Oestrogen Sulfotransferase: Molecular Cloning and Sequencing of cDNA for the Bovine Placental EnzymeCSIRO Publishing - Tập 41 Số 4 - Trang 507 - 1988
Allan R. Nash, Wendy K. Glenn, S. S. Moore, Judith Kerr, Adrienne R. Thompson, EOP Thompson
The female sex hormone, oestrogen, plays a central role in breast cell proliferation in both the normal and malignant state. It controls transcription from several genes, including that for the progesterone receptor, and in endometrial tissue, via this receptor, it controls the gene for the enzyme oestrogen sulfotransferase. This enzyme may control the level of the oestrogen receptor by su...... hiện toàn bộ
The Evolutionary Significance of Sugar Accumulation in SaccharumCSIRO Publishing - Tập 16 Số 4 - Trang 737 - 1963
T. A. Bull, KT Glasziou
Sugar levels in the various species of the Saccharum complex suggest an evolutionary increase in sugar content. Under suitable ecological conditions, survival through sucker growth may be dependent on rapid mobilization of stored carbohydrate. Selection pressure for sucrose storage would then oocur if sucrose was more readily remobilized than other storage carbohydrates. It is suggested th...... hiện toàn bộ
Activities and Partial Purification of Extracellular Proteases of Bacteroides nodosus from Virulent and Benign FootrotCSIRO Publishing - Tập 35 Số 5 - Trang 481 - 1982
Kortt Aa, IJ O'Donnell, Stewart Dj, BL Clark
In an attempt to differentiate virulent and benign strains of B. nodosus, the extracellular proteolytic activity of these cultures was assayed with elastin, casein and hide powder azure, and the stability to heating at 55�C was determined. Broth cultures of both strains hydrolysed 125I-labelled elastin, indicating that this activity is not a unique marker of virulence. When cultures were g...... hiện toàn bộ
Isozyme Studies on the Origin and Evolution of Puccinia Graminis F. SP. Tritici in AustraliaCSIRO Publishing - Tập 35 Số 2 - Trang 231 - 1982
J. J. Burdon, David Marshall, N. H. Luig, DJS Gow
Isozyme phenotypes for eight enzyme systems were used to assess the origins and evolution of P. graminis f. sp. tritici (the wheat stem rust pathogen) in Australia. The results obtained by this approach agreed with pathways postulated on the basis of virulence studies, confirming the suggestion that most of the major changes in the wheat stem rust pathogen flora of Australia have resulted ...... hiện toàn bộ
Isolation of Choriomammotropin from the Ovine PlacentomeCSIRO Publishing - Tập 37 Số 2 - Trang 63 - 1984
CM Leach Harper, Valerie L. Ford, GD Thorburn
Placentomes, taken from ewes at 101-141 days gestation, were homogenized and subjected to differential and density gradient centrifugation. In the presence or absence of protease inhibitors, choriomammotropin (ovine chorionic somatomammotropin, oCS) was detected by radioimmunoassay, and banded at two positions in 30-60% w/v sucrose gradients. The first band (soluble form) eluted in the sam...... hiện toàn bộ
Testicular and Epididymal Sperm Numbers and Related Parameters in the Developing Awassi RamCSIRO Publishing - Tập 31 Số 3 - Trang 257 - 1978
M. S. S. Abdou, TM Hassun, S. El‐Sawaf
Testicular parameters, parenchymal spermatid concentration, and epididymal sperm reserves were measured in tracts obtained from 16 Awassi rams classified into three age groups (1, 1�5 and 2�5 years old). Between 1 and 2�5 years of age the paired testis weight increased from 164�9 to 315�2 g, the testicular spermatid number (x 109 ) increased from 15�9 to 55�8, and the total epididymal sper...... hiện toàn bộ
A Dpnh-Specific Nitrate Reductase From Germinating WheatCSIRO Publishing - Tập 12 Số 2 - Trang 181 - 1959
Donald Spencer
The isolation and purification of a nitrate reductase from the embryos of germinating wheat is described. This is a soluble enzyme, which is coupled specifically to reduced diphosphopyridine nucleotide (DPNH). Addition of flavin adenine dinucleotide to the purified enzyme results in a three-fold increase in activity. Flavin mononucleotide is without effect. Potassium cyanide and sodium az...... hiện toàn bộ
