Effects of Long-term Storage of One-year-old Rootstocks in Snow Mound on the Sugar Contents of Storage Roots and White Spear Yield of Asparagus

Purpose.This study investigated the long-term resin-dentin bond strength of dentin biomodified by proanthocyanidin-rich (PA) agents.Materials and Methods.Forty molars had their coronal dentin exposed, etched, and treated for 10 minutes with 6.5% grape seed extract (GSE), 6.5% cocoa seed extract ethanol-water (CSE-ET), 6.5% cocoa seed extract acetone-water (CSE-AC), and distilled water (CO). Samples were restored either with One-Step Plus (OS) or Adper Single-Bond Plus (SB). Bond strength test was performed immediately or after 3, 6, and 12 months.Results.HigherμTBS were observed for GSE immediately (SB- 62.9 MPa; OS- 51.9 MPa) when compared to CSE-ET (SB- 56.95 MPa; OS- 60.28 MPa), CSE-AC (SB- 49.97 MPa; OS- 54.44 MPa), and CO (SB- 52.0 MPa; OS- 44.0 MPa) (P<0.05). CSE outcomes were adhesive system and solvent dependant. After 12 months storage SB results showed no difference among treatment types (GSE- 57.15 MPa; CSE/ET- 54.04 MPa; CSE/AC- 48.22 MPa; CO- 51.68 MPa;P=0.347),while OS results where treatment dependent (GSE- 42.62 MPa; CSE/ET- 44.06 MPa; CSE/AC- 41.30 MPa; CO- 36.85 MPa;P=0.036).Conclusions.GSE and CSE-ET agents provided enhanced immediate adhesion and stabilization to demineralized dentin after long-term storage, depending on adhesive system.

Term Storage

Bull's eye rot of pome fruits caused by Neofabraea spp. is characterized by infection occurring in the orchard throughout the growing season whereas rot lesions develop during long-term storage after harvest. Bull's eye rot was observed on pear fruit exposed to natural infection for any of six to nine sequential 1-to-2-week exposure periods during two growing seasons. Highest infection levels were associated with exposure closest to harvest. Over-tree irrigation and late harvest resulted in higher bull's eye rot incidence than under-tree irrigation and early or mid-season harvest. Fruit were inoculated prior to harvest with Neofabraea perennans to determine the effect of environmental factors on the development of bull's eye rot. The effect of temperature was inconsistent; disease was greatest at 10°C in one year of study but greatest at 30°C in the second year. Bull's eye rot developed independently of wetness durations longer than 0.5 h.

Term Storage

Hymenaea courbaril is an endangered species, promising to reforestation programs and mainly explored as a wood source. The available information concerning long-term storage methods, seed recalcitrance, parental, and substrate influence is scarce. This study focused on the seed behavior according to population origin and during one-year storage, also testing the efficiency of the low-temperature conservation. Variations between the uncertainty indexes were found to the studied populations after long-term storage. There was no significant loss of the germination potential in consequence of the prolonged storage period. Although, older seeds promoted gradually greater delayed germination. Germination speed, synchrony, and uncertainty indexes were substantially different between the -20° conservation and control. H. courbaril seeds are capable of long-term storage without losing their germination potential, indicating an orthodox behavior.

Investigations of latrine wastes in Botswana were undertaken to verify that sludge stored in a pit latrine chamber for at least one year does not constitute an unacceptable microbiological hazard on handling or reuse. Levels of faecal bacteria, Ascaris, Taenia, Schistosoma and human enteric viruses in sludges which had been stored for periods of more than one year were compared with levels in improperly stored sludges. In all cases, the importance of long term storage was confirmed. However, it is noted that substantial sociological and educational inputs are required if latrine users are to obtain the maximum health and economic benefits of latrine sanitation and sludge reuse, particularly in cultures where there is traditionally little interest in such practices.

Neutrophil Engraftment

Abstract Adequate viability after cryostorage is essential to allow engraftment of autologous haematopoietic progenitor cells (HPC). Information on the effect of prolonged cryopreservation on HPC viability in humans is limited although donations are routinely stored for over a year. Long-term storage is expensive and demonstration of clinical efficacy of HPC after long-term cryopreservation is important in order to justify the use of resources. Available reports describe only isolated cases in which old cells have been infused. We have conducted a retrospective survey of transplants using HPC stored >1 year within the National Blood Service in England. In total 75 patients received HPC that had been frozen for >1yr in NBS Laboratories. Patients had AML (21), NHL (21), myeloma (18), CML (5), Hodgkins disease (6) and other diseases (4). Fifty seven patients received PBSCs cryopreserved for >1 yr with median time in storage of 23 (12.1–65) months and median infused CD34 dose of 4.6 (1.2–85) ×106/kg. Neutrophil recovery to >0.5 × 109/l was 12 (4–49) days and platelets to > 20 × 109/l was 13 (3–43) days. Thirteen patients received bone marrow that had been cryopreserved for >1 year (median 32 (13–67) months) with infused TNC dose of 1.7 (0.91 – 3.64) × 108/kg. Time to neutrophils >0.5 × 109/l was 17 (12–95) days and platelets > 20 × 109/l 16 (12–66) days. A further 5 patients received a mixture of PBSCs and BM products all of which had been stored for > 1 year. Delayed neutrophil engraftment (neutrophils <0.5 × 109/l at 21 days) occurred in 2/55 PBSC transplants and 2/8 BM transplants. Delayed platelet engraftment (platelets <20 × 109/l at 28 days) occurred in 4/48 PBSC transplants and 4/8 BM transplants. In this survey, although the use of HPC cryopreserved for more than one year was infrequent, satisfactory engraftment was achieved in most patients. The rate of delayed engraftment was higher in BM as compared to PBSC transplants but numbers are too small for statistical analysis. In vitro viability assays were not available in this study but may help inform decisions on the use of cells stored for long periods.

Branched (B) and unbranched (UB) one-year-old `Bradford'/`OHFx97' trees were examined at intervals between preparation for bare root harvest and long term storage to determine the extent of mechanical bud damage caused by the various handling steps. After hand stripping of leaves, digging, transportation to the storage facility, and grading, and tying of bundles, there was a marked difference in the percentage of damaged buds between branched (26%) and unbranched (53%) trees. The B/UB live bud ratio before and after harvest was 1:0.45 and 1:0.26, respectively. This difference may have been due to a various morphological growth pattern which both types of trees had produced.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.
