Caracterización histológica e histoquímica de branquia, hígado y riñón de perca criolla ( Percichthys trucha, Valenciennes, 1833 ) para su uso en biomonitoreo ambiental
(Comité editorial Acta microscópica, 2017-12)El objetivo de esta investigación fue realizar la descripción histológica de los principales órganos blanco de contaminantes ambientales en Percichthys trucha, pez nativo y ampliamente distribuido en ríos y lagos del sur de Argentina. Se capturaron sesenta especímenes adultos sanos de tamaño y peso similar, en Embalse El Nihuil, Mendoza, Argentina. Se describieron macroscópicamente las branquias, el hígado y el riñón y se fijaron en formalina neutra bufferada al 10% para su inclusión y tinción con hematoxilina eosina, ácido peryódico de Schiff (PAS), tricrómico de Masson y azul de Alcian.

Diet mixing and condensed tannins help explain foraging preferences by Creole goats facing the physical and chemical diversity of native woody plants in the central Monte desert (Argentina).
(Comité editorial Animal Feed Science and Technology, 2016-02-26)The aim of this study was to understand the benefit of diet mixing for Creole goats grazingnative forage species in the central Monte desert of Argentina and the drivers of preferencein the mixed diet. To achieve this goal, cafeteria-style experiments were conducted withthirty female Creole goats (2 years old; 44 ± 1.4 kg) and forage species that are typicallyingested by goats in this region: Two tanniniferous (Tricomaria usillo, Mimosa ephedroides)and three non-tanniniferous shrubs (Prosopis flexuosa, Capparis atamisquea, Atriplex lampa).In Experiment 1, goats were assigned to three groups (n ... -

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