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...

Administration of ursodeoxycholic acid (UDCA) has been shown to decrease serum total and low density lipoprotein (LDL) cholesterol in hypercholesterolemic patients with primary biliary cirrhosis. Results of previous studies prompted us to postulate that the cholesterol-lowering effect of UDCA may be due, at least in part, to a direct increment in hepatic LDL receptor binding [Bouscarel et al., ...

The capacity for 1-kestose uptake into the vacuole of fructan storing Jerusalem artichoke tubers was investigated. 1-kestose serves both as building block for fructan initiation and as a fructose donor for chain elongation. Tonoplast vesicles were isolated from actively storing tubers, and their vesicles were capable of transporting sucrose in a manner indicative of a sucrose/H(+) antiport. Und...

An in vitro experiment was conducted to determine the effect of supplemental non-fiber carbohydrate(NFC) on the disappearance kinetics of cellulose (Ce) by mixed ruminal microorganisms. Non-supplementedor NFC supplemented cellulose (467 mg NFC/g cellulose as sucrose (CeSu) or starch (CeSt) or a 1:1 mixtureof sucrose + starch (CeSuSt)) were incubated for 24, 48, and 96 h at 39°C. After each incu...

Received for Publication July 27, 1984 INTRODUCTION The time and amount of nitrogen (N) uptake affects both root and extractable sucrose yield of sugarbeets (Beta Vulgaris L.). Either excessive or late N fertilizer applications and subsequent plant N uptake from applied•or residual N sources cause an increasing proportion of the photosynthate to be used for top growth at the expense of both roo...

Herein we report the possibility of using green and red emitting silica-coated cadmium selenide (CdSe) quantum dots (QDs) for remarkable stem and cancer cellular imaging, efficient cellular uptake and fluorescence imaging of semi and ultra-thin sections of tumor for in vivo tumor targeted imaging applications. The comparative studies of high contrast cellular imaging behaviours of the silica-co...

background   objective:   materials and methods   results   conclusion   key words:   . vitrification, viability, in vitro maturation, gvbd, oocyte, mouse : these results suggest that step-wise vitrification of gvbd oocytes as compared to single step vitrification was better in the rate of survival and in vitro maturation of oocytes. : all non-vitrified oocytes were viable after 24 hr; however,...
