Evaluating endophyte‐rich leaves and leaf functional traits for protection of tropical trees against natural enemies

open access: yesFunctional Ecology, Volume 39, Issue 2, Page 371-389, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants use physical barriers and chemical compounds to defend themselves against natural enemies. For instance, tough leaves are considered to be better defended than soft leaves, part of a spectrum of defences defined by functional traits such as leaf chemistry ...

Supplementation of the Probiotic LLH135 Reduces Oxidative Stress in a Model of Hemiparkinsonism

open access: yesBehavioural Neurology, Volume 2025, Issue 1, 2025.
Oxidative stress and neuroinflammation are considered as the two main etiological reasons behind idiopathic Parkinson’s disease (PD). Nevertheless, the actual treatments are focused on improving motor symptoms by restoring dopamine (DA) presence, leaving said causes unattended.

Analysis of the immunomodulatory properties of mycobacterium cell wall fraction on the cytokine production of peripheral blood mononuclear cells of healthy dogs

open access: yesVeterinary Dermatology, Volume 35, Issue 6, Page 595-604, December 2024.
Background – Mycobacterium cell wall fraction (MCWF) is derived from nonpathogenic Mycobacterium phlei and is used as an immunomodulatory compound in clinical practice, yet its mode‐of‐action requires further research. Objective – To evaluate the host response to MCWF in canine peripheral blood mononuclear cells (PBMCs) by using enzyme‐linked ...

Intracellular Mg2+ concentrations are differentially regulated in the sperm head and mid‐piece in acrosome reaction inducing conditions

open access: yesThe FASEB Journal, Volume 38, Issue 21, 15 November 2024.
Because Mg2+ complexes with ATP, changes in intracellular Mg2+ ([Mg2+]i), monitored with Mag‐520, reflect, in part, ATP levels. Mag‐520 allows the concomitant detection of [Mg2+]i and [Ca2+]i. [Mg2+]i increases under two conditions that reduce ATP: starvation and capacitation. Conversely, nutrient addition to starved sperm decrease Mag‐520 fluorescence.
