Background and aims: Tooth decay is one of the most common chronic diseases around the world and this problem is the result of variety of different bacteria. Streptococcus mutants is one of the most important bacteria which is related to this disease. Finding new effective antibacterial agents is an important area in bioscience for fighting and controlling bacterial infections. Essential oils a...

The aqueous extracts (15 micrograms ml-1 medium) of 22 plants used in folkloric medicine in Palestine were investigated for their antifungal activity and minimum inhibitory concentrations (MICs) against nine isolates of Microsporum canis, Trichophyton mentagrophytes and Trichophyton violaceum. The extract of the different plant species reduced colony growth of the three dermatophytes by 36 to 1...

Article history: Received on: 24/11/2015 Revised on: 10/12/2015 Accepted on: 28/12/2015 Available online: 27/02/2016 A reversed-phase high-performance liquid chromatographic method using photodiode array detector with gradient elution has been developed and validated for the simultaneous estimation of ascorbic acid, free phenolic acids and flavonoids (catechin, rutin, quercetin, myrecetin, apig...

Sonchus arvensis, known as sowthistle, belongs to Asteraceae and contains numerous phenolic acids flavonoids that exhibit antioxidants. The type of extraction solvent will affect biological activity level, resulting in different metabolite profiles metabolomics approaches can evaluate by fingerprint analysis using FTIR spectrophotometry UHPLC-Q-Orbitrap HRMS. Furthermore, the spectra profile HR...

O April 28, 1996, in the historic Tasmanian penal colony of Port Arthur, a lone gunman killed thirty-five persons with a semiautomatic rifle. Following that incident, which was the largest of a series of mass homicides, the federal and state governments of Australia agreed on a broad plan of gun control, implemented over the following twelve months. The new controls included prohibitions on cer...

A dose dependent enhancement of memory was observed with A. racemosus and C. pluricaulis treatment as compared to control group when tested on second day. A. racemosus and C. pluricaulis at the dose of 200 mg/kg, po showed significantly higher percent retentions, than piracetam. Multiple treatment with A. racemosus and C. pluricaulis for three days also demonstrated significant dose dependent i...

The inoculum sources of phytoplasmas associated with carrot severe yellowing and reddening symptoms were investigated in Ankara Konya provinces, Turkey. presence 16SrVI 16SrI-related the seeds seven cultivars that are widely cultivated regions, as well weeds fields, was determined this study. Sequence analysis confirmed existing phytoplasma groups samples by using conventional molecular methods...

The increasing world population and developing industrial areas increase the need for energy. This situation makes alternative renewable energy sources efficient use of these more valuable. In this study, seeds Sinapis arvensis, Brassica nigra, napus from Brassicaceae family grown in ecological conditions Bayburt province Turkey, to determine usability potential wild species biodiesel productio...
