Highly efficient photocatalytic oxygenation reactions using water as an oxygen source
Fukuzumi, Shunichi,Kishi, Takashi,Kotani, Hiroaki,Lee, Yong-Min,Nam, Wonwoo Nature Publishing Group 2011 Nature chemistry Vol.3 No.1
The effective utilization of solar energy requires photocatalytic reactions with high quantum efficiency. Water is the most abundant reactant that can be used as an oxygen source in efficient photocatalytic reactions, just as nature uses water in an oxygenic photosynthesis. We report that photocatalytic oxygenation of organic substrates such as sodium p-styrene sulfonate occurs with nearly 100% quantum efficiency using manganese(III) porphyrins as an oxygenation catalyst, [Ru<SUP>II</SUP>(bpy)<SUB>3</SUB>]<SUP>2+</SUP> (bpy?=?2,2??bipyridine) as a photosensitized electron-transfer catalyst, [Co<SUP>III</SUP>(NH<SUB>3</SUB>)<SUB>5</SUB>Cl]<SUP>2+</SUP> as a low-cost and weak one-electron oxidant, and water as an oxygen source in a phosphate buffer solution (pH?7.4). A high-valent manganese-oxo porphyrin is proposed as an active oxidant that effects the oxygenation reactions.
Successful introduction of modified dorsolumbar epidural anesthesia in a bovine referral cent

This study describes the successful use of modified dorsolumbar epidural anesthesia with a fixed volume of anesthetic in a bovine referral center. Among the 130 Holstein cattle scheduled for flank surgery, 90 cattle received a mixed anesthetic consisting of 1 ml of xylazine hydrochloride and 3 ml of lidocaine hydrochloride by modified dorsolumbar epidural anesthesia. Eighteen cattle with dehydration and/or lameness received a mixed anesthetic containing 0.5 ml of xylazine and 3 ml of lidocaine. Infiltration anesthesia was performed in 22 cattle whose epidural space could not be reached in order to perform the flank surgery. The surgeries began about 12 min after the administration of the anesthetic and lasted for about 36 min. The modified method using a fixed volume of anesthetic was successfully introduced and effectively used in a bovine referral center. This modified method will allow veterinarians to save time and effort, thus lowering the cost of each surgery.
