  The photocleaving properties of 1 were studied by performing ΦX174 photocleavage assays. Light irradiation of the mixtures of increasing amounts of 1 with supercoiled DNA caused>90% supercoiled form relaxation and approximately 5% of linearization for the higher concentrations of 1 (1:10bp and 1:2bp

  2020-01-25

  

  Transcription can also be impaired by lesions in the template DNA strand, which may lead to stalling of RNA polymerase (RNAP) or to transcriptional mutagenesis, thus producing mutant RNAs and proteins [[3], [4], [5], [6], [7]]. At the same time, RNAP can act as a sensor for DNA lesions, by attractin

  In the belief that DNA-based nanosensors and DNA microarrays should be easier to operate, faster, more accurate and more economically viable than PCR-based techniques, an electrochemical DNA biosensor was designed for detection of G. boninense[9], [10]. This was developed based on a gold electrode m

  A recent analysis of 2721 urine samples collected from 245 men and 408 women across the US general population between 2005 and 2010 showed that MP, PP and BuP were measurable in 99.9%, 98.3% and 73.6% of samples from women and 99.3%, 90.2% and 35.9% of samples from men, respectively (Smith et al., 2

  Introduction Breast cancer is the most common malignant tumor in women and the second leading cause of female death [1]. In recent years, with the improvement of early detection and the emergence of new treatment methods, the mortality rate of breast cancer has been greatly reduced. However, the

  The importance of AAE3 in enhancing the survival of plants and yeast when confronted with certain environmental stresses has been documented in recent reports. In response to biotic stress such as oxalate-secreting micro-organisms, AAE3 was found to reduce the inhibitory growth effects of the secret

  The N&B method has the overall advantage that it is not restricted to certain dyes specific for energy transfer [55], and is also able to detect higher order receptor A 779 on the focal point in living cells. Conclusion The N&B method has shown to be a powerful tool to locate and quantify the a

  While showing that deletion of EP1 maintains femur bone volume fraction and trabecular bone parameters during aging, perhaps more importantly we have also demonstrated that increased initial BV/TV in EP1 is protective against OVX-induced bone loss. That is, while mice lose an approximately equal pe

  We should also note that oxygen pressure of Krebs solution bubbled with 95% O2+5% CO2 as we used in our study is reported to around 400 mmHg in several studies [48], [49], which is higher than normal arterial O2 pressure (80–100 mmHg). Although superoxide generation at elevated O2 tensions are note

  Introduction Although not fully understood, the molecular toxicology of sulfur mustard (bis(2-chloroethyl)sulfide, SM; CAS–Nr. 505-60-2), an alkylating warfare agent, has been attributed to DNA alkylation [1], [2], [3]. The same principle holds true for other alkylating compounds such as nitrogen
