The biomass of Aspergillus flavus was modified by calcium chloride to achieve a bioadsorbent for treating nickel, cobalt, and zinc ions from aqueous solutions. The information of pH, bioadsorbent dose, contact time, and temperature effect on the removal efficiency are presented. The data of Freundlich and Langmuir isotherm and pseudo-first-order and pseudo-second-order kinetic models are also d...

cobalt (ii) chloride was used as a precursor to prepare co 3 o 4 nanotubes in reverse micelles. tween 80 was added as surfactant. the products were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy. the diameter of co 3 o 4 nanotubes was about 58 nm and the average length of them was around 261 nm. the study provides a simple and e...

Tungsten trioxide (WO(3)) nanostructures were synthesized by hydrothermal method using sodium tungstate (Na(2)WO(4).2H(2)O) alone as starting material, and sodium tungstate in presence of ferrous ammonium sulfate [(NH(4))(2)Fe(SO(4))(2).6H(2)O] or cobalt chloride (CoCl(2).6H(2)O) as structure-directing agents. Orthorhombic WO(3) having a rectangular slab-like morphology was obtained when Na(2)W...

In the title compound, [CoCl(C(12)H(8)N(2))(H(2)O)(3)]Cl·H(2)O, the Co(II) ion is coordinated by two N atoms from the 1,10-phenanthroline ligand [Co-N = 2.125 (6) and 2.146 (6) Å], one chloride ligand [Co-Cl = 2.459 (2)Å] and three water mol-ecules [Co-O = 2.070 (5)-2.105 (5)Å] in a distorted octa-hedral geometry. Inter-molecular O-H⋯Cl and O-H⋯O hydrogen bonds form an extensive three-dimension...

A simple and efficient method has been developed for the synthesis of alpha-aminonitriles by a one-pot three- component condensation of aldehydes, amines, and potassium cyanide in acetonitrile in the presence of a catalytic amount of CoCl2 at room temperature.

The cranial lateral line canal system of teleost fishes is morphologically diverse and is characterized by four patterns. One of these, widened lateral line canals, has evolved convergently in a wide range of teleosts, including the Lake Malawi peacock cichlids (Aulonocara), and has been attributed to its role in prey detection. The ability to study Aulonocara in the laboratory provides an oppo...

BACKGROUND Surveillance on common allergens identified by patch testing plays an important role in emerging allergen detection, which leads to both individual and societal level prevention. OBJECTIVE To study the changes in the pattern of contact sensitization and to identify risk factors associated with allergens. METHOD The data of 206 patients who underwent patch testing at King Chulalon...

The various cobalt(II) complexes were synthesized and characterized using tris-(2-benzimidazolylmethyl)amine (ntb) as a ligand where the ntb plays as a tripodal tetradentate ligand to form complexes with a trigonal pyramidal geometry. The complexes have 5 and 6 coordinate cobalt(II) ions depending on the additional ligand used. In each complex the additional ligand, chloride anion, or acetate a...

The retinoic acid receptor-related orphan receptor alpha (RORalpha) is critically involved in many physiological functions in several organs. We find that the main RORalpha isoform in the mouse liver is the RORalpha4 isoform, in terms of both mRNA and protein levels, while the RORalpha1 isoform is less abundant. Because hypoxia is a major feature of liver physiology and pathology, we examined t...

Human endogenous retroviruses (ERV) are an integral part of our genome. Expression of ERV is usually switched off but reactivation of ERV has been observed in varying human diseases including cancer. Recently, reactivation of ERV associated promoters in Hodgkin's lymphoma (HL) cells has been described. Despite relatively good prognosis, not all patients with HL can be cured with the established...
