Nodule ultrastructure and initial growth of Anadenanthera peregrina (L.) Speg. var. falcata (Benth.) Altschul plants infected with rhizobia
(Oxford University Press, 2002-08-01)
The anatomy and ultrastructure of root nodules of Anadenanthera peregrina var. falcata (Leguminosae-Mimosoideae) were analysed, as was plant growth. To ensure that nodules developed, seedlings were inoculated with a mixture ...
Laryngeal Web as a Possible Cause for Nonabsorption of Vocal Nodules in Boys After Puberty
(Elsevier B.V., 2019-07-01)
Objectives: Vocal nodules are frequent in children and tend to be reabsorbed after puberty, especially in boys. The aims of the present study were to analyze the progression of nodules in boys after puberty and to investigate ...
Proposal to utilize simplified Swensen protocol in diagnosis of isolated pulmonary nodule
(Royal Soc Medicine Press Ltd, 2013-09-01)
Background: The problem of diagnosing whether a solitary pulmonary nodule is benign or malignant is even greater in developing countries due to a higher prevalence of infectious diseases. These infections generate a large ...
Alterations of xylem transport of key metabolic products of assimilatory activity in soybean: do similar alterations occur in roots and nodules?
(2022-01-01)
The dynamics of changes in key metabolites of N metabolism were investigated simultaneously in roots, nodules and xylem sap following treatments that turn on and off symbiotic N2 fixation in the nodules and nitrate ...
Short-Term Molecular Acclimation Processes of Legume Nodules to Increased External Oxygen Concentration
(Frontiers Media January 2016 |Volume 6 | Article 1133, 2016)
Nitrogenase is an oxygen labile enzyme. Microaerobic conditions within the infected zone of nodules are maintained primarily by an oxygen diffusion barrier (ODB) located in the nodule cortex. Flexibility of the ODB is ...
Production of reactive oxygen species in peanut nodules
(Communications in Plant Sciences, 2013-03)
In this study, it was investigated the reactive oxygen species (ROS) production in peanut nodules at three peanut growth stages (R): R1 (flowering), R4 (full pod) and R6 (full seed). Analysis of ROS production showed that ...
Autoregressive decomposition and pole tracking applied to vocal fold nodule signals
(2007-08-01)
This letter describes a novel algorithm that is based on autoregressive decomposition and pole tracking used to recognize two patterns of speech data: normal voice and disphonic voice caused by nodules. The presented method ...
Perceptual and acoustic parameters of vocal nodules in children
(Elsevier B.V., 2014-02-01)
Vocal nodules constitute the major cause of dysphonia during childhood. Auditory-perceptual and acoustic vocal analyses have been used to differentiate vocal nodules from normal voice in children.Purpose: To study the value ...
