The compound (1-[p-@-diethy aminoethoxy)-phenyl]-l-(ptolyl)-2-(p-chlorophenyl)ethanol), known by its trade name as MER-29,’ has been shown by Blohm et al. to cause a depression in serum and tissue cholesterol and to inhibit cholesterol biosynthesis in animals (1,2). These authors found that the incorporation of I-C14-acetate into the total nonsaponifiable lipid fraction of rat liver and into th...

Saccharomyces cerevisiae normally will not take up sterols from the environment under aerobic conditions. A specific mutant, upc2-1, of the predicted transcriptional activator UPC2 (YDR213w) has been recognized as a strain that allows a high level of aerobic sterol uptake. Another predicted transcriptional activator, the YLR228c gene product, is highly homologous to Upc2p. In fact, at the carbo...

in this study, the vertical, transverse and oblique diameters of the spinal cord segments (c1, c6, c12, c18, t1, t4, l1, l4, l6 and l8) and the ratio of gray matter to white matter in chick (l month) and adult (18 months) male ostriches, each group consisted of 3 animals, were measured with standard micrometric method using 6 μm thick sections by light microscope. with advancement of age, the r...

An atypical variant of Candida tropicalis was recovered from multiple specimens from a patient who had been a recipient of a bone marrow transplant. This yeast variant showed atypical morphology on corn meal agar distinguishable from typical isolates of C. tropicalis by the production of clusters of blastospores. Isolates of the variant produced acid, but no gas, from maltose and sucrose in fer...

the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...

background: volume estimation of brain is important for many neurological applications. it is necessary in measuring brain growth and changes in brain in normal/abnormal patients. thus, accurate brain volume measurement is very important. magnetic resonance imaging (mri) is the method of choice for volume quantification due to excellent levels of image resolution and between-tissue contrast. st...

We have briefly proposed (1) the general theory that “acetate-derived” aromatic metabolites arise ana.logously to fatty acids, by repeated condensation of malonyl coenzyme A units with an acyl coenzyme A “starter,” citing in support our own work on the 6-methylsalicylic acid of Penicillium urticae and the prior report of Bentley and Keil (2) on penicillic acid. A number of subsequent publicatio...

Autotrophically grown cells of Chlorella pyrenoidosa (211-8b) were starved 3 to 4 days in darkness, flashes of blue light, or flashes of red light. The blue flashes were sufficient to maintain the maximal rate of light-stimulated oxygen uptake during short term experiments. However, after 24 hours, the respiration rate in red flashes was equal to, or greater than, the rate in blue flashes. Star...

l-Menthone of peppermint leaves is reduced to d-neomenthol which is glucosylated and transported to the rhizome, whereupon the beta-d-glucoside is hydrolyzed, the aglycone oxidized back to l-menthone, and this ketone converted to l-3,4-menthone lactone. l-[G-(3)H]-3,4-Menthone lactone and its labeled progenitors, when incubated with excised mint rhizomes, gave rise to nonvolatile lipids as well...
