Dasatinib and quercetin prevent alveolar bone loss in aged mice

Journal of Periodontology, EarlyView.
Abstract Background Recent findings have associated alveolar bone loss (ABL) with the presence of senescent cells. Aging and the accumulation of senescent cells are associated with a pro‐inflammatory environment which may exacerbate tissue damage.

Fish Migration Through Ship Locks at the Danube River, Austria

River Research and Applications, EarlyView.
ABSTRACT Longitudinal connectivity in the Austrian section of the Danube has improved over the last three decades thanks to the progressive installation of fish passage facilities at hydropower plants. However, navigation locks which are present at all barrages remain poorly quantified with respect to their role in fish migration.

Decreased nitric oxide levels in the hippocampus may play a role in learning and memory deficits in ovariectomized rats treated by a high dose of estradiol

Arquivos de Neuro-Psiquiatria, 2012
The effects of a high estradiol dose on memory and on nitric oxide metabolites in hippocampal tissues were investigated. Sham-Est and OVX-Est Groups were treated with 4 mg/kg of estradiol valerate for 12 weeks.

After All, Size Does Matter: Size and Trachemys Scripta Reproduction Traits at the Western Limit of Its European Distribution

Integrative Zoology, EarlyView.
‐ Female T. scripta exhibit a clear size‐dependent reproductive investment, where larger plastron length is positively associated with all key reproductive traits. ‐ Female T. scripta reach sexual maturity at a plastron length of approximately 15–18 cm. ABSTRACT In invasive species, reproductive success may determine invasion outcomes and influence the

Avaliação radiográfica e histomorfométrica da mandíbula de ratas medicadas com corticóide e bifosfonato

Revista da Faculdade de Odontologia de Porto Alegre, 2009
Glicocorticóides e bifosfonatos são medicamentos que interferem na estrutura óssea. Para avaliar se estas mudanças se manifestam radiográfica e histologicamente na mandíbula, foram utilizadas 36 ratas Wistar, divididas em três grupos de 12 animais.
