Root exudates have important, yet incompletely known, roles in plant physiology, mainly in rhizosphere interactions with other organisms. Proline might play a critical role in protecting plants under stress, particularly under saline conditions. However, as far as we know, no attempts have been made to determine the proline content of root exudates. Here, we present preliminary results of the q...

Algae-derived dissolved organic matter has been hypothesized to induce mortality of reef building corals. One proposed killing mechanism is a zone of hypoxia created by rapidly growing microbes. To investigate this hypothesis, biological oxygen demand (BOD) optodes were used to quantify the change in oxygen concentrations of microbial communities following exposure to exudates generated by turf...

Exudates produced from Bermuda grass roots were collected in deionized water from sterilized Bermuda grass sod at 3-day intervals over a period of 15 days. Exudates were analyzed for total organic carbon, and characterized via Fourier Transform Infrared Spectroscopy. Exudate samples were adjusted to pH values of 4.5, 6.5, and 7.5, amended with lead and quantified for soluble and complexed lead ...

OBJECTIVE To determine frequency and associated risk factors for macular edema and retinal hard exudates in hospitalized African Americans with type 1 diabetes. SUBJECTS AND METHODS Included were 725 African Americans with type 1 diabetes who participated in the New Jersey 725. Clinical evaluations consisted of a structured clinical interview, ocular examination, stereoscopic fundus photograp...

The successful colonization of plant growth promoting rhizobacteria (PGPR) in the rhizosphere is an initial and compulsory step in the protection of plants from soil-borne pathogens. Therefore, it is necessary to evaluate the role of root exudates in the colonization of PGPR. Banana root exudates were analyzed by high pressure liquid chromatography (HPLC) which revealed exudates contained sever...

Diabetes is a group of metabolic diseases in which a person has high blood sugar. Diabetic Retinopathy (DR) is caused by the abnormalities in the retina due to insufficient insulin in the body. Diabetic Retinopathy affects 80% of all patients who had diabetes for 10 years or more, which can also lead to vision loss. The most primitive sign of Diabetic Retinopathy is Exudates. Exudates in the re...

PURPOSE To evaluate outcomes of submacular surgery to remove massive submacular hard exudates with diabetic macular edema. DESIGN Retrospective, non-comparative, interventional consecutive case series. PARTICIPANTS Fifty-six eyes of 40 patients with massive submacular hard exudates with diabetic macular edema. INTERVENTION Submacular surgery was performed to remove massive submacular hard...

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...
