Alterations in Lipid Levels of Mitochondrial Membranes Induced by Amyloid‐β: A Protective Role of Melatonin

International Journal of Alzheimer’s Disease, Volume 2012, Issue 1, 2012., 2012
Alzheimer pathogenesis involves mitochondrial dysfunction, which is closely related to amyloid‐β (Aβ) generation, abnormal tau phosphorylation, oxidative stress, and apoptosis. Alterations in membranal components, including cholesterol and fatty acids, their characteristics, disposition, and distribution along the membranes, have been studied as ...

Mechanisms for the Spin‐State Switching of Strapped Ni‐Porphyrin Complexes Deposited on Metal Surfaces: Insights from Quantum Chemical Calculations

Small, Volume 21, Issue 2, January 15, 2025.
State‐of‐the‐art quantum chemistry methods are used to characterize the spin switching of strapped Ni porphyrin molecules deposited on Ag(111) surface. The LS and HS states are related by a vertical shift of the pyridine ligand, that modifies the Ni coordination number and promotes the spin transition. The voltage‐dependent spin switching is related to

Land Use Change Consistently Reduces α‐ But Not β‐ and γ‐Diversity of Bees

Global Change Biology, Volume 31, Issue 1, January 2025.
We analyzed a global dataset of 3117 bee assemblages across 157 studies to assess how bee diversity varies among natural, agricultural, and urban habitats. We measured diversity using both the number of bee taxa (taxonomic diversity) and their evolutionary relationships (phylogenetic diversity).

Fruit production in coffee (Coffea arabica L.) crops is enhanced by the behaviour of wild bees (Hymenoptera: Apidae)

Austral Entomology, Volume 63, Issue 1, Page 82-94, February 2024.
Abstract Changes in floral visitors' diversity and community composition have been reported to affect coffee production, which optimal growing conditions are cool to warm tropical climates found in the coffee belt. However, few studies have focused on understanding how insects' foraging behaviour (e.g., contact with floral reproductive organs) relates ...
