7. Human continuous glucose monitors for measurement of glucose in dairy cows

Author

Byrd, M.K.H., Arneson, A.G., Soffa, D.R., Stewart, J.W., and Rhoads, M.L.

Abstract

Summary:The purpose of this study was to determine whether interstitial glucose measurements collected by sensors designed for humans could replace blood-based glucose measurements in dairy cows. Lactating Holstein cows (n = 21) were fit with indwelling jugular catheters, as well as FreeStyle Libre (FSL; Abbott) or Dexcom G6 (DexCom Inc.) interstitial glucose monitors secured either near their ears or on their upper rear legs. Functional longevity of the sensors was greatest for those sensors secured near the ear. Blood glucose concentrations were most closely correlated with interstitial measurements from the FSL ear (r = 0.82) and the Dexcom G6 ear (r = 0.71), but accuracy was low. Both ear sensors detected an increase in glucose concentrations following a bolus dose but neither produced results exactly matching the blood glucose measurements. The results of this work indicate that both sensors can detect large changes in glucose, but neither is currently capable of replacing blood-based glucose measurements in dairy cows.

21. Pyrimethamine in the myeloproliferative disorders: a forgotten treatment?

Author

BOWCOCK, S.J., LINCH, D.C., MACHIN, S.J., and STEWART, J.W.

Abstract

SummaryEight patients with myeloproliferative disorders, five with polycythaemia rubra vera (PRV) and three with essential thrombocythaemia (ET), have been treated with the anti‐folate drug Pyrimethamine for periods ranging from 1 to 24 years. In PRV this treatment was comparable in efficacy to that achieved with Busulphan or radioactive phosphorus, but required more frequent supervision. One patient was controlled on Pyrimethamine, having failed on conventional treatment. The major side effect was thrombocytopenia which was rapidly reversible on stopping the drug. In ET, Pyrimethamine produced satisfactory control of the platelet count and thrombocytopenia did not arise. No neurological sequelae were encountered. One patient developed a non‐Hodgkin's lymphoma of the gut, but there were no other cases of secondary malignancy. Pyrimethamine may still have a role in the treatment of selected cases of myeloproliferative disorders.

23. Form-Factor Ratio GE(n)/GE(p) at Low Momentum Transfers

Author

Bumiller, F.A., Buskirk, F.R., Stewart, J.W., Dally, E.B., and Physics

Abstract

Measurements of the ratio of the deuteron to proton electric form factors, GE(d)/GE(p), were made from elastic electron-deuteron scattering to a precision of approximately 1% for the range of momentum transfers ...

Abstract

Abstract: Y3Fe5O12 (YIG) crystal has many attractive characteristics, such as low dielectric loss, narrow resonance linewidth in microwave region and also possesses a good saturated magnetization value. Composite technology in general sets out to combine materials in such a way that the properties of the composite are the optimum for a particular application. The different materials work together to give a composite of unique properties. In this work, we present the preparation procedure (obtaining) of the GdIG X :YIG1− X ferrimagnetic ceramic matrix composite by mechanical alloying and calcinations. Besides that, we study its properties by X-ray powder diffraction, infrared, Micro-Raman, 57Fe Mössbauer spectroscopy and hysteresis loop measurements. [Copyright &y& Elsevier]
