antiviral agents, many patients face barriers to access. In our Advances in Hepatology column, Dr David E. Bernstein discusses factors that are restricting the use of these lifesaving therapies. A feature article by Drs Nicolas A. Villa and M. Edwyn Harrison describes the diagnosis, classification, and management of biliary strictures, a common complication of liver transplantation. Although bi...

6 Gastroenterology & Hepatology Volume 6, Issue 7, Supplement 10 July 2010 18 years of age and for travelers’ diarrhea caused by noninvasive strains of Escherichia coli in patients older than 12 years of age. Ongoing studies are currently investigating rifaximin in IBS. A recent phase IIb multicenter clinical trial found that rifaximin effectively provided relief of global IBS symptoms such as ...

Since in vitro pH-cycling models are widely used to study dental caries, they should allow evaluations of fluoride effect on early stages of caries development. Therefore, acid etching on enamel surface must be avoided, enabling surface microhardness (SMH) analysis. In the present study, the pH-cycling model originally described by Featherstone et al.9 (1986) was modified to preserve the enamel...

The actin-related protein (Arp) 2/3 complex plays a central role in assembly of actin networks. Because distinct actin-based structures mediate diverse processes, many proteins are likely to make spatially and temporally regulated interactions with the Arp2/3 complex. We have isolated a new activator, Abp1p, which associates tightly with the yeast Arp2/3 complex. Abp1p contains two acidic seque...

Jeju ground water, containing vanadium compounds, was shown to increase glutathione (GSH) levels as determined by a colorimetric assay and confocal microscopy. To investigate whether the effects of Jeju ground water on GSH were specifically mediated by vanadium compounds, human Chang liver cells were incubated for 10 passages in media containing deionized distilled water (DDW), Jeju ground wate...

Background : Pain is an unpleasant emotional experience that illustrates ongoing tissue damage. Excessive use of non-steroidal anti-inflammatory drugs can cause peptic ulcer to gastric mucosal damage and perforation. Indonesia contains the largest area mangrove forest in world. There are 45 species found one them Asiatic Mangrove (Rhizophora mucronata). This type easy find rich alkaloids flavon...

Objective: The present study is focusing on the role of surfactant in photogalvanic cells and how photons from sunlight can be used as a driving force for energy solar conversion storage. Methods: An H shaped cell was designed electrical output transformations. Electrical circuit proposed by using dye, reductant, surfactant, NaOH, double distilled water (DDW), multi-meter, calomel electrode, 25...

Felodipine is a calcium-channel blocker with low aqueous solubility and bioavailability. Lipid dosage forms are attractive delivery systems for such hydrophobic drug molecules. Nanoemulsion (NE) one of the popular methods that has been used to solve dispersibility problems many drugs. was formulated as NE utilizing oleic acid an oil phase, tween 80 60 surfactants ethanol co-surfactant. Eight fo...

A procedure for tailoring a blended wing-body con guration to reduce its computed wave drag is described. The method utilizes an iterative algorithm within the framework of rst-order linear theory. Four computed examples are included. In each case, the zero-lift wave drag was reduced without an increase in drag due to lift. Introduction In the initial rough-cut state of supersonic conguration d...
