The electronic spectra of chloroformic acid ClCOOH and formic acid HCOOH are computed in large-scale multireference configuration interaction (MRD-CI) calculations. The computed spectrum of formic acid is in reasonable agreement with prior calculations and experimental data. The first electronic transition of ClCOOH is computed at 6.41 eV (193.4 nm), about 0.5 eV higher than in HCOOH. Together ...

The phytochemicals present in the plants are responsible for the biological activities and therapeutic properties of the various medicinal plants. They function as antioxidants in health promotion by preventing oxidant-damage which is the main cause of many diseases. The present study deals with the comparative analysis of phytochemicals in the methanolic and chloroformic leaf extracts of three...

OBJECTIVE There are few therapeutic options for treatment of multidrug resistant Klebsiella pneumoniae isolates as a hospital infectious agent (nosocomial infection). The aim of this study was to evaluate the antibacterial activity of Zataria multiflora Boiss extracts against ESBL-producing Klebsiella pneumoniae strains. MATERIALS AND METHODS This study was conducted on 100 K. pneumoniae isola...

candida species are the most common cause of opportunistic fungal infection worldwide. due to increasing resistance of fungi against conventional drugs, as well as their side effects, alternative natural products have become a renewed interest. in the current study, the anti-candida activities of scrophularia striata extract were examined. in this experimental study, microdilution assay and wel...
