Heterole-Fused [20]- and [22]Smaragdyrins and Fused-Heterole-Bridged [20]- and [22]Smaragdyrin Dimers.

In order to examine the effects of the fused heterole on the electronic properties of aromatic and antiaromatic smaragdyrins, 2,3-thiophene- and 2,3-indole-fused [20]smaragdyrins were synthesized by Suzuki-Miyaura coupling and subsequent oxidative fusion reaction, and were reduced with NaBH4 to the corresponding [22]smaragdyrins. Fused-thiophene- and fused-pyrrole-bridged [20]- and [22]smaragdyrin dimers were also synthesized in the similar manner. The installed fused heteroles mitigate the paratropic ring current of the [20]smaragdyrin but exert only minor effects on the diatropic ring current of the [22]smaragdyrin.

Construction of Self-Cleaning Membrane Integrating Underwater Superoleophobicity, Photocatalysis, and Antibacterial Activity for Water Purification.

The treatment of oily wastewater and oil/water mixtures has received more and more attention. In this study, a Zn-MOF (ZIF-8) decorated polyimide (PI) nanofiber membrane with triple self-cleaning performance was constructed, and the decoration of ZIF-8 on the PI membrane improved the hydrophilicity of the composite membrane, which further enhanced the underwater oil resistance, and the mechanical properties of the membranes improved significantly with the increase of in situ growth time. In addition, the inherent photocatalytic and antibacterial properties of ZIF-8 endowed the membranes with fantastic performance.

The influence of different geographical origins and grades on the flavor of Qingxiangxing Baijiu: An integrated analysis using descriptive sensory evaluation, GC×GC-MS, E-nose, and ICP-MS.

The origin and grade are the important factors that influence the flavor and price of Qingxiangxing Baijiu (QXB). As the grade increased, sensory differences and geographical differences become more pronounced. The aromas of floral, fruity, and sweet become more noticeable, while the acidity decreased.

Injectable, Biodegradable and Photothermal Hydrogel with Quorum Sensing Inhibitory Effects for Subcutaneous Fungal Infection Treatment.

Owing to the high invasion depth and easy formation of biofilms, the treatment of subcutaneous fungal infection is intractable and challenging. Herein, we report an injectable and biodegradable hydrogel with bactericidal, quorum sensing inhibition and antioxidant activities for the in situ treatment of subcutaneous fungal infection. The hydrogel (BEPE) was constructed by irradiating mixed bovine serum albumin (BSA), ε-polylysine and epigallocatechin gallate (EGCG)-loaded mesoporous polydopamine (PDA) under near-infrared (NIR) light.

Conventional and genetic association between migraine and stroke with druggable genome-wide Mendelian randomization.

The genetic relationship between migraine and stroke remains underexplored, particularly in the context of druggable targets. Previous studies have been limited by small sample sizes and a lack of focus on genetic-targeted therapies for these conditions. We analyzed the association and causality between migraine and stroke using multivariable logistic regression in the UK Biobank cohort and Mendelian randomization (MR) analyses based on genome-wide association study (GWAS) data.
