Heterocyclic amines (HAs) were determined in several of the most frequently eaten meat dishes in Spain such as fried beef hamburger, fried pork loin, fried chicken breast, fried pork sausages, griddled chicken breast, griddled lamb steak and griddled beef steak. All of the products tested were household cooked. The HAs were analysed in the selected meat dishes using an analytical method based on solid-phase extraction followed by liquid chromatography coupled to tandem mass spectrometry. DMIP, MeIQx, 4,8-DiMeIQx, Norharman, Harman, PhIP, Trp-P-1, AαC and MeAαC were the amines most frequently found at concentrations of up to 47 ng g−1 of cooked meat. Glu-P-2, IQ, MeIQ, Glu-P-1, 7,8-DiMeIQx and Trp-P-2 were only found in a few of the meat dishes and their concentrations were lower than 1 ng g−1 of cooked meat. The highest amounts of HAs, especially PhIP and DMIP, were formed in fried chicken breast and the lowest were formed in fried beef hamburger and in fried pork sausages. Daily intake of HAs in Spain was estimated at 606 ng of mutagenic HAs per capita and day, DMIP and PhIP being the main contributors. [Copyright &y& Elsevier]

A model system based on a commercial meat flavour was used to evaluate the formation of heterocyclic amines, simulating the application of this seasoning in household cooking. The effects of different treatments in both dry and aqueous conditions were studied. The lyophilized meat flavour extract was heated at temperatures ranging between 100 and 200 °C for times ranging from 10 min to 2 h. Similarly, an aqueous suspension of the extract was heated at 175 °C for 1, 2 and 3 h. Precursors of HAs, such as creatinine, glucose, and the amino acids glycine, alanine and phenylalanine were added to the meat extract and their effect was tested by heating the mixture at 200 °C for 30 min, when dry conditions were used, and at 175 °C for 2 h in wet systems. All conditions led to the formation of HAs, PhIP being the amine that was detected at the highest level of concentration in most model systems (i.e. 173 ng g−1 at 200 °C, 30 min). Moreover, the addition of creatinine and amino acids to the meat extract flavour produced an important increase in IQ and MeIQx content. [Copyright &y& Elsevier]

The kinetics of adhesion of Listonella anguillarum cells to skin, intestinal and gill mucus suspensions of gilt-head seabream was studied. A Langmuir adsorption isotherm was calculated, and the results obtained indicated that this microorganism showed a saturation kinetics. The pretreatment of the mucus suspensions with a surface extract obtained from L. anguillarum cells promoted a very important inhibition of the number of adhered bacteria to the different mucus suspensions. The potential role of surface structures on the adhesion of L. anguillarum to mucus of gilt-head seabream is discussed. [ABSTRACT FROM AUTHOR]

Similar populations have been observed between the A and X states of the CN radical, formed in the C+N2O chemical reaction. Relative vibrational populations were measured by laser-induced fluorescence (X state) and chemiluminescence (A state). The electronic branching ratio was then obtained by assuming a Boltzmann equilibrium between the v‘=4–6 and v’=1–4 levels of the X and A states. This assumption was checked by absolute calibration of the number densities of both states. About 1/3 of the radicals were found in the A state. [ABSTRACT FROM AUTHOR]

The Rydberg spectrum of Na2 has been shown previously to alternate when increasing energy between ‘‘stroboscopic fringes’’ which correspond to a well known separable Hund’s coupling case (a), and a complex, unidentifiable intermediate coupling. We use this system as a prototypic example to test some current ideas on the correspondence between classical chaos and properties of quantum spectra. We first determine the phase space structure and transition to chaos in classical mechanics. We then determine the change in line intensities and level spacing statistics in quantum mechanics. We show that this system has the expected behavior in the semiclassical limit in the presence of classical chaos, except for a peculiarity in level spacing statistics, but that this behavior is not a signature of chaos, since the same system shows similar behavior for some values of the parameters which correspond to a nonchaotic situation in classical mechanics. We discuss also some problems related to the nonvalidity of the semiclassical limit. [ABSTRACT FROM AUTHOR]

Introduction/Background In France, the notion of care pathway is enshrined in the circular of March, 2012 relative to the organization of care for patients’ victim of stroke. Material and method The rehabilitation-reinsertion mobile team of the pole Saint-Helier (EM2R) was created in 2012 in this context, with support from the Regional Health Agency of Brittany. The main mission of this newly created team is to implement the necessary devices to facilitate the home returning of people hospitalized after a neurological event or maintain home people with neurological disorders (more than 200 coverage a year). The neurodegenerative diseases plan of 2014–2019 points, especially in its 15th measure, that we shall remove all things slowing down the hospital care access at home for people with neurodegenerative diseases and this no matter where they live. And this is done mainly through mobile teams and home medical care (HAD in France) activities. Results In coherence with the activities recently developed “outside the walls” by the pole Saint Helier (EM2R and telemedicine), the establishment of a HAD-SSR (home medical care of rehabilitation care), further consolidated the healthcare pathway for people with disabilities.This activity has been developing since September, 2017 in relation with the HAD 35 and two rehabilitation centers which provide reeducation professionals’. 15 patients have already been cared, mostly persons with stroke. Conclusion The aim is to ensure a global, coordinated and specialized care by bringing to patients’ home a variety of expertise in the field of rehabilitation: doctors of physical medicine and rehabilitation, physiotherapists, occupational therapists, speech therapists, neuropsychologists… and to propose an additional alternative to hospitalization in rehabilitation care when the situation permits it in the healthcare pathway of people with disabilities.
