Multi‐Responsive Dendrimer‐Hyaluronic Acid Hydrogel With Lubricating and Immunoregulatory Functions for Synergistic Osteoarthritis Therapy

Advanced Functional Materials, EarlyView.
A hydrogel with dynamic cross‐links was formed by cross‐linking hyaluronic acid with curcumin‐preloaded, phenylboronic acid‐modified poly(amidoamine) dendrimers. This hydrogel exhibited excellent injectability and self‐healing ability, enabling controlled Cur release in response to low pH, high reactive oxygen species (ROS) generation, or mechanical ...

TEST THE POTENTIAL OF PINEAPPLE (Ananas comosus L.) JUICE TO REDUCE CONTENT OF COPPER (Cu) METAL BY ATOMIC ABSORPTION SPECTROPHOTOMETRY (AAS)

Jurnal Farmasi Sains dan Praktis, 2021
Accumulation of copper (Cu) metal in the body causes tissue damage. Metals that can’t be excreted into the blood or bile by the liver can cause cirrhosis, so the body needs antidotes to reduce metal content.

HST Spectrophotometry and Models for Solar Analogs

, 2010
Absolute flux distributions for seven solar analog stars are measured from 0.3 to 2.5 \mu m by HST spectrophotometry.In order to predict the longer wavelength mid-IR fluxes that are required for JWST calibration, the HST SEDs are fit with Castelli ...

BGN/MDK Axis in the Melanoma Tumor Microenvironment Strengthens Tumor Malignancy by Modulating Cancer Cells and Cancer‐Associated Fibroblasts Crosstalk

Advanced Science, EarlyView.
This study reveals that m6A regulators cooperatively upregulate BGN in melanoma, promoting malignancy. Within the tumor microenvironment, CAFs show highest BGN expression. The BGN/MDK axis mediates cancer‐stroma crosstalk, driving normal fibroblast (NF) activation and enhancing the pro‐tumor effect of CAFs, highlighting a promising therapeutic target ...
