Is initial colony morphology-based selection for iPS cells derived from adult fibroblasts substantially improved by temporary UTF1-based selection?
Our data indicate that temporary selection using a genetic UTF1-based system can generate homogenous pluripotent iPS cells that can be maintained without permanent selection pressure.
Annual mass treatment with oral azithromycin may alter the prevalence of drug resistant S pneumoniae in a community. Surprisingly, topical tetracycline may also increase nasopharyngeal pneumococcal resistance. Topical antibiotics may have an effect on extraocular bacterial resistance.
