8 during osteoclastogenesis, we established myeloid cell-specific Irf8 conditional knockout (Irf8fl/fl;Lyz2cre/+) mice. We found that trabecular bone volume in the Irf8fl/fl;Lyz2cre/+ mice was not significantly affected, while exposure to M-CSF and RANKL significantly increased TRAP activity in vitro in osteoclasts that underwent osteoclastogenesis from bone marrow-derived macrophages (BMMs) induced from bone marrow cells (BMCs) of those mice by addition of M-CSF. Our results also showed that expression of Irf8 mRNA and protein in BMMs obtained from Irf8fl/fl;Lyz2cre/+ mice and cultured with M-CSF was reduced. These findings predicted that Lyz2/Lyz2-cre expression is induced when BMCs differentiate into BMMs in cultures with M-CSF. In osteoclast differentiation cultures, Lyz2 was gradually increased by M-CSF during the first 3 days of culture, then rapidly decreased by the addition of RANKL with M-CSF during the next 3 days. Furthermore, BMCs differentiated into osteoclasts while maintaining a low level of Lyz2 expression when cultured simultaneously with both M-CSF and RANKL from the initiation of culture. These findings suggest that Lyz2-cre expression is induced along with differentiation to BMMs by BMCs obtained from Irf8fl/fl;Lyz2cre/+ mice and cultured with M-CSF. In addition, Irf8 was down-regulated by activation of the cre/loxP recombination system in BMMs and osteoclastogenesis was accelerated. Based on our results, we propose the existence in vivo of a new lineage of osteoclast precursors among BMCs, which differentiate into osteoclasts without up-regulation of Lyz2 expression.

Abstract
The extracellular matrix protein nephronectin (Npnt), also called POEM, is considered to play critical roles as an adhesion molecule in development and functions of various tissues, such as the kidneys, liver, and bone. In the present study, we examined the molecular mechanism of Npnt gene expression and found that vitamin D3 (1α,25-dihydroxyvitamin D3,VD 3) strongly enhanced Npnt mRNA expression in MC3T3-E1 cells from a mouse osteoblastic cell line. The VD 3-induced increase in Npnt expression is both time- and dose-dependent and is mediated by the vitamin D receptor (VDR).

Abstract
We present a statistical analysis of the first four seasons from a "second-generation" microlensing survey for extrasolar planets, consisting of near-continuous time coverage of 8 deg2 of the Galactic bulge by the OGLE, MOA, and Wise microlensing surveys. During this period, 224 microlensing events were observed by all three groups. Over 12% of the events showed a deviation from single-lens microlensing, and for ~1/3 of those the anomaly is likely caused by a planetary companion. For each of the 224 events we have performed numerical ray-tracing simulations to calculate the detection efficiency of possible companions as a function of companion-to-host mass ratio and separation. Accounting for the detection efficiency, we find that 55 - 22 + 34 % of microlensed stars host a snowline planet. Moreover, we find that Neptunes-mass planets are ~ 10 times more common than Jupiter-mass planets. The companion-to-host mass ratio distribution shows a deficit at q ~ 10-2, separating the distribution into two companion populations, analogous to the stellar-companion and planet populations, seen in radial-velocity surveys around solar-like stars. Our survey, however, which probes mainly lower-mass stars, suggests a minimum in the distribution in the super-Jupiter mass range, and a relatively high occurrence of brown-dwarf companions.

Abstract
Cdc42, a small Rho GTPase family member, has been shown to regulate multiple cellular functions in vitro, including actin cytoskeletal reorganization, cell migration, proliferation, and gene expression. However, its tissue-specific roles in vivo remain largely unknown, especially in postnatal cartilage development, as cartilage-specific Cdc42 inactivated mice die within a few days after birth. In this study, we investigated the physiological functions of Cdc42 during cartilage development after birth using tamoxifen-induced cartilage-specific inactivated Cdc42 conditional knockout (Cdc42 (fl/fl); Col2-CreERT) mice, which were generated by crossing Cdc42 flox mice (Cdc42 (fl/fl)) with tamoxifen-induced type II collagen (Col2) Cre transgenic mice using a Cre/loxP system. The gross morphology of the Cdc42 cKO mice was shorter limbs and body, as well as reduced body weight as compared with the controls. In addition, severe defects were found in growth plate chondrocytes of the long bones, characterized by a shorter proliferating zone (PZ), wider hypertrophic zone (HZ), and loss of columnar organization of proliferating chondrocytes, resulting in delayed endochondral bone formation associated with abnormal bone growth. Our findings demonstrate the importance of Cdc42 for cartilage development during both embryonic and postnatal stages.

Abstract
Craniofacial deformities with multifactorial etiologies, such as cleft palate and facial dysmorphism, represent some of the most frequent congenital birth defects seen in humans. Their pathogeneses are often related to cranial neural crest (CNC) cells. During CNC cell migration, changes in cell shape and formation, as well as maintenance of subcellular structures, such as filopodia and lamellipodia, are dependent on the complex functions of Rho family small GTPases, which are regulators of actin cytoskeletal organization. Cdc42, a member of the Rho family of small GTPases, is known to play critical roles in organogenesis of various tissues. To investigate the physiological functions of Cdc42 during craniofacial development, we generated CNC-derived cell-specific inactivated Cdc42 mutant mice (Cdc42fl/fl;P0-cre). Most of the Cdc42fl/fl;P0-cre neonates were viable at birth, though they appeared weaker and no milk was found in their stomachs, and all died within a few days. They had a short face and intracranial bleeding, and abnormal calcification of the cranium. Cdc42fl/fl;P0-cre neonates also demonstrated a cleft palate and there was no fusion of the secondary palate because of failure of palatal shelf elongation for the process of palate closure. Cdc42 is crucial for facial and palatal formation during craniofacial development. Cranial neural crest-derived cell-specific Cdc42 deletion mutant mice were generated. Cdc42 mutant mice were found to have a cleft palate. Palatal shelf elongation failed in Cdc42 mutant mice.

Abstract
We report on the measurement of the first 2(+) and 4(+) states of (66)Cr and (70,72)Fe via in-beam γ-ray spectroscopy. The nuclei of interest were produced by (p,2p) reactions at incident energies of 260 MeV/nucleon. The experiment was performed at the Radioactive Isotope Beam Factory, RIKEN, using the DALI 2γ-ray detector array and the novel MINOS device, a thick liquid hydrogen target combined with a vertex tracker. A low-energy plateau of 2(1)(+) and 4(1)(+) energies as a function of the neutron number was observed for N≥38 and N≥40 for even-even Cr and Fe isotopes, respectively. State-of-the-art shell model calculations with a modified Lenzi-Nowacki-Poves-Sieja (LNPS) interaction in the pfg(9/2)d(5/2) valence space reproduce the observations. Interpretation within the shell model shows an extension of the island of inversion at N=40 for more neutron-rich isotopes towards N=50.

Abstract
Absolute cross sections for isotopically identified products formed in multinucleon transfer in the (136)Xe+(198)Pt system at ∼8 MeV/nucleon are reported. The isotopic distributions obtained using a large acceptance spectrometer demonstrated the production of the "hard-to-reach" neutron-rich isotopes for Z<78 around the N=126 shell closure far from stability. The main contribution to the formation of these exotic nuclei is shown to arise in collisions with a small kinetic energy dissipation. The present experimental finding corroborates for the first time recent predictions that multinucleon transfer reactions would be the optimum method to populate and characterize neutron-rich isotopes around N=126 which are crucial for understanding both astrophysically relevant processes and the evolution of "magic" numbers far from stability.
