abstract nowadays, soil pollution with heavy metals has become a major problem which their accumulation in plants can directly or indirectly influence on animals and humans life. lead and cadmium are poisonous metals, with increasing the amount of these metals in environmental pollution; they will be increased in food chain significantly. in this research, three levels of cadmium (0, 100 and 20...

lead is a relatively ubiquitous heavy metal with particular features such as resistance to corrosion, high malleability and wide variety of industrial applications. in medicine, however, it is considered as a slow-acting toxic substance affecting multiple body systems, specifically functioning as a potent neurotoxin in the central nervous system. lead poisoning may be acute or chronic and can b...

The antimicrobial action of a number of non-antibiotic drugs has been demonstrated in recent years, for example the antimycobacterial activity associated with the phenothiazine neuroleptic class. However, as with other classes of non-antibiotics, such activity may be traced back to common precursor structures such as the phenothiazinium dye, methylene blue. While the rising tide of antimicrobia...

background and objective: nowadays, the presence of extended-spectrum β-lactamases (esbls) producing strains in serratia genus causes the emergence of resistance to many antibiotics. so, the lack of proper diagnosis of esbls strains can lead to failure in the treatment. the objective of the present study was to investigate esbls production in serratia strains isolated from the clinical blood sa...

When standard leads or ordinary prncordial leads are taken with a string galvanometer electro-cardiograph, the resistance of the patient can be measured for each lead. However, no method has been described previously by which the resistance at any of the extremities or at any point on the body can be measured. A method for doing this is described below. Principle. When the standard leads are ta...
