    • Effect of progesterone and first evidence about allopregnanolone action on the progression of epithelial human ovarian cancer cell lines 

      Pelegrina, Laura Tatiana; Sanhuesa, María de los Ángeles; Cáceres, Antonella Rosario Ramona; Cuello Carrión, Dario; Rodríguez, Cristina Elisa; Laconi, Myriam Raquel (Comité editorial Journal of Steroid Biochemistry and Molecular Biology, 2020-02)
      Ovarian carcinoma is one of the most common cause of death by gynecologic cancer. Several epidemiological and in vitro studies have shown controversial data about progesterone effects in ovarian cancer. Progesterone can be converted in its active metabolite, allopregnanolone, its effects in ovarian cancer are still unknown. Previously, we demonstrated that allopregnanolone modifies ovarian morphophysiology, being able to alter critical process of tumor development such as proliferation, apoptosis and angiogenesis. Taking into account these antecedents, we investigated the effect of progesterone ...

    • Effect of the length of the suckling period and dietary energy intake in lactation on the duration of postpartum anestrus in Creole goats. 

      Paez Lama, Sebastián Antonio; Grilli, Diego; Egea, Vanina; Fucili, Mercedes; Allegretti, Liliana; Guevara, Juan Carlos; Jahn, Graciela Alma (Comité editorial Small Ruminant Research, 2016-04-16)
      The objective of this study was to determine the effect of the length of the suckling period and the dietary energy level on the duration of postpartum anestrus in Creole goats. Twenty-eight multiparous pregnant goats (bodyweight BW 39.9 ± 6.4 kg; mean ± SEM) each bearing a single fetus were used in a 2 suckling period (30 vs. 60 d) × 2 levels of energy intake (low (L) vs. high (H)) factorial design. Kids were separated from their dams 3 d after birth and then suckled twice per day until weaned at 30 or 60 d postpartum. Dams weaned at 30 d postpartum were hand milked for the next 30 d. Goats ...

    • Emerging insights into hypothalamic-pituitary- gonadal axis regulation and interaction with stress signalling. 

      Acevedo-Rodríguez, Alexandra; Kauffman, Alexander; Cherrington, Brian; Borges, Cibele; Roepke, Troy; Laconi, Myriam (Comité editorial Journal of Neuroendocrinology, 2018-10-30)
      Reproduction and fertility are regulated via hormones of the hypothalamic-pituitary-gonadal (HPG) axis. Control of this reproductive axis occurs at all levels, including the brain and pituitary, and allows for the promotion or inhibition of gonadal sex steroid secretion and function. In addition to guiding proper gonadal development and function, gonadal sex steroids also act in negative-and positive-feedback loops to regulate reproductive circuitry in the brain, including kisspeptin neurones, thereby modulating overall HPG axis status. Additional regulation is also provided by sex steroids made ...

    • Epidemiological link between canine monocytic ehrlichiosis caused by Ehrlichia canis and the presence of Rhipicephalus sanguineus sensu stricto in Argentina 

      Sebastian, Patrick; Mera y Sierra, Roberto; Neira, Gisela; Hadid, Jaled; Flores, Fernando; Nava, Santiago (Parasitology Research Editorial, 2021-01-08)
      In this work, we analyze data that support an epidemiological link between cases of canine monocytic ehrlichiosis (CME) by Ehrlichia canis and the presence of Rhipicephalus sanguineus sensu stricto as vector in an endemic area for this tick in Argentina. In a blood sample of a 1-year-old toy poodle with CME compatible clinical signs, which showed CME typical morulae in monocytes in Giemsa-stained blood smear, DNA of E. canis was detected by PCR. Further, DNA of E. canis was also detected in a female of R. sanguineus s.s. collected on the infected dog. Rhipicephalus sanguineus s.s. is the only ...

    • Erythrocyte micronucleus cytome assay of 17 wild bird species from the central Monte desert, Argentina. 

      Quero, Arnoldo Ängel Martín; Ferré, Daniela Marisol; Zarco, Agustín; Cuervo, Pablo Fernando; Gorla, Nora Bibiana María (Editorial Environmental Science and Pollution Research, 2016-09-29)
      Birds have the potential to be considered valuable bioindicators of the quality of ecosystems and the environmental impact of pollutants. The aims of this study were to determine the micronuclei frequency and other nuclear abnormalities in erythrocytes by analyzing a wild bird community from central Monte desert (Argentina) and to clarify if there were any differences among certain species. Frequencies of nuclear abnormalities were determined in 73 wild birds belonging to 17 species and two orders (Passeriformes and Columbiformes). A high proportion of individuals, 90.4 and 80.9 %, had erythrocytes ...

    • Evaluation of the genotoxic potential of cypermethrin, chlorpyrifos and their subsequent mixture, on cultured bovine lymphocytes 

      Ferré, Daniela Marisol; Ludueña, Héctor Ricardo; Romano, Raquel; Gorla, Nora Bibiana María (Comité editorial Chemosphere Journal, 2019-11-09)
      Cypermethrin (CYP) and chlorpyrifos (CPF) are insecticides/parasiticides used in the production of fruits, vegetables and beef cattle. These substances or their metabolites are frequently reported as residues in food, whose consumption in a diet implies a genotoxic risk. The potential for chronic toxicity of CYP and CPF is unclear, and only a few genotoxicological evaluations based on their mixture have been performed. The aim of this study was to evaluate the genotoxic potential of CYP, CPF and CYP þ CPF in five concentrations, from 5.9 to 175 mg/mL, on bovine lymphocytes. By means of the ...

    • In vivo assessment of closantel ovicidal activity in Fasciola hepatica eggs. 

      Solana, María Victoria; Mera y Sierra, Roberto; Scarcella, Silvana; Neira, Gisela; Solana, Hugo Daniel (Editorial Experimental Parasitology, 2016)
      Anthelmintic resistance in livestock parasites is currently a worldwide problem. Fasciola hepatica is a cosmopolitan parasite which causes considerable loss in sheep and cattle production systems all over the world. Chemotherapy is currently the main tool available for its control. The intensive use of triclabendazole, the drug of choice for more than 20 years, has resulted in the development of resistant strains. The therapeutic options are adulticides such as closantel (salicylanilide anthelmintic that binds extensively to plasma albumin) to treat chronic fascioliasis in sheep, and cattle. In ...
