The NOD-, LRR-, and pyrin-domain-containing protein 3 (NLRP3) inflammasome is a node of intracellular stress pathways and a druggable target which integrates mitochondrial stress and inflammatory cascades. While a body of evidence suggests the involvement of the NLRP3 inflammasome in numerous diseases, a lack of reliable measurement techniques highlights the need for a robust assay using small quantities of biological samples. We present a literature overview on peripheral activation of the NLRP3 inflammasome in mood disorders, then outline a process to develop and validate a robust assay to measure baseline and activated intracellular levels of "apoptosis-associated speck-like protein containing a CARD" (ASC) as a key component of an inflammatory profile in peripheral blood mononuclear cells (PBMC).

Aims: To assess comfort levels and knowledge of CLD among recently graduated medical students METHODS: An anonymous survey was distributed to incoming categorical Internal Medicine (IM) interns at a single academic institution during a 2-year period. The survey consisted of 38 Likert-like questions evaluating comfort levels and self-assessed knowledge for several general medicine and liver diseases, as well as 12 multiple-choice questions to objectively test knowledge.

To investigate the effect of sample handling on inflammatory cytokines in serum and highlight challenges with using samples pre-collected from biobanks for biomarker research. Cytokine concentrations (IL-1β, IL-2, IL-6, IL-8, IL-10, TNFα, and IFNγ) were measured in serum samples of 205 patients with bipoldar disorder (BD) from the Mayo Clinic Bipolar Disorder Biobank and 205 non-psychiatric controls from the Mayo Clinic Biobank. As cytokine concentrations varied by recruitment site, models were used to test the effect of clinical variables and pre-processing time on cytokines.

Our letter highlights the disparity between the rising prevalence of chronic liver disease and the proportion of medical students who receive exposure to patients with liver disease as part of their medical education. A more comprehensive survey of clerkship directors is needed to further corroborate this data, which may lead to reforms in medical school curricula to better address the expanding burden of chronic liver disease.

These illnesses are complex and heterogeneous, which is reflected by the complexity of the processes regulating mitochondrial function. Mitochondria are typically associated with energy production; however, dysfunction of mitochondria affects not only energy production but also vital cellular processes, including the formation of reactive oxygen species, cell cycle and survival, intracellular Ca(2+) homeostasis, and neurotransmission.
