in this article, the immobilization of microsomal membranes on fractosil and hexadecylfractosil by hydrophobic adsorption is reported. microsomes were prepared from rat brain and thecatalytic activity of antimycin a insensitive nadh-cytochrome c reductase (nccr), one of themembrane bound enzymes in the microsomal electron transport chain, was chosen as a representative ofthe microsomal membrane...

Glial cell line-derived neurotrophic factor (GDNF)supports and maintains the neuromuscular system duringdevelopment and through adulthood by promoting neuro-plasticity. The aim of this study was to determine if differentmodes of exercise can promote changes in GDNF expres-sion and neuromuscular junction (NMJ) morphology inslowand fast-twitch muscles. Rats were randomly<l...

A security architecture is a complete frame work that allows to enforce coexisting ap plication and environment speci c security policies by applying security mechanisms in a consistent manner It is argued that such a security architecture can be derived smoothly from an object oriented architec ture such as BirliX BirliX applications run on an abstract ma chine that provides types and instance...

Here we conceive an innovative nanocomposite to endow hybrid perovskites with the easy processability of polymers, providing a tool to control film quality and material crystallinity. We verify that the employed semiconducting polymer, poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV), controls the self-assembly of CH₃NH₃PbI₃ (MAPbI₃) crystalline domains and favors the deposit...

PS1 is important for the ␥-secretase cleavages of the Philadelphia, Pennsylvania 19104 amyloid precursor protein (APP), which results in the production of the A␤ peptide of Alzheimer's disease (AD) (De Strooper et al., 1998). Recent reports, however, show that in addition to the classic ␥-secretase cleav-Summary ages of APP defined by the C terminus of various A␤ species, the PS1/␥-secretase sy...
