The transcervical access for transcatheter aortic valve replacement.

Alternative accesses for transcatheter aortic valve replacement (TAVR) are needed in a certain number of patients, who present contraindications to the standard transfemoral access. We present the transcervical approach, which allows to access the aortic valve via supra-aortic vessels, namely, the brachiocephalic trunk, carotid artery, or subclavian artery. This approach is interesting because it avoids thoracotomy, which is necessary with some other alternative approaches for TAVR, such as the transaortic or transapical ones.

[Effect of lycopene on blood lipoproteids in women with type 2 diabetes mellitus in postmenopause].

Blind randomized placebo-control research included 39 women. The following criteria were: menopause period for more then 1 year long; diabetes mellitus; arterial hypertension; hypercholesterolemia. The patients were divided into two groups.

Preparation and Properties of Soluble Pig Skin Fractions Influencing on Human Keratinocyte Proliferation and Differentiation.

Three fractions with different molecular weights were isolated from pig skin. Fraction 1 (F1) and fraction 3 (F3) stimulated human keratinocyte proliferation in primary and regenerating cultures, but didn't affect their differentiation. Fraction 2 (F2) inhibited keratinocyte proliferation and stimulated their differentiation.

[Experimental validation of licopin-containing drug tomatol use in combined therapy of patients with diabetic retinopathy].

Effects of tomatol on metabolic changes in the blood and lacrimal fluid and ocular capillaries of rabbits with alloxane diabetes were studied. Tomatol is a drug containing licopin carotenoid characterized by a high biological activity. The intensity of lipid peroxidation was notably decreased, antioxidant activity of the blood increased, lipid metabolism parameters in the blood and some parameters of proteinase inhibitory balance in the blood and lacrimal fluid normalized in diabetic rabbits treated with tomatol in comparison with untreated rabbits.

[Experimental evaluation of the antibacterial activity of tomato pulp oil extract].

The antibacterial action of the oil extract obtained from tomato pulp has been studied with the use of museum strains Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 5638-P and Candida albicans ATCC 885-653, recommended for the determination of the antibacterial activity of medicinal preparations (State Pharmacopoeia, edition XI), as well as Enterobacter, Streptococcus, Staphylococcus, Klebsiella and Escherichia clinical strains. As revealed in this study, tomato pulp oil extract produces a wide-spectrum antibacterial effect on Gram-positive and Gram-negative microorganisms and on fungi of the genus Candida. The study has determined that this antibacterial action is linked with the presence of a complex of organic acids (succinic, citric, tartaric, etc.
