acriflavine (3,6-diaminoacridine) is an anticeptic drug developed in 1912. previous research has focused on investigation of the intercalating features of acriflavine, but little is known about its interaction with proteins. drug-receptor interaction is of major interest in clinical science. the aim of the present study was to evaluate the ability of acriflavine to induce alterations in conform...

a highly sensitive electrochemicalimmunosensor was developed to detect hcg based on immobilization ofhcg-antibody (anti-hcg) onto robust nanocomposite containing gr, chit,1-methyl-3-octyl imidazolium tetra fluoro borate ionic liquid (il)(gr-il-chit). aunps were used to immobilize hcg antibody on the modifiedelectrode. the amine groups of the antibody are covalently attached toaunps/gr-il-chit n...

metronidazole is used to treat trichomoniasis, bacterial vaginosis, and other diseases. there are controversy aspects about its teratogenicity. a teratogenic agent can alter morphology or subsequent function of the fetus. the aim of this study was to examine an alternative method for the recognition of the mechanism or the bimolecular potential changes in mice fetus caused by metronidazole usin...

background although magnetic resonance spectroscopy (mrs) has been shown as an effective diagnostic tool in distinguishing inflammation from neoplasm in cystic brain lesions, the optimum approach in selecting the portions of lesions in mrs and the possible effects of different times of echoes (tes) remains unknown. objectives to determine the most effective te in diagnosing neoplastic lesions b...

cobalt is one of the most important constituent present in ceramic industries. glazers are the relevant workers when they are producing blue colored ceramic, causing occupational exposure to such metal. through this study, urinary cobalt was determined in glazers in a ceramic industry when they were producing blue-colored ceramic glazes.in this case-control study, spot urine samples were collec...

background soil pollution due to toxic metals released by industrial activities such as cement production is a serious problem from the standpoints of the environment and public health, because they tend to persist, circulating indefinitely and, eventually, accumulating throughout the food chain. objectives this paper presents the results of the first research study into the distribution of cad...

evaluation of pre-fixed biological tissues preparation methods for atr-ftir biospectroscopy fourier transform infrared (ftir) spectroscopy in atr (attenuated total reflection) mode is a powerful tool for studying biomedical samples, which can provide important structural information on the molecular composition. currently, formalin fixation and paraffin preservation (ffpp) is the preferred source ...

lithum can be de termined both by atomic absorption spectroscopy andflame emission spectroscopy. we have used the later method with a zeiss model pmqli spectro photometer fitt ed with ante-chamber atomizer and a potensiome rric line recorder. accurate ana lysis for the clement was acco mplished due to a sophisracared measuring instrument.
