LIPUS Promotes Calcium Oscillation and Enhances Calcium Dependent Autophagy of Chondrocytes to Alleviate Osteoarthritis

Advanced Science, EarlyView.
A non‐invasive and safe physical therapy, low‐intensity pulsed ultrasound (LIPUS) can alleviate osteoarthritis. This study dynamically “visualizes” the invisible mechanical stimuli of LIPUS on living chondrocytes by fluorescence imaging technology in the form of calcium oscillations, confirming LIPUS maintains cartilage homeostasis by promoting ...

Mannose‐Glycated Metal‐Phenolic Microcapsules Orchestrate Phenotype Switch of Macrophages for Boosting Tumor Immunotherapy

Advanced Science, EarlyView.
Immunomodulatory metal‐phenolic microcapsules (mMPMs) is developed in this study that leverages dopamine‐modified hyaluronic acid and FeIII assemble on mannose‐glycated bovine serum albumin microbubbles. mMPMs effectively promote macrophage internalization and M1 polarization, enhancing pro‐inflammatory responses.

The grease trap: uncovering the mechanism of the hydrophobic lid in Cutibacterium acnes lipase[S]

Journal of Lipid Research, 2020
Acne is one of the most common dermatological conditions, but the details of its pathology are unclear, and current management regimens often have adverse effects. Cutibacterium acnes is known as a major acne-associated bacterium that derives energy from

Development of a Three-Dimensional Multiscale Agent-Based Tumor Model: Simulating Gene-Protein Interaction Profiles, Cell Phenotypes & Multicellular Patterns in Brain Cancer [PDF]

arXiv, 2006
Experimental evidence suggests that epidermal growth factor receptor (EGFR)-mediated activation of the signaling protein phospholipase C gamma plays a critical role in a cancer cell's phenotypic decision to either proliferate or to migrate at a given point in time. Here, we present a novel three-dimensional multiscale agent-based model to simulate this

Photometric Determination of Phospholipase A [PDF]

Clinical Chemistry and Laboratory Medicine, 1986
A photometric method for the determination of phospholipase A is described, in which fatty acids are liberated from phosphatidylcholine and measured by a discontinuous enzymatic test. Optimal test conditions were evaluated using purified phospholipase A from human and porcine pancreas.

A neurotoxic phospholipase A2 impairs yeast amphiphysin activity and reduces endocytosis. [PDF]

PLoS ONE, 2012
BACKGROUND: Presynaptically neurotoxic phospholipases A(2) inhibit synaptic vesicle recycling through endocytosis. PRINCIPAL FINDINGS: Here we provide insight into the action of a presynaptically neurotoxic phospholipase A(2) ammodytoxin A (AtxA) on ...

Mapping Complex Networks: Exploring Boolean Modeling of Signal Transduction Pathways [PDF]

arXiv, 2009
In this study, we explored the utility of a descriptive and predictive bionetwork model for phospholipase C-coupled calcium signaling pathways, built with non-kinetic experimental information. Boolean models generated from these data yield oscillatory activity patterns for both the endoplasmic reticulum resident inositol-1,4,5-trisphosphate receptor ...
