Dimitrios Sgouros, Alexander Katoulis, Dimitrios Rigopoulos
INTRODUCTION: Corticosteroids are the mainstay of treatment for the acute phase of atopic dermatitis (AD), whereas topical emollients are mainly used for maintenance of remission. A topical agent that combines emollient and anti-inflammatory properties would achieve control of all phases of AD, without the need for chronic corticosteroid use. AIM: To assess the efficacy of a novel topical agent containing superoxide dismutase (SOD) 100 000 IU and 4% of a combination of plant extracts (blackcurrant seed oil, sunflower oil concentrate, balloon vine extract)...

In this paper, we focused on the development of nanostructured lipid carriers (NLCs) for dermal application. The NLC matrix was designed as a protective reservoir of biological active compounds that naturally occur in domestic fruit seed oils. Over the years, emulsions, as a popular physicochemical form of personal care products, were refined in order to obtain the best possible penetration into the skin of any bioactive compound introduced in the formulation, such as polyunsaturated fatty acids (PUFAs). In fact, the bioactive components are useful only if they are able to penetrate the skin unchanged...

A novel method for the UHPLC-MS/MS analysis of (E)-4-hydroxynonenal (4-HNE) is described. The method is based on derivatization of 4-HNE with pentafluorophenylhydrazine (1) or 4-trifluoromethylphenylhydrazine (2) in acetonitrile in the presence of trifluoroacetic acid as catalyst at room temperature and allows complete analysis of one sample of vegetable oil in only 21 min, including sample preparation and chromatography. The method involving hydrazine 1, implemented in an ion trap instrument with analysis of the transition m/z 337→154 showed LOD=10...

PURPOSE: It was hypothesised that blackcurrant seed oil beneficially modulates metabolic disorders related to obesity and its complications. The study also aimed to investigate the potentially adverse effects of an unbalanced diet on the distal intestine. METHODS: Male Wistar rats were randomly assigned to four groups of eight animals each and were fed a basal or obesogenic (high in fat and low in fibre) diet that contained either rapeseed oil (Canola) or blackcurrant seed oil...

Currant seeds, a by-product of juice production, are recognized as a valuable source of oil rich in polyunsaturated fatty acids. We have evaluated 28 currant varieties for their oil content and fatty-acid composition. The oil content in the seeds ranged from 18.2-27.7%, and no statistical difference between varieties of different fruit color were recorded. Furthermore, the estimated oil yields in the field production ranged from 26.4-212.4 kg/ha. The GC and GC/MS chemical profiles of the seed oils extracted from all examined varieties were common for currants...

Fatty acid methyl esters (FAMEs) were analysed by reversed-phase HPLC coupled with atmospheric pressure chemical ionisation (APCI) mass spectrometry. The chromatographic separations of the FAMEs were optimised using acetonitrile or binary acetonitrile gradients and C18 or C30 columns. The gas-phase reactions of acetonitrile and unsaturated FAMEs in the APCI source provided [M+C(3)H(5)N](+·) adducts. When fragmented, these adducts yielded diagnostic ions, allowing the unambiguous localisation of double bonds...

BACKGROUND: The present increased incidence of atopic diseases has been associated with an altered intake of essential fatty acids (EFAs). The composition of blackcurrant seed oil (BCSO) corresponds to the recommended dietary intake of EFAs, and as a dietary supplement could, in small doses, modify the imbalance of EFAs in an efficient way. OBJECTIVE: To assess the effect of dietary supplementation with BCSO on the prevalence of atopy at 12 months of age. METHODS: Three hundred and thirteen pregnant mothers were randomly assigned to receive BCSO (151) or olive oil as placebo (162)...

Gamma-linolenic acid (gamma-linolenic acid, GLA; C18:3 Delta(6, 9, 12)) belongs to the omega-6 family and exists primarily in several plant oils, such as evening primrose oil, blackcurrant oil, and borage oil. Delta(6)-desaturase is a key enzyme involved in the synthesis of GLA. There have been no previous reports on the genes encoding Delta(6)-desaturase in blackcurrant (Ribes nigrum L.). In this research, five nearly identical copies of Delta(6)-desaturase gene-like sequences, named RnD8A, RnD8B, RnD6C, RnD6D, and RnD6E, were isolated from blackcurrant...

Synopsis This report utilizes a new procedure based on epidermal stripping to analyse unlabelled skin fatty acids. This technique was applied to the study of human dry skin treated with blackcurrant seed oil, an essential fatty acid rich lipid also containing gamma linolenic acid. In human dry skin the usual fatty acids were found in the stratum corneum as in normal skin outer layers. Among the saturated series no significant difference was observed in the C16 chain but a smaller quantity of C18:0 was detected...

Gamma-linolenic acid (Gla) and oils containing Gla have evident positive effects on a variety of disorders, and therefore, the structure of triacylglycerols (TAGs) containing Gla is of special interest. The regioisomeric structures of TAGs 18:3(n-3)/18:2/18:2 (Ala/L/L) and 18:3(n-6)/18:2/18:2 (Gla/L/L) in blackcurrant seed oil were determined by Ag-HPLC/APCI-MS and Ag-HPLC/ESI-MS/MS techniques. In the latter, silver ion adducts were prepared by adding silver nitrate to the postcolumn flow. A new Ag-HPLC solvent system containing nonchlorinated solvents for the separation of Gla- and Ala-containing TAGs is introduced...

Blackcurrant (Ribes nigrum) seed oil is rich in alpha- and gamma-linolenic acids, the latter in particular being of potential use in medicine. The enzymatic hydrolysis of the oil was carried out in supercritical carbon dioxide using lipase Lipozyme as catalyst and changes in the composition of acylglycerols were recorded. Mono-, di-, and triacylglycerols and free fatty acids were separated by non-aqueous high-performance liquid chromatography in reversed phase mode and detected by UV diode array and 1H NMR detectors...

Herbal antirheumatics are indicated in painful inflammatory and degenerative rheumatic diseases. Their mechanism of action is broader than that of synthetic antirheumatics. Particular preparations from Devils's Claw with 50 to 100 mg of harpagoside in the daily dosage as well as a particular willow bark extract with 120 to 240 mg salicin in the daily dosage proved efficacy in a number of clinical studies including confirmatory ones. Exploratory studies indicate that these herbal antirheumatics were not inferior to the selective COX-2 inhibitor rofecoxib when treating acute exacerbations of chronic low back pain...

The fatty acid composition and total fatty acid content of seeds from 36 blackcurrant genotypes developed at the Scottish Crop Research Institute were examined. A rapid small-scale procedure, involving homogenization of seeds in toluene followed by sodium methoxide transesterification and gas chromatography, was used. There was considerable variation between genotypes. The gamma-linolenic acid content generally varied from 11 to 19% of the total fatty acids, but three genotypes had higher values of 22-24%, levels previously not reported for blackcurrant seed and similar to those for borage seed...

Thirty-six adult severe head injury and cerebral stroke patients in four intensive-care units were randomized to receive one of three enteral diets for 21 days. These diets, which supplied 45% of calories from fat, differed only in lipid composition. Diet A was comprised of 100% soybean oil, diet B contained a 50:50 (wt/wt) mixture of soybean oil and medium-chain triglycerides (MCTs), and diet C contained 42.5% MCT, 50% soybean oil, and 7.5% blackcurrant seed oils. Plasma phosphatidylcholine and fatty acid composition of plasma total phospholipids were determined before initiating treatment (day 0) and weekly throughout the study...

In this study, dietary supplements of blackcurrant seed oil (BCO) rich in the n-6 polyunsaturated fatty acid (PUFA) gamma-linolenic acid were fed to both RA patients and healthy volunteers with sunflower seed oil being fed to control subjects. A significant improvement in morning stiffness was noted in the RA patients receiving BCO. Monocytes were isolated from all subjects and cultured in the presence of lipopolysaccharide. It was observed that the production from the cultured monocytes of the cytokines IL-1 beta, TNF alpha and IL-6 as well as the prostaglandin PGE2 was markedly altered in those subjects given BCO...
