Seasonal patterns and controls on net ecosystem CO2 exchange in a boreal peatland complex [PDF]

, 1998
We measured seasonal patterns of net ecosystem exchange (NEE) of CO2 in a diverse peatland complex underlain by discontinuous permafrost in northern Manitoba, Canada, as part of the Boreal Ecosystems Atmosphere Study (BOREAS).

SR‐B1‐Mediated Transplacental Transfer of Hydrophobic Toxicants Disrupts Fetal Development During Barriergenesis

Advanced Science, EarlyView.
This study maps the spatiotemporal distribution of hydrophobic toxicants and endogenous metabolites in the developing placenta and fetus. By integrating mass spectrometry imaging with snRNA‐seq, we identify SR‐B1 as a key transporter driving early‐gestation xenobiotic transfer and reveal a critical exposure window associated with persistent fetal ...

Long-term fire effects of the drained open fen on organic soils

Archives of Environmental Protection, 2017
Fire has considerable impact on vegetation and organic soils properties. As we observed that the differences between vegetation of burnt and unburnt areas on the rich fen are visible 11 years after the fire, we assumed that the post-fire changes are long

An Immunconjugate Vaccine Alters Distribution and Reduces the Antinociceptive, Behavioral and Physiological Effects of Fentanyl in Male and Female Rats

Pharmaceutics, 2022
Fentanyl (FEN) is a potent synthetic opioid associated with increasing incidence of opioid use disorder (OUD) and fatal opioid overdose. Vaccine immunotherapy for FEN-associated disorders may be a viable therapeutic strategy.

A Testis‐Specific Aralkylamine N‐Acetyltransferase Regulates Dimorphic Sperm Function and Male Fertility in Moths

Advanced Science, EarlyView.
We identify a Lepidoptera‐conserved testis‐specific arylalkylamine N‐acetyltransferase (LTNAT) that governs male moth fertility via a novel mechanism. LTNAT loss disrupts eupyrene sperm mitochondrial derivatives and impairs apyrene sperm motility, offering a safe molecular target for innovative pesticides and genetic pest control.

Spatial Transcriptomics of TMJ Reveals a Remodeling Fibroblast‐Immune Microenvironment Driving Arthritis Pain

Advanced Science, EarlyView.
Spatial transcriptomics reveals a remodeled fibroblast‐immune microenvironment in the temporomandibular joint (TMJ) during arthritis. By combining seqFISH with genetic mouse models, this study uncovers TMJ spatial cell atalas, macrophage‐fibroblast crosstalk, and cytokine signaling pathways driving TMJ inflammation and pain.
