N-methylol compounds, such as dimethyloldihydroxyethyleneurea (DMDHEU), are the most commonly used durable press finishing agents for cotton fabrics. Polyfunctional carboxylic acids are becoming important as non-formaldehyde replacements for these N-methylol reactants. The use of both chemistries has been shown to cause an irreversible reduction in the physical properties of finished fabric, be...

Two simple geometric rules predict the wrinkle patterns of curved surfaces that are flattened.

Finding valid indicators of emotional states is one of the biggest challenges in animal welfare science. Here, we investigated in horses whether variation in the expression of eye wrinkles caused by contraction of the inner eyebrow raiser reflects emotional valence. By confronting horses with positive and negative conditions, we aimed to induce positive and negative emotional states, hypothesis...

BACKGROUND AND OBJECTIVES In this preliminary prospective study, we evaluated the efficacy and safety of nonablative wrinkle treatment using combined radiofrequency (RF) and optical energy (Polaris). The dual energy technology of Polaris, called ELOS, which stands for electro-optical synergy, uses synchronous pulses of bipolar RF current and pulsed visible light (diode laser) delivered in the s...

BACKGROUND Fractional CO2 -laser resurfacing is increasingly used for treating rhytides and photoaged skin because of its favorable benefit-risk ratio. A key outcome measure and treatment goal in aesthetic laser therapy is patient satisfaction. However, few data are available on patient-reported outcomes after fractional ablative skin-resurfacing. OBJECTIVES To compare patient expectations be...

OBJECTIVE The aim of this study was to evaluate the effects of water-soluble egg membrane (WSEM) on wrinkle reduction in a clinical pilot study and to elucidate specific mechanisms of action using primary human immune and dermal cell-based bioassays. METHODS To evaluate the effects of topical application of WSEM (8%) on human skin, an open-label 8-week study was performed involving 20 healthy...

Skin is in direct contact with the environment and therefore undergoes aging as a consequence of environmentally induce damage. Wrinkle formation is a striking feature of intrinsic and photo-induced skin aging, which are both associated with oxidative stress and inflammatory response. The present study was undertaken to identify the mechanisms responsible for the anti-wrinkle effects of MLB, an...
