The competitive host-guest encapsulations of palmityl chloride-modified amphiphilic hyperbranched poly(amido-amine) (HPAMAM-PC) and poly(sulfone-amine) (HPSA-PC) to selected pairs of dyes are reported. Watersoluble and chloroform-insoluble dyes, such as methyl orange (MO), methyl blue (MB), rose bengal (RB), fluorescein sodium (FSS), eosin Y (EY) and phloxine B (PB), can be transferred from aqu...

Ž . The Taura syndrome TS is one of the viral shrimp diseases that has most affected cultivation of the shrimp Litopenaeus Õannamei in America. We analyzed the presence of TS, from its first detection in May 1995 in 75% of the shrimp farms of the Guasave district in Sinaloa State, Mexico, and its progressive spreading from the north toward the central and southern zones of the ́ state, to the di...

A simple, rapid, highly sensitive and selective non-extraction spectrophotometric sequential injection analysis with lab-at-valve (SIA-LAV) methods for the determination of bismuth(III) have been developed based on formation a specific ion association complex (IA) between tetraiodobismuthate(III) anion polymethine dye Astra Phloxine (AP). The changes in absorption spectra resulting from IA are ...

UNLABELLED Lymph node metastasis is an important prognostic factor in prostate cancer (PC). The aim of this prospective study was to validate, through laparoscopic surgery, the accuracy of the isotopic sentinel lymph node (SLN) technique correlated with hyperextensive pelvic resection (extended pelvic lymphadenectomy dissection) in patients with localized PC, candidates for local curative treat...

The principal indication of performing a frozen section is to obtain a definite immediate diagnosis, on the basis of which a surgical decision will be made. Immediate diagnosis allows the surgeon to proceed with further therapy without any delay. A definite immediate diagnosis is said to be dependent on the reliability of frozen sections. Many authors have carried out frozen section study on so...

The synthetic food dyes studied were rose bengal (RB), phroxine (PL), amaranth, erythrosine B (ET), allura red, new coccine, acid red (AR), tartrazine, sunset yellow FCF, brilliant blue FCF, and indigo carmine. First, data confirmed that these dyes were not substrates for CYP2A6, UGT1A6, and UGT2B7. ET inhibited UGT1A6 (glucuronidation of p-nitrophenol) and UGT2B7 (glucuronidation of androstero...
