Auricular Non-Epithelial Tumors with Solar Elastosis in Cats: A Possible UV-Induced Pathogenesis

Veterinary Sciences, 2022
The photoinduced etiopathology of actinic keratosis and squamous cell carcinoma in feline species is well known. This etiology has also been reported for non-epithelial cutaneous tumors in other species.

Actinic Keratosis: Rationale and Management

Dermatology and Therapy, 2014
Actinic keratoses (AKs) are common skin lesions heralding an increased risk of developing squamous cell carcinoma (SCC) and other skin malignancies, arising principally due to excessive ultraviolet (UV) exposure. They are predominantly found in fair-skinned individuals, and increasingly, are a problem of the immunosuppressed.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Glucose‐Responsive and Analgesic Gel for Diabetic Subcutaneous Abscess Treatment by Simultaneously Boosting Photodynamic Therapy and Relieving Hypoxia

Advanced Science, EarlyView.
The work constructs a glucose‐triggered gel for diabetic abscess treatment. The results demonstrate that the gel catalyzes glucose into oxygen, alleviates the hypoxia, and ensures sufficient ROS generation to combat pathogenic bacteria. Simultaneously, borneol within the gel can enhance the antibacterial activity of ROS and alleviate pain in patients ...

Cold atmospheric plasma combined with nanoparticles in cancer therapy

Interdisciplinary Medicine, EarlyView.
Cold atmospheric plasma (CAP) generates a range of reactive oxygen and nitrogen species (RONS), including singlet oxygen (1O2), hydrogen peroxide (H2O2), hydroxyl radicals (·OH), nitrate (NO3− ${{\text{NO}}_{3}}^{-}$), and nitrite (NO2− ${{\text{NO}}_{2}}^{-}$), which induce oxidative stress and apoptosis in cancer cells.

Comparative histochemical study of Bowen’s disease and actinic keratosis: preserved normal basal cells in Bowen’s disease

European Journal of Histochemistry, 2009
The degree of DNA-instability as revealed by immunohistochemical staining with anti-cytidine antibody after acid hydrolysis (DNA-instability test) has been recently used as a marker of malignancy.

In Vivo Differentiation of Cutaneous Melanoma From Benign Nevi With Dual‐Modal System of Optical Coherence Tomography and Raman Spectroscopy

Journal of Biophotonics, EarlyView.
An innovative method for noninvasive melanoma diagnosis using the attenuation coefficient from OCT scans and machine learning has been proposed, supporting small sample sizes. When combined with Raman spectroscopy, it can further enhance accuracy. ABSTRACT A multimodal method comprising optical imaging using OCT and molecular detection using Raman ...

Capecitabine-induced activation of actinic keratosis: A common but underrecognized adverse event

Current Problems in Cancer: Case Reports, 2021
We report a case of a 70-year-old woman undergoing chemotherapy with capecitabine for breast cancer who presented with a diffuse erythematous facial eruption, consistent with actinic keratosis activation.

Estimation of the state of proliferative activity and expression of the oncomarker p53 in samples of actinic keratosis.

Морфологія, 2017
Background. Actinic keratosis is a precancerous condition of the skin, which most often occurs in the open areas of the skin (primarily, the head, neck and extremities) after prolonged or intense natural or artificial irradiation by ultraviolet rays in ...
