Middle mediastinal paragangliomas are very rare, slow-growing tumors, but almost all of them are very hypervascular tumors. Complete surgical resection is difficult to achieve because of their proximity to the heart, great vessels, and trachea. We report successful complete resection incorporating preoperative embolization and a clamshell bilateral thoracotomy. Dr Matsumoto

An 84-year-old man was admitted to our hospital with a 1-month history of epigastralgia. Upper gastrointestinal endoscopy revealed gastric cancer and a gastric submucosal tumor (SMT) on the greater curvature of the gastric body. By endoscopic ultrasonography, SMT was demonstrated as a well-circumscribed, smooth-bordered and hypoechoic mass localized in the submucosal layer. Total gastrectomy was performed. The histology of the resected specimen revealed a gastric lipoma and an early gastric cancer ...

A simple and compact instrument for NO2 measurement by laser-induced fluorescence (LIF) technique with a pulsed solid state laser and a multi-pass excitation system was developed and optimized for several conditions. As a result of laboratory experiment, the limit of detection (LOD) reached 94 pptv for 60 s integration. It was thought that an LIF instrument with this LOD value would be capable of quantifying sub-ppbv NO2 in unpolluted marine atmosphere. As the second step, a field test of the instrument ...

A lysophospholipid series, such as lysophosphatidic acid, lysophosphatidylserine, and lysophosphatidylcholine (LPC), is a bioactive lipid mediator with diverse physiological and pathological functions. LPC has been reported to induce insulin secretion from pancreatic beta-cells, however, the precise mechanism has remained elusive to date. Here we show that an orphan G-protein-coupled receptor GPR119 plays a pivotal role in this event. LPC potently enhances insulin secretion in response to high concentrations ...

We previously designed and synthesized an NF-κB inhibitor, dehydroxymethylepoxyquinomicin (DHMEQ), that showed anti-inflammatory activity in vivo . In the present study we looked into its mechanism of inhibition. DHMEQ inhibited tumor necrosis factor-α (TNF-α)- and 12- O -tetradecanoylphorbol-13-acetate-induced transcriptional activity of NF-κB in human T cell leukemia Jurkat cells. It also inhibited the TNF-α-induced DNA binding of nuclear NF-κB but not the phosphorylation and degradation of IκB. Moreover, ...

ABSTRACT Background and objective: More than 100 000 Japanese die of pneumonia every year. The number of people residing in nursing homes is increasing with the ageing of the population. In 2005, the American Thoracic Society/Infectious Diseases Society of America (ATS/IDSA) published important guidelines for the management of healthcare‐associated pneumonia (HCAP). In Japan, however, the optimum strategy for management of HCAP is still unclear. The purpose of this study was to clarify the clinical ...

Malectin was first discovered as a novel endoplasmic reticulum (ER)-resident lectin from Xenopus laevis that exhibits structural similarity to bacterial glycosylhydrolases. Like other intracellular lectins involved in glycoprotein quality control, malectin is highly conserved in animals. Here results from in vitro membrane-based binding assays and frontal affinity chromatography confirm that human malectin binds specifically to Glc(2)Man(9)GlcNAc(2) (G2M9) N-glycan, with a K(a) of 1.97 × 10(5) M(-1), ...

The intestinal resident Candida glabrata opportunistically infects humans. However few genetic factors for adaptation in the intestine are identified in this fungus. Here we describe the C. glabrata CYB2 gene encoding lactate dehydrogenase as an adaptation factor for survival in the intestine. CYB2 was identified as a virulence factor by a silkworm infection study. To determine the function of CYB2, we analysed in vitro phenotypes of the mutant Δcyb2. The Δcyb2 mutant grew well in glucose medium ...

ER-associated degradation (ERAD) is an ER quality-control process that eliminates terminally misfolded proteins. ERdj5 was recently discovered to be a key ER-resident PDI family member protein that accelerates ERAD by reducing incorrect disulfide bonds in misfolded glycoproteins recognized by EDEM1. We here solved the crystal structure of full-length ERdj5, thereby revealing that ERdj5 contains the N-terminal J domain and six tandem thioredoxin domains that can be divided into the N- and C-terminal ...

Acute lung injury is a critical illness syndrome consisting of acute respiratory failure with bilateral pulmonary infiltrates that is refractory to current therapies. Acute lung injury is characterized by injury of the alveolar capillary barrier, neutrophil accumulation, and induction of pro-inflammatory cytokines followed by devastating lung fibrosis.

Osmotic stress activates MAPKs, including JNK and p38, which play important roles in cellular stress responses. Transforming growth factor-beta-activated kinase 1 (TAK1) is a member of the MAPK kinase kinase (MAPKKK) family and can activate JNK and p38. TAK1 can also activate IkappaB kinase (IKK) that leads to degradation of IkappaB and subsequent NF-kappaB activation. We found that TAK1 is essential for osmotic stress-induced activation of JNK but is not an exclusive mediator of p38 activation. Furthermore, ...

Prokineticins, multifunctional secreted proteins, activate two endogenous G protein-coupled receptors PKR1 and PKR2. From in situ analysis of the mouse brain, we discovered that PKR2 is predominantly expressed in the olfactory bulb (OB). To examine the role of PKR2 in the OB, we created PKR1- and PKR2-gene-disrupted mice ( Pkr1 −/− and Pkr2 −/− , respectively). Phenotypic analysis indicated that not Pkr1 −/− but Pkr2 −/− mice exhibited hypoplasia of the OB. This abnormality was observed in the early developmental stages ...

Adult T-cell leukemia (ATL) is an intractable malignancy of CD4+ T cells that is etiologically associated with infection by human T-cell leukemia virus-type I. Most individuals in the chronic stage of ATL eventually undergo progression to a highly aggressive acute stage. To clarify the mechanism responsible for this stage progression, we isolated CD4+ cells from individuals in the chronic (n=19) or acute (n=22) stages of ATL and subjected them to profiling of gene expression with DNA microarrays containing > ...

Vitamin K2 (VK2) is an anti-proliferative agent toward a variety of cancer including hepatocellular carcinoma (HCC). Because the growth inhibitory effect of VK2 to HCC has not been established yet, we investigated it in HCC cells in vitro. VK2 inhibited growth of Hep3B, but not of HepG2, HLF, and Huh6. VK2 induced the cell cycle arrest at the G1 phase and involvement of apoptosis was suggested because the sub-G1 fraction appeared in flow cytometric analysis and nuclear condensation and fragmentation ...

We investigated adiabatic changes in a near-critical fluid on acoustic time scales using an ultrasensitive interferometer. A sound emitted by very weak continuous heating caused a stepwise adiabatic change at its front with a density change of order ${10}^{\ensuremath{-}7}\phantom{\rule{0.3em}{0ex}}\mathrm{g}∕{\mathrm{cm}}^{3}$ and a temperature change of order ${10}^{\ensuremath{-}5}\phantom{\rule{0.3em}{0ex}}\mathrm{K}$.

Epstein-Barr virus latent membrane protein 1 (LMP1) activates NF-κB and c-Jun N-terminal kinase (JNK), which is essential for LMP1 oncogenic activity. Genetic analysis has revealed that tumor necrosis factor receptor-associated factor 6 (TRAF6) is an indispensable intermediate of LMP1 signaling leading to activation of both NF-κB and JNK. However, the mechanism by which LMP1 engages TRAF6 for activation of NF-κB and JNK is not well understood. Here we demonstrate that TAK1 mitogen-activated protein ...
