Discovering novel neuroactive drugs through high-throughput behavior-based chemical screening in the zebrafish

Most neuroactive drugs were discovered through unexpected behavioral observations. Systematic behavioral screening is inefficient in most model organisms. But, automated technologies are enabling a new phase of discovery-based research in central nervous system (CNS) pharmacology. Researchers are using ...

Detecting In Situ Copepod Diet Diversity Using Molecular Technique: Development of a Copepod/Symbiotic Ciliate-Excluding Eukaryote-Inclusive PCR Protocol

Knowledge of in situ copepod diet diversity is crucial for accurately describing pelagic food web structure but is challenging to achieve due to lack of an easily applicable methodology. To enable analysis with whole copepod-derived DNAs, we developed a copepod-excluding 18S rDNA-based PCR protocol. ...

Obesity and obesity-associated cardiometabolic risk factors in indigenous Nenets women from the rural Nenets Autonomous Area and Russian women from Arkhangelsk city

Background The prevalence of obesity and obesity-related conditions varies by population groups. Indigenous women of the circumpolar north are believed to be at high risk of obesity. Objective We studied, first the obesity prevalence in indigenous Arctic women, Nenets, compared to urban Russian women. ...

Fine-scale population epigenetic structure in relation to gastrointestinal parasite load in red grouse (Lagopus lagopus scotica)

Epigenetic modification of cytosine methylation states can be elicited by environmental stresses and may be a key process affecting phenotypic plasticity and adaptation. Parasites are potent stressors with profound physiological and ecological effects on their host, but there is little understanding ...

Analyzing Cold Tolerance Mechanism in Transgenic Zebrafish (Danio rerio)

Low temperatures may cause severe growth inhibition and mortality in fish. In order to understand the mechanism of cold tolerance, a transgenic zebrafish Tg (smyd1:m3ck) model was established to study the effect of energy homeostasis during cold stress. The muscle-specific promoter Smyd1 was used to ...

Effects of Increased CO2 on Fish Gill and Plasma Proteome

Ocean acidification and warming are both primarily caused by increased levels of atmospheric CO2, and marine organisms are exposed to these two stressors simultaneously. Although the effects of temperature on fish have been investigated over the last century, the long-term effects of moderate CO2 exposure ...

Increased Noise Levels Have Different Impacts on the Anti-Predator Behaviour of Two Sympatric Fish Species

Animals must avoid predation to survive and reproduce, and there is increasing evidence that man-made (anthropogenic) factors can influence predator−prey relationships. Anthropogenic noise has been shown to have a variety of effects on many species, but work investigating the impact on anti-predator ...

Effect of sulfate on low-temperature anaerobic digestion

The effect of sulfate addition on the stability of, and microbial community behavior in, low-temperature anaerobic expanded granular sludge bed-based bioreactors was investigated at 15°C. Efficient bioreactor performance was observed, with chemical oxygen demand (COD) removal efficiencies of >90%, ...

Chemical and biological work-related risks across occupations in Europe: a review

Background Work-related health inequalities are determined to some extent by an unequal exposure to chemical and biological risk factors of disease. Although their potential economic burden in the European Union (EU-25) might be substantial, comprehensive reviews focusing on the distribution of these ...

Aeratore rotante per acquari e stagni

L’invenzione riguarda un aeratore (10) per acquari e stagni in cui è presente una girante (60) azionata da un motore elettrico (20) avente una prima entrata (246, 347) per l'aspirazione di acqua, una seconda entrata (44) per l'aspirazione di aria e un'uscita (254) da cui fuoriesce il flusso di acqua ...

Climate improver for ponds, and pond-filter system

A climate improver for ponds, having fibres (1) which form a settling surface area for bacteria (17), and having an air-admission element (3) for supplying air, is constructed such that the air-admission element (3) is designed for generating a water flow along the fibres (1) in the upward direction, ...

Artifical habitat in polyhedron form for crustaceans, and use

Known artificial habitats in polyhedron form for crustaceans on aquatic soft floors having independent stability and structured surfaces either have an extremely small structure at the transition to the aquatic soft floor or no such structure. However, crabs are hard floor animals and settle in soft ...

Fishing lure

A fishing lure for trolling and casting. According to a preferable embodiment the lure of includes a body part having tracks formed in each side of the lure's body part, a hook for each track arranged to be movable along the track, latching elements for fastening the hooks to their activated state, ...

Fishing bait

Described are bait compositions (1) for use in fishing, comprising a plurality of integrally formed artificial creatures (2). The artificial creatures may comprise one or more of artificial maggots, grubs, larvae, worms, meal worms and/or other commonly found natural water born creatures. Also described ...

Support system

A support system (1) for traffic support of ships (20a, 20b, 21a, 21b), having AIS ship reception units for receiving AIS radio signals containing ship traffic data, is characterized in that at least one flight object (2) is provided, comprising at least one AIS flight transmission unit (3), which is ...

Traditional uses of plants in a rural community of Mozambique and possible links with Miombo degradation and harvesting sustainability

Background Miombo woodlands play an important role in the livelihood of people living in sub-equatorial African countries, contributing to satisfy basic human needs such as food, medicine, fuelwood and building materials. However, over-exploitation of plant resources and unsustainable harvest practices ...

Discontinuity of Human Presence at Atapuerca during the Early Middle Pleistocene: A Matter of Ecological Competition?

Increasing evidence suggests that the European human settlement is older than 1.2 Ma. However, there is a fierce debate about the continuity or discontinuity of the early human settlement of Europe. In particular, evidence of human presence in the interval 0.7−0.5 Ma is scarce in comparison with evidence ...

Compositions for oral administration to animals, production methods thereof and uses of same

The present invention relates to a solid appetising composition, the use thereof and the production method of same, said composition comprising in relation to the total weight thereof: 5 to 30 wt.-%, preferably 8 to 20 wt.-%, of at least one fat, selected from a liquid oil, a fatty substance, a wax ...

On the Fourth Diadema Species (Diadema-sp) from Japan

Four long-spined sea urchin species in the genus Diadema are known to occur around the Japanese Archipelago. Three species (D. savignyi, D. setosum, and D. paucispinum) are widely distributed in the Indo-Pacific Ocean. The fourth species was detected by DNA analysis among samples originally collected ...

Transcriptome Analysis of the Mud Crab (Scylla paramamosain) by 454 Deep Sequencing: Assembly, Annotation, and Marker Discovery

In this study, we reported the characterization of the first transcriptome of the mud crab (Scylla paramamosain). Pooled cDNAs of four tissue types from twelve wild individuals were sequenced using the Roche 454 FLX platform. Analysis performed included de novo assembly of transcriptome sequences, functional ...
