Expression of most retrotransposons in human blood correlates with biological aging.

Retrotransposons (RTEs) have been postulated to reactivate with age and contribute to aging through activated innate immune response and inflammation. Here, we analyzed the relationship between RTE expression and aging using published transcriptomic and methylomic datasets of human blood. Despite no observed correlation between RTE activity and chronological age, the expression of most RTE classes and families except short interspersed nuclear elements (SINEs) correlated with biological age-associated gene signature scores.

Rectus Muscle Flap-augmented Closures in Wide-gap Exstrophy Bladder.

Background: Wound dehiscence is one of the main complications in complete primary repair of exstrophy (CPRE). In our pediatric urology unit, we have switched to the use of inferior epigastric artery based rectus abdominis flap cover for abdominal wall closure in addition to measures like osteotomy and postoperative hip spica.

Aim: to assess the efficacy of Recus abdominis flap in prevenion of wound dehisence.

Guidelines for the diagnosis and management of adult aplastic anaemia: A British Society for Haematology Guideline.

Pancytopenia with hypocellular bone marrow is the hallmark of aplastic anaemia (AA) and the diagnosis is confirmed after careful evaluation, following exclusion of alternate diagnosis including hypoplastic myelodysplastic syndromes. Emerging use of molecular cyto-genomics is helpful in delineating immune mediated AA from inherited bone marrow failures (IBMF). Camitta criteria is used to assess disease severity, which along with age and availability of human leucocyte antigen compatible donor are determinants for therapeutic decisions.
