Objective High concentration of iron and other trace elements could restrict bacterial growth and modify their metabolic pattern as well. However, this study aimed to find out the influence of iron, chromium, cadmium and synergism or antagonism between these elements on the growth of a gram positive bacterium. Materials and Methods In a series of experiments, Bucillus cereus was cultured in a n...

the core sediment samples were analysed for grain size, carbonates (caco3), organic carbon (oc) to obtain a preliminary view of its environmental conditions near point calimere along the southeast coast of vedaranyam, india.the high concentration of sand in the core is attributed to the tidal influence at the akkarapallivasal river mouth. the sea water which enters the river suspends the floccu...

background foods are enriched with variety of chemical elements. some of these elements are necessary for human health. these elements enter in liquid, the cells and other organs, certain amount of these elements are essential for body organs to work properly. objectives this research was conducted to compare the level of lead and cadmium contamination in garlic species planted in ramhormoz and...

the possible relationships between trace elements, oxidative stress and subclinical ketosis during the transition period were evaluated in dairy cows. blood samples were obtained by jugular venipuncture at four times of the transition period: 3 weeks and 1 week before and 1 week and 3 weeks after calving. the highest concentrations of malondialdehyde (mda) and betahydroxybutyrate (bhb) were obs...

INTRODUCTION Accumulation of trace elements occurs in conditions of decreased kidney function. In some conditions, increased trace elements can have toxic features. On the other hand, studies are showing that concentration of some trace elements could be decreased in ERSD patients as well. The most important factor affecting trace element concentration in ERSD patients is the degree of renal fa...

Background: In addition to gas pollutants, many chemicals and air pollutants are in the form of particulate matter. Particulate matter consists of a complex mixture of variable sized particles and physicochemical composition. These particles mainly contain minerals including Fe, Al, Ca, K, Cu, Ti, Mn, Ni, V and their size, chemical composition and concentration are important to assess ...

The comparative study of the chemical elements’ concentration (mainly heavy metals) in the breast milk of 57 women and of the development of perinatal and neonatal pathology in their newborns is conducted. In newborns were diagnosed the following diseases: bronchitis, pneumonia, respiratory distress syndrome, aspiration syndrome, conjugated jaundice, edema syndrome, hemorrhagic syndrome, congen...

The study was aimed to evaluate the influence of the vascular disease, atherosclerotic obliterans (AO), on the location and concentration of elements in the arterial wall and serum. Use of a modern method for studying element's concentration and distribution in samples of clinical material, i.e. laser ablation inductively coupled plasma mass spectrometry, is presented. Elements are not equally ...
