In chronic wounds, excess levels and activity of proteases such as elastase and plasmin have been detected. Oxidised regenerated cellulose/collagen matrix (ORC/collagen matrix) has been reported to ameliorate the wound microenvironment by binding and inactivating excess proteases in wound exudates. In this study, the levels and activity of elastase and plasmin in wound exudates of pressure sore...

BACKGROUND Many studies have investigated whether pleural cholesterol levels can aid in diagnosis of pleural exudates, and the results have varied considerably. To gain a more reliable answer to this question, we meta-analyzed the literature on using pleural cholesterol or the ratio of cholesterol in pleural fluid to cholesterol in serum (P/S cholesterol ratio) as diagnostic tests to help ident...

The identification of eye diseases in retinal images is the subject of several researches in the field of medical image processing.We developed a computerized aid diagnosis system to help specialists by displaying useful information such as the location of abnormalities in fundus images .This paper proposes three efficient approaches:for automatic detection of optic disk(OD) and exudates , and ...

Exudates are the primary signs of diabetic retinopathy which are mainly cause of blindness. It could be prevented with an early screening process. Pupil dilation is required in the normal screening process but this affects patients’ vision. Automatic computerized screening should facilitate screening process, reduce inspection time and increase accuracy. In this paper we proposed an automatic m...

Diabetic retinopathy is a complication of diabetes that is caused by changes in the blood vessels of the retina. The symptoms can blur or distort the patient's vision and are a main cause of blindness. Exudates are one of the primary signs of diabetic retinopathy. Detection of exudates by ophthalmologists normally requires pupil dilation using a chemical solution which takes time and affects pa...

Recent reports (1, 2, 3) that serum from febrile patients and exudates from tuberculous pleurae exert an apparently non-specific agglutinating effect upon certain gram-positive cocci have prompted the publication of similar results concerning the properties of exudates obtained from patients suffering from various acute manifestations of rheumatic fever. During the course of a search for agglut...

Fertilization is widely acknowledged as being an essential practice to improve forest productivity in ecosystems. However, too little consideration has been given the taxonomic and functional compositions of rhizosphere soil microbes their interactions with root exudates under different fertilizer regimes plantations. Here, we investigated effects four typical (CK, no fertilizer; CF, compound O...

Objectives: The aim of this study was to investigate levels of matrix metalloproteinase-8 (MMP-8) and substance P (SP) in root canal exudates during root canal treatment (RCT) of nonvital, painful teeth. Materials and Methods: Patients scheduled for nonsurgical RCT were prospectively selected; the study was performed after obtaining informed consent from the patients and was approved by the Ins...

Root exudates released into soil have important functions in mobilizing metal micronutrients and for causing selective enrichment of plant beneficial soil micro-organisms that colonize the rhizosphere. Analysis of plant root exudates typically has involved chromatographic methods that rely on a priori knowledge of which compounds might be present. In the research reported here, the combination ...

The paper presents a new approach for medical image segmentation. Exudates are a visible sign of diabetic retinopathy that is the major reason of vision loss in patients with diabetes. If the exudates extend into the macular area, blindness may occur. Automated detection of exudates will assist ophthalmologists in early diagnosis. This segmentation process includes a new mechanism for clusterin...
