This study investigated the prevalence and impact of auditory agnosia for environmental sounds in individuals with Alzheimer’s disease (AD), finding that over half exhibited signs of this central auditory dysfunction along with a high rate of unrecognized peripheral hearing loss. Although these factors appeared independent and showed limited direct effect on measured quality of life, possibly due to sheltered living environments and lack of patient awareness, they jointly contribute to daily functional decline, highlighting the importance of early hearing assessment and intervention in AD management.

The article discusses the critical role of the mitochondrial contact site and cristae organizing system (MICOS) complex in the pathogenesis of Alzheimer's disease (AD). It highlights how MICOS abnormalities, including subunit dysfunction and interactions with disease-associated proteins, to hallmark AD pathologies such as amyloid-β accumulation, neurofibrillary tangle formation, and neuronal apoptosis. The article suggests that targeting MICOS subunits with pharmacological interventions may provide novel therapeutic insights for AD treatment.

The article discusses the need for and challenges of developing combination therapies for Alzheimer's disease, given the complex and multifactorial nature of the disease. As of 2024, there were 21 combination trials in the pipeline, primarily involving repurposed agents targeting processes like inflammation, senescence, and amyloid-tau interactions. Key challenges include distinguishing individual drug effects and managing the operational complexity of combination trials.f

This study identified the gene PpNLR1 and its promoter variation as key factors conferring green peach aphid (GPA) resistance in peach, regulated by jasmonate-induced transcription factor PpERF109. Additionally, GPA salivary effectors activate the peach immune response through PpNLR1, offering valuable insights for breeding aphid-resistant peach cultivars.
