We study the feasibility of leveraging the sensors embedded on mobile devices to enable a user authentication mechanism that is easy for users to perform, but hard for attackers to bypass. The proposed approach lies on the fact that users perform gestures in a unique way that depends on how they hold the phone, and on their hand’s geometry, size, and flexibility. Based on this observation, we i...

Nanomaterials are acclaimed for their novel properties, for which broad new uses are being discovered with increasing frequency. It is obvious that, as the properties change, unwanted properties (toxicity) are to be expected as well. today’s toxicology, however, is already overwhelmed with the challenge of addressing new chemicals, not to mention the enormous number of old chemicals never prope...

Lactobacillus curvatus LTH 1174, a strain originating in fermented sausage, produces the antilisterial bacteriocin curvacin A. Its biokinetics of cell growth and bacteriocin production as a function of various concentrations of salt (sodium chloride) were investigated in vitro during laboratory fermentations using modified MRS medium. A model was set up to describe the effects of different NaCl...

Within the Predict-IV FP7 project a strategy for measurement of in vitro biokinetics was developed, requiring the characterization of the cellular model used, especially regarding biotransformation, which frequently depends on cytochrome P450 (CYP) activity. The extrahepatic in situ CYP-mediated metabolism is especially relevant in target organ toxicity. In this study, the constitutive mRNA lev...

Liver-bile secretion directly influences the content of plutonium in feces. To assess the reliability of plutonium metabolic models and to improve the accuracy of interpreting plutonium fecal data, we developed a compartmental model that simulates the metabolism of plutonium in humans. With this model, we can describe the transport of plutonium contaminants in the systemic organs and tissues of...

CONTEXT Once inhaled, nanoparticles (NP) deposit on the lung surface and have first contact with the epithelial lung lining fluid (ELF) rich in proteins, which may bind to NP. OBJECTIVE In this study, we investigate the parameters that influence the binding between NP and proteins. MATERIALS AND METHODS We used the proteins albumin, transferrin (TF), and apolipoprotein A-1 (all known as pro...

BACKGROUND Revascularization therapy relieves myocardial ischemia, but can also result in ischemia-reperfusion injury caused by oxidative stress. However, the biokinetics of oxidative stress after myocardial ischemia-reperfusion are uncertain. This study aimed to evaluate the dynamics of oxidative stress after off-pump coronary artery bypass grafting (OPCAB) by measuring urinary biopyrrin level...

The use of live animal gamma radioisotope tracer techniques in the field of ecotoxicology allows laboratory studies to accurately monitor contaminant biokinetics in real time for an individual organism. However, methods used in published studies for aquatic organisms are rarely described in sufficient detail to allow for study replication or an assessment of the errors associated with live anim...

We announce the annual meeting of Korean Society of Exercise Rehabilitation celebrated our tenth birthday this month. To this date, we have covered different genres of translational research, such as exercise neuroscience, rehabilitation program and physical practice, and also written about health promoting lifecycle, revitalization movement, and clinical sport medicine. We have done our best t...
