Inflammation-triggered local drug release ameliorates colitis by inhibiting dendritic cell migration and Th1/Th17 differentiation.

Enteric-coated formulations using Eudragit® polymers have been extensively used for delivering drugs to the lower gastrointestinal tract. However, these drug-delivery systems cannot accurately deliver the therapeutic cargoes to colon because of early degradation of the polymers at alkaline pH of the small intestine. Here, we describe a precise method of delivering drugs to inflammation sites in colon using an oral drug delivery system.

Trichloroethylene: Parkinsonism and complex 1 mitochondrial neurotoxicity.

Objective: To analyze a cluster of 30 industrial coworkers with Parkinson's disease and parkinsonism subjected to long-term (8-33 years) chronic exposure to trichloroethylene.

Methods: Neurological evaluations were conducted on the 30 coworkers, including a general physical and neurological examination and the Unified Parkinson's Disease Rating Scale. In addition, fine motor speed was quantified and an occupational history survey was administered.
