The structures of solids can locally differ from the macroscopic picture obtained by structural averaging techniques. This difference significantly influences the performance of any functional material. Measurements of these local structures are challenging. Thus, the description of defects is often disregarded. However, in order to understand the functionality, such irregularities have to be investigated. Here, we present a high resolution scanning transmission electron microscopic (STEM) study revealing local structural irregularities in open structured oxides using catalytically active orthorhombic (Mo,V,Te,Nb)Ox as a complex example. Detailed analysis of annular dark field- and annular bright field-STEM images reveal site specific local structural displacements of individual framework and channel sites in the picometer range. These experimental observables can be considered as an important structural addendum for theoretical modelling and should be implemented into the existing data in order to quantify site specific potential energies and stresses. This information can further be used to describe the impact of the structure on the catalytic performance in greater detail.The aim of this study was to determine the effects of soybean protein hydrolysates against intracellular antioxidant activity. Soybean peptides (1000 to 2000 Da range) were extracted by soybean proteolysis and ultrafiltration and sequenced with a Nano-LC-ESI-MS/MS. In this study we found that soybean peptides inhibited the production of reactive oxygen species (ROS) induced by hydrogen peroxide (H2O2), malondialdehyde (MDA) and oxidized glutathione (GSSG) in HepG2 cells. Moreover, they also prevented the reduction of reduced glutathione (GSH) and up-regulated cellular resistance oxidase activity. In addition, soybean peptide treatment stimulated the mRNA and protein expression levels of antioxidant enzymes and nuclear factor erythroid-2-related factor 2 (Nrf2). Activated Nrf2 up-regulated antioxidant enzyme activities (superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px)) and inhibited ROS and MDA production. It was concluded that soybean peptides effectively activated the Nrf2/antioxidant response element (ARE) mediated activity.A Quantum Cascade Laser (QCL) was invented in the late 90s as a promising mid-infrared light source and it has contributed to the fields of industry, military, medicine, and biology. The room temperature operation, watt-level output power, compact size, and wide tuning capability of this laser advanced the field of noninvasive blood glucose detection with the use of transmission, absorption, and photoacoustic spectroscopy. This review provides a complete overview of the recent progress and technical details of these spectroscopy techniques, using QCL as an infrared light source for detecting blood glucose concentrations in diabetic patients.Using density functional theory (DFT), we studied the formation of Stone-Wales defects in pyrene, as a prototype PAH molecule. In addition, we studied the reactivity of the defective and pristine pyrenes toward hydrogenation, a process that can occur in some regions of the interstellar medium. We found that the formation of the defect requires overcoming energies of the order of 8.4 eV, but the defective structure is stable due to the high reverse reaction barrier (approx. 6 eV). We also found that the presence of the defect decreases the sticking barrier for the first hydrogenation and promotes more stable singly and doubly hydrogenated intermediates with respect to that of the pristine pyrene. Finally, our results show that both Stone-Wales pyrene and pristine pyrenes can lead to the formation of H2 through an extraction mechanism involving H atoms attached on distal carbon atoms with energy barriers below 2 eV.Fiona Martin is a psychiatry trainee who spent 6 months volunteering in a mental health service in Uganda between her core and higher psychiatry training. In this article, she reflects upon this experience, including the challenges and rewards, and in particular the benefits to training of such an experience. © The Author 2019.Sri Lanka ranks highest in the region for human development. Despite producing the first female head of state in the world, the country has failed to achieve substantial gains in the gender inequality indices in the past decade. In recent years, the proportion of females in secondary education has equalled that of males, and young women have become the majority among the university entrants. These educated young women are likely to face psychosocial distress in a patriarchal society where they would be expected to fulfil traditional gender roles. This article describes gender disparities that could affect the mental well-being of young Sri Lankan women and the need for awareness among mental health professionals in the country. © The Authors 2018.The history of psychiatry and homosexuality illuminates how stigma develops in the professions, how it is linked to cultural values and religious attitudes and how it affects patients. Homosexuality was medicalised as a disorder in the late 19th century and this led to treatments to change it. Same-gender contacts between men were decriminalised in many countries in the 1960s and 1970s, but - as recently as the 1980s - 30% of doctors in the USA did not think that gay students should be admitted to medical school and 40% would not allow gay doctors to specialise in paediatrics or psychiatry. https://www.selleckchem.com/products/edralbrutinib.html Lesbians and gay men were effectively debarred from training in the main psychoanalytical schools in the USA and the UK. Although mainstream psychological treatments to make gay and bisexual people heterosexual fell into disrepute in the 1980s, so-called conversion or reparative treatments took their place and are still practised today. Transgender people have been the target of similar disapproval and attitudes towards them have been even slower to change than those towards lesbians and gay men. This stigma had consequences on the health, well-being and social inclusion of those who were lesbian, gay, bisexual and transgender (LGBT). This history suggests we need to examine where psychiatry and psychology are making similar mistakes today. © The Author 2019.
