BACKGROUND: It is well known that human milk oligosaccharides play an important role as prebiotics, anti-inflammatory, and anti-infective agents. In the last few years, several studies have been performed using specific oligosaccharides, such as 2'-fucosyllactose and 6'-sialylactose, to evaluate their biological functions. OBJECTIVES: The aim of the present study is to evaluate the anti-adhesive effect of the above oligosaccharides on Escherichia coli and Salmonella fyris...

BACKGROUND: Transpulmonary thermodilution (TPTD) is used to derive cardiac output CO, global end-diastolic volume GEDV and extravascular lung water EVLW. To facilitate interpretation of these data, several ratios have been developed, including pulmonary vascular permeability index (defined as EVLW/(0.25*GEDV)) and global ejection fraction ((4*stroke volume)/GEDV). PVPI and GEF have been associated to the aetiology of pulmonary oedema and systolic cardiac function, respectively. Several studies demonstrated that the use of femoral venous access results in a marked overestimation of GEDV...

A thorough QT/QTc study in healthy white Caucasian subjects demonstrated that rupatadine has no proarrhythmic potential and raised no cardiac safety concerns. The present phase 1 study aimed to confirm the cardiac safety of rupatadine in healthy Japanese subjects. In this randomized, double-blind, placebo-controlled study, 27 healthy Japanese subjects were administered single and multiple escalating rupatadine doses of 10, 20, and 40 mg or placebo. Triplicate electrocardiogram (ECG) recordings were performed on days -1, 1, and 5 at several points, and time-matched pharmacokinetic samples were also collected...

Quantification of the uncertainty in constitutive model predictions describing arterial wall mechanics is vital towards non-invasive assessment of vascular drug therapies. Therefore, we perform uncertainty quantification to determine uncertainty in mechanical characteristics describing the vessel wall response upon loading. Furthermore, a global variance-based sensitivity analysis is performed to pinpoint measurements that are most rewarding to be measured more precisely. We used previously published carotid diameter-pressure and intima-media thickness (IMT) data (measured in triplicate), and Holzapfel-Gasser-Ogden models...

BACKGROUND: The gold standard method for assessing the QTcF (QT corrected for heart rate by Fridericia's cube root formula) interval is the "QTcF semiautomated triplicate averaging method" (TAM), which consists of measuring three QTcF values semiautomatically, for each 10-second sequence of a triplicate electrocardiogram set, and averaging them to get a global and unique QTcF value. Thus, TAM is time consuming. We have developed a new method, namely the "QTcF semiautomated triplicate concatenation method" (TCM), which consists of concatenating the three 10-second sequences of the triplicate electrocardiogram set as if they were a single 30-second electrocardiogram, and measuring QTcF only once for the triplicate electrocardiogram set...

Coil satellite centrifuge (CSC) produces the complex satellite motion consisting of the triplicate rotation of the coiled column around three axes including the sun axis (the angular velocity, ω1 ), the planet axis (ω2 ) and the satellite axis (the central axis of the column) (ω3 ) according to the following formula: ω1 =ω2 +ω3 . Improved peak resolution in the separation of 4-methylumbelliferyl sugar derivatives was achieved using the conventional multilayer coiled columns with ethyl acetate/1-butanol/water (3: 2: 5, v/v) for the lower mobile phase at the combination of the rotation speeds (ω1 , ω2 , ω3 )=(300, 150, 150rpm), and (1:4:5, v/v) for the upper mobile phase at (300:100:200rpm)...

BACKGROUND: Enteral nutrition (EN) misconnections have been identified as a serious and potential deadly problem. An international effort led by EN industry leaders has developed a small-bore enteral connector (ENFit) that in theory will reduce the frequency of misconnections. Despite the potential benefit of preventing misconnections, the full impact of adoption of the ENFit connector is unknown. To assess the impact of transitioning to ENFit on our home EN (HEN) patients, the current study evaluated gravity feeding comparing 2 proposed small-bore connectors to the legacy (current connector) using various commercial formulas...

Due to its anti-inflammatory and immunosuppressive potential, Nitric oxide (NO), a gaseous radical, is of special importance during graft-versus-host diseases (GVHD) and feoto-maternal tolerance. NO is a major mediator of murine mesenchymal stromal cells (MSCs)-immunosuppressive capacity. In this data article, we characterized NO production by human bone marrow-derived MSCs (hBMSCs). MSCs, isolated from healthy donors (n=5), were defined according to the International Society for cellular Therapy (ISCT) guidelines...

Global ejection fraction (GEF) and cardiac function index (CFI) are transpulmonary thermodilution (TPTD)-derived indices of the systolic function. Their validity relies on an accurate determination of the global end-diastolic volume (GEDV). Due to an overestimation of GEDV using a femoral central venous catheter (CVC) a correction formula for indexed GEDV (GEDVI) has been implemented in the latest PiCCO™-algorithm. However, a recent study demonstrated that correction for femoral CVC does not pertain to pulmonary vascular permeability index PVPI, which is calculated of extravascular lung water EVLW and GEDV...

An important priority of poultry producers is to guarantee animal welfare during animal production; however, broilers are exposed to unavoidable chronic stress (also known as allostasis) when they are captured, caged, and transported to the processing plant. This antemortem management causes allostatic load, animal injuries, and poor carcass quality. The aim of the present study was to evaluate the effects of an allostatic modulator (AM) on antemortem stress by measuring the appearance and microbiological quality of broiler carcasses...

A new high-speed counter-current chromatograph, named coil satellite centrifuge (CSC), was designed and fabricated in our laboratory. The CSC apparatus produces the satellite motion such that the coiled column simultaneously rotates around the sun axis (the angular velocity, ω1), the planet axis (ω2) and the satellite axis (the central axis of the column) (ω3). In order to achieve this triplicate rotary motion without twisting of the flow tube, the rotation of each axis was determined by the following formula: ω1=ω2+ω3...

Publications on the health effects of vitamin D (25(OH) D) had almost triplicate in the last 10years, not only for its known "calcemic effects" (calcium, phosphor, PTH), but for the more recent findings on its "non-calcemic effects" (all-cause and cardiovascular mortality, and relation with certain types of cancer). Part of these publications deal with the definition of what is a "normal" circulating level of 25(OH) D that may distinguish between health and disease. The literature also deals with seasonal variations of vitamin D, showing levels that rise in summer and fall in winter and with DBP phenotypes and geographical location that affect seasonality of 25(OH) D measurements...
