Objectives: The main endocrine cell types in pancreatic islets are alpha-, beta-, and delta-cells. Although these cell types have distinct roles in the regulation of glucose homeostasis, inadequate purification methods preclude the study of cell-type-specific effects. We aimed to develop a reliable approach that enables simultaneous sorting of live alpha-, beta-, and delta-cells from mouse islets for downstream analyses.Methods: We developed an antibody-...

Early diagnosis is crucial for thyroidectomy before metastasis. This case report aims to increase awareness of MEN2B signs and symptoms and the need for early referral and treatment.Case: A 10-year-old girl was referred for ultrasound imaging of a swollen submandibular g...
