A case report: Acute abdominal pain caused by a mesenteric cyst in a 20 years old female patient.

Mesenteric cysts are documented as rare intra-abdominal benign tumors, whose etiology and classification controversy still exists. They are considered the rarest variety between the abdominal cysts and both its low incidence and the mistaken belief that was a trivial process without apparent symptoms, had contributed to their scarce knowledge. This study aimed to present a mesenteric cyst case with focal acute inflammation and four lymph nodes with follicular lymphoid hyperplasia.

Defective lysosomal proteolysis and axonal transport are early pathogenic events that worsen with age leading to increased APP metabolism and synaptic Abeta in transgenic APP/PS1 hippocampus.

Background: Axonal pathology might constitute one of the earliest manifestations of Alzheimer disease. Axonal dystrophies were observed in Alzheimer's patients and transgenic models at early ages. These axonal dystrophies could reflect the disruption of axonal transport and the accumulation of multiple vesicles at local points.
