However, the specific impacts of BPA exposure on clam gills remain largely unexplored. To investigate the effects of BPA on energy metabolism and apoptosis in Meretrix petechialis gills, clams were exposed to varying concentrations of BPA (1, 10, and 100 μg/L) for 21 days.

Fatty Acid Profiles Linked to Organohalogen Exposure in Cetaceans from the Northern South China Sea.

Increasing evidence suggests that organohalogen contaminants (OHCs) could disrupt lipid metabolism in organisms, prompting consideration of fatty acids (FAs) as biological tools for assessing chemical stress in biological systems. This study examined 87 OHCs and 32 FAs in two sentinel cetacean species─Indo-Pacific humpback dolphins ( = 128) and Indo-Pacific finless porpoises ( = 26)─from the northern South China Sea (NSCS), a global hotspot for OHCs. Our results revealed higher OHC levels in these cetaceans than global averages.

Infectious bursal disease virus affecting interferon regulatory factor 7 signaling through VP3 protein to facilitate viral replication.

Interferon regulatory factor 7 (IRF7)-mediated type I interferon antiviral response is crucial for regulating the host following viral infection in chickens. Infectious bursal disease virus (IBDV) is a double-stranded RNA virus that induces immune suppression and high mortality rates in chickens aged 3-6 weeks. Previous studies have shown that IBDV infection antagonizes the type I interferon production to facilitate viral replication in the cell, and IRF7 signaling might play an important role.

An Au-Ag@Au fiber surface plasmon resonance sensor for highly sensitive detection of fluoroquinolone residues.

However, how warming mediates shrimp health remains poorly understood.

Temperature seasonality regulates organic carbon burial in lake.

Organic carbon burial (OCB) in lakes, a critical component of the global carbon cycle, surpasses that in oceans, yet its response to global warming and associated feedbacks remains poorly understood. Using a well-dated biomarker sequence from the southern Tibetan Plateau and a comprehensive analysis of Holocene total organic carbon variations in lakes across the region, here we demonstrate that lake OCB significantly declined throughout the Holocene, closely linked to changes in temperature seasonality. Process-based land surface model simulations clarified the key impact of temperature seasonality on OCB in lakes: increased seasonality in the early Holocene saw warmer summers enhancing ecosystem productivity and organic matter deposition, while cooler winters improved organic matter preservation.

Molecular dynamics and factors governing recalcitrance of dissolved organic matter: Insights from laboratory incubation and ultra-high resolution mass spectrometry.

The oceanic dissolved organic matter (DOM) reservoir is one of Earth's largest carbon pools, yet the factors contributing to its recalcitrance and persistence remain poorly understood. Here, we employed ultra-high resolution mass spectrometry (UHRMS) to examine the molecular dynamics of DOM from terrestrial, marine and mixed sources during bio-incubation over weekly, monthly, and one year time spans. Using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS), we classified DOM into three distinct categories (Consumed, Resistant and Product) based on their presence or absence at the start and end of the incubation.

Sparse deconvolution beamforming with non-negative L1-αL2 regularization for acoustic source localization.

This letter proposed a sparse deconvolution localization method (FFT-L1ML2) driven by non-convex L1-αL2 regularization that more closely approximates the ideal L0 norm. It is an alternative that explores the sparse structure of sound sources to enhance localization accuracy, while the original sparse deconvolution beamforming lacks a sufficiently accurate sparse description. An optimization solver composed of forward gradient descent and backward proximal operator is then developed for the FFT-L1ML2 model to reconstruct the beamforming map.

Cloud radiative effect dominates variabilities of surface energy budget in the dark Arctic.

Climate models simulate a wide range of temperatures in the Arctic. Here we investigate one of the main drivers of changes in surface temperature: the net surface heat flux in the models. We show that in the winter months of the dark Arctic, there is a more than two-fold difference in the net surface heat fluxes among the models, and this difference is dominated by the downward infrared radiation from clouds.
