Alumínio estimula o crescimento radicular de erva-mate?

Pesquisa Florestal Brasileira, 2017
A toxicidade por Al em plantas se dá de várias maneiras, sendo a inibição do crescimento radicular uma das primeiras a se expressar, embora não seja prontamente perceptível em razão do hábito de crescimento das raízes. O objetivo desse trabalho foi avaliar a tolerância da erva-mate ao Al por meio do crescimento de raízes de mudas submetidas a doses ...

Methane Transport Pathways and Oxidation in a Minnesota Bog

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Despite the widely recognized importance of wetland CH4 emissions as a climate change feedback, simultaneous measurements of CH4 transport pathways and oxidation in a wetland are rare. Thus, these critical components of many CH4 models are poorly parameterized because of the lack of appropriate data.

Insomnia and sleepiness during pregnancy: Associations with gestational diabetes mellitus

Acta Obstetricia et Gynecologica Scandinavica, Volume 104, Issue 9, Page 1742-1758, September 2025.
Insomnia increases and sleep quality worsens during pregnancy, but mostly independent of GDM diagnoses. Our study shows that sleepiness is more common in women with GDM in early and mid‐pregnancy, especially in women needing pharmacotherapy for GDM. It seems that sleep development is more important than sleep at individual time‐points.

Perceived eggshell luminance does not predict rejection of experimental egg models in eastern bluebirds

Journal of Avian Biology, Volume 2025, Issue 4, July 2025.
Obligate avian brood parasites lay their eggs in other bird species' nests, leaving these hosts to rear the parasitic young. To eliminate or reduce the costs of parasitism, many hosts have evolved the ability to recognize and reject parasitic eggs, and most use eggshell color for recognition; however, color discrimination should be more challenging in ...

New Insights on the Crustal Deformation in the Eastern Betics From Densified GNSS Data

Tectonics, Volume 44, Issue 2, February 2025.
Abstract The Eastern Betic cordillera, southeastern Spain, is characterized by slow tectonic deformation rates and moderate seismicity. Great uncertainties persist regarding the precise kinematics of the main fault system within the region, the Eastern Betic Shear Zone (EBSZ). We present a new GNSS (Global Navigation Satellite System) velocity field in

Gestational Duration and Postnatal Age‐Related Changes in Aperiodic and Periodic Parameters in Neonatal and Toddler Electroencephalogram (EEG)

Human Brain Mapping, Volume 46, Issue 1, January 2025.
This study explores the association between gestational duration and brain electrophysiological activity, using EEG data from neonates and toddlers. Our results indicate that longer gestation correlates with a steeper EEG power spectrum in both neonates and toddlers, suggesting that gestational duration may have significant and relatively long‐lasting ...

Symmetrical 2,7‐disubstituted 9H‐fluoren‐9‐one as a novel and promising scaffold for selective targeting of SIRT2

Archiv der Pharmazie, Volume 357, Issue 12, December 2024.
Lead optimization was conducted and a new scaffold of SIRT2‐selective inhibitors was discovered. The top compound SG3 selectively inhibited SIRT2 with an IC50 value of 1.95 μ M and reduced the MCF‐7 cell viability, accompanied by hyperacetylation of α‐tubulin. In silico studies verified the binding ability of SG3 to SIRT2.
