Nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) are the two most commonly used analytical tools in metabolomics, and their complementary nature makes the combination particularly attractive. A combined analytical approach can improve the potential for providing reliable methods to detect metabolic profile alterations in biofluids or tissues caused by disease, toxicity, ...

In this paper we ask three questions. Do PLS path estimates compensate for measurement error? Do they capitalize on chance? And is PLS able to more accurately weight measurement indicators so as to make path estimations more accurate? The evidence is quite convincing that PLS path estimates do have all three of these characteristics. Our analysis suggests, however, that measurement error has by...

The ultimate goal of any prescribed medical therapy is to achieve desired outcomes for patients. However, patient non-compliance has long been a major problem detrimental to patients’ health and thus is a concern of all healthcare providers. Patient trust in doctors and patient-doctor communication have been identified as critical factors influencing patient compliance. Nevertheless, little is ...

INTRODUCTION The incidence of oral sinus communications (OSC) following the extraction of an upper third molar remains uncertain. OBJECTIVES The purpose of this study was to determine the incidence of OSC following the extraction of 389 consecutive upper third molars during 2003 in the Master of Oral Surgery and Orofacial Implantology (Barcelona University, Spain). PATIENTS AND METHOD Diffe...

There have been reports of strong correlations between poor prognosis in various cancers and concomitant expression of urokinase-type plasminogen activator (uPA) and its surface receptor (uPAR). We and others have previously shown that the uPA system plays a significant role in a subset of head and neck squamous cell carcinoma. In the present study, we found that uPAR is required for invasion a...

A facile solvothermal method to synthesize aluminum-doped ceria-zirconia (Ce0.5Zr0.5-xAlxO2-x/2, x = 0.1 to 0.4) solid solutions was carried out using Ce(NH4)2(NO3)6, Zr(NO3)3·2H2O Al(NO3)3·9H2O, and NH4OH as the starting materials at 200°C for 24 h. The obtained solid solutions from the solvothermal reaction were calcined at 1,000°C for 20 h in air atmosphere to evaluate the thermal stability....

The aim of this study was to identify the optimal and superior type of natural calcium for replacing phosphate in cooked ground pork products. To achieve this, 0.5% eggshell calcium (ESC), oyster shell calcium (OSC), marine algae calcium (MAC), or milk calcium (MC) was added to ground pork meat products. The effect of this substitution was studied by comparing the substituted products with prod...

A largely overlooked side result in most studies of morphological priming is a consistent main effect of semantic transparency across priming conditions. That is, participants are faster at recognizing stems from transparent sets (e.g., farm) in comparison to stems from opaque sets (e.g., fruit), regardless of the preceding primes. This suggests that semantic transparency may be also consistent...

BACKGROUND Acute pancreatitis (AP) is a common inflammatory disease of the pancreas accompanied by serious metabolic disturbances. Nevertheless, the specific metabolic process of this disease is still unclear. Characterization of the metabolome may help identify biomarkers for AP. To identify potential biomarkers, this study therefore investigated the 1H-nuclear magnetic resonance (NMR)-based m...

For SMEs, responsiveness to changes is a critical survival capability. Practitioners believe that IT infrastructure flexibility contributes to responsiveness, yet empirical evidence is sparse. The purpose of this research is to empirically test the relationship between IT infrastructure flexibility, which is measured on four dimensions, and IT responsiveness. Two research questions are answered...
