A novel repeated inescapable forced swim paradigm (riFS) was developed to assess behavioral responses
to repeated stress in the GluN2BKO mice. For comparison, non-mutant C57BL/6J mice were tested for single-trial forced swim behavior after systemic Ro 25-6981 treatment and for riFS behavior after lesions of the ventromedial prefrontal cortex. riFS-induced alterations in corticolimbic GluN2B expression were JQ1 supplier also examined in C57BL/6J mice. We found that GluN2BKO mice reduced “”despair-like”" behavior in the riFS procedure, as compared to GluN2BFLOX controls. By contrast, GluN2BKO mice showed minimal alterations on anxiety-like or antidepressant-sensitive assays, including the single-trial forced swim test. In C57BL/6J mice, induction of “”despair-like”" responses in the riFS test was attenuated by vmPFC lesions, and was associated with changes in limbic GluN2B expression.
Collectively, these data suggest that cortical GluN2B plays a major role in modulating adaptive responses to stress. Current findings provide further support for GluN2B as a key mechanism underlying stress responsivity, and a novel pharmacotherapeutic target for stress-related neuropsychiatric disorders. this website Published by Elsevier Ltd on behalf of IBRO.”
“Infected aneurysm (IA) of the anterior interosseal artery (AIA), the first branch of the ulnar artery, is an infrequent but serious complication of infectious endocarditis (IE). We report a successful case of excision of IA arising from AIA. In this case, the IA expanded Avapritinib concentration and adhered to the ulnar artery, resulting in occlusion of the ulnar artery. Reconstruction of the ulnar artery was not needed by the preoperative evaluation and
the intraoperative occlusion testing. We discuss surgical treatment of IA following IE in upper extremities. (J Vasc Surg 2011;53:1104-6.)”
“Amyloid beta (A beta) has been proposed to play a central and causative role in the development of Alzheimer’s disease. A beta(25-35), the neurotoxic domain of the full-length A beta, causes learning and memory impairments in rodents. The present study investigated the effects of a single bilateral i.c.v. infusion of pre-aggregated A beta(25-35) (30 nmol/rat) on animals’ performance in the open field, and on arginine metabolic enzymes and metabolites in the CA1, CA2/3, and dentate gyrus (DG) sub-regions of the hippocampus and prefrontal cortex (PFC) at the time point of 6-8 days after A beta infusion. A beta(25-35) rats displayed reduced exploratory activity in the open field relative to the A beta(35-25) (reverse peptide; 30 nmol) rats.
