this experiment was conducted to screening phenolic acids in root exudates of three rice cultivars (neda, taichung and sepidrood) by high performance liquid chromatography (hplc) method and to evaluate allelopathic potential of these cultivars on growth characteristics of barnyardgrass weed. the experiment was arranged in factorial based on completely randomized design with four replications in...

Exudates are a visible sign of diabetic retinopathy which is the major cause of blindness in patients with diabetes. If the exudates extend into the macular area, vision loss can occur. Automated early detection of the presence of exudates can assist ophthalmologists to prevent the spread of the disease more efficiently. Hence, detection of exudates is an important diagnostic task. Exudates are...

The first diagnostic step in pleural effusions is the separation of transudates from exudates. We aimed in present study to investigate the value of HDL/LDL ratio for distinguishing between pleural exudates and transudates. Pleural fluids (PF)from 121 patients, including 28 transudates and 93 exudates were analyzed. The levels of cholesterol, HDL cholesterol and LDL cholesterol in PF were measu...

BACKGROUND We evaluated the efficacy of intravitreal bevacizumab on diabetic macular edema with subfoveal and perifoveal hard exudates. MATERIALS AND METHODS Eleven eyes (11 patients) exhibiting diabetic macular edema with subfoveal and perifoveal hard exudates were included in this prospective, nonrandomized interventional pilot study. All patients were treated with monthly scheduled intravi...

Root exudates improve the nutrient acquisition of plants and affect rhizosphere microbial communities. The plant nutrient status affects the composition of root exudates. The purpose of this study was to examine common bean (Phaseolus vulgaris L.) root exudates under phosphorus (P) deficiency using a metabolite profiling technique. Common bean plants were grown in a culture solution at P concen...

OBJECTIVES To determine the relative usefulness of different criteria for the separation of pleural transudates from exudates. DESIGN Prospective evaluation of patients referred for thoracentesis. SETTING Community teaching hospital. PATIENTS Three hundred fifty-one consecutive patients with pleural effusions referred for thoracentesis. Fifty-four of these patients were excluded from the ...

A significant proportion of the carbon fixed by plants is transported to roots and exuded rhizosphere. Exudates may have important roles in rhizosphere, such as desorbing labile phosphorus (P) or mobilizing manganese (Mn) other metal cations. This study evaluated root exudation profiles seedlings 15 eucalypt species response a P shortage if ability exude organic compounds was related Mn accumul...

Lactoferrin was analysed with an ELISA in pleural effusions from 21 patients with malignant exudative effusions (15 carcinomas and 6 mesotheliomas), 12 patients with non-malignant exudative effusions of unknown aetiology, 11 patients with transudative effusions due to congestive heart failure, 12 patients with exudative effusions secondary to infection, and 2 patients with tuberculous effusions...

Root-secreted chemicals mediate multi-partite interactions in the rhizosphere, where plant roots continually respond to and alter their immediate environment. Increasing evidence suggests that root exudates initiate and modulate dialogue between roots and soil microbes. For example, root exudates serve as signals that initiate symbiosis with rhizobia and mycorrhizal fungi. In addition, root exu...
