Effect of Personalized Music Intervention in Mechanically Ventilated Children in the PICU: A Pilot Study.

Objectives: To determine the feasibility of a personalized music intervention with mechanically ventilated patients in the PICU.

Design: Pilot study with a quasi-experimental design.

Setting: Tertiary children's hospital in China with a 40-bed PICU.

Targeting Human Telomerase Reverse Transcriptase by a Simple siRNA Expression Cassette in HepG2 Cells.

Background: Human telomerase reverse transcriptase (hTERT) has become an ideal target for development of anticancer therapy. Small interfering RNAs (siRNAs) are very powerful reagents for gene silencing and show promise for cancer gene therapy. However, only a small number of siRNAs have been demonstrated to be effective.

[Species distribution and coagulation behavior of covalent bonded aluminum-silicon hybrid flocculants].

Covalent bonded aluminum-silicon hybrid flocculants were synthesized by employing tetraethylorthosilicate (TEOS) and two silane coupling agents [diethoxydimethylsilane (DEDMS), gamma-aminopropylmethyldiethoxysilane (APDES)] as silicon sources, respectively. The distribution of Al species was investigated by 27Al NMR method and the coagulation behavior was evaluated by treating synthetic water containing humic acid. The results of 27Al NMR show that silicon source, Si/Al molar ratio and basicity (B) exhibit effect on the Al species distribution.

[Al species distribution of organic silicate aluminum hybrid flocculants by Al-ferron complexation timed spectrophotometric method].

New types of organic silicate aluminum hybrid flocculants were prepared by employing Tetraethylorthosilicat (TEOS), Diethoxydimethylsilane (DEDMS), gamma-Aminopropylmethyldiethoxysilane (APDES) as silicon source. The Al species distribution in these new products was investigated by Al-Ferron complexation timed spectrophotometric method. The results show that silicon source, basicity (B) and Si/Al molar ratio have effect on the Al species distribution.

[DNA polymorphism detection of Cannabis using amplified fragment length polymorphism].

Objective: To screen the AFLP primers with good diversity to distinguish various species of Cannabis.

Methods: The AFLP was used to analyze the genetic diversity of 12 species of Cannabis using 55 primer combinations.

Results: A total of 285 AFLP bands were obtained using five primer combinations with better diversity, among which 99 bands were polymorphic and 10 bands were special, with 47-76 bands amplified in each pair of primers.
