Ling-Yu Hsieh, Yi-Rong Chen, Mei-Chun Lu
BACKGROUND: Use of analgesics is the most common method to alleviate the pain induced by chest tube removal (CTR), but patient response to medication can vary and may not be achieved complete relaxation. This study was to determine the effectiveness of cold application in combination with standard analgesic administration before CTR on CTR-induced pain. METHODS: A prospective, randomized, single-blind, sham-controlled study was conducted. In addition to the same routine care, subjects in the experimental group (n = 30) received cold application of 600-g ice packs 15 minutes before CTR, whereas subjects in the sham group (n = 30) received tap water packs...

The present work reports the interaction of various vitamin B6 cofactors with the red emitting glutathione stabilized copper nanoclusters (GSH-CuNCs). Addition of pyridoxamine (PM) resulted a new turn-on band at 410nm due to the possible adsorption over the surface of GSH-CuNCs. The nano-assembly PM-GSH-CuNCs was applied for the selective detection of nitro-aromatic compounds. Upon addition of picric acid (PA), the fluorescence of PM-GSH-CuNCs was selectively quenched at 410nm and ~ 625nm among the other tested nitro-aromatic compounds...

Immunochromatographic strips (ICSs) are inexpensive, simple, portable, and robust, and therefore have many uses in the medicinal, agricultural, and environmental industries. For detection of small molecules, current ICSs are competitive format (competitive ICSs, CICSs), which only offer a turn-off readout mode, and therefore lead to low sensitivity when evaluating results by the naked eye. To overcome this problem, we report a turn-on CICSs that relies on the ability of gold nano-stars (AuNSs) quenching the signal of quantum dots (QDs)...

The herbicide bentazone is recalcitrant in aquifers and is therefore frequently detected in wells used for drinking water production. However, bentazone degradation has been observed in filter sand from a rapid sand filter at a waterworks with methane-rich groundwater. Here, the association between methane oxidation and removal of bentazone was investigated with a methanotrophic enrichment culture derived from methane-fed column reactors inoculated with that filter sand. Several independent lines of evidence obtained from microcosm experiments with the methanotrophic enrichment culture, tap water and bentazone at concentrations below 2 mg/L showed methanotrophic co-metabolic bentazone transformation: The culture removed 53% of the bentazone in 21 days in presence of 5 mg/L of methane, while only 31% was removed in absence of methane...

The category of "leafy vegetables" comprises a wide range of plants, including cabbage, lettuce, leeks, spinach, Swiss chard, and kale, and it forms a significant component of the human diet. Typically, leafy vegetables are low in calories and fat, are great sources of vitamins, protein, dietary fibre, minerals (including iron, calcium, and nitrates), and are rich in phytochemicals. To counter the impact of pests on vegetables, a broad variety of pesticides is used. Because of their large surface areas, leafy vegetables are expected to have high residual pesticide levels...

Except for task-specific functional MRI, the vast majority of imaging studies assessed human brain function at resting conditions. However, tracking task-specific neuronal activity yields important insight how the brain responds to stimulation. We specifically investigated changes in glucose metabolism, functional connectivity and white matter microstructure during task performance using several recent methodological advancements. Opening the eyes and right finger tapping had elicited an increased glucose metabolism in primary visual and motor cortices, respectively...

Hydrogen sulfide, a toxic gas, at low concentrations is also a biological mediator in animals. In the colon, hydrogen sulfide is produced by intestinal tissues and gut sulfur bacteria. Gut-derived molecules undergo liver metabolism. Portal hypertension is one of the most common complications contributing to the high mortality in liver cirrhosis. We hypothesized that the colon-derived hydrogen sulfide may affect portal blood pressure. Sprague-Dawley rats were maintained either on tap water (controls) or on water solution of thioacetamide to produce liver cirrhosis (CRH-R)...

The analysis of fluorine was carried out by measuring BaF(+) ions with an inductively coupled plasma tandem quadrupole mass spectrometer (ICP-QMS/QMS). After optimization, a radio frequency power of 1300 W was found to benefit for the production of BaF(+) ions while suppressing the production of BaOH3(+) ions. After optimization of the reaction cell gas, it was found that the best performance for measuring BaF(+) could be achieved at a flow rate of O2 in the range from 0.65 to 0.75 mL min(-1). The signal intensity of BaF(+) depended linearly on the concentration of Ba when it was not higher than 100 mg kg(-1)...
