15 to 0.92 Scm(-1) and the temperature dependent resistivity follows ln rho(T) similar to T-1/2 behavior. The nanocomposites (80 wt % of ZnFe2O4) show a more negative magnetoresistance compared with that of pure polyaniline (PANI). These results suggest that the interaction between the polymer matrix PANI and zinc nanoparticles take place
in these nanocomposites. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 120: 2856-2862, 2011″
“PURPOSE: To evaluate the anatomic location of the haptic and optic of single-piece sulcus-fixated intraocular lenses (IOLs) and their proximity to the iris and ciliary body using ultrasound biomicroscopy (UBM).
SETTING: Iladevi Cataract & IOL Research Center, Ahmedabad, India.
METHODS: This retrospective study comprised eyes that had primary sulcus GNS-1480 order selleck compound implantation of a single-piece IOL. Eyes had an intact anterior capsulorhexis that could provide uniform IOL support and a preoperative anterior chamber depth (ACD) greater than 2.7 mm. The fixation site of the haptics, distance between the optic edge and iris, optic tilt, anterior chamber angle (ACA), central ACD, and ciliary body edema were evaluated by UBM.
RESULTS: The time from surgery to UBM examination was 7 to 85 months. Both haptics were in the sulcus in 7 of the 10 eyes, 1 haptic was abutting the iris and the other was in the sulcus in 2
eyes, and both haptics were embedded in ciliary body in 1 eye. The mean distance between the optic edge and iris was 0.16 mm +/- 0.07 (SD), 0.15 +/- 0.03 mm, Nirogacestat solubility dmso and 0.38 mm, respectively. The mean ACA was 40.2 +/- 4.5 degrees (range 30.9 to 45.2 degrees), 34.1 +/- 4.5 degrees, and 44.1 degrees, respectively. The mean
ACD was 3.47 +/- 0.24 mm, 3.50 +/- 0.23 mm, and 3.57 mm, respectively. No eye had optic tilt or ciliary body edema.
CONCLUSIONS: Implantation of both haptics in the sulcus was not achieved in all eyes. The haptics and optics remained in close proximity to the posterior iris surface.”
“The purpose of the present research work was to extract linseed mucilage, use it as a mucoadhesive agent and to develop mucoadhesive microspheres for buccal delivery with an intention to avoid hepatic first-pass metabolism, by enhancing residence time in the buccal cavity. Linseed mucilage was extracted and used to prepare microspheres with varying concentrations of mucilage from formulation F1-F4 (1-2.5%) by spray-drying technique. The microspheres were evaluated for the yield, particle size, incorporation efficiency, swelling property, in vitro mucoadhesion, in vitro drug release, histological study, and stability. Microspheres were characterized by differential scanning colorimetry, scanning electron microscopy, and X-ray diffraction study. Further, the bioavailability study using the New Zealand rabbits was carried out. Formulation F4 showed the maximum mucoadhesion 89.37 +/- 1.35%, 92.10 +/- 1.37% incorporation efficiency, highest swelling index 0.770 +/- 1.23.
