概要: Narcolepsy types 1 (NT1) and 2 (NT2) and idiopathic hypersomnia (IH) are thought to be a disease continuum known as narc olepsy spectrum disorders (NSDs). This study aimed to assess the prevalence of and factors associated with metabolic-syndrome-related disorders (MRDs) among patients with NSD. Japanese patients with NSD (NT1, n = 94; NT2, n = 83; and IH, n = 57) aged ≥35 years were enrolled in this cross-sectional study. MRD was defined as having at least one of the following conditions: hypertension, diabetes, or dyslipidemia. Demographic variables and MRD incidence were compared among patients in the respective NSD categories. Multivariate logistic regression analysis was used to investigate the factors associated with MRDs. Patients with NT1 had a higher body mass index (BMI) and incidence of MRD than that had by those with NT2 or IH. Age, BMI, and the presence of OSA were significantly associated with the incidence of MRD in NSDs. Age and BMI in NT1, BMI and human leukocyte antigen (HLA)-DQB1*06:02 positivity in NT2, and only age in IH were factors associated with the incidence of MRD. Obesity should be carefully monitored in narcolepsy; however, NT2 with HLA-DQB1*06:02 positive should be followed up for the development of MRD even without obesity. 続きを見る

概要: Filter-based offline analysis of atmospheric aerosol hygroscopicity coupled to composition analysis provides information complementary to that obtained from online analysis. However, its application itself and comparison to online analysis have remained limited to date. In this study, daily submicrometer aerosol particles (PM0.95, 50 % cutoff diameter 0.95 µm) were collected onto quartz fiber filters on Okinawa Island, a receptor of East Asian outflow, in the autumn of 2015. The chemical composition of water-soluble matter (WSM) in PM0.95, PM0.95 itself, and their respective hygroscopicities were characterized through the offline use of an aerosol mass spectrometer and a hygroscopicity tandem differential mobility analyzer. Thereafter, results were compared with those obtained from online analyses. Sulfate dominated the WSM mass (59 %), followed by water-soluble organic matter (WSOM, 20 %) and ammonium (13 %). WSOM accounted for most (91 %) of the mass of extracted organic matter (EOM) and the atomic O-to-C ratios (O : C) of WSOM and EOM were high (mean ± standard deviation were 0.84 ± 0.08 and 0.78 ± 0.08, respectively), both of which indicate highly aged characteristics of the observed aerosol. The hygroscopic growth curves showed clear hysteresis for most samples. At 85 % relative humidity (RH), the calculated hygroscopicity parameter κ values of the WSM (κWSM), WSOM, EOM, andPM0.95 (κPM0.95 ) were 0.50 ± 0.03, 0.22 ± 0.12, 0.20 ± 0.11, and 0.47 ± 0.03, respectively. An analysis using the thermodynamic Extended Aerosol Inorganics Model (E-AIM) shows, on average, that inorganic salts and WSOM contributed 88 % and 12 %, respectively, of the κWSM (or κPM0.95 ). High similarities were found between offline and online analysis for chemical compositions that are related to particle hygroscopicity (the mass fractions and O : C of organics and the degree of neutralization) and also for aerosol hygroscopicity. As possible factors governing the variation in κWSM, the influences of WSOM abundance and the neutralization of inorganic salts were assessed. At high RH (70 %–90 %), the hygroscopicity of WSM and PM0.95 was affected considerably by the presence of organic components; at low RH (20 %–50 %), the degree of neutralization could be important.This study not only characterized aerosol hygroscopicity at the receptor site of East Asian outflow but also shows that offline hygroscopicity analysis is an appropriate method, at least for aerosols of the studied type. The results encourage further applications to other environments and to more in-depth hygroscopicity analysis, in particular for organic fractions. 続きを見る

概要: 琉球列島の沿岸域から採集された標本に基づき, テナガオウギガニ属Chlorodiella Rathbun, 1897の7種 [ケフサテナガオウギガニC. barbata (Borradaile, 1900); ヨツハテナガオウギガニ (新称 ) C. corallicola Miyake & Takeda, 1968; ナギテナガオウギガニ (新称) C. crispipleopa Dai, Yang, Song & Chen, 1986; ヒメテナガオウギガニC. cytherea (Dana, 1852); ユビワテナガオウギガニ (新称) C. xishaensis Chen & Lan, 1978; テナガオウギガニC. laevissima (Dana, 1852); クロテナガオウギガニC. nigra (Forskål, 1775)] を報告した. これらの種のうち, ヨツハテナガオウギガニは日本沿岸から初記録である. ナギテナガオウギガニとユビワテナガオウギガニは, それぞれの種名で日本沿岸から記録されたことはないが, ヒメテナガオウギガニとして報告された記録のなかにこれら2種が含まれていることが判明した. 本研究で扱ったナギテナガオウギガニと暫定的にヒメテナガオウギガニと同定した標本は, 複数の形質によって区別できるが, どちらがC. cythereaの名義種に適合するかについて確認する必要がある. 本研究で暫定的にテナガオウギガニと同定した標本の多くは, Serène (1984) による “C. laevissima form robusta” と一致するが, この名称は不適格名である. さらに, Serène (1984) が定義した2つの型は, C. laevissimaの新参シノニムとされているMenippe martensii Krauss, 1843との比較も必要であることを指摘した. 本研究でクロテナガオウギガニと同定した標本には, 2つの変異が含まれていた. クロテナガオウギガニの正確な同定をするために, これらの変異が種内変異であるのか種の違いであるのか, またそれらとC. nigraのシノニムとの関係を再検討する必要性についても指摘した.
Seven species of the xanthid genus Chlorodiella Rathbun, 1897 [C. barbata (Borradaile, 1900); C. corallicola Miyake & Takeda, 1968; C. crispipleopa Dai, Yang, Song & Chen, 1986; C. cytherea (Dana, 1852); C. xishaensis Chen & Lan, 1978; C. laevissima (Dana, 1852) and C. nigra (Forskål, 1775)], are reported based on specimens collected from the Ryukyu Islands, southern Japan. The present study represents the first record of C. corallicola from Japanese waters. It is also found that C. crispipleopa and C. xishaensis had already been recorded from several Japanese studies as C. cytherea. The specimens, tentatively identified as C. cytherea in the present study, are distinguished from C. crispipleopa by several features, although the identity of C. cytherea s.s. described by Dana (1852) is uncertain. Most of the specimens tentatively identified as C. laevissima in the present study agree with “C. laevissima form robusta” in Serène (1984), but the name “robusta” is an unavaibale name. Furthermore, this study pointed out that it is necessary to compare Serène’s (1984) two forms with Menippe martensii Krauss, 1843, which is regarded as a junior synonym of C. laevissima. The specimens identified as C. nigra in the present study included two morphological variations. For better taxonomy of C. nigra, it is necessary to determine whether these variations are intraspecific or interspecific differences and to match these specimens with nominal species currently synonimised under C. nigra.

概要: 沖縄諸島の沿岸域から採集された標本に基づき, ケブカオビヒロガニ (新称) Typhlocarcinops hirtus Ng & Rahayu, 2020およびビロードオビヒロガニ (新称) T. cf. tonsuratusを日本初記録 として報告した. 本研究でビロードオビヒロガニと同定した標本は, 雄の第1腹肢の形状がT. tonsuratusの原記載の図と異なっていたが, ホロタイプの唯一残っている第1腹肢も破損している可能性が考えられた. 本研究ではこれら2種の形態情報を示すとともに日本産メクラガニモドキ属各種の現在の同定に対応する和名の整理も行った.
Two species of the rhizopine crabs, Typhlocarcinops hirtus Ng & Rahayu, 2020 and T. cf. tonsuratus, are reported from Japan for the first time based on specimens collected from the Okinawa Islands, central Ryukyus. The structure of male first gonopod of the specimens identified as T. cf. tonsuratus in the present study is different from the drawing of the holotype of the nominal species, but it is possible that the drawn gonopod may be damaged and thus shows an unusual condition. The morphological features of these two species are described. Moreover, Japanese names of all other Typhlocarcinops species recorded from Japan were adjusted to match current identification

概要: 琉球列島の海底洞窟 (沖縄諸島の沖縄島および伊江島, 宮古諸島の下地島) からハチノスキクザルChama cerion Matsukuma, Paulay & Hamada, 2003 の生貝を記録した. これらの標本は, 本種のホロタイプ 標本と同様に, 右殻表面に折れ曲がって重なり合う特徴的な鱗片状突起が確認され, また, この突起構造は左殻にも見られることが明らかとなった. 一方, 少なくとも本種のパラタイプ標本の一部には鱗片状突起が見らない個体が含まれており, C. cerion のパラタイプ標本にはホロタイプ標本とは異なる種 (おそらく未記載種) が含まれている可能性が示唆された. 本種の生貝記録は, トンガ王国ニウエ島で採集された一例のみとされてきたが, このパラタイプ標本はC. cerion ではない可能性があることから, 本報告が本種の確実な生貝の初記録となる. また, 本種が海底洞窟内のアンキアライン環境 (暗黒下かつ低塩分環境) に生息することも明らかとなった.
The rare chamid bivalve, Chama cerion Matsukuma, Paulay & Hamada, 2003, is recorded from submarine caves in Okinawa-jima Island and Ie-jima Island of the Okinawa Island Group, and Shimoji-jima Island of the Miyako Island Group, Ryukyu Islands, southwestern Japan. The specimens examined possessed bent over, overlapping scales that characterize the outer surface of right valve of the holotype of C. cerion, and these characteristic scales were also found in the left valve. On the other hand, these characteristic scales were not found in a paratype examined in this study. This indicates that at least one paratype is not conspecific to the holotype and they seem to consist of more than two species, including a potentially undescribed species. All the specimens of C. cerion from the Ryukyu Islands have been found in anchialine environments of submarine caves (darkness and low salinity conditions), and these records represent the first definite findings of living individuals of C. cerion.
