Aedes melanimon in Saskatchewan
(Mosquito News, 1968) -
The odoriferous glands of some Palpatores Phalangida (Opiliones) (Arachnida)
(The University of Saskatchewan, 1971)The odoriferous glands of especially Phalangium opilio and to a lesser extent Opiliones parietinus, Odiellus pictus, Homolophus biceps, Leiobunum calcar and L.. vittatum were investigated by: external examination; dissection; ... -
Investigations into the effects of cyclical rhythm and hormonal contraception on serum fat-mobilizing activity, glycerol, cholesterol and blood glucose.
(Acta Endocrinology, 1974)The effects were investigated of cyclical rhythm and hormonal contraception on serum fat-mobilizing activity, glycerol, cholesterol and whole blood glucose during 2 menstrual cycles in a group of normally menstruating young ... -
Platybunus triangularis and Paroligolophus agrestis: two phalangids introduced to North America (Arachnida, Opiliones)
(Journal of Arachnology, 1975) -
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 ... -
International Survey Data
(Trends in Biochemistry Science, 1976) -
Zonal rotor analysis of the subcellular localization of B-glycero-phosphate dehydrogenase, 1-naphthyl palmitate and 2-napthyl laurate hydrolases in the mucosa of the guinea-pig small intestine.
(Histochemistry Journal, 1976)Whole homogenate of guinea-pig small intestine mucosa was analysed by centrifugation in a zonal rotor. The results indicate that FAD-linked a-glycerophosphate dehydrogenase is localized in the mitochondria and that ... -
Selective predation in a polyphagous invertebrate predator, Pardosa vancouveri (Arachnida, Araneae)
(Simon Fraser University, 1979)Selective predation (i.e., non-random feeding) was studied in a laboratory system that allowed individual lycosid spiders, Pardosa vancouveri. to feed on prey populations consisting of one or two kinds of insects. Various ... -
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 ... -
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: ... -
Selective predation in a euryphagous invertebrate predator, Pardosa vancouveri (Arachnida, Araneae)
(Canadian Entomologist, 1982)Selective predation (i.e., non-random feeding) was studied in a laboratory system that allowed individual lycosid spiders, Pardosa vancouveri, to feed on prey populations consisting of one or two kinds of insects. Various ... -
Laboratory work in distance education
(Distance Education, 1982)A major concern in distance education is how to overcome the problems associated with laboratory components of courses. In this paper we review the general importance of laboratory work for students, summarise the ... -
A blind Homolophus biceps (Arachnida, Opiliones)
(Entomological News, 1983)Scanning electron microscopy of a harvestman, Homolophus biceps. that lacked both eyes and ocular tubercle revealed no indication of external damage or healing. Internally, light microscope sections showed no evidence ... -
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 ... -
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 ... -
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 ... -
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 ... -
Relating feeding rates to sex and size in six species of grasshoppers (Orthoptera: Acrididae).
(Canadian Entomologist, 1984)Nymphs and adults of both sexes of six species of grasshoppers. Camnula pellucida, Dissosleira carolina, Melanoplus infantilis. M. sanguinipes, M. packardii and M. bivillalus, were fed wheat seedlings to determine daily ... -
