Self-affirmation intervention for patients newly diagnosed with advanced cancer: a preliminary efficacy trial.

Objective: Cancer diagnosis represents a life crisis. It remains unclear whether/what psychosocial intervention may enhance cancer patients' quality of life (QoL) during existential plight. This study aimed to examine preliminary efficacy of a brief writing intervention for patients newly diagnosed with advanced cancer with a focus on affirming personally important values and beliefs.

Long-Term Exposure to Tire-Derived 6-PPD Quinone Causes Neurotoxicity and Neuroinflammation via Inhibition of HTR2A in C57BL/6 Mice.

-(1,3-dimethylbutyl)-'-phenyl--phenylenediamine quinone (6-PPDQ), a novel contaminant derived from tire wear, has raised concerns due to its potential neurotoxicity, yet its long-term effects on mammalian neurological health remain poorly understood. This study investigates the neurotoxic and neuroinflammatory impacts of prolonged 6-PPDQ exposure using male C57BL/6 mice. Behavioral assessments revealed significant cognitive deficits, while biochemical analyses demonstrated increased levels of reactive oxygen species, apoptosis, and blood-brain barrier (BBB) disruption.

Tumor-Associated Macrophages Nano-Reprogrammers Induce "Gear Effect" to Empower Glioblastoma Immunotherapy.

Glioblastoma (GBM), the most malignant brain tumor with high prevalence, remains highly resistant to the existing immunotherapies due to the significant immunosuppression within tumor microenvironment (TME), predominantly manipulated by M2-phenotypic tumor-associated macrophages (M2-TAMs). Here in this work, an M2-TAMs targeted nano-reprogrammers, MG5-S-IMDQ, is established by decorating the mannose molecule as the targeting moiety as well as the toll-like receptor (TLR) 7/8 agonist, imidazoquinoline (IMDQ) on the dendrimeric nanoscaffold. MG5-S-IMDQ demonstrated an excellent capacity of penetrating the blood-brain barrier (BBB) as well as selectively targeting M2-TAMs in the GBM microenvironment, leading to a phenotype transformation and function restoration of TAMs shown as heightened phagocytic activity toward tumor cells, enhanced cytotoxic effects, and improved tumor antigen cross-presentation capability.

Neuronal TRPV1-CGRP axis regulates peripheral nerve regeneration through ERK/HIF-1 signaling pathway.

Severe trauma frequently leads to nerve damage. Peripheral nerves possess a degree of regenerative ability, and actively promoting their recovery can help restore the sensory and functional capacities of tissues. The neuropeptide calcitonin gene-related peptide (CGRP) is believed to regulate the repair of injured peripheral nerves, with neuronal transient receptor potential vanilloid type 1 (TRPV1) potentially serving as a crucial upstream factor.

Gaps in knowledge and management of iron deficiency in heart failure: a nationwide survey of cardiologists in China.

Background: Heart failure (HF) guidelines recommend routine testing for iron deficiency (ID) and, for those with ID, intravenous iron if the left ventricular ejection fraction is <50%. Guideline adherence to these recommendations by cardiologists in China is unknown.

Methods And Results: An independent academic web-based survey was designed and distributed via social networks to cardiologists across China.
