With aging and cancer there is increased expression or activity of matrix metalloproteinases (MMPs) that degrade and remodel the structural extracellular matrix (ECM). In addition, exposure of skin to ultraviolet (UV) radiation (photoaging) leads to loss of cell viability, membrane damage, and deposition of excessive elastotic material. Lutein has(More)
In skin aging there is deterioration of the extracellular matrix's collagen and elastin fibers, from its reduced biosynthesis and increased degradation by elastase and matrixmetalloproteinases (MMPs). Xanthohumol is a flavonoid isolated from the hop plant Humulus lupulus L., with anti-microbial, antioxidant, anti-inflammatory, and anti-carcinogenic(More)
Further immunocytochemical analysis of the neuroblasts with SRIF-like immunoreactivity (ir) was carried out on the chick embryo midbrain tegmentum. 5 or 100 microns mesencephalon sections were obtained from 60 White Leghorn chick embryos at stages (E = Embryonic days) ranging from E4 1/2 to E18 and incubated with rabbit polyclonal antibodies against(More)
With the aim of investigating some factors and mechanisms of the chicken brain development, the same thick sections of brain stems from twelve E13-to-E21-aged chick embryos were sequentially tested with a rabbit anti-Somatostatin antiserum, using a PAP-DAB technique, and with anti-tyrosine hydroxylase (-TH) monoclonal antibodies, using an indirect(More)
In Salmo gairdneri Richardson trouts, a comparison was made between macrophages (MO) derived from head kidney and peripheral blood monocytes. Morphologically and cytochemically no differences were observed between these two types of mononucleated cells. On the other hand, in parallel studies the ability of trout erythrocytes to engulf Candida albicans (CA)(More)
Further immunocytochemical analysis of the neuroblasts with SRIF-like immunoreactivity (ir) was carried out on the chick embryo medulla and pons. 5 or 100 microns rombencephalon sections were obtained from 60 White Leghorn chick embryos at stages (E = Embryonic days) ranging from E4 1/2 to E18 and incubated with rabbit polyclonal antibodies against(More)
The present study was conducted to determine the potential effect of the dietary intake of fenugreek (Trigonella foenum graecum) seeds alone or in combination with Bacillus licheniformis, Lactobacillus plantarum or B. subtilis on gilthead seabream quality and antioxidant response after 2 and 3 weeks of experimental feeding. The results showed that the(More)
