Introduction: The purpose of this study was to investigate the ultrastructural change of the thymus under stress conditions created by diabetes accompanied by fasting, and also the effects of insulin therapy.
Methods: Forty-eight Sprague-Dawley type rats were used in this experiment. Type 1 diabetes symptoms were induced in 24 of the rats by the application of a single dose of intravenous streptozotocin in sodium citrate buffer through the tail vein. A single dose of sodium citrate buffer was given to rats to create a control group. Following the infusions, rats were divided into control, control and fasting, diabetes, diabetes and fasting, and insulin treatment groups. At the end of the experiment tissues from the thymus of the rats were extracted and examined using electron microscopy.
Results: Severe degeneration was observed in the prolonged fasting (stress) and diabetes groups without insulin treatment. Insulin treatment was found to mostly reverse this degeneration.
Conclusion: This study demonstrates that the thymus was affected ultrastructurally by diabetes and concomitant fasting, and insulin treatment can reverse these changes.

Type 1 diabetes mellitus (T1DM) is characterized by the progressive, autoimmune-mediated destruction of β cells. As such, restoring immunoregulation early in the disease course is sought to retain endogenous insulin production. Nevertheless, in the more than 100 years since the discovery of insulin, treatment of T1DM has focused primarily on hormone replacement and glucose monitoring.

Background: Nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) are associated with a multifactorial complicated aetiology that is often coexisting and has a strong and distinct connection with cardiovascular diseases (CVDs). In order to accomplish effective and appropriate therapeutic strategies, a deeper understanding of the bidirectional interaction between NAFLD patients, NAFLD patients with T2DM, and NAFLD patients with CVDs is required to control the concomitant rise in prevalence of these conditions worldwide. This article also aims to shed light on the epidemiology and mechanisms behind the relationship between T2DM, NAFLD and the related cardiovascular consequences.

Women with a history of gestational diabetes mellitus (GDM) significantly increase the risk of developing type 2 diabetes later in life. Although the increased glucose levels typically return to normal range after delivery for most GDM women, a significant proportion of GDM women develop impaired glucose tolerance or overt diabetes after delivery. Several factors associated with postpartum glucose abnormalities have been identified, yet the link between fasting glucose levels at diagnosis of GDM and postpartum glucose abnormalities remains unclear.
