An even more embarrassing situation is Gillette’s foamy shaving cream‚ a natural fit with the razor business. S. C Johnson and Sons Edge Gel have supplanted that brand as the leading seller. These experiences created frustration at Gillette. Despite its preeminence in razors and blades‚ the company has been unable to sustain a leading position across the full range of toiletries.

seven out of ten silicone-gel breast implants scanned by researchers had developed a leak. The US Food and Drug Administration (FDA) study could reawaken the debate over the safety of breast implants. Many women claim that leaking silicone-gel has sparked serious illness‚ including chronic autoimmune disease. The FDA team used MRI scans too look at 344 women with implants. They found that 69% had a least one ruptured implant. And in 21%‚ the silicone gel contained within the implant

X – 9l August 15‚ 2012 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using agar-water gel test. The agar-water gel set up was composed of a petri dish of agar-water gel containing three wells. Drops of potassium permanganate (KMnO4)‚ potassium dichromate (K2Cr2O7) and methylene blue(C16H18N3SCl) were simultaneously introduced to each well. Methylene blue‚ having the largest molecular

Gel electrophoresis was carried out according to buffer system discussed by [11]. Complisation of electrophoresis gel was processed for activity of proteases detection by gel X-ray film contact print method (GXCP) [12]. After electrophoresis gel was incubated in 0.1M Glycine-NaOH buffer pH 9 for 7 to 8min then was placed on X-ray film [Padul‚ M.V. et al.‚ 2012]. The gel was removed from X-ray film after 45min depending on the extent

This was shown through our SDS-PAGE gel (figure 7). The gel showed that our LDH sample matched that of standard #1. We were able to determine that this first standard was the heart muscle LDH isozyme‚ by comparing the pH of the gel (pH 9) to the pI of the isozyme‚ 5.5 (heart) and 8.7 (skeletal muscle). Since we know these charges‚ and the rule that when a pH is greater than pI it will
