Effect of different extraction methods on the lipid composition and antioxidant activity of Ziziphi spinosae semens oil.

Chinese sour jujube is an important fruit for both medicine and food and effects various biological activities. Although the Chinese sour jujube seed (Ziziphi spinosae semen) is rich in oil, its lipid profiles is significantly affected by the extraction process. However, no studies to date have comprehensively analysed the lipid composition and bioactivity of Ziziphi spinosae semen oil processed using different methods.

Wuling capsule modulates macrophage polarization by inhibiting the TLR4-NF-κB signaling pathway to relieve liver fibrosis.

Background And Purpose: Wuling capsule (WL) has good efficacy in the clinical treatment of chronic hepatitis B and liver injury. Liver fibrosis is a common pathological feature of chronic liver disease and may progress to irreversible cirrhosis and liver cancer. Accumulating evidence reveals that modulating macrophage polarization contribute to the therapy of liver fibrosis.

Synthesis and Thermoreversible Gelation of Coil-Rod Copolymers with a Dendritic Polyethylene Core and Multiple Helical Poly(γ-benzyl-L-glutamate) Arms.

Coil-rod copolymers with a dendritic polyethylene (DPE) core and multiple helical poly(γ-benzyl-L-glutamate) (PBLG) arms (DPE-(PBLG)) were prepared by palladium-catalyzed copolymerization in tandem with ring-opening polymerization (ROP). Macroinitiator (DPE-(NH)) was firstly prepared by the group transformation of DPE-(OH) generated from palladium-catalyzed copolymerization of ethylene and acrylate comonomer. Coil-helical DPE-(PBLG) copolymers were prepared by ROP of γ-benzyl-L-glutamate-N-carboxyanhydride (BLG-NCA).

Radix Angelica dahuricae extract ameliorates oestrogen deficiency-induced dyslipidaemia in ovariectomized (OVX) rats by modulating the gut microbiota and bile acid signalling.

Background: Radix Angelica dahuricae (RAD), a well-known traditional Chinese medicine, displays a promising effect on alleviating lipid metabolism. However, the improvement of RAD on oestrogen deficiency-induced dyslipidaemia and the underlying mechanism are unclear.

Purpose: The aim of this study was to study the effect of RAD on oestrogen deficiency-induced dyslipidaemia in ovariectomized (OVX) rats and investigate the involvement of the gut microbiota and bile acid signalling in the protective effects.

L. Regulates Glutathione Redox Stress and Normalizes Ggt1/Anpep Signaling to Alleviate OVX-Induced Kidney Dysfunction.

Menopause and associated renal complications are linked to systemic redox stress, and the causal factors remain unclear. As the role of L. (HPL) in menopause-induced kidney disease therapy is still ambiguous, we aim to explore the effects of HPL on systemic redox stress under ovariectomy (OVX)-induced kidney dysfunction conditions.

Improvements in estrogen deficiency-induced hypercholesterolemia by Hypericum perforatum L. extract are associated with gut microbiota and related metabolites in ovariectomized (OVX) rats.

Hypericum perforatum L. (HP), a well-known natural medicine, has a potential effect on menopausal hypercholesterolemia. However, the effect of HP extract on gut microbiota and related metabolites, which play vital roles in metabolic disease occurrence, in the context of estrogen deficiency have not yet been reported.

ER-depletion lowering the 'hypothalamus-uterus-kidney' axis functions by perturbing the renal ERβ/Ptgds signalling pathway.

Researchers have long assumed that systematic estrogen fading might contribute to the sustained progression of menopausal degenerate syndromes, although definitive evidence has not been presented. Whether such findings represent a causal contribution or are the result of opportunistic messengers sent from the reproductive system to the brain is also a vital question. We constructed a multiscale network of the ovariectomy (OVX) induced estrogen receptors depletion (ER-depletion) model and integrated targeted proteomic, targeted lipidomic, cytochemical, and histopathological data across three tissues from the ovariectomy rodent model.

[Quantitative determination of nine furanocoumarins for quality evaluation of Angelica dahurica from different habitats].

A UPLC method has been developed for simultaneous determination of nine furanocoumarins of Angelica dahurics,and was used for quality evaluation of A. dahurica from different habitats. ACQUITY UPLC BEH C18 chromatographic column was employed,the separation was performed with the mobile phase consisting of acetonitrile and water,and the detection wavelength was set at254 nm.

[Effects of shading on key enzyme genesexpression and accumulation of saponins in Panax japonicus var. major].

To explore the effects of shading and the expression of key enzyme genes on the synthesis and accumulation of Panax japonicus var. major saponins, different shading treatments (0%, 30%,50%) of potted P. japonicus var.

Fabrication of Positively Charged Fluorescent Polymer Nanoparticles for Cell Imaging and Gene Delivery.

Development of efficient non-viral gene delivery vector has aroused great attention in the past few decades. In this study, we reported a new gene delivery vector, positively charged fluorescent conjugated polymer nanoparticles (CPNPs), for efficient gene transfection and in-situ intracellular fluorescence imaging. The microscopic and spectroscopic characterizations demonstrated that these CPNPs possess decent fluorescence performance (e.

To explore the flavor and meridian tropism classification of Callianthemum taipaicum by principal components analysis(PCA) and partial least square analysis(PLS). Meanwhile,to establish a high performance liquid chromatography-tandem mass spectrometry(HPLC-ESI-MS) method for the simultaneous determination of 55 active components from 13 kinds of Ranunculaceae of Chinese traditional herbs. Samples were separated on HPLC system by Agilent 5 TC-C₁₈（2）（4.

Synthesis of hyperbranched polyethylene amphiphiles by chain walking polymerization in tandem with RAFT polymerization and supramolecular self-assembly vesicles.

A novel polymerization methodology for efficient synthesis of hyperbranched polyethylene amphiphiles by chain walking polymerization (CWP) followed by RAFT polymerization has been developed. Hyperbranched polyethylene with hydroxyl ends (HBPE-OHs) is first synthesized via chain walking copolymerization of ethylene with 2-hydroxyethyl acrylate with Pd-α-diimine catalyst. The hydroxyl groups of hyperbranched polyethylene are then converted into thiocarbonyl thio moieties by an esterification reaction with trithiocarbonate 3-benzylsulfanylthiocarbonyl sulfanylpropionic acid (BSPA).
