OBJECTIVE To analyze the incidence of surgical site infection when the preoperative skin preparation was performed with 10% povidone-iodine and 0.5% chlorhexidine-alcohol. METHODS We conducted a randomized, longitudinal study based on variables obtained from patients undergoing clean and potentially contaminated operations. Those involved were divided into two groups. In group 1 (G1) we inclu...

, number 5 , May 2016 :e 20154500 Participation in global health electives (GHE) by pediatric residents continues to grow. In 2013, more than half of residency programs in the United States offered international electives, and 1 in 15 residents participated in such an experience during that year.1 Pretravel preparation for these experiences has been established as a best practice and should inc...

The influence of various preparation methods on the performance of V-Nb-0 catalysts has been investigated. It was found that the activity and selectivity of a vanadium site depend on the nature of the neighbouring atoms. Vanadium neighbours provide activity, while niobium neighbours provide selectivity. Careful preparation of these catalysts ensures a homogeneous distribution and good mixing of...

Pyrosequencing is a highly effective method for quantitatively genotyping short genetic sequences, but it currently is hampered by a labor-intensive sample preparation process designed to isolate single-stranded DNA from double-stranded products generated by conventional PCR. Here linear-after-the-exponential (LATE)-PCR is introduced as an efficient and potentially automatable method of directl...
