NF-kappaB transmits Eda A1/EdaR signalling to activate Shh and cyclin D1 expression, and controls post-initiation hair placode down growth.

A novel function of NF-kappaB in the development of most ectodermal appendages, including two types of murine pelage hair follicles, was detected in a mouse model with suppressed NF-kappaB activity (c(IkappaBalphaDeltaN)). However, the developmental processes regulated by NF-kappaB in hair follicles has remained unknown. Furthermore, the similarity between the phenotypes of c(IkappaBADeltaN) mice and mice deficient in Eda A1 (tabby) or its receptor EdaR (downless) raised the issue of whether in vivo NF-kappaB regulates or is regulated by these novel TNF family members. We now demonstrate that epidermal NF-kappaB activity is first observed in placodes of primary guard hair follicles at day E14.5, and that in vivo NF-kappaB signalling is activated downstream of Eda A1 and EdaR. Importantly, ectopic signals which activate NF-kappaB can also stimulate guard hair placode formation, suggesting a crucial role for NF-kappaB in placode development. In downless and c(IkappaBalphaDeltaN) mice, placodes start to develop, but rapidly abort in the absence of EdaR/NF-kappaB signalling. We show that NF-kappaB activation is essential for induction of Shh and cyclin D1 expression and subsequent placode down growth. However, cyclin D1 induction appears to be indirectly regulated by NF-kappaB, probably via Shh and Wnt. The strongly decreased number of hair follicles observed in c(IkappaBalphaDeltaN) mice compared with tabby mice, indicates that additional signals, such as TROY, must regulate NF-kappaB activity in specific hair follicle subtypes.

Transitory Economic Shocks and Civil Conflict

I examine whether civil conflict is triggered by transitory negative economic shocks. My approach follows Miguel, Satyanath, and Sergenti (2004) in using rainfall as an exogenous source of economic shocks in Sub-Saharan African countries. The main difference is that my empirical specifications take into account that rainfall shocks are transitory. Failure to do so may, for example, lead to the conclusion that civil conflict is more likely to break out following negative rainfall shocks when conflict is most probable following years with exceptionally high rainfall levels.

Quel âge post-séculier ? Religions, démocraties, sciences

Que signifient les discours actuels en faveur du « post-séculier » ? Et pourquoi faudrait-il en finir avec l'âge séculier ? Qui l'exige ou le demande ? Quels sont les événements qui le requièrent ? Ces dernières années, un débat sur la place de la religion dans les démocraties libérales s'est engagé dans le monde intellectuel. Si certains ont parlé d'un Âge séculier et d'autres d'une « société post-séculière », c'est parfois la dynamique même de sécularisation de l'espace public qui semble avoir été remise en cause. Plus profondément, ce sont les rapports entre religions, sciences et démocraties qui ont été questionnés. En faisant délibérément usage de ces termes au pluriel - pour indiquer qu'il existe différentes formes de religion, plusieurs genres de sciences et plusieurs conceptions de la démocratie - les contributions rassemblées dans ce volume entendent sonder ces rapports et cette pluralité. Le lecteur y trouvera la traduction française de plusieurs interventions de John Dewey sur l'anti-naturalisme et la religion, des contributions de pragmatistes contemporains et des enquêtes sur le rôle public de la foi ou sur la mise en cause de l'autorité épistémique des sciences, aussi bien aux États-Unis, qu'en Europe et en Afrique du nord.

Modelling the effect of minor orthopaedic day surgery on patient mood at the early post-operative period: a prospective population-based cohort study.

OBJECTIVE: The effect of minor orthopaedic day surgery (MiODS) on patient's mood. METHODS: A prospective population-based cohort study of 148 consecutive patients with age above 18 and less than 65, an American Society of Anaesthesiology (ASA) score of 1, and the requirement of general anaesthesia (GA) were included. The Medical Outcomes Study - Short Form 36 (SF-36), Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) were used pre- and post-operatively. RESULTS: The mean physical component score of SF-36 before surgery was 45.3 (SD=+/-10.1) and 8 weeks following surgery was 44.9 (SD=+/-11.04) [n=148, p=0.51, 95% CI=(-1.03 to 1.52)]. For the measurement of the changes in mood using BDI, BAI and SF-36, latent construct modelling was employed to increase validity. The covariance between mood pre- and post-operatively (cov=69.44) corresponded to a correlation coefficient, r=0.88 indicating that patients suffering a greater number of mood symptoms before surgery continue to have a greater number of symptoms following surgery. When the latent mood constructs were permitted to have different means the model fitted well with chi(2) (df=1)=0.86 for which p=0.77, thus the null hypothesis that MiODS has no effect on patient mood was rejected. CONCLUSIONS: MiODS affects patient mood which deteriorates at 8 weeks post-operatively regardless of the pre-operative patient mood state. More importantly patients suffering a greater number of mood symptoms before MiODS continue to have a greater number of symptoms following surgery.

Quality assurance of the EORTC 22043-30041 trial in post-operative radiotherapy in prostate cancer: Results of the Dummy Run procedure.

BACKGROUND AND PURPOSE: The EORTC 22043-30041 trial investigates the role of the addition of androgen suppression to post-operative radiotherapy in patients who have undergone radical prostatectomy. As part of the quality assurance of radiotherapy (QART) a Dummy Run (DR) procedure was performed. MATERIALS AND METHOD: The protocol included detailed and published delineation guidelines. Participating institutions digitally submitted radiotherapy treatment volumes and a treatment plan for a standard clinical case. Submissions were centrally reviewed using the VODCA software platform. RESULTS: Thirty-eight submissions from thirty-one institutions were reviewed. Six were accepted without comments. Twenty-three were accepted with comments on one or more items: target volume delineation (22), OAR delineation (23), planning and dosimetry (3) or treatment verification (1). Nine submissions were rejected requiring resubmission, seven for target volume delineation reasons alone. Intervention to highlight the importance of delineation guidelines was made prior to the entry of the first patient in the trial. After this, a lower percentage of resubmissions was required. CONCLUSIONS: The EORTC 22043-30041 Dummy Run highlights the need for timely and effective QART in clinical trials. The variation in target volume and OAR definition demonstrates that clinical guidelines and radiotherapy protocols are not a substitute for QART procedures. Early intervention in response to the Dummy Run improved protocol understanding.

Post-traumatic stimulus suppressible myoclonus of peripheral origin.

A patient is described who presented with myoclonus of the first dorsal interosseus muscle of the right foot. This myoclonus occurred 18 months after trauma of the cutaneous branch of the deep peroneal nerve on the dorsal aspect of the foot. Tactile stimulation in the dermatome of this nerve, or an anaesthetic block of the deep peroneal nerve stopped the myoclonus. The different innervation between the efferent motor activity responsible for the movements and the sensory afference suppressing it points firmly towards involvement of central connections. However, abolition of the movement by anaesthesia suggests the presence of a peripheral ectopic generator. This finding confirms that focal myoclonus can have its origin in the peripheral nervous system and may be modulated by sensory inputs.

Post-axial polydactyly type A2, overgrowth and autistic traits associated with a chromosome 13q31.3 microduplication encompassing miR-17-92 and GPC5.

Genomic rearrangements at chromosome 13q31.3q32.1 have been associated with digital anomalies, dysmorphic features, and variable degree of mental disability. Microdeletions leading to haploinsufficiency of miR17∼92, a cluster of micro RNA genes closely linked to GPC5 in both mouse and human genomes, has recently been associated with digital anomalies in the Feingold like syndrome. Here, we report on a boy with familial dominant post-axial polydactyly (PAP) type A, overgrowth, significant facial dysmorphisms and autistic traits who carries the smallest germline microduplication known so far in that region. The microduplication encompasses the whole miR17∼92 cluster and the first 5 exons of GPC5. This report supports the newly recognized role of miR17∼92 gene dosage in digital developmental anomalies, and suggests a possible role of GPC5 in growth regulation and in cognitive development.

Implementing the intermed in a post-acute care rehabilitation clinic for traumatic injuries: Obstacles and benefits

In 2003, the INTERMED, an instrument to assess biopsycho- social case complexity and to direct care, was introduced in daily clinical practice in the .Clinique romande de réadaptation suvaCare., a national rehabilitation hospital for traumatic injuries, located in the French speaking part of Switzerland. The introduction of the INTERMED was easy to realize and no major obstacles hampered its systematic implementation. Up to now, about 2,000 patients have been evaluated with the INTERMED and are followed for different outcomes. The INTERMED improved not only patients. assessment by including relevant psychosocial aspects of the clinical situation, it also favoured interdisciplinary communication, enhanced work satisfaction of the nursing staff and allowed early identification and adaptation of treatment for the injured patient showing a high degree of case complexity. Upon follow up, patients with a high degree of case-complexity showed a less favourable outcome, i.e. more health care utilization and lower rates of return to work. In conclusion, the systematic implementation of the INTERMED enabled the reorganization of medical rehabilitation, anchored it in a bio-psycho-social framework, improving interdisciplinary communication and collaboration and ameliorated treatment outcome.
