Somatostatin (SS) and dopamine (DA) receptors have been highlighted as two critical regulators in the negative control of hormonal secretion in a wide group of human endocrine tumors. Both families of receptors belong to the superfamily of G protein-coupled receptors and share a number of structural and functional characteristics. Because of the generally reported high expression of somatostati...
Diagnosis of cardiac sarcoidosis is often challenging. Whereas cardiac magnetic resonance imaging (CMR) and positron emission tomography/computed tomography (PET/CT) with 18F-fluorodeoxyglucose (FDG) are most commonly used to evaluate patients, PET/CT using radiolabeled somatostatin receptor (SSTR) ligands for visualization of inflammation might represent a more specific alternative. This study...
BACKGROUND & OBJECTIVES Chemotherapy with praziquantel remains the only control measure to Schistosoma mansoni infections to date. The neuropeptide hormone somatostatin gives relief from gastrointestinal disturbances, liverpathology, and reduces egg production in S. mansoni infected mice, suggesting an interaction of somatostatin with the parasite rather than with the host alone. Using antibodi...
Somatostatin (SST)b exerts diverse biological actions through a family of five cell surface SST receptors (SSTR) subtypes. These can be categorized into two subgroups, one consisting of SSTRs 2,3 and 5 and the other made up of SSTRs 1 and 4 on the basis of their ability or inability to bind octaand hexapeptide SST analogs [1, 2]. SST influences multiple second messenger systems including adenyl...
OBJECTIVE Somatostatin (SST) analogues are a key option in the management of a variety of conditions, including acromegaly. Tachyphylaxis to SST analogues is not documented in acromegaly. We describe such a phenomenon. DESIGN AND METHODS A 74-year-old female with acromegaly previously treated with (90)Y implant, external radiotherapy and thrice daily s.c. octreotide had stable GH levels of 19...
جنس های amblyocarpum fisch. & c. a. mey. و .carpesium l از جنس های کوچک تبار inuleae s. str می باشند. جنس amblyocarpumفقط دارای یک گونه به نام amblyocarpum inuloides و جنس نزدیک آن یعنی carpesium دارای دو گونه c. abrotanoides و c. cernuum در ایران می باشد. در این بررسی، این سه گونه از ایران مورد مطالعه آناتومی ساقه و دمگل آذین و اسکنینگ سطح دانه گرده قرار گرفتند. نتایج حاصله تأیید کننده کار...
