INTRODUCTION Rhizospheres, the most active interfaces between plants and soils, play a central role in the long-term maintenance of the biosphere. The anti-erodibility of soils (AES) regulated by the root exudates is crucial to the soil stability in the rhizospheres. However, scientists still debate (1) the key organic matter of the root exudates affecting the AES and (2) the interspecific vari...

Diabetic retinopathy (DR) is one of the leading causes of blindness in the world among patients suffering from diabetes. It is an ocular disease and progressive by nature. DR is characterized by pathologies, namely, micro aneurysms, hard exudates, soft exudates, hemorrhages, etc. The presence of exudates is the prominent sign of non-proliferative DR. To successfully detect exudates, it is usefu...

Diabetic Retinopathy (DR) is one of the main causes of vision loss in the world among patients suffering from diabetes. DR is a chronic eye disease, which can be controlled by regular checkup & treatment. If left untreated, loss of vision occurs gradually and become blind. The detection and diagnosis of DR is important. DR is characterized by its features like, micro aneurysms (MAs), hemorrhage...

purpose: to evaluate the influence of different confounding factors on the effect of intravitreal triamcinolone acetonide injection for refractory diabetic macular edema. methods: in a prospective placebo-controlled randomized clinical trial, 88 eyes with refractory diabetic macular edema were randomly assigned into two groups including 45 in the treatment group (4 mg intravitreal triamcinolone...

A new method for the detection of blood vessels that improves the detection of exudates in fundus photographs. The method starts with pre-processing to enhance the input image. The initial estimation of exudates is obtained by segmenting the optic disc and blood vessels from the fundus image. In order to segment the optic disc and blood vessel separate algorithm were used. First, optic disc is ...

Laboratory and green house experiments were conducted to ascertain the effect of exudates (from vegetative parts weeds soaked in water) different ages (36hrs, 72hrs 120hrs) from three common weed species (namely, Chromolaena odorata, Ageratum conyzoides Cyperus esculentus) on seed germination seedling growth tomato (Lycopersicum esculentum). Tomato seeds sown petri-dishes filter paper moistened...

Plants have developed a wide-range of adaptations to overcome nutrient limitation, including changes to the quantity and composition of carbon-containing compounds released by roots. Root-associated bacteria are largely influenced by these compounds which can be perceived as signals or substrates. Here, we evaluate the effect of root exudates collected from maize plants grown under nitrogen (N)...
