Slc6a3-dependent expression of a CAPS-associated Nlrp3 allele results in progressive behavioral abnormalities and neuroinflammation in aging mice.

Background: An association between neuroinflammation and age-related neurologic disorders has been established but the molecular mechanisms and cell types involved have not been thoroughly characterized. Activity of the proinflammatory NLRP3 inflammasome is implicated in Alzheimer's and Parkinson's disease and our recent studies in patients suggest that dopaminergic neurons within the degenerating mesencephalon express NLRP3 throughout the progression of PD. Here, we directly test the impact of enhanced inflammasome activity in mesencephalic neurons by characterizing motor function, tissue integrity, and neuroinflammation in aging mice harboring hyperactivating mutations within the endogenous murine Nlrp3 locus, enabled only in cells expressing the dopaminergic neuron-specific Slc6a3 promoter.

Efficacy of Oral Cryotherapy During Oxaliplatin Infusion in Preventing Oral Thermal Hyperalgesia: A Randomized Trial.

Background: Chemotherapy-induced oral thermal hyperalgesia (OTH) is a common and debilitating side effect of platinum-based anticancer agents. This study evaluated the efficacy of oral cryotherapy in preventing OTH during oxaliplatin chemotherapy infusion.

Methods: Patients with gastrointestinal cancer treated with biweekly oxaliplatin (85 mg/m2 over 120 minutes) at Abramson Cancer Center at the University of Pennsylvania were randomized to receive oral cryotherapy (ice chips) during oxaliplatin infusion or standard-of-care treatment.

expression in mesencephalic neurons and characterization of a rare polymorphism associated with decreased risk of Parkinson's disease.

Neuroinflammation is a well-characterized pathophysiology occurring in association with the progression of Parkinson's disease. Characterizing the cellular and molecular basis of neuroinflammation is critical to understanding its impact on the incidence and progression of PD and other neurologic disorders. Inflammasomes are intracellular pro-inflammatory pattern-recognition receptors capable of initiating and propagating inflammation.

Fate of Triclosan in Irrigated Soil: Degradation in Soil and Translocation into Onion and Tomato.

This study determined the fate of triclosan, a prevalent wastewater contaminant in recycled waters and surface streams, when soil and crop plants were irrigated at environmentally relevant concentrations. Soil triclosan concentrations were monitored in an 8-wk and in a 16-wk study without plants to determine triclosan degradation. Onion ( O.
