Towards a historical ecology of intertidal foraging in the Mafia Archipelago: archaeomalacology and implications for marine resource management

, 2019
Understanding the timing and nature of human influence on coastal and island ecosystems is becoming a central concern in archaeological research, particularly when investigated within a historical ecology framework.

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 ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Predicting taxonomic and functional structure of microbial communities in acid mine drainage. [PDF]

, 2016
Predicting the dynamics of community composition and functional attributes responding to environmental changes is an essential goal in community ecology but remains a major challenge, particularly in microbial ecology.

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.

Contrasting patterns of long-term zoobenthic diversity dynamics in response to sedimentary phosphorus input in eutrophic and mesotrophic lakes

Ecological Indicators
The response of ecosystem structures and functions to eutrophication has been investigated worldwide. Yet, present knowledge on the effects of nutrient inputs on biotic diversity is unsystematic and mainly based on taxonomic composition.

Low functional β-diversity despite high taxonomic β-diversity among tropical estuarine fish communities.

PLoS ONE, 2012
The concept of β-diversity, defined as dissimilarity among communities, has been widely used to investigate biodiversity patterns and community assembly rules. However, in ecosystems with high taxonomic β-diversity, due to marked environmental gradients,

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.

Investigating the effect of forestry on leaf-litter arthropods (Algonquin Park, Ontario, Canada).

PLoS ONE, 2017
Arthropods are the most diverse taxonomic group of terrestrial eukaryotes and are sensitive to physical alterations in their environment such as those caused by forestry.

The central role of soil in shaping terrestrial ferns’ assemblage composition, but not taxonomic diversity, in subtropical Atlantic forests [PDF]

Acta Botânica Brasílica
Understanding the uneven fern distribution is crucial for predicting future changes in their diversity and composition. Here, we explore major subtropical Atlantic Forest' physiognomies, addressing the following questions: 1) Is the current ...
