Mountain pine beetles,Dendroctonus ponderosae Hopkins, and California five-spined ips,Ips paraconfusus Lanier, were reared axenically from surface-sterilized eggs on aseptic pine phloem. After 24 hr in host logs, axenip femaleD. ponderosae and maleI. paraconfusus produced the aggregation pheromones,trans-verbenol (D. ponderosae), and ipsenol and ipsdienol(More)
After peroral administration of sunflower oil to chick old 14 to 23 days, the rise and passage of chylomicrons were studied electronoptically in the enterocytes of the small intestine. Enterocytes resynthetize the absorbed monoglycerides and fatty acids into neutral fat in the profiles of smooth endoplasmic reticulum and in multivesicular corpuscles in the(More)
The ultraviolet circular dichroism (CD) spectra of commercial low-molecular-weight heparins, heparinoids and other anticoagulant preparations have been recorded between 180 and 260 nm. Principal component analysis of the spectra allowed their differentiation into a number of groups related to the means of their production reflecting the structural changes(More)
