bachground: toxic plants are an important reason for poisoning. the responsible plants are variable in different geographic spots. some areas such as lorestan province have more variety in herbal plants because of geographic condition. because of high poisoning incidence with toxic plants and mushroom, we assessed the incidence of poisoning with mushroom and toxic plants (tattore and ricinus co...

Previous studies have shown that indigenous beetle diversity reflects indigenous plant diversity in modified and remnant habitats. This study examines the indigenous: introduced relationship at a locality where degraded pasture has been progressively revegetated. Pitfall traps were used to collect beetles from three revegetated sites of different ages (5, 17 and 100 years) and in a coastal Mueh...

By means of a Q-banding technique, virtually every chromosome in two heteroploid mouse cell lines, RAG and MSWBS, has been identified. The origin of 60 to 80% of the chromosomes has been established; the remaining chromo somes can be identified as markers characteristic of the cell line. The extent of chromosome heterogeneity has been ex amined and compared in these two mouse tumor cell lines. ...

WHAT THIS ARTICLE IS ABOUT The subtribe Flaveriinae (Asteraceae: Helenieae) includes a number of plant species sometimes called yellowtops, glowworts, and false broomweed. Different species of this subtribe differ in their chemical pathways involved in photosynthesis. Somes species use a system known as C 3 photosynthesis, some use a system known as C 4 photosynthesis, and others display charac...

In order to cause Parkinson's Disease, the level of toxic exposure usually has to be either acute or chronic. Mild exposure to some known toxic causes, such as carbon monoxide would have no noticeable effect. Some other potentially toxic causes of Parkinson's Disease, such as copper and manganese are actually beneficial to health in normal quantities, and can only cause Parkinson's Disease in v...

background: mentha species are widely used in traditional medicine mostly as anti-flatulence. nowadays, their usage as flavor and preservative in food, cosmetic and pharmaceutical industries has been developed. moreover, cytotoxic effects of some mentha species have been reported. objective: in this study, cytotoxic properties of mentha piperita, m. spicata, m. aquatica, m. crispa, m. pulegium ...

background: suicide is a problem worldwide and occupation is an important risk factor. in the last decade, 55 200 deaths in the us were attributed to occupational risk factors. objective: to determine if toxic metal exposure was associated with suicide risk among paducah gaseous diffusion plant (pgdp) workers. methods: we assembled a cohort of 6820 nuclear industry workers employed from 1952 to...

persist in both freshwater and marine systems. They range from organisms that form red and brown tides to cyanobacteria that turn lakes and ponds green (Figure 1) and red. The toxins (termed “cyanotoxins”) that these organisms produce are usually secondary metabolites, and are more numerically diverse than the organisms that produce them. Here we will focus on the use of molecular methods for d...
