Prospective, randomized, side-by-side comparison of either the legs or axillae was performed comparing the Soprano XL 810?nm diode in super hair removal (SHR) mode (Alma Lasers, Buffalo Grove, IL) hereafter known as the ��in-motion�� device vs. the LightSheer Duet 810?nm diode laser (Lumenis) hereafter known as the ��single pass�� device. Five laser treatments were performed 6 to 8 weeks apart with 1, 6, selleckchem and 12 months follow-ups for hair counts. Pain was assessed in a subjective manner by the patients on a 10-point grading scale. Hair count analysis was performed in a blinded fashion. There was a 33.5% (SD 46.8%) and 40.7% (SD 41.8%) reduction in hair counts at 6 months for the single pass and in-motion devices respectively (P?=?0.2879). The average pain rating for the single pass treatment (mean 3.6, 95% CI: 2.8 to 4.5) was significantly (P?=?0.0007) greater than the in-motion treatment (mean 2.7, 95% CI 1.8 to 3.5). This data supports the hypothesis that using diode lasers at low fluences and high average power with a multiple pass in-motion technique is an effective method for hair removal, with less pain and discomfort, while maintaining good efficacy. The 6 month results were maintained at 12 month for both devices. Lasers Surg. Med. 46:270�C274, PI3K inhibitor 2014. ? 2014 Wiley Periodicals, Inc. ""5017" "The genome of the soil bacterium Pseudomonas putida strain KT2440 has been erased of various determinants of resistance to antibiotics encoded in its extant chromosome. To this end, we employed a coherent genetic platform that allowed the precise deletion of multiple genomic segments in a large variety of Gram-negative bacteria including (but not limited to) P.?putida. The method is based on the obligatory recombination between free-ended homologous DNA sequences that are released as linear fragments generated upon the cleavage of the chromosome with unique I-SceI sites, added to the segment of interest by the Tryptophan synthase vector system. Despite the potential for a SOS response brought about by the appearance of double stranded DNA breaks during the process, fluctuation experiments revealed that the procedure did not increase mutation rates �C perhaps due to the protection exerted by I-SceI bound to the otherwise naked DNA termini. With this tool in hand we made sequential deletions of genes mexC, mexE, ttgA and ampC in the genome of the target bacterium, orthologues of which are known to determine various degrees of antibiotic resistance in diverse microorganisms. Inspection of the corresponding phenotypes demonstrated that the efflux pump encoded by ttgA sufficed to endow P.?putida with a high-level of tolerance to ��-lactams, chloramphenicol and quinolones, but had little effect on, e.g. aminoglycosides.
