Hewitt and Todd (1939) occasionally noticed an obviously nonspecific increase in the antistreptolysin titer (AST) in sera that had been contaminated with certain bacteria. Independently, Lofgren (1944) has reported on the same phenomenon. In comprehensive AST studies on clinical material, Westergren several years ago paid attention to the common occurrence of unexpected rises in AST, often to e...

Translocation of Fe was studied in WF9 (Fe-efficient) and ys(1)/ys(1) (Fe-inefficient) maize (Zea mays L.) genotypes. Iron-deficient WF9 translocated more Fe to the tops than Fe-deficient ys(1)/ys(1). Malate and citrate contents of root saps increased nearly 2-fold and aconitate increased over 4-fold in both genotypes as Fe of nutrient solutions increased from 0.1 to 3 milligrams per liter. Rel...

Abstract Diabetic Retinopathy is an eye disorder that affects people suffering from diabetes. Higher sugar levels in blood leads to damage of vessels eyes and may even cause blindness. retinopathy identified by red spots known as microanuerysms bright yellow lesions called exudates. It has been observed early detection exudates microaneurysms save the patient’s vision this paper proposes a simp...

Abstract Accurate segmentation of hard exudates in early non‐proliferative diabetic retinopathy can assist physicians taking appropriate treatment a more targeted manner, order to avoid serious damage vision caused by the deterioration disease later stages. Here, an Adaptive Learning Unet‐based adversarial network with Convolutional neural and Transformer (CT‐ALUnet) is proposed for automatic e...

The effect of different membrane filters on the bioactivity of tomato root exudates was tested in an in vitro assay addressing the germination of microconidia of the soil-borne fungus Fusarium oxysporum f. sp. lycopersici. Membrane filtration of unsterile root exudates with filters of different membrane materials and filter brands resulted in an increased microconidia germination. This effect v...

Antifungal activity of water soluble exudates of pea leaves was assayed. Exudates of different nodal leaves were collected by dipping them in sterilized distilled water for different length of time and conidial germination of four non-pathogenic to pea fungi (Alternaria solani, Curvularia lunata, Helminthosporium penniseti and H. echinocloa) and one pea pathogenic to pea fungus (Erysiphe pisi) ...

Problem statement: Diabetic retinopathy is one of the most significant factors contributing to blindness and so early diagnosis and timely treatment is particularly important to prevent visual loss. Approach: An integrated approach for extraction of blood vessels and exudates detection was proposed to screen diabetic retinopathy. An automated classifier was developed based on Adaptive Neuro-Fuz...

PURPOSE We aimed to evaluate the efficacy of multidetector computed tomography (CT) imaging in diagnosis of pleural exudates and transudates using attenuation values. MATERIALS AND METHODS This retrospective study included 106 patients who were diagnosed with pleural effusion between January 2010 and June 2012. After the patients underwent chest CT, thoracentesis was performed in the first we...

Plant roots constantly secrete compounds into the soil to interact with neighboring organisms presumably to gain certain functional advantages at different stages of development. Accordingly, it has been hypothesized that the phytochemical composition present in the root exudates changes over the course of the lifespan of a plant. Here, root exudates of in vitro grown Arabidopsis plants were co...

Lessonia spicata is a key dominant species along the Pacific coast of South America, providing a habitat for many organisms. However, this role can be affected by abiotic stress, such as metals. To counteract the toxic effect, L. spicata, among other seaweeds, releases exudates that bind metals. In this study, tolerances to copper of organisms related to the kelp forest (spores of Ulva lactuca ...
