This manuscript elaborates on the establishment of a chemotaxonomic classification strategy for closely-related Citrus fruits in Traditional Chinese Medicines (TCMs). UPLC-Q-TOF-MS-based metabolomics was applied to depict the variable chemotaxonomic markers and elucidate the metabolic mechanism of Citrus TCMs from different species and at different ripening stages. Metabolomics can capture a comprehensive analysis of small molecule metabolites and can provide a powerful approach to establish metabolic profiling, creating a bridge between genotype and phenotype...

The work describes features of the compressed sensing (CS) approach utilized for development of a wearable system for wrist vein recognition with single-pixel detection; we consider this system useful for biometrics authentication purposes. The CS approach implies use of a spatial light modulation (SLM) which, in our case, can be performed differently - with a liquid crystal display or diffusely scattering medium. We show that compressed sensing combined with above mentioned means of spatial light modulation allows us to avoid using an optical system - a limiting factor for wearable devices...

Optical characteristics of luminescent materials, such as emission profile and lifetime, play an important role in their applications in optical data storage, document security, diagnostics, and therapeutics. Lanthanide-doped upconversion nanoparticles are particularly suitable for such applications due to their inherent optical properties, including large anti-Stokes shift, distinguishable spectroscopic fingerprint, and long luminescence lifetime. However, conventional upconversion nanoparticles have a limited capacity for information storage or complexity to prevent counterfeiting...

In New York City, a man and his therapist talk about shame as a psychological, bodily, gendered, and social experience that pervades even the consulting room. They describe and analyze trauma and guilt against the background of a common Mediterranean culture they experienced while growing up, albeit from different gendered and class positions. The patient's modest presenting complaint of blushing opens into an exploration that results in an unexpectedly profound transformation. Ultimately, therapy helps him acknowledge and process his traumatic experience of circumcision and other traumas...

Screening procedures using high resolution (HR)-mass spectrometry (MS) are getting more and more important e.g. for drug testing or adherence monitoring. Approaches usually include time-consuming sample preparation and compound separation by liquid chromatography (LC). The paper spray ionization (PSI) technique coupled to MS might overcome these steps by direct analysis of complex mixtures without extraction and separation. In recent years, this technology proved its potential for quantification and/or qualitative screening in biofluids...

BACKGROUND: Both Panax ginseng Meyer and Panax quinquefolius are obligate shade-loving plants whose natural habitats are broadleaved forests of Eastern Asia and North America. Panax species are easily damaged by photoinhibition when they are exposed to high temperatures or insufficient shade. In this study, a cytohistological study of the leaf structures of two of the most well-known Panax species was performed to better understand the physiological processes that limit photosynthesis...

Hypoxia-like incidents in-flight have increased over the past decade causing severe safety concerns across the aviation community. As a result, the need to monitor flight crews in real-time for the onset of hypoxic conditions is paramount for continued aeronautical safety. Here, hypoxic events were simulated in the laboratory via a reduced oxygen-breathing device to determine the effect of recovery gas oxygen concentration (21% and 100%) on exhaled breath volatile organic compound (VOC) composition. Data from samples collected both serially (throughout the exposure), prior to, and following exposures yielded 326 statistically significant features, 203 of which were unique...

Direct comparison of authentic ciliatamide A with four synthetic isomers (1-4) by means of NMR and chiral-phase HPLC revealed that ciliatamide A possesses the 12R (d-N-MePhe residue) and 22S (l-Lys residue) configurations, which were not identical with either our previous assignment or those proposed by others through total synthesis. The absolute configuration of the methionine sulfoxide residue in ciliatamide D was also revised to be d.

The survivor of a decade of childhood sexual trauma and violence, perpetrated by a monstrous father, produced a series of dreams in the final year of a ten-year analysis. They illuminated the 'death drive' beneath a lifelong preoccupation with dying and fantasies of submission to death, perpetuated by the promise of hoped-for freedom from pain and release from a life of suffering. The initial dream involved the collapse of a team of white horses drawing him in a pillory cart to his own hanging for a crime he did not commit...

This paper looks at systems of gender within the context of analysis. It explores the unique challenges of individuation faced by transsexual, transgender, gender queer, gender non-conforming, cross-dressing and intersex patients. To receive patients generously we need to learn how a binary culture produces profound and chronic trauma. These patients wrestle with being who they are whilst simultaneously receiving negative projections and feeling invisible. While often presenting with the struggles of gender conforming individuals, understanding the specifically gendered aspect of their identity is imperative...

Hoogsteen base pairs are seen in DNA crystal structures, but only rarely. This study tests whether Hoogsteens or other syn purines are either under-modeled or over-modeled, which are known problems for rare conformations. Candidate purines needing a syn/anti 180° flip were identified by diagnostic patterns of difference electron-density peaks. Manual inspection narrowed 105 flip candidates to 20 convincing cases, all at ≤2.7 Å resolution. Rebuilding and refinement confirmed that 14 of these were authentic purine flips...
