Impaired renal function in diabetic chimpanzees (Pan troglodytes)

Experimental and Molecular Pathology
I Y Rosenblum, F Coulston


Studies were conducted to assess the renal functional state in two recently discovered diabetic chimpanzees. Both were nonobese, adult female animals with the non-insulin-dependent form of impaired glucose tolerance, analogous to the Type II or nonobese, maturity-onset diabetes of humans. Both animals displayed moderate-to-heavy proteinuria and glycosuria in response to intravenous administration of glucose or tolbutamide. Chimpanzee number 333, but not number 1037, had fasting proteinuria and chronic hypertension. Renal function studies, using the inulin clearance method, demonstrated significantly decreased glomerular filtration rates and elevated rates of sodium excretion for both animals. The rate of chloride excretion was also elevated in animal number 1037, but potassium excretion was apparently unaffected in both animals. Abnormal serum biochemical parameters demonstrated for chimpanzee number 333 included elevations in calcium, magnesium, creatinine, urea nitrogen, and uric acid; animal number 1037 had only an elevated serum creatinine. Results are consistent with the occurrence of renal disease similar to the nephropathy that develops in human diabetics. The difference in severity of renal impairment in the two chimpan...Continue Reading

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.


Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

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.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

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.

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.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
