Colimitation assessment of phytoplankton growth using a resource use efficiency approach in the Bay of Seine (French-English Channel).

Eutrophication and dystrophy are two of the main problems affecting coastal ecosystems. In the Bay of Seine, phosphorus (P) inputs from the Seine estuary have been largely reduced in the last decade, in contrast to nitrogen (N), which leads to high N/P ratio inputs. To study the effect of dystrophy, an enrichment bioassay using water sampled from the Bay of Seine was repeated 19 times over a period of 18 months with six different enrichments.

Coupling high frequency monitoring and bioassay experiments to investigate a harmful algal bloom in the Bay of Seine (French-English Channel).

Coastal ecosystems are increasingly threatened by eutrophication and dystrophy. In this context, the full pattern of a bloom dominated by the dinoflagellate, Lepidodinium chlorophorum, was investigated by a high frequency monitoring buoy equipped with sensors allowing nutrients and photosynthesis measurements. An increase of the N/P ratio affected phytoplankton physiology leading to bloom collapse with a slight oxygen depletion.

Receiving or not receiving acupuncture in a trial: the experience of participants recovering from breast cancer treatment.

Objective: To explore the experience of breast cancer patients who either received acupuncture or were allocated to the control group.

Methods: Focus group/interviews nested within our multi-site randomised controlled trial. Participants were recruited from the standard care and experimental arm.

Toxoplasmosis among pregnant women: high seroprevalence and risk factors in Kinshasa, Democratic Republic of Congo.

Objective: To determine the seroprevalence of toxoplasmosis in pregnant women, as well as the proportion of acutely infected and risk factors in the Democratic Republic of Congo.

Methods: Thirty maternities in Kinshasa were randomly selected and women attending antenatal consultation were invited to participate. They were interviewed with a structured questionnaire about known risk factors (age, meat consumption, contact with soil, and presence of cat) and a venous blood sample was taken.

Pathology of the capsular and synovial hip nerves in chronic hip diseases.

Nerves of the synovial membrane and of the capsule of the hip have been studied with the usual techniques of optical neuropathology. We studied 52 hips from 46 patients: 13 hips of post-fracture states of the femoral neck, 13 hips of idiopathic osteonecrosis, 6 hips of rheumatoid arthritis, 6 hips of ankylosing spondylitis and 14 hips of osteoarthrosis. Small capsular and synovial nerves mainly located close to blood vessels are modified by the lesions of the surrounding tissue (inflammatory, vascular, traumatic and mechanical disturbances).
