Variation of Hepatic Ethoxycoumarin O-de-ethylase Activity with Body Weight and Other Factors in Brook Trout (Salvelinus fontinalis)

open access: yes, 1982
Data from several previous experimental studies of hepatic mixed function oxidase (MFO) activity were reexamined to study the possible relationship between ethoxycoumarin O-de-ethylase activity and body weight and other factors in "uninduced" brook ...

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

open access: yesFEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Baeyer-Villiger monooxygenases : more than just green chemistry

open access: yes, 2011
What is life without oxygen is a rhetorical question. On the other hand, unraveling the intricacies and understanding the various mechanisms underpinning the biological processes beg many answers.

Safety of Prescription Nonsteroidal Anti‐inflammatory Drugs in Adults With Inflammatory Bowel Disease: Data From a Large Administrative Claims Cohort

open access: yesArthritis Care &Research, EarlyView.
Objective The concern that nonsteroidal anti‐inflammatory drugs (NSAIDs) may precipitate flares of inflammatory bowel disease (IBD) has limited their use in managing musculoskeletal symptoms in those with IBD, but safety data are mixed. Methods This retrospective cohort study included patients with IBD aged at least 18 years from Optum's deidentified ...

Covalent Inhibition of SHMT2 by Gambogic Acid Induces Ferroptosis Through Mitochondrial Collapse in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
In this study, chemoproteomics combined with genetic and functional analyses was integrated to identify SHMT2 as a covalent and functional target of gambogic acid (GA) in triple‐negative breast cancer (TNBC). Further validation demonstrated that GA selectively modifies the Cys241 site of SHMT2, triggering mitochondrial dysfunction, activating the Nrf2 ...

Porcine kidney xenotransplantation: From primate models to clinical reality

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

Chrysin alleviates pressure overload–induced myocardial remodeling through regulating the PI3K/AKT/NRF2 pathway–mediated oxidative stress response

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In this study, we primarily simulated pathological myocardial remodeling induced by transverse aortic constriction surgery and found significant cardiac hypertrophy and fibrosis, characterized by deteriorated cardiac function. Oxidative stress response is considered as a pivotal pathological process, which contributes to inflammation and apoptosis of ...
