Genome-wide linkage studies have defined a broad susceptibility region for late-onset Alzheimer's disease on chromosome 12, which contains the Low-Density Lipoprotein Receptor-Related Protein 6 (LRP6) gene, a coreceptor for Wnt signaling. Here, we report the association between common LRP6 variants and late-onset Alzheimer's disease in a multicenter(More)
The anatomic and functional leaf characteristics related to photosynthetic performance of Castanea sativa growing in vitro and in nursery were compared. The irradiance saturated photosynthesis in in vitro grown plantlets was significantly lower compared to nursery plants (65 vs. 722 μmol m−2 s−1). The maximum photosynthetic rate (PNmax) was 4.0 and 10.0(More)
This study was undertaken to measure certain carbon (C) fluxes in a Pinus ponderosa-based silvopastoral systems (SPS) in Patagonia, Chile. Results are compared to those from adjacent 18-year-old managed pine plantations (PPP) and natural prairie (PST). Litter decomposition was determined using the litterbag method. Leached soil solution was collected with(More)
The effects of increased photon flux (100 μmol m−2 s−1), ventilation, and standard in vitro culture (40 μmol m−2 s−1) with no ventilation were investigated on the physiological and histological characteristics of microshoots of Gevuina avellana. The increase in photon flux (light treatment) produced significant improvement in the fluorescence parameters of(More)
Growth and biochemical parameters of two strains of Rhodomonas salina (Cryptophyceae), cultivated under different combinations of irradiance, temperature, and nutrients, were compared. The microalgae were grown in batch mode for 10 days, in f/2 medium at 33‰ salinity. The experimental design was a 25 factorial design with the following variables: nitrate(More)
The unicellular green alga Haematococcus pluvialis accumulates large quantities of astaxanthin, a highly valuable carotenoid pigment in the aquaculture, food, and pharmaceutical industries. Biological diversity within a species with a biotechnological interest allows applying strain selection procedures avoiding genetic manipulation. The aim of this study(More)
In addition to the already known cagA gene, novel genetic markers have been associated with Helicobacter pylori (H. pylori) virulence: the dupA and vacAi genes. These genes might play an important role as specific markers to determine the clinical outcome of the disease, especially the vacAi gene, which has been expected to be a good marker of severe(More)
