For reasonable initial conditions, 2D simulations of our model robustly generate spatially and temporally regular
somites, realistic dynamic morphologies and spontaneous emergence of anterior-traveling find more stripes of Lfng. We show that these traveling stripes are pseudo-waves rather than true propagating waves. Our model is flexible enough to generate interspecies-like variation in somite size in response to changes in the PSM growth rate and segmentation-clock period, and in the number and width of Lfng stripes in response to changes in the PSM growth rate, segmentation-clock period and PSM length.”
“BACKGROUND: Early detection of multidrug-resistant Mycobacterium tuberculosis (MDR-TB) is of primary importance for both patient management and infection control. Optimal
methods for identifying MDR-TB in a timely and affordable manner in resource-limited settings are not yet available.\n\nOBJECTIVES: To evaluate the performance of a low-technology but rapid BKM120 drug susceptibility testing method, the microscopic observation drug susceptibility assay (MODS), in the concurrent detection of M. tuberculosis and its susceptibility to isoniazid (INH) and rifampin (RMP) directly from sputum specimens.\n\nMETHODS: A total of 115 smear-positive TB patients admitted to Abbasia Chest Hospital, Cairo, Egypt, were simultaneously tested using MODS and the BACTEC (TM) MGIT (TM) 960 mycobacterial detection system for the detection of M. tuberculosis and the identification of MDR-TB samples.\n\nRESULTS: MODS detected 112 (97.4%) samples and BACTEC MGIT detected 115 (100%). Of the 115 isolates tested for susceptibility to INH, RMP and MDR-TB, complete agreement between MODS and MGIT results was found among respectively 92.9%, 95.5% and 97.3% of samples. The sensitivity, specificity, and positive
and negative predictive values of MODS in the detection of MDR-TB were respectively 95.3%, 98.6%, Rapamycin 97.6% and 97.1%. MODS results were obtained in a median of 8 days (range 5-21).\n\nCONCLUSION: MODS is an optimal alternative method for timely and affordable identification of MDR-TB in resource-limited settings.”
“Background: dementia is one of the main challenges to our health and social care. This study compares the number and timing of transitions between care settings in the last 2 years of life among older people with and without dementia.\n\nMethods: data were derived from Finnish national registers, and include all those who died in 2002 and 2003 at the age of 70 or older (n = 70,366). Negative binomial regression analyses were used to analyse the impact of dementia on number of transitions among people with and without dementia and to adjust the number for age, gender and other diagnoses.
