Effect of COVID-19 on Pregnancy and Neonate's Vital Parameters: A Systematic Review.

Background: COVID-19 is a new pandemic, which was declared by the World Health Organization in 2019 as a threat to public health. According to numerous reports, it can have negative consequences for pregnant women, labour, and neonates born to infected mothers. The aim of this paper was to gather the evidence and to present a summary of the results of studies concerning COVID-19 in pregnant women and their neonates.

Gel electrophoretic separation of proteins from cultured neuroendocrine tumor cell lines.

Neuroendocrine tumors (NET) often develop asymptomatically and are detected at a late stage. Currently, there exist certain markers of NET that occur only in the advanced stages of the disease. Still, there is need to develop markers specific of the early stage of cancer development.

Chemometric evaluation of urinary steroid hormone levels as potential biomarkers of neuroendocrine tumors.

Neuroendocrine tumors (NETs) are uncommon tumors which can secrete specific hormone products such as peptides, biogenic amines and hormones. So far, the diagnosis of NETs has been difficult because most NET markers are not specific for a given tumor and none of the NET markers can be used to fulfil the criteria of high specificity and high sensitivity for the screening procedure. However, by combining the measurements of different NET markers, they become highly sensitive and specific diagnostic tests.
