Nut density and removal in Syagrus loefgrenii Glassman (Arecaceae) in the Brazilian Cerrado

Brazilian Journal of Biology
In this study, I tested the effect of Syagrus loefgrenii nut number on the removal intensity by rodents across seasons. Also, I assessed both S. loefgrenii fruit production, and dispersion pattern to analyze the relationship between these parameters and ...

Biological Plausibility of the Pace of Creation Written in the Genesis [PDF]

, 2012
The purpose of this paper is to discuss the biological plausibility of the pace of creation written in the genesis. A fascinating hypothesis is made on the central role of serotonin as a guide, as the director of the phenomena that ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

A potential ant-hemiptera-plant mutualism on Lorostemon coelhoi (Clusiaceae) in the Brazilian Amazon [PDF]

Acta Amazonica
Interactions among organisms are important in ecosystem functioning and relevant for the management and conservation of species. Here we report the first record of a potential ant-hemiptera-plant mutualism on Lorostemon coelhoi (Clusiaceae) in Manaus ...

Dying to Eat: Terror Management and Attitudes Toward Eating Plants [PDF]

, 2018
Terror management theory posits that the drive for self-preservation and the knowledge of our inevitable death create anxiety in people, which they manage in a variety of ways, including favoring those who are like them and distancing themselves from ...

T-loop phosphorylation of Arabidopsis CDKA;1 is required for its function and can be partially substituted by an aspartate residue [PDF]

, 2007
As in other eukaryotes, progression through the cell cycle in plants is governed by cyclin-dependent kinases. Phosphorylation of a canonical Thr residue in the T-loop of the kinases is required for high enzyme activity in animals and yeast.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Possible origins of macroscopic left-right asymmetry in organisms

, 2012
I consider the microscopic mechanisms by which a particular left-right (L/R) asymmetry is generated at the organism level from the microscopic handedness of cytoskeletal molecules.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
