EOS 2020: 96th Congress of the European Orthodontic Society is organized by MCI Deutschland GmbH and will be held from Jun 10 - 14, 2020 at Hamburg Exhibition Hall and Congress Ltd., Hamburg, Germany. The aims of EOS are: • To advance all aspects of orthodontics and its relations with the collateral arts and sciences for the public benefit. • To seek the furtherance of orthodontics amongst all branches of the dental profession working in private practice, hospitals and universities throughout Europe. • To bring together each year at an annual congress orthodontists from all over the world. Main Themes: The scientific programme will have two main themes. The first will focus on the role of orthodontics and dentofacial orthopaedics in oral health, bringing into discussion the various treatment effects. Secondly, experts in bone biology and orthodontics will give us an update on the next topic of interest titled “All about bone in orthodontics”. Time will also be devoted to the presentation of new scientific and clinical developments in a variety of other important topics in the free topics section. Description: The two main themes of the scientific programme will focus on the role of orthodontics and dentofacial orthopaedics in oral health. Secondly, experts in bone biology and orthodontics will give us an update on the topic “all about bone in orthodontics”. Also new scientific and clinical developments will be presented in the free topics section. Excellent keynote speakers will critically analyse these subjects, followed by short presentations of new research data. In the era of globalised online information, our annual congress not only aims to provide new scientific information but also to bring together researchers and clinicians from all over the world and to establish long-lasting collaborations and friendships. The large number of participants that attend the EOS meetings every year is the best proof of this. A special invitation is addressed to the future of our discipline, the orthodontic postgraduate students of European and other programmes, to submit and present their research and to make friendships for life in a relaxed and friendly atmosphere.

15th Congress of the European Academy of Paediatric Dentistry is organized by the European Academy of Paediatric Dentistry (EAPD), INTERPLAN Congress, Meeting & Event Management AG, German Society for Pediatric Dentistry eV / Deutsche Gesellschaft fur Kinderzahnheilkunde e.V. (DGKiZ). The session will is held from Jul 01 - 04, 2020 at Hamburg Exhibition Hall and Congress Ltd, Hamburg, Germany. The biannual EAPD congress is one of the significant global meetings in Paediatric Dentistry. The conference is an opportunity for scientists, specialists as well as general practitioners to bestow their experiences and expand their knowledge about the evolving developments in our profession. Additionally, the EAPD conference 2020 presents an ideal framework for international exchange. The scientific program unveils a spectrum of essential and challenging subjects in Paediatric Dentistry. The main topic of the session “Paediatric dentistry in a changing society” will teach special tasks, derived from altered positions of children in our families and societies and the current changes induced by migration in Europe. The second main topic will be “Dental care for medically compromised children” who require vast attention with the emerging progress in medical care for children. The final topic “Biomaterials in Paediatric Dentistry” deals with a core subject in our profession. Main topics will be: • Biomaterials in pediatric dentistry • Dental care for medically compromised children • Pediatric dentistry in a changing society Additional details will be posted as soon as they are available.

AOTrauma Europe Masters Course - Fractures around the Knee is organized by AOTrauma and will be held from Sep 04 - 05, 2020 at Hamburg, Germany. Additional details will be posted as soon as information is available.

Membrane Protein Expression, Purification and Characterisation (mPEPC2) Course is organized by European Molecular Biology Laboratory (EMBL) and will be held from Sep 07 - 14, 2020 at European Molecular Biology Laboratory (EMBL), Hamburg, Germany. Course Overview: Integral membrane proteins (IMPs) are encoded by almost 30% of all open reading frames and provide key functions in the cell. Due to their hydrophobic nature, they are difficult to study and structural information is lacking far behind their soluble counterparts. This EMBO Practical Course will teach participants in the latest developments in membrane protein production, characterisation and structure determination. Modern protein expression techniques using various hosts will be presented and students will get acquainted with new crystallisation and reconstitution techniques. An attitude to combine protein purification and characterisation will be taught to impress the necessity on the students that proteins have to be conditioned with care to achieve structural information. The presence of a crystallisation facility and beamlines for SAXS and macromolecular crystallography at the venue will be employed to perform novel integrated structural biology experiments. The course has an emphasis on practicals in small groups, and a "Meet the scientist" session at the beginning of the course will ensure a close interaction between students and tutors. Modules/Resources: • Expression of integral membrane proteins in eukaryotic hosts • SAXS on integral membrane proteins • Crystallization of integral membrane proteins in lipidic cubic phase • Quality control of integral membrane proteins • Reconstitution of IMPs in a detergent free environment using disc technology • Reconstitution of IMPs in proteoliposomes and functional assays • Bioinformatics on IMPs and modelling of membrane proteins • Crystal harvesting and serial crystallography of small IMP crystals grown in Crystal Direct plates • Electron microscopy of integral membrane proteins (neg. stain and data analysis) Additional details will be posted as soon as information is available.
