Water stress and remobilization of dry matter and nitrogen in wheat and barley genotypes / by Zeinolabedin Tahmasebi Sarvestani.
… and nitrogen (N) in the grain and also their remobilization from the shoot to the grain. Water stress during grain filling was found to reduce DM and N accumulation and also to increase N concentration in both wheat and barley grain.

Development of a stem cell-based therapy for the recovery of skeletal muscle mass following immobilization
… to 1) determine the impact of immobilization and remobilization on pericyte quantity and function, and 2) determine the ability for exogenously administered pericytes to improve recovery following disuse. Utilizing a unilateral hindlimb immobilization model that results in specific atrophy of the …

Study of nitrogen limitation and seed nitrogen sources for historical and modern genotypes in soybean
… plus soil mineral N, is then fulfilled by the remobilization of N from vegetative organs during the seed filling period. An early remobilization process reduces the photosynthetic activity (leaves) and can limit seed yield. The objectives of this project were to: i) study yield improvements and …

Geology and mineralization in the vicinity of the Morning Star precious-metal deposit of the Ivanpah Mountains, San Bernardino County, California
… electrum and Ag+Au-sulfides indicate Au and Ag remobilization was isochemical in the lower portions of the deposit, while remobilization at upper levels of the deposit resulted in gold enrichment. Hydrothermal fluids (H₂O-CO₂-6 wt.% NaCl), that were driven by Late Cretaceous igneous activity, …

Geochemical Conditions Affecting Uranium(VI) Fate And Transport In Soil And Groundwater In The Presence Of Phosphate
… the effect of transport on U(VI) uptake and remobilization mechanisms and rate was examined. Continuous-flow stirred tank reactor: CFSTR) experiments at pH 4 were conducted under conditions supersaturated and undersaturated with respect to chernikovite and analyzed using a combination of …

Klinische Studien über die Immobilisation von Mantelpavianen (Papio hamadryas) unter Verwendung der "Hellabrunner Mischung" und über den postnarkotischen Einfluss von Atipamezol und Yohimbin im Vergleich zu Etilefrin als Aufwachbeschleuniger
… yielded no substantial acceleration of remobilization. The same side effects were observed after administering atipamezole. Similar to atipamezole, etilefrine also shortened the waking up phase significantly, but to a lesser extent than atipamezole. In contrast to atipamezole and …

Discovery of novel regulators and genes in nitrogen utilization pathways in maize
… the gene regulatory systems that modulate N remobilization. Advancements in sequencing and computational analysis have led to systems-level understanding of gene expression in the model plant Arabidopsis. These improvements can be applied in maize using transcriptional profiling and …

Optimization of a pericyte therapy to improve muscle recovery following hindlimb immobilization
… were excised for analysis after 2 weeks of remobilization and the extent of recovery was assessed. To characterize Tbx18+ cells, 5-month-old, Tbx18CreERT2:Ai9 mice (n=4) were injected with tamoxifen, and tdTomato expressing cells from the TA muscle were assessed for CD146 and NG2 using …

The biogeochemistry of 210Pb and 210Po in fresh waters and sediments
… water interface. Anoxic conditions caused remobilization of reduced iron, which reprecipitated at the oxycline and returned to the bottom via settling. 210Pb followed the same pattern except that, at the interface, it was scavenged rather than precipitated. Below the zone of precipitation, …
