Mice deficient in the DNA excision-repair gene Ercc1 (Ercc1∆/-) show numerous accelerated ageing features that limit their lifespan to 4-6 months. They also exhibit a 'survival response', which suppresses growth and enhances cellular maintenance. Such a response resembles the anti-ageing response induced by dietary restriction (also known as caloric(More)
Streptococcus pneumoniae (pneumococcus [Pn]) can be cultured from up to 50% of acute otitis media (AOM) effusions, and these bacteria are the most common cause of AOM-related complications. With the recent advent of antibiotic-resistant Pn strains, treatment of Pn infections may meet with serious difficulties. Prevention through vaccination, notably for the(More)
Early life exposure to endocrine disrupting compounds has been linked to chronic diseases later in life, like obesity and related metabolic disorders. We exposed C57BL/6JxFVB hybrid mice to the aryl hydrocarbon receptor agonist 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and the constitutive androstane receptor/pregnane X receptor agonist polychlorinated(More)
Pertussis, caused by infection with the gram negative B. pertussis bacterium, is a serious respiratory illness that can last for months. While B. pertussis infection rates are estimated between 1-10% in the general population, notifications of symptomatic pertussis only comprise 0.01-0.1% indicating that most individuals clear B. pertussis infections(More)
BACKGROUND In no other European country has the privatisation of hospitals taken such dimensions in the last 15 years as in Germany. Thereby a higher efficiency of private ownership is often assumed as a potential driver. OBJECTIVE The aim of this study is to analyse the current state of research on the question of whether private hospitals are more(More)
Ku80 and DNA-PKCS are both involved in the repair of double strand DNA breaks via the nonhomologous end joining (NHEJ) pathway. While ku80-/- mice exhibit a severely reduced lifespan and size, this phenotype is less pronounced in dna-pkcs-/- mice. However, these observations are based on independent studies with varying genetic backgrounds. Here, we(More)
