DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Scientists find gene signature for poor response to standard therapy in rare uterine cancer

Women who don't survive a rare and aggressive uterine cancer called uterine serous carcinoma, have high expression of a group of 73 genes, a score scientists say can help identify these women and improve their outcome.

Immunity to coronavirus infection may help stem the pandemic

The raging coronavirus pandemic is causing immense fear and uncertainty across the world. One of the most distressing aspects of COVID-19 disease is the seemingly large number of unknowns. These include the burning question of immunity. Does a person who was sick with the COVID-19 and then recovered or was infected without symptoms, have immunity against re-infection?

Hydroxychloroquine and azithromycin treatment in 80 COVID-19 patients: short-term outcomes

The COVID-19 pandemic is still spreading around the world and affecting nearly 2.4 million people, with over 164,000 dead so far. With neither vaccine nor proven therapeutic drug being available so far, the need of the hour is for effective treatment. Now, a new study reports the potential usefulness of a combination of hydroxychloroquine and azithromycin as a treatment in mild cases of COVID-19 infection and urges the need for further evaluation and widespread use if its findings are confirmed.
