Aims: To evaluate the adverse effect and survival outcome of weekly and triweekly cisplatin with radiotherapy in treatment of cervical cancer. Methods: After an extensive literature search between 1995-2011, we analyzed 7 studies to compare weekly cisplatin and triweekly cisplatin combined radiotherapy. Results: Our analysis established that weekly cisplatin has a lower risk of hematologic toxicity than triweekly cisplatin with concurrent radiotherapy in the treatment of cervical cancer. However, there were no differences in progression free survival and overall survival between weekly cisplatin and triweekly cisplatin (p>0.05). Conclusions: Weekly cisplatin combined with concurrent radiation has lower risk in hematologic toxicity than triweekly cisplatin, but does not improve survival. Triweekly cisplatin treatment has longer intervals and is therefore more convenient. Clinicians and patients can choose either weekly cisplatin or triweekly cisplatin combined radiotherapy for cervical cancer.

Chlamydophila psittaci is an important intracellular pathogen. Persistent infection is an important state of the host-parasite interaction in this chlamydial infection, which plays a significant role in spreading the organism within animal populations and in causing chronic chlamydiosis and serious sequelae. In this study, a C. psittaci persistent infection cell model was induced by penicillin G, and real-time quantitative PCR was used to study the transcriptional levels of 10 C. psittaci genes (dnaA, dnaK, ftsW, ftsY, grpE, rpsD, incC, omcB, CPSIT_0846, and CPSIT_0042) in acute and penicillin-G-induced persistent infection cultures. Compared with the acute cultures, the penicillin-G-treated cultures showed a reduced chlamydial inclusion size and a significantly decreased number of elementary body particles. Additionally, some enlarged aberrant reticulate body particles were present in the penicillin- G-treated cultures but not the acute ones. The expression levels of genes encoding products for cell division (FtsW, FtsY) and outer membrane protein E encoding gene (CPSIT_0042) were downregulated (p < 0.05) from 6 h post-infection onward in the persistent infection cultures. Also from 6 h post-infection, the expression levels of DnaA, DnaK, IncC, RpsD, GrpE, and CPSIT_0846 were upregulated (p < 0.05); however, the expression level of OmcB in the persistent infection was almost the same as that in the acute infection (p > 0.05). These results provide new insight regarding molecular activities that accompany persistence of C. psittaci, which may play important roles in the pathogenesis of C. psittaci infection.

A novel bright-green leaf mutant, bgl11, derived from Nipponbare (Oryza sativa L. ssp. japonica) treated by ethyl methanesulfonate (EMS), exhibited a distinct brightgreen leaf phenotype throughout development. Chlorophyll contents of bgl11 decreased significantly than that of its wild-type parent. Genetic analysis suggested that the brightgreen leaf trait was controlled by a single recessive nuclear gene, which was tentatively designed as BGL11(t). To isolate the BGL11(t) gene, a map-based cloning strategy was employed, and the gene was finally mapped in a 94.7 kb region between marker InDel11-5 and InDel11-9 on the long arm of chromosome 11, in which no gene leaded to leaf-color mutation had been mapped or cloned. Cloning and sequencing analysis revealed that, LOC_Os11g38040, which was predicted to encode an expressed protein, had a 9 bp segment deletion in the coding region of bgl11. Furthermore, the transgenic plants with wild-type gene LOC_Os11g38040were restored to normal phenotype. Accordingly, the gene (LOC_Os11g38040) was identified as the BGL11(t) gene. These results are very valuable for further study on BGL11(t)gene and illuminating the mechanism of chloroplast development in rice.

A mobile Rayleigh Doppler wind LIDAR at an eye-safe wavelength of 355 nm incorporating double-edge technique with triple-channel Fabry-Perot etalon is developed for wind measurement from 5to 40km. The structure of this LIDAR system is described. An intercomparsion experiment with rawinsonde is made, showing good agreement with expected measurement accuracy. A continuous observation of stratosphere wind field for several days with temporal resolution of 15 min and spatial resolution of 200 m from 5 to 40 km is presented, demonstrating the stability and robustness of the LIDAR. A stratospheric quasi-zero wind layer can be found at around 20 km with a direction change from east to west evident in the continuous observation.

Thermo-sensitive genic male sterile (TGMS) lines can provide new options for hybrid seed production using "two-line" system. A set of F2 and BC1 populations derived from the cross between Qiong-6ms and Dan958 were employed to analyze the inheritance of a TGMS line Qiong-6ms and map the TGMS genes in maize. The results demonstrated that the sterility of Qiong-6ms was governed by two duplicative recessive genes, named tms1 and tms2. The gene tms1 was mapped to chromosome 5 linked with the SSR markers umc1355, umc2302 and umc1784 at a distance of 3.0 cM, 1.3 cM and 0.9 cM respectively; while tms2 was localized on chromosome 3, linked with SSR markers bnlg1605 (0.5 cM) and umc2050 (4.2 cM). These markers, which are tightly linked with the tms1 and tms2 genes, will be helpful for marker assisted selection of TGMS lines in maize.

The beam string structure (BSS) has been widely applied to public buildings (e.g. sports venues and exhibition centers) for its strong adaptability to architectural form and reasonable load bearing mechanism. However, most mathematical calculation methods for BSS are too complicated to be generally mastered by structural engineers, which limits the promotion and actual application. In this paper, two analytical calculation methods for the BSS are proposed based on displacement control objectives and work-energy principle. The computational formulas are then derived to calculate the member internal force and structural deformation. On this basis, the tension and static load tests and the fi nite element analytical method have been carried out to assess the calculation methods. The results of the tests and simulation are in good agreement with the analytical solution obtained by the computational formulas. Moreover, the formulas can be more appropriate with a greater beam span, proper rise–span and sag–span ratios (between 1/15 and 1/12) as well as more brace struts.

The effects of cooling medium temperatures and plastic/rubber ratios on solidification and crystallization kinetics of dynamically-vulcanized polypropylene/ethylene-propylene-diene rubber (PP/EPDM) blends were investigated with the aid of an in-situ measurement technique. The cooling medium temperature heavily influenced the solidification kinetics primarily due to a combination of latent heat liberated from the molten polymer and the heat transferred away via the metallic wall during the cooling period. Interestingly, the parameter C in three-parameter model was not only affected by the material properties, but also by the cooling condition, different from the previous literature. The crystallization kinetics analysis indicated that the effect of EPDM in the blends consisted of both nucleation-promoting effect (low EPDM loading) and steric effect (higher EPDM loading). The present kinetic analysis may be helpful to further studies on improving the product performances for industrial applications.

In general, drone honey bees are haploid and develop from unfertilized eggs. However, a diploid drone can arise in an inbred colony. In this study, the morphological characteristics and gene expression profile of the haploid and diploid drones of Apis cerana were analyzed to reveal the differences between them. The ploidy level of the droneswas identified by FlowCytometry (FCM). The characters of the forewings,wetweight of reproductive organs and of newly emerged drones, were investigated. Then, a high throughput transcriptomic analysis was performed using RNA-seq in diploid and haploid drones. The results showed that the wet weight and reproductive organs of diploid droneswere significantly lighter than those of haploid drones. About 201 million high-quality reads were generated from RNA-seq, and 75.99–78.12% of the data weremapped to Apis cerana genome. 360 genes were differentially expressed between diploid and haploid drone, with 152 up-regulated and 208 downregulated in the diploid drones. Functional analysis identified that these genes were significantly enriched in 28 pathways. Comparative transcriptomic analysis detected several differentially expressed genes, which lay a foundation for future studies on molecular mechanisms underlying biology difference in drones in Apis cerana.

Spectraplakins are crucially important communicators, linking cytoskeletal components to each other and cellular junctions. Microtubule actin crosslinking factor 1 (MACF1), also known as actin crosslinking family 7 (ACF7), is a member of the spectraplakin family. It is expressed in numerous tissues and cells as one extensively studied spectraplakin. MACF1 has several isoforms with unique structures and well-known function to be able to crosslink F-actin and microtubules. MACF1 is one versatile spectraplakin with various functions in cell processes, embryo development, tissue-specific functions, and human diseases. The importance of MACF1 has become more apparent in recent years. Here, we summarize the current knowledge on the presence and function of MACF1 and provide perspectives on future research of MACF1 based on our studies and others. [BMB Reports 2016; 49(1): 37-44]

Purpose: To investigate the diet of patients with cervical cancer and precancerosis in the Wufeng area, a high-incidence region in China. Methods: In the case group, 104 patients diagnosed with cervical cancer or cervical intraepithelial neoplasias (CINII/III) were recruited from the Wufeng area. Nine hundred thirty-six healthy women were selected from the same area as the matched controls. A questionnaire, which included questions about general lifestyle conditions, smoking and alcohol status, source of drinking water, green tea intake, and diet in the past year, was presented to all participants. Results: Green tea intake (P=0.022, OR=0.551, 95% CI=0.330-0.919) and vegetable intake (P=0.035, OR=0.896, 95% CI=0.809-0.993) were identified as protective factors against cervical cancer or CINII/III. There was no indication of any associations of other lifestyle factors (smoking status, alcohol status, source of drinking water) or diet (intake of fruit, meat/egg/milk, soybean food, onion/garlic, staple food and pickled food) with cervical cancer. Conclusions: The results suggest that eating more fresh vegetables and drinking more green tea may help to reduce the risk of cervical cancer or CINII/III in people of the Wufeng area.
