A new HPLC-DAD method has been developed and validated for the simultaneous analysis of five flavonoids (rutin, quercitrin, quercetin, kaempferol, and isorahamnetin) in rat plasma. Sample pretreatment consisted of a liquid–liquid extraction. The five flavonoids was separated on a kromasil C18 column and recorded at 350 nm. The greatest resolution was achieved with methanol-0.1% formic acid grad...

X.400 and SMTP/MIME are the subject of much canonical debate in the messaging community. Although the general consensus is that X.400 offers better functionality than SMTP/MIME as an E-mail protocol, the decision to use X.400 or SMTP/MIME must be based not only on their functionality but also other issues such as security, systems management, message management, human resources requirements, an...

The authors investigated how expertise in motor skills that require fine postural control, such as gymnastics, influences postural regulation. Gymnasts and nongymnasts performed a postural stabilization task after anterior–posterior destabilization while looking at a target in front of them. The authors recorded and analyzed the center of pressure and the ankle, knee, and hip displacements. Gym...

This study was conducted on a group of male sprinters (n = 8) to compare heart rate (HR) and blood lactate (La) response in 400 m flat and 400 m hurdle running during weekly trial race. Durations of the flat and hurdle races were 51.65 +/- 1.51 and 58.27 +/- 1.97 sec respectively. Peak HR attained at the end of the flat and hurdle races were 192.4 +/- 5.3 and 193.6 +/- 4.1 beats/min, whereas, a...
