#1
REVIEW
Jonathan D Power, Bradley L Schlaggar
An essential feature of the brain is its capacity to change. Neuroscientists use the term 'plasticity' to describe the malleability of neuronal connectivity and circuitry. How does plasticity work? A review of current data suggests that plasticity encompasses many distinct phenomena, some of which operate across most or all of the lifespan, and others that operate exclusively in early development. This essay surveys some of the key concepts related to neural plasticity, beginning with how current patterns of neural activity (e...

The detection of fetal anomalies has improved in the last years as a result of the generalization of ultrasound pregnancy screening exams. The presence of a cystic imaging in the fetal pelvis is a relatively common finding, which can correspond to a real congenital cystic lesion or result from the anomalous liquid accumulation in a whole pelvic organ, mainly the urinary bladder, the uterus, or the vagina. In selected cases with poor prognosis and/or inconclusive echographic findings, magnetic resonance may bring additional information in terms of the characterization, anatomical location, and real extension of the pathology...

Radiofrequency (RF) ablation requires a complex set of devices as well as profound electrophysiological experience and substantial knowledge of physical science basics. To establish RF ablation in-vitro teaching-system, six workstations were equipped with computer-controlled RF ablation generators. Universal connection boxes allow ablation-essays with catheters of different make and model. Special wetlabs were developed combining a basin containing isotonic saline solution with a thermostat and a pump to simulate blood flow...

The clonal evolution of Trypanosoma cruzi sustains scientifically the hypothesis of association between parasite's genetic, biological behavior and possibly the clinical aspects of Chagas disease in patients from whom they were isolated. This study intended to characterize a range of biological properties of TcI, TcII and TcVI T. cruzi samples in order to verify the existence of these associations. Several biological features were evaluated, including in vitro epimastigote-growth, "Vero"cells infectivity and growth, along with in vivo studies of parasitemia, polymorphism of trypomastigotes, cardiac inflammation, fibrosis and response to treatment by nifurtimox during the acute and chronic murine infection...

REVIEW

The adult human brain is arguably the most complex of biological systems. It contains 86 billion neurons (the information processing cells of the brain) and many more support cells. The neurons, with the assistance of the support cells, form trillions of connections creating complex, interconnected neural networks that support all human thought, feeling, and action. A challenge for modern neuroscience is to provide a model that accounts for this exquisitely complex and dynamic system. One fundamental part of this model is an account of how the human brain develops...

Patellar fractures account for approximately 1% of all skeletal fractures and may result from direct, indirect, or combined trauma. Because of the importance of patellar integrity for knee extension and the risk of associated injury to the extensor mechanism, accurate reporting and description of fracture type is paramount for appropriate management. This pictorial essay aims to review the normal anatomy of the patella, the mechanisms of injury and different types of patellar fractures, with a brief introduction to therapeutic management...

REVIEW
Christian J C Biscombe
Electro-osmosis and electrophoresis were discovered by F. F. Reuss in Moscow in 1807. Or so the story goes. This essay critically examines the contributions of three scientists to the discovery of electrokinetic phenomena. The evidence suggests that Reuss did indeed discover electro-osmosis, which takes its name (indirectly) from the work of Porrett. Contrary to current consensus, Gautherot made the earliest known observation of electrophoresis.

It is easy to rush to judgement about students who cheat in their exams or buy essays on the internet. Such activities can never be condoned and those who succumb to temptation must suffer the consequences, which can involve being removed from their courses.

Chiara Russo Krauss
This essay provides a fresh account of the break between Oswald Külpe and his master Wilhelm Wundt. Kurt Danziger's reconstruction of the "repudiation" of Wundt, which has become the canon for this significant episode of history of psychology, focused on the supposed influence of Ernst Mach on this set of events, overshadowing the other exponent of Empiriocriticism: Richard Avenarius. Analyzing archival documents and examining anew the primary sources, the paper shows that Avenarius was himself a member of Wundt's circle, and that his "repudiation" of the master paved the way for Külpe...

Although contemporary psychoanalysis is split into different schools and traditions, there is growing support for some of the main tenets of contemporary psychodynamic thinking from attachment theory, infant research, developmental psychopathology, new models of motivation, the neuroscience of emotions and emotional regulation, and the discovery of different implicit and explicit memory systems. These tenets, which psychodynamic clinicians of all stripes encounter in their daily work with clients, are the following: (1) that large footprints are left over from infancy and childhood which involved insensitive, intrusive, frightening, or shaming care; (2) the carryover of these relational experiences into adulthood are expressed as unconscious expectations and attributions we make of others (transference and countertransference; (3) defensive processes and emotional regulation and deregulatory patterns develop to cope with these unhealthy relations...

BACKGROUND: Over recent years there has been an increase in teaching of both palliative care and reflective practice in UK medical schools. The palliative care teaching at the University of Cambridge School of Clinical Medicine is multi-faceted and involves students writing reflective essays after individually meeting patients approaching the end of life during their final year general practice and hospital medicine placements. This paper draws on two studies examining this teaching element to analyse what the students found valuable about it and to comment on the practice of meeting patients and subsequent reflective writing...

Anorectal disorders are a common cause of presentation to the emergency department (ED). While the most frequently encountered anorectal conditions, such as hemorrhoids and anal fissures, are relatively benign and do not require imaging for diagnosis or management, there are multiple potentially life threatening anorectal conditions for which imaging is an important component of evaluation, diagnosis, and management. Although computed tomography (CT) is the most commonly used imaging modality for evaluation of anorectal pathology in the ED, magnetic resonance imaging (MRI) has an increasingly important role in the detection, characterization and management of specific anorectal conditions...

Medical students across the USA have increasingly made the medical institution a place for speculating racially just futures. From die-ins in Fall 2014 to silent protests in response to racially motivated police brutality, medical schools have responded to the public health crisis that is racial injustice in the USA. Reading science fiction may benefit healthcare practitioners who are already invested in imagining a more just, healthier futurity. Fiction that rewrites the future in ways that undermine contemporary power regimes has been termed 'visionary fiction'...

Erika Lorraine Milam
Throughout the twentieth century, contemporary understandings of evolutionary theory were tightly linked to visions of the future freighted with moral consequence. This essay traces the origins and legacy of this scientific commitment to a universal family of man in postwar evolutionary theory, and elaborates how evolutionary scientists sought to reframe the politics of human evolution by claiming that the principles governing the physical past of humanity differed fundamentally from those that would matter in the coming decades, centuries, or even millennia...

Jazz cats use the term 'woodshedding' to denote a period of intense practice during which they aim to take their playing up a few notches. Developing expertise, whether we are speaking musically or talking about communicating with patients, requires a lifelong commitment to such practice. For physicians, the woodshed is not a practice room or an isolated space. No: clinical environments are the woodsheds; they are the only places in which one can hone communication skills. The idea of 'shedding' in the setting of routine practice challenges prevailing notions about communication skills training and has implications for how such skills should be learned, nurtured and assessed...

The advancement of knowledge and development of policy in the field of medical education require critical academic discourse among the most intelligent medical educators; and critical academic discourse requires coffee. In this essay, we reflect on the state of professional development conferences in the field of medical education and the rituals that surround their success. Having begun in ancient Greece, symposia were ripe with debauchery. Today, sedated by the light brown walls of hotel conference centres, symposia are more serious endeavours, engaging men and women in the sometimes turbulent waters of epistemological debate...

In this essay the term 'scene' which has been developed in the German psychoanalytic discussion, is confronted with the terms 'total situation' and 'psychoanalytic field', showing common features as well as differences. Thereafter four child observations are presented, through which light is thrown onto the scenic structures which make the foundations of early experience. In the precedence of scenes those structures are omnipresent whereas subjectivity only gradually builds up. It is shown how the development of subjectivity and the differentiation of consciousness and unconscious go along with overcoming the precedence of scenes, by breaking them up and reorganizing them...
