(1) The subcutaneous nodule , 1.7 cm across, was excised under local anaesthetic.

(2) A few people still poke around what is left of the mine dumps, but a datolite nodule is rarely found.

(3) Computed tomography showed a solitary nodule in the right lobe of the liver.

(4) The sediment was cemented with iron carbonate to form a hard nodule distinct from the shale around it.

(5) The most common presentation for thyroid or salivary gland cancer is an asymptomatic nodule within the gland.

(6) The most highly prized datolites have concentrated copper inclusions near the center of the nodule and are pinkish-gray in color.

(7) A thyroid nodule is a palpable swelling in a thyroid gland with an otherwise normal appearance.

(8) It tends to appear as a papule or nodule with an epithelialized, pearly appearance, but may ulcerate in some cases.

(9) Others contain cores of malachite that constitute up to about 30 percent of the nodule .

(10) Endoscopy evaluation revealed an antral nodule , which was biopsied.

(11) In these steep underwater cliff areas were chimneys of gravel that contained datolite nodules .

(12) It has been estimated by some collectors that tons of the nodules were recovered from this dump.

(13) The addition of magnesium to molten cast iron, to produce nodular iron, has been a routine practice for over 25 years.

(14) However, root nodules do not use nitrogen gas efficiently in the presence of a significant level of nitrate in the soil, because nitrate inhibits nodulation and nitrogenase activity.

(15) Rhizobial bacteria generally enter roots of legumes via root-hairs and induce the formation of root nodules .

(16) Roots of individual plants were visually classified into two groups: nodulated and nonnodulated, as previously described.

(17) This interaction culminates in the formation of root nodules and in the differentiation of bacteria into bacteroids, which are capable of reducing atmospheric nitrogen into ammonia.

(18) Historically, similar nodules were collected from the upper levels of the Centennial mine.

(19) This is seen in longstanding sarcoidosis, in which asymptomatic, violaceous nodules are seen on nose, fingers, and ears.

(20) Individual nodules range from a fraction of an inch to more than 14 inches across.
