The unreduced (2n) gametes have long been used in triploid breeding of citrus. In lemon, the previously reported mechanisms for 2n megagametophyte formation were controversial, whereas that for 2n pollen production is still unknown. Herein, the frequency of and mechanism underlying 2n megagametophyte and 2n pollen formation in ‘Eureka’ lemon were investigated based on cytological observation and genotyping of the triploid hybrids between ‘Eureka’ lemon and ‘Early gold’ sweet orange. As a result, 4.79% of the viable pollens of ‘Eureka’ lemon were identified as the 2n pollen with a larger diameter (70.16 ± 3.92 μm). The 2n pollen might be resulted from the formation of parallel spindles at meiosis stage II. Among the 204 plantlets regenerated from embryo rescue following the sexual cross, 12 were triploids as identified by flow cytometry. According to the analysis of heterozygosity transmission using 13 pericentromeric single nucleotide polymorphism (SNP) markers and 20 randomly distributed simple sequence repeat (SSR) markers, 11 triploids were identified to be originated from the fertilization of 2n megagametophytes of ‘Eureka’ lemon, with a frequency of 5.39%. Among them, nine 2n megagametophytes were supposed to be arisen from the second division restitution (SDR), whereas the other two were from postmeiotic genome doubling (PMD). These results to understand the mechanism underlying 2n gamete formation in lemon are valuable for its efficient polyploid breeding.

Solar photocatalytic hydrogen production is considered as a potential solution to alleviate the current global energy situation. In this work, a novle CdS spherical nanoparticles/Ti3C2 MXene nanosheet (CM) heterostructure photocatalyst was prepared by in situ growth method, which has the characteristics of high efficiency and stability. The results showed that the CM sam- ple has regular morphology and size. When compared with pure CdS, its specific surface area increased and the hydrogen evolution performance also greatly improved. Among them, the hydrogen evolution of CM-0.06 is 1295 μmol·g−1·h−1 (λ > 420 nm), which is 7 times that of spherical CdS, and it also showed stronger stability. Tight interface contact can promote the transfer and migration of photo-generated carriers, and the effective separation of electron hole pairs can enhance the absorption of visible light. In addition, Ti3C2 MXene acts as an electron trap can further accelerate the separation of pho- togenerated electrons and holes. The synergistic effect between semiconductor CdS and Ti3C2 MXene nanosheets, which provides a new idea for the design of more stable and efficient CdS-based photocatalysts.
Exploring the Attractive Factors of App Icons

More than 1 billion mobile apps (smartphone applications) have been released worldwide. Competition among developers of apps that are available in app stores has intensified because of increasing demand. App icons with an appealing design can instantly increase attention. Miryoku Engineering methods were used and combined with the Kansei interface model to examine the relationship between attractive icons and users. The evaluation grid method (EGM) is a qualitative method that was used to evaluate the icons, and Quantification Theory Type I is a quantitative method that was used to analyze the influence of design elements in icons. Eight attractive factors of app icons were determined using EGM, and six specific factors were identified using questionnaires. The quantitative results indicated that user cognition and emotion were influenced by the various design elements. The impact on the attractive factors of a single design element differed among users with diverse backgrounds. App icons were assessed on the basis of aesthetics to identify attractive factors and thereby assist designers in understanding and implementing design elements and improving the overall visual appeal of their apps. The result of this investigation is crucial to the presentation of app icons in online app stores.

Background/Aims: This was a Phase 2 study (NCT02015793) to evaluate the pharmacokinetics, safety, and efficacy of adalimumab in Chinese patients with Crohn`s disease (CD). Methods: Thirty, adult Chinese patients with CD (CD Activity Index [CDAI] 220-450; high-sensitivity [hs]-C-reactive protein [CRP] ≥3 mg/L) received double-blind adalimumab 160/80 mg or 80/40 mg at weeks 0/2, followed by 40 mg at weeks 4 and 6. An open-label extension period occurred from weeks 8-26; patients received 40 mg adalimumab every other week. Serum adalimumab concentration and change from baseline in fecal calprotectin (FC) were measured during the double-blind period. Clinical remission (CDAI <150), response (decrease in CDAI ≥70 points from baseline), and change from baseline in hs-CRP were assessed through week 26. Nonresponder imputation was used for missing categorical data and last observation carried forward for missing hs-CRP/FC values. No formal hypothesis was tested. Adverse events were monitored. Results: Mean adalimumab serum concentrations during the induction phase were 13.9-18.1 μg/mL (160/80 mg group) and 7.5-9.5 μg/mL (80/40 mg group). During the double-blind period, higher remission/ response rates and greater reductions from baseline in hs-CRP and FC were observed with adalimumab 160/80 mg compared to that with 80/40 mg. Adverse event rates were similar among all treatment groups. Conclusions: Adalimumab serum concentrations in Chinese patients with CD were comparable to those observed previously in Western and Japanese patients. Clinically meaningful remission rates and improvement in inflammatory markers were achieved with both dosing regimens; changes occurred rapidly with adalimumab 160/80 mg induction therapy. No new safety signals were reported. (Intest Res 2016;14:152-163)

Background: Spontaneous recovery of severe alopecia areata is rare and the condition is difficult to treat. Objective: The aim of this study is to investigate and compare the effects and safety of steroid pulse therapy between oral and intravenous administrations between 1999 and 2010 at the Department of Dermatology, National Cheng Kung University Hospital. Methods: Data were retrospectively retrieved. A satisfactory response was defined as more than 75% hair regrowth in the balding area. Results: A total of 85 patients with more than 50% hair loss were identified and treated, with an overall satisfactory response rate of 51.8%. The mean follow-up time was 37.6 months, with a relapse rate of 22.7%. Patients with alopecia areata (hereafter, AA) of recent onset within one year showed higher response rates (p< 0.001) and lower relapse rates compared to patients with AA persisting for more than 1 year. Further, even in patients with alopecia totalis, alopecia universalis or ophiasis type, early treatment resulted in a satisfactory response rate of 47% among the treated patients. In general, oral therapy was as effective and well-tolerated as intravenous therapy. Conclusion: The response rate is determined by disease severity and time of intervention, not by the administration form of steroid pulse therapy. Oral steroid pulse therapy can be considered as the first-line treatment for patients with severe AA of recent onset within one year. (Ann Dermatol 25(4) 471∼474, 2013)

This paper discusses the problems which should be paid attention to in landscape architecture design. The landscape design is particular about the ideal condition under the Eastern zen thought influence. the so-called ideal condition referring to is the poem, painting, drama and botanical garden, using the artistic technique which displays the creativity, unity of virtue and reality. To display the vitality of universe or the true life meaning profoundly, thus causes the body of aesthetic appreciation"s surmounting perception and being syncretized with nature, and immediately sublimating to a extensive space of artistic condition. Therefore, this article adopts "the ideal condition" to explore the the true meaning of the Eastern historic garden design . Thus obtains the high coordination with nature which manifests "the unity of human and nature" boundary, and takes specially neutral, amiable, contains and the pursuit of deep beauty; Moreover, in the layout and the spatial processing manifests the meaning of the Zen thought, pursuing the unification between man-power and the nature, solemn and implicit, standardized and diversified, even between the principle and the sentiment. All these characteristics make the Japanese classical garden design delicate, graceful, comfortable and applied, and which make it famous for the rich bright felling of rhythm and the unique national artistic feature of style worldwide.
