We report a cadmium- and lead-detecting transcriptional repressor from Mycobacterium tuberculosis designated CmtR. Two genes were co-transcribed with cmtR, one encoding a deduced P1 type ATPase. Purified CmtR bound to the cmt operator-promoter, and repression of transcription was lost after introduction of a stop codon into cmtR. Assays of metal-dependent expression from cmt and nmt operator-pr...

Two proteins have been implicated in the mannose 6-phosphate-dependent transport of lysosomal enzymes to lysosomes: the 300kDa cation-independent and the 46kDa cation-dependent mannose 6-phosphate receptors (CI- and CD-MPRs). The mammalian CI-MPR also mediates endocytosis and clearance of insulin-like growth factor II (IGF-II). Mutant mice that lack the CD-MPR are viable, mice that lack the CI-...

There is a growing need to develop technologies that can separate and selectively remove hazardous chemical species from waste effluents. Selective removal of cadmium ions through a supported liquid membrane (SLM) containing triethanolamine (TEA) as a mobile carrier has been studied. The effects of Cd(II) concentration, HCl in feed and carrier concentration in membrane has been studied. Cd(II) ...

A biosorbent was prepared by using wood apple shell (WAS) powder and studied its application for the removal of Cd(II) from aqueous solution by a batch method. The biosorbent was characterized by infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and elemental analysis. WAS is principally made up of lignin and cellulose, containing functional groups such as alcoholic, keton...

Collecting duct (CD) renin is stimulated by angiotensin (Ang) II, providing a pathway for Ang I generation and further conversion to Ang II. Ang II stimulates the epithelial sodium channel via the Ang II type 1 receptor and increases mineralocorticoid receptor activity attributed to increased aldosterone release. Our objective was to determine whether CD renin augmentation is mediated directly ...

A novel complex of cadmium (II) picrate (pic) with V-shaped ligand bis(N-allylbenzimidazol-2-ylmethyl)benzylamine (babb), with composition [Cd(babb)(2)](pic)(2), was synthesized and characterized by elemental analyses and electrical conductivity, IR, and UV/visible spectra. The crystal structure of the complex has been determined by the single-crystal X-ray diffraction. In the complex, the coor...

Abstract This study demonstrated that Moringa oleifera seed biomass (MOSB) has the potential to be used as a natural alternative in removal of lead (Pd), cadmium (Cd), and copper (Cu) from water which was justified by level toxicity, environmental unfriendliness, costly nature chemical coagulants presently used. The Fourier Transform Infrared (FTIR) analysis identify MOSB functional groups pres...

The title coordination polymer, {[Cd(C8H4O4)(C14H14N4)]·C3H7NO} n , was synthesized by solvothermal reaction of metallic cadmium with the semi-rigid neutral ligand 1,4-bis-[(1H-imidazol-1-yl)meth-yl]benzene (bix) and the V-shaped benzene-1,3-di-carb-oxy-lic acid (m-H2bdc). The structure exhibits a pseudo-C-centring which is almost fulfilled by the polymeric metal complex but not by the solvent ...

Background/Aim: There is no study comparing open esophagectomy (OE), video-assisted thoracic surgery (VATS), and robot-assisted minimally invasive (RAMIE) in a single institution. Patients Methods: This included 272 patients who underwent subtotal divided into three groups: OE (n=110), VATS (n=127), RAMIE (n=35) groups. Moreover, short-term outcomes were compared. Results: Overall complications...

Pyridine-2,4,6-tricarboxylic acid (ptcH(3)) reacts with Cd(II), Mn(II), Ni(II), Mg(II), Ca(II), Sr(II), Ba(II), Dy(III) salts forming different products depending on the reaction conditions. In the presence of pyridine at room temperature the acetate, chloride or nitrate salt of Cd(II) breaks the ligand to form an open framework structure with the empirical formula, {[Cd(Ox)(H(2)O)(2)]H(2)O}(n)...
