In 1998, we realized that we had discovered a breakthrough in solving the 500LP— so we had something to offer regarding the Y2K problem. We immediately informed all the relevant Y2K solution providers and people concerned with the Y2K awareness campaign. In answer to our emai...

BACKGROUND & OBJECTIVES Identification of mycobacteria to the species level is of therapeutic significance. Conventional methods are laborious and time consuming so we did 16S rRNA sequencing using a commercial MicroSeq sequencing kit, which includes DNA sequencing with software package for identification and phylogenetic analysis of clinical mycobacterial isolates. METHODS A total of 47 myco...

Very large DNA molecules were separated by electrophoresis in horizontal slab gels of dilute agarose. Conditions of electrophoresis were developed using intact DNA molecules from the bacterial viruses lambda, T4 and G. Their DNAs have molecular weights (M) of 32 million, 120 million, and 500 million, respectively. Several electrophoresis conditions were found which give sufficiently high mobili...

Based on the property that oxalic acid has the effect on the replacement of dibromochloroarsenazo in zirconium(IV)-dibromochloroarsenazo complex to produce hyperchromic effects in 1.26 M hydrochloric acid medium, a novel method for the determination of trace oxalic acid by spectrophotometry was developed. The concentration of oxalic acid is linearly related to the absorbance at 500 nm. Beer’s l...

PURPOSE This phase I trial evaluated intraperitoneal (i.p.) pemetrexed, cisplatin, and paclitaxel in optimally debulked ovarian cancer. EXPERIMENTAL DESIGN Dose escalation of day 1 i.p. pemetrexed accrued three patients to each of five dose levels (60-1,000 mg/m(2)), along with day 2 i.p. cisplatin (75 mg/m(2)) and day 8 i.p. paclitaxel (60 mg/m(2)). The goals were to determine maximum tolera...

We assessed the aqueous toxicity mitigation capacity of a hydrologically managed floodplain wetland following a synthetic runoff event amended with a mixture of sediments, nutrients (nitrogen and phosphorus), and pesticides (atrazine, S-metolachlor, and permethrin) using 48-h Hyalella azteca survival and phytoplankton pigment, chlorophyll a. The runoff event simulated a 1h, 1.27 cm rainfall eve...

The operation of microscopic high-speed liquid-metal jets in vacuum has been investigated. We show that such jets may be produced with good stability and collimation at higher speeds than previously demonstrated, provided that the nozzle design is appropriate and that cavitation-induced instabilities are avoided. The experiments with a medium-speed tin jet (u 60 m/ s, Re=1.8·10, Z=2.9·10 ) show...

Spindle cell carcinoma of the breast is a rare tumor. This tumor can proliferate rapidly and cause cystic changes because of internal tissue necrosis. We evaluated a 54-year-old woman with right breast lump. Mammography showed a category four mass with a diameter of 2.5 cm. Ultrasonography (US) revealed a complex cystic lesion, and fine-needle aspiration (FNA) cytology demonstrated bloody fluid...
