BACKGROUND Renal transplantation is recognised as being the optimal treatment modality for many patients with end stage renal disease. This analysis aimed to explore the equity of access to renal transplantation in the UK. METHODS Transplant activity and waiting list data were obtained from NHS Blood and Transplant, demographic and laboratory data were obtained from the UK Renal Registry. All...
Loblolly pine (Pinus taedu L.) seedling height, root collar diameter (RCD) and the specific activities of three sucrose metabolizing enzymes, namely, sucrose spthase (SS), acid invertase, and neutral invertase, were measured to assess seedling responses to transplant stress. Bare-root nursery-grown loblolly pine seedlings were lifted and transplanted immediately into nearby nursery beds in Febr...
Zinc (Zn) deficiency is one of the leading nutrient disorders in rice (Oryza sativa). Many studies have identified Zn-efficient rice genotypes, but causal mechanisms for Zn deficiency tolerance remain poorly understood. Here, we report a detailed study of the impact of Zn deficiency on crown root development of rice genotypes, differing in their tolerance to this stress. Zn deficiency delayed c...
We investigated the roles of specific subsets of donor APCs purified from bone marrow in donor T cell activation and graft-vs-leukemia (GvL) activity in murine models of hemopoietic stem cell transplantation. Lineage(-)CD11c(+) APC precursors were separated from donor bone marrow based on expression of CD11b. Transplanting lineage(-)CD11c(+)CD11b(-) APC (CD11b(-) APC) in combination with c-kit(...
Four semi-dwarf rices (Oryza sativa L.) differing in percentage of grain protein, grown in a flooded field receiving basal N fertilization, had a peak activity of root glutamate dehydrogenase 4 weeks after transplanting. A lower peak occurred during panicle formation 10 weeks after transplanting. The percentage of N of the active leaf blades was also highest 4 weeks after transplanting. The act...
Vegetable transplanting is an important and advantageous practice in vegetables production systems. In recent years, the development of vegetable tools has increased, as well interest for automatic robotic transplanters. However, at present, feeding machines often still performed by hand. This paper presents design, testing a needle gripper two-finger transplanting. Both grippers were self-desi...
The objective of this study was to review the research and development in semi-automatic vegetable transplanters. Discuss various transplanters on basis metering mechanism, power source, plant spacing, number rows, field capacity, efficiency, etc. On review, it is observed that transplanting rate, capacity efficiency better than handheld traditional method transplanting. It maintains row distan...
