Rats that receive intravenous injections of sodium iodate develop a retinopathy characterized by the partial loss of the retinal pigment epithelium (RPE). In thin sections examined by transmission electron microscopy the choriocapillaris atrophied adjacent to areas of RPE destruction. The endothelial cells thickened and lost their fenestrae and the lumen of(More)
BACKGROUND Solid acid catalyst was prepared from Kraft lignin by chemical activation with phosphoric acid, pyrolysis and sulfuric acid. This catalyst had high acid density as characterized by scanning electron microscope (SEM), energy-dispersive x-ray spectrometry (EDX) and Brunauer, Emmett, and Teller (BET) method analyses. It was further used to catalyze(More)
Vascular casts were made of the choriocapillaris (CC) of rabbits that received sodium iodate intravenously 6-28 days prior to examination, in order to augment studies of CC regeneration in sectioned material. Regeneration of CC was evident 6 days after administration of iodate where zones of spared CC bordered zones of atrophic CC. Venular as well as(More)
Solvolysis of oil palm empty fruit bunches (EFB) fibres using different solvents (acetone, ethylene glycol (EG), ethanol, water and toluene) were carried out using an autoclave at 275°C for 60 min. The solvent efficiency in term of conversion yield was found to be: EG>water>ethanol>acetone>toluene. The liquid products and residue obtained were analyzed(More)
The rabbit and rat choriocapillaris atrophies in response to experimental destruction of the retinal pigment epithelium by intravenous injection of sodium iodate. This provides a convenient model of capillary atrophy. We have observed that pericytes are spared during this process; the atrophy is due to loss of endothelium only. Extensive examination of thin(More)
A Kenaf fibers supported transition metal oxide solid acid catalyst (SAC) was prepared by wet impregnation method followed by calcination at 700°C. The characterizations of catalyst were studied by various methods. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Energy dispersive spectrometer (EDX) showed that tungsten oxide particle(More)
Correction We found an important error in our published paper [1]. On page 7, Section: One-step conversion of Jatropha oil to biodiesel, line 3, we wrote a reaction temperature of 120degreesC. The correct temperature should be 220degreesC. The pressure was also omitted from the same reaction description and should be 7.1 MPa. Direct production of biodiesel(More)
