Currently, a lack of information on transporters and enzymes expressed on both BCSFB ...

Fighting Kinase Drug Resistance with Caspase Activators.

Kinase inhibitors are effective cancer therapies. Unfortunately, drug resistance emerges in response to kinase inhibition leading to loss of drug efficacy. In this issue of Cell Chemical Biology, Peh et al. (2018) demonstrate that caspase activators effectively delay onset of resistance to kinase inhibitors and are excellent co-therapeutics for a number of tumor types.

Seeing, Targeting and Delivering with Upconverting Nanoparticles.

Efficient control over drug release is critical to increasing drug efficacy and avoiding side effects. An ideal drug delivery system would deliver drugs in the right amount, at the right location and at the right time noninvasively. This can be achieved using light-triggered delivery: light is noninvasive, spatially precise and safe if appropriate wavelengths are chosen. However, the use of light-...

Prenatal intent and postpartum receipt of long-acting reversible contraception among women receiving medication-assisted treatment for opioid use disorder.

Many women with opioid use disorder (OUD) do not use highly effective postpartum contraception such as long-acting reversible contraception (LARC). We evaluated factors associated with prenatal intent and postpartum receipt of LARC among women receiving medication-assisted treatment (MAT) for OUD.

Mourning our dead: The impact of Mexico's war on drugs on citizens' depressive symptoms.

Research has shown the substantial impact on mental health for victims of drug-related crime in Mexico, especially individuals who have been heavily exposed to violence. However, the effect of drug-related violence in non-victims has been less studied because causal pathways via indirect violence are more ambiguous. We argue that drug-related violence does have an influence on the mental health of...
