UV irradiation triggers the overproduction of matrix metalloproteinases and collagen degradation, which in turn causes increased pigmentation, dryness, and deep wrinkling of the skin. These chronic symptoms are collectively referred to as photoaging. Eucalyptus globulus is an evergreen tree that is widely used in cosmetics because of its antimicrobial activity. In this study, we investigated the protective effect of 50% ethanol extracts of Eucalyptus globulus on UV-induced photoaging in vitro and in vivo. Normal human dermal fibroblasts were treated with Eucalyptus globulus at concentrations ranging from 1 to 100 μg/mL after UVB or non-UVB irradiation...

Exposure to UV radiation to human skin up-regulates the synthesis of matrix metalloproteinase (MMP) family. Gelatinases are member of MMPs which have been suggested to play an important role in photoaging such as wrinkle formation. To inhibit gelatinase activity is regarded to be very important to keep healthy skin and to protect wrinkle formation. On the other hand, anti-photoaging agents are expected to be derived from natural resources, especially plants. Plant extracts having gelatinase-inhibitory effect that might be used as safe anti-photoaging ingredient were widely screened...

RATIONALE: Spasticity is a widespread problem in chronic stroke. To date, no study has reported the long-term (up to 1 year) outcomes of acupuncture in combination with constraint-induced movement therapy in patients with chronic stroke. This report describes the successful addition of acupuncture on spasticity and arm function in a patient with chronic stroke and arm paresis. PATIENT CONCERNS: At screening, the patient was unable to voluntarily extend her interphalangeal or metacarpophalangeal joints beyond the 10 degrees required for constraint-induced movement therapy...

Wrinkles in supported graphenes can be formed either by uniaxial compression or uniaxial tension beyond a certain critical load depending on the mode of loading. In the first case, the wrinkling direction is normal to the compression axis whereas in tension, wrinkles of the same pattern are formed parallel to the loading direction due to Poisson's (lateral) contraction. Herein we show by direct AFM observations that in simply-supported graphenes such instabilities appear as periodic wrinkles over existing stochastic undulations caused by the underlying-substrate-roughness...

Yang Wang, Xiaoping Du
A new 3D-point-cloud-based model is presented for calculating the apparent magnitude of space objects. This model does not consider topological relations of space objects, but it can accurately describe the shape of a space object and calculate its apparent magnitude. Once a 3D point cloud of a space object and its material parameters under a certain wavelength are obtained, the apparent magnitude can be solved. Through this model, the apparent magnitude of space objects with different shapes and the wrinkled surface can be calculated easily...

BACKGROUND: Collagen fibres in the dermis play an important structural role in the skin. Age-related changes to these fibres cause wrinkles and slackness of facial skin. However, it is not clear how dermal collagen fibres affect skin colour. The purpose of this study was to clarify the influence of altered collagen fibres on skin colour, using both experimental measurement of fibre density and Monte Carlo simulations in an optical model of skin. METHODS: Reflection spectra were measured from the cheeks of 12 Japanese women (22-65 years old) by spectral colorimeter...

Traffic-related air pollution is known to be associated with skin aging manifestations. We previously found that the use of fossil fuels was associated with skin aging, but no direct link between indoor air pollutants and skin aging manifestations has ever been shown. Here we directly measured the indoor PM2.5 exposure in 30 households in Taizhou, China. Based on the directly measured PM2.5 exposure and questionnaire data of indoor pollution sources, we built a regression model to predict the PM2.5 exposure in larger datasets including an initial examination group (N = 874) and a second examination group (N = 1003)...

This study describes the impact of crop genetics and processing in two pea lines (Pisum sativum L.) on starch digestion kinetics. Mutation at the rugosus (r) locus leads to wrinkled pea seeds, a reduction in starch content and a lower extent of in vitro starch digestibility. The Logarithm of Slope (LOS) kinetic model was used to analyse digestion curves obtained using porcine pancreatic α-amylase for a range of particle size fractions. Changes in starch structure induced by the r mutation led to clear differences in starch digestion kinetics for purified starches and pea flours...
