In part 1 of our review on somatostatin (SST) receptor biology in neuroendocrine tumours, the somatostatin receptor (SSTR) as a G-protein coupled receptor (GPCR), and the anti-tumour effects of SST and SSTR post-signalling pathways, were reviewed. To recapitulate, SST is a peptide hormone which acts mainly as an inhibitor in many endocrine systems. SST has five receptor subtypes (SSTR1–5) with ...
Oviductal sperm storage tubules (SST), located at the uterovaginal junction, are the primary site of sperm storage in turkeys. Sperm reside within these storage sites and may be released via a dynamic interaction between sperm mobility and a fluid current generated by the SST epithelial cells. In this study, aquaporins 2, 3, and 9 (proteins that form water channels in the plasmalemma of a varie...
عوامل مختلفی بین سطح msl و geoid یک جدایی ایجاد می کنند که به آن توپوگرافی سطح دریا و به اختصار sst گفته می شود. یکی از روش های تعیین sst فن local response technique است. این فن از عکس العمل سطح دریا در برابر عوامل بیرونی مانند فشار جو، درجه حرارت و باد و غیره برای تعیین sst استفاده می کند. بدین صورت که ابتدا دریا به مثابه دستگاهی فیزیکی ، عوامل خارجی در نقش توابع ورودی دستگاه و جزر و مد دریا د...
Purpose. In the mouse model of oxygen-induced retinopathy (OIR), somatostatin-14 (SRIF) acting at the SRIF receptor subtype 2 (sst(2)) inhibits angiogenic responses to hypoxia through a downregulation of vascular endothelial growth factor. Information about where SRIF-sst(2) interactions take place is lacking, and downstream effectors mediating SRIF-sst(2) antiangiogenic actions are unknown. Me...
Locally produced growth hormone (GH) and IGF-I are key factors in the regulation of mammary gland (MG) development and may be important in breast cancer development/progression. Somatostatin (SST) and cortistatin (CORT) regulate GH/IGF-I axis at various levels, but their role in regulating GH/IGF-I in MGs remains unknown. Since obesity alters the expression of these systems in different tissues...
In recent years, the synchrosqueezing transform (SST) has gained popularity as a method for the analysis of signals that can be broken down into multiple components determined by instantaneous amplitudes and phases. One such version of SST, based on the short-time Fourier transform (STFT), enables the sharpening of instantaneous frequency (IF) information derived from the STFT, as well as the s...
