Young seedlings of maritime pine (Pinus pinaster Soland in Aït.) were grown in rhizoboxes using intact spodosol soil samples from the southwest of France, in Landes of Gascogne, presenting a large variation of phosphorus (P) availability. Soils were collected from a 93-year-old unfertilized stand
French maritime pine bark extract (FMPBE; Oligopin®), a dietary supplement, is rich in procyanidin. The objective of this study was to determine the effects of FMPBE on bone remodeling in postmenopausal osteopenic women. This randomized, double-blinded, placebo-controlled clinical trial was
Ectomycorrhizal fungi may improve the phosphate nutrition of their host plants by secreting, into the soil solution, acid phosphatases (AcPases) able to release orthophosphate (Pi) from soil organic phosphorus (Po). Using cation-exchange chromatography, we separated four fractions with AcPase
Maritime pine somatic embryos (SEs) require a reduction in water availability (high gellan gum concentration in the maturation medium) to reach the cotyledonary stage. This key switch, reported specifically for pine species, is not yet well understood. To facilitate the use of somatic embryogenesis
BACKGROUND
Pycnogenol(®) extracted from French maritime pine bark (Pinus pinaster Ait. subsp. atlantica) is functional for its antioxidant activity.
OBJECTIVE
To investigate the effects of Pycnogenol(®) on bone mineral density (BMD), trabecular microarchitecture and bone metabolism in ovariectomized
Environmental and occupational exposure to chromium compounds, especially hexavalent chromium [Cr(VI)], is widely recognized as a potential nephrotoxic in humans and animals. Its toxicity is associated with overproduction of free radicals, which induces oxidative damage. Recent evidence indicates
Pycnogenol(®) (PYC) is a standardized bark extract from French maritime pine (Pinus pinaster Aiton). We examined the inhibitory effects of PYC on alveolar bone resorption, which is a characteristic feature of periodontitis, induced by Porphyromonas gingivalis (P. gingivalis) and osteoclast
