Optimization of the extraction process of polyphenols from Thymus serpyllum L. herb using maceration, heat- and ultrasound-assisted techniques
(Elsevier, 2017)
Despite the fact that Thymus serpyllum is well-known medicinal plant and its chemical profile and biological activity have been investigated, there is no detailed study regarding the influence of different techniques and ...
Research on Chemical Composition and Biological Properties Including Antiquorum Sensing Activity of Angelica pancicii Vandas Aerial Parts and Roots
(American Chemical Society (ACS), 2017)
The essential oil, different extracts, and isolated compounds of Angelica pancicii Vandas (Apiaceae) were investigated for the first time. The GC-FID and GC-MS analyses revealed sesquiterpenoids as the main constituents ...
Comparative Analysis of Phenolic Compounds in Seven Hypericum Species and Their Antioxidant Properties
(Natural Product Incorporation, 2017)
A comparative analysis of the phenolic compounds in the 70% EtOH extracts of Hypericum acutum, H. androsaemum, H. barbatum, H hirsutum, H maculatum, and H richeri has been carried out using high-performance liquid ...
The effect of meteorological and chemical parameters on summer phytoplankton assemblages in an urban recreational lake
(EDP Sciences, 2017)
The summer phytoplankton community was studied across both vertical and temporal scales in relation to environmental factors in the shallowrecreational Sava Lake. The sampling was conducted weekly at four depths from ...
Corticosterone oscillations during mania induction in the lateral hypothalamic kindled rat-Experimental observations and mathematical modeling
(Public Library of Science (PLoS), 2017)
Changes in the hypothalamic-pituitary-adrenal (HPA) axis activity constitute a key component of bipolar mania, but the extent and nature of these alterations are not fully understood. We use here the lateral hypothalamic-kindled ...
Novel hexamethylene diamine-functionalized macroporous copolymer for chromium removal from aqueous solutions
(Wiley, Hoboken, 2017)
Macroporous copolymers of poly[(glycidyl methacrylate)-co-(ethylene glycol dimethacrylate)] (PGME) with various crosslinker (ethylene glycol dimethacrylate) concentrations and porosity parameters and additionally functionalized ...
Metabolomics study of Populus type propolis
(Elsevier, 2017)
Herein, we propose rapid and simple spectroscopic methods to determine the chemical composition of propolis derived from various Populus species using a metabolomics approach. In order to correlate variability in Populus ...
Persistent organic pollutants (POPs) in sediments from river and artificial lakes in Serbia
(Elsevier, 2017)
In an attempt to evaluate the toxicological condition of the most important river and artificial lakes in Serbia, 52 grab-samples were collected from different locations. Sediment samples were analyzed for PCBs (PCB 28, ...
Testing of intergranular and pitting corrosion in sensitized welded joints of austenitic stainless steel
(Serbia : Association of Metallurgical Engineers of Serbia, 2017)
Pitting corrosion resistance and intergranular corrosion of the austenitic stainless steel X5Cr Ni18-10 were tested on the base metal, heat affected zone and weld metal. Testing of pitting corrosion was performed by the ...
Tunable invisibility cloaking by using isolated graphene-coated nanowires and dimers
(England : Nature Publishing Group, 2017)
We investigate, both theoretically and numerically, a graphene-coated nano-cylinder illuminated by a plane electromagnetic wave in the far-infrared range of frequencies. We have derived an analytical formula that enables ...
