Antinociceptive and Anti‐inflammatory Effect of Nicandrin B Isolated From Datura ferox in Zebrafish

Chemistry &Biodiversity, EarlyView.
ABSTRACT Nicandrin B (Nic B), a withanolide isolated from Datura ferox leaves, was investigated for its antinociceptive and anti‐inflammatory effects in adult zebrafish (Danio rerio). Animals treated with Nic B (4, 20, and 40 mg/kg) showed no toxicity and maintained normal locomotor activity.

Changes in the algal composition, bacterial metabolic activity and element content of biofilms developed on artificial substrata in the early phase of colonization [PDF]

, 2007
Changes in the algal composition and metabolic profiles of bacterial communities as well as the inorganic components were studied on artificial substrata during the early phase of biofilm formation under laboratory conditions in September 2002 and 2003 ...

Bahaman patch reefs: Numerous and neglected

The Depositional Record, EarlyView.
Abstract Phanerozoic patch reefs are extensively studied because they are abundant and are potential reservoirs for valuable fluids. In contrast, geologic studies of modern reefs have largely focused on platform margins, leaving patch reefs comparatively neglected. What conditions favour patch‐reef development?

Beneath the Surface: Investigating Perovskite Solar Cells Under Water

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Underwater Performance of Perovskite Solar Cells Demonstrated robust encapsulation: rigorous corrosion testing and lead leakage analysis of a damaged, immersed device, confirming the encapsulation's durability. Enhanced power conversion efficiency observed underwater: This improvement is attributed to the optical and cooling effects of the water, with ...

Pyriproxyfen Disrupts the Ongoing Spermatogenesis Wave in Danio rerio Potentially Mediated by Voltage‐Dependent Calcium Channels and Protein Kinase C

Journal of Applied Toxicology, EarlyView.
ABSTRACT Pyriproxyfen (PPX) is an analog of the juvenile hormone from insects. Following our previous studies, for the ex vivo short‐term effect, we chose 10−9 M pyriproxyfen to analyze the morphology of spermatogenesis wave cells. In silico docking and ADMET (Absorption, Distribution, Metabolism, Excretion, Toxicity) studies were carried out to ...

Interactions between parental traits, environmental harshness and growth rate in determining telomere length in wild juvenile salmon [PDF]

, 2016
A larger body size confers many benefits, such as increased reproductive success, ability to evade predators and increased competitive ability and social status. However, individuals rarely maximise their growth rates, suggesting that this carries costs.

Seagrasses under stress: Independent negative effects of elevated temperature and light reduction at multiple levels of organization

Limnology and Oceanography, EarlyView.
Abstract Seagrasses are important foundation species, which support coastal biodiversity and provide socioeconomic benefits. However, seagrasses are threatened by anthropogenic changes, including the elevated temperature associated with marine heatwaves (MHWs) and light limitation from eutrophication or increased sedimentation.

Interspecific association of brown trout (Salmo trutta) with non-native brook trout (Salvelinus fontinalis) at the fry stage [PDF]

, 2017
The introduction of non-native brook trout (Salvelinus fontinalis) in Europe has led to displacement and decreasing populations of native brown trout (Salmo trutta).

Embedding a multichannel ion‐sensitive field‐effect transistor‐pH sensor array in marine sediments: a new approach for continuous in situ pH monitoring

Limnology and Oceanography: Methods, EarlyView.
Abstract Human activities have significantly increased carbon dioxide emissions, leading to global warming and ocean acidification, which threaten marine ecosystems, including coral reefs with high biodiversity. Coral reef maintenance relies on a balance between calcium carbonate formation and dissolution. Among the processes, sandy sediments, covering
