Thermodynamic and structural insight into the underlying mechanisms of the phosphatidylcholine liposomes - casein associates co-assembly and functionality.

The combination of data obtained from isothermal mixing calorimetry and light scattering allowed us to reveal the relationships between the character of the interactions of casein (β-casein and sodium caseinate (SCN) particles) with phosphatidylcholine (PC) liposomes and their specific properties, such as, the hydrophilic-lipophilic balance of the surface properties, the size, and the architecture. The size distribution diagrams, obtained by dynamic light scattering for the particles of pure PC, β-casein and their complexes, indicated the involvement of both the protein and liposome particles in the complex formation at pH 5.5 and low ionic strength (0.

Structural and thermodynamic features of covalent conjugates of sodium caseinate with maltodextrins underlying their functionality.

The sodium caseinate (SCN)-maltodextrin (MD) covalent conjugates were prepared by a food-grade process involving the first step of the Maillard reaction. The covalent conjugates were prepared with different weight ratios of biopolymers (R(MD : SCN) = 0.4; 1; 2; 5) in the system using maltodextrins of strongly different dextrose equivalents (DE), i.

[A computing laboratory-clinical system in the screening of malignant tumors: study of the state of the antioxidant system and level of cellular proliferation markers among the population from the Chernobyl AES accident area].

The author bases and describes the computing laboratory and clinical system for screening groups at a higher risk for malignant neoplasms whose incidence is likely to increase due to irradiation. Two years after the disaster the detected group at a higher risk was 2-2.4 times larger than the control group among persons who received the total irradiation dose 5 rem and over as well as among persons who are to be removed from the area polluted with radionuclides whatever the dose.

[The late results of the combined treatment of kidney cancer patients].

Randomized study with inclusion of certain types of immunotherapy in the schedule of complex treatment was conducted in 89 patients with kidney carcinoma after the operation. In 63 patients the tumor was in stage T3N0M0. The patients were separated into 4 groups after the operation.

[The importance of a sequence of laboratory diagnostic micromethods in detecting tumors in subjects with complaints of functional disorders of the gastrointestinal tract].

The paper is concerned with the diagnostic value of a complex of laboratory micromethods for detection of tumors which were used in 421 subjects who had been endoscopically examined for gastrointestinal discomfort. The methods assured correct diagnosis in 61.1% and gave false-positive results in 35.
