“…The testes were stained using lacto-acetic orcein following De Vaio et al (1985) and impregnated with silver nitrate following Howell and Black (1980), with modifications. After the usual preparation of the slides, the procedure for the Feulgen reaction was followed according to Mello and Vidal (1980), with modifications, for both species.…”

Spermatogenesis of Zaprionus indianus and Zaprionus sepsoides (Diptera, Drosophilidae): cytochemical, structural and ultrastructural characterization

et al. 2013

Zaprionus indianus is a drosophilid native to the Afrotropical region that has colonized South America and exhibits a wide geographical distribution. In contrast, Z. sepsoides is restricted to certain African regions. The two species differ in the size of their testes, which are larger in Z. indianus than in Z. sepsoides. To better understand the biology and the degree of differentiation of these species, the current study evaluated spermatogenesis in males of different ages by conventional staining techniques and ultrastructural analysis. Spermatogenesis and the ultrastructure of spermatozoa were similar in the two species, and the diploid number was confirmed to be 2n = 12. A greater number of spermatozoa were observed in young Z. indianus (1–3 days old) compared to Z. sepsoides males, which showed a higher frequency of cells at the early stages of spermatogenesis. The head of the sperm was strongly marked by silver staining, lacto-acetic orcein and the Feulgen reaction; the P.A.S. reaction revealed glycogen granules in the testes of both species. Both species presented similar arrangement of microtubules (9+9+2), two mitochondrial derivatives of different size and 64 spermatozoa per bundle. Such similarity within the genus Zaprionus with other species of Drosophila, indicates that these structures are conserved in the family Drosophilidae. The differences observed the number and frequency of sperm cells in the early stages of spermatogenesis, between the young males of Z. indianus and Z. sepsoides, are features that may interfere with reproductive success and be related to the invasive potential of Z. indianus.

“…subsequently, the fragments were submitted to dehydration in a graded series of alcohol for infiltration and embedding in paraffin, or in historesin for thinner microtome sections. Histological sections measuring 5 µm were submitted to staining with Gomori's trichrome (adapted from tolosa et al, 2003) and the periodic acid-schiff (Pas) reaction method (adapted from Junqueira and Junqueira, 1983) for the identification of glycoproteins, or with Ponceau xylidine (adapted from Mello and vidal, 1980) and bromophenol blue (adapted from Pearse, 1960) for total protein. Macroscopic and microscopic aspects of the gonads, including the frequency of germ cells per microscope field and their organisation in the stroma, were used to determine the development stage of the ovary.…”

suMMary: the present study describes the morphology of the female reproductive system and the development of the germ cells of the crab Goniopsis cruentata. specimens were collected monthly from the mangrove of the Ceará river (brazil) for study of the reproductive system. the ovarian lobes unite near the middle of the cephalothorax and extend to the third abdominal segment. the ovaries connect to spermathecae draining into a short oviduct. Microscopically, four types of germ cells were identified. Four stages of ovary development were defined based on macroscopic and microscopic features. the association of ovary development stages with biometric measures shows that ovaries of females with triangular abdomens and a carapace width (CW) of 21.0-29.3 mm were in the previtellogenic stage, while those of females with rounded abdomens and a CW of 26.4-46.1 mm varied with regard to maturity, the majority being late-stage vitellogenic or mature. the organisation of the female reproductive system of G. cruentata is similar to that of most other brachyurans, except for the extension of the ovaries to the abdomen.Keywords: reproduction, brachyura, oogenesis, mangrove.resuMen: Morfología del sistema reproductivo de las hembras del cangrejo rojo de mangle (Goniopsis cruentata Latreille, 1803). -el presente estudio describe la morfología del sistema reproductivo femenino y el desarrollo de las células germinativas del cangrejo Goniopsis cruentata. Los ejemplares estudiados fueron recolectados mensualmente en un manglar del río Ceará (brasil). en plena madurez, los lóbulos del ovario se unen cerca del centro del cefalotórax y se extienden hasta el tercer segmento abdominal. Los ovarios se conectan a la espermateca a través de un pequeño oviducto. Microscópicamente, cuatro tipos de células germinativas fueron identificadas. Cuatro estadios de desarrollo ovárico fueron definidos en base a características macroscópicas y microscópicas. La asociación del desarrollo de los estadios de desarrollo ovárico con medidas biométricas muestra que los ovarios de las hembras con abdómenes de forma triangular y talla comprendida entre 21-29.3 mm de anchura de cefalotórax se encuentran en el estadio pre-vitelogénico, mientras que los ovarios de hembras con abdómenes redondeados y tallas comprendidas entre 26.4-46.1 mm varían en relación a su grado de desarrollo, la mayoría perteneciendo al estadio vitelogénico tardío o maduro. La organización del sistema reproductivo femenino de G. cruentata es similar al de la mayoría de otros cangrejos braquiuros, excepto por la extensión de los ovarios al abdomen.

“…Jefkins (1987) describes it as "a statement made to the media by an authorized person who does not wish to be named," and who may be, for example, a politician who is willing to speak as long as the data is published without attribution.

-The social nature of journalism forces this activity to take place only in the face of alterity and from it. To narrate the facts, the journalist resorts to the Other -as a source of information -and the product of this work is destined to another Other, the audience. Information publicity and privacy regimes are related to alterity in journalism. Privacy is an individual right that can constrain a collective right, for example. To deepen the debate, this article identifies how privacy presents itself in the academic bibliography and ten area dictionaries over five decades. The results point to rarity, outdatedness and insufficiency in the treatment of the subject in journalism. Keywords: Privacy. Journalism. Dictionaries. Professional Jargon. Journalistic Lexicon.
