Ethics related to traditional medicine

Ethics related to traditional medicine. It is very important for grant proposals, scientific integrity and patients' safety. Link relates to this topic:  https://t-lerksuthirat.blogspot.com/2021/05/note-musc-research-forum-new-normal.html

Note: The DNA damage response and cancer therapy_2012 Doi: 10.1038/nature10760 Future issues; Pharmacological targeting  Biochemical and genetic interactions between the various DNA repair pws -- not clearly understood Having small potent inhibitors which specifically inhibits particular pw facilitating the interplay between DNA repair pws. Cancer stem cells and tumor micro-environment Systemic knowledge in DNA damage and DDR in stem cells need to be explored Genomic scar Cancer being classified according to their underlying pattern of pathogenic mutations Sequence scare -- reflects bot mutagens which tumor has been exposed to and repair processes that have to operated to mitigate their impact Example; HRD Microsatellite instability Mismatch repair is defective Matching molecular signatures of DNA mutation and repair -- require functional biomarkers -- which identify DDR defect and facilitate in the selection of therapy Example -- RAD51 foci formation Requiring genotoxic stress followe

Chi-square

The Chi-square test is used to compare the differences between categorical data. My Note from Datacamp subscription - เหมือนกับว่าเรามีค่า observatory data มาแล้ว และมันจะคำนวนหาค่า expected data มาให้ โดยค่าที่เป็น expected data จะเป็นค่าที่ ค่า variable  This statistic that we've just formulated is called the chi-squared statistic. It captures the distance between a contingency table and the table you would expect if the variables were independent of one another. We found that the statistic for the relationship between party and natspac was one-point-three-three. If we calculate the statistic for the relationship with natarms, we get a much greater distance: eighteen-point-nine-seven. With this statistic in hand, you can return to the hypothesis test to answer the question of if either of these observed statistics: one-point-three-three or eighteen-point-nine-seven is so great as to lead you to reject the null hypothesis that these spending priorities are independent of political
