Effects of an Informational Video About Anesthesia on Pre- and Post-Elective Cesarean Section Anxiety and Recovery: A Randomized Controlled Trial.

BACKGROUND Showing an informational anesthesia video can reduce the preoperative anxiety of parturients undergoing elective cesarean section (CS). However, the best method for presenting such videos remains unclear, and whether such videos can reduce the anxiety level of women during the entire perioperative period for CS (including preoperative and postoperative) has not been studied yet. MATERIAL AND METHODS This study was a single-center prospective randomized trial.

Sol-gel molecularly imprinted polymer for selective solid phase microextraction of organophosphorous pesticides.

A sol-gel technique was applied for the preparation of water-compatible molecularly imprinted polymer (MIP) for solid phase microextraction (SPME) using diazinon as template and polyethylene glycol as functional monomer. The MIP-coated fiber demonstrated much better selectivity to diazinon and its structural analogs in aqueous cucumber sample than in distilled water, indicating its potential in real samples. Thanks to its specific adsorption as well as rough and porous surface, the coating revealed rather larger extraction capability than the non-imprinted polymer and commercial fibers.

Multiple headspace solid-phase microextraction using a new fiber for avoiding matrix interferences in the quantitative determination of ethyl carbamate in pickles.

Multiple headspace solid-phase microextraction (HS-SPME) using a novel fiber coated with anilino-methyl triethoxy silicane-methacrylic acid/terminated silicone oil has been introduced as a useful pretreatment technique coupled to gas chromatography-flame ionization detector for the detection of ethyl carbamate in pickles. Anilino-methyl triethoxy silicane and methacrylic acid are put into use simultaneously with the aim to increase the hydrogen interaction strength between ethyl carbamate and the coating. In addition, the new fiber exhibits high thermal stability, good reproducibility, and long lifetime.

Multiple headspace solid-phase microextraction after matrix modification for avoiding matrix effect in the determination of ethyl carbamate in bread.

This study presents the potential of multiple headspace solid-phase microextraction (multiple HS-SPME) for the quantification of analytes in solid samples. Multiple HS-SPME shares the same advantages as SPME. It also enables a complete recovery of the target compound and therefore the matrix effect, which commonly appears in SPME-based analysis, is avoided.

Lipopolysaccharide enhances asymmetrical production of cytokines and nitric oxide by left and right cerebral cortical microglial cells in BALB/C mice.

Lipopolysaccharide (LPS)-induced inflammatory factors production by the cerebral cortical glial cells in two sides of the murine brain are different. To determine if microglial cells, a subset of glial cells, are involved in asymmetric production, interleukin-6 (IL-6), interleukin-1β (IL-1β) and nitric oxide (NO) responses to LPS by microglial cells in the right and left cerebral cortices were examined. Primary microglial cells were isolated from BALB/C neonatal mice, treated with LPS (10 µg ml(-1) ) for 24 h and examined for IL-6, IL-1β and NO production.
