Context: Atherosclerosis affects large and medium caliber arteries by forming calcific atheromas, precursors of cerebral vascular disease. Diabetes mellitus, obesity, and hypertension are considered as risk factors of atherosclerosis. Panoramic radiographs can display images suggestive of carotid artery calcifications (CACs).
Aims: To investigate the prevalence of images suggestive of CAC in panoramic radiographs of the jaws (PRJs) and confirm them by Doppler ultrasonography. To evaluate their anatomic locations and relationships between systemic conditions (diabetes, hypertension, and obesity) and the presence of unilateral or bilateral CAC detected on PRJ or by Doppler ultrasonography.
Materials And Methods: Of the 723 routinely performed PRJ in patients over 40 years at the Radiology Center in São Luís, Maranhão, Brazil, 21 PRJ containing images suggestive of CAC were selected in this cross-sectional study. The findings from the PRJ were confirmed by Doppler sonography.
Results: Images suggestive of CAC was detected in 21 (2.9%) of the PRJ evaluated, consisting of 11 (52.4%) hypertensive, 7 (33.3%) diabetics, and 9 (42.9%) obese. There was a higher prevalence of hypertensive patients in the unilateral CAC group (100%) and bilateral CAC (60%) compared to patients without CAC (25%).
Conclusions: CACs can be detected in PRJs, and are more frequent in common carotid arteries. No significant associations were detected between the presence of unilateral or bilateral CAC in PRJ and hypertension, diabetes, or obesity.

Disentangling the neural underpinnings of response inhibition in disruptive behavior and co-occurring ADHD.
Eur Child Adolesc Psychiatry
January 2025
Department of Child and Adolescent Psychiatry, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands.
While impaired response inhibition has been reported in attention-deficit/hyperactivity disorder (ADHD), findings in disruptive behavior disorders (DBDs) have been inconsistent, probably due to unaccounted effects of co-occurring ADHD in DBD. This study investigated the associations of behavioral and neural correlates of response inhibition with DBD and ADHD symptom severity, covarying for each other in a dimensional approach. Functional magnetic resonance imaging data were available for 35 children and adolescents with DBDs (8-18 years old, 19 males), and 31 age-matched unaffected controls (18 males) while performing a performance-adjusted stop-signal task.

The abnormally viscous and thick mucus is a hallmark of cystic fibrosis (CF). How the mutated CF gene causes abnormal mucus remains an unanswered question of paramount interest. Mucus is produced by the hydration of gel-forming mucin macromolecules that are stored in intracellular granules prior to release.

Background: Magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy of ventral intermediate (Vim) nucleus is useful to treat drug-resistant tremor-dominant Parkinson's disease (TdPD), but tremor relapse may occur. Predictors of relapse have been poorly investigated so far.
Objective: The aim of this study is to evaluate the role of clinico-demographic, procedural, and neuroradiological variables in determining clinical response, relapse, and adverse events (AEs) in TdPD after MRgFUS Vim-thalamotomy.
Circulating Tumor DNA Detection for Recurrence Monitoring of Stage I Non-Small Cell Lung Cancer Treated With Microwave Ablation.

Department of Minimally Invasive Tumor Therapies Center, Beijing Hospital, National Center of Gerontology, Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, Beijing, China.
Purpose: As microwave ablation continues to be used in patients with inoperable stage I non-small cell lung cancer (NSCLC), it is particularly important to monitor efficacy. Whether plasma ctDNA detection can predict its efficacy should be illustrated.
Methods: We recruited 43 patients with inoperative stage I NSCLC, all of whom underwent biopsy-synchronous microwave ablation (MWA).
Unsaturated Fatty Acids Are Decreased in Aβ Plaques in Alzheimer's Disease.

Center for Protein Diagnostics (PRODI) Biospectroscopy, Ruhr University Bochum, Bochum, Germany.
Alzheimer's disease (AD) is characterized by the accumulation of amyloid-beta (Aβ) plaques in the brain, contributing to neurodegeneration. This study investigates lipid alterations within these plaques using a novel, label-free, multimodal approach. Combining infrared (IR) imaging, machine learning, laser microdissection (LMD), and flow injection analysis mass spectrometry (FIA-MS), we provide the first comprehensive lipidomic analysis of chemically unaltered Aβ plaques in post-mortem human AD brain tissue.
