Examining the impact of corporate social advocacy (CSA) issue ownership and message content on authenticity perceptions and behavioral intentions

Holly Overton, Michail Vafeiadis, Pratiti Diddi et al. · 2025 · Corporate Communications An International Journal

Purpose As companies continue to engage in CSA, they continue to struggle with determining what issues they should speak out about and how they can create compelling messages that inspire action. Guided by arguments from issue ownership theory, this study examines CSA message content effects related to two different social-political issues on advocacy behavioral intentions, megaphoning, brand preference and purchase intention. Specifically, the level of advocacy in a CSA message is examined, as well as the manner in which the message is written (narrative vs informational). Furthermore, this s

18F-PI-2620 Tau PET is associated with cognitive and motor impairment in Lewy body disease

Joseph R. Winer, Hillary Vossler, Christina B. Young et al. · 2024 · Brain Communications

Abstract Co-pathology is frequent in Lewy body disease, which includes clinical diagnoses of both Parkinson’s disease and dementia with Lewy bodies. Measuring concomitant pathology in vivo can improve clinical and research diagnoses and prediction of cognitive trajectories. Tau PET imaging may serve a dual role in Lewy body disease by measuring cortical tau aggregation as well as assessing dopaminergic loss attributed to binding to neuromelanin within substantia nigra. We sought to characterize 18F-PI-2620, a next generation PET tracer, in individuals with Lewy body disease. We recruited 141 p

Unraveling the oral microbiome's role in Alzheimer's disease: From pathophysiology to therapeutic potential

Gilliana Rozenblum, Karima Ait‐Aissa, G. E. D. Zahran et al. · 2025 · Alzheimer s & Dementia

Oral dysbiosis contributes to Alzheimer's disease (AD) by promoting neuroinflammation. Pathobionts such as Porphyromonas gingivalis, Treponema denticola, and Fusobacterium nucleatum release virulence factors that induce amyloid beta aggregation and tau hyperphosphorylation, while the loss of commensals like Streptococcus salivarius and Neisseria spp. impairs anti-inflammatory protection, worsening neuronal damage. P. gingivalis is strongly linked to an increased risk of AD, especially in individuals with systemic conditions like diabetes, hypertension, and chronic kidney disease. Its presence

Cell Migration–Proliferation Dichotomy in Cancer: Biological Fact or Experimental Artefact?

Abdulaziz Alfahed · 2024 · Biology

The migration-proliferation dichotomy (MPD) has long been observed in cultured cancer cells. This phenomenon is not only relevant to tumour progression but may also have therapeutic significance in clinical cancer. However, MPD has rarely been investigated in primary cancer. This study aimed to either confirm or disprove the existence of MPD in primary cancer. Using primary gastric, colorectal and prostate cancer (GC, CRC and PCa) cohorts from the Cancer Genome Atlas and Memorial Sloan Kettering Cancer Center, this study interrogated the MPD phenomenon by utilising RNA-Seq-based proliferation

Population-scale sequencing resolves determinants of persistent EBV DNA

Sherry S. Y. Nyeo, Erin M. Cumming, Oliver S. Burren et al. · 2026 · Nature

Abstract Epstein–Barr virus (EBV) is an endemic herpesvirus implicated in autoimmunity, cancer and neurological disorders. Although primary infection is often subclinical, persistent EBV infection can drive immune dysregulation and long-term complications. Despite the ubiquity of infection, the determinants of EBV persistence following primary exposure remain poorly understood, although human genetic variation partially contributes to this phenotypic spectrum 1–3 . Here we demonstrate that existing whole genome sequencing (WGS) data of human populations can be used to quantify persistent EBV D

Similarities and differences between dog–human and human–human relationships

Borbála Turcsán, Dorottya Júlia Ujfalussy, Andrea Kerepesi et al. · 2025 · Scientific Reports

Most dog owners in Western countries regard their dogs as companions or family members, prompting extensive research on the human-animal bond. However, many studies rely on broad categories or single dimensions, such as satisfaction or attachment, which can oversimplify the complexity of these relationships. In contrast, our study employed a multifaceted approach, examining the dog-owner bond across 13 relationship scales and comparing these scales to four different types of human relationships to reveal the human-like roles of dogs within a family. Participants (N = 717) characterized their r

Therapeutic Potential of Short-Chain Fatty Acids in Gastrointestinal Diseases

Mengting Zhu, Jonathan Lee · 2025 · Nutraceuticals

Short-chain fatty acids (SCFAs) are metabolites derived from the fermentation of dietary fibre by gut bacteria. SCFAs function as essential regulators of host-microbiome interactions by participating in numerous physiological and pathological processes within the gastrointestinal (GI) tract. In recent years, the depletion of SCFAs has been increasingly linked to the pathogenesis of GI diseases. In this review, we summarize the current understanding of the therapeutic mechanisms of SCFAs in GI diseases, including inflammatory bowel disease, irritable bowel syndrome, metabolic dysfunction-associ

Neutrophil-initiated nociceptive ingrowth orchestrates inflammation resolution to potentiate bone regeneration

Xuanyu Qi, Guangzheng YANG, Zeqian Xu et al. · 2026 · Bone Research

Abstract Nociceptive pain is a cardinal feature of traumatic and inflammatory bone diseases. However, whether and how nociceptors actively regulate the immune response during bone regeneration remains unclear. Here, we found that neutrophil-triggered nociceptive ingrowth functioned as negative feedback regulation to inflammation during bone healing. A unique Il4ra + Ccl2 high neutrophil subset drove intense postinjury TRPV1 + nociceptive ingrowth, which in return dissipated inflammation by activating the production of pro-resolving mediator lipoxin A4 (LXA4) in osteoblasts. Mechanistically, os

Vitamin D and Chronic Disorders: A Review of Metabolic and Cardiovascular Diseases

Ewelina Młynarska, Wiktoria Lisińska, Katarzyna Hossa et al. · 2025 · Pharmaceuticals

Vitamin D, long recognized for its essential role in calcium-phosphate balance and bone health, has increasingly been identified as a pleiotropic regulator of metabolic, cardiovascular, and renal function. Deficiency of vitamin D is widespread worldwide and has been linked to a higher risk of insulin resistance, type 2 diabetes, atherosclerosis, hypertension, and chronic kidney disease. Meta-analyses suggest that each 10 nmol/L (≈4 ng/mL) increase in serum 25-hydroxyvitamin D [25(OH)D] is associated with about a 4% lower risk of type 2 diabetes, whereas other analyses indicate an approximately

The myth of the Bayesian brain

Madhur Mangalam · 2025 · European Journal of Applied Physiology

The Bayesian brain hypothesis-the idea that neural systems implement or approximate Bayesian inference-has become a dominant framework in cognitive neuroscience over the past two decades. While mathematically elegant and conceptually unifying, this paper argues that the hypothesis occupies an ambiguous territory between useful metaphor and testable, biologically plausible mechanistic explanation. We critically examine the key claims of the Bayesian brain hypothesis, highlighting issues of unfalsifiability, biological implausibility, and inconsistent empirical support.

Why Is Clozapine Uniquely Effective in Treatment-Resistant Schizophrenia? A Review and Proposal

Robin Murray, Alice Egerton, Yueming Gao et al. · 2025 · Biological Psychiatry

Much is known about the use, benefits, and side-effects, of clozapine in treatment resistant schizophrenia (TRS). However, why clozapine is more effective than other antipsychotics in TRS remains unclear. This paper addresses this question. TRS patients show glutamate abnormalities, and clozapine has widespread effects on glutamate. However, these actions have not been proven different to those of other antipsychotics. Immune dysfunction is also reported in TRS, and clozapine has anti-inflammatory actions, but these have not been correlated with clinical improvement. Currently, there is much i
