Background: The Roma population are an endogamous, genetically isolated, minority population who migrated from North-Western India to Europe from the 10th Century throughout the Byzantine period and continues to the present day. Approximately 10-12 million Romani people reside in segregated settlements in Europe, and smaller populations live in North America and China. In addition to the endogamy, they also practice consanguinity.

Design: Longitudinal study.
Setting: General practice data for five vaccines administered to children (first and second doses of the measles, mumps, and rubella vaccine (MMR1 and MMR2, respectively), rotavirus vaccine, pneumococcal conjugate vaccine (PCV) booster, and six-in-one (DTaP/IPV/Hib/HepB) vaccine covering diphtheria, tetanus, pertussis, polio, type b, and hepatitis B) from the Cover of Vaccination Uptake Evaluated Rapidly dataset in England.
Introduction: Obexelimab is an investigational, bifunctional, non-depleting, humanized monoclonal antibody that binds CD19 and FcγRIIb to inhibit B cells, plasmablasts, and CD19-expressing plasma cells. In clinical trials, intravenous (IV) administration of obexelimab has been well-tolerated, and demonstrated clinical activity in patients with rheumatoid arthritis, systemic lupus erythematosus, and immunoglobulin G4-related disease. This study was performed to evaluate the pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of obexelimab following subcutaneous (SC) administration, and compare PK/PD profiles between healthy Japanese and non-Japanese volunteers.

The visible absorption spectrum of reveals distinct bands between 320 and 420 nm characteristic of dppn-based ligand-centered transitions, with found to be nonemissive in aqueous solution but weakly luminescent in aerated acetonitrile solution. Transient visible absorption (TrA) spectroscopy reveals that 400 nm excitation of leads to initial population of a ligand-to-metal charge transfer (LMCT) state which evolves within tens of ps to form a dppn-localized intraligand (IL) state which persists for longer than 7 ns and efficiently sensitizes singlet oxygen.
