Measurement of Water Activity by Electronic Sensors AnalyticalChemistry

Wed, 16 May 2012 12:46:43 GMT

Water activity of foods is an important thermodynamic property affecting stability with respect to physical, chemical and microbiological changes. Water activity, aw, is the ratio of the vapor pressure of water in a system, Pw sy, to the vapor pressure of pure water, Pv w, at the same temperature. It is equal to the equilibrium relative humidity ERH established in the surrounding air. Thus Several instruments based on electronic sensors are commercially available for direct determination of...

Sulfonylureas AnimalModels

Wed, 16 May 2012 04:47:34 GMT

For nearly 50 years, sulfonylureas, derived from sulfonic acid and urea, have had a central role in oral hypoglycemic therapy of T2DM. Sulfonylureas increase endogenous insulin secretion and can only be used in individuals that have retained significant b-cell function. The combination of efficacy, low incidence of adverse events, and low cost has contributed to their success and continued use. Sulfonylureas are generally safe and are relatively inexpensive. Hypoglycemia is the most common...

As with any other chemical peeling procedure, the art and science of TCA chemical peels is dependent on the proper peeling technique. TCA is a versatile peeling agent and depending on its concentration, can be used for superficial, medium, or deep chemical peels. However, the cleaning and peeling technique is essentially the same for each depth. In general for the superficial peels patients do not require any sedation however, for medium-depth peels, a mild sedative such as diazepam 5-10 mg...

The properties of the brain endothelium forming the BBB are important considerations when designing drugs to target or avoid the brain. Molecular traffic across the BBB is regulated by a combination of physical, transport, and metabolic barrier properties. Tight junctions restrict the paracellular pathway, and endothelial membrane lipids and other components determine the passive pathway across the cells. Specific uptake transport proteins and vesicular transcytotic mechanisms mediate the...

It is now clear that both mitochondria and peroxisomes in mammals have the complete enzymatic machinery to P-oxidise unsaturated fatty acids at rates dependent on the chain length of the fatty acids and the number and configuration of the double bonds. Most unsaturated fatty acids are oxidized in peroxisomes faster than their saturated counterparts, with the exception being...

Throughout the industrialized world, the population is becoming older. It is predicted that the percentage of persons over age 65 will rise further, while that of persons under age 15 will fall. Aging is a biological process with a characteristic temporal course. Senescence refers to the physical changes associated with aging. It is still unclear whether human aging is specifically genetically predetermined or, alternatively, reflects cumulative damage incurred over time. The cellular...

Rest Seats ToothStructure

Mon, 23 Apr 2012 14:45:21 GMT

An adequate amount of tooth structure must be removed to allow for a minimum metal thickness of 1 mm in the area of an occlusal rest seat. To achieve adequate reduction, some operators prepare a rest seat in the tooth before starting the retainer preparation. They then use 1-mm reduction grooves to ensure adequate thickness. Although this approach can work well, problems may occur if it becomes necessary to alter the position of the rest seat during the laboratory phase. Preference therefore...

Methods of detection Clostridium perfringens FoodSafety

Early methods relied on the rapid formation of a 'stormy clot' reaction in milk, but this is not necessarily definitive and is easily mis-read. Agar or liquid media containing sulphite and iron salts are commonly used to detect clostridia by formation of black precipitates, but are not sufficiently specific for Cl. perfringens. Liquid iron-sulphite containing media may be used in Most Probable Number MPN techniques. Since the organism does not readily form spores in laboratory media, heating...

All the methods considered up to this point share a common element. They optimize a fitness function which comprises a set of weighted components. The effect is to turn the multiobjective problem into a single-objective optimization. There are a number of issues with this approach. The weights need to be defined empirically and may need to be varied from problem to problem. Whilst normalization of the properties may help this may in itself be nontrivial for certain properties.

Consequences of Stereoselectivity in Drug Metabolism for Metabolic Toxification DrugMetabolism

Thu, 12 Apr 2012 13:05:16 GMT

Enzymes are chiral and interact with their substrates stereoselectively and enantioselectively. Enantioselective toxification has been shown for nitrogen mustard-derived cytostatic drugs, such as cyclophosphamide and ifosfamide. Also, metabolic toxification of procarcinogens often proceeds with high stereoselectivity. A striking example is the toxification pathway of benzo a pyrene, which ultimately leads to the potent genotoxic metabolite 7,8-dihydrodiol-9,10-epoxide see Figure 3 . Four chiral...
