TET2-loss enhances immediate and time-resolved IFNγ signaling responses across myeloid differentiation.

Signaling responses to cytokines are disrupted in clonal hematopoiesis and myeloid malignancies. To better identify specific signaling response alterations in the presence or absence of TET2, we developed a 36-parameter CyTOF panel of both surface marker and phosphoprotein antigens in murine BM. We show diverse, cell-type specific inflammatory cytokine responses in healthy hematopoietic cells.

PET Quantification in Healthy Humans of Cyclooxygenase-2, a Potential Biomarker of Neuroinflammation.

Cyclooxygenase-2 (COX-2) is present in a healthy brain at low densities but can be markedly upregulated by excitatory input and by inflammogens. This study evaluated the sensitivity of the PET radioligand [C]-6-methoxy-2-(4-(methylsulfonyl)phenyl)--(thiophen-2-ylmethyl)pyrimidin-4-amine ([C]MC1) to detect COX-2 density in a healthy human brain. The specificity of [C]MC1 was confirmed using lipopolysaccharide-injected rats and transgenic mice expressing the human gene, with 120-min baseline and blocked scans using COX-1 and COX-2 selective agents.

Patterns of Maternal Single and Polysubstance Use in the US: A Latent Class Analysis.

Objective: Substance use patterns vary considerably in the general population, yet little is known about patterns before and during pregnancy. The purpose of this study was to describe single substance and polysubstance use (PSU) before and during pregnancy among recent births in the United States (US) and compare exposure patterns.

Methods: We used data from the Pregnancy and Risk Assessment Monitoring System (PRAMS) postpartum survey for 2016-2018 to estimate the prevalence and identify patterns of substance use by participants one to three months before and during pregnancy.

The effectiveness of real-life cognitive and physical interventions on cognitive functioning in healthy older adults: A systematic review of the effects of education and training duration.

Physical and cognitive interventions are deemed the primary methods of improving cognitive functioning in healthy older adults. However, the effectiveness of these interventions is still debated. This systematic review, synthesised findings from the literature on four different types of interventions: physical activities, cognitive training, cognitive stimulation and a combined intervention.

Non-contact confocal calcium imaging of murine corneal nerves.

Abnormal corneal nerve function and associated disease is a significant public health concern. It is associated with prevalent ocular surface diseases, including dry eye disease. Corneal nerve dysfunction is also a common side effect of refractive surgeries, as well as a symptom of diseases that cause peripheral neuropathies.
