A colorimetric method for the determination of deoxyribonucleic acid in adipose tissue.
(Analyst, 1975)A method is described for measuring the deoxyribonucleic acid (DNA) content of small samples of adipose tissue or free fat cells. Lipids and acid-soluble nucleotides are first removed by extraction with a cold diethyl ... -
Zonal rotor study of the subcellular distribution of acyl-CoA synthetases, carnitine acyl transferases and phosphatidate phosphatase in the guinea-pig small intestine.
(European Journal of Cell Biology, 1979)Homogenates made from the mucosa of the guinea pig small intestine were fractionated in a zonal rotor by rate and isopycnic centrifugation in sucrose gradients. Density perturbation of endoplasmic reticulum vesicles was ... -
Strategies of subcellular fractionation suitable for analysis of peroxisomes and microperoxisomes of animal tissues.
(International Journal of Biochemistry, 1983)Strategies of subcellular fractionation are reviewed from the perspective of their utility in the analysis of peroxisomes. The considerable potential inherant in the method of rate dependent banding In zonal rotors is ... -
Coronary heart disease - dietary lipids or refined carbohydrates?
(Medical Hypotheses, 1983)The epidemiological evidence associating dietary lipids, refined carbohydrates and coronary heart disease (CHD) is evaluated. Population studies often show a high correlation between dietary lipid and heart disease ... -
Refined carbohydrates - a cause of suboptimal nutrient intake.
(Medical Hypotheses, 1983)During the refining of carbohydrate foods there is a sharp drop in the concentration of dietary fiber and of various vitamins and minerals. Estimates were made of the effect of refining on the total diet intake of ... -
Intestinal peroxisomes of goldfish (Carrassius auratus) - examination for hydrolase, dehydrogenase and carnitine acetyltransferase activities.
(Comparative Biochemistry and Physiology, 1979)1. Rate sedimentation and isopycnic centrifugation were used to analyse the subcellular sites of enzymes in homogenates of goldfish intestinal mucosa. 2. The results allowed the following allocations to be made: carnitine ... -
Subcellular localization of monoglyceride acyltransferase, xanthine oxidation, NADP: isocitrate dehydrogenase and alkaline phosphatase in the mucosa of the guinea-pig small intestine.
(Comparative Biochemistry and Physiology, 1980)1. Rate dependent and isopycnic banding in a zonal rotor were used to analyse the subcellular sites of enzymes in homogenates of guinea-pig small intestinal mucosa. 2, The results demonstrate the following localizations: ... -
Simplicity - the key to fruitful medical research
(Medical Hypotheses, 1985)Medical research is here divided -into two broad categories. The great majority of research is "complex" and includes all studies of intricate body mechanisms. A minority of research is "simple" and deals mainly ... -
High fat diets and mouse colon mucosal membranes: a centrifugation study.
(Cancer Letters, 1983)Female Swiss mice were fed on a control diet (laboratory chow, 6% fat) or high fat diets (laboratory chow with added fat, principally corn oil, to produce a fat content of 16% or 23%). Homogenate of colon mucosa ... -
Time Evolution of the Substorm Current Wedge from Ground and Space-based Magnetic Fields
(2007-12-19)Over the past several years, intensive efforts have resulted in a significant improvement in the ground instrumentation for auroral studies in North America. A major part of this is due to the THEMIS ground program, both ... -

Progress on Low-Cost Pulse-Counting Magnetometers for Geomagnetic Studies
(2007-11-28)"what the world needs now is a good $500 magnetometer" -
Inner solar system dynamical analogs of plutinos
(2007-11-20)By studying orbits of asteroids potentially in 3:2 exterior mean motion resonance with Earth, Venus, and Mars, we have found plutino analogs. We identify at least 27 objects in the inner solar system dynamically protected ... -
Pulp and Paper Mill References

Two new species of Sabacon harvestmen, with descriptions of the females of Sabacon astoriensis Shear and Sabacon sheari Cokendolpher, from Western North America. (Arachnida, Opiliones, Sabaconidae)
(Entomological Society of Alberta meeting, Athabasca, 2003)Two new species of Sabaconidae (Ischyropsalidoidea) are described: Sabacon # 1 from central Alberta and British Columbia and Sabacon # 2 from Oregon. Descriptions of the females of Sabacon astoriensis Shear 1975, from ... -
