    Notes: Five types of sensilla are situated on the apical area of the labial and maxillary palpi and galea of Cicidela sexguttata. Large, conical, and peg-like sensilla are in rows on the central region of each palpus. These sensilla have a hollow cuticular peg, with an apical pore and multi-innervation. This central region of palpal sensilla is surrounded by campaniform sensilla that are disc-shaped and small conical peg sensilla. A similar type of conical sensillum as the found in the palpal central region is situated around the periphery of the palpal apex and apex of the galea. This conical peg sensillum is located in a shallow depression and is structurally similar to the other peg sensilla, but it has a mechanoreceptor neuron attached to the cuticular base of the sensillum. A long, single, trichoid sensillum is situated in the center of the galea and is hollow, thick-walled, porous, and multi-innervated. The apices of the palpi and galea have a large number of dermal gland openings that actively secrete a substance during the feeding process of the tiger beetle. © 1995 Wiley-Liss, Inc.

    Notes: Comparisons have been made of the weights of the suprarenals of 525 mature female dogs in dioestrus, oestrus, pregnancy and lactation. Tables and graphs show that there was a slight increase in the size of the suprarenals during oestrus. There was hypertrophy of both the cortex and the medulla in the oestrous dogs. Only slight increase was shown in the weights of the glands of pregnant animals when the net body weight was considered and no increase when the total body weight was used in the study. There was no hypertrophy of the glands of lactating animals.There was only a slight variation in the seasonal occurrence of oestrus. From 34 to 37% of the total numbers of mature females examined in the seasons were found to be in oestrus. From 13 to 16% of the total numbers were found to be pregnant.

    Notes: Epithelial ovarian cancer is a heterogenous disease. Epidemiologic studies have identified risk factors for this disease including advanced age, nulliparity, history of infertility, early age at menarche, late age at menopause, and perhaps ovulation induction. Cohort selection that includes women who have potential precursor lesions and alterations of select biomarkers may prove useful in the design of chemoprevention trials of epithelial ovarian cancer. Nuclear morphometry, specific genetic alterations, and markers of proliferation and differentiation may be useful biomarker to monitor the efficacy of specific interventions.

    Notes: Women at risk of uterine cancer include those with one or more of the following characteristics: obesity, nulliparity, late menopause, diabetes mellitus, prolonged unopposed estrogen use, and tamoxifen therapy. Risk is additionally increased by the presence of endometrial hyperplasia. The incorporation of biomarkers into the selection criteria of cohort groups at risk for developing endometrial cancer offers an innovative approach to the clinical design of chemoprevention trials of endometrial adenocarcinoma. Biomarkers that may be useful in cohort selection include nuclear morphometry, specific genetic abnormalities, and markers of proliferation and differentiation.

    Notes: 11β-hydroxysteroid dehydrogenases regulate glucocorticoid concentrations and 17β-hydroxysteroid dehydrogenases regulate estrogen and androgen concentrations in mammals. Phylogenetic analysis of the sequences from two 11β-hydroxysteroid dehydrogenases and four mammalian 17β-hydroxysteroid dehydrogenases indicates unusual evolution in these enzymes. Type 1 11β- and 17β-hydroxysteroid dehydrogenases are on the same branch; Type 2 enzymes cluster on another branch with β-hydroxybutyrate dehydrogenase, 11-cis retinol dehydrogenase and retinol dehydrogenase; Type 3 17β-hydroxysteroid dehydrogenase is on a third branch; while the pig dehydrogenase clusters with a yeast multifunctional enzyme on a fourth branch. Pig 17β-hydroxysteroid dehydrogenase appears to have evolved independently from the other three 17β-hydroxysteroid dehydrogenase dehydrogenases; in which case, the evolution of 17β-hydroxysteroid dehydrogenase activity is an example of functional convergence. The phylogeny also suggests that independent evolution of specificity toward C11 substituents on glucocorticoids and C17 substituents on androgens and estrogens has occurred in Types 1 and 2 11β- and 17β-hydroxysteroid dehydrogenases.

    Notes: A set of yeast strains based on Saccharomyces cerevisiae S288C in which commonly used selectable marker genes are deleted by design based on the yeast genome sequence has been constructed and analysed. These strains minimize or eliminate the homology to the corresponding marker genes in commonly used vectors without significantly affecting adjacent gene expression. Because the homology between commonly used auxotrophic marker gene segments and genomic sequences has been largely or completely abolished, these strains will also reduce plasmid integration events which can interfere with a wide variety of molecular genetic applications. We also report the construction of new members of the pRS400 series of vectors, containing the kanMX, ADE2 and MET15 genes. © 1998 John Wiley & Sons, Ltd.

    Description: Backazimuth estimates derived from surface wave polarization can be used to test association of an observed surface wave with a seismic event. However, commonly used techniques for estimating the backazimuth are subject to a number of errors and are often inaccurate. We evaluate the performance of a new algorithm for determining Rayleigh wave propagation direction from the cross-correlation of the horizontal and Hilbert transformed vertical seismograms. This proves to be more accurate and much less error-prone than current automatic processing procedures, and the cross-correlation value provides a good measure of the reliability of the backazimuth estimate. Consequently, the new algorithm will permit more reliable event association at a lower magnitude threshold.
