Aims: The purpose of this study was to investigate the effects of a breast cancer screening educational program on women's knowledge and intention to seek breast cancer screening in Taiwan. Materials and Method: This study describes the knowledge and intention of breast cancer screening changes during the period pre and post group education. A pre-test and post-test were used in both the experimental and the control groups. A convenience sampling was used. Two structured questionnaires were used. Results: The mean knowledge of breast cancer screening scores (pre-test and post-test) of the experimental group participants were 12.6 and 14.0. Then the mean knowledge of breast cancer screening scores (pre-test and post-test) of the control group participants were 11.8 and 12.1. The mean intention of breast cancer screening scores (pre-test and post-test) of the experimental group participants were 11.4 and 13.5. And the mean intention of breast cancer screening scores (pre-test and post-test) of the control group participants were 11.6 and 12.4. An independent-t test was applied to examine the differences among the two groups, revealing that the average post-test knowledge score differ significantly between the two groups (t =4.18, p<.00); and the post-test intention also demonstrate a marked statistical difference (t = 2.07, p<.05). A paired-t test was applied to examine the differences of each group, revealing that the total average scores of the experimental group participants on the knowledge of breast cancer screening scale clearly differ statistically (t =-5.54, p<.00); and the pre-test and post-test intention testing also demonstrate a marked statistical difference (t =-7.70, p<.00). Conclusions: These findings are helpful in understanding the knowledge and intention of breast cancer screening changes during the period pre and post group education. It is expected that these results can offer a reference for clinical breast cancer prevention.

Motivation: Synthetic biology aims to develop the artificial gene networks with desirable behaviors using systematic method. These networks with desired behaviors could be constructed using diverse biological parts, which may limit the development to complex synthetic gene networks. Fortunately, some well-characterized promoter libraries for engineering gene networks are widely available. Thus, a synthetic gene network can be constructed by selecting adequate promoters from promoter libraries to achieve the desired behaviors. However, the present promoter libraries cannot be directly applied to engineer a synthetic gene network. In order to efficiently select adequate promoters from promoter libraries for a synthetic gene network, promoter libraries are needed to be redefined based on the dynamic gene regulation.Results: Based on four design specifications, a library-based search method is proposed to efficiently select the most adequate promoter set from the redefined promoter libraries by a genetic algorithm (GA) to achieve optimal reference tracking design. As the number and size of promoter libraries increase, the proposed method can play an important role in the systematic design of synthetic biology. © The Author 2011.

Cuttlefish seem to be able to distinguish between large and small numbers, at least when it comes to food. Tsang-I Yang and Chuan-Chin Chiao at National Tsing Hua University in Hsinchu, Taiwan, let pharaoh cuttlefish (Sepia pharaonis; pictured) in the lab choose between two chambers containing different numbers of shrimps to eat. The animals consistently selected the chamber with more shrimps, regardless of whether there was a large or small difference in prey numbers. The cuttlefish also opted for two shrimps that were smaller and easier to eat than one large shrimp. But if they were hungry, they took the bigger and trickier meal. This shows that cuttlefish have a number sense, and that their choice of prey is motivated by both hunger and the size of the potential reward, the authors say.

We report highly facet-dependent electrical properties of Cu2O nanocubes and octahedra and significant enhancement of gold nanocrystal cores to the electrical conductivity of Au-Cu2O core-shell octahedra. Cu 2O nanocubes and octahedra and Au-Cu2O coreshell cubes and octahedra were synthesized by following our reported facile procedures at room temperature. Two oxide-free tungsten probes attached to a nanomanipulator installed inside a scanning electron microscope made contacts to a single Cu2O nanocrystal for the I-V measurements. Pristine Cu2O octahedra bounded by {111} facets are 1100 times more conductive than pristine Cu2O cubes enclosed by {100} faces, which are barely conductive. Core-shell cubes are only slightly more conductive than pristine cubes. A 10 000-fold increase in conductivity over a cube has been recorded for an octahedron. Remarkably, core-shell octahedra are far more conductive than pristine octahedra. The same facet-dependent electrical behavior can still be observed on a single nanocrystal exposing both {111} and {100} facets. This new fundamental property may be observable in other semiconductor nanocrystals. We also have shown that both core-shell cubes and octahedra outperform pristine cubes and octahedra in the photodegradation of methyl orange. Efficient photoinduced charge separation is attributed to this enhanced photocatalytic activity. Interestingly, facet-selective etching occurred over the {100} corners of some octahedra and core-shell octahedra during photocatalysis. The successful preparation of Au-Cu2O core-shell heterostructures with precise shape control has offered opportunities to discover new and exciting physical and chemical properties of nanocrystals. © 2010 American Chemical Society.
