HISTORY OF OPHTHALMOLOGY MICHAEL F. MARMOR
"... Abstract. G. H. A. Hansen (1841–1912) is widely known as the discoverer of the infectious cause of leprosy. It is less well known that his career was threatened by an episode involving experimentation on the eye. As a staff physician at the leprosy hospitals of Bergen, Norway, early in his career, H ..."

several unsuccessful experiments, and in 1879 he passed a cataract knife that had incised an active leprous nodule into a woman’s conjunctiva. No nodule developed, but the woman complained of pain and said she was never asked for permission. Hansen was brought to trial where eminent physicians testified
Kasai S: In vitro differentiation and calcification in a new clonal osteogenic cell line derived from newborn mouse calvaria
- J Cell Biol
, 1983
"... ABSTRACT We investigated the capacity'of a clonal osteogenic cell line MC3T3-EI, established from newborn mouse calvaria and selected on the basis of high alkaline phosphatase (ALP) activity in the confluent state, to differentiate into osteoblasts and mineralize in vitro. The cells in the grow ..."

NODULE OF TEPHROSIA PURPUREA
"... Many bacteria produce extra cellular polysaccharide (EPS) and in genera such as Klebsiella, Rhizobium, Bacillus and Streptococcus they[Delete] have been well characterized for a number of species and strains. Polysaccharides from plant sources material and their modified forms are important additive ..."

many species producing EPS. From the root nodule of this plant, five different species of bacteria were isolated and studied for their antibacterial activity. Out of five strains, two strains showed promising activity against human pathogens (Escherichia coli, Enterococcus aeruginosa, Klebsiella
GENETIC MANIPULATION OF NODULATION IN

The ranges in values of the characters studied f'or the parents and the F plants are shown in Table I. Most of the segregates flowered 2 days earlier than their paren ..."

) and low nitrogenase activity (2.2~1 mol C2H4 produced /plant per h), while line 6 showed extensive nodulation (191 mg nodule tissue / plant) and moderate to high nitrogenase activity (7.32 u mol Iq produced! plant per h). Two lines (Nos. 3 and 16) showed both high yierd and good N21'ixation (see
Pulmonary toxicity of single-walled carbon nanotubes in mice 7 and 90 days after intratracheal instillation.
- Toxicol. Sci.
, 2004
"... Nanomaterials are part of an industrial revolution to develop lightweight but strong materials for a variety of purposes. Singlewall carbon nanotubes are an important member of this class of materials. They structurally resemble rolled-up graphite sheets, usually with one end capped; individually t ..."

. The distribution of black particles in lungs 90 d after they were instilled with 0.5 mg of CB or NTs is illustrated in Most of these microscopic nodules were located beneath the bronchial epithelium and were present throughout most of the lung fields. Some appeared to extend into the bronchi as polyps
Malic Enzyme Activity in Bacteroids from Soybean Nodules
, 1989
"... Soluble extracts of Bradyrhizobium japonicum bacteroids from soybean root nodules showed substantial rates of NAD+ and NADP+ reduction which were malate and MnC12 dependent. Pyruvate was formed stoichiometrically and the NAD- and NADP-dependent rates were additive, indicating the presence of two mal ..."

Ferritins and nodulation in Lupinus luteus: iron management in indeterminate type nodules
, 2007
"... An ability to form symbiotic associations with rhizobia and to utilize atmospheric nitrogen makes legumes ecologically successful. High iron content in legume grains, partially relocated from root nodules, is an-other-nutritional-advantage of this group of plants. The ferritin complex is the major c ..."

. Interestingly, it was found that, in this type of nodule, senescence starting in the decaying zones induces ferritin accu-mulation in younger, still active, tissues. Based on the presented data, and in correlation with previous results, some aspects of the regulation of expression of lupin ferritin genes
Compensation against ineffective nodulation in soybean. Crop Sci
, 1983
"... Two cultivars of soybean [Glycine max (L.) Merr.] were inoculated with nine ratios of ineffective (SM-5) and effective (CC709) strains of Rhizobium japonicum. Plants were grown in the greenhouse and harvested after 33 days. Nitrogenase activity, total shoot N, nodule number, nodule mass, and the pro ..."

The profiles of glutamine synthetase (GS) activity in the plant fraction of nodule extracts from tropical legumes, inoculated with either fast- or slow-growing rhizobia, were analyzed by non-denaturing polyacrylamide gel electrophoresis. The electrophoretic mobility of nodule GS was plant-dependent ..."

"... The interactions of legumes with symbiotic nitrogen-fixing bacteria cause the formation of specialized lateral root organs called root nodules. It has been postulated that this root nodule symbiosis system has recruited factors that act in early signaling pathways (common SYM genes) partly from the ..."
