The loss of both pUL16 and pUL21 in HSV-1-infected cells alters capsid-tegument composition, nuclear membrane architecture, cytoplasmic maturation and cell-to-cell spread.

Previously, we had developed synthetic genomics methods to assemble an infectious clone of herpes simplex virus type-1 (HSV-1) strain KOS. To do this, the genome was assembled from 11 separate cloned fragments in yeast using transformation-associated recombination. Using this method, we generated null mutations in five tegument protein-coding genes as well as different combinations of these mutants.

Fluorescent Molecular Probe for Imaging Hypoxia in 2D Cell Culture Monolayers and 3D Tumor Spheroids: The Cell Membrane Partition Model for Predicting Probe Distribution in a Spheroid.

Compared to cultured 2D cell monolayers, 3D multicellular spheroids are more realistic tumor models. Nonetheless, spheroids remain under-utilized in preclinical research, in part, because there is a lack of fluorescence sensors that can noninvasively interrogate all the individual cells within a spheroid. This present study describes a deep-red fluorogenic molecular probe for microscopic imaging of cells that contain a high level of nitroreductase enzyme activity as a biomarker of cell hypoxia.

Psychological Resilience and Physical Function in Veterans With Chronic Kidney Disease: A Brief Report.

Background: Psychological resilience has been characterized as the ability to recover from stressful life events. Not well studied is whether self-reported measures of psychological resilience are associated with physical function recovery. Therefore, we examined the association of self-reported psychological resilience with longitudinal physical function before and after an acute care encounter.

Prefrontal cortical microglial transcriptome relates to mouse offspring executive function deficits after perinatal opioid exposure in a sex-dependent manner.

Opioid use during pregnancy affects over 7% of pregnancies in the United States. While efforts have been directed at mitigating effects of prenatal opioid exposure acutely in the neonatal period, long-term neurodevelopmental studies in humans remain challenging. Using a preclinical model, we previously found that perinatal morphine (MO) exposure induces sex-dependent executive function deficits in adult offspring, and sexually divergent shifts in microglia phenotype.
