611 results about "Drug tolerance" patented technology

Drug tolerance is a pharmacological concept describing subjects' reduced reaction to a drug following its repeated use. Increasing its dosage may re-amplify the drug's effects; however, this may accelerate tolerance, further reducing the drug's effects. Drug tolerance is indicative of drug use but is not necessarily associated with drug dependence or addiction. The process of tolerance development is reversible (e.g., through a drug holiday) and can involve both physiological factors and psychological factors.

Use of nano structured lipid carrier drug feeding system

The invention discloses an application of nanometer structure lipid carrier administration system in the antineoplastic drug to reverse the multiple-drug tolerance of tumour cell, which comprises the following parts: solid lipid material, liquid lipid material and antineoplastic drug, wherein the rate of the liquid lipid (such as oleic acid) is 0-30wt%; the solid lipid is selected from monoglyceride; the liquid lipid is oleic acid; the antineoplastic drug is Paclitaxel or adriablastina. The invention has highly effective cell uptaking and cytolymph condensing function with packing molecular target in the antineoplastic drug of cell, which avoids P-glucoprotein in the drug tolerant cytolymph from identifying the antineoplastic drug to reduce exclusion.

Device for harvesting bacterial colony and method therefor

When multiple kinds of bacterial colonies are present in a petri dish and, for example, a drug tolerance is to be measured, harvesting of mixed colonies of different types of bacteria makes it impossible to accurately determine the drug tolerance. Also, it is required to improve the throughput of a device for harvesting a bacterial colony. From images illuminated from multiple directions, isolating bacterial colonies are automatically extracted. Next, the image feature amounts are calculated from the multiple images that are illuminated from multiple directions and colonies are grouped depending on the feature amounts. Then, bacterial colonies to be harvested are determined based on the results of the grouping.
