Colloidal bismuth subcitrate (CBS; De-Nol) exhibits gastroprotective properties in experimental animals and enhances the healing of chronic gastroduodenal ulcers, but the mechanisms of these actions have not been entirely elucidated. The present study was designed to determine whether epidermal growth factor (EGF), which also has gastroprotective and ulcer healing properties, contributes to the...

BACKGROUND The nociception level (NoL) index is an index of nociception based on nonlinear combination of heart rate, heart rate variability, photoplethysmograph wave amplitude, skin conductance, skin conductance fluctuations, and their time derivatives. The authors evaluated the abilities of the NoL index and other measures of nociception to discriminate between noxious and nonnoxious stimuli,...

This paper was designed to investigate the phenotypic characterization of Nanshi Oral Liquid (NOL) alters metabolic signatures of the 'Kidney Yang Deficiency syndrome' (KYDS). Urine metabolites were profiled by UPLC-ESI-Q-TOF-HDMS. The significantly changed metabolites such as xanthurenic acid, 4,8-dihydroxyquinoline, 3-methyldioxyindole, 4,6-dihydroxyquinoline, kynurenic acid, hippuric acid, t...

This double blind randomised study tested the effectiveness of colloidal bismuth subcitrate (De-Nol) in non-ulcer dyspepsia (NUD) and if any benefit is associated with clearance of Campylobacter pylori (C pylori) from the gastric mucosa. Sixty six patients with dyspepsic symptoms, normal abdominal ultrasound, and upper GI endoscopy, were randomly allocated to placebo or De-Nol for eight weeks. ...

This Application Note demonstrates the separation of eight tocopherol and tocotrienol compounds by supercritical fl uid chromatography (SFC) using the Agilent 1260 Infi nity Analytical SFC system. Calibration curves were generated for all compounds, and a real-life virgin olive oil sample was analyzed. The limits of detection and quantifi cation (LOD and LOQ) were determined as well as relative...

This study compares the gastroprotective effects of colloidal bismuth subcitrate (De-Nol) with those of sucralfate and a methylated analogue of prostaglandin E2 (PGE2) against acute gastric lesions induced by acidified aspirin and absolute ethanol in rats. Both De-Nol and sucralfate given orally prevented dose dependently the formation of gastric lesions by these ulcerogens, De-Nol being, respe...

The properties of graphene can vary as a function of the number of layers (NOL). Controlling the NOL in large area graphene is still challenging. In this work, we demonstrate a picosecond (ps) laser thinning removal of graphene layers from multi-layered graphene to obtain desired NOL when appropriate pulse threshold energy is adopted. The thinning process is conducted in atmosphere without any ...

This study was designed to determine the effects of colloidal bismuth subcitrate De-Nol on gastric HCO3- secretion in 24 healthy subjects and on gastric and duodenal HCO3- secretion in dogs with gastric and duodenal fistulae. Alkaline secretion was measured after pretreatment with ranitidine to abolish the H+ secretion using a constant perfusion aspiration system and back titration of the perfu...

During natural or dark-induced senescence, chlorophyll degradation causes leaf yellowing. Recent evidence indicates that chlorophyll catabolic enzymes (CCEs) interact with the photosynthetic apparatus; for example, five CCEs (NYC1, NOL, PPH, PAO and RCCR) interact with LHCII. STAY-GREEN (SGR) and CCEs interact with one another in senescing chloroplasts; this interaction may allow metabolic chan...
