Perception du risque lié au tabagisme: données et interrogations [Smoking risk perception: facts and questions]

Based on general concepts relating to risk perception, the authors summarize in this article today's knowledge of smoking risk perception. A pluridisciplinary approach (general internal medicine, public health and anthropology) allows an improved understanding of its complexity, its utility in every day clinical practice and of the questions still pending around its use and evaluation in research projects.

Steady-state expression of self-regulated genes.

MOTIVATION: Regulatory gene networks contain generic modules such as feedback loops that are essential for the regulation of many biological functions. The study of the stochastic mechanisms of gene regulation is instrumental for the understanding of how cells maintain their expression at levels commensurate with their biological role, as well as to engineer gene expression switches of appropriate behavior. The lack of precise knowledge on the steady-state distribution of gene expression requires the use of Gillespie algorithms and Monte-Carlo approximations. METHODOLOGY: In this study, we provide new exact formulas and efficient numerical algorithms for computing/modeling the steady-state of a class of self-regulated genes, and we use it to model/compute the stochastic expression of a gene of interest in an engineered network introduced in mammalian cells. The behavior of the genetic network is then analyzed experimentally in living cells. RESULTS: Stochastic models often reveal counter-intuitive experimental behaviors, and we find that this genetic architecture displays a unimodal behavior in mammalian cells, which was unexpected given its known bimodal response in unicellular organisms. We provide a molecular rationale for this behavior, and we implement it in the mathematical picture to explain the experimental results obtained from this network.

Northern Ireland Registry of Deliberate Self-Harm Western area Annual Report 2010

This is the fourth report from the Northern Ireland Registry of Deliberate Self-Harm since its pilot stage in 2007. The NI Registry is part of the Northern Ireland Suicide Prevention Strategy "Protect Life - A Shared Vision?. The NI Registry is a collaboration with the National Registry of Deliberate Self-harm in the Republic of Ireland which has been operating since 2000.

The perception of touch and the ventral somatosensory pathway.

In humans, touching the skin is known to activate, among others, the contralateral primary somatosensory cortex on the postcentral gyrus together with the bilateral parietal operculum (i.e. the anatomical site of the secondary somatosensory cortex). But which brain regions beyond the postcentral gyrus specifically contribute to the perception of touch remains speculative. In this study we collected structural magnetic resonance imaging scans and neurological examination reports of patients with brain injuries or stroke in the left or right hemisphere, but not in the postcentral gyrus as the entry site of cortical somatosensory processing. Using voxel-based lesion-symptom mapping, we compared patients with impaired touch perception (i.e. hypoaesthesia) to patients without such touch impairments. Patients with hypoaesthesia as compared to control patients differed in one single brain cluster comprising the contralateral parietal operculum together with the anterior and posterior insular cortex, the putamen, as well as subcortical white matter connections reaching ventrally towards prefrontal structures. This finding confirms previous speculations on the 'ventral pathway of somatosensory perception' and causally links these brain structures to the perception of touch.

Asthma self-management action plan

This�self-management action plan allows each patient to record and manage the symptoms of�asthma.

NI Registry of Self-harm Annual Report 2012/13

The purpose of the registry is to improve understanding about self-harm and related behaviours in Northern Ireland. The information gathered will be used to monitor trends and patterns over time and, perhaps most importantly, will help shape the development of services and support to meet need. The information will also help provide trusts and the Department of Health, Social Services and Public Safety with a more accurate understanding of the impact of self-harm on Emergency Departments.

Media guidelines for reporting suicide and self-harm

These guidelines are for those in the media who have involvement with the reporting or portrayal of suicide and represent an important source of information to help ensure that the quality of reporting and portrayal on this important and sensitive topic is of a high standard.
