We introduce a new index I_{Delta m_{31}^2} to find where is the better setup of the baseline length and energy to avoid as well as possible the uncertainty from the correlation between Delta m_{31}^2 and cos(delta) in nu_mu --> nu_mu long baseline experiments.Comment: 6 pages, 9 figure

Nedaplatin: A Radiosensitizing Agent for Patients with Cervical Cancer

Despite the recent advances in the management of cervical cancer using cisplatin-based concurrent chemoradiotherapy, substantial treatment failure still occurs, especially in advanced-stage patients and early-stage cervical cancer patients with high-risk prognostic factors. Therefore, efforts to further improve the survival and quality of life of these patients are necessary. Nedaplatin (cis-diammine-glycoplatinum), a derivative of cisplatin, was developed with the aim of producing a treatment with a similar effectiveness to cisplatin but decreased renal and gastrointestinal toxicities. Based on the promising results of preclinical studies, the clinical efficacy of nedaplatin as a radiosensitizing agent was evaluated in patients with cervical cancer. Retrospective analysis of nedaplatin-based concurrent chemoradiotherapy (CCRT) against cervical cancer suggested that nedaplatin-based CCRT can be considered as an alternative to cisplatin-based CCRT in both early-stage and advanced-stage cervical cancer patients. However, due to the lack of a randomized controlled study, nedaplatin-based CCRT has not been convincingly proven to be clinically effective in patients with cervical cancer. Further investigations in randomized controlled trials are therefore needed

Molecular Cloning and Sequence Analysis of the cDNAs Encoding Toxin-Like Peptides from the Venom Glands of Tarantula Grammostola rosea

Tarantula venom glands produce a large variety of bioactive peptides. Here we present the identification of venom components obtained by sequencing clones isolated from a cDNA library prepared from the venom glands of the Chilean common tarantula, Grammostola rosea. The cDNA sequences of about 1500 clones out of 4000 clones were analyzed after selection using several criteria. Forty-eight novel toxin-like peptides (GTx1 to GTx7, and GTx-TCTP and GTx-CRISP) were predicted from the nucleotide sequences. Among these peptides, twenty-four toxins are ICK motif peptides, eleven peptides are MIT1-like peptides, and seven are ESTX-like peptides. Peptides similar to JZTX-64, aptotoxin, CRISP, or TCTP are also obtained. GTx3 series possess a cysteine framework that is conserved among vertebrate MIT1, Bv8, prokineticins, and invertebrate astakines. GTx-CRISP is the first CRISP-like protein identified from the arthropod venom. Real-time PCR revealed that the transcripts for TCTP-like peptide are expressed in both the pereopodal muscle and the venom gland. Furthermore, a unique peptide GTx7-1, whose signal and prepro sequences are essentially identical to those of HaTx1, was obtained

Measuring the Leptonic CP Phase in νμ→νμ\nu_{\mu} \to \nu_{\mu} Oscillations

In $\nu_{\mu} \to \nu_{\mu}$ oscillations, we find that the effect of the CP phase $\delta$ becomes large in the region $E2000$ km. In this region, the change of the probability in this channel reaches about 0.4 due to the CP phase effect beyond our expectation in the case of large 1-3 mixing angle. Furthermore, the CP phase effect have almost same sign over the region $E>0.5$ GeV so that one may find the signal of CP violation by measuring the total rate only. As an example, we use an experimental setup and demonstrate that the allowed region is limited to one by combined analysis of $\nu_e$ and $\nu_{\mu}$ events although there remain three allowed regions by the analysis of $\nu_e$ events alone.Comment: 7 pages, 8 figures, version to appear in PL

Dynamics of poles with position-dependent strengths and its optical analogues

The dynamics of point vortices is generalized in two ways: first by making the strengths complex, which allows for sources and sinks in superposition with the usual vortices, second by making them functions of position. These generalizations lead to a rich dynamical system, which is nonlinear and yet has conservation laws coming from a Hamiltonian-like formalism. We then discover that in this system the motion of a pair mimics the behavior of rays in geometric optics. We describe several exact solutions with optical analogues, notably Snell's law and the law of reflection off a mirror, and perform numerical experiments illustrating some striking behavior.Comment: 10 page

Feasibility and Efficacy of Definitive Radiotherapy with 66 Gy and Concurrent Carboplatin-Paclitaxel Chemotherapy for Stage III Non-Small Cell Lung Cancer.

Purpose/Objectives : This study was conducted to assess the feasibility and efficacy of definitive radiotherapy (RT) with a total dose of 66 Gy and concurrent carboplatin-paclitaxel chemotherapy for patients (pts) with stage Ⅲ non-small celllung cancer. Materials/Methods : Between April 2007 and December 2013，99 pts with non-small cell lung cancer were treated using RT with concurrent carboplatin-paclitaxel chemotherapy in our hospital. Sixty-eight of them received RT with a total dose of 66 Gy. We analyzed 46 Stage Ⅲ pts who had been treated with RT using three-dimensional radiotherapy treatment planning. The prophylactic mediastinal lymph nodes were included in the clinical target volume for RT. The survival rate after the start of RT was estimated using the Kaplan-Meier method. We estimated the cumulative local failure and distant metastasis rates with the Fine-Gray method. Adverse events were evaluated according to the CTCAE (v.4.0). Results : The median age of the pts was 70.9 (52.8-78.7) years old (y.o.). The performance status (PS) of each pt was fairly good (ECOG PS 0: 25, PS 1: 20, PS 3:1), and their clinical stages (UICC 7th) were twenty-nine Ⅲ A and seventeen Ⅲ B. Diagnoses were pathologically confirmed in 32 pts. The median follow-up period was 35.7 (2.0-82.2) months among all pts, and 55.9 (40.1-82.2) months among survivors. The 3- and 5-year Kaplan-Meier overall survival rates were 52.2 and 34.0%，respectively, and the median survival time was 36.6 months. The 3- and 5-year Kaplan-Meier progression-free survival rates were 29.1 and 21.9%，respectively, and the median progression-free survival time was 9.9 months. The 5-year local failure rate was 37.6%, and the 5-year distant metastasis rate was 49.7%. Sixteen (34.8%) pts required steroid administration because of radiation pneumonitis (CTCAE Grade 2 or higher) and two of them died (Grade 5). No other severe non-hematologic toxicity (Grade 3 or higher) was observed. Conclusion : These results suggest that definitive RT with a total dose of 66 Gy and concurrent carboplatin-paclitaxel chemotherapy is feasible and may be promising for pts with Stage Ⅲ non-small cell lung cancer

Two Distinct Pathways to Development of Squamous Cell Carcinoma of the Vulva

Squamous cell carcinoma (SCC) accounts for approximately 95% of the malignant tumors of the vaginal vulva and is mostly found in elderly women. The future numbers of patients with vulvar SCC is expected to rise, mainly because of the proportional increase in the average age of the general population. Two different pathways for vulvar SCC have been put forth. The first pathway is triggered by infection with a high-risk-type Human Papillomavirus (HPV). Integration of the HPV DNA into the host genome leads to the development of a typical vulvar intraepithelial neoplasia (VIN), accompanied with overexpression of p14ARF and p16INK4A. This lesion subsequently forms a warty- or basaloid-type SCC. The HPV vaccine is a promising new tool for prevention of this HPV related SCC of the vulva. The second pathway is HPV-independent. Keratinizing SCC develops within a background of lichen sclerosus (LS) through a differentiated VIN. It has a different set of genetic alterations than those in the first pathway, including p53 mutations, allelic imbalances (AI), and microsatellite instability (MSI). Further clinical and basic research is still required to understand and prevent vulvar SCC. Capsule. Two pathway for pathogenesis of squamous cell carcinoma of the value are reviewed

Theoretical study on isomerization of α-acids: A DFT calculation

The α-acids contained in hops are one of the ingredients of beer. The isomerization of α-acids produces iso-α-acids, the main source of bitterness in beer. In this study, the isomerization mechanism of the α-acid, cohumulone, was elucidated by using density functional theory in conjunction with the polarizable continuum model or 3D-RISM integral equation theory of liquids. The calculated reaction diagram is consistent with experimental results; the activation free energy difference between the cis and trans isomers is in good agreement with the experimental estimate. The activation energy difference results from solvation energy. Additionally, a calculation of NMR chemical shifts showed that the proton position of isocohumulone is different from that proposed previously. The effect of Mg²⁺ cation on the isomerization was also investigated. Both the activation and reaction free energy are stabilized by the presence of Mg²⁺, which is consistent with experimental results. Water solvation reduces the activation free energy
