Abstract

We studied the possible role of the diseased host pancreas and site of venous graft drainage in the development of hyperglucagonemia after pancreas transplantation, to identify the crucial steps of the technique capable of eliminating hyperglucagonemia and its possible diabetogenic effect. Therefore, we compared 4 groups of inbred rats: (1) heterotopic pancreas transplantation with either systemic (n = 9); or (2) portal (n = 5) venous drainage after prior induction of diabetes with streptozotocin; (3) orthotopic pancreaticoduodenal transplantation with portal venous drainage after prior pancreaticoduodenectomy (n = 7), and (4) sham-operation (Sham; n = 10). The postoperative period was 6 months. Only heterotopic transplantation with systemic venous drainage and loss of glucagon's first pass hepatic extraction, resulted in arterial hyperglucagonemia, whereas the arterial plasma insulin level was only slightly higher in comparison with the other groups. After either type of heterotopic transplantation the glucagon content of host pancreata remained unchanged, whereas the insulin content was approximately 5% of that in the pancreas of Sham rats. The insulin and glucagon contents of all grafts were similar to those of the control p...Continue Reading

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.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Epigenetic Memory

Epigenetic memory refers to the heritable genetic changes that are not explained by the DNA sequence. Find the latest research on epigenetic memory here.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Femoral Neoplasms are bone tumors that arise in the femur. Discover the latest research on femoral neoplasms here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
