Abstract The influence of cobalt, copper, iron(III), manganese and zinc nitrate salts on phase transitions thermal stability ammonium (AN) has been studied discussed. Differential analysis/differential scanning calorimetry coupled with thermogravimetry mass spectrometry were used to evaluate the analyzed systems. Each salt was appropriately mixed create samples AN:salt ratios 4:1, 9:1 49:1. It ...

Thirty-eight metal salts were tested for their capacity to enhance transformation of Syrian hamster embryo cells by a simian adenovirus, SA7. All of the metal salts with known carcinogenic potential in animals or mutagenic activity in microbial or mammalian cells increased the SA7 transformation frequency. Metals were classified into three groups according to the concentration necessary to prod...

Culture growth and recombinant protein yield of the Pichia pastoris GS115 methanol utilization positive system were studied in response to the types and levels of metals present in the growth medium and the supplemental salts typically used for these fermentations. Magnesium and zinc were both required to support cell growth but at significantly reduced levels compared to the control. However, ...

soil reduces the hazardous effects of compounds on the components of ecosystem because of self –purification property and the ability for their fixation. playing such a role in soils under redox conditions is performed by pedogenic fe-mn concentrations. in order to investigate cobalt, copper and lead accumulation in iron and manganese concentrations, at first the concentrations were precisely s...

Keratinocyte proliferation and migration are essential for the reconstruction of the cutaneous barrier after skin injury. Interestingly, thermal waters which are rich in trace elements (e.g. boron and manganese), are known to be able to improve wound healing. In order to understand the mechanism of action of this effect, our study investigated the in vitro modulation of keratinocyte migration a...

In this work, a comparison of the blood biochemical and mineral profile of anestrus buffaloes with those of regular cyclic animals was made. There was significant reduction (P<0.01) in the total cholesterol and phosphorus levels in anestrus state. However, blood glucose, HDLcholesterol, triglycerides, calcium, copper, cobalt, manganese and zinc levels did not differ between anetrus and regular ...
