Tranexamic dosing for major joint arthroplasty in adult patients with chronic kidney disease: A pharmacokinetic study and new dosing regimen.

Background: Tranexamic acid is an anti-fibrinolytic agent routinely used during hip and knee joint replacement surgery to minimize bleeding. Chronic kidney disease is a common chronic health problem seen among adults requiring major arthroplasty surgery. Tranexamic acid is renally cleared and may accumulate in chronic kidney disease.

Insights into epithelial-mesenchymal transition from cystic fibrosis rat models.

Background: Molecular pathways contributing to Cystic Fibrosis pathogenesis remain poorly understood. Epithelial-mesenchymal transition (EMT) has been recently observed in CF lungs and certain CFTR mutation classes may be more susceptible than others. No investigations of EMT processes in CF animal models have been reported.

Lentiviral vector gene therapy and CFTR modulators show comparable effectiveness in cystic fibrosis rat airway models.

Mutation-agnostic treatments such as airway gene therapy have the potential to treat any individual with cystic fibrosis (CF), irrespective of their CF transmembrane conductance regulator (CFTR) gene variants. The aim of this study was to employ two CF rat models, Phe508del and CFTR knockout (KO), to assess the comparative effectiveness of CFTR modulators and lentiviral (LV) vector-mediated gene therapy. Cells were isolated from the tracheas of rats and used to establish air-liquid interface (ALI) cultures.

The RHCE gene encodes the chicken blood system I.

Background: There are 13 known chicken blood systems, which were originally detected by agglutination of red blood cells by specific alloantisera. The genomic region or specific gene responsible has been identified for four of these systems (A, B, D and E). We determined the identity of the gene responsible for the chicken blood system I, using DNA from multiple birds with known chicken I blood system serology, 600K and 54K single nucleotide polymorphism (SNP) data, and lowpass sequence information.
