Androgens produced by stimulating mouse testis with gonadotropic hormones cause a rise in renal beta-glucuronidase but not an increase in acid or alkaline phosphatase. All subcellular components increase in beta-glucuronidase activity, with a relatively greater increment in particulate enzyme as compared with that free in the cytoplasm (non-sedimentable). A small percentage of recovered beta-gl...

Our purpose was to compare HDL subpopulations, as determined by nondenaturing two-dimensional gel electrophoresis followed by immunoblotting for apolipoprotein A-I (apoA-I), apoA-II, apoA-IV, apoCs, and apoE in heterozygous, compound heterozygous, and homozygous subjects for cholesteryl ester transfer protein (CETP) deficiency and controls. Heterozygotes, compound heterozygotes, and homozygotes...

In this paper we analyze metastability and nucleation in the context of a local version Kawasaki dynamics for two-dimensional strongly anisotropic Ising lattice gas at very low temperature. Let $\Lambda\subset\mathbb{Z}^2$ be finite box. Particles perform simple exclusion on $\Lambda$, but when they occupy neighboring sites feel binding energy $-U_1<0$ horizontal direction $-U_2<0$ vertical one...

The growing need to quantitate alpha emitting radionuclides in the environment and in nuclear fuel processing and disposal has resulted in dramatic increases in gross alpha/gross beta measurements. In fact, gross alpha/gross beta counting has become the most widely used method of monitoring for the presence of radioactivity. Much of the interest is due to the need to address safety, regulatory ...

Abstract While radioguided surgery (RGS) traditionally relied on detecting gamma rays, direct detection of beta particles could facilitate the tumour margins intraoperatively by reducing radiation noise emanating from distant organs, thereby improving signal-to-noise ratio imaging technique. In addition, most existing detectors do not offer surface sensing or capabilities. Therefore, we explore...

The influence of zeolite support materials and their impact on CH4 oxidation activity was studied utilizing Pd supported H-beta H-SSZ-13. A correlation between activity, Si/Al ratio (SAR), the type framework, reduction-oxidation behaviour, species present found by combining catalytic measurements with a variety characterization methods (operando XAS, NH3-TPD, SAXS, STEM NaCl titration). Operand...

Radiation is the emission or transmission of energy as waves particles through space a material medium which able to penetrate various materials and often categorized either ionizing non-ionizing depending on radiated particles. processing can be defined exposure with high radiation change their physical, chemical, biological characteristics, increase usefulness, safety purpose, reduce harmful ...

The plasma lipoproteins and "particles"' fall into four major groups. As defined by paper electrophoresis (3) these are the beta, alpha, and pre-beta lipoproteins, and chylomicrons. The latter two are rich in glyceride and very low in density (< 1.006, Sf > 20). It is now common to reserve the term chylomicrons for the relatively large particles that arise in the gut from exogenous or ingested ...
