Spin-orbit enabled unconventional Stoner magnetism.

The Stoner instability remains a cornerstone for understanding metallic ferromagnets. This instability captures the interplay of Coulomb repulsion, Pauli exclusion, and twofold fermionic spin degeneracy. In materials with spin-orbit coupling, this fermionic spin is generalized to a twofold degenerate pseudospin which is typically believed to have symmetry properties as spin.

Satisfaction Survey for Regional Clinical Pathway for Stroke Patients in Acute and Rehabilitation Hospitals in Japan.

Trans-Pacific class transmission over a standard cladding ultralow-loss 4-core fiber.

The total capacity of optical submarine cable systems as a global communication infrastructure must be continuously enlarged. Multi-core fibers (MCFs) have been studied as methods to maximize the total cable capacity under electrical power and cable space limitations. In particular, standard cladding MCFs, which are expected to have high productivity and mechanical reliability, are attractive for early deployment in submarine cable systems.

Molecular detection of porcine Enterocytozoon bieneusi infection in Peninsular Malaysia and epidemiological risk factors associated with potentially zoonotic genotypes.

Enterocytozoon bieneusi is an emerging opportunistic pathogen infecting humans, and both domestic and wild pigs are known to harbour zoonotic genotypes. There remains a paucity of information on the prevalence and epidemiology of this enteropathogen in Southeast Asia. The present study was undertaken to determine the molecular prevalence and risk factors associated with E.

Insulator-Metal Transition and Topological Superconductivity in UTe_{2} from a First-Principles Calculation.

We theoretically study superconductivity in UTe_{2}, which is a recently discovered strong candidate for an odd-parity spin-triplet superconductor. Theoretical studies for this compound faced difficulty because first-principles calculations predict an insulating electronic state, incompatible with superconducting instability. To overcome this problem, we take into account electron correlation effects by a GGA+U method and show the insulator-metal transition by Coulomb interaction.

Successful screening of sleep-disordered breathing using a pacemaker-based algorithm in Japan.

Background: Recent pacemakers with transthoracic impedance sensors have a specific algorithm identifying sleep apnea (SA). Our aim was to evaluate the algorithm in Japanese patients.

Methods: Consecutive patients implanted with a pacemaker with sleep apnea monitoring algorithm at our hospital were enrolled prospectively.

Multipole Superconductivity in Nonsymmorphic Sr_{2}IrO_{4}.

Discoveries of marked similarities to high-T_{c} cuprate superconductors point to the realization of superconductivity in the doped J_{eff}=1/2 Mott insulator Sr_{2}IrO_{4}. Contrary to the mother compound of cuprate superconductors, several stacking patterns of in-plane canted antiferromagnetic moments have been reported, which are distinguished by the ferromagnetic components as -++-, ++++, and -+-+. In this paper, we clarify unconventional features of the superconductivity coexisting with -++- and -+-+ structures.

Effect of Intraoperative Glucose Infusion on Catabolism of Adipose Tissue and Muscle Protein in Patients Anesthetized With Remifentanil in Combination With Sevoflurane During Major Surgery: A Randomized Controlled Multicenter Trial.

Background: A harmful effect of stress hormone secretion during surgery is lipolysis and proteolysis to maintain normal blood glucose levels. A well-titrated general anesthetic improves blood glucose control by suppressing secretion of these stress hormones. The aim of this study was to explore the effect of intraoperative glucose infusion on lipolysis and proteolysis in patients undergoing a general anesthetic consisting of sevoflurane and remifentanil during long (>6 hours) major surgery.

Effects of 4 Statins on Regression of Coronary Plaque in Acute Coronary Syndrome.

Background: There is no information on differences in the effects of moderate- and low-intensity statins on coronary plaque in patients with acute coronary syndrome (ACS). The aim of this study was to compare the effects of 4 different statins in patients with ACS, using intravascular ultrasound (IVUS).

Methods and results: A total of 118 patients with ACS who underwent IVUS before percutaneous coronary intervention and who were found to have mild to moderate non-culprit coronary plaques were randomly assigned to receive either 20 mg/day atorvastatin or 4 mg/day pitavastatin (moderate-intensity statin therapy), or 10 mg/day pravastatin or 30 mg/day fluvastatin (low-intensity statin therapy).

Development of Atrioventricular Block and Diagnostic Value of Stored Electrograms in Patients With Sick Sinus Syndrome and Implanted Pacemaker.

Background: The incidence of atrioventricular block (AVB) in pacemaker patients with sick sinus syndrome (SSS) is not yet known. The aim of this study was to analyze AVB episodes in SafeR mode based on stored electrograms (EGM), and determine the occurrence rate and risk factors for advanced AVB in a pacemaker population with SSS.

Methods And Results: The study included 50 consecutive patients with SSS without a history of advanced AVB who had a dual-chamber pacemaker programmed in SafeR mode.

Predictors of hypofibrinogenemia in blunt trauma patients on admission.

Purpose: Massive bleeding usually leads to critically low levels of clotting factors, including fibrinogen. Although reduced fibrinogen levels correlate with increased mortality, predictors of hypofibrinogenemia have remained poorly understood. We investigated whether findings available on admission can be used as predictors of hypofibrinogenemia.

110.9-Tbit/s SDM transmission over 6,370 km using a full C-band seven-core EDFA.

Association between gait speed as a measure of frailty and risk of cardiovascular events after myocardial infarction.

Objectives: This study sought to determine the additional clinical value of gait speed to Framingham risk score (FRS), cardiac function, and comorbid conditions in predicting cardiovascular events in patients with ST-segment elevation myocardial infarction.

Background: There is growing evidence that gait speed is inversely associated with all-cause mortality, particularly cardiovascular mortality, among the elderly.

Methods: We undertook a single-center prospective observational study of gait speed in 472 patients with ST-segment elevation myocardial infarction in Japan, between 2001 and 2008.

The influence of enclosure design on diurnal activity and stereotypic behaviour in captive Malayan Sun bears (Helarctos malayanus).

The effect of enclosure design on diurnal activity and stereotypic behaviour was assessed in 17 adult Malayan Sun bears (Helarctos malayanus), kept either in barren indoor enclosures or relatively enriched outdoor enclosures. Locomotion was the most frequent activity observed in the indoor bears, followed by resting. In contrast, conspecifics housed outdoors spent most of the time resting.

[Experience of DMAT rescue activity by doctor-helicopter in Tohoku Area after the earthquake].

We operated rescue activities in Tohoku area after the earthquake of March 11th, 2011. From our hospital, a doctor-helicopter flew to the staging care unit at Hanamaki airport with two members of the disaster medical assistance team (DMAT), one of whom was an anesthesiologist. The helicopter carried ten patients by nine flight missions, who were the victims of tsunami after the earthquake.

[Comparison of usefulness of the dorsal branch of the radial artery with the radial artery for arterial cannulation].

Methods: We reviewed medical records of patients from April 2007 to March 2010 who underwent open appendectomy for acute appendicitis and were diagnosed pathologically.

Effects of helicopter transport on red blood cell components.

Background: There are no reported studies on whether a helicopter flight affects the quality and shelf-life of red blood cells stored in mannitol-adenine-phosphate.

Materials And Methods: Seven days after donation, five aliquots of red blood cells from five donors were packed into an SS-BOX-110 container which can maintain the temperature inside the container between 2 °C and 6 °C with two frozen coolants. The temperature of an included dummy blood bag was monitored.

Intravascular ultrasound assessment of the association between spatial orientation of ruptured coronary plaques and remodeling morphology of culprit plaques in ST-elevation acute myocardial infarction.

The aim of this study was to assess the association between the spatial location of plaque rupture and remodeling pattern of culprit lesions in acute anterior myocardial infarction (MI). Positive remodeling suggests a potential surrogate marker of plaque vulnerability, whereas plaque rupture causes thrombus formation followed by coronary occlusion and MI. Intravascular ultrasound (IVUS) can determine the precise spatial orientation of coronary plaque formation.

Response of cellulase activity in pH-controlled cultures of the filamentous fungus Acremonium cellulolyticus.

Cellulase production was investigated in pH-controlled cultures of Acremonium cellulolyticus. The response to culture pH was investigated for three cellulolytic enzymes, carbomethyl cellulase (CMCase), avicelase, and beta-glucosidase. Avicelase and beta-glucosidase showed similar profiles, with maximum activity in cultures at pH 5.

A case of giant coronary artery aneurysm and literature review.

A 40-year-old man was referred to our hospital because of an abnormal shadow on the left cardiac border on the chest roentgenogram at the regular medical health examination without any symptoms. A giant coronary artery aneurysm of left anterior descending artery with a maximum diameter of approximately 50 mm was detected with computed tomography and coronary angiography. The patient was treated and followed up medically.

Optimal programming of the atrioventricular delay using the phonocardiogram.

Purpose: To predict the optimal atrioventricular (AV) delay using the phonocardiogram (PCG).

Methods: We studied 12 recipients of cardiac resynchronization therapy (CRT) system and eight recipients of dual-chamber pacemakers implanted for AV block with normal left ventricular (LV) function. The amplitude of the first heart sound (S1) was recorded by PCG and the LV outflow tract (OT) time-velocity integral (TVI) was measured by pulsed Doppler echocardiography.

Novel method of predicting the optimal atrioventricular delay in patients with complete AV block, normal left ventricular function and an implanted DDD pacemaker.

Background: The optimal atrioventricular (AV) delay setting is important for achieving optimal AV synchrony in patients with an implanted DDD pacemaker. Using pulsed Doppler echocardiography is the most common method of predicting the optimal AV delay, but it is a complicated and time-consuming method. Therefore, an automatic optimizing function of the AV delay at different atrial rates is desirable for achieving a favorable hemodynamic state.

Long-term electrocardiographic follow-up from childhood of an adult patient with Brugada syndrome associated with sick sinus syndrome.

We had the unique opportunity of following the electrocardiographic (ECG) course of a 13-year-old male with sinus dysfunction and atrial flutter who subsequently developed a Brugada-type ECG pattern associated with sick sinus syndrome at 25 years old. Family history showed that the patient's mother and maternal grandfather suddenly died while sleeping at night. When the patient was 13 years old, he lost consciousness after running a marathon.
