This work uses a combination of simulations performed via numerical models and field observations studied the attenuation deep-hole blasting stress waves evolution mechanism cracks in jointed rock mass. First, we conclude that larger joint angle is, is transmission coefficient smaller fractal dimension. Second, time difference between peak maximum principal on both sides hole horizontal directi...
Although the pro-inflammatory and pro-fibrotic actions of aldosterone on the vasculature have been reported, the effects and molecular mechanisms of aldosterone on endothelial function are yet to be determined. We investigated how aldosterone regulates endothelial nitric oxide synthase (eNOS) function in human umbilical vein endothelial cells (HUVECs). HUVECs were incubated for 16 hrs with 10(-...
The DNA backbone is often considered a track that allows long-range sliding of DNA repair enzymes in their search for rare damage sites in DNA. A proposed exemplar of DNA sliding is human 8-oxoguanine ((o)G) DNA glycosylase 1 (hOGG1), which repairs mutagenic (o)G lesions in DNA. Here we use our high-resolution molecular clock method to show that macroscopic 1D DNA sliding of hOGG1 occurs by mic...
The xeroderma pigmentosum C (XPC) complex initiates nucleotide excision repair by recognizing DNA lesions before recruiting downstream factors. How XPC detects structurally diverse lesions embedded within normal DNA is unknown. Here we present a crystal structure that captures the yeast XPC orthologue (Rad4) on a single register of undamaged DNA. The structure shows that a disulphide-tethered R...
