In women with lightly pigmented skin in particular, facial skin color homogeneity decreases with age, primarily due to chronic exposure to solar ultraviolet radiation (UVR), leading to a decrease in perceived health and attractiveness. Perception of female skin may be influenced by continuous exposure to, and thus familiarity with, age-related changes in visible skin condition in a given society. Men and women of two traditional societies, the Maasai (Tanzania) and the Tsimane' (Bolivia), unfamiliar with lighter colored skin, judged images of British women's facial skin for age, health, and attractiveness...

Boneless loins ( = 286) were selected from a population of pigs of a common genetic line and management strategy to be used in an experiment to determine the effects of instrumental color and extractable lipid content on sensory traits of boneless pork chops cooked to an end point internal temperature of 63°C. Loins were cut into 2.54-cm-thick chops and aged until 14 d postmortem. Chop L* values ranged from 57.60 (light) to 43.11 (dark) and extractable lipid ranged from 0.80 to 5.52%. Using these values, chops were assigned to 5 color and 6 marbling categories using National Pork Producers Council (NPPC) standards, resulting in a 5 × 6 factorial arrangement of treatments...

The increasing demand for light emitting diodes (LEDs) is driven by a number of application categories, including display backlighting, communications, signage, and general illumination. Nowadays, they have also become attractive candidates as new photometric standards. In recent years, LEDs have started to be applied as wavelength-selective photo-detectors as well. Nevertheless, manufacturers' datasheets are limited about LEDs used as sources in terms of degradation with operating time (aging) or shifting of the emission spectrum as a function of the forward current...

We report a light, flexible, and low-power poly(ionic liquid)/alumina composite CO2 sensor. We monitor the direct-current resistance changes as a function of CO2 concentration and relative humidity and demonstrate fast and reversible sensing kinetics. Moreover, on the basis of the alternating-current impedance measurements we propose a sensing mechanism related to proton conduction and gas diffusion. The findings presented herein will promote the development of organic/inorganic composite CO2 gas sensors. In the future, such sensors will be useful for numerous practical applications ranging from indoor air quality control to the monitoring of manufacturing processes...

Due to the increasing life expectancy and a higher incidence in the elderly, the number of elderly patients with idiopathic Parkinson's disease will increase in the coming years. Since the burden of comorbidities is higher and medication side effects are more likely in the elderly, particularly in the light of frequently occurring polypharmacy, increased awareness and therapeutic knowledge is necessary. Besides the therapy of motor symptoms, non-motor symptoms, e. g. neuropsychiatric and autonomic disorders, also need to be addressed as they can also greatly impair the quality of life...

Aerotaxis, the directed migration along oxygen gradients, allows many microorganisms to locate favorable oxygen concentrations. Despite oxygen's fundamental role for life, even key aspects of aerotaxis remain poorly understood. In Bacillus subtilis, for example, there is conflicting evidence of whether migration occurs to the maximal oxygen concentration available or to an optimal intermediate one, and how aerotaxis can be maintained over a broad range of conditions. Using precisely controlled oxygen gradients in a microfluidic device, spanning the full spectrum of conditions from quasi-anoxic to oxic (60 n mol/l-1 m mol/l), we resolved B...

Yuanbo Deng, Daping Chu
Coherence properties of different light sources and how they affect the image quality of holographic display are investigated. Temporal coherence is related to the intrinsic spectrum bandwidth of the light source, while spatial coherence can be affected by the size of the light source and propagation distance in use. These two coherence properties are measured for various light sources of diode-pumped solid-state (DPSS) laser, laser diode (LD), light emitting diode (LED), super luminescent light emitting diode (sLED) and micro light emitting diode (mLED) in different settings, together with the quality of the holographic reconstructed images...

BACKGROUND: Objectively measured physical activity (PA) intensity has traditionally been categorised as light, moderate and vigorous using laboratory calibrated cut-points. The relative contribution of time spent across a spectrum of accelerometer-determined intensities on health outcomes is less clear. PURPOSE: To assess the relationship between objectively measured PA intensity on a continuous scale and markers of insulin sensitivity. METHODS: Participants at high risk of type 2 diabetes were recruited from primary care (Leicestershire, UK)...

In light of the ongoing debate about health care policy in the United States, including efforts to repeal and replace the Affordable Care Act, it will be critically important for the academic community to engage in the dialogue. Developing a viable approach to health care reform requires an understanding of the interaction and interdependence between choice, cost, and coverage in a competitive and functional market-based system. Some institutions have implemented models that indicate the feasibility of providing high-quality, efficient patient care while working within fixed budgets...

Plants generate protective molecules in response to UV light. In laboratory experiments, 48 h UV-B irradiation of peach fruit and leaves reduced the flavor-related monoterpene linalool by 60 %. No isoprene was detected but other terpenoids increased significantly, including a 3-fold accumulation of the sesquiterpene (E,E)-α-farnesene, which was also increased by jasmonic acid treatment. RNA-sequencing revealed altered transcript levels for two terpene synthases: PpTPS1, a TPS-g subfamily member, decreased by 86 % and PpTPS2, a TPS-b subfamily member, increased 80-fold...

BACKGROUND: Even relatively low serum bilirubin concentrations can cause neurodevelopmental impairment in extremely low birth weight (EBWL) infants, while sequelae from hyperbilirubinemia in late preterm and term infants are rare and occur only at very high serum bilirubin lev-els. Phototherapy is the current treatment of choice. OBJECTIVE: To present an update on the most important issues involved in phototherapy for jaundiced infants. RESULTS: Light absorption by bilirubin in the skin transforms the native Z,Z-bilirubin to conformational photoisomers Z,E-bilirubin and E,Z-bilirubin and structural photoisomers E,Z-lumirubin and E,E-lumirubin...

The oxygen evolution reaction (OER) at the surface of semiconductor photoanodes is critical for photoelectrochemical water splitting. This reaction involves photo-generated holes that oxidize water via charge transfer at the photoanode/electrolyte interface. However, a certain fraction of the holes that reach the surface recombine with electrons from the conduction band, giving rise to the surface recombination loss. The charge transfer efficiency, ηt, defined as the ratio between the flux of holes that contribute to the water oxidation reaction and the total flux of holes that reach the surface, is an important parameter that helps to distinguish between bulk and surface recombination losses...

This study investigated the effect of NaCl (2 and 4% (w/v)) and vacuum impregnation (VI) (150, 200, 250, and 300 Pa) on the quality parameters (water uptake, elongation ratio, visual color, and texture), tocols, γ-oryzanol and phenolic compounds of parboiled rice. Parboiling with NaCl and VI resulted in increased lightness and higher concentrations of bioactive compounds than rice parboiled by the traditional method. The highest concentration of tocopherols, γ-oryzanol, and phenolic acids (syringic, and ferulic acids) were obtained from parboiled rice with NaCl concentration at 2% (w/v) and VI at 250 and 300 Pa...
