In 24 patients (16 women, 8 men, mean age 60 years), who underwent abdominal operations and who had a uncomplicated postoperative course, a teflon-tube was inserted into the portal vein at the end of laparotomy and remained there for maximal 9 days. The mean values of the portal venous pressure as well as of the portal-central venous pressure gradient are unchanged during the period of all 9 days and are between 7,4 and 7,9 mmHg, between 5,6 and 6,9 mmHg respectively. The arterio-portal venous 0(2)-content difference shows in the mean no fluctuations and is about 2 Vol.%. On the first postoperative day the lactic and pyruvic acid concentrations in the artery and portal vein are moderately, but significantly elevated and decrease to normal values until day 7. - 9.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
