Our current taxonomic perspective on Entamoeba is largely based on small-subunit ribosomal RNA genes (SSU rDNA) from Entamoeba species identified in vertebrate hosts with minor exceptions such as E. moshkovskii from sewage water and E. marina from marine sediment. Other Entamoeba species have also been morphologically identified and described from non-vertebrate species such as insects; however, their genetic diversity remains unknown. In order to further disclose the diversity of the genus, we investigated Entamoeba spp...

PURPOSE: One of the major applications of dual-energy computed tomography (DECT) is automated bone removal (BR). We hypothesized that the visualization of acute intracranial hemorrhage could be improved on BRCT by removing bone as it has the highest density tissue in the head. This preliminary study evaluated the efficacy of a DE BR algorithm for the head CT of trauma patients. METHODS: Sixteen patients with acute intracranial hemorrhage within 1 day after head trauma were enrolled in this study...

Blood pressure is regulated by extrinsic factors including noradrenaline, the sympathetic neurotransmitter that controls cardiovascular functions through adrenergic receptors. However, the fine-tuning system of noradrenaline signaling is relatively unknown. We here show that l-3,4-dihydroxyphenylalanine (L-DOPA), a precursor of catecholamines, sensitizes the vascular adrenergic receptor alpha1 (ADRA1) through activation of L-DOPA receptor GPR143. In WT mice, intravenous infusion of the ADRA1 agonist phenylephrine induced a transient elevation of blood pressure...

BACKGROUND: Clostridium septicum-infected aortic aneurysm is a fatal and rare disease. We present a fatal case of C. septicum-infected aortic aneurysm and a pertinent literature review with treatment suggestions for reducing mortality rates. CASE PRESENTATION: A 58-year-old Japanese man with an unremarkable medical history presented with a 3-day history of mild weakness in both legs, and experienced paraplegia and paresthesia a day before admission. Upon recognition of signs of an abdominal aortic aneurysm and paraplegia, we suspected an occluded Adamkiewicz artery and performed a contrast-enhanced computed tomography scan, which revealed an aortic aneurysm with periaortic gas extending from his chest to his abdomen and both kidneys...

Resistance to thyroid hormone (RTH) is a rare autosomal hereditary disorder characterized by increased serum thyroid hormone (TH) levels with unsuppressed or increased thyrotropin concentration. It remains unknown whether the coexistence of RTH with papillary thyroid carcinoma (PTC) and Hashimoto thyroiditis (HT) is incidental or whether it possesses a genetic or pathophysiological association. In the present study, a case of RTH with PTC and HT in an 11-year-old Chinese patient was examined and the clinical presentation of RTH with PTC was discussed...

Fibromyalgia is a refractory disease characterized by chronic intractable pain and psychological suffering, the cause of which has not yet been elucidated due to its complex pathology. Activation of immune cells in the brain called microglia has attracted attention as a potential underlying pathological mechanism in chronic pain. Until recently, however, technological and ethical considerations have limited the ability to conduct research using human microglia. To overcome this limitation, we have recently developed a technique to create human-induced microglia-like (iMG) cells from human peripheral blood monocytes...

Multiple sclerosis (MS) is a chronic demyelinating disease of the central nervous system characterized by recurrent and progressive demyelination/remyelination cycles, neuroinflammation, oligodendrocyte loss, and axonal pathology. Baicalein isolated from the roots of Scutellaria baicalensis has been shown to exert anti-inflammatory and anti-oxidant effects. The cuprizone model is an established mouse model of MS and causes demyelination and motor dysfunction to induce neuroinflammation such as glial activation and pro-inflammatory cytokine production...

Dipeptidyl peptidase-4 (DPP-4) inhibitors are relatively new class of anti-diabetic drugs. Some protective effects of DPP-4 on cardiovascular disease have been described independently from glucose-lowering effect. However, the detailed mechanisms by which DPP-4 inhibitors exert on endothelial cells remain elusive. The purpose of this research was to determine the effects of DPP-4 inhibitor on endothelial barrier function. Human umbilical vein endothelial cells (HUVECs) were cultured and exposed to hypoxia in the presence or absence of Diprotin A, a DPP-4 inhibitor...

Chronic pulmonary aspergillosis (CPA) is associated with mortality in patients with Mycobacterium avium complex lung disease (MAC-LD). An Aspergillus-positive respiratory specimen often reflects colonization, and thus the clinical significance of Aspergillus isolation in MAC-LD patients is not well understood. The objective of this study was to investigate the clinical characteristics and outcomes of MAC-LD patients in whom Aspergillus was isolated from respiratory specimens. We performed a retrospective review of the medical records of 329 MAC-LD patients...

The tripartite EfeUOB system functions as a low pH iron importer in Gram-negative bacteria. In the alginate-assimilating bacterium Sphingomonas sp. strain A1, an additional EfeO-like protein (Algp7) is encoded downstream of the efeUOB operon. Here we show the metal binding mode of Algp7, which carries a M_75 metallopeptidase motif. The Algp7 protein was purified from recombinant E. coli cells and was subsequently characterized using differential scanning fluorimetry, fluorescence spectrometry, atomic absorption spectroscopy, and X-ray crystallography...

Muscle dysfunction is the most important modifiable mediating factor in primary osteoarthritis because properly contracting muscles are a key absorber of forces acting on a joint. However, the pathological features of disuse muscle atrophy in osteoarthritis patients have been little studied. Vastus medialis muscles of fourteen female patients with osteoarthritis in the age range 69 to 86 years, largely immobile for one or more years, were obtained during arthroplastic surgery and analyzed histologically. These were compared to female patients without arthritis, two with patellar fracture, and two with patellar subluxation...

BACKGROUND: Patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) have a poor prognosis, even in the rituximab era. Several studies have reported the clinical importance of the peripheral blood lymphocyte-to-monocyte ratio (LMR) in various malignancies, including lymphoma. However, the prognostic value of the LMR in relapsed/refractory DLBCL has not been well evaluated. The purpose of the present study was to investigate whether the LMR at relapse can predict clinical outcomes for relapsed/refractory DLBCL patients treated with rituximab...

Endosymbiotic relationships between eukaryotic and prokaryotic cells are common in nature. Endosymbioses between two eukaryotes are also known; cyanobacterium-derived plastids have spread horizontally when one eukaryote assimilated another. A unique instance of a non-photosynthetic, eukaryotic endosymbiont involves members of the genus Paramoeba, amoebozoans that infect marine animals such as farmed fish and sea urchins. Paramoeba species harbor endosymbionts belonging to the Kinetoplastea, a diverse group of flagellate protists including some that cause devastating diseases...

OBJECTIVE: Hashimoto's thyroiditis (HT) is characterised by elevated specific auto-antibodies, including TgAb and TPOAb. Increasing evidence has demonstrated the essential role of Th17 cells in HT. However, the underlying mechanism is still unclear. Semaphorin 5A (Sema5A) is involved in several autoimmune diseases through regulation of immune cells. The aim of this study was to explore the role of Sema5A in HT. METHODS: We measured serum Sema5A levels in HT (n = 92) and healthy controls (n = 111) by ELISA...

OBJECTIVE: Previous studies did not focus on the differences in the extent of cervical lymph node (LN) dissection according to coexistent Hashimoto's thyroiditis (HT) in patients with papillary thyroid carcinoma (PTC) and its clinical impact. We aimed to determine whether extensive cervical LN dissection is responsible for favorable clinical outcomes in PTC patients with HT and whether coexistence of HT itself has an independent protective effect regardless of LN status. DESIGN: Retrospective cohort study PATIENTS: 1,369 patients with PTC who underwent total thyroidectomy with central compartment neck dissection...
