Replication protein A (RPA) is a single-stranded DNA-binding protein identified as an essential factor for SV40 DNA replication in vitro. To understand the in vivo functions of RPA, we mutagenized the Saccharomyces cerevisiae RFA1 gene and identified 19 ultraviolet light (UV) irradiation- and methyl methane sulfonate (MMS)-sensitive mutants and 5 temperature-sensitive mutants. The UV- and MMS-s...
The anaphylactic release of histamine from perfused, chopped guinea pig lung is very sensitive to changes in the NaCl concentration of the containing medium, and it is ionic strength rather than particle concentration which is critical. Consequently, in studies with inhibitors care must be taken to avoid inadvertently increasing ionic strength and thereby misinterpreting the cause of the inhibi...
conclusions the he jump mat can be recommended in relation to the validity of constraints. in this study, only a part of the quality criteria were examined. for the final recommendation it is advised to examine the he jump mat on the other quality criteria (test-retest reliability, sensitivity change). background in the field of vertical jump diagnostics, force plates (fp) are the reference sta...
Arterial blood collected from sheep was analyzed for various amino acids to evaluate effects of dietary forage characteristics on adequacy of amino acid availability for protein synthesis. In three experiments with grass diets consumed Ž . ad libitum or in limited quantities by nearly mature wethers, differences in grass source and or quality generally did not Ž markedly affect arterial concent...
Marrow adipose tissue (MAT) accumulates in diverse clinical conditions but remains poorly understood. Here we show region-specific variation in MAT adipocyte development, regulation, size, lipid composition, gene expression and genetic determinants. Early MAT formation in mice is conserved, whereas later development is strain dependent. Proximal, but not distal tibial, MAT is lost with 21-day c...
Study Aims. Evaluate the quality and effectiveness of the medication-assisted therapy (MAT) pilot in Kazakhstan and review implementation context and related challenges. Methods. We performed a desk review of MAT policy and program documents and reviewed medical records at three MAT sites in Kazakhstan. MAT patients (n = 93) were interviewed to assess their perceptions of the program and its im...
HO endonuclease-induced double-strand breaks (DSBs) within a direct duplication of Escherichia coli lacZ genes are repaired either by gene conversion or by single-strand annealing (SSA), with > 80% being SSA. Previously it was demonstrated that the RAD52 gene is required for DSB-induced SSA. In the present study, the effects of other genes belonging to the RAD52 epistasis group were analyzed. W...
Efficient repair of DNA double-strand breaks (DSBs) requires the coordination of checkpoint signaling and enzymatic repair functions. To study these processes during gene conversion at a single chromosomal break, we monitored mating-type switching in Saccharomyces cerevisiae strains defective in the Rad1-Rad10-Slx4 complex. Rad1-Rad10 is a structure-specific endonuclease that removes 3' nonhomo...
