[Optimal processing technology of Zhangbang vinegar-processed Olibanum with multi-indicator-response surface methodology and anticoagulant effect evaluation].

This study first optimized the processing technology for Zhangbang vinegar-processed Olibanum and investigated its in vitro anticoagulant activity. A multi-index-response surface methodology was used, with yield, powder yield, and the relative percentage of the content of six non-volatile components [11-keto-boswellic acid(KBA), 3-acetyl-11-keto-boswellic acid(AKBA), β-elemonic acid, α-boswellic acid(α-BA), β-boswellic acid(β-BA), and α-acetyl-boswellic acid(α-BA)] and three volatile components(octyl acetate, incensole, and incensole acetate) as evaluation indicators. Analytical hierarchy process(AHP) combined with coefficient of variation method was used to calculate the weight of each indicator and calculate the comprehensive score(OD).

[Mechanism of Euodiae Fructus stir-fried with water decoction of Coptidis Rhizoma in treatment of chronic colitis based on UPLC-Q-TOF-MS, network pharmacology and experimental verification].

To elucidate the mechanism of Euodiae Fructus stir-fried with water decoction of Coptidis Rhizoma in the treatment of chronic colitis, this study employed ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS), network pharmacology, and experimental verification to predict the involved targets and signaling pathways. The chronic colitis mouse model was constructed to verify the core targets. A total of 48 compounds in the herbal medicine were identified by UPLC-Q-TOF-MS.

Childhood Obesity and Risk of Stroke: A Mendelian Randomisation Analysis.

The causal relationship between childhood obesity and stroke remains unclear. Our objective was to elucidate the causal relationship between childhood obesity and the risk of stroke and its subtypes by performing Mendelian randomisation (MR) analyses. Genetic instruments for childhood obesity were obtained from a genome-wide association study (GWAS) of 13,848 European participants.

Niclosamide inhibits vascular smooth muscle cell proliferation and migration and attenuates neointimal hyperplasia in injured rat carotid arteries.

Background And Purpose: The anti-helminthic drug niclosamide regulates multiple cellular signals including STAT3, AMP-activated protein kinase (AMPK), Akt, Wnt/β-catenin and mitochondrial uncoupling which are involved in neointimal hyperplasia. Here we have examined the effects of niclosamide on vascular smooth muscle cell proliferation, migration and neointimal hyperplasia and assessed the potential mechanisms.

Experimental Approach: Cell migration was measured by using wound-induced migration assay and Boyden chamber assay.

Niclosamide ethanolamine inhibits artery constriction.

We previously demonstrated that the typical mitochondrial uncoupler carbonyl cyanide m-chlorophenylhydrazone (CCCP) inhibited artery constriction, but CCCP was used only as a pharmacological tool. Niclosamide is an anthelmintic drug approved by FDA. Niclosamide ethanolamine (NEN) is a salt form of niclosamide and has been demonstrated to uncouple mitochondrial oxidative phosphorylation.

Azo polymeric micelles designed for colon-targeted dimethyl fumarate delivery for colon cancer therapy.

Unlabelled: Colon-targeted drug delivery and circumventing drug resistance are extremely important for colon cancer chemotherapy. Our previous work found that dimethyl fumarate (DMF), the approved drug by the FDA for the treatment of multiple sclerosis, exhibited anti-tumor activity on colon cancer cells. Based on the pharmacological properties of DMF and azo bond in olsalazine chemical structure, we designed azo polymeric micelles for colon-targeted dimethyl fumarate delivery for colon cancer therapy.

GDF11/BMP11 activates both smad1/5/8 and smad2/3 signals but shows no significant effect on proliferation and migration of human umbilical vein endothelial cells.

GDF11/BMP11, a member of TGF-β superfamily, was reported to rejuvenate heart, skeletal muscle and blood vessel architecture in aged mice. However, the rejuvenative effects of GDF11 were questioned recently. Here, we investigated the effects of GDF11 on smad and non-smad signals in human umbilical vein endothelial cells (HUVECs) and the effects of GDF11 on proliferation and migration of HUVECs and primary rat aortic endothelial cells (RAECs).

Oestrogen inhibits BMP4-induced BMP4 expression in cardiomyocytes: a potential mechanism of oestrogen-mediated protection against cardiac hypertrophy.

Background And Purpose: Oestrogen inhibits cardiac hypertrophy and bone morphogenetic protein-4 (BMP4) induces cardiac hypertrophy. Here we have studied the inhibition by oestrogen of BMP4 expression in cardiomyocytes.

Experimental Approach: Cultures of neonatal rat cardiomyocytes were used in in vitro experiments.

(4-[6-(4-isopropoxyphenyl)pyrazolo [1,5-a]pyrimidin-3-yl] quinoline) is a novel inhibitor of autophagy.

Background And Purpose: Autophagy is an important intracellular degradation system, which is related to various diseases. In preliminary experiments we found that D4-[6-(4-isopropoxyphenyl)pyrazolo [1,5-a]pyrimidin-3-yl] quinoline (DMH1) inhibited autophagy responses. However DMH1 also inhibits the signalling pathway activated by bone morphogenetic protein-4 (BMP4).

Bone morphogenetic protein-2 antagonizes bone morphogenetic protein-4 induced cardiomyocyte hypertrophy and apoptosis.

Our previous work showed that the expression of bone morphogenetic protein-4 (BMP4) was up-regulated in pathological cardiac hypertrophy models and BMP4 induced cardiomyocyte hypertrophy and apoptosis. Bone morphogenetic protein-2 (BMP2) and BMP4 share greater than 80% amino acid homology and there exists an interaction between BMP2 and BMP4, so the aim of the present study was to elucidate the changes of BMP2 in the cardiac hypertrophy models and the effects of BMP2 on BMP4-induced cardiomyocyte hypertrophy and apoptosis. The in vivo cardiac hypertrophy models were induced by pressure-overload and swimming exercise in mice.
