Diurnal variations in nitrate reductase (NR) activity and nitrogen metabolites were examined in wild-type Nicotiana plumbaginifolia and transformants with various degrees of NR deregulation. In the C1 line, NR was only deregulated at the transcriptional level by placing the NR gene under the control of the cauliflower mosaic virus 35S RNA promoter. In the Del8 and S521D lines, NR was additional...

Fetal intrauterine growth restriction (IUGR) is known to negatively affect offspring health postnatally. This study evaluated the impacts of early gestational undernutrition followed by realimentation on bovine fetal and placental growth. Thirty multiparous beef cows bred to a single sire and gestating female fetuses were fed to meet NRC recommendations (control; n = 15) or fed below NRC recomm...

In this study, the adsorption of neutral red (NR) on the spent ground coffee (SGC) was examined. The effect of various parameters such as pH and adsorbent dose on the removal of NR was investigated. The removal ratios of NR (25 and 40 mg/L) on SGC after 2 h were 95.6 and 90.2%, respectively. The removal ratio of NR is increased by increasing the pH value. Equilibrium data fitted very well in a ...

Two series of ligand precursors [2-OH-3-(CH(2)NR(2))-5-MeC(6)H(2)](2)CH(2) (1: NR(2) = NMe(2); 2: NR(2) = N(CH(2))(4); 3: NR(2) = N(CH(2))(5); 4: NR(2) = N(Me)Ph) and [2-OH-3-(CH=NR)-5-MeC(6)H(2)](2)CH(2) (10: R = 2,6-Pr(2)(i)C(6)H(3); 11: R = p-MeC(6)H(4); 12: R = p-ClC(6)H(4); 13: R = p-MeOC(6)H(4); 14: R = Bu(t)) were prepared. These compounds reacted with AlMe(3) to afford corresponding din...

We present an indexing scheme that is capable of answering a broad range of complex top-k queries that contain a scalar product between two vectors when one of the vectors is present in the database, while the other one arrives at query time. Specifically we provide indexing facilities for the top-k closest points below (above) a hyperplane and the top-k farthest points below (above) a hyperpla...

Experiments were conducted with segments of corn roots to investigate whether nitrate reductase (NR) is compartmentalized in particular groups of cells that collectively form the root symplastic pathway. A microsurgical technique was used to separate cells of the epidermis, of the cortex, and of the stele. The presence of NR was determined using in vitro and enzyme-linked immunosorbent assays. ...
