Article Synopsis
- Pteronotus personatus is an insectivore bat with a high-protein diet, while Anoura geoffroyi is a nectarivore bat that consumes sugars like sucrose, glucose, and fructose.
- The study aimed to compare the morphology of the endocrine pancreas in these two bat species using histological, stereological, and immunohistochemical techniques.
- Results showed significant differences in pancreatic islet size, total number of islets, volume density, and distribution of α and β cells, indicating that their differing diets impact pancreatic structure and function.
Objective: Erythropoietin used to correct anaemia in chronic kidney disease (CKD) has been shown to increase blood pressure (BP) in CKD patients and experimental animals. Endothelin (ET)-1 expression is increased in CKD animals and patients, and enhanced by erythropoietin. Erythropoietin-induced BP rise was blunted by ETA receptor blockers.

Article Synopsis
- Diphylla ecaudata, a vampire bat that primarily feeds on bird blood, has significant dietary adaptations affecting its pancreatic structure.
- This study examined the pancreas of D. ecaudata and found a total of 23,900 pancreatic islets with varying sizes and distinct distributions of hormone-producing cells (insulin, glucagon, somatostatin).
- The pancreas shows unique islet characteristics compared to other mammals, indicating specialized endocrine functions adapted to its hematophagous diet.
