1. A method of obtaining a sodium salt of carboxymethyl amylum, including the processing of starch carboxymethyloxime agent monochloracetate sodium, the introduction of special additives, processing with an aqueous solution of hydroxide n the sodium in the reactor and mixing machine in the mode of intense shear forces and drying, characterized in that the number of working zones of the reactor and mixing machines in which they are provided intensive shear forces, equal to not less than three when the fill factor of the working zones of 0.5-0.8 at the shear rate 500-1500 with-1.2. The method according to claim 1, characterized in that as the target additives can be used a simple low molecular weight polyethers based on ethylene oxide or propylene oxide, polyethylene glycol, epichlorohydrin and its derivatives.3. The method according to claim 1, characterized in that prior to being fed into the reactor and mixing machine starch and carboxymethylcelluose agent are pre-mixed in a screw machine.4. The method according to claim 1, wherein when processing the reagents in the reactor and mixing machine, the temperature of the support in the range of 30-50°C.5. The method according to claim 1, characterized in that the starch used starch-containing product - flour of wheat, rye or barley.

Avocado seed starch can therefore be used in the synthesis of superabsorbent polymers.

For designing SPIONs based MRI probes, there are several important aspects that need to be considered: 1) stem cell uptake, this is a necessary prerequisite for the application of SPIONs for stem cell labeling; 2) relaxivity, this is directly related to the MRI probe sensitivity; 3) a long-term stay in cells, SPIONs-labeled cells should retain the label and remain viable by MR for weeks, even months because preclinical and clinical trials mostly will need a long-term follow-up of tissue function and the fate of labeled cells; and 4) biosafety, the formulations should be biocompatible to stem cells and the host without side effects on their biological properties and functions.

Avocado seed starch and carboxymethyl cellulose superabsorbent polymer:Synthesis and characterisation.

The WAC for the avocado seed starch blend was 39g/g (3900% of the original weight) when the ratio of the avocado starch, carboxymethyl cellulose and aluminium sulphate was 88: 9.7: 2.3 respectively.

The SAPs were characterized by water absorption capacity (WAC) tests, Fourier transform infrared spectroscopy analyses, solubility fraction tests, effects of crosslinker quantity and swelling rate were investigated to determine the suitability of avocado starch in the synthesis of SAPs.

EFFECT: use of the conjugate allows for increasing duration of the presence of the low-molecular substance in blood plasma.

SUBSTANCE: invention pertains to the method of obtaining modification products of phytogenous starch-containing raw materials, used for modifying formaldehyde-containing thermoreactive resins, widely used in industry. Description is given of the method of obtaining the modifier for synthetic thermoreactive formaldehyde-containing resins by oxidative modification of the starch-containing raw material in a water alkaline suspension, under aeration conditions of the reaction mixture, in the presence of a catalyst - metal ion and chemically active components, relative to the starch-containing material, chosen from a group which includes melamine, dicyandiamide, carbamide, toluenesulphamide, caprolactam, phenol, resorcin or their mixture, at 50-100°C until obtaining a free-flowing reaction mixture with viscosity of 20-60 cP measured using viscometer "ВЗ-6".

SUBSTANCE: invention concerns process of obtaining hydroxyl starch derivative which includes interaction of the reducing end of hydroxyalkyl starch represented by the formula (I), left unoxidised before this reaction, with a compound of formula (II) R'-NH-R", where R1 R2 and R3 independently denote hydrogen or linear or branched hydroxyalkyl group while R' or R" or R' and R" include at least one functional group X capable of interaction with at least one more compound before or after the reaction of (I) and (II). The invention also concerns hydroxyl starch derivative obtained in this process, and production process for hydroxyl starch derivative and polypeptide, a pharmaceutical composition incorporating the said hydroxyl starch derivatives.
