« Le calvaire du Steinach-Film » (1922-23). Représentations du médecin dans le film de recherche et d'enseignement médical
Authors: Bonah Christian , Zimmer Alexis 
Published: August 2010

Résumé Produit par la Ufa en 1922-23, le Steinach-Film présente l’œuvre théorique et pratique du physiologiste autrichien Eugen Steinach (1861-1944), consacrée aux connaissances sur la différentiation sexuelle et le rajeunissement. Il s’agit d’un film « documentaire » d’enseignement et de recherche qui décrit un « monde de sciences » où l’on dispense un savoir médical. Mais il s’agit aussi d’emblée d’un espace d’(auto)projection du corps médical. À partir d’une longue tradition de « films de faits » où un médecin présente et cautionne des données factuelles, la contribution interroge comment des films de non-fiction choisissent de représenter le médecin au-delà de son rôle d’auteur et d’autorité d’un discours scientifique. À partir des données de la censure du film, elle s’attache aussi à sa réception. La représentation du médecin dans le film muet d’enseignement et de recherche relève d’un double paradoxe. La caméra construit auprès du public de nouveaux référents pour connaître le monde « réel », en même temps qu’elle instaure certains portraits du médecin. Cette double construction se fait dans un espace de tension mettant à jour des intérêts contradictoires entre le chercheur et le réalisateur et plus largement entre la profession médicale et le public que la contribution tente d’analyser et de comprendre à partir d’une étude de cas exemplaire, celle du « calvaire du Steinach-Film ».
Distribution and population dynamics of the edible bivalve species <i>Meretrix casta</i> (Chemnitz) in the Dutch canal of Sri Lanka
Authors: Jayawickrema EM , Wijeyaratne MJS 
Published: August 2010

Meretrix casta is a commercially important clam species in Dutch canal, a slow flowing brackish water body in the western coastal region of Sri Lanka. Its abundance at five sampling sites along a 50 km stretch of the canal, which ranged from 60 individuals m-2 to 950 individuals m-2, significantly increased with increasing sand, silt and organic matter content of the bottom sediments. Abundance was negatively correlated with the clay content of the sediments. No significant correlation was recorded between the abundance and environmental parameters such as temperature, salinity, pH and chlorophyll-a content of water. However, abundance was low at the sampling sites with extreme values of salinity (40 ppt) and pH (8.5).Asymptotic length of the clams ranged from 34 mm to 43.1 mm and the growth coefficient ranged from 0.84 year-1 to 1.44 year-1. The ranges for total mortality, natural mortality and fishing mortality coefficients were 2.34-3.08 year-1, 0.84-1.44 year-1 and 1.16-2.24 year-1 respectively. The highest asymptotic length was recorded at the site where the abundance was the highest. The lowest natural mortality and the highest fishing mortality were also recorded at this site. Environmental parameters at this site were moderate and never reached extreme values indicating optimum conditions for growth and survival. The mean size at first capture (L50) ranged from 8.3 mm to 24.5 mm while the optimum value for L50 ranged from 13.6 mm to 23.3 mm. At four sampling sites, present L50 was smaller than the optimum value indicating the exploitation of small individuals. Exploitation rates at two sampling sites were higher than the optimum level indicating over-exploitation of the resource at some places along the canal. DOI: 10.4038/sljas.v14i0.2191Sri Lanka J.

Published: August 2010

AbstractObjectiveTo compare the strength of the hip musculature in people with symptomatic medial knee osteoarthritis (OA) with asymptomatic controls.MethodsEighty‐nine people with knee OA and 23 controls age >50 years were recruited from the community. The maximal isometric strength (torque relative to body mass) of the hip abductors, adductors, flexors, extensors, and internal and external rotators was evaluated using hand‐held dynamometry or a customized force transducer apparatus. Univariate linear models with age and sex included as covariates were used to compare muscle strength between groups.ResultsIn people with knee OA, significant strength deficits were evident for all hip muscle groups evaluated (P < 0.05). Compared with controls, strength deficits ranged from 16% (hip extensors) to 27% (hip external rotators) after accounting for differences in sex and age between groups.ConclusionPeople with knee OA demonstrate significant weakness of the hip musculature compared with asymptomatic controls. It is not clear if hip muscle weakness precedes the onset of knee OA or occurs as a consequence of disease. Findings from this study support the inclusion of hip strengthening exercises in rehabilitation programs.
Voxel‐based morphometry depicts central compensation after vestibular neuritis
Authors: zu Eulenburg Peter , Stoeter Peter , Dieterich Marianne 
Published: August 2010

AbstractObjectivePatients who have had vestibular neuritis (VN) show a remarkable clinical improvement especially in gait and posture >6 months after disease onset.MethodsVoxel‐based morphometry was used to detect the VN‐induced changes in gray and white matter by means of structural magnetic resonance imaging. Twenty‐two patients were compared an average 2.5 years after onset of VN to a healthy sex‐and age‐matched control group.ResultsOur analysis revealed that all patients had signal intensity increases for gray matter in the medial vestibular nuclei and the right gracile nucleus and for white matter in the area of the pontine commissural vestibular fibers. A relative atrophy was observed in the left posterior hippocampus and the right superior temporal gyrus. Patients with a residual canal paresis also showed an increase of gray matter in middle temporal (MT)/V5 bilaterally.InterpretationThese findings indicate that the processes of central compensation after VN seem to occur in 3 different sensory systems. First of all, the vestibular system itself showed a white matter increase in the commissural fibers as a direct consequence of an increased internuclei vestibular crosstalk of the medial vestibular nuclei. Second, to regain postural stability, there was a shift to the somatosensory system due to an elevated processing of proprioceptive information in the right gracile nucleus. Third, there was a bilateral increase in the area of MT/V5 in VN patients with a residual peripheral vestibular hypofunction. This seems to be the result of an increased importance of visual motion processing. ANN NEUROL 2010;68:241–249
A review of paroxysmal sympathetic hyperactivity after acquired brain injury
Authors: Perkes Iain , Baguley Ian J. , Nott Melissa T. , Menon David K. 
Published: August 2010

AbstractSevere excessive autonomic overactivity occurs in a subgroup of people surviving acquired brain injury, the majority of whom show paroxysmal sympathetic and motor overactivity. Delayed recognition of paroxysmal sympathetic hyperactivity (PSH) after brain injury may increase morbidity and long‐term disability. Despite its significant clinical impact, the scientific literature on this syndrome is confusing; there is no consensus on nomenclature, etiological information for diagnoses preceding the condition is poorly understood, and the evidence base underpinning our knowledge of the pathophysiology and management strategies is largely anecdotal. This systematic literature review identified 2 separate categories of paroxysmal autonomic overactivity, 1 characterized by relatively pure sympathetic overactivity and another group of disorders with mixed parasympathetic/sympathetic features. The PSH group comprised 349 reported cases, with 79.4% resulting from traumatic brain injury (TBI), 9.7% from hypoxia, and 5.4% from cerebrovascular accident. Although TBI is the dominant causative etiology, there was some suggestion that the true incidence of the condition is highest following cerebral hypoxia. In total, 31 different terms were identified for the condition. Although the most common term in the literature was dysautonomia, the consistency of sympathetic clinical features suggests that a more specific term should be used. The findings of this review suggest that PSH be adopted as a more clinically relevant and appropriate term. The review highlights major problems regarding conceptual definitions, diagnostic criteria, and nomenclature. Consensus on these issues is recommended as an essential basis for further research in the area. ANN NEUROL 2010;68:126–135
Human prion strain selection in transgenic mice

Published: August 2010

AbstractObjective:Transgenic (Tg) mice expressing chimeras of mouse and human prion proteins (PrPs) have shorter incubation periods for Creutzfeldt‐Jakob disease (CJD) prions than mice expressing full‐length human PrP. Increasing the sequence similarity of the chimeric PrP to mouse PrP, by reverting human residues to mouse, resulted in a Tg line, denoted Tg22372, which was susceptible to sporadic (s) CJD prions in ∼110 days.Methods:Mice expressing chimeric mouse/human PrP transgenes were produced. The mice were inoculated intracerebrally with extracts prepared from the brains of patients who died of CJD. Onset of neurological dysfunction marked the end of the incubation time. After sacrifice of the Tg mice, their brains were analyzed for PrPSc and neuropathological changes.Results:Reversion of 1 additional residue (M111V) resulted in a new Tg line, termed Tg1014, susceptible to sCJD prions in ∼75 days. Tg1014 mice also have shorter incubation periods for variant (v) CJD prions, providing a more tractable model for studying this prion strain. Transmission of vCJD prions to Tg1014 mice resulted in 2 different strains, determined by neuropathology and biochemical analysis, which correlated with the length of the incubation time. One strain had the biochemical, neuropathological, and transmission characteristics, including longer incubation times, of the inoculated vCJD strain; the second strain produced a phenotype resembling that of sCJD prions including relatively shorter incubation periods. Mice with intermediate incubation periods for vCJD prions had a mixture of the 2 strains. Both strains were serially transmitted in Tg1014 mice, which led to further reduction in incubation periods. Conversion of vCJD‐like to sCJD‐like strains was favored in Tg1014 mice more than in the Tg22372 line. The single amino acid difference therefore appears to offer selective pressure for propagation of the sCJD‐like strain.Interpretation:These 2 Tg mouse lines provide relatively rapid models to study human prion diseases as well as the evolution of human prion strains.

Scientific data repositories on the Web: An initial survey
Authors: Marcial Laura Haak , Hemminger Bradley M. 
Published: August 2010

AbstractScience Data Repositories (SDRs) have been recognized as both critical to science, and undergoing a fundamental change. A websample study was conducted of 100 SDRs. Information on the websites and from administrators of the SDRs was reviewed to determine salient characteristics of the SDRs, which were used to classify SDRs into groups using a combination of cluster analysis and logistic regression. Characteristics of the SDRs were explored for their role in determining groupings and for their relationship to the success of SDRs. Four of these characteristics were identified as important for further investigation: whether the SDR was supported with grants and contracts, whether support comes from multiple sponsors, what the holding size of the SDR is and whether a preservation policy exists for the SDR. An inferential framework for understanding SDR composition, guided by observations, characteristic collection and refinement and subsequent analysis on elements of group membership, is discussed. The development of SDRs is further examined from a business standpoint, and in comparison to its most similar form, institutional repositories. Because this work identifies important characteristics of SDRs and which characteristics potentially impact the sustainability and success of SDRs, it is expected to be helpful to SDRs.
Integrating genetic and toxicogenomic information for determining underlying susceptibility to developmental disorders
Authors: Robinson Joshua F. , Port Jesse A. , Yu Xiaozhong , Faustman Elaine M. 
Published: August 2010

AbstractTo understand the complex etiology of developmental disorders, an understanding of both genetic and environmental risk factors is needed. Human and rodent genetic studies have identified a multitude of gene candidates for specific developmental disorders such as neural tube defects (NTDs). With the emergence of toxicogenomic‐based assessments, scientists now also have the ability to compare and understand the expression of thousands of genes simultaneously across strain, time, and exposure in developmental models. Using a systems‐based approach in which we are able to evaluate information from various parts and levels of the developing organism, we propose a framework for integrating genetic information with toxicogenomic‐based studies to better understand gene‐environmental interactions critical for developmental disorders. This approach has allowed us to characterize candidate genes in the context of variables critical for determining susceptibility such as strain, time, and exposure. Using a combination of toxicogenomic studies and complementary bioinformatic tools, we characterize NTD candidate genes during normal development by function (gene ontology), linked phenotype (disease outcome), location, and expression (temporally and strain‐dependent). In addition, we show how environmental exposures (cadmium, methylmercury) can influence expression of these genes in a strain‐dependent manner. Using NTDs as an example of developmental disorder, we show how simple integration of genetic information from previous studies into the standard microarray design can enhance analysis of gene‐environment interactions to better define environmental exposure‐disease pathways in sensitive and resistant mouse strains.
