In the present study, aqueous solutions of some copper-complexing ligands were screened for their cytotoxicity using brine shrimp lethality test. Among the ligands tested, diacetyl-bis(N4-methylthiosemicarbazones) (ATSM) proved to be the most safe and non-toxic compound (2% lethality at 10 ppm), while pyruvaldehyde Bis(N4-methyl)thiosemicarbazone (P...

Research on covictims, family members, and close friends who have lost loved ones to intimate partner homicide (IPH) is a neglected area of study. We conducted phenomenological interviews with covictims to gain insights into risk and lethality, examined affidavits from criminal case files, and reviewed news releases. The data uncovered acute risk factors prior to the homicide, identified change...

background: the present study compared lethal concentrations (lc50-96 h) of cdcl2, crcl3, and pb (no3)2 between two scaled and scaleless freshwater fish species: cyprinus carpio (cyprinidae) and pangasius hypophthalmus (pangasiidae). methods: the experimental fishes were obtained from fish markets/ponds with average lengths and weights of approximately 11.68 ±1.92 and 9.8±1.9 cm, and 25.92±6.3 ...

background and objectives: phlomis olivieri benth. (lamiaceae) is a medicinal plant widely distributed in iran. in the present study, we have investigated the phytochemical constituents, antioxidant activity and general toxicity potential of the aerial parts of this species. methods: silica gel (normal and reversed phases) and sephadex lh-20 column chromatographies were used for isolation of co...

There is a good deal of research showing that suicide attempts increase markedly during adolescence. This study aims at studying the demographic and clinical variables of adolescent suicide attempters and comparing certain potential risk factors between adolescent and adult suicide attempters. It was found that adolescents in our study sample differ significantly from adults in the levels of de...

Essential genes are defined by their requirement to sustain life in cells or whole organisms. The systematic identification of essential gene sets not only allows insights into the fundamental building blocks of life, but may also provide novel therapeutic targets in oncology. The discovery of essential genes has been tightly linked to the development and deployment of various screening technol...

background: currently available radioprotectors are poorly tolerated in man and the general use of aminothiols is compromised by their side effects. this study was carried out to test and compare the radioprotective potential of cimetidine and famotidine against lethally gamma irradiated nmri mice. materials and methods: adult male nmri mice in groups of 10 were exposed to various doses of gamm...

purpose: in recent years high explosive bomb attacks have been increasingly directed against   civil structures by various terrorist organizations. this paper describes a numerical method for   assessing the interaction of high explosive air blast within the complex geometrical type of a   congested urban environment.   materials and methods: the first step in predicting blast effects on a targ...
