Analysis of polyphenols, phytosterols, and bitter principles in Teucrium L. species
Tập 7 - Trang 542-550 - 2012
Total polyphenols, tannins, β-sitosterol, and bitterness values were determined in native and cultivated populations of Teucrium L. species from Croatia (T. arduini L., T. botrys L., T. chamaedrys L., T. flavum L., T. montanum L., T. polium L., and T. scordium L. subsp. scordioides Schreb.). Teucrium species have long been present in folk medicine for diverse medicinal uses, but little is known ab......
Increased antidepressant-like effect of desipramine combined with central stimulants (caffeine and amphetamine) in mice
Tập 7 - Trang 391-396 - 2012
Desipramine is a widely used antidepressive agent that inhibits the reuptake of noradrenaline and serotonin, and central stimulants such as caffeine and amphetamine help to release noradrenaline and serotonin. This work aimed to evaluate whether the combination of these agents could produce a stronger antidepressant-like effect than either of the drugs alone. To this end, male mice were treated wi......
Micropropagation of Vitis vinifera L. cv. ‘Malagouzia’ and ‘Xinomavro’
Tập 5 - Trang 839-852 - 2010
The effects of six basal media on in vitro shoot proliferation of the greek grapevines Vitis vinifera L. cv. ‘Malagouzia’ and ‘Xinomavro’ were investigated. Galzy and Zlenco proved to be the most effective for ‘Malagouzia’ and ‘Xinomavro’, respectively. If only BA was present in the medium, shoot development was poor and the plantlets were chlorotic. When the medium was supplemented with BA and NA......
Distribution and characterization of Aegilops and Triticum species from the Bulgarian Black Sea coast
Tập 1 - Trang 399-411 - 2006
A total of 158 Aegilops-Triticum samples representing six Aegilops species (one diploid, four tetraploid and one hexaploid) and one diploid Triticum were collected along the Bulgarian Black Sea coast, and their distribution on the 350 km long coastal line was reported. The region south of Kamchia river, accepted as the middle point of the coast, was characterized by the greatest diversity of these......
Distinctive attributes for predicted secondary structures at terminal sequences of non-classically secreted proteins from proteobacteria
Tập 3 - Trang 320-326 - 2008
C- and N-terminal sequences (64 amino acid residues each) of 89 non-classically secreted type I, type III and type IV proteins (Swiss-Prot/TrEMBL) from proteobacteria were transformed into predicted secondary structures. Multivariate analysis of variance (MANOVA) confirmed the significance of location (C- or N-termini) and secretion type as essential factors in respect of quantitative representati......
Total phenolic content and antioxidant activity of plants used in traditional Romanian herbal medicine
Tập 6 - Trang 388-396 - 2011
A number of herbal plants from Romania widely used as natural food additives or for health promotion in traditional medicine were investigated for their antioxidant activity. Methanol extracts were obtained from plants belonging to the Lamiaceae family (lavender Lavandula angustifolia L.; lemon balm Melissa officinalis; sage Salvia officinalis; oregano Origanum vulgare L.; rosemary Rosmarinus offi......
Frequency of lactase persistence genotype in a healthy Polish population
Tập 6 - Trang 176-179 - 2011
The majority of mammals are unable to digest lactose due to post-weaning deactivation of the LCT gene, which is responsible for encoding the enzyme lactase (i.e., adult-type hypolactasia). A substitution of C with T at position −13910 bp upstream of the LCT gene has been linked to the lactase persistence phenotype in European populations. We investigated the frequency of LCT-13910C>T polymorphism ......
The impact of local spatial resistance on the movement behaviour of Tenebrio molitor L.
- 2006
Although the impact of vegetation and other environmental factors on the distribution of terrestrial invertebrates has been known since the 1950s, basic knowledge about their interaction with micro-landscape elements is lacking. In experimental model systems, the impact of varying local spatial resistance (LSR) on the distribution of Tenebrio molitor individuals was analysed in the laboratory. In ......
The effect of anastrozol on spatial memory in adult rats
Tập 4 - Trang 186-189 - 2009
Androgens are known to affect cognitive functions via organizational and activational effects. It is unknown whether the effects are mediated via the androgen receptor or after conversion to estradiol with aromatase via estrogen receptors. The aim of our study was to find out whether testosterone affects spatial memory directly or through its metabolite estradiol. Rats were treated with testostero......
Age and growth in a newly-established invasive population of topmouth gudgeon
Tập 5 - Trang 256-261 - 2010
Specimens of invasive topmouth gudgeon, Pseudorasbora parva, from Šúr Pond (Bratislava, Slovakia) were examined to assess age and growth, and to determine whether this recently-established invasive population employs a less specialized ontogenetic trajectory than the specialized form typical of native and/or long-time established populations. Samples were collected in October 2004 (n=143). Standar......
