Nuclear factor Y (NF-Y) is a class of transcription factors (TFs) with various biological functions that exist in almost all eukaryotes. In plants, heterotrimers composed different NF-Y subunits are numerous and have can participate the regulation plant growth at stages. However, genes not been systematically analyzed chrysanthemum, only involving several members. this study, forty-six members ...

Nuclear Factor Y (NF-Y) is a heterotrimeric transcription factor that binds CCAAT elements. The NF-Y trimer is composed of a Histone Fold Domain (HFD) dimer (NF-YB/NF-YC) and NF-YA, which confers DNA sequence specificity. NF-YA shares a conserved domain with the CONSTANS, CONSTANS-LIKE, TOC1 (CCT) proteins. We show that CONSTANS (CO/B-BOX PROTEIN1 BBX1), a master flowering regulator, forms a tr...

in this research, the chloroform (chcl3) removal effectiveness of two water treatment systems including membrane technology and granular activated carbon (gac) adsorption were studied. two bench-scales were designed and set up: 1) nanofiltration (nf) spiral-wound modules and 2) gac adsorption column. chloroform was considered as trihalomethanes (thms) basic indicator compound. the inlet and out...

background: the close relationship between energy metabolism, nutritional state, and reproductive physiology suggests that nutritional and metabolic disorders can disrupt normal reproductive function and fertility. considering the importance of leptin and ghrelin effects in regulation of the hypothalamic-pituitary-gonadal axis, the objective of this study was to investigate the influence of obe...

background: it has been suggested that malfunction of immune system may cause testicular cancer. recently, our understanding of innate immune system has been expanded, by discovery of “toll- like receptors” (tlrs). some studies have shown that polymorphisms of tlr2 and 4 can effect on the risk of cancer. also, the role of tlrs 3and 9 have been shown in apoptosis of cancer cells and metastasis i...

objective(s):therapies with high levels of oxygen are commonly used in the management of critical care. however, prolonged exposure to hyperoxia can cause acute lung injury. although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (hali).   materials a...

The synthesis and subsequent modification of neurofilament (NF) polypeptides has been examined in pulse-chase experiments, using cultured chick spinal cord neurons. Fluorography of the [35S]methionine-labeled cytoskeletal proteins, after separation by two-dimensional gel electrophoresis, revealed that (a) the mid-size chicken NF protein, NF-M160, is synthesized as a smaller and more basic precu...
