Colorimetric test-systems for creatinine detection based on composite molecularly imprinted polymer membranes.

An easy-to-use colorimetric test-system for the efficient detection of creatinine in aqueous samples was developed. The test-system is based on composite molecularly imprinted polymer (MIP) membranes with artificial receptor sites capable of creatinine recognition. A thin MIP layer was created on the surface of microfiltration polyvinylidene fluoride (PVDF) membranes using method of photo-initiated grafting polymerization.

[Sensor system based on molecular-imprinted polymer membranes for the selective recognition of aflatoxin B1].

lymer membranes, synthesized using acrylamide as a functional monomer, were characterized by sufficient mechanical stability and high adsorbtion capability towards aflatoxin B1. The molecularly-imprinted polymer membranes were characterized by the pronounced imprinting effect as well as by insignificant adsorbtion of aflatoxins B2 and G2. Therefore, the synthetic analogues of bioreceptors able to individual recognition of aflatoxin B1 were obtained and used as a basis for the optical sensor system for aflatoxin B1 detection in a concentration range 1-500 ng/ml.

[Aflatoxin-selective molecularly-imprinted polymer membranes based on acrylate-polyurethane semi-interpenetrating polymer networks].

Synthetic analogs of biological receptors able to group-selective recognition of aflatoxins were obtained using the combination of the technique of molecular imprinting with the method of computer modeling. The synthetic receptors were obtained in a form of thin and porous membranes based on semi-interpenetrating polymer networks. The selection of functional monomers able to noncovalent interactions with aflatoxins B1, B2, and G2 was based on the data of computer modeling.

[The microwave therapy of patients with duodenal peptic ulcer who took part in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station].

With the purpose of increasing effectiveness of therapy and preventive treatment of those patients having been in the zone of the Chernobyl accident, microwave resonance therapy (MRT) was tried in a multiple-modality treatment of this patient population. There were 36 male patients with a mean age of 37.7 years.
