Rhizobia elicit on their specific leguminous hosts the formation of new organs, called nodules, in which they fix nitrogen. The rhizobial nodulation genes specify the synthesis of lipo-chitooligosaccharide signals, the Nod factors (NFs).

A plant flavone, luteolin, induces expression of Rhizobium meliloti nodulation genes.
Science, 1986The symbiotic interaction of Rhizobium meliloti and alfalfa results in the formation of nitrogen-fixing root nodules. Rhizobium meliloti nodABC genes are required for the early host responses of cortical cell divisions and root hair curling.

The various techniques for evaluating a thyroid nodule are described and their relative values analyzed. Fine-needle aspiration is the most sensitive and specific test among the leading techniques, the others being ultrasonography and thyroid scanning. A combination of tests is also analyzed.

Hepatocellular dysplastic nodules
Hepatology Research, 2007The multistep process of hepatic carcinogenesis is mirrored by the morphologic classification of lesions detectable in cirrhosis, which include large regenerative nodules (LRN), low grade dysplastic nodules (LGDN), and high grade dysplastic nodules (HGDN). The latter belong to the “bordeline malignancy” category requiring accurate distinction from well‐

Quelprud's Nodule: a post-auricular cartilaginous nodule
The Journal of Laryngology & Otology, 1990AbstractA number of minor variations to the configuration of the external ear are well recognized. This paper brings attention to one entity which is characterized by a small cartilaginous nodule or prominence arising from the posterior surface of the pinna and which we have named Quelprud's nodule.

Previous greenhouse studies have demonstrated that photosynthesis in some cultivars of first(GR1) and second-generation (GR2) glyphosate-resistant soybean was reduced by glyphosate.

Benign thyroid nodules are highly prevalent in iodine-deficient areas. Histologically, benign thyroid nodules are characterized by morphologic criteria as encapsulated lesions (true adenomas) or adenomatous nodules, which lack a capsule. On functional grounds, nodules are classified as either “cold,” “normal,” or “hot,” depending on whether they show ...

A 42-year-old woman presents with a palpable mass on the left side of her neck. She has no neck pain and no symptoms of thyroid dysfunction. Physical examination reveals a solitary, mobile thyroid nodule, 2 cm by 3 cm, without lymphadenopathy. The patient has no family history of thyroid disease and no history of external irradiation.
