Spontaneous spinal epidural hematoma with hemiparesis: A stroke mimic.

Spontaneous spinal epidural hematoma (SSEH) is a rare cause of neck pain and hemiparesis. Clinicians should keep SSEH in mind as a rare stroke mimic presenting with hemiparesis to avoid needless and potentially hazardous thrombolytic therapy. Taking a careful history is useful for making a correct diagnosis.

Cellular senescence with SASP in periodontal ligament cells triggers inflammation in aging periodontal tissue.

The direct cause of periodontitis is periodontopathic bacteria, while various environmental factors affect the severity of periodontitis. Previous epidemiological studies have shown positive correlations between aging and periodontitis. However, whether and how aging is linked to periodontal health and disease in biological processes is poorly understood.

Autophagy facilitates type I collagen synthesis in periodontal ligament cells.

Autophagy is a lysosomal protein degradation system in which the cell self-digests its intracellular protein components and organelles. Defects in autophagy contribute to the pathogenesis of age-related chronic diseases, such as myocardial infarction and rheumatoid arthritis, through defects in the extracellular matrix (ECM). However, little is known about autophagy in periodontal diseases characterised by the breakdown of periodontal tissue.

Splenic mass of uncertain etiology in a 15-year-old male patient: a case report.

Background: There are few reports on spleen masses, and solitary splenic abscesses with abdominal pain have not been reported in younger age groups. We report a case of a splenic mass of uncertain etiology in a 15-year-old boy.

Case Presentation: A 15-year-old boy visited the emergency department with abdominal pain.

Effect of β-Cyclodextrin on Physicochemical Properties of an Ionic Liquid Electrolyte Composed of -Methyl--Propylpyrrolidinium bis(trifluoromethylsulfonyl)amide.

Ionic liquids (ILs) are promising electrolyte materials for developing next-generation rechargeable batteries. In order to improve their properties, several kinds of additives have been investigated. In this study, β-cyclodextrin (β-CD) was chosen as a new additive in IL electrolytes because it can form an inclusion complex with bis(trifluoromethylsulfonyl)amide (TFSA) anions.

Effects of ethyl acetate extract of Kaempferia parviflora on brown adipose tissue.

We have previously reported the effects of Kaempferia parviflora (KP), including anti-obesity, preventing various metabolic diseases, and regulating differentiation of white adipose cells. In this study we used Tsumura, Suzuki, Obese Diabetes (TSOD) mice--an animal model of spontaneous obese type II diabetes--and primary brown preadipocytes to examine the effects of the ethyl acetate extract of KP (KPE) on brown adipose tissue, which is one of the energy expenditure organs. TSOD mice were fed with MF mixed with either KPE 0.

A novel enzyme-based antimicrobial system comprising iodide and a multicopper oxidase isolated from Alphaproteobacterium strain Q-1.

Alphaproteobacterium strain Q-1 produces an extracellular multicopper oxidase (IOX), which catalyzes iodide (I-) oxidation to form molecular iodine (I2). In this study, the antimicrobial activity of the IOX/iodide system was determined. Both Gram-positive and Gram-negative bacteria tested were killed completely within 5 min by 50 mU mL(-1) of IOX and 10 mM iodide.

Endoscopic diagnosis of early neoplasia of the esophagus with narrow band imaging: correlations among background coloration and iodine staining findings.

Background And Aim: It was previously reported that high-grade intraepithelial neoplasia of the esophagus turns pink within a few minutes after iodine staining (pink-color sign; PCS); however, iodine staining is uncomfortable. By using narrow band imaging (NBI), color change in the area between the intraepithelial papillary capillary loop (background coloration; BGC) is often observed within the brownish area. The diagnostic usefulness of BGC findings for differentiating high-grade intraepithelial neoplasia from low-grade intraepithelial neoplasia was evaluated.

Identification of a high risk gastric cancer group using serum pepsinogen after successful eradication of Helicobacter pylori.

Background And Aim: Pepsinogen (PG) method is widely used to identify high risk groups of gastric cancer. It is very useful before Helicobacter pylori eradication, but after eradication the method becomes useless because the PGI, PGII, PGI/II ratios change. Therefore, we aimed to identify a high risk group for gastric cancer using serum pepsinogen after successful eradication of H.

Frequency of Helicobacter pylori -negative gastric cancer and gastric mucosal atrophy in a Japanese endoscopic submucosal dissection series including histological, endoscopic and serological atrophy.

Background: The definition of Helicobacter pylori-negative gastric cancer depends on the accuracy of diagnosis of H. pylori infection. The aim of this study was to determine the frequency of H.

Iodide oxidation by a novel multicopper oxidase from the alphaproteobacterium strain Q-1.

Alphaproteobacterium strain Q-1 is able to oxidize iodide (I(-)) to molecular iodine (I(2)) by an oxidase-like enzyme. One of the two isoforms of the iodide-oxidizing enzyme (IOE-II) produced by this strain was excised from a native polyacrylamide gel, eluted, and purified. IOE-II appeared as a single band (51 kDa) and showed significant in-gel iodide-oxidizing activity in sodium dodecyl sulfate-polyacrylamide gel electrophoresis without heat treatment.

Myelodysplastic syndrome of del 20q with plasma cell dysplasia.

Deletion of the long arm of chromosome 20 (del 20q) has been observed in patients with myelodysplastic syndrome (MDS) or myeloid malignancies. We experienced an MDS female case of del 20q accompanied by clusters of plasmacytic cells in bone marrow. Her bone marrow cells showed morphological abnormalities in three lineages and the chromosomal abnormality of 46, XX, del (20) (q11.

[Repetition of Helicobacter cinaedi infections during chemotherapy for malignant lymphoma].

A 70-year-old male, who had undergone resection of gastric malignant lymphoma in 1992, presented with cervical lymph node swelling in January 2008. Pathological examination of the lymph node biopsy demonstrated recurrence of malignant lymphoma, and he was treated with the R-CHOP regimen. Although he did not develop fever during the first through third course of R-CHOP, from the fourth course, he repeatedly demonstrated fever over 38°C for about one week after each course of chemotherapy, despite the absence of neutropenia.

POEMS syndrome complicated by follicular lymphoma.

A 59-year-old woman presented with ascites and intraperitoneal lymph node swelling. Pathological examination of the lymph node revealed follicular lymphoma. After a lymph node biopsy, she developed atypical genital bleeding, multiple endocrine disorders, polyneuropathy with a high plasma level of vascular endothelial growth factor (VEGF), and was diagnosed with POEMS syndrome.

[A case of primary adenocarcinoma of small intestine with multiple liver metastases successfully treated with mFOLFOX6].

A 60-year-old man was referred to our hospital since his stool examination was positive for occult blood. Colonoscopy showed a tumor of Bauhin's valve and terminal ileum. Biopsy of the tumor was performed and pathological examination revealed adenocarcinoma.

Diffuse large B-cell lymphoma with massive portal vein tumor thrombosis in a patient with alcoholic cirrhosis: a case report and literature review.

We describe a case of diffuse large B-cell lymphoma with massive portal vein tumor thrombosis in a patient with alcoholic cirrhosis. The tumor was detected only in the intrahepatic portal vein and the spermatic cord by FDG-PET/CT. Percutaneous liver biopsy and orchiectomy were performed and histological examination revealed diffuse large B-cell lymphoma.
