A Role for the CAL1-Partner Modulo in Centromere Integrity and Accurate Chromosome Segregation in Drosophila
Chin-Chi Chen, Elizabeth Greene, Sarion R. Bowers, Barbara G. Mellone
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0045094
Abstract: The relationship between the nucleolus and the centromere, although documented, remains one of the most elusive aspects of centromere assembly and maintenance. Here we identify the nucleolar protein, Modulo, in complex with CAL1, a factor essential for the centromeric deposition of the centromere-specific histone H3 variant, CID, in Drosophila. Notably, CAL1 localizes to both centromeres and the nucleolus. Depletion of Modulo, by RNAi, results in defective recruitment of newly-synthesized CAL1 at the centromere. Furthermore, depletion of Modulo negatively affects levels of CID at the centromere and results in chromosome missegregation. Interestingly, examination of Modulo localization during mitosis reveals it localizes to the chromosome periphery but not the centromere. Combined, the data suggest that rather than a direct regulatory role at the centromere, it is the nucleolar function of modulo which is regulating the assembly of the centromere by directing the localization of CAL1. We propose that a functional link between the nucleolus and centromere assembly exists in Drosophila, which is regulated by Modulo.

Abstract: We report the recent phi2/alpha results from Belle with KEKB accelerator and Babar with PEP-II accelerator. The analysis of B->pi pi, B->rho rho and B->rho pi are included in this report. These b->u u_bar d decay modes are related to the CKM angle phi2/alpha and the method of phi2/alpha extraction of corresponding decay are also included. After combining all the decay modes, the constraint of phi2/alpha is 100.2+15.0-8.8 degree.

Computer Science , 2013,
Abstract: We propose a flat nonlinear placement algorithm FFTPL using fast Fourier transform for density equalization. The placement instance is modeled as an electrostatic system with the analogy of density cost to the potential energy. A well-defined Poisson's equation is proposed for gradient and cost computation. Our placer outperforms state-of-the-art placers with better solution quality and efficiency.

Abstract: Using the algebraic method of the theory of angular momentum in quantum mechanics a detailed study is made for the model of s-f interaction of rare-earth metals. A general form of Hamiltonian of s-f interaction is derived. Utilizing the method of the theory of perturbation in operator form we have obtained the general expression for the effective Hamiltonian of f-f interaction through s-f interaction. Retaining terms to the second order of smallness, besides the isotropic exchange interaction the pseudo-dipole interaction is also obtained. On the basis of the results obtained, we have discussed preliminarily the magnetic crystalline anisotropy of the ferromagnetic phase of rare-earth metals. Some experimental facts which might be explained by the above results are indicated.

Abstract: The method of correlation function has been utilized to discuss the nonlinear effects in the ferromagnetic resonance at high power levels. For ordinary ferromagnetic crystals, the present theory includes the results of the semiclassical theory developed by H. Suhl as a classical limit. In the case of YIG doped with rare-earth ions, the frequency shift and the additional losses due to the rare-earth ions have been discussed. Besides, the threshold field of the so-called first order process with parallel pumping and the first and second order processes with perpendicular pumping have also been derived. The results obtained show that the rf critical magnetic field increases with the addition of rare-earth ions. In samples with small concentration of rare-earth ions, the influence on the threshold is attributed to the increase of the losses of spin waves. The temperature dependence and the anisotropy of the threshold field are entirely similar to those of the ferromagnetic resonance linewidth at low power level. The experimental results may be satisfactorily explained by the present theory.

Abstract: The Lyons-Kaplan method is applied to the discussion of the change of spin configuration of a Bravias lattice in the presence of external magnetic field or magnetic anisotropy. It is shown that the antiferromagnetic structure transforms into ferromagnetic ones above a certain critical field and the formula for this critical field is derived. The stability of the corresponding spin configurations is also examined.

Critical Care , 2009, DOI: 10.1186/cc8147
Abstract: A multicenter prospective observational study based on the NSARF (National Taiwan University Surgical ICU Associated Renal Failure) Study Group database. 98 patients (41 female, mean age 66.4 ± 13.9 years) who underwent acute RRT according to local indications for post-major abdominal surgery AKI between 1 January, 2002 and 31 December, 2005 were enrolled The demographic data, comorbid diseases, types of surgery and RRT, as well as the indications for RRT were documented. The patients were divided into early dialysis (sRIFLE-0 or Risk) and late dialysis (LD, sRIFLE -Injury or Failure) groups. Then we measured and recorded patients' outcome including in-hospital mortality and RRT wean-off until 30 June, 2006.The in-hospital mortality was compared as endpoint. Fifty-seven patients (58.2%) died during hospitalization. LD (hazard ratio (HR) 1.846; P = 0.027), old age (HR 2.090; P = 0.010), cardiac failure (HR 4.620; P < 0.001), pre-RRT SOFA score (HR 1.152; P < 0.001) were independent indicators for in-hospital mortality.The findings of this study support earlier initiation of acute RRT, and also underscore the importance of predicting prognoses of major abdominal surgical patients with AKI by using RIFLE classification.Acute kidney injury (AKI) is a common problem in critically ill patients, with a reported incidence of 1 to 25% and a poor prognosis [1,2]. Postoperative AKI is one of the most serious complications in surgical patients [3]. The risk factors of postoperative AKI include emergent surgery [4], exposure to nephrotoxic drugs, hypotension, hypovolemia, hypothermia, inflammatory response to surgery [5,6], and cardiac dysfunction [3]. On the other hand, hospital-acquired infection also contributes to the development of AKI in patients who receive emergent abdominal surgery. The abdominal compartment syndrome, which develops after sustained and uncontrolled intra-abdominal hypertension and may result in AKI or mortality, is being increasingly observed in the gen
