Inflammatory signals from fatty bone marrow support DNMT3A driven clonal hematopoiesis.

Both fatty bone marrow (FBM) and somatic mutations in hematopoietic stem cells (HSCs), also termed clonal hematopoiesis (CH) accumulate with human aging. However it remains unclear whether FBM can modify the evolution of CH. To address this question, we herein present the interaction between CH and FBM in two preclinical male mouse models: after sub-lethal irradiation or after castration.

Replication of Varroa destructor virus 1 (VDV-1) and a Varroa destructor virus 1-deformed wing virus recombinant (VDV-1-DWV) in the head of the honey bee.

A country-wide screen for viral pathogens in Israeli apiaries revealed significant incidence of deformed wing virus (DWV) and Varroa destructor-1 virus (VDV-1). To understand these viruses' possible involvement in deformed wing syndrome of honey bees, we studied their replication in symptomatically and asymptomatically infected bees qualitatively and quantitatively, using RT-PCR, quantitative real-time RT-PCR, and immunodetection of the major viral capsid protein VP1. We found, for the first time, replication of VDV-1 and/or a VDV-1-DWV recombinant virus in the heads of recently emerged symptomatic bees.

Improving the nutritional condition of infants and young children undergong hemodialysis.

The growing number of infants receiving HD treatment has led to an increased awareness among the nursing staff of the unique and complex needs of children undergoing chronic treatment. As part of the overall treatment, nurses must broaden their knowledge of medical advancements in numerous areas: Increased knowledge in the area of child growth and development and unique formulas and "supplements".
