Block Electrochemiluminescence of Luminol through O-Etherification and Its Application in Sensing of β-Glucosidase.

Luminol is a well-known electrochemiluminescence (ECL) fluorophore that is applied in various sensing fields as an ECL reporter. Regulating the signal off/on transition of an ECL fluorophore offers great opportunities for sensors' design; however, such attempts on luminol are extremely scarce as it was regarded to lack promising modification sites. In this study, we developed four luminol derivatives with modification at the amine site and the enol site and systematically explored possible caging strategies to regulate ECL emission.

The correlation between immune cells and endometriosis: a bidirectional two-sample mendelian randomization study.

Objectives: Endometriosis (EM), a prevalent estrogen-dependent inflammatory disorder affecting women of reproductive age, is characterized by the presence of endometrial-like tissue outside the uterus, resulting in pelvic scarring, pain, and infertility. Although the pathogenesis of EM remains poorly understood, there is growing evidence suggesting the involvement of the immune system in its etiology, pathophysiology, and associated morbidities such as pain, infertility, and adverse pregnancy outcomes. While previous studies have indicated a close relationship between the immune system and EM, the specific underlying mechanism remains incompletely elucidated.

Enhanced photocatalytic performance and a mechanistic study of novel black phosphorus/graphene/TiO composite membrane for o-chlorophenol removal.

The heterogeneous catalysis of the composite membrane not only exerts the synergistic effect of different materials but also enable the recyclable use of catalysts, making it an ideal and sustainable strategy for removing pollutants in water.

Different effects of low- and high-density lipoproteins in egg yolk on lipid metabolism of mouse: Role of phospholipids-to-cholesterol intake ratio.

Recent evidence increasingly indicates that moderate egg consumption (up to one egg per day) poses no significant risk of cardiovascular diseases in healthy individuals, leading researchers to speculate whether other lipids in eggs affect lipid metabolism. In this research, C57BL/6J mice were given chow diets containing egg yolk low-density lipoprotein (LDL) and high-density lipoprotein (HDL), two natural components with different proportions of phospholipids and cholesterol, to explore the effects of the phospholipids-to-cholesterol intake ratio on lipid metabolism. Increases in liver weight and liver index were observed following LDL intake, while body weight and epididymal fat decreased after HDL intake in a dose-dependent manner.

Leveraging logistic models to enhance nutrient dynamics modeling in intercropped spring wheat with varied nitrogen and phosphorus fertilization strategies.

Intercropping systems offer substantial benefits in crop yield nd nutrient absorption. Utilizing logistic models, we simulated the dynamic of nutrient uptake and accumulation in spring wheat and the impact of different planting patterns and compound fertilizer application rates on spring wheat yield. We conducted a field experiment involving two planting patterns: spring wheat monoculture (MS) and spring wheat-pea intercropping (MI), with five compound fertilizer applications: C0 (0 kg ha-1), C1 (480 kg ha-1), C2 (540 kg ha-1), C3 (600 kg ha-1), and C4 (660 kg ha-1).

Ultrasensitive SERS Profiling of Intracellular Hydrogen Peroxide Release Based on Enzymatic Amplification and Silent-Region Raman Reporter.

Surface-enhanced Raman scattering spectroscopy (SERS) has been widely applied to screen biomarkers and biological species due to its high sensitivity; however, severe background noise signals significantly limit its practical application. In this study, we develop an ultrasensitive SERS sensor to determine cellular oxidative stress based on the HO-induced enzymatic amplification and a silent-range Raman fingerprint. In the presence of horseradish peroxidase, HO could trigger the coupling reaction of 4-hydroxythiophenol (4-MTP) with phenol-d5 to form a new compound, which can bind to the SERS substrate via the Au-S bond and generate the stable SERS signal with nearly zero background signals owing to the Raman-silent fingerprint of phenol-d5 at 2125 cm.

Transcriptomic era of cancers in females: new epigenetic perspectives and therapeutic prospects.

In the era of transcriptomics, the role of epigenetics in the study of cancers in females has gained increasing recognition. This article explores the impact of epigenetic modifications, such as DNA methylation, histone modification, and non-coding RNA, on cancers in females, including breast, cervical, and ovarian cancers (1). Our findings suggest that these epigenetic markers not only influence tumor onset, progression, and metastasis but also present novel targets for therapeutic intervention.
