The CYP1A1 hyperinducibility phenotype occurring in some 10% of the human population corresponds to a higher risk of developing lung cancer. This study was undertaken to assess whether the inducibility factor, generally evaluated on mitogen-activated lymphocytes after PAH induction, represents correctly the lung situation. Optimal experimental conditions were determined for evaluating, on both lymphocytes and lung tissue explants, the inducibility factor, defined as the ratio of EROD activity (CYP1A1-specific) to cytochrome c reductase activity (unaffected by PAH induction). Paired results for lymphocytes and lung tissue samples from 10 lung cancer patients were compared. A good correlation was observed between lymphocyte and lung tissue inducibilities (R = 0.809; p = 0.005). In conclusion, mitogen-activated lymphocyte inducibility is indicative of lung tissue inducibility and constitutes a good marker for evaluating individual PAH inducibilities. [less ▲]

Cold acclimation induces an adaptative increase in respiration in brown adipose tissue (BAT). A comparative analysis by two-dimensional differential in-gel electrophoresis of mitochondrial protein patterns found in rat control and cold-acclimated BAT was performed. A total of 58 proteins exhibiting significant differences in their abundance was unambiguously identified. Proteins implicated in the major catabolic pathways were up-regulated as were ATP synthase and mitofilin. Moreover, these results support the fact that adipocytes can balance their ATP synthesis and their heat production linked to UCP1-sustained uncoupling. [less ▲]

OBJECTIVE: The study of the mitral valve apparatus and its modifications during functional mitral regurgitation (FMR) is better revealed by 3-dimensional (3D) transesophageal echocardiography (TOE). To plan mitral valve repair by annuloplasty and papillary muscle (PPM) relocation, we proposed a valve repair procedure oriented by the new main features obtained by real-time 3D TOE reconstruction of the mitral valve apparatus. METHODS: Since January 2008, 25 patients with severe FMR before mitral valve repair were examined. Mean coaptation depth and mean tenting area were 1.3 +/- 0.2 cm and 3.2 +/- 0.5 cm(2), respectively. Intraoperative 2D and 3D TOE were performed, followed by a 3D offline reconstruction of the mitral valve apparatus. A schematic mitral valve apparatus model was obtained. A geometric model like a truncated cone was traced in according to the preoperative measurements. The size of the prosthetic ring was selected preoperatively according to the anterior leaflet surface. The expected truncated cone after annuloplasty was retraced. A conventional normal coaptation depth about 0.6 cm was used to detect the new position of the PPM tips. RESULTS: Offline reconstruction of the mitral valve apparatus and respective truncated cone were feasible in all patients. The expected position of the PPM tips desirable to reach a normal tenting area with a coaptation depth 0.6 cm or less was obtained in all patients. After surgery, all parameters were calculated and no statistically significant difference was found compared with the expected data. CONCLUSIONS: PPM relocation plus ring annuloplasty reduce mitral valve tenting and may improve mitral valve repair results for patients with severe FMR. This technique may be easily and precisely guided by preoperative offline 3D echocardiographic mitral valve reconstruction. [less ▲]

A cardiovascular and circulatory system (CVS) model has been validated in silico, and in several animal model studies. It accounts for valve dynamics by means of Heaviside function to simulate “open on pressure, close on flow” law. Thus, it does not consider the real time scale of the valve aperture and thus doesn’t fully capture valve dysfunction. This work describes a new coupled model of the cardiovascular system that accounts for progressive mitral valve aperture. Simulations show good correlation with physiologically expected results for healthy or diseased valves. The large number of valve model parameters indicates a need for emerging, lighter and minimal mitral valve models that are readily identifiable to achieve full benefit in real-time use. These results suggest a further use of this model to track, diagnose and control valves pathologies. [less ▲]

A cardiovascular and circulatory system (CVS) model has been validated in silico, and in several animal model studies. It accounts for valve dynamics by means of Heaviside function to simulate “open on pressure, close on flow” law. Thus, it does not consider the real time scale of the valve aperture and thus doesn’t fully capture valve dysfunction. This research couples the CVS model with a model describing the progressive aperture of the mitral valve. [less ▲]

The present paper looks into the problem of optimising the loading of boxes into containers. The goal is to minimise the unused volume. This type of problem belongs to the family of Multiple Bin Size Bin Packing Problems. The approach includes an extensive set of constraints encountered in real-world applications in the three-dimensional case: the stability, the fragility of the items, the weight distribution and the possibility to rotate the boxes. It also includes the specific situation in which containers are truncated parallelepipeds. This is typical in the field of air transportation. While most papers on cutting and packing problems describe ad-hoc procedures, this paper proposes a mixed integer linear program. The validity of this model is tested on small instances. [less ▲]

Both products were characterized by H-1, C-13, and P-33 NMR spectroscopy, and the molecular structure of [RuCl2(isobutylphobane)(SIMes)(3-phenyl-1-indenylidene)] was determined by X-ray diffraction analysis. A close inspection of the packing structure revealed the presence of different types of intra- and intermolecular interactions that enhanced the global stability of the crystals, while low temperature NMR experiments showed the existence of two distinct rotational isomers due to the unsymmetrical nature of the phobane ligand The catalytic activity of both compounds was assessed in olefin metathesis using [less ▲]
