35. Structure of spermatodesms of Orthoptera Tettigonioidea

Author

Viscuso, R., Narcisi, L., Sottile, L., and Barone, N.

Abstract

Examination of spermatodesms collected from the male and female genital tracts of numerous Orthoptera Tettigonioidea revealed an overall morphological and ultrastructural organization that is generally similar in individuals of the same sex but considerably different between males and females of even the same species. In the male genital tracts each spermatodesm is composed of a limited number of spermatozoa whose nuclei and acrosomes are covered by a mucous cap. The spermatozoa inside each bundle are mainly arranged in parallel rows and are always distinctly separate. The number of spermatozoa per spermatodesm may vary within the same individual although it does not seem to exceed a maximum value that we could only determine exactly in Tettigoniidae species. The most characteristic feature of spermatozoa of all the species examined is a conspicuous elongation of the plasma membrane in the acrosomal region that is not present in the female genital tracts. In addition, spermatodesms from females are composed of highly numerous tightly packed spermatozoa that are linked together via the acrosomal region. This characteristic of spermatodesms, never previously reported in other insect species, would involve their reorganization during transfer from the male to the female genital tracts and would seem to take place in the spermatophore. The probable role of spermatodesms in the reproductive physiology of Tettigonioidea might be related to the degree of maturity of the sex cells transferred to the female; the reorganization of the spermatozoa out of the male genital tracts seems to support this hypothesis.

42. Structure of male accessory glands of Bolivarius siculus (fischer) (Orthoptera, Tettigoniidae) and protein analysis of their secretions.

Abstract

In Tettigoniidae (Orthoptera), male reproductive accessory glands are involved in the construction of a two-part spermatophore; one part, the spermatophylax, is devoid of sperm and considered a nuptial gift. The morphology, ultrastructure, and secretion protein content of the male reproductive accessory glands from Bolivarius siculus were investigated. Two main groups of gland tubules open into the ejaculatory duct: the "first-order" glands, a number of large anterior tubules, and the "second-order" glands, smaller and more numerous tubules positioned posteriorly. Along with a further subdivision of the gland tubules, we here describe for the first time an additional gland group, the intermediate tubules, which open between first and second-order glands. The mesoderm-derived epithelium of all glands is a single layer of microvillated cells, which can be either flattened or cylindric in the proximal or distal region of the same gland. Epithelial cells, very rich in RER and Golgi systems, produce secretions of both electron-dense granules and globules or electron-transparent material, discharged into the gland lumen by apocrine or merocrine mechanisms, respectively. With one exception, a unique electrophoresis protein profile was displayed by each of the gland types, paralleling their unique morphologies. To assess the contribution of different types of accessory glands to the construction of the spermatophore, the protein patterns of the gland secretions were compared with those of the extracts from the two parts of the spermatophore. All samples showed bands distributed in a wide range of molecular weight, including proteins of very low molecular mass. However, one major high molecular weight protein band (>180 kDa) is seen exclusively in extracts from the first-order glands, and corresponds to an important protein component of the spermatophylax., ((c) 2009 Wiley-Liss, Inc.)

43. Mode of transfer of spermatozoa in Orthoptera Tettigoniidae.

Abstract

A morphological and ultrastructural study was carried out on the spermatophore and spermatodoses of some species of Orthoptera Tettigoniidae. From the results concerning the spermatophore it emerged that this structure has a morphological and ultrastructural organization represented by a dilated ampulla and a peduncle or neck. From the examination of freshly deposited spermatophores and those at various time intervals thereafter, it was seen that these structures other than allowing gamete transfer, represent the site where spermatodesms, organized in the male genital tracts, undergo reorganization to acquire their definitive morphological and structural characteristics as found in the female genital tracts. The spermatodoses, in the same way as the spermatophore, represent capsules containing spermatodesms, which are originated in the spermatheca, their specific morphology seems to diversify according to the species considered. As regards their role, it is hypothesized that these structures represent a long-term conservation mechanism for spermatozoa inside the seminal receptacle.

Abstract

Background: The aim of this study was to evaluate whether a family history of hypertension is associated with haemostatic disorders., Methods: In 38 normotensive subjects with a family history of hypertension (relatives) and in 46 sex, age and body mass index matched controls with no family history of hypertension, tissue-type plasminogen activator (t-PA), plasminogen activator-inhibitor (PAI-1), D-dimer (DD) and prothrombin fragment 1+2 (F1+2) were evaluated., Results: The t-PA and PAI-1 observed values were significantly higher than the values detected in the controls., Conclusions: These data seem to suggest a correlation between family history of hypertension and haemostatic disorders.

Abstract

Methods are presented for the preparation of a variety of D-fructose phosphates, 13C-substituted at any single carbon site or at any two symmetrically disposed carbon sites, from either 13C-substituted pyruvate or L-alanine. It is demonstrated that millimole quantities of product can be obtained in good yield following a "one-pot" incubation of 13C-substituted precursors with commercially available enzymes and cofactors of the glycolytic pathway. Since it has previously been shown that a wide variety of aldehydes serve as acceptable substrates for the final rabbit muscle aldolase-catalyzed condensation step, the method can potentially be applied to prepare a wide variety of 13C-substituted sugars and sugar phosphates.

46. Lectin binding to the egg envelopes in Eyprepocnemis plorans (Charp.) (Orthoptera, Acrididae).

Abstract

The distribution of glycoconjugates in the egg envelopes of Eyprepocnemis plorans was investigated using various FITC-conjugated lectins. In the epichorion, the lectins ConA, SBA and WGA each have particular binding patterns, while TPA binding is confined to its deepest regions only. The glycoconjugates of the micropylar wall present different characteristics from those of the surrounding chorion. The vitelline coat shows a marked binding for WGA and TPA only; below the inner micropylar openings, this binding pattern is uniform over the whole extent of the coat and therefore it is not possible to identify specific binding sites for these two lectins. Contrary to what has been observed in some other insect species, the vitelline coat does not seem to be involved in the structural organization of the mycropyles.
