IMPORTANCE Long-term exposure to solar radiation produces deleterious photoaging of the skin. It is not known if diet can influence skin photoaging.OBJECTIVES To study the influence of a calorie-restricted diet and an obesity diet in mice exposed to long-term UV-B irradiation to assess if there is an association between diet and histopathological response to UV-B irradiation. DESIGN, SETTING, AND PARTICIPANTSIn this animal model study in an academic setting, the dorsal skin of SKH1 hairless mice receiving normal, calorie-restricted, and obesity diets was exposed to UV-B irradiation 3 times a week for 10 weeks and were compared with corresponding controls. The mice were placed in the following groups, with 8 animals in each group: (1) intact control (C) with regular diet and no UV-B exposure, (2) intact control with UV-B exposure (CR), (3) calorie-restricted diet (CrC), (4) calorie-restricted diet with UV-B exposure (CrR), (5) obesity diet (OC), and ( 6) obesity diet with UV-B exposure (OR). The experiment was conducted during October through December 2013. Tissue processing and histological analysis were completed in 2016.MAIN OUTCOMES AND MEASURES Histomorphometric analysis was performed on paraffin-embedded skin sections stained by histological and immunohistochemical methods for estimation of epidermal thickness, epidermal proliferating cell nuclear antigen index, collagen I, elastic fibers, fibroblasts, mast cells, dermal cellularity, and adipose layer ratio. Changes in wrinkles were noted. RESULTSHairless female mice (age range, 6-8 weeks) were obtained. With a normal diet, changes from UV-B irradiation occurred in epidermal thickness, epidermal proliferating cell nuclear antigen index, collagen I, elastic fibers, fibroblasts, and mast cells, which were modestly influenced by an obesity diet. Calorie restriction influenced the skin in nonirradiated control animals, with higher values for most variables. After UV-B exposure in animals with calorie restriction, epidermal thickness was increased, but other variables were unaffected. Animals receiving the calorie-restricted diet lost weight when exposed to long-term UV-B irradiation. Wrinkles were reduced in the calorie-restricted control group and in UV-B-exposed animals who received the obesity diet.CONCLUSIONS AND RELEVANCE Dietary alterations seem to modify histopathological responses to UV-B exposure in the skin of hairless mice.LEVEL OF EVIDENCE NA.

We conducted a comparative study of two oils extracted from Brachychiton populneus seeds and seed fibers grown in Tunisia. Oil yields from seed and seed fiber were 29.95 and 5.30%, respectively. GC-MS analysis showed that the most abundant fatty acid was linoleic acid (37.91%) followed by oleic acid (30.67%) in seeds. In seed fiber, the most abundant were oleic acid (62.04%) and linoleic acid (11.90%). Sterculic acid (7.27%), a rare fatty acid, was detected in seed oil. Moreover, carotenoid and chlorophyll levels were approximately two-fold higher in seed-fiber oil (39.66 and 1.9 mg/kg) than in seed oil (19.48 and 0.78 mg/kg). Tocol contents were more than 10-fold higher in fiber-seed oil (979.31 mg/100 g) than in seed oil (83.2 mg/100 g). Furthermore, thermal behavior (TGA and DSC) in both oils, and the antioxidant activity, phenolic content, and oxidative stability at different temperatures in seed oil were evaluated. The results of this study suggest that B. populneus seed oil may have an important role in nonfood applications and that seed-fiber oil is a source of high-value compounds.
