A mathematical model, which describes the dynamics of acutely irradiated skin epidermal epithelium in swine, is developed. This model embodies the key mechanisms of regulation of skin epidermal epithelium and the principal stages of development of its cells (basal, prickle, and corneal). The model is implemented as a system of nonlinear ordinary differential equations, whose variables and parameters have clear biological meaning. The modeling results for the dose- and time-dependent changes in basal and prickle cell populations are in a good agreement with relevant experimental data. The correlation between the experimental data on the dynamics of moist reaction in acutely irradiated swine skin epidermal epithelium and the corresponding modeling results on the dynamics of corneal cells is revealed. Proceeding from this, the threshold level of corneal cells, which indicates the appearance of the moist reaction, is found. All this bears witness to the validity of employment of the developed model, after appropriate identification, in the investigation and prediction of radiation effects on skin epidermal epithelium in humans.

Nevus sebaceous (NS) is a congenital hamartoma characterized by the presence of skin structures, including the epidermis, sebaceous glands, and hair follicles. NS predominantly occurs on the scalp and has the potential to give rise to secondary tumors, with a small proportion being malignant; the most frequently observed malignant tumor associated with NS is basal cell carcinoma. In this report, we retrospectively present four cases of sebaceous nevus on the scalp complicated by basal cell carcinoma.

Epidermal growth factor receptor inhibitors (EGFRI) are biological factors used in several types of cancer, including non-small-cell lung cancers (NSCLC). One of the EGFR inhibitors that has been approved for NSCLC is afatinib. Dermatologic adverse events are the most commonly reported and may impair the patient's compliance to the therapy as it causes aesthetic discomfort and significantly impact the patient's quality of life.

In alignment with the global movement toward reducing animal testing, several reconstructed human epidermis (RHE) models have been created for conducting skin irritation tests. These models have undergone development, verification, validation, and integration into OECD TG 439. Our team has introduced a novel in-house RHE named GB-RHE, and we adhere to OECD TG 439 to pre-validate the model and test its potential employment for nanoparticle irritation studies.

Desmosomes are adhesive cell contacts abundant in tissues exposed to mechanical strain, such as the stratified and simple epithelia of the epidermis and mucous membranes, as well as the myocardium. Besides their role in mechanical cell cohesion, desmosomes also modulate pathways important for tissue differentiation, wound healing and immune responses. Dysfunctional desmosomes, resulting from pathogenic variants in genes encoding desmosomal components, autoantibodies targeting desmosomal adhesion molecules or inflammation, cause the life-threatening diseases arrhythmogenic cardiomyopathy and pemphigus and contribute to the pathogenesis of inflammatory bowel diseases.

Background: There is no definitive solution for the treatment of striae distensae (SD), and effectiveness of each treatment method remains controversial. We aimed to investigate and compare the efficacy of the combination of Erbium YAG (Er:YAG) laser and stromal vascular fraction (SVF), the combination of Er:YAG laser and platelet-rich plasma (PRP) and Er:YAG laser plus saline in the treatment of SD.
Materials And Methods: In 12 participating patients with at least three lesions (36 lesions in total), each lesion was treated with an Er:YAG laser.
