The application of multifunctional materials in various fields such as electronics and signal processors has attracted massive attention. Herein, a new organic-inorganic hybrid material [Et_(3)NCH_(2)Cl]_(2)[MnBr_(4)](1) is reported, which contains two organic amines cations and one [MnBr_(4)] tetrahedral ion. Compound 1 has a dielectric anomaly signal at 338 K, which proves its thermodynamic phase transition. The single crystal measurements at 200 K and 380 K show that the phase transition of compound 1 is caused by the thermal vibration of organic amine cations in the lattice. Moreover, compound 1 shows yellow-green luminescence under UV light irradiation. The magnetism measurements indicate that compound 1 shows switchable magnetic properties. This organic–inorganic material is a multifunctional material with dielectric, optical, and magnetic synergetic switchable effects, which expands a new direction for designing multifunctional materials.

Black wolfberry (Lycium ruthenicum) is enriched in phytochemical metabolites which can benefit human health. However， few studies have examined the effects of different fruit drying methods on its polyphenol content， antioxidant activity， and anti-inflammatory activity. In addition， whether and how consuming dried black wolfberry affects gut microbiota has not been reported. Here， we assessed the phytochemical profile and bioactivities of black wolfberry dried through different methods， and subsequently characterized changes in human fecal microbiota associated with freeze-dried black wolfberry in vitro. The results showed that freeze-dried samples retained higher total polyphenols (49.68 ± 1.62) mg GAE/g， tannins (38.64 ± 1.35) mg GAE/g， and proanthocyanidins (3.35 ± 0.30) mg/g compared to sun drying or hot air drying (P < 0.05)， and exhibited higher antioxidant and anti-inflammatory activities. In bioreactor fermentations of human fecal inoculum， freeze-dried black wolfberry was associated with increased species richness and alpha diversity. At the genus level， fermentations treated with black wolfberry had higher abundance of Lactic Acid Bacteria including Lactococcus， Bifidobacterium， Lactobacillus， Pediococcus and Weissella， as well as butyrate-producing bacteria compared to the untreated samples， suggesting enrichment for taxa associated with a healthy gut microbiome. In addition， the black wolfberry treatment group had higher levels of short-chain fatty acids， which was consistent with PICRUSt2 inference. This study defines an optimal method for black wolfberry preservation to retain the beneficial compounds， and provides a foundation for further exploration of its potential benefits for human gut microbiota.

该研究利用Caco-2细胞和正常大鼠考察大麻二酚(cannabidiol,CBD)体外吸收特性和体内药代动力学特征,并进一步研究其抗炎机制。通过CCK-8法确定CBD安全浓度范围,研究时间、浓度、温度、内吞抑制剂和转运抑制剂对CBD跨膜吸收和转运的影响;检测大鼠灌胃给药后不同时间的血药浓度,绘制药-时曲线,计算药代动力学参数;脂多糖(LPS)诱导Caco-2细胞建立炎症损伤模型,检测CBD干预处理后乳酸脱氢酶(LDH)活力、跨膜电阻(TEER)值以及细胞炎症因子水平探究CBD抗炎作用机制。结果表明在实验浓度范围内,Caco-2细胞对CBD的摄取在2 h达到饱和,CBD摄取量和浓度、温度呈正相关,可被内吞进入细胞。CBD可以通过多药耐药蛋白2(MRP2)和乳腺癌耐药蛋白(BCRP)参与的主动转运途径穿透Caco-2细胞,而加入P-gp抑制剂对CBD的转运没有影响。大鼠对CBD吸收迅速,达峰时间tmax为(1.00±0.11)h,在体内的消除较快,t1/2仅为(1.86±0.16)h。另外,CBD显著改善了炎症反应带来的LDH活力升高和TEER降低的现象,可通过降低促炎细胞因子白细胞介素-8(IL-8)、白细胞介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)的表达维持肠道屏障,起到抗炎作用。

尺寸小于2 nm的手性胶体半导体魔尺寸团簇(MSCs)为手性配体提供了丰富的表面结合位点,因此在手性半导体纳米材料应用方面具有巨大潜力.然而,手性MSCs的制备和光学表征却鲜有报道.本研究以手性半胱氨酸为配体,首次在室温水溶液中合成了单组合形式的手性MSCs,其中CdS MSCs在366 nm波长处有独特的尖锐吸收峰,CdSe MSCs在420 nm波长处有独特的尖锐吸收峰.通过改变手性配体的添加量,可以很容易地调节所制备的手性MSCs的光学活性.制备的手性CdS MSCs和CdSe MSCs的最大吸收不对称系数分别达到3.6×10^(−4)和5.6×10^(−4).实验结果表明,制备的MSCs的手性光学特性可能来源于配体诱导MSCs表面的原子重排.本研究不仅提供了制备手性MSCs的方法,而且为手性MSCs的研究和应用开辟了道路.
