Infrared photography is interesting for a use in forensic science and forensic medicine since it reveals findings that normally are almost invisible to the human eye. Originally, infrared photography has been made possible by the placement of an infrared light transmission filter screwed in front of the camera objective lens. However, this set-up is associated with many drawbacks such as the loss of the autofocus function, the need of an external infrared source, and long exposure times which make the use of a tripod necessary...

Investigations on the photochemical stability of pharmaceutical substances are mandatory in drug development and licensing as photo-induced degradation of an active pharmaceutical ingredient (API) may not only lead to decreased API concentrations but also to toxic or reactive products. Thus, the US Food and Drug Administration (FDA) and the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) issued Guidance for Industry Q1B "Photostability Testing of New Drug Substances and Products" for testing of pure but also packed drugs...

Single nanowire lasers based on bottom-up III-V materials have been shown to exhibit room-temperature near-infrared lasing, making them highly promising for use as nanoscale, silicon-integrable and coherent light sources. While lasing behavior is reproducible, small variations in growth conditions across a substrate arising from the use of bottom-up growth techniques can introduce inter-wire disorder, either through geometric or material inhomogeneity. Nanolasers critically depend on both high material quality and tight dimensional tolerances, and as such, lasing threshold is both sensitive to, and a sensitive probe of such inhomogeneity...

Industrialized drug screening campaigns usually deliver hundreds of compounds that are active on a particular pharmaceutical target. In light of high failure rates of drug candidates due to unforeseeable off-target toxicity, the early identification of the most promising compounds with high potential for target selectivity is an urgent need to improve the quality of lead compounds and lower attrition rates in the drug development process. The reliable prediction of the selectivity of active substances for a target protein is a challenging task...

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...

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...

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...

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...
