Carbon dioxide is an important environmental cue for many insects, regulating many behaviors including some that have direct human impacts. To further improve our understanding of how this system varies among closely related insect species, we examined both the behavioral response to CO2 as well as the transcriptional profile of key developmental regulators of CO2 sensory neurons in the olfactory system across the Drosophila genus. We found that CO2 generally evokes repulsive behavior across most of the Drosophilids we examined, but this behavior has been lost or reduced in several lineages...

Dreams have produced art, music, novels, films, mathematical proofs, designs for architecture, telescopes, and computers. Dreaming is essentially our brain thinking in another neurophysiologic state-and therefore it is likely to solve some problems on which our waking minds have become stuck. This neurophysiologic state is characterized by high activity in brain areas associated with imagery, so problems requiring vivid visualization are also more likely to get help from dreaming. This article reviews great historical dreams and modern laboratory research to suggest how dreams can aid creativity and problem-solving...

INTRODUCTION: REM sleep deprivation is associated with impairment in learning and memory, and nicotine treatment has been shown to attenuate this effect. Recent studies have demonstrated the importance of DREAM protein in learning and memory processes. This study investigates the association of DREAM protein in REM sleep-deprived rats hippocampus upon nicotine treatment. METHODS: Male Sprague Dawley rats were subjected to normal condition, REM sleep deprivation and control wide platform condition for 72 hr...

Assessment of dermal exposure to chemicals in the work environment is problematic, mainly as a result of the lack of measurement data on occupational exposure to chemicals. Due to common prevalence of occupational skin exposure and its health consequences it is necessary to look for efficient solutions allowing for reliable exposure assessment. The aim of the study is to present predictive models used to assess non-measured dermal exposure, as well as to acquaint Polish users with the principles of the selected model functioning...

Narratives of hope shape contemporary engagements with Parkinson's disease. On the one hand, a "biomedical narrative of hope" promises that biomedical research will help to transform this treatable but incurable disease into a curable one in the future. On the other hand, a more individual "illness narrative of hope" encourages patients to influence the course of Parkinson's disease by practicing self-care and positive thinking. This article asks how these two narratives of hope interact. It bases its argument on an analysis of data from 13 focus groups conducted in Germany in 2012 and 2014 with patients with Parkinson's disease and their relatives...

I will never forget the first time I stepped onto a ward as a nursing student in my freshly ironed new uniform. Everything was going well. This was it, I was living my dream. And then an older woman called out for a nurse, looked at me, and I froze. I wasn't a 'real' nurse, so what on earth was I to do?

A symptom being studied in the process of analysis can be seen as not unlike the unconscious affect it sprang from. The author presents a case in which a symptom, premature ejaculation, was analogous to the unconscious affect of guilt, which itself seemed to be a premature defensive transformation of a deeper current of anger. Guilt was interpreted as if it were a psychic premature ejaculation, a defensive derailment of anger. Fantasy and dream seemed to be engaged in similar transformations, with a fantasy of "premature incarceration" not unlike the symptom itself in its analogous functioning...

This article describes the future prospects of scientific dream research. Three frontiers of investigation hold special promise: neuroscientific studies of the brain-mind system's activities during sleep (such as during lucid dreaming); systematic analyses of large collections of dream reports from diverse populations of people; and psychotherapeutic explorations of the multiple dimensions of personal and collective meaning woven into the dream experiences of each individual. Several helpful books on the science of sleep and dreaming are mentioned for further study...

Downstream regulatory element antagonist modulator (DREAM) is an EF-hand Ca2+-binding protein that also binds to specific DNA sequence, downstream regulatory elements (DRE), and thereby regulates transcription in a calcium-dependent fashion. DREAM binds to DRE in the absence of Ca2+, but detaches from DRE under Ca2+ stimulation, allowing gene expression. The Ca2+-binding properties of DREAM and the consequences of the binding on protein structure are key to understanding the function of DREAM. Here we describe the application of hydrogen deuterium exchange mass spectrometry (HDX-MS) and site-directed mutagenesis to investigate the Ca2+ binding properties and the subsequent conformational changes of full length DREAM...

A resurgence of neurobiological and clinical research is currently underway into the therapeutic potential of serotonergic or 'classical' psychedelics, such as the prototypical psychedelic drug lysergic acid diethylamide (LSD), psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine), and ayahuasca - a betacarboline- and dimethyltryptamine (DMT)-containing Amazonian beverage. However, the mechanisms of therapeutic action are still not fully explained. Given that an altered state of consciousness is a common denominator that characterizes all classical psychedelics and given that both rapid eye movement sleep (REMS) and psychedelics modulate perception, mental imagery, emotion activation, fear memory extinction, and sense of self and body, in the present article, these two states of consciousness are systematically compared, and therapeutically relevant conclusions are drawn based on available evidence...

Adverse childhood experiences can deleteriously affect future physical and mental health, increasing risk for many illnesses, including psychiatric problems, sleep disorders, and, according to the present hypothesis, idiopathic nightmares. Much like post-traumatic nightmares, which are triggered by trauma and lead to recurrent emotional dreaming about the trauma, idiopathic nightmares are hypothesized to originate in early adverse experiences that lead in later life to the expression of early memories and emotions in dream content...

Where do our dreams originate from, and what do they tell us? Is there a universal set of symbols that are common to all dreams, regardless of a person's ethnicity or culture? What does dreaming reveal about the unconscious? Why do some dreams remain etched in our memories, whereas others are almost instantly forgotten? Some scientists have adopted the position that dreams are little more than noise in the brain, without any substantive purpose or function. Yet, such a stance seemingly runs counter to the experience of many people who reflect upon and even analyze their dreams, often in search of clues to their daily lives or insights into their deeper selves...

Half of all prostate cancers are caused by the TMPRSS2-ERG gene-fusion, which enables androgens to drive expression of the normally silent E26 transformation-specific (ETS) transcription factor ERG in prostate cells. Recent genomic landscape studies of such cancers have reported recurrent point mutations and focal deletions of another ETS member, the ETS2 repressor factor ERF. Here we show these ERF mutations cause decreased protein stability and mostly occur in tumours without ERG upregulation. ERF loss recapitulates the morphological and phenotypic features of ERG gain in normal mouse prostate cells, including expansion of the androgen receptor transcriptional repertoire, and ERF has tumour suppressor activity in the same genetic background of Pten loss that yields oncogenic activity by ERG...

The "bionic eye" - so long a dream of the future - is finally becoming a reality with retinal prostheses available to patients in both the US and Europe. However, clinical experience with these implants has made it apparent that the vision provided by these devices differs substantially from normal sight. Consequently, the ability to learn to make use of this abnormal retinal input plays a critical role in whether or not some functional vision is successfully regained. The goal of the present review is to summarize the vast basic science literature on developmental and adult cortical plasticity with an emphasis on how this literature might relate to the field of prosthetic vision...

BACKGROUND: The client experience is an important outcome in the evaluation and development of perinatal healthcare. But because clients meet different professionals, measuring such experiences poses a challenge. This is especially the case in the Netherlands, where pregnant women are often transferred between professionals due to the nation's approach to risk selection. This paper explores questions around how clients experience transfers of care during pregnancy, childbirth, and the neonatal period, as well as how these experiences compare to the established quality of care aspects the Dutch Patient Federation developed...

BACKGROUND: Earlier a century ago, Paul Ehrlich proposed an idea of a drug "magic bullet" that selectively eradicate diseased cells without harming the surrounding normal cells. OBJECTIVE: Since a lot of progress has been attained in this field to discover new horizons for targeted delivery of drug. As major problem in disease therapy is the severe toxic effects of prescribed drugs on healthy cells. In order to reduce the adverse effects of chemotherapy on healthy tissues, herein, we summaries the use of recent drug delivery systems for targeted therapy...
