The polypeptide hormone prolactin (PRL) is increasingly recognized as contributing to the development and progression of human breast cancer. This is supported by epidemiologic studies that found women with high levels of serum PRL are at an increased risk for developing breast cancer. Activation of the prolactin receptor (PRLR) by...
Loss of inhibitory control from descending serotonergic (5-HT) fibers deregulates the excitability of spinal motoneurons and interneurons following spinal cord injury (SCI). Exaggerated synaptic activity triggers long-lasting excitatory postsynaptic potentials (long EPSPs) in hyperexcitable motoneurons to ultimately drive muscle spasms at the chronic stage of SCI. Deep dorsal horn (DDH)...
The impacts of many important technologies are limited by the availability of better-performing materials. One factor limiting the ability of engineers to develop better materials is the speed at which they can search through possible formulations and processing schemes. Recently, machine learning algorithms have emerged as a possible route to...
Age-related cognitive deficits are observed in both humans and animals. Yet, the molecular mechanisms underlying these deficits are not yet fully elucidated. In aged animals, a decrease in intrinsic excitability of pyramidal neurons from the CA1 sub-region of hippocampus is believed to contribute to age-related cognitive impairments, but the molecular...

Analytic jurisprudence is the field organized around the “What is law?” question. When most scholars approach the “What is law?” question, they suppose that the goal of such inquiry is to discover, or to accurately represent, the true nature of law. Consequently, these scholars reject the notion that the goal...
FOXA1 is a FKHD family protein that plays pioneering roles in lineage-specific enhancer activation and gene transcription. Through genome-wide location analyses, here we show that FOXA1 expression and occupancy are, in turn, required for the maintenance of these epigenetic signatures, namely DNA hypomethylation and histone 3 lysine 4 methylation. Mechanistically,...
We define multi-indexed Deligne extensions and multi-indexed log-variations of Hodge structures in the category of (filtered) logarithmic D-modules, via the idea of Bernstein– Sato polynomials and Kashiwara–Malgrange filtrations, generalizing the Deligne canonical extensions of flat vector bundles. We also obtain many comparison results with perverse sheaves via the logarithmic de...
