A dose-sensitive modifier of the of Drosophila melanogaster ectopic eye
Walter de Gruyter GmbH - - 2013
С. А. Копыл, L. V. Omelyanchuk
AbstractEctopic eyes induced in a wing serve as a system for studying developmental plasticity in Drosophila. We used a set of chromosome deficiencies covering the second chromosome to ask whether there are dose-sensitive modifiers of the process. We identified three overlapping deletions showing the enlargement of ectopic eyes. The study of the genes localized in the region of interest suggests t... hiện toàn bộ
Immunodominant semen proteins I: New patterns of sperm proteins related to female immune infertility
Walter de Gruyter GmbH - - 2013
Andrea Brázdová, Martina Vermachova, J. Zídková, Z Ulčová-Gallová, Gabriel Peltre
Abstract Infertility affects approximately 10% of couples at reproductive age. Semen constituents may be potential immunogenic structures for women. The aim of our work is to detect and identify sperm proteins interacting with serum IgG antibodies from women with fertility disorders. The biochemical characterization of sperm antigens was performed using one and two dimensional gel electrophoresis,... hiện toàn bộ
Hypothalamic response to leptin changes during a hormonally induced estrous cycle in rats
Walter de Gruyter GmbH - Tập 1 Số 2 - Trang 221-234 - 2006
Kajsa Sjöholm, Björn Carlsson, Lena Carlsson
Abstract The leptin system regulates body fat mass through a feedback loop between adipose tissue and the hypothalamus. To test if leptin responsiveness may be regulated we assayed hypothalamic response to leptin during the estrous cycle; when changes in food intake are known to occur. Immature rats were treated with pregnant mare’s serum gonadotropin (PMSG) to induce synchronized follicular devel... hiện toàn bộ
The action of CGRP and SP on cultured skin fibroblasts

Leucojum aestivum L. in vitro bulbs induction and acclimatization
Walter de Gruyter GmbH - - 2014
Agata Ptak
Abstract The effects of growth retardants (paclobutrazol and ancymidol), sucrose, GA3 (gibberellic acid) and physical state of the medium (solid and liquid — Rita® temporary immersion system) on in vitro induction of Leucojum aestivum bulbs and their acclimatization were studied. Paclobutrazol, regardless of the physical state of the medium, stimulated the formation of bulbs (99.3%). Under the inf... hiện toàn bộ
Gender-based differences in the effect of dietary cholesterol in rats
Walter de Gruyter GmbH - - 2012
M. Marounek, Z. Volek, E. Skřivanová, M. Czauderna
Abstract Male and female rats were fed diets supplemented with cholesterol and palm fat at 10 and 50 g/kg, respectively; serum, hepatic tissue and faeces were analysed. Cholesterol supplementation significantly increased serum and hepatic cholesterol both in male and female rats. Male and female rats fed the cholesterol-containing diet differed significantly in serum cholesterol concentration (2.4... hiện toàn bộ
In vivo effects of N/OFQ(1–13)NH2 and its structural analogue [ORN9]N/OFQ(1–13)NH2 on carrageenan-induced inflammation: rat-paw oedema and antioxidant status
Walter de Gruyter GmbH - Tập 4 Số 2 - Trang 170-178 - 2009
R Zamfirova, Elina Tsvetanova, Albena Alexandrova, Lubomir Petrov, Polina Mateeva, А. Павлова, Margarita Kirkova, S Todorov
Abstract The effects of nociceptin(1–13)NH2 (N/OFQ(1–13)NH2) and its structural analogue [Orn9]N/OFQ(1–13)NH2 on acute carrageenan (CG)-induced peripheral inflammation and paw antioxidant status were studied. CG was injected intraplantarly in the right hind paw of rats and the volume of the inflamed paw was measured each 30 min for a period of 4h. When administered simultaneously with CG, N/OFQ(1–... hiện toàn bộ
The effect of solvent extraction on antioxidant properties of apricot fruit
Walter de Gruyter GmbH - - 2011
Annamaria Leccese, Raffaella Viti, S. Bartolini
Abstract Two solvent extraction procedures were used to investigate the extraction efficiency in terms of total antioxidant capacity and total phenols in apricot fruit. Samples were either sequentially extracted with aqueous ethanol (ethanol/water 80% v/v) and tetrahydrofuran or directly extracted with tetrahydrofuran. Each extract was analyzed for total antioxidant capacity by the Trolox Equivale... hiện toàn bộ
In vitro organogenesis secondary metabolite production and heavy metal analysis in Swertia chirayita
Walter de Gruyter GmbH - Tập 9 Số 7 - Trang 686-698 - 2014
Vijay Kumar, Savitri Singh, Rajib Bandopadhyay, Madan Mohan Sharma, Swarniv Chandra
AbstractAn efficient protocol of plant regeneration through direct and indirect organogenesis in Swertia chirayita was developed. Explants cultured on Murashige and Skoog medium supplemented with 2,4-D (0.5 mg L−1) with combination of Kinetin (0.5 mg L−1) showed the highest frequency (84%) of callusing and 1.0mg L−1 6-benzyladenine (BA) in combination with (100 mg L−1) Adenine sulphate (Ads) + (0.... hiện toàn bộ
Variation in morphology of Teucrium polium aggr. populations in Bulgaria
Walter de Gruyter GmbH - Tập 5 Số 6 - Trang 880-887 - 2010
Dolja Pavlova, Magdalena V. Vasileva
Abstract The aim of this study was to investigate natural serpentine and non-serpentine populations of Teucrium polium aggr. and to document the differences in their morphological traits, as well as estimate which characters are most likely contributing to differentiation of the populations. Nine populations distributed both on and off serpentine soils were investigated, and 12 different morpholog... hiện toàn bộ
