Article Synopsis
- - The study aimed to compare the fractal dimension (FD) and lacunarity of mandibular bone in patients with osteoradionecrosis (ORN) versus those without, using digital panoramic radiographs and ImageJ software for analysis.
- - A total of 25 patients were divided into two groups (14 with ORN and 11 without), and while FD and lacunarity values were similar across groups, certain thresholds were identified that helped differentiate between the two populations.
- - Although the differences in FD and lacunarity were not statistically significant, the effect sizes suggest potential clinical relevance, indicating that these measurements could be useful in evaluating bone health post-radiotherapy.
There is an interaction between dendrocytes and mast cells in the skin. However, in elastosis-related diseases such as actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC), this interaction remains unknown. We investigated the presence of intact and degranulated mast cells in AC and LLSCC.

Prolonged hyperglycemia conditions are a risk factor for chronic degenerative diseases such as diabetes and obesity. Testosterone is known to cause muscle hypertrophy, reduced fat mass, and increased body strength. The study aimed to verify possible alterations and differences in the influence of testosterone on the physical performance in post-exercise conditions of young and old animals with alloxan-induced hyperglycemia.

- Five new lignanamides and ten known amides were extracted from the roots' chloroform extract, with new compounds identified through NMR and mass spectrometry.
- The absolute configuration of one compound was determined using ECD experiments and quantum mechanical calculations.
- The anti-inflammatory effects of these compounds were tested on macrophages, showing that all reduced nitric oxide levels, while one compound did not significantly affect IL-10 levels, indicating potential anti-inflammatory properties.

Article Synopsis
- - The study aimed to review the impact of non-surgical periodontal treatment on rheumatoid arthritis symptoms, specifically looking at the 28-joint Disease Activity Score (DAS28) and inflammatory markers like C-reactive protein and erythrocyte sedimentation rate, from existing systematic reviews.
- - Researchers conducted thorough electronic searches for relevant studies up to August 2024, including 10 systematic reviews (six with meta-analyses), which collectively examined data before and after the treatment.
- - Findings indicated that non-surgical periodontal treatment significantly reduced levels of C-reactive protein, erythrocyte sedimentation rate, and DAS28 in individuals with rheumatoid arthritis, with a notable reduction in DAS28 observed after three months. *
