Ultrasound has been shown to modulate the activity of retinal ganglion cells (RGCs) in mice, but the mechanism remains poorly understood. This study aims to address this question.Multi-electrode recordings together with pharmacological methods were used to investigate the possible cellular/circuitry mechanism(s) underlying the neuronal modulation induced by low-frequency (1 MHz), low-intensity (0.

This study aimed to prepare evodiamine-glycyrrhizic acid(EVO-GL) micelles to enhance the anti-hepatic fibrosis activity of evodiamine. Firstly, EVO-GL micelles were prepared with use of thin film dispersion method. With particle size, encapsulation efficiency, loading capacity of micelles and the solubility of evodiamine as the indexes, the effect of different factors on micelles was observed to screen the optimal preparation methods and process.

Breast cancer is ranked as the second leading cause of cancer-related deaths among women. Accumulating evidences have revealed that long non-coding RNAs (lncRNAs) are involved in human tumorigenesis owing to the regulation of essential pathways for tumor initiation and progression. Herein, the current study aimed to explore the regulatory mechanism of lncRNA ZFHX4-AS1 in breast cancer in relation to the Hippo signaling pathway.

Background and Purpose- Trimethylamine N-oxide (TMAO)-a gut derived metabolite-has been shown to be atherogenic. It remains unknown whether TMAO is associated with the risk of first stroke. We aimed to determine the association between serum TMAO levels and first stroke in hypertensive patients without major cardiovascular diseases and examine any possible effect modifiers.

Objective: To investigate the selective inhibitory effect of glycyrrhetinic acid on 4 hepatocellular carcinoma (HCC) cells with different proliferation rates and explore the underlying mechanisms.

Methods: MTT method was used to detect the proliferation rates of 4 HCC cell lines, namely SMMC-7721, SK-HEP1, HEPG2 and HEP3B. Following treatment of the cells with glycyrrhetinic acid (5, 10, 20, 30, 40, and 60 µmol/L), the cell viability was analyzed using MTT assay and the expressions of total ERK protein, p-ERK protein and topoisomerase IIα were detected using Western blotting.

In this study, the total alkaloids of Huangteng were given to the rats by the methods of intragastric administration and tail vein. After the concentration changes of palmatine and jatrorrhizine in the plasma of rats were determined by RP-HPLC, pharmacokinetic parameters and oral bioavailability were calculated by 3P97 software. After the rats were pre-treated with total alkaloid 60 mg•kg⁻¹ by the methods of intragastric administration and tail vein, the main pharmacokinetic parameters were determined as follows: in the intragastric administration group, the Cmax of palmatine and jatrorrhizine were (0.

Pulmonary fibrosis, a progressive and lethal lung disease, is a major therapeutic challenge for which new therapeutic strategies are warranted. Schisandrin B (Sch B) and Glycyrrhizic acid (GA) are the principal active ingredients of Schisandra chinensis and Glycyrrhiza glabra respectively, which have been reported to protect against lung injures. The present study was aimed at exploring the combinatorial therapeutic effects on bleomycin-induced pulmonary fibrosis.

Low frequency ultrasound (<1 MHz) has been demonstrated to be a promising approach for non-invasive neuro-stimulation. However, the focal width is limited to be half centimeter scale. Minimizing the stimulation region with higher frequency ultrasound will provide a great opportunity to expand its application.

Small cell lung cancer (SCLC) remains one of the most aggressive tumors with a poor prognosis. The clinical outcome of SCLC patients has reached its plateau with the existing standard treatment and thus new therapies are urgently required. Accumulating evidences have indicated that doxycycline, a commonly used antibiotic, has antitumor activity against several malignancies.

We meta-analytically summarized the associations of angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism with ACE activity and obstructive sleep apnea syndrome (OSAS) to see whether ACE activity is causally associated with OSAS. Literature search and data abstraction were done in duplicate. Sixteen articles including 2060 OSAS patients and 1878 controls were summarized.
