OBJECTIVE The current study examined the efficacy and safety of rasagiline, a selective MAO-B inhibitor, for the treatment of persistent negative symptoms. METHODS Sixty people with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, schizophrenia or schizoaffective disorder, who met a priori criteria for persistent negative symptoms, were randomized to receive rasagiline, ...

Introduction To elucidate compositional changes of the sinoatrial node (SAN) with aging, the authors investigated age-related changes of elements in the SANs of Thai subjects with a wide range of ages. Materials and methods The Thai subjects consisted of 37 men and 36 women, ranging in age from 35 to 91 years (average age=67.713.3 years). The samples of the SANs were obtained by dissecting the ...

Small proteins like amyloid beta (Aβ) monomers are related to neurodegenerative disorders by aggregation to insoluble fibrils. Small angle neutron scattering (SANS) is a nondestructive method to observe the aggregation process in solution. We show that SANS is able to resolve monomers of small molecular weight like Aβ for aggregation studies. We examine Aβ monomers after prolonged storing in d-...
