Elephant seal cells export iron and form lipid droplets to evade lipid peroxidation

This study identifies a unique mechanism in elephant seal cells that prevents lipid peroxidation through lipid droplet formation and iron export, rather than traditional antioxidant pathways.

Three-dimensional T1 mapping demonstrates the transfer of oxygen into cerebrospinal fluid during hyperoxia

This study uses 3D T1 mapping to show oxygen transfer into cerebrospinal fluid during hyperoxia, revealing regional differences in oxygen diffusion dynamics.

Vertical Sleeve Gastrectomy inhibits 11βHSD1 and subsequently reduces IL6 secretion in Mice and Humans: A Shared Anti-Inflammatory Mechanism

This study shows that vertical sleeve gastrectomy reduces 11βHSD1 and IL6 in mice and humans, linking glucocorticoid metabolism to improved glucose homeostasis and reduced inflammation.

Proteomic profiling of experimental acute alcohol intoxication reveals FGF21 as a specific ethanol-induced hormone

This study identifies FGF21 as a specific ethanol-induced hormone through proteomic profiling of acute alcohol intoxication in humans.

AN INTEGRATED HEART-ON-A-CHIP NAM RESOLVES DISTINCT CLINICAL PHENOTYPES OF MYOCARDIAL ISCHEMIA-REPERFUSION INJURY

This paper develops a heart-on-a-chip model to distinguish structural, biochemical, and contractile changes in myocardial ischemia-reperfusion injury, linking them to distinct clinical phenotypes.

Cardiac unloading via a transvalvular pump prevents arrhythmias following myocardial ischemia / reperfusion by preserving coronary microcirculation and cardiomyocyte nanostructure

This study shows that transvalvular unloading reduces arrhythmias after myocardial ischemia/reperfusion by preserving coronary microcirculation and cardiomyocyte nanostructure in a porcine model.

Human brown adipose tissue demonstrates substantial 18F-fluorocholine uptake at room temperature for phosphatidylcholine synthesis

This study shows that 18F-fluorocholine PET can detect human brown adipose tissue at room temperature by measuring phosphatidylcholine synthesis, without requiring cold exposure.

Unimanual fatigue increases muscle excitation and local metabolic activity in the resting contralateral forearm

This study shows that unimanual fatigue increases contralateral muscle excitation and local metabolic activity in the resting forearm during vascular occlusion.

Intermediate, rather than Isohydric or Anisohydric, Species were More Resilient to an Extreme Heatwave in a Common Garden in Sydney

The study evaluates resilience of urban tree and shrub species to an extreme heatwave using functional traits, finding that crown dieback better predicts thermal stress than survival.

The RNA m6A reader YTHDF2 depletion phenocopies high glucose induced-cellular stress response in diabetic kidney disease

This study shows that YTHDF2 depletion mimics high glucose-induced stress in diabetic kidney disease by altering RNA processing and increasing oxidative stress.

Genomic Profiling of Estrogen-Related Receptor Identifies Adult Adipocyte-Specific Targets in Drosophila

The paper identifies ERR-specific genomic targets in adult Drosophila adipocytes using NanoDam, revealing its role in regulating metabolic pathways.

The Cardiovascular Benefit of Menopause Hormone Treatment is Age-Dependent in Ldlr-/- Mice

This study shows that menopause hormone treatment (E2) reduces atherosclerosis in young mice but not older mice, due to age-related changes in inflammation and estrogen receptor signaling.

Severe feed restriction in a fish: is the positive effects of nucleotide supplementation on growth recovery explained by one-carbon metabolism?

This study investigates whether nucleotide supplementation improves growth recovery in starved charrs by examining one-carbon metabolism changes during refeeding.

Unconventional Small Molecule MNP-021 Protects Neuronal and Glial Function from Diabetes-Associated Glucotoxicity and Neuroinflammation

This paper tests the neuroprotective effects of MNP-021 against diabetes-induced glucotoxicity and neuroinflammation in neurons and glial cells, finding it restores glucose handling, mitochondrial function, and pro-resolving signaling.

The broccoli derivative sulforaphane extends lifespan by slowing the transcriptional aging clock

This study shows sulforaphane extends C. elegans lifespan by over 50% when administered early and reduces transcriptional age by 20%.

A Relaxin-Defined Late-Luteal Endocrine Transition State in the Human Menstrual Cycle

This study identifies relaxin-2 as a late-luteal hormone with a distinct peak in the menstrual cycle, showing precise timing and ovulation dependence.

A pump-leak model of epithelia reveals the roles of paracellular pathways in water transport & the importance of boundary conditions

The paper develops a pump-leak model of epithelial transport to show how paracellular pathways and boundary conditions influence water and ion fluxes, with a focus on electroneutrality and osmotic gradients.

Isocaloric restriction normalizes body weight but not relative adiposity, adipose inflammation, or gut microbial diversity in high-fat diet-fed mice

Dissecting the metabolic costs of up- and down-hill walking

The paper evaluates a musculoskeletal model to estimate muscle force- and work-related costs during uphill and downhill walking, finding they correlate with joint moments and net joint work, respectively.

A synchronization modulation electric field reduces early ischemic kidney injury in pigs and suppresses a stress and inflammatory program without detectable leukocyte accumulation
