Clinical and serotonergic predictors of non-affective acute remitting psychosis in patients with a first-episode psychosis

ACTA PSYCHIATRICA SCANDINAVICA, Issue 1 2009
B. Arranz
Objective:, The study aimed to establish clinical predictors of non-affective acute remitting psychosis (NARP) and assess whether these patients showed a distinct serotonergic profile. Method:, First-episode never treated psychotic patients diagnosed of paranoid schizophrenia (n = 35; 21 men and 14 women) or NARP (n = 28; 15 men and 13 women) were included. Results:, NARP patients showed significantly lower negative symptomatology, better premorbid adjustment, shorter duration of untreated psychosis, more depressive symptomatology and a lower number of 5-HT2A receptors than the paranoid schizophrenia patients. In the logistic regression, the four variables associated with the presence of NARP were: low number of 5-HT2A receptors; good premorbid adjustment; low score in the item ,hallucinatory behaviour' and reduced duration of untreated psychosis. Conclusion:, Our findings support the view that NARP is a highly distinctive condition different from either affective psychosis or other non-affective psychosis such as schizophrenia, and highlight the need for its validation.

An Efficient and Practical Sequential One-Pot Synthesis of Suprofen, Ketoprofen and Other 2-Arylpropionic Acids

ADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 14-15 2008
Helfried Neumann
Abstract A novel sequential double carbonylation to synthesize anti-inflammatory drugs such as Ketoprofen and Suprofen has been developed. Starting from easily available aryl halides and arylboronic acids a one-pot carbonylative Suzuki and hydroxycarbonylation reaction sequence proceeds in good selectivity and high yield in the presence of the palladium/cataCXium® A catalyst system. Applying optimized conditions different 2-arylpropionic acids were synthesized in good yields. [source]


Effect of temperature on the cushioning properties of some foamed plastic materials

PACKAGING TECHNOLOGY AND SCIENCE, Issue 2 2003
Jorge Marcondes
Abstract Foamed plastics are used to cushion products to protect them from shock and vibration. Design data is in most cases derived from laboratory tests, performed under standard conditions. However, during distribution, most shock and vibration events occur under conditions different from those under which the materials were evaluated. Two commonly used foams in packaging, expanded polyethylene and expanded polystyrene, were used to investigate how changes in temperature affect the performance properties of these materials. The materials were tested for shock and vibration under four different temperatures (,17°C, 3°C, 23°C and 43°C). The results show that the properties of expanded polystyrene were the least influenced and those of expanded polyethylene were the most influenced by changes in temperature.

Ill-conditioned Shake-and-Bake: the trap of the false minimum

ACTA CRYSTALLOGRAPHICA SECTION A, Issue 2 2000
Hongliang Xu
The alternation of phase refinement with the imposition of real-space constraints is the essence of the Shake-and-Bake procedure. Typically, these constraints prevent trial structures from falling into local minima. Nevertheless, structures appear to migrate to false minima with significant frequency. These false minima are characterized by the presence of a large `uranium' peak on the corresponding Fourier map. Fortunately, they can be recognized and avoided by considering the values of the minimal function both before and after the application of constraints. However, it appears that finding solutions for large structures is likely also to require parameter-shift conditions different from those that have been found to work well in other space groups. In fact, these conditions often yield an unusually high percentage of solutions. [source]
