Host-derived Interleukin 1α induces an immunosuppressive tumor microenvironment via regulating monocyte-to-macrophage differentiation.

Tumor-associated macrophages exhibit high heterogeneity and contribute to the establishment of an immunosuppressive tumor microenvironment (TME). Although numerous studies have demonstrated that extracellular factors promote macrophage proliferation and polarization, the regulatory mechanisms governing the differentiation process to generate phenotypically, and functionally diverse macrophage subpopulations remain largely unexplored. In this study, we examined the influence of interleukin 1α (IL-1α) on the development of an immunosuppressive TME using orthotopic transplantation murine models of breast cancer.

Impact of Pregnancy on the Pharmacokinetics and Metabolism of Nicotinamide in Humans.

In pre-eclampsia models, nicotinamide (NAM) has protective effects in pre-eclampsia and is being evaluated as a therapeutic nutraceutical in clinical studies. NAM undergoes extensive hepatic metabolism by NAM N-methyltransferase to methylnicotinamide (MNA), which is subsequently metabolized to methyl-2-pyridone-5-carboxamide (M2PY) by aldehyde oxidase. However, the pharmacokinetics of NAM and its major metabolites has never been studied in pregnant individuals.

Gender responsivity in the assessment and treatment of offenders.

Risk assessment tools used to assess justice-involved women have been predominantly developed using male offenders, with validations for females having mixed results. Female-specific risk assessment tools are not well established, and validations are limited. In terms of treatment, either programmes in various jurisdictions have been developed specifically for females, or addendums are available to assist in the facilitation of programmes initially developed for male offenders.
