MRI Imaging Methods The MRI image is formed by reconstructing signals generated from the resonance of hydrogen nuclei in a magnetic field. Therefore, the concept used in MRI images is “signal,” rather than the “density” concept used in CT images. In MRI images, lesions are described using the term “abnormal signal focus.” Because the imaging … Read more
1. NPT is a general-purpose American standard tapered pipe thread with a thread angle of 60°. PT thread is a British standard tapered thread with a thread angle of 55°, commonly used for sealing. British pipe threads are fine threads; coarse threads have a larger thread depth, which severely reduces the strength of the external … Read more

DNA methylation is one of the earliest discovered forms of gene epigenetic modification. In eukaryotes, methylation occurs only at cytosine, where DNA methyltransferases (DNMTs) convert the 5′ end cytosine of CpG dinucleotides to 5′-methylcytosine. Numerous studies have shown that DNA methylation can induce changes in chromatin structure, DNA conformation, DNA stability, and the interaction patterns … Read more
