[Show abstract][Hide abstract] ABSTRACT: We synthesized ruthenium nanoparticles in reverse-micelle solutions using radiation-chemical (under anaerobic conditions) and chemical reduction of ions (in the presence of oxygen). The optical absorption spectra recorded during nanoparticle formation differed depending on the synthesis conditions, storage, and the phenomena of adsorption/desorption on the carrier. The size of ruthenium nanoparticles was determined by atomic force microscopy (AFM) and transmission electron microscopy (TEM). Nanoparticles varied in size, shape, and size distribution according to the experimental conditions. We deposited ruthenium nanoparticles on the Γ-Al2O3 carrier and studied their catalytic activity in an isotopic exchange reaction.

[Show abstract][Hide abstract] ABSTRACT: Combat post-traumatic stress disorder (PTSD) involves significant suffering, impairments in social and occupational functioning, substance use and medical comorbidity, and increased mortality from suicide and other causes. Many veterans continue to suffer despite current treatments. Deep brain stimulation (DBS) has shown promise in refractory movement disorders, depression and obsessive-compulsive disorder, with deep brain targets chosen by integration of clinical and neuroimaging literature. The basolateral amygdala (BLn) is an optimal target for high-frequency DBS in PTSD based on neurocircuitry findings from a variety of perspectives. DBS of the BLn was validated in a rat model of PTSD by our group, and limited data from humans support the potential safety and effectiveness of BLn DBS.
