Jong-Hyeon Lee
The humidifier disinfectant disaster (HDD) was not a simple poisoning accident by biocides, but a singular disaster in history created by chemicals in household products. This disaster was a result of the failure of a system for the management of chemical and product safety. Since the management authority for chemical usage safety is different from those for chemical safety in products, many blind areas for chemical safety management in products still remain. The 'Act on the Registration and Evaluation, etc...

Objective: Religion and spirituality play an appreciable role as a problem area or as a resource for patients with mental disorders. It is therefore of interest what attitudes psychotherapists assume towards this complex range of issues in their work, but also in their personal lives. The majority of empirical studies on this subject originate from the USA, with little data being available from Europe and Germany. Our own survey among practising psychotherapists was designed to elucidate these questions. Method and Study Population: A cross-sectional study was conducted in the form of a written survey of all accessible practising psychotherapists in the area of Northern Bavaria (Franconian administrative districts; n=1 081, return rate 65%)...

Mental disorders rank first amongst all causes for disability pensions and second in the field of medical rehabilitation. Especially alarming is the significantly lower age of entry of the mentally ill disability pensioners, compared to those with other indications. Mentally ill people often look back at a long history of diseases before getting in contact with the German pension insurance. In this regard the German pension insurance, which is obligated to effectively support people in order to keep them in working life until reaching the regular retirement age, is facing a big challenge, which stands right next to further demands, due to the demographic change, the increase of chronic diseases, multimorbidity, retirement age of 67 and changes in the working environment...

BACKGROUND: Patients with schizophrenia have abnormal autonomic nervous system (ANS) activity compared with the general population. One reason for this difference is the muscarinic affinity for antipsychotic drugs; therefore, single nucleotide polymorphisms (SNPs) of the muscarinic receptor gene influence this ANS dysfunction. This study sought to determine the effect of SNPs of the cholinergic muscarinic receptor (CHRM) gene on ANS activity in patients with schizophrenia receiving antipsychotic drugs...

BACKGROUND: The primary aim of this study was to evaluate the outcomes of a series of patients with Charcot neuroarthropathy (CN) who were evaluated in a tertiary care setting. We hypothesized that those patients with CN who presented with a Charcot-related foot wound would have lower rates of successful limb salvage than patients who presented without a wound. METHODS: Two hundred forty-five patients (280 feet) were identified with diabetic CN during the time period from January 1, 2005, to June 1, 2015...

OBJECTIVE: Hypothalamic-pituitary-adrenal (HPA) measures are crucial for research into stress and stress-related disorders. Most HPA measures fluctuate depending on diurnal rhythms and state confounders. Hair cortisol concentrations (HCC) are less susceptible to such fluctuations, but less is known about trait-like confounders. Using a community sample, we tested the relationship between HCC and a range of variables including demographic variables, hair treatment, and medication, as well as psychosocial variables, namely childhood trauma, critical life events, and depressive symptoms...

Meso-2,3-dimercaptosuccinic acid (DMSA) is used in nuclear medicine as ligand for preparation of diagnostic and therapy radiopharmaceuticals. DMSA has been the subject of numerous investigations during the past three decades and new and significant information of the chemistry and pharmacology of DMSA complexes have emerged. In comparison to other ligands, the structure of some DMSA complexes is unclear up today. The structures and applications of DMSA complexes are strictly dependent on the chemical conditions of their preparation, especially pH and components ratio...

The protein kinases (PKs), belonging to serine/threonine kinase (STKs), are important drug targets for a wide spectrum of diseases in human. Among protein kinases, the Casein Kinases (CKs) are vastly expanded in various organisms, where, the malarial parasite Plasmodium falciparum possesses a single member i.e., PfCKI, which can phosphorylate various proteins in parasite extracts in vitro condition. But, the structure-function relationship of PfCKI and dynamics of ATP binding is yet to be understood. Henceforth, an attempt was made to study the dynamics, stability, and ATP binding mechanisms of PfCKI through computational modelling, docking, molecular dynamics (MD) simulations, and MM/PBSA binding free energy estimation...

Environmental concern about automotive shredder residue (ASR) has increased in recent years due to its harmful content of heavy metals. Although several approaches of ASR management have been suggested, these approaches remain commercially unproven. This study presents an alternative approach for ASR management where advanced materials can be generated as a by-product. In this approach, titanium nitride (TiN) has been thermally synthesized by nitriding pressed mixture of automotive shredder residue (ASR) and titanium oxide (TiO2)...

BACKGROUND: Many disease entities, including coronary artery disease (CAD), demonstrate abnormalities in the activity of cholinesterases. As CAD is characterized by an increase in cholesterol level, patients with this disease are treated with lipid-lowering drugs. The present study attempts to determine how statin or combined statin and ezetimibe therapy influences cholinesterase activity. METHODS: Plasma and erythrocytes were isolated from the peripheral blood of CAD patients (n=61) and healthy subjects (n=63)...

Shogo Koshiya, Koji Kimoto
This paper describes the effective solid angle improvement achieved using a large-area silicon drift detector together with a virtual-pivot double-tilt specimen holder. The virtual-pivot mechanism enables various designs of specimen-retaining and can reduce the shadowing effect. Energy-dispersive X-ray spectra were measured and converted into effective solid angles using different types of specimen holders and specimens. The investigated shadowing-free mechanical system yielded effective solid angles approaching the nominal solid angle of 0...

Nitrogen-doped graphene (N/GR) has been considered as active metal-free electrocatalysts for oxygen reduction reaction (ORR). However, the nitrogen (N) doping efficiency is very low and only few N atoms are doped into the framework of GR. To boost the N doping efficiency, in this work, a confined pyrolysis method with high N doping efficiency is used for the preparation of cobalt nanoparticles/nitrogen-doped GR (Co/N/GR). Under the protection of SiO2, the inorganic ligand NH3 in cobalt amine complex ([Co(NH3)6](3+)) is trapped in the confined space and then can be effectively doped into the framework of GR without the introduction of any carbon residues...

Advanced techniques for overcoming problems encountered during in situ electron holography experiments in which a voltage is applied to an ionic conductor are reported. The three major problems encountered were 1) electric-field leakage from the specimen and its effect on phase images, 2) high electron conductivity of damage layers formed by the focused ion beam method, and 3) chemical reaction of the specimen with air. The first problem was overcome by comparing experimental phase distributions with simulated images in which three-dimensional leakage fields were taken into account, the second by removing the damage layers using a low-energy narrow Ar ion beam, and the third by developing an air-tight biasing specimen holder...

In a new study, DNA from a 5,310-year-old corn cob found in the Tehuacán Valley in Mexico was sequenced and compared to modern maize and its wild progenitor grasses. The sample was found to be an intermediate between modern maize and its wild relatives, suggesting a gradual, protracted domestication process.

The Triassic, lasting from 252 to 201 million years (Myr) ago, was crucial in the origin of modern ecosystems. It is the seventh of the 11 geological systems or periods into which the Phanerozoic, the fossiliferous last 540 million years, of Earth history is divided. It might seem strange to select just one of these divisions of time as somehow more significant than the others. However, this was the span of time during which all of the key modern vertebrate groups originated - the neoselachian sharks, neopterygian bony fishes, lissamphibians, turtles, lepidosaurs, crocodilomorphs, and mammals...

Tissue morphogenesis requires force-generating mechanisms to organize cells into complex structures. Although many such mechanisms have been characterized, we know little about how forces are integrated across developing tissues. We provide evidence that integrin-mediated cell-extracellular matrix (ECM) adhesion modulates the transmission of apically generated tension during dorsal closure (DC) in Drosophila. Integrin-containing adhesive structures resembling focal adhesions were identified on the basal surface of the amnioserosa (AS), an extraembryonic epithelium essential for DC...
