Labeling experiments have established that cholesterol is converted into alpha-and beta-ecdysones in isolated abdomens of silkworm larvae. Since the do not contain prothoracic glands, a doubt cast on long-standing principle insect endocrinology glands are source ecdysone secretion.
Interleukin (IL)-33, which is a member of the IL-1 family cytokines, now recognized as an important contributor to Th2-type immune responses. We examined whether levels IL-33 in sera and nasal secretions are upregulated allergic rhinitis (AR) patients, we tested for correlations between level parameters atopy symptom score.The study included 24 Japanese cedar pollinosis patients (12 male 12 female with mean age 47.7 years) history moderate-to-severe AR, 14 house-dust-mite-sensitized AR (9 5...

(1) By partial substitution (GaCl(4))(-) by (MCl(4))(2-) [M = Co, Zn] in the anion blocking layer lambda-ET(2)(GaCl(4))(-) [ET bis(ethylenedithio)tetrathiafulvalene], single crystals lambda-ET(2)(GaCl(4))(-)(1-x)(MCl(4))(2-)(x) [x 0.0, 0.05, 0.06] have been obtained. resistivity at room temperature decreases from 3 Omega cm (x 0.0) to 0.1 0.06) doping antiferromagnet an...
Abstract C 60 /polyaniline (PANI) nanocomposites have been synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate in presence using an interfacial reaction. When compared pure PANI nanofibers from similar process, diameter obtained /PANI was increased because encapsulation into during polymerization, which resulted charge‐transfer interactions between and fragment PANI. In addition, resulting low initial /aniline molar ratio (less than 1:25) showed homogenous...

Photochemical reactions between photo-excited C60 and borates (–BPh4 –BPh3Bu) have been investigated by steady-state photolysis laser flash photolysis. On of in the presence polar solvents, absorption C60–˙ increases with irradiation time, suggesting that irreversible photoinduced electron-transfer occurs. By measurements transient spectra, it is indicated electron transfer takes place from borate anions to 3C60*, yielding ˙BPh3R (R = Ph or Bu), which latter dissociates into Ph3B R˙,...
現在日本で保険適応のある嗅覚検査には, 基準嗅力検査と静脈性嗅覚検査の二種あるが, 基準嗅力検査は実施率, 普及率ともに低く, 静脈性嗅覚検査は疼痛を伴う検査であり患者への侵襲が高い. 嗅覚同定能検査の一つとして開発されたOpen Essence (以下, OE) は, 現在医療保険の適応はないが, その臨床的有用性が期待されている. 今回われわれは嗅覚障害患者に対するOEと自覚症状, 基準嗅力検査, および静脈性嗅覚検査との比較検討を行った. 当院嗅覚外来患者のうち, 嗅覚の評価が可能であった122例を対象とした. OEスコアと基準嗅力検査, 静脈性嗅覚検査, また嗅覚障害に対する自覚症状としてのVisual Analog Scale (VAS) と日常のにおいアンケートとの間にはそれぞれ有意な相関を認めた. また静脈性嗅覚検査において嗅覚脱失を認めた群はOEの正答率が有意に低かった. OEは従来からの検査法である基準嗅力検査と静脈性嗅覚検査および自覚症状をよく反映するため, 一般臨床において広く利用可能な嗅力検査であると考える. なお,...
Abstract Objectives : It can be surmised that the cell cycle must involved in proliferation of epithelium middle ear cholesteatoma. Thus a comparative study was conducted levels expression cyclin‐dependent kinase 2 (cdk2) and 4 (cdk4)—substances known to cycle—in cholesteatoma normal bony region external canal. In addition, it has been reported cytokines is accelerated response subepithelial inflammation. This suggests an interaction between subepithelium, which subject paracrine regulation,...
自給肥料中心であった江戸時代から明治初期にかけての農村における土地利用を明らかにするため, 当時の土地利用を記した迅速測図の原図をGISで読み取り解析した。研究対象として, 北関東の代表的な谷津田地形を有する茨城県牛久・岡見地区を選択した。解析の結果, 当時の牛久・岡見地区では, 谷津田間に自給肥料供給地として共同利用されていたと思われる林地や草地が多く見られた。農村周辺には畑地と林地, 村から離れた台地上の中心地域には草地が配置される「村落-畑地-林地-草地-林地-畑地-村落」といった連鎖的土地利用が存在していたことが判明した。
Abstract Electrical resistivities and IR spectra of new mixed cation (Cu/Li)-DCNQI systems were examined. (MeBr-DCNQI)2Cu1−xLix (0.25 &lt; x 0.5) remains in the metallic state down to 4 K. The stretching frequency C=N(imine) DCNQI shows a linear dependence on charge DCNQIf which is consistent with valency Cu (Cu+1.3).
Five θ-type BETS salts [BETS = bis(ethylenedithio)tetraselenafulvalene], θ-BETS2RbCo(SCN)4, θ-BETS2RbZn(SCN)4, θ-BETS2CsCo(SCN)4, θ-BETS2CsZn(SCN)4, and θ-BETS2Ag(CN)2, have been newly prepared by the electrocrystallization method. The crystal structure analyses indicate that former four are isostructural to BEDT-TTF analogues. [BEDT-TTF bis(ethylenedithio)tetrathiafulvalene] However, metal−insulator transition temperatures of much lower than those salts, due smaller U/W (U, intramolecular...
In the present study, we investigated effect of kamishoyosan (KSS) on conditioned fear-induced freezing in ovariectomized (OVX) rats. Socially isolated OVX rats showed longest time among following four groups: group-housed sham-operated (Sham), Sham, OVX, and Repeated oral administration KSS (30-300 mg/kg) reduced socially The reduction by was reversed flumazenil (3 bicuculline mg/kg). These findings suggest that GABAA-benzodiazepine receptor complex is involved anxiolytic
More than 30% of patients with epilepsy are refractory and have inadequate seizure control. Focal cortical cooling (FCC) suppresses epileptiform discharges (EDs) in focal epilepsy. However, little is known about the mechanism by which FCC inhibits seizures at 15°C, treatment highly invasive. Therefore, new antiepileptic drugs needed that produce same effects as but different mechanisms action. To address this need, we focused on transient receptor potential melastatin 8 (TRPM8), an ion...

Aim Symptoms of dementia are classified into cognitive dysfunction and behavioral psychological symptoms dementia, including sleep disturbance. Yokukansan (YKS) is effective for disturbance in patients with but the mechanisms still unclear. In this study, we evaluated rats cerebral ischemia. We investigated effect YKS on ischemia-treated rats. Methods Cerebral ischemia was induced by twice occluding both common carotid arteries. Wakefulness, non-rapid eye movement (NREM) sleep, rapid (REM)...
Epilepsy is a relatively common condition, but more than 30% of patients have refractory epilepsy that inadequately controlled by or resistant to multiple drug treatments. Thus, new antiepileptic drugs based on newly identified mechanisms are required. A previous report revealed the suppressive effects transient receptor potential melastatin 8 (TRPM8) activation penicillin G-induced epileptiform discharges (EDs). However, it unclear whether TRPM8 agonists suppress epileptic seizures affect...

Background: Febrile seizures (FSs) are the most frequent type of in infancy and childhood. Epileptiform discharges (EDs) on electroencephalogram at time first FS recurrence can increase risk epilepsy development. Therefore, inhibition EDs is important. Recently, WS-3, a transient receptor potential melastatin 8 (TRPM8) agonist, reportedly suppressed penicillin G-induced cortical-focal EDs. However, effects TRPM8 agonists FSs remain unknown. In this study, we aimed to clarify absence...
