We investigate superdense coding in the case of non-symmetric Hilbert spaces of the sender’s and the receiver’s particles sharing the multipartite maximally quantum channel. We also consider that a symmetric quantum channel is transformed into a non-symmetric one. As a result, the efficiency of information transmission is successfully increased.

Background: The study aimed to describe the age distribution of breast cancer diagnosis among Chinese females for comparison with the United States and the European Union, and provide evidence for the screening target population in China. Materials and Methods: Median age was estimated from hospital databases from 7 tertiary hospitals in China. Population-based data in China, United States and European Union was extracted from the National Central Cancer Registry, SEER program and GLOBOCAN 2008, respectively. Age-standardized distribution of breast cancer at diagnosis in the 3 areas was estimated based on the World Standard Population 2000. Results: The median age of breast cancer at diagnosis was around 50 in China, nearly 10 years earlier than United States and European Union. The diagnosis age in China did not vary between subgroups of calendar year, region and pathological characteristics. With adjustment for population structure, median age of breast cancer at diagnosis was 50~54 in China, but 55~59 in United States and European Union. Conclusions: The median diagnosis age of female breast cancer is much earlier in China than in the United States and the European Union pointing to racial differences in genetics and lifestyle. Screening programs should start at an earlier age for Chinese women and age disparities between Chinese and Western women warrant further studies.

Leaf material explants of Pulsatilla tongkangensis Y. N. Lee & T. C. Lee were used to regenerate plants of this endangered species by somatic embryogenesis and organogenesis from meristematic nodules, induced by MS medium supplemented with zeatin (Zn) and indole-3-acetic acid (IAA). Globular structures were induced on the surface of the explants after 2 weeks and after 6–7 weeks of culture, multiple shoots developed from the nodules. Morpho-histological analysis of light green globular, heart-shaped structures resembling somatic embryos revealed, however, that these were organogenic, with strongly vacuolated parenchymatous cells surrounded by a single layer of epithermal cells, and tracheid elements, but no root pole. Milky-white callus also developed around the nodules after 4–6 weeks. Morpho-histological analysis of the globular, heart-, and torpedo-shaped stages of regenerants present in this callus confirmed the development of somatic embryos in the milky-white structures, characterized by deeply staining, small cells with rich cytoplasm, very little vascular tissue in the developing embryos, and no vascular connection with the surrounding callus. The highest rooting frequency (93.33%) was achieved on MS medium containing 1.5 mg/l NAA. Plantlets were acclimatized and successfully transferred to pots. Our results provide a plant regeneration system with potential for germplasm conservation of endangered plants and the rapid propagation and molecular breeding of P. tongkangensis.
