Hypoxia and Sturgeons: report to the Chesapeake Bay Program Dissolved Oxygen Criteria Team [PDF]

open access: yes, 2001
In this essay, three lines of evidence are developed that sturgeons in the Chesapeake Bay and elsewhere are unusually sensitive to hypoxic conditions: 1.

Ultra‐Fine 3D Bioprinting of Dynamic Hyaluronic Acid Hydrogel for in Vitro Modeling

open access: yesAdvanced Materials, EarlyView.
3D bioprinting merges tissue engineering and additive manufacturing to create biological structures. A bioink is developed by modifying hyaluronic acid, a natural extracellular matrix polymer, with cysteine. Potassium iodide is later added to tune gelation kinetics, enabling fine printing with a 32G needle.

Thermal tolerance in an extremophile fish from Mexico is not affected by environmental hypoxia

open access: yesBiology Open
ABSTRACT The thermal ecology of ectotherm animals has gained considerable attention in the face of human-induced climate change. Particularly in aquatic species, the experimental assessment of critical thermal limits (CTmin and CTmax) may help to predict possible effects of global warming on habitat suitability and ultimately species ...

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance

open access: yesAdvanced Materials, EarlyView.
This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.

3D Printed Magnetic Origami Scaffolds for Guided Tissue Assembly

open access: yesAdvanced Materials Interfaces, EarlyView.
3D‐printed magnetic origami scaffolds enhance 3D coculture by directing cell proliferation pre‐folding, restricting expansion for controlled growth within the channel, and spatially and temporally promoting 3D multicellular dissemination post‐folding.

The use of the ethanol pathway in goldfish Carassius auratus (L.) following anoxia [PDF]

open access: yes, 2001
Goldfish (Carassius auratus) were subjected, for a period of 6 weeks, to 2h progressive hypoxia followed by 6h anoxia in closed respirometers at 15 degree C.

Progress and Application of Multifunctional Hydrogel in Radioactive Skin Injury

open access: yesAdvanced Materials Interfaces, EarlyView.
This review examines healing challenges in radiation‐wound injuries, where ionizing radiation impairs immune and tissue repair processes. Hydrogels, with their biocompatibility, antimicrobial properties, and drug delivery capabilities, present a transformative solution. It compares hydrogel efficacy in radiation‐induced versus common wounds, highlights

Red Blood Cell Membrane‐Camouflaged Red Phosphorus‐Modified C3N4 for Enhanced Tumoral Photodynamic Therapy

open access: yesAdvanced Materials Interfaces, EarlyView.
Photodynamic therapy (PDT) faces clinical challenges due to poor tumor targeting and systemic toxicity. Herein, a biomimetic C3N4‐RP@RBCm nanoplatform is developed via erythrocyte membrane encapsulation, enabling CD47‐mediated immune evasion and EPR‐driven tumor accumulation.

Oral application of L-menthol in the heat: From pleasure to performance [PDF]

open access: yes, 2019
When menthol is applied to the oral cavity it presents with a familiar refreshing sensation and cooling mint flavour. This may be deemed hedonic in some individuals, but may cause irritation in others.
