We have reported earlier some work on the grafting of vinyl monomers onto cellulose extracted from pine needles. The grafting was carried out both by radiation1,2 and by a chemical initiation method3,4. The optimum grafting conditions for a single monomer were used to co-graft it with other comonomers so as to improve upon the intrinsic properties of the cellulose backbone5,6. These graft copol...

A grafting robot based on cleft grafting method has been developed to improve efficiency of grafting solanaceae vegetables. This robot consists of four parts including a clamping manipulator and carrying, cutting, feeding mechanisms. These not only enable the robot to conveniently perform clamping, carrying, positioning, cutting, joining, and binding rootstock and scion, but also improve the gr...

Surgical treatment for diffusely diseased coronary arteries has been considered to be a relative contraindication for off pump coronary artery bypass (OPCAB) grafting. We report a case of off pump long-onlay-bypass grafting using the left internal mammary artery. To our knowledge, the long-onlay-patch grafting with OPCAB technique has not been previously described. Two sets of Octopus-3 tissue ...

Background: Penile foreskin is a readily available source of dermis, but it is not often used for skin grafting. Objective: To report the use of the preputial foreskin as donor for full thickness skin grafting. Methods: The preputial foreskin was used as donor for skin grafting in 42 Thai boys. Results: The size of the donor graft obtained varied from 15-50 cm2 depending on the patients’s weigh...

Most of the natural polysaccharides have been used as food and pharmaceutical excipients due to their biodegradability, biocompatibility, low cost and easy availability. Diverse approaches such as etherification, crosslinking and graft co-polymerization can be used for the chemical modification of natural polymers. Grafting process is a suitable method to add new properties to a natural polymer...

Decision tree grafting adds nodes to inferred decision trees. Previous research has demonstrated that appropriate grafting techniques can improve predictive accuracy across a wide cross-selection of domains. However, previous decision tree grafting systems are demonstrated to have a serious deeciency for some data sets containing missing values. This problem arises due to the method for handlin...

Decision tree grafting adds nodes to an existing decision tree with the objective of reducing prediction error. A new grafting algorithm is presented that considers one set of training data only for each leaf of the initial decision tree, the set of cases that fail at most one test on the path to the leaf. This new technique is demonstrated to retain the error reduction power of the original gr...

Introduction: Gold standard for alveolar cleft bone grafting is autogenous bone. Advantage of adding the growth factors to the bone is established, so adding PRF to the autogenous bone may have beneficial effects. Methods:  Platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. Results:  Autogenous bone in all (four cases...

This investigation indicates the ability to selectively graft glycidyl methacrylate (GMA) only from the external surface of regenerated cellulose (RC) ultrafiltration (UF) membranes using activator generated electron transfer (AGET) atom transfer radical polymerization (ATRP). This controlled polymerization resulted in epoxy functionalized polymer brush ends. Further reaction of the terminal ep...

BACKGROUND A 1987 American Society of Plastic and Reconstructive Surgeons position paper predicted that fat grafting would compromise breast cancer detection and should therefore be prohibited. However, there is no evidence that fat grafting to breasts is less safe than any other form of breast surgery. As discussions of fat grafting to the breast are surfacing all over the world, it is time to...
