Polydopamine Nanodots Ameliorate Inflammatory Bowel Disease by Restoring Redox Homeostasis and Intestinal Microenvironment

Advanced Science, EarlyView.
A novel melanin‐based therapeutic composed of ultrasmall polydopamine nanodots is employed as an efficient oral formulation for the targeted treatment of inflammatory bowel disease. The potential therapeutic mechanism of polydopamine nanodots mainly involves the elimination of excessive oxidative stress, the reduction of ROS‐mediated proinflammatory ...

Geometrically Encoded Positioning of Introns, Intergenic Segments, and Exons in the Human Genome

Advanced Science, EarlyView.
This study introduces a new hypothesis: exons, introns, and intergenic segments are non‐random projections of the functional layers of 3D structure of chromatin packing domains. Evidence is presented that this “geometric code” may encode volumetric structure, reconciling epigenetic patterns, correlates with oncogenic mutations, acting as a potential ...

Evaluation of polymerization shrinkage stress and cuspal strain in natural and typodont teeth [PDF]

Brazilian Oral Research
To evaluate the polymerization shrinkage stress and cuspal strain (CS) generated in an artificial (typodont) and in a natural tooth using different resin composites. Twenty artificial and 20 extracted natural molars were selected. Each tooth was prepared

T1WI‐SWI Dual Modal Magnetic Resonance Nanoprobes for Accurate Diagnosis of Early Stage Alzheimer's Disease

Advanced Science, EarlyView.
We developed a smart MRI nanoprobe targeting BACE1 and Aβ plaques. It crosses the blood‐brain barrier. Upon encountering BACE1, the probe is cleaved, enabling T1WI imaging detection. Subsequent reaction with ONOO− induces probe aggregation, enhancing magnetic susceptibility for sensitive SWI imaging of Aβ plaques.

Hydroxyapatite promotes superior adhesion and proliferation of telomerase transformed keratocytes in comparison with inert plastic skirt materials used in leading contemporary keratoprostheses [PDF]

, 2005
Aim: Published clinical series suggest the osteoodontokeratoprosthesis (OOKP) may have a lower extrusion rate than current synthetic keratoprostheses. The OOKP is anchored in the eye wall by autologous tooth.
