Adjuvante dermatokosmetische Aknetherapie
2010
Adjuvant dermato-cosmetic therapy in acne is an essential part of the concept of treating acne after initiation and during maintenance therapy. Those are mechanical peeling, chemical peeling and its combination. It needs supervision by an experienced dermatologist.
Numerical simulations demonstrate that the double tapering of the spatualae of lizards and insects maximize both detachment resistance and stability
2011
Many biological attachment devices of insects, spiders and geckos consist of arrays of hairs (setae), which are terminated by contact elements of different shapes. However, the most frequently observed shape is a thin plate-like spatula. In spite of a rather wide range of sizes, most spatulae of different animals are not uniform, but rather possess a gradient in thickness and width. Here we show that the spatulae of insects and geckos become gradually thinner and wider approaching the end. This geometrical effect is explained in the present paper, by using a numerical approach for the modelling of the van der Waals adhesion and friction between the contact elements and the substrate. The ap…
Estimation of selected skin parameters during a series of beauty treatments in women with acne: a pilot study
2021
Background: Acne vulgaris occurs most often in young people and can significantly decrease the quality of life. Properly selected dermatological therapy and cosmetic procedures can effectively improve the skin condition of acne patients. Aim of the study: The aim of this study was to examine how various cosmetics treatments affect facial sebum levels, skin hydration, and desquamation in young women with acne vulgaris. Material and Methods: 101 women with acne aged 19–29 (M = 22.5 years, SD = 2.3 years) were included in the study. The following cosmetic treatments were used over a 12-week period: intensive pulsing light, alpha-hydroxy acids, cavitation peeling, non-needle mesotherapy, diamon…
Ruolo della variazione di larghezza e di spessore nelle spatole delle lucertole e degli insetti
2012
Molti dispositivi biologici di adesione degli insetti, dei ragni e dei gechi consistono di matrici di peli (setae) che terminano con elementi di contatto di diverse forme. Tuttavia, la forma più osservata è una spatola appiattita. Nonostante nei diversi animali le spatole esistano in una notevole varietà di dimensioni, la maggior parte di esse non sono uniformi ma posseggono un gradiente sia in spessore che in larghezza. In questo lavoro investighiamo perché le spatole dei gechi diventano gradualmente più sottili e più larghe avvicinandosi alla loro estremità. Il motivo di questa particolare geometria è studiato utilizzando un approccio numerico basato sul metodo degli elementi finiti. La m…
Acanthosis nigricans: A review.
2020
Background Acanthosis nigricans (AN) is a cutaneous disorder characterized by symmetric velvety hyperpigmented plaques on intertriginous areas like axilla, neck, inframammary, and groin. Aims To summarize the pathophysiology and classification of AN, provide an update of diagnostic testing strategies, and describe the current therapeutic options described so far in the literature for this disease. Methods A comprehensive english language literature search across multiple databases (PubMed, EMBASE, MEDLINE, and Cochrane) for keywords (alone and in combination) was performed. MeSH as well as non-MeSH terms such as "acanthosis nigricans," "classification," "pathophysiology," "diagnosis," "trea…
