Mina Arefian, Masoud Mirzaei, Hossein Eshtiagh-Hosseini, Antonio Frontera
One of the most attractive areas in inorganic chemistry is the synthesis of polyoxometalates (POMs) exhibiting new properties and applications. Since the impact of POMs in biochemistry and related fields of research has increased in the last few years, there has been a special interest in this topic. Significant progress in biological applications has been made where the interaction of POMs with amino acids, peptides and proteins is relevant. Versatile POMs play a series of different roles in the interaction with these biomolecules as described in this review...

Jim R Sliwinski, Gary R Elkins
The mechanism of action responsible for hypnotherapy's effect in reducing hot flashes is not yet known. The purpose of this study was to examine the role of response expectancies as a potential mediator. Hypnotizability was also tested as an effect moderator. Data were collected from a sample of 172 postmenopausal women, who had been randomized to receive either a 5-week hypnosis intervention or structured attention counseling. Measures of response expectancies were analyzed to determine if the relationship between group assignment and hot flashes frequency was mediated by expectancies for treatment efficacy...

This paper examines the organisational dynamics that arise in health promotion aimed at reducing health inequalities. The paper draws on ethnographic fieldwork among public health officers in Danish municipalities and qualitative interviews from an evaluation of health promotion programmes targeting homeless and other marginalised citizens. Analytically, we focus on 'boundary work', i.e. the ways in which social and symbolic boundaries are established, maintained, transgressed and negotiated, both at the administrative level and among frontline professionals...

Moral psychology research has highlighted several factors critical for evaluating the morality of another's choice, including the detection of norm-violating outcomes, the extent to which an agent caused an outcome, and the extent to which the agent intended good or bad consequences, as inferred from observing their decisions. However, person-centered accounts of moral judgment suggest that a motivation to infer the moral character of others can itself impact on an evaluation of their choices. Building on this person-centered account, we examine whether inferences about agents' moral character shape the sensitivity of moral judgments to the consequences of agents' choices, and agents' role in the causation of those consequences...

The recent development of gene editing platforms enables making precise changes in the genome of eukaryotic cells. Programmable nucleases, such as meganucleases, zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and clustered regularly interspaced short palindromic repeat (CRISPR)-associated nucleases, have revolutionized the way research is conducted as they facilitate the rapid production of mutant or knock-out cellular and animal models. These same genetic tools can potentially be applied to cure or alleviate a variety of diseases, including genetic diseases that lack an efficient therapy...

Switzerland with its decentralized, liberal health system and its tradition of direct democracy may be an ideal place for shared decision making (SDM) to take root organically, rather than using top-down regulations seen in other countries. There are now multiple directives and programmes in place to encourage SDM, with the creation of several decision aids and specific training programs in the five Swiss medical schools. There has been an emphasis on preventive care, with the integration of patient preference into an organized colorectal cancer screening program, clear recommendations for prostate cancer screening, and inroads into the primary prevention of cardiovascular disease...

Alzheimer's disease (AD) is a neurodegenerative disorder of the elderly. As the prevalence of AD rises in the 21st century, there is an urgent need for the development of effective pharmacotherapies. Currently, drug treatments target the symptoms of the disease and do not modify or halt the disease progress. Thus, natural compounds have been investigated for their ability to treat AD. This review examines the efficacy of curcumin, a polyphenol derived from turmeric herb, to treat AD. We summarize the in vivo and in vitro research describing the mechanisms of action in which curcumin modifies AD pathology: curcumin inhibits the formation and promotes the disaggregation of amyloid-β plaques, attenuates the hyperphosphorylation of tau and enhances its clearance, binds copper, lowers cholesterol, modifies microglial activity, inhibits acetylcholinesterase, mediates the insulin signaling pathway, and is an antioxidant...

The 2014 Surgeon General's Report on smoking and health concluded that changing cigarette designs have caused an increase in lung adenocarcinomas, implicating cigarette filter ventilation that lowers smoking machine tar yields. The Food and Drug Administration (FDA) now has the authority to regulate cigarette design if doing so would improve public health. To support a potential regulatory action, two weight-of-evidence reviews were applied for causally relating filter ventilation to lung adenocarcinoma. Published scientific literature (3284 citations) and internal tobacco company documents contributed to causation analysis evidence blocks and the identification of research gaps...

Psychological flexibility, a complex concept encompassing both acceptance and action related factors, has been identified as a target for intervention for diabetes management. Research suggests acceptance, self-management, and stress, all factors that influence psychological flexibility, have an impact on adaptation to type 1 diabetes (T1D) by youth independently. However, yet to be explored is individually varying patterns of these variables and how they may relate to diabetes adaptation outcomes. The present study aimed to establish individual variations of patterns of these factors to derive profiles of psychological flexibility, and examine their relations to the adaptation outcomes of glycemic control and health-related quality of life...

Toner formulations used by laser printers (LP) and photocopiers (PC), collectively called "toner-based printing equipment" (TPE), are nano-enabled products (NEP) because they contain several engineered nanomaterials (ENM) that improve toner performance. It has been shown that during consumer use (printing), these ENM are released in the air, together with other semi-volatile organic nanoparticles, and newly formed gaseous co-pollutants such as volatile organic compounds (VOC). The aim of this review is to detail and analyze physico-chemical and morphological (PCM), as well as the toxicological properties of particulate matter (PM) emissions from TPE...

MicroRNAs are essential regulators of various cellular processes such as cell growth, differentiation, apoptosis, and the immune response, acting as factors for translational repression and/or degradation of target messenger RNA. Currently, microRNAs are considered as promising biomarkers and therapeutic targets for different pathological conditions. Skin may serve as a convenient model for microRNA modulation studies due to the comparatively easy access to targets cells. Cutaneous diseases are characterized by multiple intercellular communication pathways, triggered by diverse stimuli and mediated by heterogenous regulators, including microRNAs...

Tao Cui, Hai Hou, Yao Sun, Huaixing Cang, Xiangxi Wang
Small molecule drugs obtained from synthetic compounds or natural products show their therapeutic effects by specifically binding to one or a few target proteins and modulating their functions. In contrast, undesirable drug-protein interactions may provoke harmful side effects. Furthermore, drug-protein interactions also play roles in drug activation, transport, metabolism and regulation of drug resistance. Therefore, systematically identifying binding proteins of a drug molecule is critical for understanding the mechanism of action of the drug at molecular level...

Routine outcome monitoring (ROM) and clinical feedback (CF) systems have become important tools for psychological therapies, but there are challenges for their successful implementation. OBJECTIVE: To overcome these challenges, a greater understanding is needed about how patients experience the use of ROM/CF. METHOD: We conducted a systematic literature search of qualitative studies on patient experiences with the use of ROM/CF in mental health services. RESULTS: The findings from 16 studies were synthesized, resulting in four meta-themes: (1) Suspicion towards service providers, (2) Flexibility and support to capture complexity, (3) Empowering patients, and (4) Developing collaborative practice...

Academic psychologists' backgrounds may prepare them for many aspects of academic administration such as: understanding and working with people; prioritizing others' needs and institutional needs; and managing projects and budgets, e.g., for research grants or training programs. Contemporary academic health centers also may provide opportunities for psychologists to serve in academic health administration. This article encourages psychologists to consider preparing for and seeking administrative and higher-level leadership roles...

Ward rules in psychiatric care aim to promote safety for both patients and staff. Simultaneously, ward rules are associated with increased patient violence, leading to neither a safe work environment nor a safe caring environment. Although ward rules are routinely used, few studies have explicitly accounted for their impact. To describe the process of a team development project considering ward rule issues, and to develop a working model to empower staff in their daily in-patient psychiatric nursing practices...

While numerous studies have examined the relationships between facial actions and emotions, they have yet to account for the ways that specific spontaneous facial expressions map onto emotional experiences induced without expressive intent. Moreover, previous studies emphasized that a fine-grained investigation of facial components could establish the coherence of facial actions with actual internal states. Therefore, this study aimed to accumulate evidence for the correspondence between spontaneous facial components and emotional experiences...

Accurate and reliable measurements of exposure to tobacco products are essential for identifying and confirming patterns of tobacco product use and for assessing their potential biological effects in both human populations and experimental systems. Due to the introduction of new tobacco-derived products and the development of novel ways to modify and use conventional tobacco products, precise and specific assessments of exposure to tobacco are now more important than ever. Biomarkers that were developed and validated to measure exposure to cigarettes are being evaluated to assess their utility for measuring exposure to these new products...
