Amine-based volatile compounds released bymicroorganisms offer an alternative diagnostic approach for the identification of foodborne pathogens. Our objective has been to solvent cast cellulose acetatemembranes to immobilise dyes and to use the resultant membranes as a plastic device to discriminate between different types of amines (triethylamine, isobutylamine, isopentylamine). The plastic de...

In the present work, photocatalytic activity of pristine Cu2SnS3 (CTS) and a composite with graphene oxide (GO), i.e., CTS + GO, prepared by precipitation technique, its utilization as catalyst for degradation Navy Blue (NB) ME2RL reactive azo dye were studied. The structural, morphological, optical properties synthesized evaluated. dyes was used to evaluate GO under visible light irradiation. ...

Azo dyes are widely used in textile, printing, cosmetic, drug and food-processing industries. They are also used extensively in laboratories as either biological stains or pH indicators. The extent of such use is related to the degree of industrialization. Since intestinal cancer is more common in highly industrialized countries, a possible connection may exist between the increase in the numbe...

The susceptibility of 12 strains of Mobiluncus curtisii and 10 strains of M. mulieris to 23 antimicrobial agents and 15 other compounds was determined. All strains were susceptible to chloramphenicol, clindamycin, rifampin, tobramycin, vancomycin, virginiamycin, and all beta-lactam antibiotics tested, including imipenem. One strain of M. mulieris was resistant to erythromycin and josamycin. All...

Atherosclerotic plaques that undergo rapid progression to stenosis are responsible of stroke or acute coronary syndrome. The vulnerability of the atherosclerotic plaque may be enhanced due to the presence of microcalcifications. Our aim was to analyze microcalcifications on epoxy resin-embedded semithin sections from bioptic samples of carotid endarterectomies. An original trichromic method con...

Candida albicans is one of the most common pathogen causes fungal infections. This opportunistic pathogen can form biofilms comprised of yeast, hyphae and pseudo hyphal elements, and the hyphal form C. albicans considered as probable virulence factor. We investigated the antibiofilm activities of 13 quinones and anthraquinones related compounds against C. albicans biofilms by using crystal viol...

cobitis keyvani is recently described from the sourhern caspian sea basin. limited information is available about morphological features of c. keyvani , therefore this study was conducted to provide osteological characteristics and cranial myology of this species. for this purpose, nine specimens of c. keyvani were collected from the talar river. the specimens were cleared and stained with aliz...

Quantitative studies of complex formation from the determination of stability constants of the binary complexes of metal (II)/(III)alizarin and also the mixed complexes of metal (II)/(III)alizarin-NTA have been described using paper electrophoretic technique. The stability constant of metal-(II)/(III)-alizarin are found to be 105.14, 104.84, 104.44 and 104.14 and mixed complexes of metal (II)/(...
