Anemia as an independent predictor of adverse outcomes after carotid revascularization.

Background: Anemia has been identified as a risk factor for postoperative morbidity and mortality after major vascular procedures. Carotid revascularization carries less cardiac morbidity and physiologic stress compared with other vascular interventions. This study evaluated the association between preoperative anemia and major adverse events after carotid revascularization.

Pathological α-synuclein transmission initiated by binding lymphocyte-activation gene 3.

Emerging evidence indicates that the pathogenesis of Parkinson's disease (PD) may be due to cell-to-cell transmission of misfolded preformed fibrils (PFF) of α-synuclein (α-syn). The mechanism by which α-syn PFF spreads from neuron to neuron is not known. Here, we show that LAG3 (lymphocyte-activation gene 3) binds α-syn PFF with high affinity (dissociation constant = 77 nanomolar), whereas the α-syn monomer exhibited minimal binding.
