The genera Eriachaenium and Adenocaulon (Compositae) have distinct but complex histories and both have been placed in a number of tribes across the family. For the first time the two genera are included in a molecular study and the results show that they are best placed in the tribe Mutisieae s.s. and are the only genera in the re-instated subtribe Adenocaulinae. When described, this subtribe c...

Measuring the thermal conductivity of sub-surface buried substrates is significant practical interests. However, this remains challenging with traditional pump–probe spectroscopies due to their limited penetration depths. Here, we experimentally and numerically investigate TPD recently developed optical technique steady-state thermoreflectance (SSTR) explore its capability for measuring propert...

Somatostatin receptors (SSTR) are highly expressed in well-differentiated neuroendocrine tumors (NET). Octreotide, an SSTR agonist, has been used to suppress the production of vasoactive hormones and relieve symptoms of hormone hypersecretion with functional NETs. In a clinical trial, an empiric dose of octreotide treatment prolonged time to tumor progression in patients with small bowel neuroe...

A new species of aphid, belonging to the genus Macrosiphoniella Del Guercio, 1911, is described using three samples collected in Iran on Helichrysum armenium (Asteraceae, Inuleae) by the late Prof. G. Remaudière. Both apterous and alate viviparous females of the new taxon, Macrosiphoniella remaudiereisp. n., are described and compared to corresponding morphs of the closely allied Macrosiphoniel...

In this study, we investigated the relationship between affinity to somatostatin receptor subtype2 (SSTR(2)) and uptake of radioactivity from a group of radiolabeled somatostatin analogues in somatostatin receptor-rich tissues of rats. Organs with a high density of somatostin receptors (namely the adrenals and pancreas bearing mainly SSTR(2); this receptor subtype is also the most abundant in s...

(2017) on the evaluation of somatostatin receptor (SSTR) agonists and an antagonist for SSTRmediated imaging of breast cancer using positron emission tomography. In this study the authors com...

Somatostatin (SRIH) analogs can suppress the proliferation of human differentiated thyroid carcinoma cell lines that express SRIH receptors (SSTRs) demonstrated by radioligand binding analysis. Five distinct human SSTR subtypes (hSSTR1-5) that bind native SRIH exhibit diverse affinities to a wide range of SRIH analogs. Reverse transcriptase-PCR amplification of ribonucleic acids (RNAs) obtained...
