Characterization of Bone Structure in Leptin Receptor-Deficient Zucker (fa/fa) Rats

Journal of Bone and Mineral Research, 2003
Abstract To investigate the role of leptin in bone formation, the skeleton of the obese female leptin receptor-deficient Zucker rat was examined using pQCT, μCT, and histomorphometry. A trend toward decreasing structural and bone formation parameters in these rats as they age suggest that leptin has a small positive effect on bone.

Oral Delivery Systems for Food‐Derived Bioactive Peptides: Enhancing Stability, Bioavailability, and Health Benefits

Advanced Science, EarlyView.
Advanced delivery systems—including nanoparticles, nanoemulsions, liposomes, and hydrogels—protect food‐derived bioactive peptides from gastrointestinal degradation and bitterness. These systems enable pH‐responsive release, enhance intestinal absorption, and improve therapeutic efficacy against oxidative stress, metabolic disorders, cancer, and ...

Avicin D, a plant triterpenoid, induces cell apoptosis by recruitment of Fas and downstream signaling molecules into lipid rafts. [PDF]

PLoS ONE, 2009
Avicins, a family of triterpene electrophiles originally identified as potent inhibitors of tumor cell growth, have been shown to be pleiotropic compounds that also possess antioxidant, anti-mutagenic, and anti-inflammatory activities.

Fas death receptor signalling: roles of Bid and XIAP [PDF]

Cell Death & Differentiation, 2011
Fas (also called CD95 or APO-1), a member of a subgroup of the tumour necrosis factor receptor superfamily that contain an intracellular death domain, can initiate apoptosis signalling and has a critical role in the regulation of the immune system. Fas-induced apoptosis requires recruitment and activation of the initiator caspase, caspase-8 (in humans ...

Engineering‐Modulated Molybdenum Enzymes Strategy for Tumor‐Specific Metabolic‐Immunotherapy

Advanced Science, EarlyView.
Biodegradable molybdenum sulfide nanoparticles were synthesized via a one‐pot strategy to increase molybdenum enzyme activity and thus effectively potentiate anti‐tumor immunity by integrating molybdenum‐based metalloimmunotherapy with hydrogen sulfide gas therapy.

Anti-Fas mAb-induced apoptosis and cytolysis of airway tissue eosinophils aggravates rather than resolves established inflammation

Respiratory Research, 2005
Background Fas receptor-mediated eosinophil apoptosis is currently forwarded as a mechanism resolving asthma-like inflammation. This view is based on observations in vitro and in airway lumen with unknown translatability to airway tissues in vivo.

Normal levels of serum corticosterone and hepatic glucocorticoid receptors in obese (fa/fa) rats

Bioscience Reports, 1987
In an attempt to understand the hyper-responsiveness to glucocorticoids that is characteristic of genetically obese fa/fa rats, we have measured the levels of free corticosterone in serum from lean and obese rats as well as the number of “cytosolic” and “nuclear” binding sites in livers of these rats. Both the lean and obese rats had similar amounts of

Hypothalamic Control of Liver Health and Disease: From Circuits to Pathophysiology and Therapies

Advanced Science, EarlyView.
This review delineates the hypothalamic circuits that control liver homeostasis via autonomic and neuroendocrine pathways. Dysregulation of this hypothalamus–liver axis drives disease progression across a spectrum including steatotic liver disease, liver inflammation and injury, fibrosis, cirrhosis, and hepatocellular carcinoma.

Fas induces apoptosis in human coronary artery endothelial cells in vitro

BMC Cell Biology, 2004
Background Published work suggests that some types of endothelial cells undergo apoptosis in response to ligation of the receptor Fas (CD95, APO1) but other types are resistant.

Machine Learning‐Assisted Design and Performance Prediction of a Compact Dual‐Band Polarization‐Insensitive THz Metamaterial Absorber for Skin‐Cancer‐Related Refractive‐Index Sensing

Advanced Electronic Materials, EarlyView.
A compact QASRR‐based THz metamaterial absorber enables polarization‐insensitive dual‐band absorption and skin‐cancer‐related refractive‐index sensing through measurable resonance shifts. Field, surface‐current, and circuit analyses clarify the dual‐resonance mechanism, while StackNet‐assisted prediction accurately estimates the simulated absorption ...
