In the synthesis of organic phosphorus compounds by the plant and in their storage in the seed as reserve food the inorganic phosphates play an important part. The phosphorus used in this synthetic process is taken into the plant in inorganic form and used in the building up of complex organic phosphorus compounds such as lecithins, phosphoand nucleo-prot,eins and salts of phytic acid. It is be...

As we enter the era of bio-nanotechnology, nanomaterials are playing a new and important role in many biology-related applications and advanced nanodevices. In particular, those conjugated with biological moieties have enormous potential in biolabeling, drug delivery, and therapeutic applications. In fact, much progress has been achieved in the past ten years based on inorganic (e.g., CdSe, Au)...

The toxic effects of arsenicals are significantly modified by numerous biological and abiotic factors. The toxicity of arsenic in the environment is affected by temperature, pH, Eh, organic content, phosphate concentration, adsorption to solid matrices, the presence of other substances and toxicants, duration of exposure and the arsenic species present. In general, inorganic arsenicals are more...

Spiders are one of the most intriguing groups of venomous animals. Substances found in their venom vary from simple inorganic compounds to large multi-domain proteins. In this article, we review some of the latest work presenting active principles that add to the known spider toxin universe. Two aspects of novelty are addressed in particular, structural (novel types of molecules in terms of str...

Variation of hydrochemical conditions, with special reference to adequacy of waters as fish habitats, was traced based on selected hydrochemical parameters obtained during the studies conducted from February 2013 till February 2014 year. The results were compared with earlier studies. The sources of organic pollution were identified, and the effect of biogenic substances on the biomass, as well...

Identification of inorganic substances in the lung is an important step towards the establishment of a cause and effect relationship in the study of pneumoconiosis. The conventional methods for this identification usually require an ashing which makes it difficult to study the localisation of these substances in relation to pathology. A method is described to identify foreign substances in the ...
