Abstract

The effects of acid-base changes on cardiac output during diethyl ether anaesthesia were studied in 25 mongrel dogs prepared by surgically implanting a plastic encased non-ferrous core electromagnetic probe on the ascending aorta. The findings are: (1) Metabolic acidaemia produced only slight decrease in cardiac output but a more marked fall became evident with decreasing pH(2) Respiratory acidaemia led to a slight rise in cardiac output. (3) Respiratory alkalaemia decreased cardiac output. (4) Metabolic alkalaemia also produced a decline in cardiac output.

COVID-19

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 Array Analysis

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.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
