Mineralization of a fluorotelomer surfactant containing C6F13 end-group (FSC), in hot and superheated water was studied. The process optimized by variation parameters such as temperature the presence or absence O2, Ar, KMnO4 K2S2O8. Treatment FSC with combination O2 efficiently decomposed to F?, SO42?, CO2. Specifically, when aqueous (34.8 ?mol) (0.50 mmol) were reacted at 350 °C for 18 h under...

In the germarium of the Drosophila ovary, germline cysts are encapsulated one at a time by a follicular epithelium derived from two follicle stem cells (FSCs). Ovaries in flies mutant for the serine/ threonine kinase Pak exhibit a novel phenotype, in which two side-byside cysts are encapsulated at a time, generating pairedegg chambers. This striking phenotype originates in the pupal ovary, wher...

[1] We present major, volatile, and trace elements for quenched glasses from the Fonualei Spreading Center, a nascent spreading system situated very close to the Tofua Volcanic Arc (20 km at the closest), in the northeast Lau Basin. The glasses are basalts and basaltic andesites and are inferred to have originated from a relatively hot and depleted mantle wedge. The Fonualei Spreading Center sh...

BACKGROUND: Faisalabad is the third biggest city of Pakistan. Majority of the population is Punjabi while other ethnic groups are in minority. AIMS: The present study was undertaken to find the mutations causing β-thalassemia in Faisalabad Pakistan. MATERIALS AND METHODS: A total of 285 β-globin alleles from 143 unrelated families having at least one transfusion-dependent child were analyzed by...

In whiskered animals, activity is evoked in the primary sensory afferent cells (trigeminal nerve) by mechanical stimulation of the whiskers. In some cell populations this activity is correlated well with continuous stimulus parameters such as whisker deflection magnitude, but in others it is observed to represent events such as whisker-stimulator contact or detachment. The transduction process ...

Current evidence suggests that alterations within acinar cells are responsible for the development of acute pancreatitis. After inducing acute pancreatitis in rats by pancreatic duct obstruction, we analysed, using flow cytometry, the progressive changes in cytosolic Ca2+ concentrations in individual acinar cells from the earliest stages to 48 h after obstruction to investigate whether parallel...

Antibody reagents were made specific for each of the two forms of human SC, FSC and BSC, which is an integral part of the sIgA molecule. With the fluorescent antibody method the cytological and histological localization of FSC, BSC, and alpha-chains has been studied in various human mucous membranes. SC was present in columnar epithelial cells of the intestines and in the cells of serous acini ...

Identifying potent drug combination from a herbal mixture is usually quite challenging, due to a large number of possible trials. Using an engineering approach of the feedback system control (FSC) scheme, we identified the potential best combinations of four flavonoids, including formononetin, ononin, calycosin, and calycosin-7-O- β -D-glucoside deriving from Astragali Radix (AR; Huangqi), whic...

UNLABELLED Sentinel node lymphoscintigraphy using colloidal particles has become common practice at many institutions. The ideal particle size for colloids such as filtered (99m)Tc-sulfur colloid ((99m)Tc-FSC) in sentinel node studies is 15-100 nm. It is reported that the use of a reduced heating time during the reconstitution process results in an increased number of smaller particles (<30 nm)...
