The purpose of this investigation was to determine if 30 days of continuous contact lens wear produces a different ocular inflammatory response compared to 30 days of daily wear of Bausch & Lomb® PureVisionTM silicone hydrogel contact lenses. Eighty-five individuals wore these lenses for 30 days continuously in one eye and daily in the contralateral eye. Relative concentrations of 27 cytokines were measured in tear samples collected from the subjects using cytometric bead-based assays. Clinical tests were also conducted to correlate changes in cytokine levels to changes in clinical profiles. This study contributes to a greater understanding of the impact …

Zinc is an essential cation for life that is involved in numerous physiology and pathophysiology processes. Despite its wide use as a cytoprotective agent in medications, its cellular and molecular mechanisms of action have not been well established. In order to define the potential therapeutic benefit of zinc, I used several Cystic Fibrosis (CF) and non-CF human airway epithelial cell lines as models in my studies. Extracellular zinc caused release calcium from the endoplasmic reticulum though zinc-sensitive Gq-coupled receptor(s) that may subsequently modulate ion channels. In addition, zinc also exhibited anti-inflammatory effects. Zinc inhibited pro-inflammatory molecular TNFα-induced cytokine and chemokine …
Protective Mechanisms Of Apoa-I Mimetic Peptide Action In Sepsis-Induced Tissue Injury, Zhenghao Zhang
Protective Mechanisms Of Apoa-I Mimetic Peptide Action In Sepsis-Induced Tissue Injury, Zhenghao Zhang

Sepsis is among the top ten causes of death in the US, and it is associated with severe inflammatory tissue damage and organ dysfunction. Reduced plasma high density lipoprotein (HDL) is associated with increased mortality in septic patients. Since raising plasma apolipoprotein (apo) A-I and HDL may reduce sepsis complications, we tested the hypothesis that the apoA-I mimetic peptide 4F confers similar protective effects in two animal models of sepsis, and explored the possible mechanisms. In endotoxemic rats, inflammatory mediators were significantly induced while blood pressure was significantly reduced by 6hr. The impaired arterial response to vasoconstrictors was related to …
