plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. photoautotrophic and photomixotrophic systems could diminish these problems. the purpose of this study was to increase the chlorophyll...

Background The 7S vicilin-like seed storage globulins represent an important class of food allergens. In many plants, the 7S globulins are synthesized as a precursor polypeptide, which undergoes post-translational proteolysis to remove a portion of the N-terminus to produce the mature protein sequence. However, the fate of the cleaved N-terminal region is largely unknown. We have identified and...

The aim of this study was to determine the level of heavy metals such as copper, iron, manganese, zinc, lead, nickel, cadmium and chromium concentrated in Juglans regia bark and leaf samples from different localities in Artvin, Turkey. Analysis of the heavy metals Cu, Fe, Mn, Zn, Pb, Ni, Cd and Cr in samples was carried out by inductively coupled plasma optical emission spectroscopy (ICP-OES; P...

We bring to the lab the theoretical result of Robinson (1985, RAND Journal of Economics 16: 141 145) that collusion is incentive compatible in the English auction (EN) and not in the firstprice sealed-bid auction (FP) in the case of one-shot interaction. Our data partly confirm Robinson’s prediction: in FP all cartels break down, but a majority of cartels breaks down in EN as well. However, mor...

background: diabetes is considered as one of the most common chronic disease. studies show that diabetes decreases the activity of antioxidant enzymes. the purpose of this study was to examine the effect of the alcoholic extract of juglans regia leave on brain antioxidant enzymes in streptozotocin-induced diabetic rats. materials and methods: in this study, adult male wistar rats (n=40, weight ...
