Heterotopic pancreas of the gallbladder: A case report of a rare and commonly incidental finding.

Heterotopic pancreas (HP) refers to the presence of ectopic pancreatic tissue located outside of the normal pancreatic location without anatomical or vascular continuity with the pancreas. HP within the gallbladder (HPGB) was first described by Otschkin in 1916. It remains an exceedingly rare pathology with few reported cases.

While the number of studies investigating Achilles tendon pathologies has grown exponentially, more research is needed to gain a better understanding of the complex relation between its hierarchical structure, mechanical response, and failure. At the microscale, collagen fibers are, with some degree of dispersion, primarily aligned along the principal loading direction. However, during tension, rearrangements and reorientations of these fibers are believed to occur.

Annular pancreas is a rare congenital anatomical anomaly, in which the pancreatic parenchyma surrounds the descending duodenum. Generally, annular pancreas is diagnosed on the basis of symptoms associated with complications of peptic ulcer, pancreatitis, cholelithiasis, and rarely, malignant tumors. Herein, we report an 84-year-old man for whom, during hospitalization for a urinary tract infection, pancreatic cystic lesions and an annular pancreas were noted incidentally on computed tomography.

Article Synopsis
- Intrauterine exposure to methamphetamine (METH) during pregnancy negatively impacts testicular development in offspring, leading to apoptosis in spermatids.
- Research focused on proteins involved in sperm growth pathways, particularly TSSK and RIPK2, showing significant changes in their expression levels due to METH exposure.
- Findings indicated that METH exposure resulted in decreased TSSK expression, increased RIPK2 expression, thinner germ layers, more inflammatory cells, and a reduction in the thickness of seminiferous tubules in rat testes.
