＜正＞ With the exception of tobacco consumption, diet is probably themost important factor in the etiology of human cancer, responsiblefor around one third of all cases. Despite strenuous attempts in i-dentification, no single causal factor stands out. However, car-cinogens may be introduced through preservation methods （N-ni-troso compounds）, high temperature cooking （heterocyclic aminesand polycyclic aromatic hydrocarbons） and spoilage （mycotoxins）.

New plants of Gnetales from Early Cretaceous of China, and its bearing on the early evolution of Ephedraceae and Welwitschiaceae in Gnetales

引用

科学通报 2013年第S1期58卷 200-209页

作者： LIU HaiMing ferguson David K. LI ChengSen WANG YuFei Beijing Museum of Natural History Department of Paleontology University of Vienna Institute of Botany Chinese Academy of Sciences

The Gnetales are a higher group of Gymnosperms, but our current knowledge of the morphology of the early Gnetales is lacking. Most known specimens are fragmentary, which makes it difficult to elucidate the geological history and the early diversity and evolution of the group. New well-preserved specimens have been discovered in Liaoning, north China, and a detailed morphological study was carried out. The material belongs to three new genera: Spinobractea lanceoleta gen. et sp. nov., Latibractea divisa gen. et sp. nov. and Constrobilus ovata gen. et sp. nov. The record of the Ephedraceae can be traced back to the Jurassic. The Ephedraceae were quite successful in the Cretaceous, and the plant types and the environment that they inhabited shown that the Cretaceous plants were much more varied than their living relatives. However, some types became extinct, and some features were lost. The record of the Welwitschiaceae can be traced back to the Triassic. Features of the leaf venation and the seeds are the primary features used for recognition of this family in both living and fossil plants. These features are so conservative that they have shown almost no major changes since the Triassic.

Three-dimensional mapping and comparative analysis of the distal human corpus cavernosum and the inflatable penile prosthesis

Asian Journal of Andrology 2013年第4期15卷 567-570,I0012页

作者： Tariq S Hakky Daniel ferguson Philippe E Spiess Paul Bradley Tom FLue rafael E Carrion Department of Urology University of South Florida Tampa General Circle Tampa FL 33602 USA 23D3Solutions Burnaby BCV5J 5M8 Canada and Department of Urology University of Southern California San Francisco 400 Parnassus Ave San Francisco CA 94143 USA

The intricate anatomy of the corpus cavernosum in both the flaccid and tumescent state has not been fully elucidated. We report our experience using a three-dimensional （3D） scanner to reconstruct cadaveric casts and compare them with 3D images of two prototypes of penile prosthesis. Two different models of the Titan Coloplast inflatable penile prosthesis were analyzed using a 3D scanner. The first was the standard model and the second was a newer model with a rounder silicone tip. Two cadaveric phalluses were harvested using Smooth-Cast 300Q polyurethane molding. The molds were excised and scanned along side the penile prosthesis. 3D scans were completed and analyzed using Leios Mesh software, and GOM Inspect software. The 3D scans demonstrated the mean human corporal radii 2 mm from the distal tip to be 36.51 mm （36.01-37.0 mm）, which is an obtuse angle. The standard Titan penile prosthesis spherical radius at the same level was 202.52 mm, while the new silicone tip prosthesis had a radius of 139.33 mm. 3D mapping further demonstrated the trajectory of the cavernosa appeared curvilinear and the distal ends appeared blunt. The use of cadaveric cavernosal molds in combination with the 3D scanner allowed us to accurately image the corpus cavernosum for the first time. Our findings suggest that anatomically accurate corporal tips appear to be relatively blunt and that the new Titan silicone tip penile prosthesis more closely resembles the human corporal tip.
