Diabetic Retinopathy is one of the leading causes of blindness in developed countries. Hard exudates have been found to be one of the most prevalent earliest clinical signs of retinopathy. Thus, automatic detection of hard exudates from retinal images is clinically significant. In this study, an automatic method to detect hard exudates is proposed. The algorithm is based on mixture models to dy...

The purpose of this present study was to differentiate transudates and exudates in pleural effusions. Oxidative stress has been associated with various respiratory disorders. Ninety patients of pleural effusions of diverse etiologies were participated in this study. Subjects underwent diagnostic thoracentesis and standard biochemical parameters (total protein, lactate dehydrogenase, glucose, MD...

The effect of root exudates from non-mycorrhizal and mycorrhizal cucumber (Cucumis sativus L.) plants colonized by one of three arbuscular mycorrhizal fungi (Gigaspora rosea Nicolson & Schenck, Glomus intraradices Smith & Schenck, or Glomus mosseae (Nicolson & Gerdemann) Gerd. & Trappe) on hyphal growth of Gi. rosea and G. intraradices in axenic culture and on root colonization by G. mosseae in...

The most complex system in human body is eye. Nowadays there is increase in vision loss patients mainly due to retinal diseases. Some diseases cannot be identified early unless it affects the vision as it has no symptoms. But it can be identified by some clinical signs in the retina which cannot be viewed through naked eye but through fundus photography. Traditionally, retinal diseases are diag...

* Root exudates play a key role during the presymbiotic growth phase and have been shown to stimulate hyphal branching and the catabolic metabolism of arbuscular mycorrhizal (AM) fungal spores. * Here, the effect of root exudates on presymbiotic growth, uptake of exogenous carbon and transcript levels for genes putatively involved in the carbon metabolism of germinating spores were determined. ...

Diabetic retinopathy, that affects the blood vessels of the retina, is considered to be the most serious complication prevalent among diabetic patients. If detect successfully at an early stage, ophthalmologist would be able to treat the patients by advanced laser treatment to prevent total blindness. In this paper, we propose a technique based on morphological image processing and fuzzy logic ...

We report herein the disappearance of macular hard exudates after the introduction of hemodialysis in diabetic patients. A 62-year-old woman and a 52-year-old man with diabetes mellitus showed hard exudates in the macula of the left eyes. Both patients had previously undergone panretinal photocoagulation in both eyes. During the follow-up, hemodialysis was introduced for deteriorating chronic r...

Exudates are one of the chief signs of diabetic retinopathy, which is a main root of blindness and can be prevented with an early screening process. In this article, authors have attempted to detect exudates using back propagation neural network. The publicly available diabetic retinopathy dataset DIARETDB1 has been used in the evaluation process. To prevent the optic disk from interfering with...

It has been estimated that between 40 and 60 % of the assimilated carbon is diverted to roots released in rhizosphere form root exudates. Root exudates thus define a complex mixture low high molecular weight compounds, including carbohydrates, amino acids, organic, proteins, but also broad spectrum specialized molecules, such as flavonoids, glucosinolates, terpenoids, or alkaloids. favour soil ...
