[Mentalization of conflicts in group therapy: Destructivity and survival in the benefit of cohesion].

The high prevalence of personality disorders, along with their substantial functional impact, are important societal issues, which must be addressed by mental health services. Many treatments have shown significant benefits and have contributed to alleviate the difficulties tied to these disorders. Mentalization-based therapy (MBT), which is constituted of a group therapy modality, is an evidence-based treatment of borderline personality disorder.

Deep ocean microbial communities produce more stable dissolved organic matter through the succession of rare prokaryotes.

The microbial carbon pump (MCP) hypothesis suggests that successive transformation of labile dissolved organic carbon (DOC) by prokaryotes produces refractory DOC (RDOC) and contributes to the long-term stability of the deep ocean DOC reservoir. We tested the MCP by exposing surface water from a deep convective region of the ocean to epipelagic, mesopelagic, and bathypelagic prokaryotic communities and tracked changes in dissolved organic matter concentration, composition, and prokaryotic taxa over time. Prokaryotic taxa from the deep ocean were more efficient at consuming DOC and producing RDOC as evidenced by greater abundance of highly oxygenated molecules and fluorescent components associated with recalcitrant molecules.

[Reflections on mentalization-based treatment and its adaptation for men presenting a narcissistic personality disorder and a not otherwise specified personality disorder].

Narcissistic personality disorder (NPD) and not otherwise specified personality disorder (borderline and narcissistic) are major mental health problems for men. These pathologies predispose patients to significant relational difficulties which are characterised by intense reactions to perceived threats to the self-esteem and an impaired empathic ability. Understanding these disorders as affect dysregulation stimulated by shame, the author presents how patients in this context are prone to lose their capacity to mentalize.

Impact of sideways and bottom-up control factors on bacterial community succession over a tidal cycle.

In aquatic systems, bacterial community succession is a function of top-down and bottom-up factors, but little information exists on "sideways" controls, such as bacterial predation by Bdellovibrio-like organisms (BLOs), which likely impacts nutrient cycling within the microbial loop and eventual export to higher trophic groups. Here we report transient response of estuarine microbiota and BLO spp. to tidal-associated dissolved organic matter supply in a river-dominated estuary, Apalachicola Bay, Florida.

Enhancement of orimulsion biodegradation through the addition of natural marine carbon substrates.

Orimulsion is a bitumen-based heavy fuel that is a less expensive alternative to traditional fuel oils. However, because its density is intermediate between that of freshwater and seawater, in the event of a spill, the fuel could strand in the sediments. Previous work indicated that only 0.
