Epithelial-mesenchymal transition (EMT) has been suggested to have a driving role in the acquisition of a metastatic potential by melanoma cells. Important hallmarks of EMT include both E-cadherin downregulation and increased expression of N-cadherin. This switch in distinct classes of adhesion molecules leads melanoma cells to lose contact with adjacent keratinocytes and interact instead with stromal fibroblasts and endothelial cells, thus promoting dermal and vascular melanoma invasion. Consequently, tumor cells migrate to distant host tissues and establish metastases...

The low activity allele of the maternal polymorphism, 5HTTLPR, in the serotonin transporter, SLC6A4, coupled with prenatal stress is reported to increase the risk for children to develop autism spectrum disorder (ASD). Similarly, maternal Slc6a4 knock-out and prenatal stress in rodents results in offspring demonstrating ASD-like characteristics. The present study uses an integrative genomics approach to explore mechanistic changes in early brain development in mouse embryos exposed to this maternal gene-environment phenomenon...

The ability to predict reward promotes animal survival. Both dopamine neurons in the ventral tegmental area (VTA) and serotonin neurons in the dorsal raphe nucleus (DRN) participate in reward processing. Although the learning effects on dopamine neurons have been extensively characterized, it remains largely unknown how the response of serotonin neurons evolves during learning. Moreover, while stress is known to strongly influence reward-related behavior, we know very little about how stress modulates neuronal reward responses...

The recent surge in medical disputes requires that more attention be paid to the voices of laypeople. This article explores the argumentative nature of the public discourse of the reported "malpractice mobs" that strive to convince members of the public (in the place of health or legal experts) that they have been victims of medical errors and injustice. This case-based qualitative empirical study uses a pragma-dialectical approach to suggest a prototypical pattern of such public appeals that contains a basic argumentative pattern and various types of extensions...

Recently, a collective variable "proton indicator" was purposed for tracking an excess proton solvated in bulk water in molecular dynamics simulations. In this work, we demonstrate the feasibility of utilizing the position of this proton indicator as a reaction coordinate to model an excess proton migrating through a hydrophobic carbon nanotube in combined quantum-mechanics/molecular-mechanics simulations. Our results indicate that applying a harmonic restraint to the proton indicator in the bulk solvent near the nanotube pore entrance leads to the recruitment of water molecules into the pore...

Manali Ghosh, Chad M Rienstra
Rotational echo double resonance (REDOR) is a highly successful method for heteronuclear distance determination in biological solid-state NMR, and 1H detection methods have emerged in recent years as a powerful approach to improving sensitivity and resolution for small sample quantities by utilizing fast magic-angle spinning (>30 kHz) and deuteration strategies. In theory, involving 1H as one of the spins for measuring REDOR effects can greatly increase the distance measurement range, but few experiments of this type have been reported...

REVIEW

Flaviviruses, such as dengue, Japanese encephalitis, West Nile, yellow fever, and Zika viruses, are serious human pathogens that cause significant morbidity and mortality globally each year. Flaviviruses are single-stranded, positive-sense RNA viruses, and encode two multidomain proteins, NS3 and NS5, that possess all enzymatic activities required for genome replication and capping. NS3 and NS5 interact within virus-induced replication compartments to form the RNA genome replicase complex. Although the individual enzymatic activities of both proteins have been extensively studied and are well characterized, there are still gaps in our understanding of how they interact to efficiently coordinate their respective activities during positive-strand RNA synthesis and capping...

Michael J Diamond
In addressing the central challenges of developing and maintaining the analyst's psychoanalytic mindedness, this paper focuses on two particularly challenging core components of clinical effectiveness not so easily developed despite the rigors of the tripartite training model. The first is the analyst's receptivity to unconscious communication, which entails the analyst's curiosity, acceptance of human nature, doubt, restraint, narcissistic balance, and integrity. A brief clinical vignette illustrates this...

Adrenergic signaling is known to promote tumor growth and metastasis, but the effects on tumor stroma are not well understood. An unbiased bioinformatics approach analyzing tumor samples from patients with known biobehavioral profiles identified a prominent stromal signature associated with cancer-associated fibroblasts (CAFs) in those with a high biobehavioral risk profile (high Center for Epidemiologic Studies Depression Scale [CES-D] score and low social support). In several models of epithelial ovarian cancer, daily restraint stress resulted in significantly increased CAF activation and was abrogated by a nonspecific β-blocker...

OBJECTIVE: Post-intensive care syndrome (PICS), which encompasses profound psychological morbidity, affects many survivors of critical illness. We hypothesize that acute psychological stress during the intensive care unit (ICU) confinement likely contributes to PICS. In order to develop strategies that mitigate PICS associated psychological morbidity, it is paramount to first characterize acute ICU psychological stress and begin to understand its causative and protective factors. METHODS: A structured interview study was administered to adult critical illness survivors who received ≥48h of mechanical ventilation in medical and surgical ICUs of a tertiary care center, and their families...

REVIEW
Allison Tadros, Christopher Kiefer
Violence against health care workers is an unfortunately common event. Because of several inherent factors, emergency departments are particularly vulnerable. Once an incident occurs, it often goes unreported and leads to both physical and mental trauma. Health care workers should learn to recognize the cues that patients are escalating toward violence and be familiar with various options for sedating agitated patients. If sedation is not successful, physical restraint may become necessary. There are measures that can be taken that may help minimize the likelihood of violence toward health care workers...

The G protein-coupled receptor 55 (GPR55) is a novel cannabinoid receptor, whose exact role in anxiety remains unknown. The present study was conducted to explore the possible mechanisms by which GPR55 regulates anxiety and to evaluate the effectiveness of O-1602 in the treatment of anxiety-like symptoms. Mice were exposed to two types of acute stressors: restraint and forced swimming. Anxiety behavior was evaluated using the elevated plus maze and the open field test. We found that O-1602 alleviated anxiety-like behavior in acutely stressed mice...
