Toarcian oceanic anoxic event: An assessment of global causes using belemnite C isotope records [PDF]

, 2005
Two hypotheses have been proposed to explain simultaneous large negative excursions (up to 7% PeeDee belemnite) in bulk carbonate (delta(13)C(carb)) and organic carbon isotope records (delta(13)C(org)) from black shales marking the Toarcian oceanic ...

A ¹⁵N stable isotope semen label to detect mating in the malaria mosquito Anopheles arabiensis Patton [PDF]

, 2008
In previous studies it was determined that the stable isotope 13-carbon can be used as a semen label to detect mating events in the malaria mosquito Anopheles arabiensis. In this paper we describe the use of an additional stable isotope, 15-nitrogen (15N)

Mitochondrial Protection and Neural Repair via ROS‐Responsive Biomimetic Nanoparticles in Intracerebral Hemorrhage

Advanced Science, EarlyView.
A ROS‐responsive biomimetic nanoparticle platform co‐delivers DIDS and Mdivi‐1 to protect mitochondria and promote neural repair after intracerebral hemorrhage. By targeting LPAR1/VDAC1‐related mitochondrial dysfunction, the nanotherapy reduces oxidative injury, neuronal apoptosis, and blood‐brain barrier disruption, improving neurological recovery and

Toward improved drought tolerance in bioenergy crops: QTL for carbon isotope composition and stomatal conductance in Populus

, 2013
Dedicated non-food bioenergy crops like poplar are needed as sustainable, low-input feedstocks for renewable energy in a future drier climate, where they can be grown on marginal soils. Such plants should have a low water, carbon, and chemical footprint.

Phosphine Coordination to Ce, Nd, Np, and Pu in ArBiAMPtBu‐Supported Complexes and Their 2H and 13C Isotopologues

Advanced Science, EarlyView.
A dianionic ligand designed to encourage metal‐phosphine coordination—bis((3,5‐dimethylphenyl)amidomethyl)tertbutylphosphine (ArBiAMPtBu)—was employed in the synthesis of paramagnetic complexes of Ce, Nd, Np, and Pu, producing MI(ArBiAMPtBu)(thf)3.

Epithelial SLC25A20 Deficiency Drives Immunosuppressive Neutrophil Remodeling via ARG1 Palmitoylation to Promote Colorectal Cancer

Advanced Science, EarlyView.
SLC25A20 deficiency in tumor cells compromises mitochondrial LCFA transport, which suppresses FAO and drives compensatory release of palmitic acid‐enriched lipids into the TME. These tumor‐derived palmitic acids are taken up by TANs, promoting ZDHHC18‐catalyzed ARG1 palmitoylation.

Lactate Signal: Modulator of Cellular Energy Production and Anabolism

Advanced Science, EarlyView.
Compartmentalized lactate signaling provides a spatial framework for understanding how lactate‐rich states are generated, transported, sensed, and translated into biological outputs. This Review integrates extracellular, cytosolic, mitochondrial‐associated, and nuclear lactate mechanisms to explain how lactate shapes metabolic adaptation, immune ...

Method for Analyzing the Molecular and Carbon Isotope Composition of Volatile Hydrocarbons (C1–C9) in Natural Gas

Journal of Analytical Methods in Chemistry, 2018
Solid-phase microextraction (SPME) coupled with gas chromatography-isotope ratio mass spectrometry (GC-IRMS) has already been applied to collect and identify volatile light hydrocarbons in oil and source rocks.

Oral Actinomyces Species Exposure is Associated with Anxiety‐Like Behavior, Mitochondrial Remodeling, and Altered GABAergic Pathways

Advanced Science, EarlyView.
Oral exposure to cannabis‐associated Actinomyces species, particularly A. meyeri, is associated with anxiety‐like behavior in mice in the absence of detectable bacterial translocation or overt systemic inflammation. These findings support a potential oral‐brain metabolic axis involving candidate metabolites such as arginine and argininosuccinate ...
