The receptor for advanced glycation end-products (RAGE), a member of the immunoglobulin superfamily, is expressed in various cell types and mediates cellular responses to a wide range of ligands. The activation of RAGE triggers complex signaling pathways that drive inflammatory, oxidative, and proliferative responses, which are increasingly implicated in the pathogenesis of skin diseases. Despite its well-established roles in conditions such as diabetes, cancer, and chronic inflammation, the contribution of RAGE to skin pathologies remains underexplored.

Importance: Moderate to severe atopic dermatitis (AD) is a chronic inflammatory skin disease that often requires continuous long-term systemic management. Long-term safety and efficacy data for treatment options are critically important.
Objective: To assess the safety and efficacy of dupilumab treatment for up to 5 years in adults with moderate to severe AD.
Background: Moderate-to-severe atopic dermatitis (AD) often requires long-term management with systemic therapies.
Objective: Our objective was to report the safety and efficacy of dupilumab treatment up to 4 years in adults with moderate-to-severe AD and efficacy in a subgroup of patients who transitioned from dupilumab once-weekly (qw) to administration every other week (q2w).
Methods: This interim analysis of the open-label extension study (NCT01949311) evaluated dupilumab 300 mg qw or q2w in adults previously enrolled in dupilumab trials for moderate-to-severe AD.
Melanoma is a life-threatening disease due to the early onset of metastasis and frequent resistance to the applied treatment. For now, no single histological, immunohistochemical or serological biomarker was able to provide a precise predictive value for the aggressive behavior in melanoma patients. Thus, the search for quantifying methods allowing a simultaneous diagnosis and prognosis of melanoma patients is highly desirable.

In this paper, we describe a novel, non-enzymatic and effective method of skin melanocyte and metastatic melanoma cell isolation and culture (along with the spontaneous spheroid creation) from skin or lymph node explants. The method is based on the selective harvesting of melanocytes and melanoma cells emigrating from the cultured explants.

Before creating wounds on the backs of 24 Sprague-Dawley rats, intradermal injections were made. Lidocaine-epinephrin solutions were supplemented with 0.

Objective: To investigate the efficacy and safety of oral abrocitinib plus topical therapy in adolescents with moderate-to-severe AD.
Design, Setting, And Participants: The phase 3, randomized, double-blind, placebo-controlled study JADE TEEN was conducted in countries of the Asia-Pacific region, Europe, and North America in patients aged 12 to 17 years with moderate-to-severe AD and an inadequate response to 4 consecutive weeks or longer of topical medication or a need for systemic therapy for AD.
The aim of the study was to evaluate if a pre-incisional -acetylcysteine (NAC) treatment altered the process of wound healing in a rat model. The dorsal skin of 24 Sprague-Dawley rats was incised in six locations. Before the incisions were made, skin was injected either with lidocaine and epinephrine (one side) or with these agents supplemented with 0.

View Article and Find Full Text PDFFocal cortical dysplasia (FCD) is one of the most important causes of drug-resistant epilepsy in paediatric patients, particularly in those below the age of 3. Even though over 40 years have passed since the first description of the entity by Taylor, the exact mechanisms causing these cortical abnormalities remain unelucidated. In this review, we summarise the current knowledge on clinical and histopathological aspects, taking into account the new classification system proposed by the International League Against Epilepsy.

Bone tissue was found in 26 kidneys out of 100 injected with whole bone marrow cells suspension. Cultured stromal bone marrow cells grafted into kidney parenchyma produced ossicles in only 4 out of 101 injected kidneys.

Because of the potential risk of the presence of pathogenic prions in bovine collagen, part of collagen dressings is formed on the basis of porcine collagen. Currently, a least of an immunogenic form of collagen is atelocollagen, which is subjected to enzyme-treated collagen, in which the terminal amino acids are removed from the collagen.

The aim of the present study was to verify those findings in experiments, in vitro, in melanoma cell line, and in vivo, in mice. The expression of tyrosinase in B16F10 melanoma cell line, after induction of melanogenesis by UVB irradiation, was examined by Western blot analysis.

The yield of induced bone does not critically depend on the mass of implanted matrices, and thus on the quantity of bone morphogenetic proteins (BMPs) present in the implants. A positive correlation between bone matrix implant weight and the yield of induced bone was observed only 28 days post grafting, i.
