BACKGROUND Analgesics, including opioids and non-steroid anti-inflammatory drugs reduce postoperative pain. However, little is known about the quantitative effects of these drugs on cortical activity induced by nociceptive stimulation. The aim of the present study was to determine the neural activity in response to a nociceptive stimulus and to investigate(More)
Simple rain-shelter cultivation is normally applied during the grape growth season in continental monsoon climates aiming to reduce the occurrence of diseases caused by excessive rainfall. However, whether or not this cultivation practice affects the composition and concentration of phenolic compounds in wine grapes remains unclear. The objective of this(More)
4-Alkyl-substituted 1,4-dihydropyridines (DHP) exhibit inhibitory activity toward certain cytochrome P450 enzymes (P450) during their biotransformation by these enzymes, which is called mechanism-based inactivation. Though much experimental evidence had proved the essentiality of alkyl radical for P450 inactivation, the underlying mechanism of such radical(More)
BACKGROUND Airway management is critical in patients with cervical spondylosis, a population with a high incidence of difficult airway. Intubation with Shikani Optical Stylet (SOS) has become increasingly popular in difficult airway. We compared the effects of intubation with SOS versus Macintosh laryngoscope (MLS) in patients undergoing surgery for(More)
This study investigated the effect of rain-shelter cultivation on the biosynthesis of flavonoids and volatiles in grapes, with an aim of determining whether rain-shelter application could help to improve the sensory attributes and quality of grapes. Vitis vinifera L. Chardonnay grapes, grown in the Huaizhuo basin region of northern China, were selected(More)
This study aimed to explore the effect of attenuated UV radiation around grape clusters on the volatile profile of Cabernet Sauvignon grapes (Vitis vinifera L. cv.) under field conditions. Grape bunches were wrapped with two types of polyester films that cut off 89% (film A) and 99% (film B) invisible sunlight of less than 380 nm wavelength, respectively.(More)
N-benzyl-N-cyclopropylamine (BCA) has been attracting great interests for decades for its partial suicide inactivation role to cytochrome P450 (P450) via a ring-opening mechanism besides acting as a role of normal substrates. Understanding the mechanism of such partial inactivation is vital to the clinical drug design. Thus, density functional theoretical(More)
