BACKGROUND Immersion in seawater after open chest trauma may induce acute lung injury. Higher osmotic pressure is one of the main characteristics of seawater. The effects of vascular endothelial growth factor (VEGF) on endothelial cell permeability and proliferation have been demonstrated in studies. The early responses and effects of the VEGF on acute lung injury induced by seawater immersion ...

A novel flow injection ion chromatograph (FI-IC) system has been developed to fully automate pretreatment procedures for multi-elemental analysis of trace metals in seawater by inductively coupled plasma mass spectrometer (ICPMS). By combining 10-port, 2 position and 3-way valves in the FI-IC manifold, the system effectively increase sample throughput by simultaneously processing three seawater...

[1] Records of seawater chemistry help constrain temporal variations in geochemical processes that impact the global carbon cycle and climate through Earth’s history. Here we reconstruct Cenozoic seawater Sr/Ca (Sr/Casw) using fossil Conus and turritellid gastropod Sr/Ca. Combined with an oxygen isotope paleotemperature record from the same samples, the gastropod record suggests that Sr/Casw wa...

A colorimetric pH measurement of seawater samples using a light source comprising a three light-emitting diodes (TLED) detector and meta-cresol purple (mCP) as an indicator was investigated. The molar absorption ratios (e1, e2, and e3/e2) for mCP using the TLED detector at 25°C were determined to be 0, 1.9994, and 0.1010, respectively. Next, the pH values of 2-amino-2-hydroxymethyl-1,3-propaned...

The temperature and salt dependencies of absorption by liquid water (H2O) and heavy water (D2O) were determined using a hyperspectral absorption and attenuation meter (WET Labs, AC-S). Sodium chloride (NaCl) was used as a proxy for seawater salts. There was no significant temperature (PsiT) or salt (PsiS) dependency of absorption at wavelengths <550 nm. At wavelengths >550 nm, PsiT exhibited pe...

The effects of carbon sources, seawater concentration and seawater component in a culture medium were investigated to optimize culture conditions for growth by a marine thraustochytrid Aurantiochytrium limacinum strain mh0186. Strain mh0186 could utilize D-glucose, D-fructose and D-mannose as carbon sources. Seawater concentrations between 12.5 - 200% were required for good growth, and a single...

Seawater aspiration‑induced acute lung injury (ALI) is a syndrome associated with a high mortality rate, which is characterized by severe hypoxemia, pulmonary edema and inflammation. The present study is the first, to the best of our knowledge, to analyze gene expression profiles from a rat model of seawater aspiration‑induced ALI. Adult male Sprague‑Dawley rats were instilled with seawater (4 ...

40 With increasing atmospheric CO2 concentrations, the oceans are expected to increase in acidity during the next century. Increasing ocean acidity has been shown to negatively affect many marine ecosystems, particularly calcifying organisms. We investigated acidification effects on the turtle grass communities of Little Cayman Island, British West Indies (BWI). We hypothesized that acidified s...

The efficient development of selective materials for the recovery of uranium from nuclear waste and seawater is necessary for their potential application in nuclear fuel and the mitigation of nuclear pollution. In this work, a graphene oxide/amidoxime hydrogel (AGH) exhibits a promising adsorption performance for uranium from various aqueous solutions, including simulated seawater. We show high...
