Abstract
High efficacy and minimal toxicity radioprotectors are desirable options for the hazards posed by nuclear medical and energy technologies and the dangers presented by nuclear weapons in an unstable global situation. Although cysteamine is an effective radioprotector, it has considerable toxicity. In this study, the protective effects of the less toxic organosulfur compounds 2-aminoethylthiosulfate (AETS), thiotaurine (TTAU), and hypotaurine (HTAU) against X-ray damage in mice were compared with that of cysteamine. Intraperitoneal injection of either AETS or cysteamine (2.2 mmol/kg body weight) 30 min before X-ray irradiation (7.0 Gy) provided 100% survival for 30 days, limited the decrease in erythrocytes and neutrophils over 9 days, and reduced damage to bone marrow and spleen over 9 days. Neither TTAU nor HTAU provided any protection. In mice, 30 min after AETS administration, non-protein thiol content increased in the spleen, indicating cysteamine generation by AETS hydrolysis, the active protective species of AETS. All examined compounds scavenged •OH under diffusion control in aqueous solution, which is inconsistent with the difference in the protective effects among the compounds. The results indicate that AETS protects animals from ionizing radiation by several mechanisms, including scavenging •OH as cysteamine.

Abstract
BACKGROUND Effective anti-aging treatments are an unmet consumer need. AIM Ex vivoand clinical tests have evaluated the efficacy of a topical facial serum containing a proprietary blend of neuropeptides, proteins, amino acids, and marine extracts on aged skin. METHODS In the ex vivo study the facial serum was compared to a commercially marketed face serum and to an untreated control on skin explants using microrelief, smoothness, and epidermal thickness endpoints. The 12 weeks monadic clinical study was designed for the test product to be used on the whole face. Subjects functioned as their own control; evaluating change from baseline. Skin was evaluated clinically by a Dermatologist for tolerability and for efficacy. Also part of the product assessment was skin hydration measurements, imaging, and a subject questionnaire. RESULTS The facial serum improved skin condition by significant reductions in skin surface area occupied by microfolds and in skin roughness. Additionally, it increased epidermal thickness as compared to the untreated control as well as the commercially marketed face serum. The facial serum provided a statistically increased skin moisturization compared to pretreatment values. Dermatological evaluation of the skin concluded that there were statistically and clinically significant improvements in skin smoothness, wrinkles severity, fine lines visibility and lifting, and tightening effects at crow's feet area, forehead, and upper lip. CONCLUSION A facial serum, containing a proprietary blend of neuropeptides, proteins, amino acids, and marine extracts, has been shown to improve the overall quality of aged skin in a series of ex vivo and clinical tests.

Non-melanoma skin cancers: physio-pathology and role of lipid delivery systems in new chemotherapeutic treatments. Neoplasia 2022; 30:100810. [PMID: 35649306 PMCID: PMC9160356 DOI: 10.1016/j.neo.2022.100810] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 05/16/2022] [Indexed: 12/19/2022]
Abstract
Non-melanoma carcinoma has high incidence rates and has two most common subtypes: basal cell carcinoma and squamous cell carcinoma. This type of carcinoma is usually not fatal; however, it can destroy sensory organs such as the nose, ears, and lips. The treatment of these injuries using non-invasive methods is thus strongly recommended. Some treatments for non-melanoma carcinoma are already well defined, such as surgery, cryosurgery, curettage and electrode section, and radiotherapy; however, these conventional treatments cause inflammation and scarring. In the non-surgical treatment of non-melanoma carcinoma, the topical administration of chemotherapeutic drugs contributes for an effective treatment with reduced side effects. However, the penetration of anticancer drugs in the deeper layers of the skin is required. Lipid delivery systems (liposomes, solid lipid nanoparticles, nanostructured lipid carriers) have been developed to overcome epidermal barrier of the skin and to allow the drugs to reach tumor cells. These lipid nanoparticles contribute to control the release profile of the loaded chemotherapeutic drugs, maintaining their stability and increasing death of tumor cells. In this review, the characteristics of non-melanoma carcinoma will be discussed, describing the main existing treatments, together with the contribution of lipid delivery systems as an innovative approach to increase the effectiveness of topical therapies for non-melanoma carcinomas.
