“…Plasma GH is detectable after embryonic day 16 and most of somatotrophs respond to GHRH and somatostatin (Porter et al, 1995;Dean et al, 1997;Piper and Porter, 1997). TRH-secreting cells appear at embryonic day 5 (Thommes et al, 1983). Both TRH and somatostatin are also detectable by radioimmunoassay in thyrotrophs at embryonic day 14 (Harvey et al, 1979).…”

The somatotropic axis plays a key role in proliferation and differentiation of avian organs during both pre-and posthatching periods. This review discusses the complexity of regulation of the endocrine system for chicken development and growth by growth hormone (GH), insulin-like growth factor (IGF), and IGF binding protein (IGFBP). In addition, the thyrotropic axis, including thyrotropin-releasing hormone (TRH) and thyroid hormones (T 4 and T 3 ), is also involved in the GH-secreting pattern. In mammals, IGF-I and -II are always sequestered in a 150 kDa non-covalent ternary complex. This complex consists of one molecule each of IGF-I or IGF-II, IGFBP-3 or IGFBP-5 and an acid labile subunit (ALS). Chick ALS is identified in different strains for the first time, and further investigation of the expression of ALS on developmental stage and ALS effect on IGF bioavailability may be addressed in the future.

“…If the size of the MNS were small (<50 nm), the SPR has mainly near-field effects and causes the electromagnetic field to concentrate in the vicinity of the MNS. But if the size of these nanostructures were larger (>50 nm), the SPR is mostly of the far-field scattering type and the plasmonic structure acts as a back or forward scatterer 29 . In 2015, Carretero-Palacios et al analyzed the effect of the size and concentration of Au nanoparticles (NPs) embedded within the perovskite film on its absorption and have demonstrated that in such a configuration, the absorption is maximized when near-field and far-field effects of SPR are balanced 30 .…”

In this paper, a nanostructured perovskite solar cell (PSC) on a textured silicon substrate is examined, and its performance is analyzed. First, its configuration and the simulated unit cell are discussed, and its fabrication method is explained. In this proposed structure, poly-dimethylsiloxane (PDMS) is used instead of glass. It is shown that the use of PDMS dramatically reduces the reflection from the cell surface. Furthermore, the light absorption is found to be greatly increased due to the light trapping and plasmonic enhancement of the electric field in the active layer. Then, three different structures, are compared with the main proposed structure in terms of absorption, considering the imperfect fabrication conditions and the characteristics of the built PSC. The findings show that in the worst fabrication conditions considered structure (FCCS), short-circuit current density (Jsc) is 22.28 mA/cm2, which is 27% higher than that of the planar structure with a value of 17.51 mA/cm2. As a result, the efficiencies of these FCCSs are significant as well. In the main proposed structure, the power conversion efficiency (PCE) is observed to be improved by 32%, from 13.86% for the planar structure to 18.29%.
