A telehealth intervention to promote weight loss and physical activity in overweight primary care patients.

Intervention: This pilot study was a 16-week Telehealth intervention using wearable devices, automated text messaging, and trained health coaching, in primary care clinics of an academic medical center. Thirty patients were enrolled in three cohorts, ages 18-64, BMI > 27, and MVPA < 150 minutes per week. The primary outcome was weight loss per week.

The molecular tweezer CLR01 improves behavioral deficits and reduces tau pathology in P301S-tau transgenic mice.

Background: Molecular tweezers (MTs) are broad-spectrum inhibitors of abnormal protein aggregation. A lead MT, called CLR01, has been demonstrated to inhibit the aggregation and toxicity of multiple amyloidogenic proteins in vitro and in vivo. Previously, we evaluated the effect of CLR01 in the 3 × Tg mouse model of Alzheimer's disease, which overexpresses mutant human presenilin 1, amyloid β-protein precursor, and tau and found that subcutaneous administration of the compound for 1 month led to a robust reduction of amyloid plaques, neurofibrillary tangles, and microgliosis.

Different Inhibitors of Aβ42-Induced Toxicity Have Distinct Metal-Ion Dependency.

Oligomers of amyloid β-protein (Aβ) are thought to be the proximal toxic agents initiating the neuropathologic process in Alzheimer's disease (AD). Therefore, targeting the self-assembly and oligomerization of Aβ has been an important strategy for designing AD therapeutics. In parallel, research into the metallobiology of AD has shown that Zn can strongly modulate the aggregation of Aβ in vitro and both promote and inhibit the neurotoxicity of Aβ, depending on the experimental conditions.
