BACKGROUND Escherichia coli occurs naturally in the human gut; however, certain strains that can cause infections, are becoming resistant to antibiotics. Multidrug-resistant E. coli that produce extended-spectrum beta lactamases (ESBLs), such as the CTX-M enzymes, have emerged within the community setting as an important cause of urinary tract infections (UTIs) and bloodstream infections may be...

Baltic seaweeds were used to obtain aqueous extracts (E) through changing initial pH of deionised water added to algal biomass (EpH3·H2O, EpH7·H2O, and EpH10·H2O) and through changing pH of the mixture of algae and deionised water (EpH3, EpH7, and EpH10). Algal extracts were characterized in terms of the concentration of polyphenols and micro- and macroelements. The highest concentration of pol...

Maca (Lepidium meyenii Walpers) is a plant cultivated in central Peru, and its root is a common active ingredient in the botanical dietary supplements for its effects on a variety of health issues such as sexual dysfunction, anemia, and cancer. The plant contains compounds that have cytotoxic and antioxidant activities, but information on the metabolism of the bioactive compounds is limited. Th...

We report on the experiments on orientation of a migratory songbird, the garden warbler (Sylvia borin), during the autumn migration period on the Courish Spit, Eastern Baltics. Birds in experimental cages, deprived of visual information, showed the seasonally appropriate direction of intended flight with respect to the magnetic meridian. Weak radiofrequency (RF) magnetic field (190 nT at 1.4 MH...

There are several ecological and industrial uses that summarized this paper. The emerging evidence revealed Unani school medicine, seeds leaves plant might be us...

Phytoextraction of mercury-contaminated soils is a new strategy that consists of using the higher plants to make the soil contaminant nontoxic. The main problem that occurs during the process is the low solubility and bioavailability of mercury in soil. Therefore, some soil amendments can be used to increase the efficiency of the Hg phytoextraction process. The aim of the investigation was to u...

otostegia persica (burm.) boiss. is the medicinal plant of lamiaceae family that has long been used traditionally in treatment of severe diarrhea, common cold, flatulence, headache, sore, fever, skin allergies, and blood fat and sugar. this research was conducted in 2013 for one year to identify some ecological characteristics and potential allelopathicof o. persica in hormozgan province. the c...

The knowledge of flavonoids involved in plant-plant interactions and their mechanisms of action are poor and, moreover, the structural characteristics required for these biological activities are scarcely known. The objective of this work was to study the possible in vitro phytotoxic effects of 27 flavonoids on the germination and early radical growth of Raphanus sativus L. and Lepidium sativum...
