Regarding the practical farming of Litopenaeus vannamei, the deterioration of water quality from intensive culture systems and environmental pollution is a common but troublesome problem in the cultivation of this species. The toxicities that result from deteriorating water quality, such as that from ammonia stress, have lethal effects on juvenile shrimp and can increase their susceptibility to pathogens. The toxicity of ammonia plays an important role in the frequently high mortality during the early stage on shrimp farms...

BACKGROUND: Post-tonsillectomy pain is 1 of the most intense postoperative pain conditions. However, optimal and sufficient postoperative analgesic treatment remains unclear. We investigated the effect of topical ropivacaine for post-tonsillectomy pain in 160 adult outpatient surgery patients over 2 postoperative weeks. METHODS: At the end of tonsillectomy, 2 swabs soaked in either 1% ropivacaine or saline were packed into the tonsillar beds for 5 minutes. We used ibuprofen and a combination of acetaminophen (500 mg)-codeine (30 mg) tablets as postoperative analgesics for 2 weeks...

There is evidence that noninvasive brain stimulation (NIBS), and especially transcranial direct current stimulation (tDCS), can improve some cognitive functions, at least temporarily. However, as the improvement only applies to some "lucky" people, it may raise ethical, social and legal issues related to fairness in selective contexts (exams, competitions, job interviews). In this regard, an important element tends to be overlooked: the variability in individual response to tDCS in particular. If intensive study or practice and massive doses of chemical enhancers can have slightly different effects over different people, tDCS can sometimes be completely ineffective...

The Athabasca Oil Sands Region (AOSR) has been intensely developed for industrial bitumen extraction and upgrading since the 1980s. A paucity of environmental monitoring prior to development raises questions about baseline conditions in freshwater systems in the region and ecological responses to industrial activities. Further, climatic changes prompt questions about the relative roles of climate and industry in shaping aquatic ecosystems through time. We use aquatic bioindicators from multiple trophic levels, concentrations of petrogenic contaminants (dibenzothiophenes), and spectrally-inferred chlorophyll-a preserved in well-dated sediments of a closed-basin, shallow lake ~50km away from the main area of industry, in conjunction with climate observations, to assess how the biotic assemblages of a typical AOSR lake have changed during the past ~75years...

Interest in phosphorus (P) recovery and reuse has increased in recent years as supplies of P are declining. After use, most of the P remains in wastewater, making Wastewater Treatment Plants (WWTPs) a vital part of P recycling. In this work, a new sludge management operation was studied by modeling in order to recover P in the form of struvite and minimize operating problems due to uncontrolled P precipitation in WWTPs. During the study, intensive analytical campaigns were carried out on the water and sludge lines...

Wetlands are important ecosystems characterized by redoximorphic environments producing typical soil forming processes and organic carbon accumulation. Assessments and management of these areas are dependent on knowledge about soil characteristics and variability. By reflectance spectroscopy, information about soils can be obtained since their spectral behaviors are directly related to their chemical, physical, and mineralogical properties reflecting the pedogenetic processes and environment conditions. Our aims were: (a) to characterize the main soil classes of wetlands regarding their spectral behaviors in VIS-NIR-SWIR (350-2500 nm) and relate them to pedogenesis and environmental conditions, (b) to determine spectral ranges (bands) with greater expression of the main soil properties, (c) to identify spectral variations and similarities between hydromorphic soils from wetlands and other soils under different moisture conditions, and (d) to propose spectral models to quantify some chemical and physical soil properties used as environmental quality indicators...

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only treatment with a curative potential for myelodysplastic syndrome (MDS) patients. Allo-HSCT has substantial risks, particularly in the elderly, and its role for older MDS patients has yet to be defined. METHODS: We analyzed 88 MDS patients aged ≥ 60 years with allo-HSCT after reduced intensity conditioning regimens over the last decade. The study cohort had high risk features; 47 of 88 (53...

Agricultural land use results in multiple stressors affecting stream ecosystems. Flow reduction due to water abstraction, elevated levels of nutrients and chemical contaminants are common agricultural stressors worldwide. Concurrently, stream ecosystems are also increasingly affected by climate change. Interactions among multiple co-occurring stressors result in biological responses that cannot be predicted from single-stressor effects (i.e. synergisms and antagonisms). At the ecosystem level, multiple-stressor effects can be further modified by biotic interactions (e...

Sialic acids play an important role in numerous cell adhesion processes and sialylation levels are known to be altered under certain pathogenic conditions such as cancer. Metabolic glycoengineering with mannosamine derivatives is a convenient way to introduce non-natural chemical reporter groups into sialylated glycoconjugates offering the opportunity to label sialic acids using bioorthogonal ligation chemistry. The labeling intensity not only depends on the rate of the ligation reaction but also on the extent to which the natural sialic acids are replaced by the modified ones, i...

Sulfatases catalyze the hydrolysis of sulfate esters that are present in a range of biomolecules. This is an important step in several biological processes such as cellular degradation, hormone regulation, and cell signaling. We have developed a new activity-based sulfatase probe (probe 1) that generates a fluorescent N-methylisoindole upon hydrolysis by sulfatase. Because of the autoxidation of N-methylisoindole, the sulfatase activity was also tested under reducing conditions, containing either glutathione (GSH) or tris(2-carboxyethyl)phosphine (TCEP), exhibiting little change in kinetic parameters compared to non-reducing conditions...

On August 1, 2001, Korey Stringer, a Pro Bowl offensive tackle for the Minnesota Vikings, became the first and to date the only professional American football player to die from exertional heat stroke (EHS). The death helped raise awareness of the dangers of exertional heat illnesses in athletes and prompted the development of heat safety policies at the professional, collegiate, and interscholastic levels. Despite the public awareness of this death, no published study has examined in detail the circumstances surrounding Stringer's fatal EHS...

Transient osteoporosis of the hip (TOH) is a temporary clinical condition of unknown etiology which usually resolves with conservative therapy though may be complicated by fracture or progression to avascular necrosis (AVN). TOH may be slightly more prevalent in men but when it occurs in women, it is most often seen in the latter part of pregnancy. Though fracture is a rare complication of TOH when it occurs, it is most often associated with TOH occurring in pregnancy. Magnetic resonance imaging (MRI) is the best method to diagnosis TOH...

The Amyloid Precursor Protein (App) plays a crucial role in Alzheimer disease (AD) via the production and deposition of toxic β-amyloid peptides. App is heavily expressed in neurons where the vast majority of studies investigating its function have been carried out, while almost nothing is known about its function in glia, where it is also expressed, and can potentially participate in the regulation of neuronal physiology. In this report, we investigated whether Appl, the Drosophila homolog of App, could influence sleep-wake regulation when its function is manipulated in glial cells...

Membrane fouling is considered the major limitation of membrane bioreactors (MBRs). This paper provides an overview on fouling mitigation in MBRs using granular materials. Adsorbents addition extends filtration period, improves critical flux as well as sludge properties (increased flocs size, reduced soluble EPS, improved dewaterability). However, determination of optimal dosages of adsorbents is needed to balance cost savings from fouling mitigation versus cost of adsorbents and sludge handling. The abrasion from granular media reduces cake layer formation, extends membrane filtration period, increases flux (∼20-30%), and reduces aeration intensity by 50%...
