Evaluating the sensitivity of a chronic plant bioassay relative to an independently derived predicted no-effect thresholds to support risk assessment of very hydrophobic organic chemicals.

Environmental risk assessments of very hydrophobic organic compounds (VHOCs) in soils are often difficult because multiple processes (e.g., sorption, volatilization, biodegradation) can complicate the interpretation of results.

Biopreservation and reversal of oxidative injury during blood storage by a novel curcumin-based gel formulation.

Blood storage lesion induces cytosolic and membrane changes driven in part by hemoglobin (Hb) oxidation reactions within red blood cells (RBCs). A novel gel formulation containing the antioxidant curcuminoids in a biocompatible solvent system was used to deliver curcumin into RBCs. Incubation of peroxide treated RBCs stored in PBS with curcumin gel led to a reduction in prooxidant ferrylHb and recovery in ATP.

Activity-Based DNA-Encoded Library Screening for Selective Inhibitors of Eukaryotic Translation.

Small molecule probes exist for only ∼2% of human proteins because most lack functional binding pockets or cannot be assayed for high-throughput screening. Selective translation modulation circumvents canonical druggability and assay development constraints by using in vitro transcription-translation (IVTT) as a universal biochemical screening assay. We developed an IVTT activity assay by fusing a GFP reporter to various target gene sequences and screened the target sequences for inhibitors in microfluidic picoliter-scale droplets using a 5,348-member translation inhibitor DNA-encoded library (DEL).

Specific vegetable types are associated with lower long-term risk for late-life dementia: the Perth Longitudinal Study of Aging Women.

This study examined the relationship between total vegetable intake, including specific vegetable types with long-term late-life dementia (LLD) risk in older Australian women. 1206 community-dwelling older women aged ≥70 years were included. Consumption of total vegetable intake and vegetable types (yellow/orange/red [YOR], cruciferous, allium, green leafy vegetables [GLV], and legumes) were estimated using a validated food frequency questionnaire at baseline (1998).
