[Oxidative stress in focal symptomatic and cryptogenic epilepsy in young patients].

Objective: To study oxidative stress in young patients with focal symptomatic and cryptogenic epilepsy and after the new-onset epileptic seizures.

Material And Methods: Patients, aged from 19 to 44 years, were distributed into three groups, 30 patients in each: patients after a few (first) epileptic seizures, patients in the clinical remission that has lasted at least one year, and patients with treatment-resistant epileptic seizures. The control group included 20 healthy people.

Effect of Morphogenetic Protein BMP-2 on X-Ray Density of Bone Defect in the Experiment.

In experiments on Wistar rats, a simulated defect in the flat bones of the skull was filled with a collagen sponge of animal origin impregnated with BMP-2 or pure sponge; in control rats, the defect was left open. During follow-up, X-ray density of the collagen sponge in the experimental groups differed significantly. The results attest to the absence of spontaneous remodeling of the bone tissue under conditions modeled focal defect.

Lipoic acid nanoforms based on phosphatidylcholine: production and characteristics.

We describe the dynamics of lipoic acid (LA) alone, incorporated in liposomes and as a part of nanoemulsions. Mass spectrometry shows that LA in water forms aggregates of two or three molecules in the form of a negatively charged ion and a neutral molecule. Phosphatidylcholine (PC)-based nanoforms of LA as liposomes and nanoemulsions with a particle size equal to 145 nm are characterized by a high degree of incorporation of LA into the nanoparticles and long-term stability during storage at room temperature.

Improved Anticancer Effect of Recombinant Protein izTRAIL Combined with Sorafenib and Peptide iRGD.

One of the main problems in oncology is the development of drugs that cause the death of cancer cells without damaging normal cells. Another key problem to be solved is to suppress the drug resistance of cancer cells. The third important issue is to provide effective penetration of drug molecules to cancer cells.
