Genetic causes of Alzheimer's disease (AD) include mutations in the amyloid precursor protein (APP), presenilin 1 (PS1), and presenilin 2 (PS2) genes. The mutant APP(K670N,M671L) transgenic line, Tg2576, shows markedly elevated amyloid beta-protein (A beta) levels at an early age and, by 9-12 months, develops extracellular AD-type A beta deposits in the(More)
The initial interaction between microorganisms and substrata is mediated by physicochemical forces, which in turn originate from the physicochemical surface properties of both interacting phases. In this context, we have determined the physicochemical proprieties of all microorganisms isolated from cedar wood decay in an old monument at the Medina of(More)
Transgenic mice expressing heme oxygenase-1 (HO-1) using the neuron-specific enolase promoter were impaired in learning the Morris water maze compared to nontransgenic littermates. The memory of the HO-1 mice for the location of the platform was similarly impaired when tested using a probe trial after 7 training blocks, but performance on visible platform(More)
The initial microorganism adhesion on substrate is an important step for the biofilm formation. The surface properties of the stainless steel and B. cereus were characterized by the sessile drop technique. Moreover, the physicochemical properties of surface adhesion and the impact of bio adhesion to the stainless steel were determined at different time of(More)
Biofilms are communities of microorganisms attached to a surface and included in an extracellular matrix making it resistant to exogenous deleterious agents. The aim of this study is to evaluate the anti-adhesive and anti-biofilm effect of five commercials disinfectants having different active principles (hydrogen peroxide, sodium hypochlorite, isopropyl(More)
