For the last several years, a number of researchers have been interested in the various problems which arise when modelling aggregate-type data [1st SDBM], [2nd SDBM], [3rd SSDBM], [Rafanelli 89]. Since aggregate data is often derived by applying statistical aggregation (e.g. SUM, COUNT) and statistical analysis functions over micro-data [Wong 84] the aggregate data bases are also called "stati...

known about the individual components of pest management applied to the diamondback moth, Plutella xylostella, in the Philippines is presented. This includes aspects relating to the pest, the agroecosystem, the plant, and preventive and curative control measures. Some successes have been obtained with a few of the components but many have not been tried in the field nor have there been sustaine...

Poly-L-lysine (PLL) is commonly used as an adhibiting agent due to its good viscosity, and demineralized bone matrix (DBM) is a common enriched matrix for selective cell retention technology. Therefore, the aim of this study was to use PLL to coat the surface and interspaces of DBM to form a novel type of enriched matrix [DBM coated with PLL (PLL-DBM)], in order to effectively improve the enric...

The use of a composite graft of bovine trabecular demineralized bone matrix (DBM) and perichondrium has been found a reliable method for in vivo generation of cartilage. In the present study, the mechanism whereby this commercially available matrix increases cartilage formation was investigated. First, the time course of cartilage formation in vivo, in the combined implant of perichondrium and ...

BACKGROUND Demineralized bone matrix (DBM) is used for bone healing due to its osteoinductivity, but it requires a carrier for clinical application. Here, we report the effects on the osteoinductivity of DBM by use of a poloxamer 407-based hydrogel as the carrier, compared to sterile water. METHODS DBM-W and DBM-H represent 27 wt% of DBM with sterile water and DBM with a poloxamer 407-based h...

The luminescence enhancement effect of different kinds and contents of rare earth complexe (RE(DBM)3Phen, RE = Dy, La, Gd, Sm, Y; DBM = dibenzoylmethane; Phen = 1,10-phenanthroline) sensitized Eu(DBM)3Phen doped in poly(methyl methacrylate) (PMMA) matrix was investigated using the combinatorial method. The efficiency of the luminescence enhancement increases with a decrease in the weight percen...

Demineralized bone matrix (DBM) is widely used for bone regeneration. Since DBM is prepared in powder form its handling properties are not optimal and limit the clinical use of this material. Various synthetic and biological carriers have been used to enhance the DBM handling. In this study we evaluated the effect of gamma irradiation on the physical-chemical properties of Pluronic and on bone ...

Hydroxyapatite (HA) is an osteoconductive material used as a bone graft extender and demineralized bone matrix (DBM) has been used as a source of osteoinductive factors. A combination of DBM and HA is expected to create a composite with both osteoconductive and osteoinductive properties. This study examined the effect of a combination of DBM and HA on osteogenesis both in vitro and in vivo usin...

A population of the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae) (DBM), was detected in 1999 on sugar snap peas (Pisum sativum) in the export vegetable growing area south of Lake Naivasha in the Rift Valley Province of Kenya. The performance of this new pea strain (DBM-P) was compared with the normal crucifer strain (DBM-C) in laboratory studies. DBM-P survived equally ...
