Composites are being used extensively in several engineering applications. However, the efficiency of the joints used in joining composites and metals can be improved. To move towards a sustainable and environment friendly future, natural fibre composite material was used. Towards the above objective, research work was carried out for the assembly between a composite and aluminium. Three differ...

The role of glycoprotein (GP) IIb-IIIa complexes and of adhesive proteins in mediating platelet aggregation is now well defined. However, less is known of the changes that occur once aggregation has begun. We report immunogold staining of thin sections of platelets or platelet aggregates, embedded in Lowicryl K4M, after the use of polyclonal antibodies to GP IIb or GP IIIa, fibrinogen (Fg), von...

Epican is a heparan/chondroitin sulfate proteoglycan form of CD44 and is expressed on the surface of keratinocytes from the basal layer to the granular layer of the epidermis. To analyze the adhesive properties of epican apart from the influence of other adhesive molecules found on keratinocytes, mouse L cell fibroblasts were transfected with CD44Epican cDNA. The epican expressed on the surface...

Gicerin is a cell adhesion molecule in the immunoglobulin superfamily. This molecule has homophilic and heterophilic adhesive activities, binding to the neurite out-growth factor (NOF). We have previously reported that gicerin plays an important role in the development and regeneration as well as in the metastasis of tumors through its adhesive activities, mediating cell-cell and/or cell-extrac...

background and aims. nano-ionomer (ni) interacts with tooth structures superficially, and there is a concern about the enamel bonding ability of mild self-etch ketac primer. this study compared the effect of different adhesive procedures (self-etching and etch-and-rinse approach) on long-term marginal microleakage of nano-filled resin-modified glass-ionomer (ni) cervical restorations. materials...

debonding is a common occurrence in orthodontic treatment and a considerable number of orthodontists prefer to rebond the detached brackets because of economic issues. the aim of this study was to compare the microleakage beneath rebonded stainless steel brackets using two methods of adhesive removal namely sandblast and laser.sixty human premolar teeth were randomly divided into three groups. ...

Four children with an immunodeficiency involving the absence of leukocyte membrane glycoproteins reacting with anti-LFA-1 and OKM-1 monoclonal antibodies were unable to mediate adherence-dependent leukocyte functions. Even with normal Fc receptor function, their PMN-ADCC and MC-NKC were markedly deficient. Single cell analysis demonstrated deficient antibody-mediated PMN-target cell adherence. ...

Middle lobe torsion after right upper lobectomy is a rare but serious complication. Simple lobar shift may also lead to a bronchial plication, causing iterative pneumopathies. The preventive fixation of middle lobe to lower lobe is indicated to avoid these complications in case of complete major fissure. We performed this fixation, by using a resorbable anti-adhesive membrane, usually indicated...
