Delta Np73 has emerged as an interesting novel factor in cancer research. Here, we report the effect of carbon-ion beams on Delta Np73 expression in human cervix carcinoma HeLa cells in contrast to the effect of X-rays. Cellular sensitivities were determined by colony formation. Radiation-induced cell cycle arrest was investigated with flow cytometry. Additionally, radiation-induced apoptosis was analyzed with flow cytometry and Hoechst staining. Furthermore, Delta Np73 expression was examined by semi-quantitative reverse transcription-PCR (semi-quantitative RT-PCR) as well as by Western blot analysis. Following irradiation, stronger G2/M phase arrest, more significant increase in apoptosis and more pronounced Delta Np73 degradation were observed after exposure to high-LET carbon beams in comparison with X-rays at 4 Gy doses. These observations indicate that there is a differential Delta Np73 expression in response to different LET radiations, and down-regulated Delta Np73 expression might play a critical role in promoting cycle arrest and apoptosis in cancer cells. This study highlights the potential of Delta Np73 in radiotherapy. (C) 2012 Elsevier B.V. All rights reserved.

Optical trapping force on a stratified chiral particle by high-order Bessel beam

Jing Bai, Xuan Liu, Cheng-xian Ge, Zhen-sen Wu, Xiao-xiao Zhang

Summary: We studied the optical trapping force exerted on non-uniform chiral stratified spheres using a high-order Bessel beam. By comparing with existing reference, we validated the present theories. Numerical simulations considering various parameters showed that different chirality distributions significantly affect the trapping characteristics, and a stable three-dimensional capture can be achieved by selecting appropriate incident beam and particle parameters. These theoretical investigations offer an analytical method for understanding the interaction between light and more complex stratified chiral cells, thus providing an encouraging approach for designing better optical manipulation systems.

Electron Beam Third Harmonic Amplification Generates High-Power Tunable Terahertz Radiation

Shaojie Chang, Zhenhua Wu, Diwei Liu, Renbin Zhong, Zhaoyun Duan, Yanyu Wei, Yubin Gong, Min Hu

Summary: A novel method for extracting and amplifying the third harmonic of an electron beam to generate high-power terahertz radiation is presented. This approach utilizes three planar grating structures operating in the backwave region to extract and amplify the electron beam from the fundamental modulation, resulting in an amplified output of the fundamental wave and a high power output of the fundamental triplet frequency. The planar grating structure is easier to machine and assemble compared to conventional harmonic amplifiers and allows for increased electron beam flow rate.

Cu donor material assisted friction stir welding of AA2024 and AA6061 dissimilar alloys: Effect on downward force, temperature profile, and mechanical properties

Srinivasa Naik Bhukya, Zhenhua Wu, Abdelmageed Elmustafa, Aiman Al-Allaq, Manish Ojha, Yousuf Mohammed

Summary: This research investigates the effects of copper (Cu) donor material assisted friction stir welding (FSW) on AA2024-T4 and AA6061-T6 plates of 6.35 mm thickness. By introducing Cu donor material, the downward force generated during FSW process is gradually decreased, and the temperature at the beginning of welding process is increased. Defect-free joints with improved tensile strength can be obtained by placing high strength AA2024 alloy at the advancing side of the weld with 25% thick donor material. SEM Fractography images confirm mixed modes of brittle and ductile fracture surfaces after the inclusion of donor material in FSW.

Jing Bai, Xuan Liu, Cheng-Xian Ge, Zhen-Sen Wu, Xiao-Xiao Zhang

Summary: Interactions between collective multi-layered cells and an off-axis high-order Bessel beam (HOBB) were studied. The generalized Lorenz-Mie theory was used to derive the expansion of HOBB. Multiple scattering of collective multi-layered nanoparticles was obtained based on the additional theorem and considering the tangential continuous boundary conditions. The effectiveness of the present theory and codes was proven by comparing with simulations obtained from CST software. Numerical results regarding the effects of various parameters on the scattering of aggregated multi-layered particles were displayed, which may contribute to understanding the optical scattering characteristics of complex-shaped aggregated multi-layered biological cells and have important applications in manipulating multi-layered biological structures.

Genome-wide regulation of Pol II, FACT, and Spt6 occupancies by RSC in Saccharomyces cerevisiae

Emily Biernat, Mansi Verma, Chhabi K. Govind

Summary: RSC is an essential ATP-dependent chromatin remodeling complex in Saccharomyces cerevisiae. It regulates nucleosome-depleted regions (NDRs) by sliding flanking nucleosomes away from NDRs. Depletion of RSC leads to nucleosome encroachment in NDRs and transcription initiation defects. The study compared the effects of catalytic-dead Sth1 and rapid depletion of Sth1 on transcription. Rapid depletion of Sth1 reduces recruitment of TBP and Pol II, while the catalytic-dead mutant exhibits a severe reduction in TBP binding but accumulates Pol II in coding regions. The results suggest a role for RSC in transcription elongation and termination processes.

miR-124-3p regulates the involvement of Ptpn1 in testicular development and spermatogenesis in mouse

Lvjing Luo, Lishuang Sun, Shu Li, Huiting Liu, Zhengyu Chen, Shi Huang, Yinyin Mo, Genliang Li

Summary: This study analyzed the expression of Ptpn1 and miR-124-3p in testicular tissues of mice and investigated their regulatory relationship. The results showed that Ptpn1 expression was up-regulated in adult mouse testis compared to juvenile mouse testis, while miR-124-3p expression showed an opposite pattern. Further analysis suggested that the down-regulation of miR-124-3p may contribute to the high expression of Ptpn1 in adult mouse testis.
