The release of prolactin in response to a standard dose of thyrotrophin releasing hormone for amenorrhoeic subjects with normal basal levels of prolactin was within the normal range. However, patients with hyperprolactinaemic amenorrhoea and no evidence of pituitary tumour were found to have a blunted response.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract A model is proposed to predict the ability of a filler to reinforce a polymer. The model combines the effects of filler particle size, filler surface chemistry and filler volume fraction into one parameter called the bond energy density. Bond energy density is defined as the total interfacial bond energy per unit volume of a polymer composite. Bond energy density is determined by Fowkes's equation. The critical bond energy density, which is equivalent to the bond energy density of the composite when its tensile strength equals that of its matrix, determines whether a filler will reinforce or weaken a polymer. To get a filler reinforcing effect, the bond energy density of the composite must be greater than its critical bond energy density.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1573-7276Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract PNKT-4B is an aneuploid cell line derived from a herpesvirus-induced renal adenocarcinoma of Rana pipiens that displays restricted invasion at 21°C or cooler and invasion at 23°C through 28°C. Metaphase chromosomes obtained from subcultures (passages 297; 345–347) grown at 18°C or 28°C were Giemsa stained or N-banded with acidic silver nitrate. Cells grown at 18°C displayed a modal chromosome number of 41, while 28°C cultures displayed a modal number of 40. The distribution of the chromosomes suggests that the two temperatures may be allowing growth of different subclonal populations. N-banding of chromosomes at both temperatures revealed an increase of active nucleolar organizer regions (NORs) over normal frog tissues, 2/2N. Analysis of 200 N-banded spreads from cells grown at each temperature revealed modal numbers of 9 NORs/cell and modal numbers of 6 NOR-containing chromosomes/cell. Nine specific NOR-containing chromosomes were identified and scored. Similar distributions were observed at 18°C and 28°C. The data imply that the modal number of PNKT-4B has shifted since it was first described, 39, and differs at invasion-permissive and — restrictive temperatures. Increased numbers of active NORs and alterations of NOR-containing chromosomes imply an amplification of rDNA over the amount in normal frog.Type of Medium: Electronic ResourceURL: -

Published 1989Staff ViewISSN: 1572-9931Source: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Abstract X-chromosome inactivation was investigated in human chorionic villi in the first trimester of pregnancy and cultured cells established from them. Expression of glucose-6-phosphate dehydrogenase (G6PD) was evaluated in these extraembryonic cells from four females heterozygous for the electrophoretic variants (AB) of G6PD. In each case the uncultured villi as well as derived cultured cells expressed the AB phenotype for G6PD with about equal intensity for the A and B bands. Single-cell-derived clones established from two of the four cases expressed either G6PD A or B. One clone expressing G6PD B was fused with mouse cells, and a hybrid clone retaining the inactive human X chromosome was isolated; there was no evidence of human G6PD expression in this clone retaining an inactive human X. DNA methylation in the first intron of the human gene for hypoxanthine phosphoribosyltransferase (HPRT) was evaluated in the four pairs of cultured villi and fetal cells. No differences were detected between the cultured villi and fetal cells as they all showed bands characteristic of an inactive X from somatic cells. These results show that there is no preferential inactivation of an X in the majority of cells that constitute human tertiary chorionic villi or in cultured cells derived from them. Long-term cultures established from chorionic villi appear to be no different from somatic cells with respect to X-chromosome inactivation.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5117Keywords: Mysidacea ; aquatic toxicology ; toxicology ; Mysidopsis bahia ; silver ; endosulfan ; growth ; reproductionSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The chronic toxicity of silver and endosulfan to the opossum shrimpMysidopsis bahia was determined using continuous-flow bioassays. The 28-day bioassays measured survival, fecundity, and growth (length and weight measurements). Maximum acceptable toxicant concentrations (MATC) were estimated from measured toxicant concentrations. MATC values were similar using either brood size or growth as a criterion for sublethal effects. As an alternative to the determination of fecundity impairment, measurement of growth reduction in response to exposure to toxicants may provide a useful tool in the assessment of chronic toxicity inMysidopsis life-cycle bioassays.Type of Medium: Electronic ResourceURL:
