Current approaches to protect biodiversity by establishing protected areas usually gloss over water pollution as a threat. Our objective was to determine the longitudinal and seasonal distribution of perfluoroalkyl acids (PFAAs) in water column and sediments from a wastewater dominated stream that enters preservation areas. Water samples were collected along the longitudinal section (six sites,...

Halotolerant and halophilic melanized fungi were recently described in hypersaline waters. A close study of the sterol composition of such fungi, namely Hortaea werneckii, Alternaria alternata, Cladosporium sphaerospermum, Cladosporium sp., and Aureobasidium pullulans revealed the dominance of ergosterol and the presence of 29 intermediates of its biosynthesis pathway. The presence or absence o...

PURPOSE The optimal delivery medium for esomeprazole magnesium enteric-coated pellets dispersed in various concentrations of Ora-Plus suspension through commonly used nasogastric and gastrostomy tubes using a previously used standardized in vitro protocol was studied. METHODS The study was conducted in two phases. In phase A, 60 size 14 French nasogastric tubes were used to compare esomeprazo...

Following field observations of increased photosynthesis at increased rates of sediment flushing in sandy sediments, we conducted a series of laboratory experiments to elucidate the mechanism behind these observations. Column experiments in which water was pumped though sand at rates ranging from 0 to 613 L m22 d21 showed that carbon (C) fixation, as measured using carbon-14 (14C) incorporation...

Understanding the links between climate change and human migration and culture is an important theme in Quaternary archaeology. While oxygen and hydrogen stable isotopes in high-latitude ice cores provide the ultimate detailed record of palaeoclimate extending back to the Middle Pleistocene, groundwater can act as a climate archive for areas at lower latitudes, permitting a degree of calibratio...

AIMS To compare the effects of early and delayed sodium supplementation on body composition and body water compartments during the first two weeks of postnatal life. METHODS Preterm infants of 25-30 weeks' gestation were stratified and randomly assigned according to gender and gestational age, to receive a sodium intake of 4 mmol/kg/day beginning either on the second day after birth or when w...

BACKGROUND Ventilation tube insertion is a common treatment for children with persistent otitis media with effusion. Parents are concerned about the morbidity of this procedure and the influence of ventilation tubes on daily activities. Permissibility of swimming is a question that is most often asked. The aim of this study was to investigate the possibility of water penetration through ventila...

In December 2012, an outbreak of acute gastrointestinal illness occurred in a geographical distinct area in Denmark covering 368 households. A combined microbiological, epidemiological and environmental investigation was initiated to understand the outbreak magnitude, pathogen(s) and vehicle in order to control the outbreak. Norovirus GII.4 New Orleans 2009 variant was detected in 15 of 17 indi...

The effect of warm water dip in combination with irradiation on quality of fresh-cut green onions was studied. Fresh-cut green onions were treated with and without warm water (50 °C for 20 s) and packaged prior to irradiation at 0, 0.5, 1.0, and 1.5 kGy, then stored at 4 °C for 14 d. Color, texture, decay percentage, electrolyte leakage, sensory qualities, and total aerobic count (TAC) were mea...
