Adjustable Hyperthermia Response of Self-Assembled Ferromagnetic Fe-MgO Core-Shell Nanoparticles by Tuning Dipole-Dipole Interactions
(2012)The Fe-MgO core-shell morphology is proposed within the single-domain nanoparticle regime as an enhanced magnetically driven hyperthermia carrier. The combinatory use of metallic iron as a core material together with the ... -
Bubble rise dynamics in a viscoplastic material
(2015)The axisymmetric dynamics of a bubble rising in a Bingham fluid under the action of buoyancy is studied. The Volume-of-Fluid (VOF) method is used to solve the equations of mass and momentum conservation, coupled to an ... -
Comparison of the electrophysiological properties of the sheep isolated costal and diaphragmatic parietal pleura
(2007)1. Pleural permeability may contribute to pleural fluid turnover. The transmesothelial resistance (R-TM), is an established surrogate of mesothelial permeability. The aim of the present study was to compare the ... -
Cytokine gene polymorphisms in periodontal disease: a meta-analysis of 53 studies including 4178 cases and 4590 controls
(2008)Aim: We conducted a systematic review and a meta-analysis, in order to investigate the potential association of cytokine gene polymorphisms with either aggressive or chronic periodontal disease. Material and Methods: A ... -
Development and application of competitive ELISA assays for rat LH and FSH
(1999)Rat LH (rLH) and FSH (rFSH) were measured by sensitive and specific competition ELISAs. The rat LH ELISA used rLH-I-9 coated plates, an antiserum against rLH and an antibody against rabbit IgG labeled with peroxidase. Using ... -
Diagnostic accuracy of biomarkers of oxidative stress in parapneumonic pleural effusions
(2011)P>Background The imbalance between oxidants and antioxidants is referred to as oxidative stress and has been associated with various respiratory disorders. The aim of this study was the assessment of 8-isoprostane (8-iso-PGF(2 ... -
The effect of interfacial slip on the dynamics of a drop in flow: Part I. Stretching, relaxation, and breakup
(2012)Using a numerical method based on the boundary-integral technique, we assess the impact of interfacial slip on the dynamics of deformation and breakup of a single drop subjected to a uniaxial extensional flow under ... -
Finite Element Analysis of Externally-Induced Sloshing in Horizontal-Cylindrical and Axisymmetric Liquid Vessels
(2009)Motivated by the earthquake response of industrial pressure vessels, the present paper investigates externally-induced sloshing in horizontal-cylindrical and axisymmetric liquid containers. Assuming ideal and irrotational ... -
How wall properties control diffusion in grooved nanochannels: a molecular dynamics study
(2013)The effect of a geometrically-rough wall, amplified by its degree of wettability and stiffness on diffusion coefficient in cases of fluid flow in nanochannels is studied by non-equilibrium molecular dynamics. Diffusion ... -
Increased oxidative stress in exudative pleural effusions - A new marker for the differentiation between exudates and transudates?
(2005)Study objectives: Oxidative stress has been associated with various respiratory disorders. We tested the hypothesis that exudates would present higher levels of oxidative stress compared to transudates, expressing the ... -
Luteinizing hormone response to gonadotrophin-releasing hormone in normal women undergoing ovulation induction with urinary or recombinant follicle stimulating hormone
(1998)Oestradiol enhances pituitary sensitivity to gonadotrophin-releasing hormone (GnRH) in normal women, while in women undergoing ovulation induction the putative factor gonadotrophin surge attenuating factor (GnSAF) attenuates ... -
Matrix Metalloproteinase Levels in the Differentiation of Parapneumonic Pleural Effusions
(2010)Background: Matrix metalloproteinases (MMPs) have been implicated in the escalation of fibrosis and remodeling which are central to the subsequent progression of a parapneumonic pleural effusion to empyema. Objectives: The ... -
Matrix Metalloproteinases in Respiratory Diseases: From Pathogenesis to Potential Clinical Implications
(2009)Matrix metalloproteinases (MMPs) are zinc-endopeptidases responsible for degradation of the extracellular matrix (ECM) components including basement membrane collagen, interstitial collagen, fibronectin, and various ... -
Parameters Affecting Slip Length at the Nanoscale
(2013)We investigate liquid flows in various nanochannels and present the effect of all physical parameters affecting slip length at the boundary using molecular dynamics simulations. Our computational model shows that slip ... -
Pin-assisted resin infiltration of porous substrates
(2015)We analyze computationally the process of pin-assisted resin infiltration of porous substrates. In such a process, a porous substrate is pulled over a staggered array of stationary pins. A wedge-shaped fluid region forms ... -
The recombinant subdomain IIIB of human serum albumin displays activity of gonadotrophin surge-attenuating factor
(2004)BACKGROUND: Gonadotrophin surge-attenuating factor (GnSAF) is an as yet unidentified ovarian factor that acts on the pituitary to attenuate the pre-ovulatory LH surge. In a previous study, GnSAF bioactivity was proposed ... -
Serum Amyloid Alpha in Parapneumonic Effusions
(2011)Study objectives. To assess serum amyloid alpha (SAA) pleural fluid levels in parapneumonic effusion (PPE) and to investigate SAA diagnostic performance in PPE diagnosis and outcome. Methods. We studied prospectively 57 ... -
Surface wettability effects on flow in rough wall nanochannels
(2012)The effect of rough-wall/fluid interaction on flow in nanochannels is investigated by NEMD. Hydrophobic and hydrophilic surfaces are studied for walls with nearly atomic-size rectangular protrusions and cavities. Our NEMD ... -
Three-dimensional stability of free convection vortices in the presence of a magnetic field
