    ISOLASI SILIKA (SiO ) DARI AMPAS TEBU (BA GA SSE) SEBAGAI BAHAN DASAR NATRIUM SILIKAT (Na 2 2 SiO ) UNTUK INHIBITOR KOROSI PADA BESI 3

    No full text
    Sintesis senyawa natrium silikat (Na 2 SiO ) sebagai inhibitor telah berhasil dilakukan menggunakan silika (SiO 2 3 ) yang berasal dari ampas tebu sebagai precursor. Silika dipisahkan menggunakan metode isolasi. Metode yang digunakan pada penentuan laju korosi ialah kehilangan berat. Senyawa natrium silikat dapat menghambat laju korosi dengan efisiensi inhibisi sebesar 59,58% pada medium asam klorida (HCl), 43,86% pada medium air laboratorium kimia FMIPA dan 63,53% pada medium garam. Kata Kunci : Natural silika, bagasse, besi, inhibitor, mediu

    Albumin.

    No full text
    <p>Albumin immunoreactivity (brown stain) at P14 (a-b) and P28 in controls (c-d) and IHH (e-f). Note positive immunoreactivity for albumin in both experiment groups at P14 and several spots of albumin immunoreactivity in the cortex and thalamus of the IHH animal at P28. Albumin is present in intracellular vesicles in neuroependymal cells in the ventricles (b & d). (g) The sum of positive scores for albumin leakage in the neuropil of the respective brain areas are presented as fractions of the maximum possible score in each experiment group at P28. (a, c & e): scale bar = 2 mm (b, d & f): scale bar = 50 μm at x400 magnification. Abbreviations: IHH, intermittent hyperoxia-hypoxia; P14, postnatal day 14; P28, postnatal day 28. </p

    <p>(a-d): H&E retinal slices from control (a) and IHH animals at P14 (b-d) showing haemorrhage in the ganglion cell layer (b), inner nuclear layer (c) and outer nuclear cell layer (d). (e-h): Retinal wholemounts stained with endothelial-specific Biotinylated <i>Griffonia</i> (<i>Bandeiraea</i>) <i>Simplicifolia</i> Lectin I Isolectin B4 from controls at P28 with a mature vascular bed (e) and no vasculature extending beyond the ora serrata (f). Retinal vascular bed in IHH animal at P28 with less remodelling (g) and areas of vascularization beyond the ora serrata (h). (a-d): x400 magnification; scale bar = 50 μm. (e-h): x100 magnification; scale bar = 200 μm. Abbreviations, IHH, intermittent hyperoxia-hypoxia; P14, postnatal day 14; P28, postnatal day 28.</p

    Vascular density.

    <p>(a) Vascular density as % of controls (white columns, n = 4) in IHH animals at P14 (grey columns; IHH: n = 10) and P28 (black columns; IHH: n = 12). Data are expressed as mean ± 95% confidence intervals. (b-e) x400 magnification of lectin-stained endothelium in IHH (upper row) and control (lower row) at P14 (b & d) and P28 (c & e). *<i>p</i> = 0.005 IHH vs. control. Scale bar = 50 μm. Abbreviations: IHH, intermittent hyperoxia-hypoxia; P14, postnatal day 14; P28, postnatal day 28; pvwm, periventricular white matter. </p

    <p>T<sub>2</sub>-relaxation time in the brain at P14 in litter A (grey columns, n = 13), litter B (black columns, n = 9) and C (white columns, n = 8) in the cortex (a), hippocampus (b), putamen (c) and thalamus (d). T<sub>2</sub>-relaxation times are shown in milliseconds. Differences between litters are marked where significant (<i>p</i> < 0.05). Data are presented as mean ± 95% confidence interval. Abbreviations: IHH, intermittent hyperoxia-hypoxia; P14: postnatal day 14; P28: postnatal day 28. </p

    <p>Fractional anisotropy (a); mean (b), radial (c) and axial diffusivity (d) in white matter areas of litter A (grey columns, n = 13), B (black columns, n = 9) and controls (white columns, n = 8) on postnatal day 14. Mean, axial and radial diffusivity are shown in units of mm<sup>2</sup>/s. Data are presented as mean ± 95% confidence interval. Differences between litters are marked where significant (<i>p</i> < 0.05).
