Motor activity was decreased in Tg mice seven months after CPF treatment. Acquisition learning in a water maze task was not affected, but retention was ameliorated in CPF-exposed Tg mice. Amyloid beta levels increased selleck products in the brains of treated Tg mice eight months after CPF exposure. The results of this study show that some behavioral changes persisted or emerged months after acute CPF exposure, while amyloid beta levels increased. These findings raise concern about the risk of developing neurodegenerative

diseases following moderate exposure to CPF in vulnerable subjects.”
“Phonon densities of states (DOS) for the high performing thermoelectric material, AgPbmSbTe2+m (LAST-m, m = 16, 18, and 20), were extracted from time-of-flight inelastic neutron scattering measurements. The phonon DOS of LAST-18 differs remarkably from LAST-16 and LAST-20 by exhibiting a dramatic broadening of its acoustic modes that increases on heating. This broadening coincides with a minimum in the thermal conductivity, a maximum in the electrical conductivity and Seebeck coefficient, and a related peak in thermoelectric performance.

We argue that the anomalous broadening originates with scattering enhanced by modifications to Te-Ag(Sb) bonds caused by their resonant electronic states falling near the Fermi energy for m = 18. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3581155]“
“Amyotrophic Citarinostat Epigenetics inhibitor lateral sclerosis (ALS) is a progressive neurodegenerative disorder that, for similar to 80% of patients, is fatal within five years of diagnosis. To better understand ALS, animal models have been essential; however, only rodent models of ALS exhibit the major hallmarks of the disease. Here, we report the generation of transgenic zebrafish overexpressing mutant Sod1. The construct used to generate these lines contained the zebrafish sod1 gene and similar to 16 kb of flanking sequences. We generated lines expressing the G93R mutation, as well as lines expressing

wild-type Sod1. Focusing on two G93R lines, we found that they displayed the major phenotypes of ALS. Changes at the neuromuscular selleck chemicals junction were observed at larval and adult stages. In adulthood the G93R mutants exhibited decreased endurance in a swim tunnel test. An analysis of muscle revealed normal muscle force, however, at the end stage the fish exhibited motoneuron loss, muscle atrophy, paralysis and premature death. These phenotypes were more severe in lines expressing higher levels of mutant Sod1 and were absent in lines overexpressing wild-type Sod1. Thus, we have generated a vertebrate model of ALS to complement existing mammal models.”
