Diabetic retinopathy is recognised as one of the most common causes of blindness (Aiello et al., 1998). It can however be diagnosed early based on various features that can be detected in eye fundus images. One of these indicators is exudates which are typically formed in groups or rings surrounding leakage of plasma and often appear yellowish in the image. An example of a retinal image with ex...

Root exudates play a major role in the mobilization of sparingly soluble nutrients in the rhizosphere. Since the amount and composition of major metabolites in root exudates from one plant species have not yet been systematically compared under different nutrient deficiencies, relations between exudation patterns and the type of nutrient being deficient remain poorly understood. Comparing root ...

Endophytes have a symbiotic relationship with the different parts of plants and could play a very important role in supporting the plant growth. In present study, 11 most efficient isolates were selected out of more than 200 endophytic bacteria isolated previously from roots of chickpea (Cicer arietinum), field pea (Pisum sativum), Lucerne (Medicago sativa), wheat (Triticum aestivum) and oat (A...

The components of the root exudates from two transgenic insect-resistant cotton lines and their parental cotton lines, and their effects on the growth of Fusarium oxysporum were investigated. The results demonstrated that the resistance of transgenic insect-resistant cotton to F. oxysporum was significantly reduced compared with their parental lines. Likewise, the root exudates from transgenic ...

A severe root rot of tomato caused by Meloidogyne incognita and Rhizoctonia solani was associated with nutrient mobilization into gall tissue and root exudation. Root decay did not develop when root exudates were continuously removed by leaching. When leachates were collected from M. incognita-infected and control roots and applied to roots of tomatoes inoculated with R. solani alone, roots rec...

Molecules exuded by plant roots are thought to act as signals to influence the ability of microbial strains to colonize the roots and to survive in the rhizosphere. Differential bacterial responses to signals from different plant species may mediate the selection of specific rhizosphere populations. Very little, however, is known about the effects of plant exudates on patterns of bacterial gene...

The inhibitory effect of propiconazole on strigolactone (SL) production and Striga hermonthica emergence were evaluated using rice plants. A significant reduction in SL levels was detected root exudates after treated with different doses propiconazole. Propiconazole induced second tiller bud outgrowth seedlings. In accordance the results 4-deoxyorobanchol exudates, propiconazole-treated attenua...

Root canal samples, taken from periapical tissue exudates during routine root canal treatment procedures, were processed for identification of tumor necrosis factor using a mouse anti-human monoclonal antibody and enzyme-linked immunosorbent assay. Detectable levels of tumor necrosis factor were identified in periapical tissue exudates in chronic apical periodontitis.

The samples of pleural fluid obtained by thoracentesis for the diagnosis of transudates and exudates shall follow a routine of collection and preservation for an appropriate laboratorial analysis. Equally, fragments of pleura biopsy obtained for the differential diagnosis of the exudates should be collected in a systematic way in order to optimize the diagnosis and facilitate the institution of...

Blood and pleural exudate samples were obtained from 16 patients receiving intermittent or continuous infusions of vancomycin after lung surgery. The areas under the concentration-time curves for blood and pleural exudates were identical for both administration schedules, while continuous infusion allowed the concentrations in pleural exudates to be more sustained (mean concentration, 12 mg/lit...
