During bacterial cannibalism, a differentiated subpopulation harvests nutrients from their genetically identical siblings to allow continued growth in nutrient-limited conditions. Hypothesis-driven imaging mass spectrometry (IMS) was used to identify metabolites active in a Bacillus subtilis cannibalism system in which sporulating cells lyse nonsporulating(More)
Fungal infections are increasing worldwide, including in the aquatic environment. Microbiota that coexist with marine life can provide protection against fungal infections by secretion of metabolites with antifungal properties. Our laboratory has developed mass spectrometric methodologies with the goal of improving our functional understanding of microbial(More)
An In Vitro Comparative Immunogenicity Assessment (IVCIA) assay was evaluated as a tool for predicting the potential relative immunogenicity of biotherapeutic attributes. Peripheral blood mononuclear cells from up to 50 healthy naïve human donors were monitored up to 8 days for T-cell proliferation, the number of IL-2 or IFN-γ secreting cells, and the(More)
Estrogens and leptins act in the hypothalamus to maintain reproduction and energy homeostasis. Neurogenesis in the adult mammalian hypothalamus has been implicated in the regulation of energy homeostasis. Recently, high-fat diet (HFD) and estradiol (E2) have been shown to alter cell proliferation and the number of newborn leptin-responsive neurons in the(More)
OBJECTIVE Penetrating carotid trauma in a hemodynamically stable patient invariably presents with a pseudoaneurysm on initial imaging. Although extremely rare, delayed pseudoaneurysm formation has been reported. The purpose of this paper is to define this rare entity and propose a diagnostic and treatment plan. METHODS We present a case of delayed(More)
Glycation of therapeutic proteins occurs during mammalian cell culture expression and upon administration to patients. Since the chemical attachment of mannose or other sugars via a chemical linker has been shown to increase a protein’s clearance rate in mice through the mannose receptor, we explored the effect of mannose glycation on the clearance of an(More)
