Effectiveness of vitamin D for irritable bowel syndrome: A protocol for a systematic review of randomized controlled trial.

Background: Irritable bowel syndrome (IBS) is a prevalent and debilitating condition for patients who experience this disorder. Clinical researches indicate that vitamin D (VD) can help relief the symptoms of IBS. However, no systematic review has addressed this issue yet.

Fabrication of Ag-Nanorods/Polyimide Nanocomposites and Their Thermal, Mechanical, Electrical, and Dielectric Properties.

Silver nanorods/polyimide (Ag-NRs/PI) nanocomposites with high conductivity (An order of magnitude higher than pure PI), frequency-independent dielectric permittivity (3.8-4.2) and low dielectric loss (<0.

Pharmacokinetics of acteoside following single dose intragastric and intravenous administrations in dogs.

Acteoside (verbascoside), a phenylethanoid glycoside widely distributed in various plants, has been shown to have potential activity against Alzheimer's disease, attracting great attentions recently. The present study was designed to develop a selective and sensitive LC-MS/MS method for the determination of acteoside in biological samples and carry our a pharmacokinetic (PK) study in beagle dogs. The PK parameters were calculated using non-compartmental models.

[Effects of glycyrrhizic acid on the growth and acid-producing of Streptococcus mutans in vitro].

Objective: To investigate the antibacterial activity of glycyrrhizic acid against Streptococcus mutans (S. mutans, ATCC 25175) in vitro.

Methods: The minimal inhibitory concentration (MIC) and the minimal bactericidal concentration (MBC) of glycyrrhizic acid against S.

[Effect of decoction of Radix glycyrrhizae on the growth and acid-production of Streptococcus mutans in vitro].

Objective: To investigate the antibacterial activity of decoction of Radix glycyrrhizae against Streptococcus mutans (S. mutans) in vitro.

Methods: The decoction of Radix glycyrrhizae was prepared by boiling particles of Radix glycyrrhizae, the diameter was 0.

[Study on protein extraction methods for Streptococcus mutans].

Objective: To establish an efficient and stable method for protein extraction of Streptococcus mutans.

Methods: The collected bacteria were treated by freeze-thaw and ultrasonic (method 1), ultrasonic (method 2), boiling (method 3), boiling and ultrasonic (method 4), respectively. The index such as state of bacteria broken, concentration of extracted protein and SDS-PAGE of protein were employed to evaluate the effects of above four methods.
