Nutritional deficiency and placenta calcification underlie constitutive, selective embryo loss in pregnant South American plains vizcacha, Lagostomus maximus (Rodentia, Caviomorpha)
(Elsevier, 2020-10)
Plains vizcacha females are able to ovulate up to 800 oocytes per estrus cycle. However, just 10–12 embryos are implanted and only two of them, those located nearest the cervix, are gestated to term. Between 26 and 70 days ...
Osteopathology and selenium deficiency co-occurring in a population of endangered Patagonian huemul (Hippocamelus bisulcus) Veterinary Research
(BioMed Central, 2015-08)
Background: About 1,000 endangered Patagonian huemul deer (Hippocamelus bisulcus) remain in Chile and 350-500 in Argentina. Most groups (>100) are not recovering, and prevalence of osteopathology in Argentina was at least ...
Nutritional marginal zinc deficiency disrupts placental 11β-hydroxysteroid dehydrogenase type 2 modulation
(Royal Society of Chemistry, 2016-01)
This paper investigated if marginal zinc nutrition during gestation could affect fetal exposure to glucocorticoids as a consequence of a deregulation of placental 11βHSD2 expression. Placenta 11β-hydroxysteroid dehydrogenase ...
Effects of Nutritional Deficiency of Boron on the Bones of the Appendicular Skeleton of Mice
(Humana Press, 2018-09-04)
Scientific evidence has shown the nutritional importance of boron (B) in the remodeling and repair of cancellous bone tissue. However, the effects of the nutritional deficiency of B on the cortical bone tissue of the ...
Nitric oxide and plant mineral nutrition: current knowledge
(Oxford University Press, 2019-03)
Plants under conditions of essential mineral deficiency trigger signaling mechanisms that involve common components. Among these components, nitric oxide (NO) has been identified as a key participant in responses to changes ...
Contribution of Gluconacetobacter diazotrophicus to phosphorus nutrition in strawberry plants
(Springer, 2017-10)
Background and Aims: Gluconacetobacter diazotrophicus (family Acetobacteraceae), is a N2-fixing bacterium with capability of mineral solubilization through organic acid production. The aim of this work was to evaluate its ...
Effects of maternal vitamin B12 deficiency from end of gestation to weaning on the growth and haematological and immunological parameters in mouse dams and offspring
(Taylor & Francis, 2008-03-04)
Vitamin B12-deficiency may induce specific symptoms as neurological alterations and unspecific symptoms such as anaemia and growth retardation. In this study, maternal vitamin B12 deficiency from end of gestation to weaning ...
Antibiotic resistance in Zn(II)-deficient environments: Metallo-β-lactamase activation in the periplasm
(Future Medicine, 2013-08)
Zn(II) is an essential metal ion in living organisms, playing a wide variety of roles as a structural, regulatory or catalytic cofactor in proteins, that is able to interact with approximately 10% of the entire proteome ...
Alterations of the extracellular matrix of lung during zinc deficiency
(Cambridge University Press, 2012-07)
Suboptimal intake of Zn is one of the most common nutritional problems worldwide. Previously, we have shown that Zn deficiency (ZD) produces oxidative and nitrosative stress in the lung of rats. We analyse the effect of ...
