The pandemic and the problem of compliance with safety measures: The case of Egypt.

Analysing data from a nationally representative sample of 3442 interviews conducted in Egypt in 2020, this study examines the influence of four sets of factors in predicting compliance with the advice of healthcare professionals to combat the spread of COVID-19: demographics, knowledge and values, fear of the disease and denial, and the pandemic as a foreign invasion. The findings show that a higher likelihood of compliance is linked to socioeconomic status, awareness of the pandemic, reliance on a plurality of information sources, adherence to liberal values, and fear of the disease, but being male, young, employed, religious, fatalistic, and in denial of the severity of the pandemic lower this likelihood - all consistent with the results reported in the literature. In addition, this study highlights the link between compliance and such attributes of nationalism as national identity, national pride, the perception of the pandemic as a national event, and the willingness to sacrifice one's human right to combat the spread of the disease.

Epigenetic alterations by methylation of RASSF1A and DAPK1 promoter sequences in mammary carcinoma detected in extracellular tumor DNA.

Novel strategies for early detection of breast cancer, the most common and second most lethal cancer in women, are urgently needed. Silencing tumor suppressor genes via DNA methylation has established hypermethylation as one of the most frequent molecular alterations that may initiate and drive many types of human neoplasia including breast cancer. Detecting such epigenetic changes in DNA derived not only from tumor tissue, but also from bodily fluids, may be a promising target for the molecular analysis of cancer.
