Splenic injury associated with colonoscopy in hospitalized patients: Incidence, risk factors, management, and outcome.

The frequency of splenic injuries due to coloscopy is largely unknown. Therefore, the aim of this study was to give estimate the risk for hospitalized patients. Using the administrative database from a health insurance company with more than 10 million insured subjects, patients undergoing inpatient colonoscopy associated with a splenic injury within 2 weeks were retrieved from the administrative records based upon OPS (comparable to International Classification of Procedures in Medicine) and ICD-10 codes.

Nicotiana tabacum: An Update on PEG-Mediated Plastid Transformation.

Stable plastid transformation in Nicotiana tabacum has been achieved by using two different methods, the biolistic method, using a particle gun, and the polyethylene glycol (PEG)-mediated transformation. PEG-mediated plastid transformation involves the treatment of isolated protoplasts (plant cells without cell wall) with PEG in the presence of DNA. We have previously shown that in Nicotiana tabacum both methods are equally efficient.
