We have successfully prepared and structurally characterized a family of butterfly-like [CoLn] complexes where all magnetic properties are due to the Ln(iii) ions. The complexes with Ln = Tb(1), Dy(2), Ho(3), Er(4) and Yb(5) are iso-structural. An exception is the complex with Ln = Gd(6) which strings in a one dimensional chain. The structural similarity together with the high tendency of the crystallites to align under an applied magnetic field allowed an overall DC magnetic data treatment to extract phenomenological crystal field parameters and hence to determine the ground state multiplet energy level splitting...

BACKGROUND: Midbrain dopaminergic neurons code a computational quantity, reward prediction error (RPE), which has been causally related to learning. Recently, this insight has been leveraged to link phenomenological and biological levels of understanding in psychiatric disorders, such as schizophrenia. However, results have been mixed, possibly due to small sample sizes. Here we present results from two studies with relatively large Ns to assess VS RPE in schizophrenia. METHODS: In the current study we analyzed data from two independent studies, involving a total of 87 chronic medicated schizophrenia patients and 61 controls...

PURPOSE: The increasing rates of early-onset breast cancer (BC) and of woman survival render fertility preservation (FP) a pressing issue. We probe women's experiences of FP counseling and decision making, aiming to identify emergent counseling patterns. METHODS: Semi-structured interviews were conducted with 16 women, who had been diagnosed with BC at the ages of 24-38, 1 to 5 years prior to the interview. BC survivors were recruited through posts in online fora, consented to participate, and were invited to tell their FP stories...

BACKGROUND: Recent advances in our understanding of the neurobiology of tics have led to the development of novel rodent models capturing different pathophysiological and phenotypic aspects of Tourette syndrome. The proliferation of these models, however, raises vexing questions on what standards should be adopted to assess their theoretical validity and empirical utility. Assessing the homology of a rodent motoric burst with a tic remains problematic, due to our incomplete knowledge of the underpinnings of tics, their high phenotypic complexity and variability, limitations in our ability test key aspects of tic phenomenology (such as premonitory sensory phenomena) in animals, and between-species differences in neuroanatomy and behavioral repertoire...

OBJECTIVES: The first objective of this article is to summarize the history of electroconvulsive therapy (ECT) in psychiatry in order to highlight the transition from clinical level of evidence based on phenomenological descriptions to controlled trial establishing causal relationship. The second objective is to apply the criteria of causation for ECT, to focus on the dose-effect relationship criteria, and thus to analyze the conditions of application of these criteria for ECT. METHODS: A literature review exploring the use of electricity, ECT and electroencephalography (EEG) in psychiatry was conducted...

LSD (lysergic acid diethylamide) is a model psychedelic drug used to study mechanism underlying the effects induced by hallucinogens. However, despite advanced knowledge about molecular mechanism responsible for the effects induced by LSD and other related substances acting at serotonergic 5-HT2a receptors, we still do not understand how these drugs trigger specific sensory experiences. LSD-induced experience is characterised by perception of movement in the environment and by presence of various bodily sensations such as floating in space, merging into surroundings and movement out of the physical body (the out-of-body experience)...

Despite the brain's immense processing power, it has finite resources. Where do these resource limits come from? Little research has examined possible low-level sensory contributions to these limitations. Mental imagery is a fundamental part of human cognition that bridges cognition with sensory representations. Hence, imagery serves as a good candidate sensory process for probing how low capacity limitations might extend down the processing hierarchy. Here we introduce a novel technique to measure the sensory capacity of mental imagery, while removing the need for memory and any direct subjective reports...

AIMS AND OBJECTIVES: The objective of this study was to describe the lived experience of recovery during the first six months after colorectal cancer surgery. BACKGROUND: Colorectal cancer is the third most common cancer-diagnose worldwide. Early discharge places demands on health care professionals to prepare patients for their return home and to provide them with appropriate support throughout the recovery process. This requires knowledge of what it is like to recover from colorectal cancer surgery...

BACKGROUND: Despite the rising incidence of melanoma, medical students have progressively fewer opportunities to encounter patients with this important condition. Curricula tend to attach the greatest value to intellectual forms of learning. Compared to intellectual learning, however, experiential learning affords students deep insights about a condition. Doctors who experience ill health are more empathic towards patients. However opportunities to learn about cancer experientially are limited...

We investigate the metallic phases observed in hybrid metal-GaAs nanowire devices obtained by controlled thermal annealing of Ni/Au electrodes. Devices are fabricated onto a SiN membrane compatible with transmission electron microscopy studies. Energy dispersive X-ray spectroscopy allows us to show that the nanowire body includes two Ni-rich phases that, thanks to an innovative use of electron diffraction tomography, can be unambiguously identified as Ni3GaAs and Ni5As2 crystals. The mechanisms of Ni incorporation leading to the observed phenomenology are discussed...

Previous research using stepwise regression analyses found self-reported hypnotic depth (srHD) to be a function of suggestibility, trance state effects, and expectancy. This study sought to replicate and expand that research using a general state measure of hypnotic responsivity, the Phenomenology of Consciousness Inventory: Hypnotic Assessment Procedure (PCI-HAP). Ninety-five participants completed an Italian translation of the PCI-HAP, with srHD scores predicted from the PCI-HAP assessment items. The regression analysis replicated the previous research results...

Hypnosis and meditation, as a whole, form a heterogeneous complex of psychosomatic techniques able to control mind and body regulation. Hypnosis has been pragmatically used for limited therapeutic targets, while Eastern meditation has much wider philosophical and existential implications, aiming for a radical liberation from all illusions, attachments, suffering and pain. The available data on the history, phenomenology, and neuropsychology of hypnosis and meditation show several common features, such as the following: (a) induction based on focused attention; (b) capability to reach an intentional control of both biologic-somatic activities and conscious-unconscious processes;...

CONTEXT: An increasing number of medical schools around the world are implementing longitudinal integrated clerkships (LICs). The University of Alberta's third-year LIC admits a small group of each class. Those not in the LIC undertake a rotation-based clerkship (RBC). All students have a fourth-year RBC. Meaningful participation in patient care and guidance have been identified as affordances for work-based learning. METHODS: This qualitative study is part of an ongoing research programme conducted in a hermeneutic phenomenological frame...

Ping Lu, Renliang Yuan, Jian Min Zuo
Elemental mapping at the atomic-scale by scanning transmission electron microscopy (STEM) using energy-dispersive X-ray spectroscopy (EDS) provides a powerful real-space approach to chemical characterization of crystal structures. However, applications of this powerful technique have been limited by inefficient X-ray emission and collection, which require long acquisition times. Recently, using a lattice-vector translation method, we have shown that rapid atomic-scale elemental mapping using STEM-EDS can be achieved...

Since the appearance of schizophrenia as a distinct diagnosis, various researchers and clinicians, particularly those in the phenomenological and existential tradition, have noted the unique contribution of attitudinal and characterological factors to the illness. There has been a notable lack of attention paid to these features in most recent research on the disorder; still, understanding the values, attitudes, and worldviews - what might be termed the "existential orientation" - of persons with schizophrenia may be essential for comprehending the illness and developing effective approaches to treatment...

Changes in the sense of agency are defining feature of hypnosis. The Sense of Agency Rating Scale (SOARS) is a 10-item questionnaire, administered after a hypnosis session to assess alteration in the sense of agency. In the present study, a Hungarian version of the measure (SOARS-HU) is presented. The SOARS-HU and the Phenomenology of Consciousness Inventory (PCI) were administered to 197 subjects following hypnotizability screening with the Harvard Group Scale of Hypnotic Susceptibility Scale, Form A (HGSHS:A)...

Because of the ethical and regulatory hurdles associated with human studies, much of what is known about the psychopharmacology of hallucinogens has been derived from animal models. However, developing reliable animal models has proven to be a challenging task due to the complexity and variability of hallucinogen effects in humans. This chapter focuses on three animal models that are frequently used to test the effects of hallucinogens on unconditioned behavior: head twitch response (HTR), prepulse inhibition of startle (PPI), and exploratory behavior...

BACKGROUND: Resilience is a key factor in improving health and attenuating problems caused by chronic diseases in the elderly. Having a clear understanding of its meaning in a specific population can be of great help in taking efficient steps toward better health services. Given the lack of information in this regard, the aim of this study was to understand the meaning of resilience for hospitalized older people who experience chronic conditions. METHODS: The study was carried out as a qualitative work based on a descriptive phenomenological approach...
