We present high-resolution imaging of the region around the Herbig Ae/Be star LkHα 234 in the 10μm and 17μm atmospheric windows and in the H2 v=1-0 S(1) line and adjacent continuum. LkHα 234 is unresolved at mid-infrared wavelengths (FWHM < 1.3′′) and has a decreasing spectrum compatiblewith an accretion disk.A coldmid-infrared companion is revealed 2.7′′ to the north-west of the optical star, ...

Arsenic adsorption and exchange with phosphorus on indium phosphide ~001! have been studied by scanning tunneling microscopy, low-energy electron diffraction, and x-ray photoelectron spectroscopy. The surface phase diagram as a function of temperature has been obtained. At 285 °C, arsenic adsorbs on the InP s(234) surface (P coverage50.25 ML), forming a disordered (134) with double layers of ar...

In this study, PCR assays targeting different Leishmania heat-shock protein 70 gene (hsp70) regions, producing fragments ranging in size from 230-390 bp were developed and evaluated to determine their potential as a tool for the specific molecular diagnosis of cutaneous leishmaniasis (CL). A total of 70 Leishmania strains were analysed, including seven reference strains (RS) and 63 previously t...

The regulation mechanism of female-predominant expression of the mouse Cyp2b9 gene was investigated in vivo and in vitro. Luciferase reporter assay revealed that the -234/-194 region of the Cyp2b9 gene may be responsible for sexually dimorphic expression. There is a predicted forkhead box A2 (FoxA2) (hepatic nuclear factor 3beta)-binding site in this region. Chromatin immunoprecipitation assay ...

The objective of this research work was to mask the intense bitter taste of fexofenadine hydrochloride using weak cation exchange resins and to formulate orodispersible tablet of taste masked drug-resin complex. Five resins indion 204, indion 234, indion 414, kyron T-114 and kyron T-314 were used. Depending on maximum drug loading capacity of resins indion 234 and kyron T-314 were finalized for...

To assess the frequency of TP53 alterations and their correlation with other genetic changes and outcome in acute myeloid leukemia with complex karyotype (CK-AML), we performed integrative analysis using TP53 mutational screening and array-based genomic profiling in 234 CK-AMLs. TP53 mutations were found in 141 of 234 (60%) and TP53 losses were identified in 94 of 234 (40%) CK-AMLs; in total, 1...

The aim of this study was to assess the prevalence and severity of dental fluorosis in permanent teeth and its association with dental caries in a group of school children living in a nonfluoridated community of Wielkopolska (Poland). The sample consisted of 470 children aged 6–14 years. Dental fluorosis was described using the Thylstrup and Fejerskov Index (TFI). Dental caries experience was a...

We adapted an inhibition assay for methotrexate, involving dihydrofolate reductase from bovine liver, for use with a discrete analyzer (the ABA-100). The analyzer waused both for dilution and a 5-mm pre-incubation of the sample with NADPH-enzyme reagent, and for the assay itself. The standard curve was linear between 10 and 120 tg/L. Without pre-incubation the standard curve was nonlinear. The ...

-We present new precise U-Th ages of well-preserved coral specimens collected from the island of Barbados, West Indies, and the atoll of Mururoa, French Polynesia. Our new data confirm the ages attributed to oxygen isotope stage 7 in the framework of the Milankovitch theory (BERGER, 1978; MARTINSON et al., 1987). By using thermal ionization mass spectrometry (TIMS), it is also possible to quant...
