pulmonary alveolar proteinosis, (pap) is a rare disease of unknown etiology, characterized by accumulation of intra-alveolar proteinaceous material which is rich in lipid and positive on periodic acid-schiff stain. two clinically different pediatric types have been defined as congenital pap which is fulminant and fatal, and a late-onset pap which is similar to the adult form and less severe. ei...

The postnatal maturation of the vallate papilla and its taste buds was quantitatively investigated in rats by ligh microscopy. Specifically, we measured postnatal increases in the size of mature vallate taste buds and the vallate papilla, increases in the thickness of the gustatory epidermis, and increases in the number of mature taste buds and taste cells per bud. Mature taste buds, defined as...

A simple and efficient fingerprinting method for chrysanthemum buds was developed with the aim of establishing a quality control protocol based on biochemical makeup. Chrysanthemum bud samples were successively extracted by water and alcohol. The fingerprints of the chrysanthemum buds samples were obtained using capillary electrophoresis and electrochemical detection (CE-ED) employing copper an...

Yeast strains were constructed carrying multiple mitochondrial markers conferring resistance to the inhibitors erythromycin, chloramphenicol, paromomycin and oligomycin. A pedigree analysis of two crosses was made by micromanipulating buds from zygotes. The first few daughter buds isolated from the zygotes sometimes gave rise to diploid clones which had a mixture of mitochondrial types. All pos...

The blueberry bud mite (BBM), Acalitus vaccinii (Keifer) , is gaining importance as a pest of southern highbush blueberries. During a BBM population development study in a northcentral Florida location, an epizootic was observed, and the mesothermic acarine mycopathogen, Hirsutella thompsonii (Fisher), was identified as the causal organism. In order to better understand the progression of an ep...

Auxin and cytokinin (CTK) play important roles in regulating the growth of rice tiller buds. Auxins inhibit bud growth and CTK, which are regulated by auxins, promote growth. However, little is known about the underlying molecular mechanisms. Here, we studied auxin/CTK regulation in Nanjing 44 rice, a japonica cultivar. After full heading, we cut off the roots and removed the panicles. The till...

The rat vallate papilla is bilaterally innervated by the IXth nerve whose axons are required for the normal development of its several hundred taste buds. Temporary denervation during the developmental sensitive period for taste buds prevented most vallate taste buds from forming. Specifically, removing one IXth nerve and crushing the other in 3 day old neonates eliminated axons from the vallat...
