Eleven samples of the traditional date product " Btana" prepared by direct (DBM) and indirect method (UBM) were analysed to characterize their bacterial diversity. A total of 42 representative isolates have been chosen for molecular identification. 16S rRNA gene sequencing revealed the presence of 20 species within 30.9% belonged to the genus Bacillus, 28.6% of the Staphylococcus, and Enterococcus genus. Within the minority represented species, two isolates were identified as Paenibacillus (isolated from UBM exclusively), Streptococci salivarius, Lactobacillus sakei and Klebsiella pneumoniae. Preliminary results indicate that IBM is more selective for spore former bacilli contrary to DBM that show more diversity in the bacterial flora with a prevalence of Enterococcus. API ZYM test showed that the bacilli species have a weak hydrolase activity. [less ▲]

Resting-state functional connectivity analysis has become a widely used method for the investigation of human brain connectivity and pathology. The measurement of neuronal activity by functional MRI, however, is impeded by various nuisance signals that reduce the stability of functional connectivity. Several methods exist to address this predicament, but little consensus has yet been reached on the most appropriate approach. Given the crucial importance of reliability for the development of clinical applications, we here investigated the effect of various confound removal approaches on the test–retest reliability of functional connectivity estimates in two previously defined functional brain networks. Our results showed that gray matter masking improved the reliability of connectivity estimates, whereas denoising based on principal components analysis reduced it. We additionally observed that refraining from using any correction for global signals provided the best test–retest reliability, but failed to reproduce anti-correlations between what have been previously described as antagonistic networks. This suggests that improved reliability can come at the expense of potentially poorer biological validity. Consistent with this, we observed that reliability was proportional to the retained variance, which presumably included structured noise, such as reliable nuisance signals (for instance, noise induced by cardiac processes). We conclude that compromises are necessary between maximizing test–retest reliability and removing variance that may be attributable to non-neuronal sources. [less ▲]

Familial pituitary adenomas accounts for approximately 5-8 % of all pituitary adenomas. Besides the adenomas occurring as part of syndromic entities that bring together several endocrine or other systems disorders, 2-3% of the familial pituitary adenomas fit into the familial isolated pituitary adenomas (FIPA) syndrome. 20% of FIPA syndromes have shown mutations in the AIP gene and have distinct clinical characteristics. Recent findings have isolated a new non-AIP FIPA syndrome called X-LAG, resulting from duplication in GPR-101 gene. These new advances in the field of pituitary disease are opening up a new challenging domain to both clinician and researcher. This review will focus on these last findings and their contribution to the diagnosis and the management of familial pituitary adenomas. [less ▲]

Purpose: This paper describes the theoretical background and main hypotheses at the basis of SAFIR®, a nonlinear finite element software for modeling structures in fire. The paper also explains how to use the software at its full extent. The discussed numerical modeling principles can be applied with other similar software. Approach: Following a general overview of the organization of the software, the thermal analysis part is explained, with the basic equations and the different possibilities to apply thermal boundary conditions (compartment fire, localized fire, etc.). Next, the mechanical analysis part is detailed, including the time integration procedures and the different types of finite elements: beam, truss, shell, spring and solid. Finally, the material laws are described. The software capabilities and limitations are discussed throughout the paper. Findings: By accommodating multiple types of finite elements and materials, by allowing the user to consider virtually any section type and to input the fire attack in multiple forms, the software SAFIR® is a comprehensive tool for investigating the behavior of structures in the fire situation. Meanwhile, being developed exclusively for its well-defined field of application, it remains relatively easy to use. Value: The paper will improve the knowledge of readers (researchers, designers and authorities) about numerical modeling used in structural fire engineering in general and the capabilities of a particular software largely used in the fire engineering community.

BACKGROUND: We provide a clinical and analytical evaluation of the reformulated version of the Abbott Architect 25-hydroxyvitamin D assay. We compared this assay with three commercial automated immunoassays and against a VDSP-traceable liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) in six different populations. We also supplemented 40 healthy volunteers with either 600,000 IU of vitamin D2 or 100,000 of vitamin D3 to evaluate the performance of the immunoassays vs. the LC-MS/MS. METHODS: Precision and limit of quantification were assessed, 25(OH)D2 and C3-epimer recovery were calculated. Two hundred and forty samples obtained in healthy Caucasians and Africans, osteoporotic, hemodialyzed and intensive care patients and 3rd trimester pregnant women were analyzed by all methods. Correlation was studied using Passing-Bablok and Bland-Altman analysis. Concordance correlation coefficient (CCC) was calculated to evaluate agreement between immunoassays and LC-MS/MS. We verified if patients were homogeneously classified with the immunoassays when they took vitamin D2 or vitamin D3 after 1, 7 and 28 days. RESULTS: We observed excellent analytical features and showed a very good correlation to the LC-MS/MS results in the overall population. Compared to the other immunoassays, concordance of the new Abbott assay with the LC-MS/MS was at least similar, and often better in diseased populations. Althought the cross-reactivity with 25(OH)D2 was not of 100%, there was no significant difference in the classifications of the patients, either supplemented with D2 or D3 or after 7 or 28 days. CONCLUSIONS: This modified version of the Abbott Architect assay is clearly improved compared to the previous one and presents a better agreement with the LC-MS/MS. [less ▲]

L’utilisation de la Blattmaske dans les décors pariétaux peints se fait selon diverses modalités. Pour en comprendre pleinement le sens, il convient de considérer le motif dans son contexte ornemental et architectural. Il s’agit tout d’abord de préciser le mode d’insertion des « têtes végétalisées » dans le reste de la décoration de la paroi. Car s’il est vrai qu’elles peuvent faire l’objet d’un jeu formel, elles ne doivent pas pour autant être considérées comme de purs éléments décoratifs. La mise en série dans des bandes « ornementales », l’isolement dans un cadre, ou encore le positionnement stratégique à un endroit clef d’une composition, accordent en effet au motif différents niveaux de lecture. L’analyse conjointe du décor ambiant permet par ailleurs de préciser davantage l’interprétation de l’image. Les Blattmasken se voient effectivement associées à différents motifs, parmi lesquels les êtres hybrides, ou encore les scènes marines ou dionysiaques. Enfin, il convient de préciser le contexte architectural dans lequel le motif est employé, la portée du message véhiculé par le programme décoratif dépendant de la fonction de la pièce et du bâtiment.

Well-validated reference values are necessary for a correct interpretation of a serum PTH concentration. Establishing PTH reference values needs recruiting a large reference population. Exclusion criteria for this population can be defined as any situation possibly inducing an increase or a decrease in PTH concentration. As recommended in the recent guidelines on the diagnosis and management of asymptomatic primary hyperparathyroidism, PTH reference values should be established in vitamin D-replete subjects with a normal renal function with possible stratification according to various factors such as age, gender, menopausal status, body mass index, and race. A consensus about analytical/pre-analytical aspects of PTH measurement is also needed with special emphasis on the nature of the sample (plasma or serum), the time and the fasting/non-fasting status of the blood sample. Our opinion is that blood sample for PTH measurement should be obtained in the morning after an overnight fast. Furthermore, despite longer stability of the PTH molecule in EDTA plasma, we prefer serum as it allows to measure calcium, a prerequisite for a correct interpretation of a PTH concentration, on the same sample. Once a consensus is reached, we believe an important international multicentre work should be performed to recruit a very extensive reference population of apparently healthy vitamin D-replete subjects with a normal renal function in order to establish the PTH normative data. Due to the huge inter-method variability in PTH measurement, a sufficient quantity of blood sample should be obtained to allow measurement with as many PTH kits as possible. [less ▲]

Architects express themselves graphically in order to communicate ideas both to clients and to themselves. In practice, they rely on a variety of representations such as free-hand drawings, 3D computer rendered images, and photomontages to convey their design intent. Research to date has demonstrated differences and commonalities in the ways in which expert designers and laymen perceive visual understanding. It is still unclear how architects themselves use different types of representations to express different intentions, and how accurately their expected audience perceives those intentions. The purpose of this research is to investigate how laymen interpret the initial design intent of an architect’s design, and what role different forms of representations play in this process of understanding a design. This paper describes a five-step process for developing a survey that was used to gather data from 686 laymen respondents. It was found that certain types of simpler representations presented in specific contexts are unexpectedly found to be a more efficient way to faithfully transmit an architectural intent. [less ▲]

Parmi les nombreux types de scène qui ornent les pinakes de Locres (Italie du Sud, Calabre), il en est un qui a particulièrement intrigué les commentateurs. Il s’agit du type 3/6, qui présente une scène de sacrifice : devant un temple à l’intérieur duquel se trouvent deux statues divines, l’une féminine et l’autre masculine, un couple accomplit une libation sur un autel, sur lequel brûle une part de l’animal sacrificiel. Cette scène, qui est l’une des plus complexes du point de vue de la composition, est très particulière et isolée au sein du corpus des pinakes locriens, et ce pour plusieurs raisons. Le détail qui retiendra plus spécialement notre attention est celui de la scène figurée sur l’autel, qui est toujours décrite comme une scène érotique entre un satyre et un cervidé, et qui a donné lieu à une série d’interprétations diverses. Ce jeu d’image dans l’image – et plus spécifiquement d’autel porteur d’une image – est fréquent dans l’imagerie grecque, et se retrouve aussi sur d’autres pinakes. Mais la présence du satyre est tout-à-fait particulière et la portée de cette scène difficile à appréhender au sein de ce corpus en lien avec la sphère féminine et le rituel nuptial. On verra toutefois que, s’il est vrai qu’elle n’a visiblement pas eu beaucoup de succès (seuls cinq exemplaires sont attestés sur les 1200 qui composent le corpus), cette image n’est peut-être pas si étrange que cela, et ce qui apparaît au premier regard comme une scène "grossière" pourrait bien être en fait une ingénieuse métaphore, qui a entièrement sa place sur un pinax locrien.
