    Unitarity Bounds on Dark Matter Effective Interactions at LHC

    Get PDF
    The perturbative unitarity bound is studied in the monojet process at LHC. The production of the dark matter is described by the low-energy effective theory. The analysis of the dark matter signal is not validated, if the unitarity condition is violated. It is shown that the current LHC analysis the effective theory breaks down, at least, when the dark matter is lighter than O(100) GeV. Future prospects for s\sqrt{s} = 14 TeV are also discussed. The result is independent of physics in high energy scales.Comment: 14 pages, 12 figures; v2: footnotes and references are added; figures are slightly change

    One time a day mometasone/indacaterol fixed-dose combination versus two times a day fluticasone/salmeterol in patients with inadequately controlled asthma:pooled analysis from PALLADIUM and IRIDIUM studies

    BACKGROUND: Despite currently available standard-of-care inhaled corticosteroid (ICS)/long-acting β(2)-agonist therapies, a substantial proportion of patients with asthma remain inadequately controlled. This pooled analysis evaluated efficacy and safety of mometasone furoate/indacaterol acetate (MF/IND) versus fluticasone propionate/salmeterol xinafoate (FLU/SAL) in patients with inadequately controlled asthma. METHODS: This analysis included patients from PALLADIUM (NCT02554786) and IRIDIUM (NCT02571777) studies who received high-dose MF/IND (320/150 µg) or medium-dose MF/IND (160/150 µg) one time a day or high-dose FLU/SAL (500/50 µg) two times a day for 52 weeks. Reduction in asthma exacerbations, improvement in lung function, asthma control, and safety were evaluated for 52 weeks. RESULTS: In total, 3154 patients (high-dose MF/IND, n=1054; medium-dose MF/IND, n=1044; high-dose FLU/SAL, n=1056) were included. High-dose MF/IND showed 26%, 22% and 19% reductions in rate of severe, moderate or severe, and all (mild, moderate and severe) exacerbations versus high-dose FLU/SAL, respectively, over 52 weeks (all, p<0.05). High-dose MF/IND improved trough FEV(1) versus high-dose FLU/SAL at weeks 26 (Δ, 43 mL, p=0.001) and 52 (Δ, 51 mL, p<0.001). Reductions in asthma exacerbation rate and improvement in trough FEV(1) with medium-dose MF/IND were comparable with high-dose FLU/SAL over 52 weeks. All treatments improved Asthma Control Questionnaire-7 score from baseline to 52 weeks with no difference between treatments. Safety was comparable between high-dose MF/IND and high-dose FLU/SAL. CONCLUSIONS: One time a day, single-inhaler, high-dose MF/IND reduced asthma exacerbations and improved lung function versus two times a day, high-dose FLU/SAL in patients with inadequately controlled asthma. Similarly, improved outcomes were seen with one time a day, medium-dose MF/IND and two times a day, high-dose FLU/SAL, but at a lower ICS dose

    OBJECTIVE:To evaluate the clinical efficacy and tolerability of intravenous (i.v.) and intraperitoneal (i.p.) paclitaxel combined with S-1, "an oral fluoropyrimidine derivative containing tegafur, gimestat, and otastat potassium" in chemotherapy-naive pancreatic ductal adenocarcinoma (PDAC) patients with peritoneal metastasis.BACKGROUND:PDAC patients with peritoneal metastasis (peritoneal deposits and/or positive peritoneal cytology) have an extremely poor prognosis. An effective treatment strategy remains elusive.METHODS:Paclitaxel was administered i.v. at 50 mg/m and i.p. at 20 mg/m on days 1 and 8. S-1 was administered at 80 mg/m/d for 14 consecutive days, followed by 7 days of rest. The primary endpoint was 1-year overall survival (OS) rate. The secondary endpoints were antitumor effect and safety (UMIN000009446).RESULTS:Thirty-three patients who were pathologically diagnosed with the presence of peritoneal dissemination (n = 22) and/or positive peritoneal cytology (n = 11) without other organ metastasis were enrolled. The tumor was located at the pancreatic head in 7 patients and the body/tail in 26 patients. The median survival time was 16.3 (11.47-22.57) months, and the 1-year survival rate was 62%. The response rate and disease control rate in assessable patients were 36% and 82%, respectively. OS in 8 patients who underwent conversion surgery was significantly higher than that of nonsurgical patients (n = 25, P = 0.0062). Grade 3/4 hematologic toxicities occurred in 42% of the patients and nonhematologic adverse events in 18%. One patient died of thrombosis in the superior mesenteric artery.CONCLUSIONS:This regimen has shown promising clinical efficacy with acceptable tolerability in chemotherapy-naive PDAC patients with peritoneal metastasis

    新型コロナウイルス排出と粘膜抗体の関係を解明 --呼吸器ウイルスのヒト間伝播を制御・予防する第一歩--. 京都大学プレスリリース. 2023-12-25.Articles: Infectious virus shedding duration reflects secretory IgA antibody response latency after SARS-CoV-2 infection. 京都大学プレスリリース. 2023-12-25.Infectious virus shedding from individuals infected with severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) is used to estimate human-to-human transmission risk. Control of SARS-CoV-2 transmission requires identifying the immune correlates that protect infectious virus shedding. Mucosal immunity prevents infection by SARS-CoV-2, which replicates in the respiratory epithelium and spreads rapidly to other hosts. However, whether mucosal immunity prevents the shedding of the infectious virus in SARS-CoV-2-infected individuals is unknown. We examined the relationship between viral RNA shedding dynamics, duration of infectious virus shedding, and mucosal antibody responses during SARS-CoV-2 infection. Anti-spike secretory IgA antibodies (S-IgA) reduced viral RNA load and infectivity more than anti-spike IgG/IgA antibodies in infected nasopharyngeal samples. Compared with the IgG/IgA response, the anti-spike S-IgA post-infection responses affected the viral RNA shedding dynamics and predicted the duration of infectious virus shedding regardless of the immune history. These findings highlight the importance of anti-spike S-IgA responses in individuals infected with SARS-CoV-2 for preventing infectious virus shedding and SARS-CoV-2 transmission. Developing medical countermeasures to shorten S-IgA response time may help control human-to-human transmission of SARS-CoV-2 infection and prevent future respiratory virus pandemics

    Association of FTO genotype with obesity and bone health among communitydwelling adults ; Goto Island study on bone health

    Bone mass is tuned by various factors, including aging, menopause, low body weight, and genetic variations. Here, we showed an independent association between a genotype on the fat mass- and obesity-associated FTO gene (#610966 on OMIM) and bone loss after adjusting for age and body mass index (BMI). A cross-sectional study was nested in a prospective observational study of 1,828 participants (median age: 69 [62-76] years in men and 68 [61-75] years in women) residing in a rural city in western Japan (Goto Island study). Participants were recruited during medical checkups in 2014 and 2016 from the community-dwelling population. The bone mass of the calcaneus was evaluated using quantitative ultrasound. The single nucleotide polymorphism (SNP) rs1421085 was genotyped using a hydrolysis probe. The chi-squared test was used to determine whether the variants were in equilibrium in this population. There were differences in medians of BMI among the genotypes (24.3 in CC, 23.0 in CT, and 22.6 in TT, P = 0.01), but not in those of bone mass. There was a significant association between the minor allele (C) and being overweight in a gene dosage-dependent manner (BMI > 25, OR per allele =1.52, 95% CI = 1.07-2.14, P = 0.02 in men, OR = 1.48, 95% CI = 1.16-1.95, P = 0.01 in women). Logistic regression analysis showed a significant protective association in male carriers of the minor allele against low bone mass (QUS T-score less than -2.0) after adjusting for age and BMI in men aged 65-75 years (OR = 0.50, 95% CI = 0.27-0.96, P = 0.036), with no significant association in women.Our study indicated an association between the genetic polymorphism of FTO and bone mass among community-dwelling men aged 65-75 years. The polymorphism may play a role in bone health with higher BMI and other beneficial functions
