Factors associated with posttraumatic stress severity and treatment response in a retrospective, naturalistic sample of homicidally bereaved children and young people.

Research on the mental health of homicidally bereaved children and young people is scarce. Despite the importance of timely referral of those at risk of developing severe mental health problems, few convincing risk factors have been identified. The effectiveness of current treatment models is unclear.

Ethnic disparities in mental health problems in New Caledonia and French Polynesia.

Objectives: Indigenous people experience poorer mental health compared to the general population. Socioeconomic gaps partly explain these disparities. However, there is variability between populations and French overseas territories are understudied.

Langmuir-Blodgett Transfer of Nanocrystal Monolayers: Layer Compaction, Layer Compression, and Lattice Stretching of the Transferred Layer.

Grazing incidence small angle X-ray scattering (GISAXS) was used to study the structure and interparticle spacing of monolayers of organic ligand-stabilized iron oxide nanocrystals floating at the air-water interface on a Langmuir trough, and after transfer to a solid support via the Langmuir-Blodgett technique. GISAXS measurements of the nanocrystal arrangement at the air-water interface showed that lateral compression decreased the interparticle spacing of continuous films. GISAXS also revealed that Langmuir-Blodgett transfer of the nanocrystal layers to a silicon substrate led to a stretching of the film, with a significant increase in interparticle spacing.

Chitosan Film as a Replacement for Conventional Sulphur Dioxide Treatment of White Wines: A H NMR Metabolomic Study.

Chitosan-genipin (Ch-Ge) films have been proposed for the replacement of sulfur dioxide (SO) in white wines preservation to circumvent the adverse health consequences caused by SO intake. To assess the effects of different-sized Ch-Ge films (25 and 100 cm) on wine composition compared to SO-treated and untreated wines, nuclear magnetic resonance metabolomics was applied. Relative to SO, 100 cm films induced significant changes in the levels of organic acids, sugars, amino acids, 5-hydroxymethylfurfural, among other compounds, while 25 cm films appeared to induce only small variations.
