  abstract  = {{\"U}bergewicht, das als Volkskrankheit ein wachsendes globales Problem darstellt, ist mit mehreren folgenreichen Komorbidit{\"a}ten behaftet und die Assoziation der Erkrankung mit nachweisbarer Sch{\"a}digung des Erbguts durch oxidativen Stress ist mittlerweile unangefochten. In der vorliegenden Studie wurden periphere Lymphozyten stark bis morbid adip{\"o}ser Patienten mit Hilfe des Mikrokern-Assays untersucht und es konnte - begleitend zu der zu erwartenden BMI-Abnahme - eine signifikante Reduktion des Genomschadens durch Magenbypass bzw. Sleeve-Gastrektomie 12 Monate postoperativ detektiert werden. Daneben demonstrierte die Analyse zus{\"a}tzlich erhobener Patientendaten, die u. a. N{\"u}chternglucose, HbA1c, Blutdruck und Herzfrequenz sowie ein Blutbild der Patienten (inklusive CRP als Entz{\"u}ndungsmarker, Transaminasen, gGT sowie Lipidprofil) umfasste, eine deutliche Besserung vieler Parameter bis auf teilweise wieder physiologische Normwerte. All diese Ergebnisse st{\"u}tzen die These der metabolischen Wirksamkeit sowohl des Roux-en-Y-Magenbypass als auch der Sleeve- Gastrektomie. Ihre Bedeutung liegt nicht zuletzt in der angenommenen Reduktion des Krebserkrankungsrisikos, da jeweils ein Zusammenhang mit der Adipositas an sich, dem Diabetes und durch oxidativen Stress verursachter DNA-Sch{\"a}digung besteht. Mit Blick auf eine gegenw{\"a}rtig in der Forschung diskutierte potentielle therapeutische Anwendung von Antioxidantien zur Reduktion von Erbgutsch{\"a}digungen, die durch oxidativen Stress zustande kommen, wurden die Substanzen Tricetinidin, Curcumin und Resveratrol im Rahmen des Mikrokerntests an HL60- und NRK-Zellen untersucht, in denen mit der Mischung aus Insulin und Angiotensin II eine gentoxische Wirkung erzielt worden war.},

  abstract  = {Eczema often precedes the development of asthma in a disease course called the 'atopic march'. To unravel the genes underlying this characteristic pattern of allergic disease, we conduct a multi-stage genome-wide association study on infantile eczema followed by childhood asthma in 12 populations including 2,428 cases and 17,034 controls. Here we report two novel loci specific for the combined eczema plus asthma phenotype, which are associated with allergic disease for the first time; rs9357733 located in EFHC1 on chromosome 6p12.3 (OR 1.27; P = 2.1 x 10(-8)) and rs993226 between TMTC2 and SLC6A15 on chromosome 12q21.3 (OR 1.58; P = 5.3 x 10(-9)). Additional susceptibility loci identified at genome-wide significance are FLG (1q21.3), IL4/KIF3A (5q31.1), AP5B1/OVOL1 (11q13.1), C11orf30/LRRC32 (11q13.5) and IKZF3 (17q21). We show that predominantly eczema loci increase the risk for the atopic march. Our findings suggest that eczema may play an important role in the development of asthma after eczema.},

  abstract  = {The number of bariatric surgeries being performed worldwide has markedly risen. While the improvement in obesity-associated comorbidities after bariatric surgery is well-established, very little is known about its impact on cancer risk. The peripheral lymphocyte micronucleus test is a widely used method for the monitoring of chromosomal damage levels in vivo, and micronucleus frequency positively correlates with cancer risk. Therefore, the aim of this study was to compare the micronucleus frequency before and after bariatric surgery in obese subjects. Peripheral blood mononuclear cells were collected from 45 obese subjects before and at two time-points after bariatric surgery (6 and 12 months) to assess spontaneous micronucleus frequency. Consistent with the increased cancer risk previously shown, bariatric surgery-induced weight loss led to a significant reduction in lymphocyte micronucleus frequency after 12 months. Interestingly, comorbidities such as type 2 diabetes mellitus and metabolic syndrome further seemed to have an impact on the lymphocyte micronucleus frequency. Our findings may indicate a successful reduction of cancer risk in patients following weight loss caused by bariatric surgery.},
