Tomato mosaic virus was reported from jasmine in Florida. We present the first complete genome sequence of a tomato mosaic virus isolate from this woody perennial plant in the United States.

In this paper, we reveal a remarkable connection between the Thue-Morse sequence and the Koch snowflake. Using turtle geometry and polygon maps, we realize the Thue-Morse sequence as the limit of polygonal curves in the plane. We then prove that a sequence of such curves converges to the Koch snowflake in the Hausdorff metric. In the final section we consider generalized Thue-Morse sequences an...

Metalaxyl is frequently used to protect a variety of crops from fungal diseases. This study aims establish method for the determination metalaxyl in Chinese bayberry, fresh Dendrobium officinale (D. officinale), and dried D. by gas chromatography-tandem mass spectrometry (GC-MS/MS) further assess dietary risk. The samples were extracted with acetonitrile purified dispersed solid phase extractio...

Among the essential elements of a theory of disease is the set of criteria that must be satisfied to establish that some specific factor is the cause of a particular disease. For example, in the germ theory various nonequivalent criteria have been proposed for establishing that specific micro-organisms cause particular diseases.' Perhaps the most famous criteria are the conditions known as Koch...

Cnidium officinale Makino and Capsella bursa-pastoris are used as traditional herbs with diverse medicinal effects, including the inhibition of inflammation, reduction of blood pressure and as diuretics, however, the anti-cancer effects of C. officinale Makino and C. bursa-pastoris are poorly defined. The aims of this study were to evaluate the effects of methanol extracts of C. officinale Maki...

The year 2005 marks the 100th anniversary of Robert Koch's Nobel Prize. Here, we describe the scientific career of Robert Koch, the discoverer of the etiologic agent of tuberculosis but also of those of anthrax, cholera and wound infections. Equally important, Koch developed the methodologies and concepts that made medical microbiology a scientific discipline. Despite great efforts, however, Ko...

Description A perennial herb with a subterranean, digitately branched rhizome producing stems up to 1.50 m in height with linear lanceolate sheating leaves (5-30 cm long and 8-20 mm wide) that are alternate, smooth and pale green. Flower stems shorter than leaf stems and bearing a few flowers, each surrounded by a thin bract and situated in axils of large greenish yellow obtuse bracts, which ar...

In the preceding invest,igations (1, 2) the rate of turnover of lipids was found to be slower in the brain of adult rats than in other organs (liver and intestine) studied for comparison. In this investigation lipid metabolism was studied during the time of its greatest activity in nervous tissue-the period known to morphologists as that of myelination. The process of myelination has been littl...
