Association of Light’s Criteria with Pleural Fluid Procalcitonin Levels and Ultrasound Thorax with its Impact on the Management of Pleural Effusion: A Cross-sectional Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research
Introduction: Pleural effusion, the abnormal accumulation of fluid in the pleural space, affects around 1.5 million people every year. Light’s criteria is routinely employed to distinguish between transudative and exudative effusions based on the test ...

Automatic Segmentation of Exudates in Ocular Images using Ensembles of Aperture Filters and Logistic Regression [PDF]

open access: yes, 2013
Hard and soft exudates are the main signs of diabetic macular edema (DME). The segmentation of both kinds of exudates generates valuable information not only for the diagnosis of DME, but also for treatment, which helps to avoid vision loss and blindness.

Relationship between root exudation of organic carbon and physiological variables of irrigated rice cultivars

open access: yesCiência Rural, 2018
: Rhizospheric carbon resulting from root exudation is one of the substrates used by the soil microbiota, and reflects methane (CH4) emissions in anoxic environments such as irrigated rice cultivation. With the increase of the photosynthetic capacity of

Effective Fundus Image Decomposition for the Detection of Red Lesions and Hard Exudates to Aid in the Diagnosis of Diabetic Retinopathy

open access: yesSensors, 2020
Diabetic retinopathy (DR) is characterized by the presence of red lesions (RLs), such as microaneurysms and hemorrhages, and bright lesions, such as exudates (EXs). Early DR diagnosis is paramount to prevent serious sight damage.

Influence of coral and algal exudates on microbially mediated reef metabolism. [PDF]

open access: yes, 2013
Benthic primary producers in tropical reef ecosystems can alter biogeochemical cycling and microbial processes in the surrounding seawater. In order to quantify these influences, we measured rates of photosynthesis, respiration, and dissolved organic ...

Fundus Images-Based Detection and Grading of Macular Edema Using Robust Macula Localization

open access: yesIEEE Access, 2018
The macula is an oval-shaped area near the center of the human retina, and at its center, there is a small pit known as the fovea. The fovea contains large concentrations of cone cells and is responsible for sharp, colored vision.
