Detection of Medication Taking Using a Wrist-Worn Commercially Available Wearable Device.

Purpose: Medication nonadherence is a persistent and costly problem across health care. Measures of medication adherence are ineffective. Methods such as self-report, prescription claims data, or smart pill bottles have been used to monitor medication adherence, but these are subject to recall bias, lack real-time feedback, and are often expensive.

Antagonism of the transient receptor potential melastatin‑2 channel leads to targeted antitumor effects in primary human malignant melanoma cells.

Melanoma continues to be the most aggressive and devastating form of skin cancer for which the development of novel therapies is required. The present study aimed to determine the effects of antagonism of the transient receptor potential melastatin‑2 (TRPM2) ion channel in primary human malignant melanoma cells. TRPM2 antagonism via use of the antifungal agent, clotrimazole, led to decreases in cell proliferation, as well as dose‑dependent increases in cell death in all melanoma cell lines investigated.

Tumor necrosis factor-α elevates neurite outgrowth through an NF-κB-dependent pathway in cultured adult sensory neurons: Diminished expression in diabetes may contribute to sensory neuropathy.

The presence of a proinflammatory environment in the sensory neuron axis in diabetes was tested by measuring levels of proinflammatory cytokines in lumbar dorsal root ganglia (DRG) and peripheral nerve from age matched control and streptozotocin (STZ)-induced diabetic rats. The levels of tumor necrosis factor-α (TNFα) and other cytokines were diminished in lumbar DRG from diabetic animals. Consequently, we tested the hypothesis that TNFα modulated axonal plasticity in adult sensory neurons and posited that impairments in this signal transduction pathway may underlie degeneration in diabetic sensory neuropathy.

Nuclear factor-kappaB activation in axons and Schwann cells in experimental sciatic nerve injury and its role in modulating axon regeneration: studies with etanercept.

Early inflammatory events may inhibit functional recovery after injury in both the peripheral and central nervous systems. We investigated the role of the inflammatory tumor necrosis factor/nuclear factor-kappaB (NF-kappaB) axis on events subsequent to sciatic nerve crush injury in adult rats. Electrophoretic mobility shift assays revealed that within 6 hours after crush, NF-kappaB DNA-binding activity increased significantly in a 1-cm section around the crush site.

Inhibition of gene markers of fibrosis with a novel inhibitor of transforming growth factor-beta type I receptor kinase in puromycin-induced nephritis.

SB-525334 (6-[2-tert-butyl-5-(6-methyl-pyridin-2-yl)-1H-imidazol-4-yl]-quinoxaline) has been characterized as a potent and selective inhibitor of the transforming growth factor-beta1 (TGF-beta1) receptor, activin receptor-like kinase (ALK5). The compound inhibited ALK5 kinase activity with an IC(50) of 14.3 nM and was approximately 4-fold less potent as an inhibitor of ALK4 (IC(50) = 58.

Activation of nuclear factor-kappaB via endogenous tumor necrosis factor alpha regulates survival of axotomized adult sensory neurons.

Embryonic dorsal root ganglion (DRG) neurons die after axonal damage in vivo, and cultured embryonic DRG neurons require exogenous neurotrophic factors that activate the neuroprotective transcription factor nuclear factor-kappaB (NF-kappaB) for survival. In contrast, adult DRG neurons survive permanent axotomy in vivo and in defined culture media devoid of exogenous neurotrophic factors in vitro. Peripheral axotomy in adult rats induces local accumulation of the cytokine tumor necrosis factor alpha (TNFalpha), a potent activator of NF-kappaB activity.

Gender differences in methamphetamine-induced mRNA associated with neurodegeneration in the mouse nigrostriatal dopaminergic system.

In this report female and male CD-1 mice were treated with a neurotoxic regimen of methamphetamine (MA) to compare gender differences in striatal dopamine depletion and concordant changes in mRNA markers of the transforming growth factor-beta injury response associated with neurodegeneration. Striatal dopamine concentrations of MA-treated female mice were less depleted and significantly greater than that of identically treated males. Associated with this gender difference in striatal dopamine depletion were significantly decreased mRNA levels of plasminogen activator inhibitor-1 and a trend for increased (p = 0.
