1Thymoma and autoimmunity显示文摘The thymus is a central lymphatic organ that is responsible for many immunological functions,including the production of mature,functional T cells and the induction of self-tolerance.Benign or malignant tumors may originate from the thymus gland,with thymoma being the most common and accounting for 50% of anterior mediastinal tumors.Malignancies linked to thymoma include the loss of self-tolerance and the presence of autoimmunity.In this review,we compiled the current scientific evidence detailing the various interactions between thymoma and autoimmune diseases,including myasthenia gravis,systemic lupus erythematosus,inappropriate antidiuretic hormone secretion,pure red cell aplasia,pernicious anemia,pemphigus and autoimmune thyroid diseases.In recent years,several mechanisms have been proposed to explain these interactions.Most are based on the assumption that the‘sick’thymus,like the‘normal’thymus,can generate mature T cells;however,the T cells generated by the sick thymus are impaired and thus may exert cellular autoreactivity.Here,we present several theories that may shed light on the loss of self-tolerance associated with this epithelial tumor of the thymus.Shahar Shelly Nancy Agmon-Levin Arie Altman Yehuda Shoenfeld 2011Cellular & Molecular Immunology2011,8,3:19
2Patients with irritable bowel syndrome-diarrhea have lower disease-specific quality of life than irritable bowel syndrome-constipation显示文摘AIM: To determine effect of irritable bowel syndrome(IBS) subtype on IBS-specific quality of life(QOL) questionnaire and its subscales.METHODS: We studied IBS patients visiting our functional gastroenterology disorder clinic at a tertiary care center of Unites States.IBS and IBS subtype were diagnosed using Rome-Ⅲ questionnaire.QOL was assessed using IBS-QOL questionnaire.IBSQOL assesses quality of life along eight subscales: dysphoria,interference with activities,body image,health worry,food avoidance,social reactions,sexual health,and effect on relationships.IBS-QOL and its subscales were both scored on a range of 0-100 with higher scores suggestive of better QOL.Results of overall IBS-QOL scores and subscale scores are expressed as means with 95%CI.We compared mean IBS-QOL score and its subscales among various IBSsubtypes.Analysis of variance(ANOVA) was used to compare the mean difference between more than two groups after controlling for age and gender.A posthoc analysis using Bonferroni correction was used only when P value for ANOVA was less than 0.05.RESULTS: Of 542 patients screened,243 had IBS as per Rome-Ⅲ criteria.IBS-mixed(IBS-M) was the most common IBS subtype(121 patients,49.8%) followed by IBS- diarrhea(IBS-D)(56 patients,23.1%),IBSconstipation(IBS-C)(54 patients,22.2%) and IBSunspecified(IBS-U)(12 patients,4.9%).Overall IBSQOL scores were significantly different among various IBS-subtypes(P = 0.01).IBS-QOL of patients with IBS-D(61.6,95%CI: 54.0-69.1) and IBS-M(63.0,95%CI: 58.1-68.0) was significantly lower than patients with IBS-C(74.5,95%CI: 66.9-82.1)(P = 0.03 and 0.02 respectively).IBS-D patients scored significantly lower than IBS-C on food avoidance(45.0,95%CI: 34.8-55.2 vs 61.1,95%CI: 50.8-71.3,P = 0.04) and interference with activity(59.6,95%CI: 51.4-67.7 vs 82.3,95%CI: 74.1-90.6,P < 0.001).IBS-M patients had more interference in their activities(61.6,95%CI: 56.3-66.9 vs 82.3,95%CI: 74.1-90.6,P = 0.001) and greater impact on their relationships(73.3,95%CI: 68.4-78.2 vs 84.7,95%CI: 77.2-92.2,P = 0.02) than IBS-C patients.Patients with IBS-M also scored significantly lower than IBS-C on food avoidance(47.2,95%CI: 40.7-53.7 vs 61.1,95%CI: 50.8-71.3,P = 0.04) and social reaction(66.1,95%CI: 61.1-71.1 vs 80.0,95%CI: 72.1-87.7,P = 0.005).CONCLUSION: IBS-D and IBS-M patients have lower IBS-QOL than IBS-C patients.Clinicians should recognize food avoidance,effects on daily activities and relationship problems in these patients.Prashant Singh Kyle Staller Kenneth Barshop Elaine Dai Jennifer Newman Sonia Yoon Shahar Castel Braden Kuo 2015World Journal of Gastroenterology2015,21,26:9
3Derivatives of Meromorphic Functions with Multiple Zeros and Elliptic Functions显示文摘Let f be a nonconstant meromorphic function in the plane and h be a nonconstant elliptic function. We show that if all zeros of f are multiple except finitely many and T (r, h) = o{T (r, f )} as r →∞, then f' = h has infinitely many solutions (including poles).Pai YANG Shahar NEVO 2013Acta Mathematica Sinica,English Series2013,29,7:3

5High-Q ring resonators directly written in As2S3 chalcogenide glass films显示文摘Planar ring resonator waveguides are fabricated in thin films of As2S3 chalcogenide glass,deposited on silicaon-silicon substrates.Waveguide cores are directly written by scanning the focused illumination of a femtosecond Ti:sapphire laser at a central wavelength of 810 nm,through a two-photon photo-darkening process.A large photoinduced index change of 0.3–0.4 refractive index units is obtained.The radius of the ring resonator is 1.9 mm,corresponding to a transmission free spectral range of 9.1 GHz.A high loaded(intrinsic) Q value of 110,000(180,000) is achieved.The thermal dependence of the resonator transfer function is characterized.The results provide the first report,to the best of our knowledge,of directly written high-Q ring resonators in chalcogenide glass films,and demonstrate the potential of this simple technique towards the fabrication of planar lightguide circuits in these materials.Shahar Levy Matvei Klebanov Avi Zadok 2015Photonics Research2015,3,3:3

7Ig G4-related disease manifesting as an acute gastric-pericardial fistula显示文摘Ig G4-related disease is a recently recognized entity linked initially to autoimmune pancreatitis and has been subsequently described in nearly every organ system. Men over the age of 50 represent the most affected demographic group and a comprehensive set of diagnostic criteria has been developed to aid treating clinicians. Though elevated levels of Ig G4 in the serum are suggestive of the disease, definitive diagnosis is made on histopathology. Treatment is tailored to the clinical presentation with corticosteroid therapy known to have proven efficacy. Gastric manifestations of the Ig G4-related disease primarily come in two varieties, notably chronic ulceration or pseudotumor formation. Autoimmune pancreatitis conveys increased risk for Ig G4-related disease of the stomach, which is independent of Helicobacter pylori status. In this case report, we present an acute gastric-pericardial fistula secondary to Ig G4-related disease that required urgent operative management. To our knowledge, this is the first report in the medical literature describing this complication of Ig G4-related disease.James Frydman Shahar Grunner Yoram Kluger 2014World Journal of Gastroenterology2014,20,44:2
