Protocol for a feasibility study evaluating a supported self-management intervention for stroke survivors with aphasia (StarStep study).
Pilot Feasibility Stud
January 2025
Academic Unit for Ageing and Stroke Research, Leeds Institute of Health Sciences, University of Leeds, Leeds, LS2 9JT, UK.
Background: There is a growing evidence base to support the use of self-management interventions for improving quality of life after stroke. However, stroke survivors with aphasia have been underrepresented in research to date. It is therefore unclear if self-management is an appropriate or effective approach for this group.

Background: Normal brain aging is associated with dopamine decline, which has been linked to age-related cognitive decline. Factors underlying individual differences in dopamine integrity at older ages remain, however, unclear. Here we aimed at investigating: (i) whether inflammation is associated with levels and 5-year changes of in vivo dopamine D2-receptor (DRD2) availability, (ii) if DRD2-inflammation associations differ between men and women, and (iii) whether inflammation and cerebral small-vessel disease (white-matter lesions) serve as two independent predictors of DRD2 availability.

Due to their anatomic proximity, the 2 cancers have both different but also shared risk factors and epidemiological features.

Epigenetics Chromatin
January 2025
Department of Neurology, Tongji Shanxi Hospital, Shanxi Bethune Hospital, Shanxi Academy of Medical Sciences, Third Hospital of Shanxi Medical University, Taiyuan, China.
Background: The DNA methylation-based epigenetic clocks are increasingly recognized for their precision in predicting aging and its health implications. Although prior research has identified connections between accelerated epigenetic aging and multiple sclerosis, the chronological and causative aspects of these relationships are yet to be elucidated. Our research seeks to clarify these potential causal links through a bidirectional Mendelian randomization study.

BMC Oral Health
January 2025
Shiraz Institute for Cancer Research, School of Medicine, Shiraz University of Medical Sciences, P.O. Box 71345-3119, Shiraz, Iran.
Background: This investigation sought to evaluate cytotoxic and genotoxic effects of two different types of orthodontic bands after aging in acidic and neutral artificial saliva using human gingival fibroblast-like (HGF1-PI 1) cell lines.
Methods: Two commercial brands of orthodontic molar bands (American orthodontic (AO) and 3 S-dental bands), commonly used by orthodontists, were tested. These bands were divided into four groups to examine the effects of aging following thermocycling, and pH variations (pH = 4.
