Abstract Retroperitoneal abdominal pregnancy is exceptionally rare. An unusual retroperitoneal has a high risk of severe bleeding. Abdominal ultrasonography and whole computerized tomography scanning should be performed for the early diagnosis ectopic pregnancy. A case located very close to large blood vessels treated with resection presented. Many features were highlighted as providing further evidence in support main proposed embryo migration mechanism via lymphatic vessels.

Emerging evidence suggested widespread decreased gray matter volume (GMV) and tau hyperphosphorylation were associated with type 2 diabetes mellitus (T2DM). Insulin resistance is one of the mechanisms neuron degeneration in T2DM; it can decrease activity protein kinase B increase glycogen synthesis kinase-3β, thus promoting finally leading to neuronal degeneration. However, association between GMV serum phosphorylated at threonine 181 (P-tau-181) T2DM patients lacks neuroimaging evidence. We...
