This article reviews the mechanisms of bacterial adhesion to biomaterial surfaces, the factors affecting the adhesion, the techniques used in estimating bacteria-material interactions and the models that have been developed in order to predict adhesion. The process of bacterial adhesion includes an initial physicochemical interaction phase and a late molecular and cellular one. It is a complica...

Platelet adhesion to collagens immobilized on plastic has been measured, with the following results. (1) Human, but not rabbit, platelets adhered readily to pepsin-extracted monomeric collagens in an Mg2(+)-dependent manner. (2) Rabbit platelets adhered to a monomeric collagen extracted without pepsin by a process that was cation-independent; human platelet adhesion to this collagen exhibited a...

OBJECTIVE Prophylactic trans-catheter arterial balloon occlusion (PTABO) before cesarean section of placenta previa totalis has been introduced to prevent massive hemorrhage. The purpose of this study is to evaluate the clinical usefulness of PTABO in cases of suspected placental adhesion and to examine antepartal risk factors and perinatal outcomes in women with placental adhesion. METHODS B...

The degree of meat adhesion to different kinds of plastic casings was examined in retort sterilized fish sausages. It was found that the plastic casings of great wettability such as polyvinylidene chloride, polyvinylidene fluoride, polyester and polyamide brought about greater meat adhesion than the ones of low wettability such as polyethylene and polypropylene. If polyethylene casing was modif...

Cell therapy with endothelial progenitor cells (EPCs) is an emerging therapeutic option to promote angiogenesis or endothelial repair. Although the release of angiogenic paracrine factors is known to contribute to their therapeutic effect, little is known about their release of proinflammatory factors and expression of proinflammatory adhesion molecules. "Early" EPCs and "late" EPCs were isolat...

the adhesive interaction between tumor cells and the host cells or the extracellular matrix plays a crucial role in tumor metastasis. to evaluate the mediation of cell adhesion by daphne mucronata, an anti-cancer medicinal plant in iranian folk medicine, the adhesion of thrombin activated human platelets to the cultured monocytes or hl-60 cells was investigated under the effect of the plant ext...

objective(s)the purpose of this study holds, for the first time, an evaluation of the intraperitoneal curcumin lavage on the development of post-operative intra-abdominal adhesions.materials and methodsthirty male wistar rats were randomized into five groups. the rats were administered anesthesia and underwent surgery in order to create intra-abdominal adhesions. before the abdomen was closed, ...

mast cells play an important role in a variety of inflammatory diseases, particularly asthma and atopy. peroxisome proliferator-activated receptor gamma (pparγ) is a member of the large nuclear hormone  receptor  transcription  factor  superfamily, and  has  been  recently implicated in the anti-inflammatory response. to investigate a possible role for pparγ in human mast cells, we studied the ...

introduction: adhesion formation after pelvic surgery is still a major cause of several morbidities such as infertility, pain, bowel obstruction and subsequent intra-operative complications. our aim was to investigate the effects of d-penicillamine in preventing adhesion formation in rat uterine horn. methods: this experimental trial was conducted on 30 rats. the rats were randomly assigned to ...
