Experimental and theoretical study of the effect of temperature on collagen in aqueous solution

Background and Objectives: An experimental andtheoretical study ofthe effect oftemperature onthe vibrational spectra of an aqueous collagen solution in the range of 60–90°C was carried out.

Polymorphism manifestations and aqueous environment influence on the physico-chemical properties of modified succinic acid

Background and Objectives: Succinic acid is widely used in medicine, in particular, in the treatment of cardiological, neurological and endocrinological diseases. An urgent task of pharmacology is to increase the degree of bioavailability and solubility of drugs. One of ways to increase the therapeutic effect of drugs is the development of their polymorphic modifications, which contribute to a more pronounced therapeutic effect.
