Investigation of the Supercapacitor Performance of NiCoAl(OH)₂ from the Co-Precipitation Method.

Herein, NiCoAl(OH)₂ materials, a by-product in the preparation of the precursor of cathode materials for lithium ion batteries, were employed as supercapacitor electrodes. The reaction time was changed from 2 to 48 h to produce hydroxide products, which were analyzed using physical and electrochemical methods. The hydroxide material reacted for 2 h exhibited a good average particle strength of 34.

Interobserver variability and accuracy of high-definition endoscopic diagnosis for gastric intestinal metaplasia among experienced and inexperienced endoscopists.

Accurate diagnosis of gastric intestinal metaplasia is important; however, conventional endoscopy is known to be an unreliable modality for diagnosing gastric intestinal metaplasia (IM). The aims of the study were to evaluate the interobserver variation in diagnosing IM by high-definition (HD) endoscopy and the diagnostic accuracy of this modality for IM among experienced and inexperienced endoscopists. Selected 50 cases, taken with HD endoscopy, were sent for a diagnostic inquiry of gastric IM through visual inspection to five experienced and five inexperienced endoscopists.

A fatal case of hepatitis B virus (HBV) reactivation during long-term, very-low-dose steroid treatment in an inactive HBV carrier.

Hepatitis B virus (HBV) may be reactivated after chemotherapy or immunosuppressive therapy, and therefore administration of antiviral agents before such treatment is recommended. Most reported cases of reactivation are associated with high doses of immunosuppressive agents or combination therapy. We present a case of a previously inactive HBV carrier with an acute severe flare-up during a long-term, very-low-dose (2.

The Miss Rate for Colorectal Adenoma Determined by Quality-Adjusted, Back-to-Back Colonoscopies.

Background/aims: Colonoscopy is considered to be the gold standard for detecting adenomatous polyps. Polyps are missed during colonoscopic examination at a rate that varies from 6% to 27%. The adenoma miss rate affects colonoscopic surveillance intervals and procedural quality.

Graduated injection needles and snares for polypectomy are useful for measuring colorectal polyp size.

Background: Accurate measurement of polyp size during colonoscopy is important; however, visual estimation of polyp size is inaccurate, and it is cumbersome to use additional accessories to measure polyp size whenever polyps are detected.

Aims: To evaluate the accuracy and usefulness of graduated devices that can also be used for polypectomy.

Methods: The ends of the outer sheath of the injection needles and snares were marked at intervals of 5mm (total 30mm).

The timing of bowel preparation is more important than the timing of colonoscopy in determining the quality of bowel cleansing.

Aims: We aimed to compare the quality of bowel preparation and cecal intubation rates between morning and afternoon colonoscopies and to evaluate the difference in quality of bowel preparation according to the intervals between starting and ending intake of bowel preparation agent and the initiation of colonoscopy.

Methods: In this prospective study, 300 outpatients were instructed to drink PEG solution starting either at 5:00 a.m.

[Fulminant hepatic failure with hepatitis B virus reactivation after rituximab treatment in a patient with resolved hepatitis B].

It is well known that the reactivation of hepatitis B virus (HBV) may occur as an acute hepatitis after chemotherapy or immunosuppressive therapy. Although most of these cases have been reported in HBsAg-positive patients, there have been a few reports of HBV reactivation in HBsAg-negative patients. There have been concerns for the need to screen the reactivation as well as anti-viral prophylaxis in HBsAg-negative patients with possible HBV occult infection who are planning to undergo chemotherapy or immunosuppressive therapy.

[A case of extranodal histiocytic sarcoma of stomach mimicking gastric adenocarcinoma].

Histiocytic sarcoma is a rare malignant neoplasm that originates from a histiocytic hematopoietic lineage characterized by histiocytic differentiation and its corresponding immunophenotypic features. Patients with histiocytic sarcoma usually have a poor prognosis due to its aggressive clinical behavior. Here we report a rare case of extranodal histiocytic sarcoma of the stomach which was confirmed through immunohistochemical staining.

Chest wall metastasis from unknown primary site of hepatocellular carcinoma.

Previous reports of a solitary metastatic hepatocellular carcinoma have been rare. Because this tumor has a different treatment modality and prognosis, an accurate differential diagnosis is essential. Here we report a rare case of a solitary chest wall metastasis from unknown primary site of hepatocellular carcinoma.

Acute pancreatitis due to hypertriglyceridemia: report of 2 cases.

Hypertriglyceridemia (HTG) is a rare but well known cause of acute pancreatitis (AP), which can be a life- threatening complication if the degree of HTG is severe enough. It might be primary in origin or secondary to alcohol abuse, diabetes mellitus, pregnancy, or drugs. A serum triglyceride (TG) level of more than 1,000 to 2,000 mg/dL in patients with type I, IV, or V hyperlipidemia (Fredrickson's classification) is the identifiable risk factor.

Adult-onset Still's disease with disseminated intravascular coagulation and multiple organ dysfunctions dramatically treated with cyclosporine A.

Severe systemic manifestations of adult onset Still's disease (AOSD) are often fatal and occasionally related to hemophagocytic syndrome (HS). We describe the case of a 49-yr-old woman with AOSD presenting with non-remitting high fever, confusion, jaundice, hepatosplenomegaly, serositis, azotemia, pancytopenia, coagulopathy with disseminated intravascular coagulation (DIC), hyperferritinemia, acute acalculous cholecystitis and ileocolitis noted in computed tomographic images. The patient had a history of herpes zoster developed prior to the admission, but there is no history of diarrhea or abdominal pain.
