Efficacy of Biologically Active Food Supplements for People with Atherosclerotic Vascular Changes.

The current paper deals with the development of a new biologically active food supplement (BAFS) aimed at treating atherosclerosis. Since atherosclerosis is considered to be a disease of aging, the composition of the supplement includes such essential minerals as magnesium and potassium, which are commonly used to prevent atherosclerosis, as well as vitamins C, E and the B-group vitamins in order to address the needs of the elderly. The authors outline the supplement-manufacturing technology and discuss the clinical trial undertaken by patients, aged about 60 years, with peripheral atherosclerosis.

Updating the Chemiluminescence Oxygen-Aftereffect Method for Determining the Rate Constant of the Peroxy-Radical Self-Reaction: Oxidation of Cyclohexene.

Updating the facile chemiluminescence oxygen-aftereffect method, most suitable for determining the rate constant (k ) of the peroxy-radical self-reaction (main chemiluminescence channel), pertained to considering the sensitivity of such a method toward a disturbing influence of the peroxy radicals of the initiator of the chain oxidation process. Such a disturbance may derive from the side chemiluminescent reaction, which involves peroxy radicals of both hydrocarbon and initiator. To examine the applicability and limitations of the chemiluminescence method under present scrutiny, cyclohexene was used as the model oxidizable hydrocarbon substrate.

[Carotid endarterectomy and endovascular angioplasty with stenting in patients with atherosclerotic stenoses and occlusions of the internal carotid artery].

The authors made a comparative assessment of carotid endarterectomy and endovascular angioplasty with stenting in patients with atherosclerotic lesions of the carotid arteries. The authors consider that indications to stenting and carotid endarterectomy are identical in patients with stenose and occlusions of the carotid arteries. Contraindications to angioplasty of carotid arteries are determined.

Selective targeting of green fluorescent nanodiamond conjugates to mitochondria in HeLa cells.

Fluorescent cellular biomarkers play a prominent role in biosciences. Most of the available biomarkers have some drawbacks due to either physical and optical or cytotoxic properties. In view of this, we investigated the potential of green fluorescent nanodiamonds as biomarkers in living cells.

Phytosorbent prepared from sunflower seed husks prevents mercuric chloride accumulation in kidney and muscle of adult rabbits.

In the present study, the effect of a melanin-containing phytosorbent, "Victoria," on mercury accumulation in rabbits' tissues was studied. This phytosorbent is derived from black sunflower seed husks. Domestic rabbits were administered either one single nontoxic low-level dose of mercuric chloride (i.
