The skin hydration level is a key factor that influences the physical and mechanical properties of the skin. The stratum corneum (SC), the outermost layer of the epidermis, is responsible for the skin's barrier function. In this study, we investigated the role of a unique composition of extract for its ability to activate CD44, a cell-surface receptor of hyaluronic acid, and aquaporin-3, a water-transporting protein, in human keratinocytes (HaCaT).

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.
Objectives: The study aimed to evaluate the use of oral exfoliative cytology and highlight its limited effectiveness in diagnosing oral diseases.
Materials And Methods: A total of 1000 consecutive cases of oral cytology were retrieved from the files of an Oral Pathology Service, comprising the period between January 2002 and December 2022. Patient data and clinical details of the lesions were collected, and all slides were reviewed.
As SARS-CoV-2 continues to evolve and herd immunity establishes, an increasing number of asymptomatic infections have been reported, increasing the risk of airborne spread of the virus. Most of the studies regarding SARS-CoV-2 RNA presence in air refer to indoor environments, with few studies having reported SARS-CoV-2 RNA in outdoor air. The aim of this study was to assess the presence of SARS-CoV-2 RNA at two different settings, crowded outdoor versus empty outdoor environments in Valladolid, Spain, during winter 2021.
