Somatostatin receptor (sstr) scintigraphy for imaging and sstr analogs for treatment have been used for more than 20 y. An important improvement in recent years was the introduction of peptide receptor radionuclide therapy with radiolabeled sstr agonists, such as [(90)Y-DOTA(0),Tyr(3)]octreotide or [(177)Lu-DOTA(0),Tyr(3)]octreotide ((90)Y- or (177)Lu-DOTATOC, respectively) and [(177)Lu-DOTA(0),Tyr(3)]octreotate ((177)Lu-DOTATATE). PET/CT with (68)Ga-labeled sstr agonists, such as (68)Ga-DOTATOC, (68)Ga-DOTATATE, and [(68)Ga-DOTA,1-Nal(3)]octreotide ((68)Ga-DOTANOC), plays an important role in staging and restaging neuroendocrine tumors...

Chronic cerebral hypoperfusion (CCH) contributes to the Alzheimer's-like pathogenesis, but the relationship between CCH and the occurrence of Alzheimer's disease (AD) remains obscure. The aim is to elucidate the potential pathophysiological mechanism in the field of amyloid-beta (Aβ) pathology induced by CCH. A rat model of CCH has been developed with permanent bilateral occlusion of common carotid arteries (BCCAO). The cognitive function of rats was tested by the Morris water maze. The levels of Aβ (Aβ40 and Aβ42) and soluble amyloid precursor protein (sAPP: sAPPα and sAPPβ) were determined by enzyme linked immunosorbent assay...
