To determine functional differences between the corpus luteum (CL) of the estrous cycle and pregnancy in cows, gene expression profiles were compared using a 15 K bovine oligo DNA microarray. In the pregnant CL at days 20-25, 40-45 and 150-160, the expressions of 138, 265 and 455 genes differed by a factor of > 2-fold (P < 0.05) from their expressions in the cyclic CL (days 10-12 of the estrous...

HEN a stock of Drosophila melanogaster with chromosome 2 marked by wclot, cl, produced brown-eyed flies resembling clot but with the gene in the X chromosome, it was suspected that a translocation had occurred. However, genetic tests, including crosses to a newly acquired yellow prune stock ( y , p n ) showed that a mutation had occurred at the p n locus. The new allele, symbol pn591, is comple...

The treatment of [Ru(η6-p-cymene)Cl2]2 with N,N’-(1,2-phenylene)dipicolinamide (H2L1) afforded the double salt complex [{Ru(η6-p-cymene)2-µ-Cl}L1][Ru(η6-p-cymene)Cl3], (Ru1) in moderate yields. Separately, reactions ligands (H2L1), N,N’-(4,5 dimethyl-1,2-phenylene)dipicolinamide (H2L2), and N,N’-(4-methoxy-1,2-phenylene)dipicolinamide (H2L3) presence KPF6 respective dinuclear half-sandwich Ru(I...

Stereoselective metabolism of dibenzo[a,l]pyrene (DB[a,l]P), 2chlorodibenzo[a,l]pyrene (2-Cl-DB[a,l]P) and 10-chlorodibenzo[a,l]pyrene (10-ClDB[a,l]P) by rat liver microsomes was studied and effects of the chloro substituent on the metabolism were determined. All three compounds produced trans-8,9-dihydrodiol, trans11,12-dihydrodiol, and the 7-hydroxyl derivative as major metabolic products and...

The random architecture of a commercial copolymer of poly(DL-lactic acid) and poly(ε-caprolactone), poly(DL-lactide-co-caprolactone), has been characterized by chemical structure analysis from hydrogen-1 nuclear magnetic resonance results. Moreover, spherical nanodomains have been detected in the thin films of this copolymer obtained after solvent evaporation. These nanodomains studied by atomi...

Background: Several treatment modalities have been used for cutaneous leishmaniasis (CL) with various results. In vitro and in vivo studies have shown inhibitory effects of zinc sulfate (ZnSO4) on Leishmania parasites. Objective: To compare the efficacy of intralesional injections of 2% ZnSO4 solution with meglumine antimonate (Glucantime) in the treatment of acute Old World CL. Patients ...

PURPOSE This study was conducted to determine 1) the concentration of hyaluronan (HA) in the tear films of contact lens (CL) wearers versus non-CL wearers and 2) whether HA sorbed from Biotrue, an HA-containing multipurpose solution (MPS), onto senofilcon A lenses affects the concentration of HA in tears after 2 hours of wear. PATIENTS AND METHODS Tears of habitual CL wearers and non-CL weare...
