A split-root growth system was employed to evaluate the effect of NaCl on nodule formation by soybean (Glycine max L. Merr. cv Davis). By applying the salinity stress and rhizobial inoculum to only one-half the root system, the effects of salinity on shoot growth were eliminated in the nodulation process. Rhizobium colonization of inoculated root surfaces was not affected by the salt treatments...

although tuberculosis involves every organ and has a wide range of clinical manifestation, however involvement of the thyroid gland is rare. we report a case of a 25-yr-old female with supraclavicular lymphadenitis that developed nodular swelling of the thyroid and had symptoms and sonographic features mimicking a nodule with a cystic component. the diagnosis was made by using fine needle aspir...

A framework for nodule feature-based extraction is presented to classify lung nodules in low-dose CT slices (LDCT) into four categories: juxta, well-circumscribed, vascularized and pleural-tail, based on the extracted information. The Scale Invariant Feature Transform (SIFT) and an adaptation to Daugman's Iris Recognition algorithm are used for analysis. The SIFT descriptor results are projecte...
