Specific heat and magnetization measurements have been performed on high-quality single crystals of filled skutterudite ${\mathrm{PrFe}}_{4}{\mathrm{P}}_{12}$ in order to study the high-field heavy-fermion state (HFS) low-field ordered (ODS). From a broad hump observed $C/T$ vs T HFS for magnetic fields applied along $〈100〉$ direction, Kondo temperature $\ensuremath{\sim}9\mathrm{K}$ existence ferromagnetic Pr-Pr interactions are deduced. The ${}^{141}\mathrm{Pr}$ nuclear Schottky...
We report the de Haas--van Alphen (dHvA) experiment on filled skutterudite ${\mathrm{PrFe}}_{4}{\mathrm{P}}_{12}$ exhibiting apparent Kondo-like behaviors in transport and thermal properties. have found enormously enhanced cyclotron effective mass ${m}_{\mathrm{c}}^{*}=81{m}_{0}$ high field phase, which indicates that is first Pr compound really heavy has been unambiguously confirmed. Also low nonmagnetic ordered phase (LOP), we observed dHvA branch with ${m}_{\mathrm{c}}^{*}=10{m}_{0}$...
To determine optimal settings for airway pressure (AWP), pneumoperitoneum (PPP), and central venous (CVP) in pure laparoscopic hepatectomy.High PPP is often employed to control bleeding from the hepatic vein during hepatectomy; however, there a risk of pulmonary gas embolism. We noted that decreases AWP were effective.After establishing carbon dioxide 6 male piglets maintaining at 25 mmHg, CVP was measured 3 times each 9 levels pressure, which increased increments 5 cmH2O 0 40 cmH2O. same...
<h3>Objective</h3> To investigate whether or not the lesions in sporadic amyotrophic lateral sclerosis (ALS) originate from a single focal onset site and spread contiguously by prion-like cell-to-cell propagation rostrocaudal direction along spinal cord, as has been hypothesised (the 'single seed simple propagation' hypothesis). <h3>Methods</h3> Subjects included 36 patients with ALS initial symptoms bulbar, respiratory upper limb regions. Abnormal spontaneous activities needle...
Background: Our recent report showed that 1.5-T pulsed arterial spin labeling (ASL) magnetic resonance (MR) perfusion imaging (1.5-T Pulsed ASL [PASL]), which is widely available in the field of neuroemergency, useful for detecting ictal hyperperfusion. However, visualization intravascular signals, namely, transit artifact (ATA), more remarkable than 3-T pseudocontinuous and easily confused with focal To eliminate ATA enhance detectability (peri) hyperperfusion, we developed subtraction...
Neuronal intranuclear inclusion disease (NIID) is a rare, neurodegenerative disorder characterized by the presence of eosinophilic hyaline inclusions, which are ubiquitin-positive and p62-positive, in neuronal somatic cells; this can be observed on skin biopsy. Although patients with NIID present variety symptoms that often make diagnosis difficult, characteristic high-signal intensity corticomedullary junction diffusion-weighted imaging (DWI) provides clue to NIID. We case 57-year-old woman...
We report transport measurements on high quality RERu4Sb12 single crystals under magnetic fields up to 14 T and temperatures down 0.3 K. CeRu4Sb12 exhibits anomalous features in all the properties, compared those for RE = La, Pr Nd. The thermoelectric power (TEP) shows a huge positive peak over 100 μ V K−1 near 90 Hall coefficient, ∼2.0 × 10−9m3 C−1 at room temperature, drastic increase below ∼100 K RH ≈ 5.2× 10−8m3 At low ∼3 K, TEP an apparent anomaly correlated with non-Fermi-liquid...
Mobile radiography allows for the diagnostic imaging of patients who cannot move to X-ray examination room. Therefore, mobile equipment is useful have difficulty with movement. However, staff are exposed scattered radiation from patient, and they can receive potentially harmful doses during radiography. We estimated occupational exposure using phantom measurements. Scattered distribution was investigated a survey meter. The efficacy radiation-reducing methods also evaluated. dose decreased...
Wallenberg's syndrome (WS) is caused by a stroke in the lateral medulla and can present with various symptoms. One of main symptoms vertigo, which be misdiagnosed as noncentral vertigo (NCV). Approximately 90% patients acute WS have difference body surface temperature (BST) due to autonomic pathway disturbances from infarction. Additionally, thermography aid diagnosis; however, whether BST differences occur NCV unclear.
In newt testis, spermatocytes never appear during winter, because secondary spermatogonia die by apoptosis just before meiosis. the current study, we examined effect of low temperatures on spermatogenesis. Incubation newts at (8, 12, 15 degrees C) induced defects in spermatogenesis a temperature-dependent manner. At 8 C, multinucleated giant cells (MGCs) were observed and proceeded beyond Although completed meiotic divisions 12 severe cell death was spermatids. C both normal abnormal...
In this paper data mining and machine learning applications for educational big in the university are examined. We proposed prediction models analytics using student teaching show effectiveness of methods. Some examples practical will be shown to verify effectiveness.
The diagnostic reference level (DRL) is an effective tool for optimising protection in medical exposures to patients. However regarding air kerma at the patient entrance point (Ka,r), one of DRL quantities endoscopic retrograde cholangiopancreatography (ERCP), manufacturers use a variety International Electrotechnical Commission and their own specific definitions point. research question this study was whetherKa,ris appropriate as quantity ERCP. purpose evaluate difference betweenKa,rand...
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease. A common characteristic of ALS pathology cytoplasmic inclusions primarily composed transactive response DNA-binding protein 43 kDa (TDP-43). Production TDP-43 in the central nervous system strictly regulated, but it not known whether this also true skin patients. We found gradual significant reduction epidermal mRNA expression with illness progression patients upper-limb onset. However, immunoblotting analysis revealed...
Abstract Introduction Acute Wallenberg's syndrome (WS) is sometimes misdiagnosed as a nonstroke disease including auditory vertigo, and careful neurological examination required for precise diagnosis. Lateral difference of body surface temperature (BST) had been reported symptom WS, although further details this are currently lacking. Our aim was to investigate the laterality BST patients with acute WS using thermography usefulness detect WS. Methods Nine consecutive new‐onset nine pontine...
In Japan there is no consensus on how to efficiently measure quality indicators (QIs), defined as a standard of care, for acute ischemic stroke (AIS). Using information from health insurance claims database and electronic medical records, we evaluated the feasibility validity measuring QIs AIS patients who received intravenous recombinant tissue plasminogen activator (IV rt-PA) or endovascular therapy (EVT).Methods Results:AIS receiving rt-PA EVT between 2013 2015 were identified. We...
Aiming at small high-speed rotating machines, this paper proposes a Lorentz force type self-bearing motor, where new four-pole winding configuration is used to make it function both as synchronous permanent-magnet motor and magnetic bearing. Due using dominantly, the proposed has some good points such linearity of control facility design analysis. And compared with 8-pole previously developed, advantageous high speed. Focusing on feasibility introduces prototype, which manufactured in disk...
Obtaining information on invisible vasculature distal to the occlusion site helps deploy a stent retriever safely during mechanical thrombectomy for large-vessel occlusion. It is essential reduce amount of contrast used detecting vessels because acute ischemic stroke patients tend have chronic kidney disease and with severe are at an increased risk contrast-associated injury. We assessed whether could be visualized angiographic images using flat panel detector CT acquired following...
上錐体静脈を介し後頭蓋窩へ逆流を伴う硬膜動静脈瘻は,脳幹および小脳出血の危険性がある.観血的な治療より低侵襲な血管内治療や放射線治療が優先される状況も多い.これらの治療で根治が得られない場合でも,上錐体静脈が唯一の流出路の場合は観血的な遮断が依然有用である.
