Solvent-Free Artificial Light-Harvesting System in a Fluid Donor with Highly Efficient Förster Resonance Energy Transfer.

Multi-step Förster resonance energy transfer (FRET) plays a vital role in photosynthesis. While the energy transfer efficiency (Φ) of a naturally occurring system can reach 95%, that of most artificial light-harvesting systems (ALHSs) is still limited. Herein, we propose a strategy to construct highly efficient ALHSs using a blue-emitting, supercooled ionic compound of naphthalimide (NPI) as the donor, a green-emitting BODIPY derivate as a relay acceptor, and a commercially available, red-emitting dye [rhodamine B (RhB)] as the final acceptor.

Essential oils from Amorpha fruticosa against hepatocellular carcinoma based on network pharmacology.

Background: Amorpha fruticosa was used for treating burn, ambustion, carbuncle, and eczema in the traditional Chinese medicine. Although more and more attention has been paid to its biological activity recently, the antitumor activities of the essential oils (EOs) extracted from its leaves (AFLEO) and flowers (AFFEO), and their molecular mechanisms have never been reported up to now. The objective of present study was to examine the chemical compositions of AFLEO and AFFEO, then investigate the effects and pharmacological mechanism of EOs against hepatocellular carcinoma (HCC).

Diabetes Mellitus Impairs Blood-Brain Barrier Integrality and Microglial Reactivity.

Diabetes mellitus (DM), a chronic metabolic disorder that adversely affects the blood-brain barrier (BBB) and microglial function in the central nervous system (CNS), contributing to neuronal damage and neurodegenerative diseases. However, the underlying molecular mechanisms linking diabetes to BBB dysfunction and microglial dysregulation remain poorly understood. Here, we assessed the impacts of diabetes on BBB and microglial reactivity and investigated its mechanisms.

Efficacy of 4-dimensional hysterosalpingo-contrast sonography and X-ray hysterosalpingography in infertility.

Objective: To assess and compare efficacy of 4-dimensional hysterosalpingo-contrast sonography (4D-HyCoSy) and X-ray hysterosalpingography (HSG) for fallopian tube examination.

Methods: Clinical data of patients with suspected tubal infertility, who underwent examinations in Qingdao Women and Children's Hospital from September 2021 to December 2023, were retrospectively analyzed. Of them, 40 patients received laparoscopy and dye test+ 4D-HyCoSy (4D-HyCoSy group), and 36 patients received laparoscopy and dye test +HSG (HSG group).

Pretreatment HIV Drug Resistance to Integrase Strand Transfer Inhibitors Among Newly Diagnosed HIV Individuals - China, 2018-2023.

Introduction: The widespread adoption of integrase strand transfer inhibitors (INSTIs) has led to the emergence of INSTI-associated drug-resistance mutations. This cross-sectional study conducted a comprehensive national survey to investigate the prevalence of pretreatment drug resistance (PDR) to INSTIs among newly diagnosed human immunodeficiency virus (HIV) individuals in China.

Methods: The study enrolled 10,654 individuals from 31 provincial-level administrative divisions between 2018 and 2023.
