[Yougui Yin attenuates adipogenic differentiation of bone marrow mesenchymal stem cells by modulating PPARγ pathway to treat glucocorticoid-induced osteonecrosis].

This study aims to investigate the pharmacological effects and mechanisms of Yougui Yin in treating glucocorticoid-induced osteonecrosis. A rat model of glucocorticoid-associated osteonecrosis of the femoral head(GA-ONFH) was established by intramuscular injection of dexamethasone at 20 mg·kg~(-1) every other day for 8 weeks. Rats were randomly allocated into control, model, and low-and high-dose(1.

Simultaneous and instrument-free detection of quinine and crystal violet based on a dual-emissive Eu-functionalized metal-organic framework.

Simultaneous detection and quantification of multi-targets is a challenge using one single sensor in the complicated environment of real samples. Herein, we developed a dual-emissive sensor (EuUCHNA) that selectively and rapidly responds to crystal violet (CV) and quinine (QN), two commonly used anti-infective drugs for fungi, bacteria, and parasites, through distinct responsive modes. CV can effectively quench the blue and red fluorescent emission bands of EuUCHNA.

Miniaturized inertial sensor based on high-resolution dual atom interferometry.

Atom interferometry shows high sensitivity for inertial measurements in the laboratory, but it faces difficulties in field applications because of a trade-off between sensitivity and size. Therefore, there is an urgent need to develop a small sensor with high resolution for measuring acceleration and rotation in inertial navigation applications. Presented here is a miniaturized inertial sensor capable of measuring acceleration and rotation simultaneously based on high-resolution dual atom interferometers.

Time-averaged atomic volume spectrum: locating and identifying vacancies.

Vacancies, as well as their derivatives, usually play a crucial role in many essential properties of materials. However, they always behave erratically, especially under universal thermal vibration, and are therefore difficult to accurately locate. Until now, the lack of an accurate and flexible method for locating and identifying vacancies has hampered the development of relative fields.

Facile one-precursor and one-pot synthesis of Girard's reagent T-based carbon dots for bacteria-resistant and anti-biofilm applications.
