Luminous bacteria in seawater around the islands of Bahrain are predominantly Vibrio harveyi and have the capability to adhere to artificial fibrous surfaces. Phytoplankton did not appear to have any specific relationship with luminous bacteria, but macroalgae were shown to possess an enhanced concentration of luminous bacteria.

Abstract The study presents monthly variations of seawater properties, monitoring water column stability and stratification over the southern shelf of the Caspian Sea which depends on collecting data. Field measurements were carried out during 13 cruises along the southern boundary of the sea. Spatial and temporal distributions of temperature, salinity and density were investigated. Monthl...

BACKGROUND The combination of seawater baths and narrowband ultraviolet B (NB-UVB) is a known treatment for psoriasis. This study evaluates two treatment regimens that combine bathing in geothermal seawater and NB-UVB therapy in comparison with NB-UVB monotherapy. METHODS Sixty-eight psoriasis patients were randomly assigned to outpatient bathing in geothermal seawater combined with NB-UVB th...

Drowning is a crucial public safety problem and is the third leading cause of accidental fatality, claiming ~372,000 lives annually, worldwide. In near-drowning patients, acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) is one of the most common complications. Approximately 1/3 of near-drowning patients fulfill the criteria for ALI or ARDS. In the present article, the curre...

BACKGROUND The regulation of mucociliary clearance is a key part of the defense mechanisms developed by the airway epithelium. If a high aggregate quality of evidence shows the clinical effectiveness of nasal irrigation, there is a lack of studies showing the intrinsic role of the different irrigation solutions allowing such results. This study investigated the impact of solutions with differen...

Axons freshly dissected from living specimens of the tropical squid Dorytheutis plei have a calcium content of 68 mumol/kg of axoplasm. Fibers stimulated at 100 impulses/s in 100 mM Ca seawater increase their Ca content by 150 mumol/kg.min; axons placed in 3 Ca (choline) seawater increase their Ca content by 12 mumol/kg.min. Axons loaded with 0.2--1.5 mmol Ca/kg of axoplasm extruded Ca with a h...

To elucidate the mechanisms associated with water absorption in the intestine, we compared drinking and intestinal water absorption in freshwater- and seawater-adapted Japanese eels, and investigated a possible involvement of aquaporin (AQP) in the absorption of water in the intestine. Seawater eels ingested more water than freshwater eels, the drinking rate being 0.02 ml kg(-1) h(-1) in fresh ...

Ion exchange properties of five different Japanese natural zeolites in seawater were examined. Sodium ions could be reduced by all zeolites, although anions, Cl(-) and SO(4)(2-), in seawater showed barely changes. Natural zeolite desalination treatment mainly depends on the ion exchange between Na(+), K(+) and Mg(2+) in seawater and Ca(2+) in natural zeolite. This study found that mordenite ...
