miR-223: An inflammatory oncomiR enters the cardiovascular field

AbstractMicroRNAs (miRNAs) are small, noncoding RNAs of 18–22 nucleotides in length that regulate post-transcriptional expression by base-pairing with target mRNAs. It is now clearly established that miRNAs are involved in most of the cell's physiopathological processes (including carcinogenesis and metabolic disorders). This review focuses on miR-223, which was first described as a modulator of hematopoietic lineage differentiation. We outline the role of miR-223 deregulation in several types of cancers and highlight its inclusion in a newly identified and fast-growing family of miRNAs called oncomiRs. We then look at miR-223's emerging role in inflammatory and metabolic disorders, with a particular focus on muscle diseases, type II diabetes, atherosclerosis and vascular calcification. miR-223 is one of the growing number of RNA biomarkers of various human metabolic diseases and is thus of special interest to both researchers and clinicians in the cardiovascular field

The Effects Of A 4-Week Resistance Training Intervention On Cardiovascular And Autonomic Function In Young Women

PURPOSE: Cardiovascular disease is growing in prevalence, and the cardiovascular and autonomic protective properties of estrogen in women are no longer keeping up with the lifestyle habits and risk factors increasing this disease risk. While aerobic training has been shown to promote increased cardiovascular health and autonomic function, little is known about the effects of resistance training. METHODS: Nine women were recruited to participate in a 4-week strength-based resistance training intervention following a 4-week wait period. Subjects arrived to the lab for baseline measurements of anthropometrics, body composition, cardiovascular function, and autonomic function. Subjects were asked to attend baseline measurements, familiarization, and maximal effort strength test pre-wait period, post-wait period/pre-intervention, and post-intervention. RESULTS: There was a significant increase in strength gains for squat, bench, and deadlift, pre- to post-intervention (p=0.000, p=0.002, and p=0.000, respectively). There was a significant increase in resting heart rate pre- to post-intervention (p=0.017). A significant decrease was observed in both baroreceptor sensitivity and total peripheral resistance pre- to post-intervention (p=0.018 and p=0.002, respectively). CONCLUSION: Four weeks of a strength-based resistance training intervention promoted strength gains in young women without eliciting deleterious effects in cardiovascular and autonomic function

AAAI: an Argument Against Artificial Intelligence

The ethical concerns regarding the successful development of an Artificial Intelligence have received a lot of attention lately. The idea is that even if we have good reason to believe that it is very unlikely, the mere possibility of an AI causing extreme human suffering is important enough to warrant serious consideration. Others look at this problem from the opposite perspective, namely that of the AI itself. Here the idea is that even if we have good reason to believe that it is very unlikely, the mere possibility of humanity causing extreme suffering to an AI is important enough to warrant serious consideration. This paper starts from the observation that both concerns rely on problematic philosophical assumptions. Rather than tackling these assumptions directly, it proceeds to present an argument that if one takes these assumptions seriously, then one has a moral obligation to advocate for a ban on the development of a conscious AI

Curriculum Transformation: Redesigning a Construction Management program to a Vertically and Horizontally Integrated Curriculum with Authentic Project-Based Learning

Short Abstract: The Construction Management program at Purdue University is redesigning their curriculum to a vertically and horizontally integrated program. The curriculum will utilize authentic projects from industry partners, providing a basis for project-based learning and instruction. All faculty will team-teach the large project based courses developed for the new curriculum. Full Abstract: Traditional higher education provides students with a variety of specialized courses, combined to create a curriculum, which then translates into a major area of study. While prerequisites and course numbers provide a road map to the students for the order of classes, there is no guarantee the concepts from one course are built upon by another course. Typically, a senior capstone is the first time students are required to synthesize accumulated skills and knowledge. For the past two years, the Construction Management program at Purdue University has been redesigning their curriculum to integrate construction concepts both vertically and horizontally throughout the entire 4-year program. The new curriculum will also utilize authentic projects obtained from industry partners, which will provide the basis of the project-based learning and instruction. Team teaching by all faculty within the department will be applied in the large project based courses. While the technical information presented will remain the same, it is the hope of the faculty this new curriculum will develop students who are better prepared for the construction industry by having a higher level of written and verbal communication, increased critical thinking and problem solving skills, and display greater professionalism and initiative

Consciousness, Action Selection, Meaning and Phenomenic Anticipation

Phenomenal states are generally considered the ultimate sources of intrinsic motivation for autonomous biological agents. In this article, we will address the issue of the necessity of exploiting these states for the design and implementation of robust goal-directed artificial systems. We will provide an analysis of consciousness in terms of a precise definition of how an agent "understands" the informational flows entering the agent and its very own action possibilities. This abstract model of consciousness and understanding will be based in the analysis and evaluation of phenomenal states along potential future trajectories in the state space of the agents. This implies that a potential strategy to follow in order to build autonomous but still customer-useful systems is to embed them with the particular, ad hoc phenomenality that captures the system-external requirements that define the system usefulness from a customer-based, requirements-strict engineering viewpoint

The death and the resurrection of (psy)critique: the case of neuroeducation

A rapidly emerging hegemonic neuro-culture and a booming neural subjectivity signal the entry point for an inquiry into the status of the signifier neuro as a universal passe-partout. The wager of this paper is that the various (mis)appropriations of the neurosciences in the media and in academia itself point to something essential, if not structural, in connection with both the discipline of the neurosciences and the current socio-cultural and ideological climate. Starting from the case of neuroeducation (the application of neuroscience within education), the genealogy of the neurological turn is linked to the history of psychology and its inextricable bond with processes of psychologisation. If the neurological turn risks not merely neglecting the dimension of critique, but also obviating its possibility, then revivifying a psy-critique (understanding the academified modern subject as grounded in the scientific point of view from nowhere) might be necessary in order to understand today’s neural subjectivity and its place within current biopolitics

I Me Mine: on a Confusion Concerning the Subjective Character of Experience

In recent debates on phenomenal consciousness, a distinction is sometimes made, after Levine (2001) and Kriegel (2009), between the “qualitative character” of an experience, i.e. the specific way it feels to the subject (e.g. blueish or sweetish or pleasant), and its “subjective character”, i.e. the fact that there is anything at all that it feels like to her. I argue that much discussion of subjective character is affected by a conflation between three different notions. I start by disentangling the three notions in question, under the labels of “for-me-ness”, “me-ness” and “mineness”. Next, I argue that these notions are not equivalent; in particular, there is no conceptual implication from for-me-ness to me-ness or mineness. Empirical considerations based on clinical cases additionally suggest that the three notions may also correspond to different properties (although the claim of conceptual non-equivalence does not depend on this further point). The aim is clarificatory, cautionary but also critical: I examine four existing arguments from subjective character that are fuelled by an undifferentiated use of the three notions, and find them to be flawed for this reason

Embodying the mind and representing the body

Does the existence of body representations undermine the explanatory role of the body? Or do certain types of representation depend so closely upon the body that their involvement in a cognitive task implicates the body itself? In the introduction of this special issue we explore lines of tension and complement that might hold between the notions of embodiment and body representations, which remain too often neglected or obscure. To do so, we distinguish two conceptions of embodiment that either put weight on the explanatory role of the body itself or body representations. We further analyse how and to what extent body representations can be said to be embodied. Finally, we give an overview of the full volume articulated around foundational issues (How should we define the notion of embodiment? To what extent and in what sense is embodiment compatible with representationalism? To what extent and in what sense are sensorimotor approaches similar to behaviourism?) and their applications in several cognitive domains (perception, concepts, selfhood, social cognition)

Keeping in Touch with One's Self: Multisensory Mechanisms of Self-Consciousness

BACKGROUND: The spatial unity between self and body can be disrupted by employing conflicting visual-somatosensory bodily input, thereby bringing neurological observations on bodily self-consciousness under scientific scrutiny. Here we designed a novel paradigm linking the study of bodily self-consciousness to the spatial representation of visuo-tactile stimuli by measuring crossmodal congruency effects (CCEs) for the full body. METHODOLOGY/PRINCIPAL FINDINGS: We measured full body CCEs by attaching four vibrator-light pairs to the trunks (backs) of subjects who viewed their bodies from behind via a camera and a head mounted display (HMD). Subjects made speeded elevation (up/down) judgments of the tactile stimuli while ignoring light stimuli. To modulate self-identification for the seen body subjects were stroked on their backs with a stick and the felt stroking was either synchronous or asynchronous with the stroking that could be seen via the HMD. We found that (1) tactile stimuli were mislocalized towards the seen body (2) CCEs were modulated systematically during visual-somatosensory conflict when subjects viewed their body but not when they viewed a body-sized object, i.e. CCEs were larger during synchronous than during asynchronous stroking of the body and (3) these changes in the mapping of tactile stimuli were induced in the same experimental condition in which predictable changes in bodily self-consciousness occurred. CONCLUSIONS/SIGNIFICANCE: These data reveal that systematic alterations in the mapping of tactile stimuli occur in a full body illusion and thus establish CCE magnitude as an online performance proxy for subjective changes in global bodily self-consciousness
