We succeeded in producing mature seed from a line of Brassica rapa ssp. pekinensis that had been hybridized with Raphanus sativus var. major. Our focus was on dominance of B. rapa ssp. pekinensis;radish (R. sativus var. major) had no influence. Marker tests for similarity showed that the original CR291M-64 x HwiM-2 hybrid was an inbred CR291M-64, rather than a genuine cross;this appears to have resulted from weak self-incompatibility in this strain. The plants from the mature seed bloomed with reddish flowers differently shown up to present. The intergeneric hybrid between Brassica inbred and Raphanus hybrid was very weak in strength compared to the Brassica inbred which was self-pollinated even though the cause of the weak was not identified. The hybrids between Brassica hybrid, dominant and elite recessive, and Raphanus can be developed in large quantities using mature hybrid seed without resorting to ovule culture techniques.

陈嘉庚的一生事迹,不但对中国与南洋发挥了重大的双向影响,也体现了中国与世界在经济和社会方面的密切接轨,促进了华人族群传统与现代文明的跨境整合。一方面,他在新加坡发迹起家,成为东南亚经济与商业的翘楚,担任华人社会各类团体的领袖。另一方面,他对中国深度关怀,积极改进社会,参与政治活动。透过现代性与文化遗产两个视角,重新语境化、概念化陈嘉庚作为历史人物的典型意义,以探讨他生平所揭示的现代意识以及所衍生的文化遗产。陈嘉庚一生积极参与中国与南洋两个场域的历史进程,并推动现代经济与教育的发展。在民族思想与国族概念的觉醒浪潮下,陈嘉庚阐释了华人族群的身份认同。陈嘉庚的文化遗产在中国与新加坡得到延续,这表现为陈嘉庚科学奖基金会和陈嘉庚基金的设立,以及一些纪念性的印记与地标。

Apoptosis or programmed cell death plays an essential role in chemotherapy-induced tumor cell killing, and inducers of apoptosis are commonly used in cancer therapy. Treatment with Zelkova serrata extracts was performed in human gingival fibroblast （HGF）, mouth epidermoid carcinoma cell （KB）, lower gingival squamous cancer cell （YD38） and tongue mucoepidermoid carcinoma cells （YD15）. We observed that extract prepared from Zelkova serrata twig selectively inhibited proliferation of various oral cancer cells, but not normal gingival fibroblasts, in a dose-dependent manner. Caspase-8-mediated apoptosis was induced by treatment with the extract only in mouth epidermoid carcinoma and not in other types of cancer cells, including lower gingival squamous cell carcinoma. The selective apoptotic effect of Zelkova serrata twig extract in mouth epidermoid carcinoma was dependent on normal p53 status. Apoptosis was not remarkably induced by treatment with the extract in either lower gingival squamous or tongue mucoepidermoid carcinoma cells, both of which contain abnormalities of p53. Upon treatment with Zelkova serrata twig extract, mouth epidermoid carcinoma cells accumulated in S phase by activation of p21. These data indicate that Zelkova serrata twig extract exerted a cancer type-specific, p53-dependent apoptotic effect and disturbed the cell cycle, which suggests that herbal medicine could be a treatment for specific types of cancers.

In this study, leaf-like one-dimensional InAs nanostructures were grown by the metal-organic chemical vapor deposition method. Detailed structural charac- terization suggests that the nanoleaves contain relatively low-energy {122} or {133} mirror twins acting as their midribs and narrow sections connecting the nanoleaves and their underlying bases as petioles. Importantly, the mirror twins lead to identical lateral growth of the twinned structures in terms of crystallography and polarity, which is essential for the formation of lateral symmetrical nanoleaves. It has been found that the formation of nanoleaves is driven by catalyst energy minimization. This study provides a biomimic of leaf found in nature by fabricating a semiconductor nanoleaf.
