Compelling evidence has demonstrated that rehabilitation through physical exercise, a non-invasive and non-surgical intervention, enhances muscle reinnervation and motor recovery after peripheral nerve injury (PNI) by increasing muscle-derived brain-derived neurotrophic factor (BDNF) expression and triggering TrkB-dependent axonal plasticity. Adenosine has been widely acknowledged to trigger TrkB via A2A receptor (A2AR). Since motor nerve terminals co-express TrkBs and A2ARs and depolarizing conditions increase muscle release of BDNF and adenosine, we examined whether A2ARs activation could recapitulate the functional recovery benefits of intermittent exercise after a nerve crush.

Research on the cerebellum and its functional organization has significantly expanded over the last decades, expanding our comprehension of its role far beyond motor control, including critical contributions to cognition and affective processing. Notably, the cerebellar lateralization mirrors contralateral brain lateralization, a complex phenomenon that remains unexplored, especially across different stages of life. The present work aims to bridge this gap by providing a comprehensive scoping review of the lateralization of motor, cognitive, and affective functioning within the cerebellum across the lifespan.

Advancing paleoanthropology beyond default nulls.

Behav Brain Sci

January 2025

Department of Philosophy, University of California, Santa Barbara, CA,

While we are sympathetic with Stibbard-Hawkes' approach, we disagree with the proposal to switch to a "cognitively modern" null for all species. We argue in favor of a more evidence-driven approach, inspired by recent debates in comparative cognition. Ultimately, parsing the contributions of different genetic and extra-genetic factors in human evolution is more promising than setting a priori nulls.

Article Synopsis
  • Selective binding and optical sensing of Zn(II) and Cd(II) in water were studied using different receptors (L1, HL2, L3, HL4, HL5) to see how complex stability affects metal signaling.
  • The receptors all have a cyclic tetra-amine structure combined with either one or two quinoline or 8-hydroxyquinoline units, influencing their properties and interactions.
  • The study showed that Zn(II) forms more stable complexes with some receptors, while Cd(II) complexes benefit from better fitting in specific cavities, leading to unique optical behaviors for each metal in their respective complexes.

Introduction: Alongside sarcopenia, the age-related loss of muscle strength and power, known as dynapenia, increases the risk of functional disability and mortality in older adults. However, engaging in sporting activities during old age appears to enhance functional capacity. The differences in effects between athletes and sedentary individuals, as well as between genders, have yet to be fully clarified.

Giese-type alkylation of dehydroalanine derivatives via silane-mediated alkyl bromide activation.

Beilstein J Org Chem

December 2024

Department of Chemical and Geological Sciences, University of Cagliari, S.S. 554, bivio per Sestu, 09042 Monserrato (CA), Italy.

The rising popularity of bioconjugate therapeutics has led to growing interest in late-stage functionalization (LSF) of peptide scaffolds. α,β-Unsaturated amino acids like dehydroalanine (Dha) derivatives have emerged as particularly useful structures, as the electron-deficient olefin moiety can engage in late-stage functionalization reactions, like a Giese-type reaction. Cheap and widely available building blocks like organohalides can be converted into alkyl radicals by means of photoinduced silane-mediated halogen-atom transfer (XAT) to offer a mild and straightforward methodology of alkylation.

This study focused on the interplay between NADPH oxidase 2 (NOX 2) activation and mitochondrial superoxide (mitoO) formation induced by clinically relevant concentrations of arsenic trioxide (ATO; AsO) in acute promyelocytic leukemia (APL) cells. Carefully controlled inhibitor studies and small interfering RNA mediated downregulation of p47 (a component of the NOX 2 complex) expression demonstrated that, in an APL cell line, ATO promotes upstream NOX 2 activation critically connected with the formation of mitoO and with the ensuing mitochondrial permeability transition (MPT)-dependent apoptosis. Instead, acute myeloid leukemia (AML) cell lines respond to ATO with low NOX 2 activation, resulting in a state that is non-permissive for mitoO formation.

Gut microbiota analysis, until a few years ago an exclusive research tool, has recently begun to spread among doctors and nutritionists around the world as a means aimed at better understanding patient disorders. As often happens, the commercial push has literally exploded and today there are numerous companies that offer microbiota analysis of dubious quality and/or as a business appliance aimed at selling supplements and the like. For non-experts it can therefore be difficult to find one's way among the numerous proposals.

Background: standardised extracts, characterised by the presence of hydroxycinnamic acids, have been experimentally demonstrated to be endowed with anti-anxiety and anti-insomnia pharmacological actions. These effects, probably attributable, at least in part, to the role played by rosmarinic acid on GABA-T, have not always been observed in a reproducible manner in humans, perhaps due to the poor bioavailability of these compounds.

Methods: as nutraceuticals and botanicals could be an alternative option to prescription medications for alleviating symptoms of mild anxiety and insomnia, we have verified in a prospective, double-blind, placebo-controlled, and cross-over study the supporting role on sleep quality played by a highly standardised extract, formulated as Phytosome™ (MOP) to improve the oral bioavailability of its active polyphenolic components.

Cannabidiol has been shown to ameliorate neuropathic pain and its affective components. Previous studies highlighted the pharmacological interaction between the CBD and opioid system, particularly the MOR, but the understanding of the interaction between CBD and kappa opioid receptor (KOR), physiologically stimulated by the endogenous opioid dynorphin, remains elusive. We assessed the pharmacological interactions between CBD and nor-BNI, a selective KOR antagonist in a rat neuropathic pain model.
