Caveolae and associated cavin and caveolins may govern myocardial function, together with responses to mechanical and ischaemic stresses. Abnormalities in these proteins are also implicated in different cardiovascular disorders. However, specific roles of the cavin-1 protein in cardiac and coronary responses to mechanical/metabolic perturbation remain unclear. We characterised cardiovascular impacts of cavin-1 deficiency, comparing myocardial and coronary phenotypes and responses to stretch and ischaemia-reperfusion in hearts from cavin-1 (+/+) and cavin-1 (-/-) mice...

This article proposes a reflection on the exclusion of particularly vulnerable human beings as a condition for the success of economistic culture and social organization. This fragility can depend on the body side as well as the social aspect: the effects of discrimination are identical. To react to a situation of injustice less and less tolerable, the biolaw touches -as in general the right, if it has a meaning and a specific function, and is not reduced to mere legitimization of the balance of forces or interest of the individuals or the groups better organized and represented- defend the fragility of all violence in the name of equality among human beings which depend on the universal condition of vulnerability, held in its positive aspects by philosophers such as MacIntyre and Nussbaum and many literary geniuses of all times...

The ability to adapt walking to environmental circumstances is an important aspect of walking, yet difficult to assess. The Interactive Walkway was developed to assess walking adaptability by augmenting a multi-Kinect-v2 10-m walkway with gait-dependent visual context (stepping targets, obstacles) using real-time processed markerless full-body kinematics. In this study we determined Interactive Walkway's usability for walking-adaptability assessments in terms of between-systems agreement and sensitivity to task and subject variations...

We present a dynamic and thermodynamic study of the orientational glass former Freon 113 (1,1,2-trichloro-1,2,2-trifluoroethane, CCl_{2}F-CClF_{2}) in order to analyze its kinetic and thermodynamic fragilities. Freon 113 displays internal molecular degrees of freedom that promote a complex energy landscape. Experimental specific heat and its microscopic origin, the vibrational density of states from inelastic neutron scattering, together with the orientational dynamics obtained by means of dielectric spectroscopy have revealed the highest fragility value, both thermodynamic and kinetic, found for this orientational glass former...

Cardiopathies and osteoporosis are inter-related due to pathogenetic, hormonal, genetic features as well as an increased risk of fragility. An important feature is attributed to the process of atherosclerosis, which is responsible for an osteopenia effect and degeneration of vascular walls. To date the study populations have been limited. To verify the incidence of cardio-vascular disease in a larger osteoporotic population, we designed a retrospective clinical study analyzing the “Hospital Discharge Data” (HDD) in Apulia between 2006 and 2010...

OBJECTIVE: Surgical resection of a brain arteriovenous malformation (AVM) poses a technical challenge due to the fragility and number of small feeding and draining vessels around the nidus. Acquiring knowledge of optimal force applied to such tissue is important in surgical performance and education. METHODS: A force sensing bipolar forceps was developed through installation of strain gauge sensors, and force profiles were obtained from two AVM surgeries. The force data associated with vessel injury, unsuccessful trial, was compared with that from successful trials...

BACKGROUND: Fragile X Syndrome (FXS) is the main genetic cause of autism and intellectual deficiency resulting the absence of the Fragile X Mental Retardation Protein (FMRP). Clinical picture is characterized by cognitive impairment associated with a broad spectrum of psychiatric comorbidities including autism spectrum disorders and attention-deficit/hyperactivity disorders. Some of these disorders have been associated with lipid abnormalities and lower cholesterol levels. Since lipids are important for neuronal development, we aim to investigate the lipid profile of French Canadian-FXS individuals and to identify the altered components of cholesterol metabolism as well as their association with clinical profile...

Fragile X Syndrome (FXS) is a neurodevelopmental genetic disorder associated with cognitive and behavioural deficits. In particular, neuronal habituation processes have been shown to be altered in FXS patients. Yet, while such deficits have been primarily explored using auditory stimuli, less is known in the visual modality. Here, we investigated the putative alteration of repetition suppression using faces in FXS patients compared to controls that had the same age distribution. Electroencephalographic (EEG) signals were acquired while participants were presented with 18 different faces, each repeated ten times successively...

Synaptic protein synthesis is essential for modification of the brain by experience and is aberrant in several genetically defined disorders, notably fragile X (FX), a heritable cause of autism and intellectual disability. Neural activity directs local protein synthesis via activation of metabotropic glutamate receptor 5 (mGlu5), yet how mGlu5 couples to the intracellular signaling pathways that regulate mRNA translation is poorly understood. Here, we provide evidence that β-arrestin2 mediates mGlu5-stimulated protein synthesis in the hippocampus and show that genetic reduction of β-arrestin2 corrects aberrant synaptic plasticity and cognition in the Fmr1(-/y) mouse model of FX...

Lee Jussim
In my Précis of Social Perception and Social Reality (Jussim 2012, henceforth abbreviated as SPSR), I argued that the social science scholarship on social perception and interpersonal expectancies was characterized by a tripartite pattern: (1) Errors, biases, and self-fulfilling prophecies in person perception were generally weak, fragile, and fleeting; (2) Social perceptions were often quite accurate; and (3) Conclusions appearing throughout the social psychology scientific literature routinely overstated the power and pervasiveness of expectancy effects, and ignored evidence of accuracy...

I suggest two ways in which Jussim's extensive discussion (in his 2012 book) could be enriched: first, by exploring the distinction between perceptual judgments and interpretive judgments; second, by considering the power of expectations to be self-fulfilling in the case of young children and the case of fragile egos.

BACKGROUND: Critical illness is associated with increased risk of fragility fracture and loss of bone mineral density (BMD), although the impact of medication exposures (bone anti-fracture therapy or glucocorticoids) and time remain unexplored. The objective of this study was to describe the association of time after ICU admission, and post-ICU administration of bone anti-fracture therapy or glucocorticoids after critical illness, with change in BMD. METHODS: In this prospective observational study, conducted in a tertiary hospital ICU, we studied adult patients requiring mechanical ventilation for at least 24 hours and measured BMD annually for 2 years after ICU discharge...
