Objectives: To examine the histopathological characteristics of inflammatory lesions containing Actinomyces based on DNA sequencing. Furthermore, case reports of actinomycosis in the maxillofacial region are summarized by a review of the literature.
Study Design: The study comprised 12 cases of inflammatory lesions containing Actinomyces as diagnosed by DNA analysis. The average age of the subjects was 59 ± 15 years (6 males; 6 females).
Results: The distribution of causative bacteria was: Actinomyces israelii in 9 cases, Actinomyces gerencseriae in 2 cases, and Actinomyces naeslundii in 1 case. Four cases diagnosed by DNA sequencing were positive for "Druse," a known morphological diagnostic characteristic of actinomycosis, and 8 cases lacked typical colony formation.
Conclusions: DNA analysis using paraffin-embedded samples is effective for both early and accurate diagnosis of oral lesions containing Actinomyces.

Atherosclerosis (AS) is a prevalent inflammatory vascular disease characterized by plaque formation, primarily composed of foam cells laden with lipids. Despite lipid-lowering therapies, effective plaque clearance remains challenging due to the overexpression of the CD47 molecule on apoptotic foam cells, inhibiting macrophage-mediated cellular efferocytosis and plaque resolution. Moreover, AS lesions are often associated with severe inflammation and oxidative stress, exacerbating disease progression.

Background: BDNF has increasingly gained attention as a key molecule controlling remyelination with a prominent role in neuroplasticity and neuroprotection. Still, it remains unclear how BDNF relates to clinicoradiological characteristics particularly at the early stage of the disease where precise prognosis for the further MS course is crucial.
Methods: BDNF, NfL and GFAP concentrations in serum and CSF were assessed in 106 treatment naïve patients with MS (pwMS) as well as 73 patients with other inflammatory/non-inflammatory neurological or somatoform disorders using a single molecule array HD-1 analyser.

The differentiation between benign and malignant brain lesions remains a fundamental challenge in modern neuroimaging. This case highlights a rare presentation of ectatic Virchow-Robin spaces (VRS), which mimicked tumefactive brain lesions and required a comprehensive diagnostic evaluation to exclude neoplastic, infectious, and inflammatory processes. A 37-year-old female presented with progressive headache, cognitive impairment, and facial pain.

Currently, most peripheral nerve injuries are incurable mainly due to excessive reactive oxygen species (ROS) generation in inflammatory tissues, which can further exacerbate localized tissue injury and cause chronic diseases. Although promising for promoting nerve regeneration, stem cell therapy still suffers from abundant intrinsic limitations, mainly including excessive ROS in lesions and inefficient production of growth factors (GFs). Biomaterials that scavenge endogenous ROS and promote GFs secretion might overcome such limitations and thus are being increasingly investigated.
