CLEM (correlated light and electron microscope) imaging is a highly useful technique for examining primary cilia. With CLEM, it is possible to determine the distribution of tagged proteins along the ciliary membrane and axoneme with high precision. Scanning electron microscopy (SEM) permits measurement of ciliary length and orientation in relation to nearby cellular structures in a 3D image; in optimal cases, this can be combined with superresolution microscopy of selected ciliary components as they enter or leave the cilium...

Autophagy is a catabolic pathway for the degradation and recycling of intracellular components, contributing to maintain cell homeostasis. Changes in autophagy activity can be monitored by a variety of biochemical and functional assays that should be used in combination. Recently, it has been described that signaling from the primary cilium modulates autophagy. This novel and reciprocal interaction will impact diverse aspects of the cell biology in healthy and pathophysiological conditions. Here, we describe methods to monitor autophagy activity in cilia mutants, as well as the use of autophagy mutants to monitor ciliogenesis...

New heart failure guidelines have been issued during the past several months, both in the United States and in Europe, in response to recent advances in and the approval of new drugs for the treatment of heart failure. Although guidelines documents are often viewed as authoritative and purely evidence-based, there are replete with meaningful (and inexplicable) inconsistencies, which derive from a review of the same body of scientific data by different groups. This satirical review highlights several examples of the entertaining foolishness of recent guideline documents in the good-natured hope that physicians will understand what the guidelines are, and more importantly, what they are not...

Amyloid precursor protein (APP) and its cleavage product amyloid β (Aβ) have been thoroughly studied in Alzheimer's disease. However, APP also appears to be important for neuronal development. Differentiation of induced pluripotent stem cells (iPSCs) towards cortical neurons enables in vitro mechanistic studies on human neuronal development. Here, we investigated expression and proteolytic processing of APP during differentiation of human iPSCs towards cortical neurons over a 100-day period. APP expression remained stable during neuronal differentiation, whereas APP processing changed...

Architectonic embodiment postulates a bidirectional link between bodily awareness and the architectural environment. The standard size and features of the human body, for instance, are thought to influence the structure of interiors and buildings, as well as their perception and appreciation. Whereas architectural practice and theory, the visual arts and more recently the cognitive sciences have explored this relationship of humans with their crafted environments, many fictional literary works have long experimented with alterations of body-environment scaling...

Conventional amplitude and phase modulated pulse sequences for selective imaging of nonlinear tissue and ultrasound contrast agents are designed for piezoelectric transducers that behave linearly. Inherent nonlinearity of capacitive micromachined ultrasonic transducers (CMUTs), especially during large-signal operation, renders these methods inapplicable. In this paper, we present different pulse sequences for nonlinear imaging that are valid for small- and large-signal CMUT operations. For small-signal operation, two-pulse amplitude and phase modulation methods for microbubble and tissue harmonic imaging are presented, where CMUT nonlinearity is compensated via subharmonic excitation...

"Orandum est ut sit mens sana in corpore sano" ("You should pray for a healthy mind in a healthy body"). This phrase is a shortened citation from the satirical work of the Roman poet Juvenal. It highlights the significant role of physical as well as mental health. Aesthetic ideals have existed since the Archaic age, but they are not necessarily the same in different continents. Being familiar with aesthetic ideals in different cultures might help to accommodate patients' needs and wishes in today's globalised world...

Online communities, created and sustained by people sharing and discussing texts on the internet, play an increasingly important role in social health movements. In this essay, we explore a collective mobilization in miniature through an in-depth analysis of two satiric texts from an online community for people with myalgic encephalomyelitis (ME). By blending a sociological analysis with a rhetorical exploration of these texts, our aim is to grasp the discursive generation of a social movement online community set up by sufferers themselves to negotiate and contest the dominating biomedical perception of their condition...

The motile cilium is a mechanical wonder, a cellular nanomachine that produces a high-speed beat based on a cycle of bends that move along an axoneme made of 9+2 microtubules. The molecular motors, dyneins, power the ciliary beat. The dyneins are compacted into inner and outer dynein arms, whose activity is highly regulated to produce microtubule sliding and axonemal bending. The switch point hypothesis was developed long ago to account for how sliding in the presence of axonemal radial spoke-central pair interactions causes the ciliary beat...

This essay argues that the foundational traumatic lacuna behind John Lydgate's Danse Macabre is the social agon between those who wage the Hundred Years War and those who fight in it. Drawing from the insights of trauma theory to discuss the poem's form, the essay uncovers Lydgate's persistent concern with the damage caused by the war and the concomitant political unrest it causes. It argues further that Lydgate theorized this agon using the emergent genre of tragedy, which is beginning to be practiced anew in late-medieval England...

Plasma cathodes are insert free devices that are developed to be employed as electron sources in electric propulsion and ion source applications as practical alternatives to more commonly used hollow cathodes. Inductively coupled plasma cathodes, or Radio Frequency (RF) plasma cathodes, are introduced in recent years. Because of its compact geometry, and simple and efficient plasma generation, RF plasma source is considered to be suitable for plasma cathode applications. In this study, numerous RF plasma cathodes have been designed and manufactured...

Virginia Satir continues to be a highly influential figure in family therapy. The summation of her decades of work with families, the Satir growth model (SGM), remains a relevant therapeutic approach that is still practiced by many. This narrative review sought to examine (a) the core therapeutic methods developed by Satir for working with families, and (b) the empirical evidence to support the use of such methods. The author reviewed both firsthand and secondhand accounts of Satir's model of therapy, as well as extant research...

Neoplasms with a myopericytomatous pattern represent a morphological spectrum of lesions encompassing myopericytoma of the skin and soft tissue, angioleiomyoma, myofibromatosis/infantile haemangiopericytoma and putative neoplasms reported as malignant myopericytoma. Lack of reproducible phenotypic and genetic features of malignant myopericytic neoplasms have prevented the establishment of myopericytic sarcoma as an acceptable diagnostic category. Following detection of a LMNA-NTRK1 gene fusion in an index case of paediatric haemangiopericytoma-like sarcoma by combined whole-genome and RNA sequencing, we identified three additional sarcomas harbouring NTRK1 gene fusions, termed 'spindle cell sarcoma, NOS with myo/haemangiopericytic growth pattern'...

This article addresses the question of the limits of literate medicine in Europe, through an examination of the Russian literate medical world of the late seventeenth and early eighteenth centuries. Russian courtly medicine had been dominated by Western Europeans from the 1480s, but in the early eighteenth century new licensing arrangements solidified the presence of these foreigners in the wider Russian medical world. Foreign medical practitioners took advantage of this development, aiming works at an increasingly large proportion of Russian literate society...

OBJECTIVE: A subset of individuals with bulimia nervosa (BN) have borderline personality disorder (BPD) symptoms, including chronic negative affect and interpersonal problems. These symptoms predict poor BN treatment outcome in some studies. The broad version of Enhanced Cognitive Behavior Therapy (CBT-E) was developed to address co-occurring problems that interfere with treatment response. The current study investigated the relative effects, predictors, and moderators of CBT-E for BN with BPD and co-occurring mood/anxiety disorders...

We present a nonlinear lumped model that predicts the electrical input-output behavior of an ultrasonic system using CMUTs with arbitrary array/membrane/electrode geometry in different transmit-receive configurations and drive signals. The receive-only operation, where the electrical output signal of the CMUT array in response to incident pressure field is calculated, is included by modifying the boundary elementbased vibroacoustic formulation for a CMUT array in rigid baffle. Along with the accurate large signal transmit model, this formulation covers pitch-catch and pulse-echo operation when transmit and receive signals can be separated in time...

Sense of humor is potentially relevant to social functioning in dementias, but has been little studied in these diseases. We designed a semi-structured informant questionnaire to assess humor behavior and preferences in patients with behavioral variant frontotemporal dementia (bvFTD; n = 15), semantic dementia (SD; n = 7), progressive nonfluent aphasia (PNFA; n = 10), and Alzheimer's disease (AD; n = 16) versus healthy age-matched individuals (n = 21). Altered (including frankly inappropriate) humor responses were significantly more frequent in bvFTD and SD (all patients) than PNFA or AD (around 40% of patients)...
