Mucosal fenestration associated with maxillary first molar is rare but challenging to treat when there loss of marginal bone along buccally oriented root angulation. The exposed within the oral cavity large mucosal defect makes it susceptible plaque accumulation and infection. This case report showcases management mesiobuccal Left Maxillary by resection Platelet rich fibrin membrane.

The biologic relevance of the increased platelet-associated IgG (PAIgG) on platelets from patients with idiopathic thrombocytopenic purpura (ITP) is unclear. Platelets from ITP patients are often larger than normal, and it is possible that the increased IgG is not specific but passively related to platelet size. The measurement of platelet-bound albumin could provide information concerning the ...

BACKGROUND Platelet dysfunction is a well-established disturbance in haemodialysis (HD) patients. Propyl gallate is a synthetic platelet activator with the property to stimulate platelet aggregation. The aim of the present study was to evaluate the influence of a single haemodialysis session on propyl gallate-induced platelet aggregation. METHODS Thirty-nine HD patients were enrolled in the s...

Plasma proteins were covalently immobilized onto polyacrylonitrile (PAN) membrane to evaluate the hemocompatibility and anaphylatoxin formation. This is used as a model to study the effect of protein-adsorption on the blood-contacting response of hemodializing membranes. The proteins used were either platelet-adhesion-promoting collagen (COL) or platelet-adhesion-inhibiting human serum albumin ...

Vitamin A and other retinoids are known to have an effect on biological membranes. We measured the effects of retinol, retinoic acid and retinyl palmitate on in vitro osmotic fragility, spontaneous hemolysis and membrane microviscosity of human red blood cells (RBC)., Incorporation of retinol into the erythrocyte membrane was also studied. The effect of large doses of retinol on adenosine dinuc...

In this study we have evaluated the influence of biomaterial nano-topography on platelet adhesion and activation. Nano-porous alumina membranes with pore diameters of 20 and 200 nm were incubated with whole blood and platelet rich plasma. Platelet number, adhesion and activation were determined by using a coulter hematology analyzer, scanning electron microscopy, immunocytochemical staining in ...

The effects of alpha-tocopherol (vitamin E) deficiency on membrane properties of platelets were studied to determine if vitamin E has a measureable stabilizing role in biological membranes. Three groups of rats and three of mice were studied: two groups consisted of Fisher strain rats and one of Sprague-Dawley rats fed a Draper corn oil diet with and without high levels of supplementary vitamin...

Thrombocytopenia occurs when a patient suffers from an abnormally low platelet count in the peripheral blood; usually a result of disease, trauma, or cancer treatment. To treat these patients, it is estimated that two million platelet transfusions are performed in the U.S. each year. This high demand for platelets has created a clinical demand for studying the causes of thrombocytopenia and alt...
