Avoidance behaviour of aquatic macroinvertebrates for real-time detection of micropollutant surge in wastewater effluents.

Micropollutants are regularly detected at the outlets of wastewater treatment plants (WWTPs). Across urban and industrial WWTPs, monitoring directives only require assessment for a handful of chemicals via sampling methods that fail to capture the temporal variability in micropollutant discharge. In this study, we develop a biotest for real-time on-line monitoring of micropollutant discharge dynamics in WWTPs effluents.

Use of Gammarus fossarum (Amphipoda) embryo for toxicity testing: A case study with cadmium.

The effects of environmental contaminants on arthropod embryo stages have been poorly investigated in ecotoxicology. Moreover, many of these tests used hatching success as the sole metric, although it is possible to detect many more subtle effects. After a detailed description of embryogenesis in Gammarus fossarum, the present study reports on the sublethal effects of cadmium (Cd) exposure during embryonic development in G.

Transplantation of testicular tissue in alginate hydrogel loaded with VEGF nanoparticles improves spermatogonial recovery.

Transplantation of cryopreserved immature testicular tissue (ITT) is a promising strategy to restore fertility in young boys facing gonadotoxic treatments. However, up to now, limited spermatogonial recovery has been achieved in xenografting models used to evaluate the potential of cryopreserved tissue transplantation. When comparing avascular xenografts of cryopreserved and fresh human ITT into a mouse model, the number of spermatogonia was significantly reduced, regardless of the cryopreservation procedure used.

Individualized Cognition-Action intervention to prevent behavioral disturbances and functional decline in institutionalized older adults: a randomized pilot trial.

Objective: To evaluate the effectiveness of an individualized Cognition-Action (CA) intervention to reduce behavioral disturbances in severely deconditioned institutionalized old adults.

Design: 12 weeks randomized pilot trial of either individualized Cognition-Action program (n = 24) or routine medical care as control (C, n = 25).

Setting: Long-term care (LTC) of the Geriatric Department from the University State Hospital in Bordeaux, France.

Health-related quality of life in frail institutionalized elderly: effects of a cognition-action intervention and Tai Chi.

No previous studies have explored the effects of mind-body approaches on health-related quality of life (HRQoL) in the frail elderly. Cognition and action are an inseparable whole during functioning. Thus, a new intervention-based approach using familiarity-based movements and a nonjudgmental approach of "cognition-action" was proposed and was tested with Tai Chi on HRQoL in frail institutionalized elderly.
