Synthesis, Characterization, And Antibacterial Activities Of Manganese (II), Cobalt(II), Iron (II), Nickel (II) , zinc (II) And Cadmium(II) Mixed- Ligand Complexes Containing Amino Acid(L-Valine) And Saccharin

A new six mixed ligand complexes of some transition metal ions Manganese (II), Cobalt(II), Iron (II), Nickel (II) , and non transition metal ion zinc (II) And Cadmium(II) with L-valine (Val H ) as a primary ligand and Saccharin (HSac)  as a secondary ligands  have been prepared. All the prepared complexes have been characterized by molar conductance, magnetic susceptibility infrared, electronic spectral, Elemental microanalysis (C.H.N) and AA . The complexes with the formulas   [M(Val)2(HSac)2] M= Mn (II) , Fe (II) , Co(II) ,Ni(II), Cu (II),Zn(II) and  Cd(II) L- Val H= (C5H11NO2)  , C7H5NO3S   The study shows that these complexes have octahedral geometry; The metal complexes have been screened for their in microbiological activities against bacteria.  Based on the reported results, it may be concluded that the deprotonated ligand  (L-valine) to (valinate ion (Val-)  by using (Na OH) coordinated to metal ions as bidentate ligand through the oxygen atom of the carboxylate group(-COO-), and the nitrogen atom of the amine group (NH2), where the saccharin (H Sac) coordinated as a monodentate through the nitrogen atom.

Synthesis ,characterization and antibacterial activity of mixed ligand complexes of some metals with 1-nitroso-2-naphthol and L-phenylalanine

The mixed ligand complexes of Mn(II),Fe(II),Co(II),Ni(II),Cu(II), Zn(II) and Cd (II) with 1-nitroso-2-naphthol (C10H7NO2), symbolized (NNPhH)] and amino acid L-phenylalanine( C9H10NO2), symbolized (phe H),  were synthesized and characterized by: Melting points, Solubility, Molar conductivity. determination the percentage of the metal in the complexes by flame(AAS), Molecular weight determined by  Rast’s Camphor method, susceptibility measurements, Spectroscopic Method [FT-IR and UV-Vis], And Program  [Chem office– CS .Chem.– 3D pro 2006] was used for draw compounds . The results showed that the deprotonated   two  ligands acts as a bidentate ligand ,  (phe-) was coordinated to the metal ions through the oxygen  of  the  carboxylic  group  and  the nitrogen of the amine and  the 1-nitroso-2-naphthol ligand was coordinated to the metal ions through the oxygen and nitrogen atoms. The electronic absorption spectra and magnetic susceptibility measurements of the complexes indicate octahedral geometry for all the complexes.

Water And Alcohol Extraction Of Thyme Plant (Thymus Vulgaris) And Activity Study Against Bacteria, Tumors And Used As Anti-Oxidant In Margarine Manufacture

Isolation had been done for active substances from Thyme plant (Thymus Vulgaris) such as volatile oils, Saponins and Tannins. The percentage in form was (21.1%),(59.2%),( 9.7%) respectively. Also a study of anti-bacterial activity of extracts from Thyme using two types of pathogenic bacteria Escherichia Coli and aurous Staphylococcus showed the ability of inhibition for all different extracts by vary inhibition diameters for different active substances, concentrations and bacteria. One type of cancer cellular line used to study the effect of Thyme  extracts on the growth of cells in the laboratory and thus know the specifications of extracts as anti-tumor, (L20B) cell line have been used which  is mice Transformed cell Line. The possibility of using alcohol extract as anti-oxidant to be add to ghee or vegetable oil, the sensory evaluation and physical results were very good over full year.

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
