The inhibition of S-aden.osylmethionine: Δ²⁴-sterol methyltransferase
(EC 2.1.1.41) activity by endogenous cellular components has
been studied in vitro. The principal inhibitors were Na⁺ and K⁺; Cs⁺,
NH₄⁺ and Li⁺ were also shown to inhibit the reaction. The inhibition
by potassium cation has been studied, and we have found that energy...
Research was carried out to determine the influence of increasing
the percentage base saturation of the soil on the yield of
the commercial strawberry. It was found that the effect of increasing
the bases in the soils was directly related to the original
percentage base saturation. When this original value...
”Until relatively recently, mankind was not aware that there was a separable binocular depth sense. Through the ages, people like Euclid and Leonardo understood that we see different images of the world with each eye. But it was Wheatstone who in 1838 explained to the world, with his stereoscope and...
As ornamental container nurseries face diminishing water allocations, many are looking to automated irrigation solutions to increase their water application efficiency. This thesis presents the findings of a study conducted at a commercial container nursery to determine 1) whether a capacitance or load cell sensor was better suited for monitoring...
A digoxigenin-labeled nonradioactive detection system was used
to screen a zebrafish cDNA library for p53-like and ras-like genes.
One clone was isolated and identified as an incomplete p53-like
gene. The insert size of this clone is 1777 bp, which encodes part of
evolutionarily conserved region II and all of regions...
The question of how the presence of nucleosomal
packing of DNA modifies carcinogen interaction at
specific sites cannot be answered by studies on whole
chromatin or bulk nucleosomes because of the
heterogeneity of DNA sequences in the particles. This
problem was circumvented by constructing nucleosomes that
are homogenous in DNA-histone...
Dimethylbenz (a) anthracene (EMBA), a carcinogen that requires
metabolic activation to produce active metabolites capable of
binding to DNA, has been studied in the trout and other fish.
Polycyclic aromatic hydrocarbons (PAH) are of importance as they
are ubiquitous in the environment and their carcinogenic effects
in fish from contaminated...
