Melanocytes originate from a small number of precursors localized either side of the dorsal midline. The tyrosine kinase receptor Kit and its ligand Mgf (Steel Factor) are essential for melanoblast survival and proliferation during their migration from the neural crest. Inappropriate Kit expression in the dermatome and dermis of patch and rump-white mouse mutants apparently sequester Mgf, inhib...
The zinc element (Zn) is one of the micronutrients and an essential element of the body which has some deleterious and irreparable effects on growth in case of lack it. Thus, we aimed to assess IGF-1 in goldfish with Zn deficiency and to investigate the effect of Zn supplementation on these parameters. Goldfish (Carassius auratus) juvenile (3.5 g) were fed purified diets based on casein as ...
In this paper we study a particular Painlevé V (denoted PV ) that arises from Multi-InputMulti-Output (MIMO) wireless communication systems. Such a PV appears through its intimate relation with the Hankel determinant that describes the moment generating function (MGF) of the Shannon capacity. This originates through the multiplication of the Laguerre weight or the Gamma density xαe−x, x > 0, fo...
Mechanical induction of growth factor synthesis may mediate adaptive responses of smooth muscle cells (SMC) to increases in physical load. We previously demonstrated that cyclic mechanical stretch induces expression of the SMC, fibroblast, and epithelial cell mitogen heparin-binding epidermal growth factor-like growth factor (HB-EGF) in bladder SMC, an observation that suggests that this growth...
OBJECTIVE Vein grafts in a coronary bypass or a hemodialysis access often develop obliterative growth of the neointima. We previously reported that the mechanical stretch-activated insulin-like growth factor-1 receptor (IGF-1/IGF-1R) pathway plays an important role in this remodeling. However, the transcriptional mechanism(s) regulating IGF-1R expression and neointima formation have not been id...
In this paper, employing the polynomial approximation of the fading channel probability density function (pdf) for large average signal-to-noise ratio (ASNR), we derive general asymptotic moment generating function (MGF) expressions of the GSC output signal-to-noise ratio (SNR) for generalized fading channels. Based on the MGF result, the asymptotic diversity and coding gains for GSC are derive...
purpose a metabolic abnormality such as obesity is a major obstacle in the maintenance of the human health system and causes various chronic diseases including type 2 diabetes, hypertension, cardiovascular diseases, as well as various cancers. this study was designed to summarize the recent scientific knowledge regarding the anti-obesity role of curcumin (diferuloylmethane), which is isolated f...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
Pd/MgO, Pd/MgF₂ and Pd/MgO-MgF₂ catalysts were investigated in the reaction of CCl₄ hydrodechlorination. All the catalysts deactivated in time on stream, but the degree of deactivation varied from catalyst to catalyst. The MgF₂-supported palladium with relatively large metal particles appeared the best catalyst, characterized by good activity and selectivity to C₂-C₅ hydrocarbons. Investigation...
