Influence of different pre-treatment methods on isolation of extracts with strong antibacterial activity from lichen Usnea barbata using carbon dioxide as a solvent
(Elsevier, Amsterdam, 2013)
Multiplication and spreading of multiresistant pathogenic bacteria that cause fatal infections in humans and animals have boosted research on implementation of newer technologies for producing natural substances with strong ...
Effect of four lichen acids isolated from Hypogymnia physodes on viability of rat thymocytes
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Four lichen acids, physodalic acid (F1), physodic acid (F2), 3-hydroxyphysodic acid (F3), and isophysodic acid (F4), were isolated from Hypogymnia physodes methanol extract using preparative reversed-phase high performance ...
Dynamics of beryllium-7 specific activity in relation to meteorological variables, tropopause height, teleconnection indices and sunspot number
(Elsevier, Amsterdam, 2017)
The dynamics of the beryllium-7 specific activity in surface air over 1987-2011 is analyzed using wavelet transform (WT) analysis and time -dependent detrended moving average (tdDMA) method, WT analysis gives four periodicities ...
Cadmium and mercury accumulation in European hare (Lepus europaeus): age-dependent relationships in renal and hepatic tissue
(Springer Heidelberg, Heidelberg, 2014)
A total of 63 European hares have been collected from five Serbian agricultural regions. The hares assayed were divided into four age groups (3-6 months, 12 months, 12-24 months, and 24-36 months) and investigated upon ...
Leaves of higher plants as biomonitors of radionuclides (Cs-137, K-40, Pb-210 and Be-7) in urban air
(Springer Heidelberg, Heidelberg, 2013)
Leaves of linden (Tilia tomentosa L. and Tilia cordata Mill.) and horse chestnut (Aesculus hippocastanum L.) were analysed as biomonitors of radionuclides in urban air. Samples of soils, leaves and aerosols were collected ...

DNA-binding and DNA-protecting activities of small natural organic molecules and food extracts
(Elsevier Ireland Ltd, Clare, 2020)
The review summarizes literature data on the DNA-binding, DNA-protecting and DNA-damaging activities of a range of natural human endogenous and exogenous compounds. Small natural organic molecules bind DNA in a site-specific ...
Premature centromere division of the X chromosome in neurons in Alzheimer s disease
(Wiley-Blackwell, Malden, 2008)
Premature centromere division (PCD) represents a loss of control over the sequential separation and segregation of chromosome centromeres. Although first described in aging women, PCD on the X chromosome (PCD,X) is markedly ...
