Abstract The rapid advent of the piezoelectric microelectromechanical systems (PiezoMEMS) field has created a tremendous demand for low hysteretic thin films on Si. In this work, we present integration epitaxial Pb(Mg 0.33 Nb 0.67 )O 3 -PbTiO (PMN-PT) with Si to enable device fabrication using state art methods. With optimized buffer layers and electronic contacts, high-quality PMN-PT are integ...

Juvenile periodontitis (JP) is a disease characterized by severe gingival infections. PMN from some JP patients exhibit abnormal chemotactic responsiveness when challenged with the synthetic formyl peptide, FMLP. While investigating PMN function in JP, we found a patient in whom abnormal PMN chemotactic responses to FMLP were associated with a defective population of PMN formyl peptide receptor...

Polymorphonuclear neutrophils (PMN) and platelets interact to produce both inflammatory and anti-inflammatory lipid mediators during human disease. Because swine models of human disease are used, it is important to understand the mechanisms involved in the formation of lipid mediators from porcine PMN-platelet interactions. In the present study, we investigated the mechanism of thromboxane (Tx)...

Abstract Antiferromagnetic (AFM) spintronic devices play a vital role in the development of novel due to their attractive features. Herein, interfacial state manipulation AFM IrMn material is investigated by combining ferroelectric single crystal Pb(Mg 1/3 Nb 2/3 ) 0.7 Ti 0.3 O 3 (PMN-PT) with an electric field (E-field)-controlled magnetic moment arrangement film. A PMN-PT/Cu/IrMn/NiFe heteros...

Hemorrhage resulted from severe trauma renders patients susceptible to the development of acute lung injury (ALI). The accumulation of polymorphonuclear neutrophils (PMN) in the lung is a critical event in the development of ALI. PMN migration is a result of a cascade of cellular events, in which PMN, endothelial cells (EC), and macrophages (Mϕ) act in concert. Recent studies explored interrela...

Understanding the relationship between structural characteristics and functional properties of complex relaxor ferroelectric thin films is high interest for designing materials with performances. In this work, structure epitaxial relaxed pulsed-laser-deposited Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMN-xPT; x = 25, 33, 40) on LaNiO3/SrTiO3 substrates analyzed using a variety diffraction spectroscopic techni...

The local and systemic effects of intramammary lipopolysaccharide (LPS) injection on the chemiluminescence (CL) of milk and blood polymorphonuclear leukocytes (PMN) were investigated in six healthy early lactation cows. Clinical signs of acute mastitis such as fever, increased heart rate and a decreased milk production were observed in all cows. Before LPS challenge, the CL activity of milk PMN...

Mechanical deformation of polymorphonuclear leukocytes (PMN) changes their expression of the surface adhesion molecule CD11b/CD18. We tested the hypothesis that mechanical deformation of PMN enhances their adhesiveness. Purified human PMN were deformed through either 5- or 3-microm polycarbonate membrane filters and allowed to adhere to 96-well plates coated with human recombinant intercellular...

Polymorphonuclear cells (PMN) are recruited in early inflammation and are believed to contribute to inflammatory pain. However, studies demonstrating a hyperalgesic role of PMN did not examine selective PMN recruitment or did not document effective PMN recruitment. We hypothesized that hyperalgesia does not develop after chemokine-induced PMN selective recruitment and is independent of PMN infi...
