概要: Many blood glucose-lowering drugs cannot be used once patients with type 2 diabetes (T2D) and nonalcoholic fatty liver disease develop nonalcoholic steatohepatitis (NASH). Therefore, such patients often require insulin treatment. We aimed to determine the effect of sodium-glucose cotransporter 2 inhibitor (SGLT2i) dapagliflozin monotherapy on glucose metabolism in a mouse model of NASH/T2D, with a focus on its diuretic effects. To imitate ascites and to determine its severity by imaging, meglumine sodium amidotrizoate (MSA) was infused into the abdominal cavities of mice. The reduction in ascites induced by dapagliflozin was compared with that induced by furosemide using microcomputed tomography. The effects of each drug on hemodynamics were also compared. A dapagliflozin-related improvement in glucose tolerance was achieved in mice fed a high-fat diet (HFD) or an HFD + methionine-and-choline-deficient diet (MCDD). In dapagliflozin-treated NASH mice, hypoglycemia was not identified during 24-hour casual blood glucose monitoring. In the dapagliflozin and furosemide-treated groups, the time taken for the resolution of artificial ascites was significantly shorter than in the untreated group, and there were no significant differences between these groups. Furosemide significantly reduced the blood pressure and significantly increased the heart rate of the mice. Dapagliflozin caused a mild decrease in systolic, but not diastolic blood pressure, and the heart rate and circulating catecholamine and renin-aldosterone concentrations were unaffected. Dapagliflozin treatment improved glycemic control in the NASH mice versus untreated mice. Thus, dapagliflozin had a prompt diuretic effect but did not adversely affect the hemodynamics of mice with NASH and T2D. Therefore, it may be useful for the treatment of patients with both T2D and liver cirrhosis. 続きを見る

概要: We provide a simpler proof for an infinite product expression of Gustafson’s q-beta integral of type G_2 with 4 parameters. We extend Gustafson’s q-integral to a q-hypergeometric integral of type G_2 with 6 parameters. Under a constraint of the parameters called the balancing condition, we obtain two explicit forms of q-difference equations satisfied by the q-hypergeometric integral of type G_2. Taking limit for a parameter, the q-hypergeometric integral of type G_2 degenerates to Gustafson’s q-integral, and one of two q-difference equations becomes that satisfied by Gustafson’s q-integral. Using this we consequently have an alternative proof for the infinite product of Gustafson’s q-beta integral again. 続きを見る

概要: Batesian mimicry is a striking example of Darwinian evolution, in which a mimetic species resembles toxic or unpalatable model species, thereby receiving protection from predators. In some species exhibiting Batesian mimicry, nonmimetic individuals coexist as polymorphism in the same population despite the benefits of mimicry. In a previous study, we proposed that the abundance of mimics is limited by that of the models, leading to polymorphic Batesian mimicry in the swallowtail butterfly, Papilio polytes, on the Ryukyu Islands in Japan. We found that their mimic ratios (MRs), which varied among the Islands, were explained by the model abundance of each habitat, rather than isolation by distance or phylogenetic constraint based on the mitochondrial DNA (mtDNA) analysis. In the present study, this possibility was reexamined based on hundreds of nuclear single nucleotide polymorphisms (SNPs) of 93 P. polytes individuals from five Islands of the Ryukyus. We found that the population genetic and phylogenetic structures of P. polytes largely corresponded to the geographic arrangement of the habitat Islands, and the genetic distances among island populations show significant correlation with the geographic distances, which was not evident by the mtDNA‐based analysis. A partial Mantel test controlling for the present SNP‐based genetic distances revealed that the MRs of P. polytes were strongly correlated with the model abundance of each island, implying that negative frequency‐dependent selection interacting with model species shaped and maintained the mimetic polymorphism. Taken together, our results support the possibility that predation pressure, not isolation by distance or other neutral factors, is a major driving force of evolution of the Batesian mimicry in P. polytes from the Ryukyus. 続きを見る

概要: This study provides the first report of reflectance spectra of coral-spawn slicks and their detection using optical satellite data. The reflectance spectra show that coral-spawn slicks can be discriminated from other sea-surface features such as wave foam and floating Sargassum. Analysis of Planet Dove and Sentinel-2B imagery allowed successful detection of coral-spawn slicks at Ishigaki Island, Okinawa, Japan (24°31′40″N, 124°17′31″E), by using reflectance values in the green and red wavelength regions. This detection was attributable to both their high spatial resolution (3.7 m and 10 m, respectively) and high temporal resolution (1 day and 5 days, respectively), given that coral spawning occurs within a short period (up to several days), typically once a year, and that the coral-spawn slicks have narrow widths of ~10 m. The number of the detected coral-spawn slicks was small, possibly because of coral decline around Ishigaki Island caused by the 2016 worldwide mass coral bleaching event. High-frequency satellite observations, including those from satellite constellations, should provide a powerful tool for understanding coral-reef processes and features whose detection requires high spatial and temporal resolution. 続きを見る

V. incerta (Takeda & Miyake, 1969), V. typica Ward, 1942, V. quadrispinosa (Zehntner, 1894), and V. longipes (A. Milne-Edwards, 1873), are reported based on specimens collected from the Okinawa Island Group, Central Ryukyus, southern Japan. Notes on their morphological features and taxonomical problems are provided. The specimens identified as V. typica in the present study are distinguished from V. rotumana (Borradaile, 1900) by having tooth-shaped external orbital angle, but the distinguishable characters between the specimens examined and V. woodmasoni (Deb, 1987) remain unclear. In addition, the specimens identified as V. quadrispinosa in the present study can be distinguished from V. xishaensis (Song, 1987) by proportionally narrower male pleon and different dark pattern on the carapace, but the distinguishable characters between the specimens examined and V. nanshensis (Dai, Cai & Yang, 1994) also remain unclear. The taxonomic status and distinguishable characters of these species need to be reconsidered in future studies. Furthermore, “Litocheira quadrispinosa” recorded by Sakai (1976: pl. 191, fig. 3) from the Ryukyu Islands is found to be V. longipes instead, because of strongly converging posterolateral margin of the carapace, strongly protruding front in dorsal view, and different carapace colouration. 続きを見る

概要: Using field survey data gathered from seven villages in Youxi County in southern China and a list of famous and ancient trees and groves, this study explored the cultural roots and ecological interpretations of village fengshui forests. The results show as follows: the species of fengshui trees selected by Chinese rural villagers bear a symbolic meaning, including health, longevity, flourishing population, fortune, and wealth. Fengshui belief, clan system, village rules and regulations, fengshui worship tradition, and customs have all played important roles in villagers’ planting and conservation of fengshui forests. It is suggested that the government should recognize the cultural and ecological value of fengshui forests and integrate the local rules and village regulations into the current policy frameworks to improve fengshui (culturally preserved) forests management with favourable polices such as subsidies and conservation strategy. China’s fengshui forests suggest the cultural importance of ecosystem services from forests, and the role of culture in forest conservation. 続きを見る

概要: Treatment with tocilizumab (TCZ) to block interleukin-6 (IL-6) signalling is predicted to mitigate cytokine release syndrome (CRS) caused by coronavirus disease 2019 (COVID-19). However, the adverse effects of TCZ on patients with COVID-19 remain unclear. We herein report a patient with COVID-19 treated with TCZ who developed acute hypertriglyceridaemia. Despite favipiravir treatment, acute respiratory distress syndrome developed in a 45-year-old patient with COVID-19; thus, TCZ was initiated. The triglyceride levels greatly increased after TCZ administration. Physicians should consider the negative impact of TCZ on the lipid profile in patients with COVID-19, although COVID-19-induced CRS itself may be an aggravating factor. 続きを見る

概要: Purpose: To investigate impact of the one‐carbon metabolism (OCM) on oocyte maturity and embryo development. Methods: Th is prospective study analyzed 18 women who agreed to participate. We measured the OCM biomarkers’ concentrations including Vitamin B12 (VB12), folic acid (FA), and homocysteine (Hcy) in serum and follicular fluid (FF), and assessed their correlation. We also evaluated the influence of such OCM biomarker concentrations in mono‐FF on oocyte maturation, fertilization, embryo quality, and consequent pregnancy after embryo transfers. Results: All biomarkers showed a high concentration variability in different follicles of each woman, but their mean levels correlated with the serum levels. Among the 106 collected oocytes, 92 were mature, 59 were fertilized, and 16 yielded good‐quality embryos. We performed 26 single embryo transfers, and 7 patients achieved clinical pregnancies. VB12 concentration (FF) was significantly lower in fertilized than unfertilized oocytes by univariate analysis. In multivariate logistic analysis, a significant correlation was found between FA concentration (FF) <14.25 ng/mL and good‐quality embryos and between Hcy concentration (FF) <4.9 nmol/mL and clinical pregnancy. Conclusion: OCM in FF may affect fertilization, embryo quality, and clinical pregnancy. 続きを見る

概要: “One-pot regeneration”, which is simple regneneration method of ammonia borane (AB) using hydrazine and liquid ammonia, enables conversion of AB from hexagonal boron nitride (h-BN) after milling hydrogenation. Solution ^<11>B-NMR revealed the presence of AB after NH_3/N_2H_4 treatment of milled h-BN (BNH_x) although the yield of AB was less than 5%. The conversion mechanism was clarified as B-H bonds on the h-BN surface created by ball-milling under hydrogen pressure have an ability to form AB, which was confirmed by Thermogravimetry-Residual Gas Analysis (TG-RGA) and Infrared (IR) analysis. The reaction routes are also the same as regeneration route of polyborazylene because intermediates of AB such as (B(NH_2)_3 and hydrazine borane were found by solution ^<11>B-NMR after soaking BNH_x in liquid NH_3 and hydrazine, respectively. Because of the fact that all reactions proceed on the h-BN surface and no reaction proceeds when neat h-BN is treated, breaking of B_3N_3 ring structure and then creation of B-H bond is the key issue to increase conversion yield of AB. 続きを見る

概要: This study records six Mantodea species from several islands in the Miyako Islands, including first records from some islands. Of the six Mantodea species, four species, i.e. Statilia nemoralis (Saussure, 1870), Tenodera fasciata (Olivier, 1792), T. angustipennis Saussure, 1869 and Hierodula patellifera (Audinet-Serville, 1839), are newly recorded from some adjacent islands of Miyako-jima Island, and two species, i.e. Mantis religiosa (Linnaeus, 1758) and Amantis nawai (Shiraki, 1908), were collected from previously recorded islands in the Miyako Is. Mantis religiosa and T. fasciata were primarily observed in open grasslands, and in contrast, T. angustipennis was mainly found around forest edges on Tarama-jima I. Few nymphs and an ootheca of S. nemoralis were found in grasslands on Ikema-jima I. and Kurima-jima I. Hierodula patellifera was the most abundant among mantis species during these surveys; a number of adults and a few nymphs of this species were observed in our expedition. For Amantis nawai, specimens of only the adult stage were observed, on the dried leaf litter of the forest floor on Miyako-jima I. In addition, three Mantodea species, M. religiosa, T. angustipennis and H. patellifera, were collected from UV-LED light trap set as a counterplan against Anomala albopilosa (Hope, 1839) (Coleoptera: Scarabaeidae) on Tarama-jima I. 続きを見る

概要: A bizarre crab of the family Leucosiidae, Oreotlos pala Tan & Ng, 1996 is redescribed on the basis of four specimens , including three males and one female, collected from the Ryukyu Islands. This species was known only by the female holotype from Guam, the Mariana Islands. Our material from the Ryukyus enable us to describe the morphology of taxonomically important male characters (abdomen, telson, and gonopods) of this poorly known species for the first time. The assignment of the species to Oreotlos is fully confirmed.<br />久米島および宮古群島の伊良部島より採集された4個体の標本に基づき,コブシガニ科ツノカルイシコブシ属Oreotlos Ihle, 1918 のOreotlos pala Tan & Ng, 1996を再記載した.本種は,マリアナ諸島グアム島で採集された雌1個体に基づいて記載され,その後,川本・奥野(2003)による一般向けのガイドブックに久米島で撮影された個体の水中写真が掲載されているにすぎない稀種であった.本種の雄の形態はこれまで知られておらず,またホロタイプは鉗脚と歩脚を欠いているが,本研究の検討標本は原記載にも示されている頭胸甲背面の肝域後方,側方突出部,鰓域後方にそれぞれ1個大きく深いくぼみを有することにより,同種であると判断した.本種には標準和名が与えられていなかったため,頭胸甲背面に月面のクレーターを彷佛させる顕著なくぼみを有することから,ゲツメンカルイシコブシの新称を提唱する. 続きを見る

概要: For simultaneous screening of mixed features (MF) by DSM-5 and mixed depression (MD) by Benazzi, useful symptoms were extracted from our 12-item dimensional scale for depressive mixed state (DMX-12). Subjects were 190 consecutive cases with major depressive episode (MDE) who visited our clinic. Associations between symptomatological combinations of the DMX-12 and MF or MD were analyzed using receiver operating characteristic (ROC). The rate of MF was 4.2% while that of MD was 22.6%. Eight symptoms (overreactivity, inner tension, racing/crowded thought, impulsivity, irritability, aggression, risk-taking behavior, and dysphoria) with their AUC > 0.6 for ROC curves were specially focused on distinguishing patients with MF or MD from non-mixed patients. By using these 8 symptoms, 40.5% of the overall patients were screened as positive at the same cut-off value (≥13) for both MD and MF. The AUC of ROC curve and sensitivity/specificity were well balanced together with sufficient negative predictive values. The abovementioned 8 symptoms seem to be helpful for primary screening and negative check of DMX with considerable severity during MDE. 続きを見る

概要: 筆者らは,これまで,Single-Input Multiple-Output (SIMO) や Multiple-Input Multiple-Output (MIMO)および大規模MIMOにおける受信アンテナのハードウェアコスト削減法とし てアンテナパターン多重 (Antenna Pattern Multiplexing; APM) 技術に着目して研究を行ってきた.本稿では,APMの原理について時変指向性利得として,周波数分割多重および符号分割多重に基づく周期波形を用いて説明を試み,単一のアンテナ系統から,複数の分離可能なアンテナ出力が得られることを示す.<br />We have been studied Antenna Pattern Multiplexing (APM) technique suitable for receivers of Single-Input Multiple-Output (SIMO), Multiple-Input Multiple-Output (MIMO), and massive MIMO systems. APM technique has potential to reduce the hardware cost of the receivers, for example, size of antenna, the number of required cables, cabling cost, calibration cost, maintenance cost, etc. In this paper, we try to explain the principle of APM with time-variable directional gain designed based on Frequency Division Multiplexing (FDM) and Code Division Multiplexing (CDM). Through the paper, we show how to obtain multiple distinguishable antenna outputs from a single Radio Frequency (RF) front-end. 続きを見る
