“The N-H and C-D bond fission in partially deuterated methylamine, CD3NH2, has been investigated using

vibrationally mediated photodissociation. Jet-cooled action spectra and FG-4592 datasheet Doppler profiles of the H and D photofragments were monitored following similar to 243.1 nm photodissociation of the parent pre-excited to two, three or four N-H stretch quanta. The action spectra were analyzed in terms of simplified local mode/normal mode (LM/NM) and NM models, allowing band assignment and determination of the strong resonances involved in the coupling. The Doppler profiles show that the released H and D photofragments have low translational energy content and that the H is the dominant product, although its yield decreases as higher pre-excited N-H vibrational states are dissociated. The dynamics of the site-dependent bond fission in CD3NH2 is discussed. (C) U0126 2009 American Institute of Physics. [DOI: 10.1063/1.3122983]“
“Sixteen patients with hypopharyngeal carcinoma who underwent

laryngopharyngectomy had immediate reconstruction with a free ileocolic flap to restore voice and swallowing. All patients had satisfactory voice production and swallowing in the early postoperative stage. Maintaining adequate tension and decreasing redundancy of the transferred colon prevented food pooling and provided smooth, rapid swallowing. A wedge resection of the subserosa of the ileocecal valve to increase the intraluminal pressure helped prevent food reflux and provide good phonation. Although this modified technique yielded good initial results, both voice and swallowing deteriorated after concurrent chemoradiotherapy, possibly because of radiation

injury to the transferred bowel.”
“We use negative binomial (NB) models for the magnetic resonance imaging (MRI)-based brain lesion count data from parallel group (PG) and baseline versus treatment (BVT) trials for relapsing remitting multiple sclerosis (RRMS) patients, and describe the associated likelihood ratio (LR), score, and Wald tests. We perform power analyses and sample size estimation using FG-4592 manufacturer the simulated percentiles of the exact distribution of the test statistics for the PG and BVT trials. When compared to the corresponding nonparametric test, the LR test results in 30-45% reduction in sample sizes for the PG trials and 25-60% reduction for the BVT trials.”
“Aim To determine whether the bone mass of young people with Down syndrome may increase, following a 21-week conditioning training programme including plyometric jumps. Method Twenty-eight participants with Down syndrome (13 females, 15 males) aged 10 to 19 years were divided into exercise (DS-E; n=14; eight females, six males mean age 13y 8mo, SD 2y 6mo) and non-exercise (DS-NE; n=14; five females, nine males mean age 15y 5mo, SD 2y 6mo) groups.
