Vector flow mapping (VFM) is a novel echocardiographic technology that shows blood flow vectors and vortexes, enabled the hydrokinetic evaluation of hemodynamics within the left ventricle. VFM provides several unique parameters: circulation, vorticity, vortex area, and energy loss. The present study aims to reveal a relationship between VFM parameters and cardiac function. Five healthy Beagle dogs were anesthetized and administered with dobutamine (0, 2, 4, 8, 12 µg/kg/min). Pressure-volume diagrams were acquired to assess cardiac function using pressure-volume conductance catheter...

Layered magnesium hydroxides modified organically with tris(hydroxymethyl)aminomethane (Tris-NH2) were directly synthesized from magnesium chloride dissolved in a polar organic solvent, like dimethyl sulfoxide (DMSO), containing a small amount of water. Tris-NH2 acted as a base for precipitating magnesium hydroxides as well as an organic modifier. In contrast to the case of an aqueous solution, the use of organic solvents substantially increased the degree of modification of layered magnesium hydroxides with Tris-NH2 owing to the formation of bidentate Mg-O-C linkages by Tris-NH2 in addition to its tridentate bonding mode...

OBJECTIVES: Ischemia-reperfusion injury resulting in post-transplant lung dysfunction involves a complicated network of cytokines that has yet to be fully investigated. We analyzed temporal changes in cytokine levels in epithelial lining fluid (ELF) from the distal airways of a canine lung transplantation model. METHODS: Ischemic time was set to 18 hours to enhance lung injury in a left single-lung transplantation model. ELF was collected via bronchoscopic microsampling, a minimally-invasive technique allowing repeated sampling, hourly up to 5 hours after reperfusion started...

BACKGROUND: Treatments for unruptured anterior communicating artery (AcomA) aneurysm have relatively high morbidity. OBJECTIVE: To assess the lateral supraorbital keyhole approach for safe and complete clipping of unruptured AcomA aneurysm and evaluate the long-term clinical and radiological outcomes, including cognitive and depressive status. METHODS: A total of 63 patients (aged 41-79 yr, mean 64 yr) with relatively small AcomA aneurysms clipped via the lateral supraorbital approach were retrospectively analyzed among the 105 AcomA aneurysms treated by clipping from 2005 to 2014...

BACKGROUND: Verapamil-sensitive idiopathic left ventricular tachycardia (verapamil-ILVT) is thought to be due to a reentry within the LV fascicular system. Radiofrequency catheter ablation (RFCA) is effective for elimination of the VT; however, a long-term prognosis of patients with verapamil-ILVT is still unclear. METHODS AND RESULTS: Eighty consecutive verapamil-ILVT patients (62 men, 31±12 years-of-age, LVEF: 65±4%) were enrolled. Seventy-six (95%) cases of VT involved right bundle brunch block and left axis deviation...

BACKGROUND: A high body mass index (BMI) has been proposed as an important risk factor for pancreatic cancer. However, this association of BMI with pancreatic cancer risk has not been confirmed in Asian populations. METHODS: We evaluated the association between BMI (either at baseline or during early adulthood) and pancreatic cancer risk by conducting a pooled analysis of nine population-based prospective cohort studies in Japan with more than 340,000 subjects. Summary hazard ratios (HRs) were estimated by pooling study-specific HRs for unified BMI categories with a random-effects model...

Undifferentiated odontogenic epithelium and dental papilla cells differentiate into ameloblasts and odontoblasts, respectively, both of which are essential for tooth development. These differentiation processes involve dramatic functional and morphological changes of the cells. For these changes to occur, activation of mitochondrial functions, including ATP production, is extremely important. In addition, these changes are closely related to mitochondrial fission and fusion, known as mitochondrial dynamics...

Systemic Epstein-Barr virus (EBV)-positive T-cell lymphoproliferative disorders (T-LPD) of childhood is an extremely rare disease characterized by an aggressive clinical course and very poor prognosis. We report an adolescent male with systemic EBV-positive T-LPD of childhood after primary EBV infection, resulting in a fatal clinical course within 9 days, along with autopsy findings. A 19-year-old male without an immunocompromised status presented with an acute onset of high fever, and was hospitalized for persistent fever, vomiting and diarrhea on the 5th day from onset...

AIM: We examined the first- and second-line pharmacological treatment for delirium to determine which drugs were chosen, how and when second-line drugs were started, and the effectiveness and tolerability of those treatments. METHODS: A retrospective medical chart review was performed for delirium inpatients referred to the Department of Psychiatry, Hiroshima Citizens Hospital, from October 2011 to September 2012. Clinical diagnoses were based on ICD-10. We compared the baseline severity of delirium, duration needed for improvement, and rescue with antipsychotics between subjects given only first-line drugs and those switched to second-line drugs...

Prolyl-hydroxyproline (Pro-Hyp) is one of the major constituents of collagen-derived dipeptides. We previously reported that Pro-Hyp promotes the differentiation of osteoblasts by increasing Runx2, osterix and Col1α1 mRNA expression levels. Here, to elucidate the mechanism of Pro-Hyp promotion of osteoblast differentiation, we focus on the involvement of Foxo1 in osteoblast differentiation via Runx2 regulation and the role of Foxg1 in Foxo1 regulation. The addition of Pro-Hyp had no effect on MC3T3-E1 cell proliferation in Foxo1- or Foxg1-knockdown cells...

Atypical femoral fractures (AFFs) are defined as atraumatic or low-trauma fractures located in the subtrochanteric or diaphyseal sites. Long-term bisphosphonates (BPs) are administered to prevent fragility fractures in patients with primary osteoporosis or collagen diseases who are already taking glucocorticoids (GCs). Long-term BP use is one of the most important risk factors for AFFs. Its pathogenesis is characterized by severely suppressed bone turnover (SSBT), but whether the characteristics of patients are different regarding to location of fracture site remains unknown...

Cross-talk between inflammation and coagulation plays important roles in acute or subacute progressive pulmonary fibrosis characterized by diffuse alveolar damage. Thrombomodulin is a physiological inhibitor of high-mobility group box 1 (HMGB1) and thrombin, and may be effective for this condition. This study investigated the roles of HMGB1 and thrombin in the pathophysiology of bleomycin-induced pulmonary fibrosis and the efficacy of recombinant human soluble thrombomodulin (rhTM). Pulmonary fibrosis was induced in wild-type C57BL/6 mice by intratracheal instillation of bleomycin...

The thylakoid membrane is the site of photochemical and electron transport reactions of oxygenic photosynthesis. The lipid composition of the thylakoid membrane, with two galactolipids, one sulfolipid, and one phospholipid, is highly conserved among oxygenic photosynthetic organisms. Besides providing a lipid bilayer matrix, thylakoid lipids are integrated in photosynthetic complexes particularly in photosystems I and II and play important roles in electron transport processes. Thylakoid lipids are differentially allocated to photosynthetic complexes and the lipid bilayer fraction, but distribution of each lipid in the thylakoid membrane is unclear...

OBJECTIVE: The "dysconnection hypothesis" has been proposed as a core neural basis for schizophrenia. Although growing neuroimaging-based evidence suggests atypical functional connectivity in patients with schizophrenia, the results are inconsistent and the effects of antipsychotic treatment remain elusive. METHODS: We performed resting-state electroencephalography (EEG) in 21 drug-naïve patients with schizophrenia (14 patients were re-evaluated after administration of antipsychotic treatment) and 31 age-matched healthy control subjects...

Rhinocerebral mucormycosis (RCM) can lead to internal carotid artery thrombosis. Here, we report the first case of RCM with temporal artery thrombosis following HLA-haploidentical stem cell transplantation in an adolescent presenting with low-grade fever, right mandibular pain, and right jaw claudication. This case suggests that RCM can cause temporal artery thrombosis and should be considered as a differential diagnosis in severely immunocompromised patients with maxillary sinusitis presenting with jaw claudication...

Chondroitin sulfate (CS) is a sulfated polysaccharide produced by chondrocytes. Alkaline phosphatase (ALP) is an important enzyme involved in the mineralization of chondrocytes. In recent years, it has been reported that CS regulates the differentiation of various cells. In this study, we investigated the effect of supplemented CS on ALP activity and mineralization of the chondrogenic cell line, ATDC5. In addition, hyaluronic acid (HA), a non-sulfated and acidic polysaccharide, was used in comparison to CS...
