Municipal and industrial wastewater contain a lot of contaminants. The major contaminants of concern are heavy metals. Heavy metals are known to be toxic, non-biodegradable and have a long half-life. The release of untreated wastewater containing heavy metals can cause serious problems to human, plants and animals. In this study, activated carbon was developed from sugarcane bagasse and its eff...

The local presence and concentration of metal ions in biological systems has been extensively studied ex vivo using fluorescent dyes. However, the detection of multiple metal ions in vivo remains a major challenge. We present a magnetic resonance imaging (MRI)-based method for noninvasive detection of specific ions that may be coexisting, using the tetrafluorinated derivative of the BAPTA (TF-B...

The effect of solvent conditions, including pH, on product ion spectra obtained from precursor ions produced by electrospray ionization (ESI) was examined. Bovine carbonic anhydrase 2 was used as a model protein and the product ions generated by collision induced dissociation of the whole protein were measured under several different solvent conditions (pH 5.0, 3.7, and 0.1% HCOOH (pH 2.6)/MeCN...

Ion channels are naturally occurring pores through the proteins that regulate the passage of ions and thus maintain the concentration of ions inside and outside the cell. The ion channels control many physiological functions and they can show selectivity for a specific ion. Ion channels are mostly observed in nerve cells and muscle cells. The influx of ions into cells can be regulated by a gate...

Background and aims: The removing of (potential) toxic heavy metal ions from sewage, especially in industrial and mining waste effluents, has been widely studied in recent years. The aim of present study was to investigate the various methods for lead removal of lead ions from industrial wastewater. Methods: This study was a review research. Data were collected through different databases in va...

One major cause of aquatic pollution is the accumulation heavy metal ions. This review aimed to examine application natural biofilm as biosorbent for Mg(II), Cr(VI), and Cu(II), an eco-friendly, economical, efficient remediation strategy. Biofilm matrices were collected from different freshwater ecosystems observe their biosorption properties. The compared EPM values biofilms showed a universal...

Ferritin is a major iron storage protein. In case of iron deficiency, serum ferritin levels play a critical role in diagnosis and treatment.[1] Serum ferritin is an acute phase protein. Serum ferritin level is an indicator of body iron stores and may be normal or elevated in infective, inflammatory, or malignant disease.[2] Iron ions will be precipitated on the enamel surface as thin acid-resis...

Platinum-based anti-cancer drugs form a major family of cancer chemotherapeutic agents. Cisplatin, the first member of the family, remains a potent anti-cancer drug and exhibits its clinical effect by inducing local DNA kinks and subsequently interfering with DNA metabolism. Although its mechanism is reasonably well understood, effects of intracellular ions on cisplatin activity are left to be ...

Magnesium ions play important roles in the structure and function of nucleic acids. Whereas the tertiary folding of RNA often requires magnesium ions binding to tight places where phosphates are clustered, the molecular basis of the interactions of magnesium ions with RNA helical regions is less well understood. We have refined the crystal structures of four decamer oligonucleotides, d(ACCGGCCG...

belladona leaves as well as all other studied leaves contains two distinct phosphatase fractions belonging respectively to types ii and iiii the major parts of these enzymes is extraetible by water. it was not possible to extract the non soluble fraction which is solidly retained by the cellular constituents. phosphatase ii does not differ from other phosphatnses of the same type. whereas phosp...
