Objective: To standardize an ELISA protocol to quantify total immunoglobulin A(IgA)from different biological ***: Two independent experiments were conducted. In Experiment 1, total IgA levels were quantified from the lachrymal fluid, tracheal swab, and cloacal swab at various time points from Days 30 to 89 in white Leghorn chickens. Experiment 2 was conducted to evaluate the effect of 50 or 500 ppb of aflatoxin b1(AFb1) on total IgA quantified in samples from the lachrymal fluid, tracheal swab, gut content and cloacal swab in broiler chickens at 21 days of ***: Lachrymal fluid contained the highest level of IgA; however, the sampling procedure was time consuming and stressful to the bird, and the sample volume depends largely on the size of the chicken. Cloacal swabs also contained a high concentration of IgA; this sampling procedure was faster than lachrymal fluid sampling and was not affected by the age of the bird. Tracheal sampling was more difficult than cloacal sampling; the age of the bird limited the sampling, and the IgA concentration was the lowest detected at all sampling ages. 500 ppb of AFb1 significantly reduced total IgA concentration in the gut content compared with control or 50 ppb of AFb1 treated ***, a significant reduction in total IgA was also observed in those chickens that received 50 ppb of AFb1 in gut rinse when compared with cloacal ***: The results of this study suggest that cloacal swab is an easy and reliable way to evaluate mucosal IgA concentration in both Leghorn and broiler chickens.

Rapid, Non-Destructive, Textile Classification Using SIMCA on Diffuse Near-Infrared Reflectance Spectra

引用

Journal of Modern Physics 2015年第6期6卷 711-718页

作者： Christopher b. Davis Kenneth W. busch dennis H. Rabbe Marianna A. busch Judith R. Lusk Department of Chemistry and biochemistry Baylor University Waco USA Department of Family and Consumer Sciences Baylor University Waco USA

Soft independent modeling of class analogy (SIMCA) was successful in classifying a large library of 758 commercially available, non-blended samples of acetate, cotton, polyester, rayon, silk and wool 89% - 98% of the time at the 95% confidence level (p = 0.05 significance level). In the present study, cotton and silk had a 62% and 24% chance, respectively, of being classified with their own group and also with rayon. SIMCA correctly identified a counterfeit “silk” sample as polyester. When coupled with diffuse NIR reflectance spectroscopy and a large sample library, SIMCA shows considerable promise as a quick, non-destructive, multivariate method for fiber identification. A major advantage is simplicity. No sample pretreatment of any kind was required, and no adjust-ments were made for fiber origin, manufacturing process residues, topical finishes, weave pattern, or dye content. Increasing the sample library should make the models more robust and improve identification rates over those reported in this paper.

Validation of a discrete element model using magnetic resonance measurements

引用

Particuology 2009年第4期7卷 297-306页

作者： Christoph R.Müller Stuart A.Scott Daniel J.Holland belinda C.Clarke Andrew J.Sederman John S.dennis Lynn F.Gladden Department of Chemical Engineering and biotechnology University of CambridgePembroke StreetCambridge CB2 3RAUnited Kingdom

The discrete element model （DEM） is a very promising modelling strategy for two-phase granular systems. However, owing to a lack of experimental measurements, validation of numerical simulations of two-phase granular systems is still an important issue. In this study, a small two-dimensional gas- fluidized bed was simulated using a discrete element model. The dimensions of the simulated bed were 44mm × 10mm × 120 mm and the fluidized particles had a diameter dp = 1.2 mm and density ρp = 1000 kg/m^3. The comparison between DEM simulations and experiments are performed on the basis of time-averaged voidage maps. The drag-law of beetstra et al. [beetstra, R., van der Hoef, M.A., ＆ Kuipers,J. A. M. （2007b）. Drag force of intermediate Reynolds number flow past mono- and bidispersed arrays of spheres. AIChE Journal, 53,489-501 ] seems to give the best results. The simulations are fairly insensitive to the coefficient of restitution and the coefficient of friction as long as some route of energy dissipation during particle-particle and particle-wall contact is provided. Changing the boundary condition of the gas phase at the side-walls from zero-slip to full-slip does not affect the simulation results. Care is to be taken that the cell sizes are chosen so that a reasonable number of particles can be found in a fluid cell.

Spatially engineered nonlinearity in resonant metasurfaces

Photonics Research 2023年第2期11卷 252-259页

Spatial engineering of the nonlinear susceptibility χ^((2)) in resonant metasurfaces offers a new degree of freedom in the design of the far-field response of second-harmonic generation(SHG). We demonstrate this by applying electric field poling to lithium niobate(LN) thin films, which inverts the spontaneous polarization and thus the sign of χ^((2)). Metasurfaces fabricated in periodically poled LN films reveal the distinct influence of theχ^((2))-patterning on the spatial distribution of the second harmonic. This work is a first step toward far-field engineering of SHG in metasurfaces with electric field poling.

Connective Tissue Energy Loss Comparison between Joints with and without Hypermobility

引用

Journal of biomedical Science and Engineering 2017年第5期10卷 18-27页

作者： Stephen A. Tatarkov Angela C. Tesny brittany M. Lauck Louis A. Diberardino III Hui Shen Mechanical Engineering Ohio Northern University Ada OH USA

Joint hypermobility syndrome is a condition in which a joint can move effortlessly beyond the normal limit of motion expected for that joint. This syndrome is affected by some factors including gender and tends to be inherited. It may cause some symptoms such as pain in an individual’s synovial joints. The objective of the current study was to compare the energy loss of connective tissues between joints with and without hypermobility. A differential equation model, namely the Kelvin-Voigt model, was used for the energy loss analysis. The results show the difference in energy loss for the tissues attached to joints with and without joint hypermobility. As the stiffness of the connective tissue decreases, the energy loss increases. Muscle activity about the ankle was measured via electromyography during simple functional tasks, and the recorded data were used to correlate with the theoretical analysis of the energy loss. The result would shed light on the pathology analysis of the symptoms such as the cause of pain.

Influence of Acetaminophen on Pharmacokinetics and Pharmacodynamics of Midazolam in Healthy Volunteers

引用

Open Journal of Anesthesiology 2015年第6期5卷 116-121页

作者： dennis Feierman Tunga Suresh Murali Pagala Jeffery Silverstein Department of Anesthesiology Maimonides Medical Center Brooklyn USA Department of Anesthesiology Mount Sinai School of Medicine New York USA

background: Midazolam and acetaminophen are often co-administered in anesthesia practice. both are metabolized by CYP 3A4 enzyme in the liver, and hence compete for the enzyme sites. This might lead to reduced metabolic breakdown and enhanced pharmacodynamic effects of midazolam in the presence of acetaminophen. Methods: The present study was undertaken to test this hypothesis. After IRb approval from Mount Sinai Medical Center, 15 healthy volunteers were used for 2 tests. For the first test, they were randomly assigned to receive oral doses of either midazolam 0.3 mg/kg in cherry syrup (Protocol A), or midazolam 0.3 mg/kg plus cherry flavored acetaminophen 15 mg/kg (Protocol b). At set intervals from 0 to 480 min, the blood levels of midazolam and the subjects pulse rate, mean arterial pressure, respiratory rate, bIS index, and OAA/S scores were determined. After 2 weeks, the same subjects underwent the second test;they received the other medication protocol. Results: Acetaminophen slightly, but not significantly, increased the half life of blood midazolam, and the depressive effects of midazolam on the clinical signs of the subjects. Conclusion: These results lead us to conclude that there is no need to reduce the doses of midazolam when used in combination with acetaminophen.
