An aqueous chemical reaction has been used to prepare antifungal ZnS: Mn nanostructures, from manganese chloride, zinc acetate and thioacetamide in aqueous solution. The nanoparticle size has been controlled using thioglycolic acid as a capping factor. The major feature of the ZnS:Mn nanoparticles of average diameter ~ 2.73 nm is that possible preparing the sample from sources non-toxic precursors. The manufactured ZnS:Mn nanoparticles were identified and characterized to investigate the structure, morphology, composition of components of the nanoparticles and optical properties using (XRD, SEM, EDS and UV-Vis spectroscopy) techniques respectively. The agar dilution mechanism used to evaluate of the antifungal activity using ZnS:Mn nanoparticles which showed an efficient antifungal activity against four fungal models Aspergillus fumigatus ,Aspergillus falvus, Trichophyton mentagrophyte, and Microsporum audonii the inhibition increase with the increase of nanoparticle concentration. The antifungal property of manganese doped zinc sulphide nanoparticles creates from the interaction between nanoparticles and water led to generation the interactive oxygen species. Perturbation of the cell membranes due to the existence of Zn ions and S affecting on inhibition rate . the study aimed to evaluation the Antifungal Activity of ZnS:Mn Nanoparticles Against Some Isolated Pathogenic Fungi.

The aim of this study is to show the concepts of nuclear shape and the geometrical picture to the even-even nuclei of 164,166,168E isotopes in the context of the Interacting boson Model IBM-1. The energy spectra were calculated and the effective charge values (eB) of the electromagnetic transition strength were obtained and used to calculate the B(E2) values of the electromagnetic transitions and the quadrupole moment Q of 2+ -states. The Hamiltonian parameters were calculated by taking in account the properties of these nuclei. Comparison were made with the available experimental data and included in tables. The geometrical picture of these nuclei were looked at by calculating the deformation which were represented by the potentia

Show MoreTwo orders of zooblankton,were studied Cladocera and Copepeda in two classes Calanoida and Cyclopoda, where it was studied inside floating cages and for breeding fish placed in the Tigris River in the Rashidiya area. Has been study The population density of zooplankton groups and measure some chemical and physical characters, was studie where she collected samples of zooplankton and water from two locations of cages (inside the cages, after 100m from cages). The study was conducted within six months from January to the end of June 2014 during which there was study of the Wallace pH, water temperature, biological oxygen demand and dissolved oxygen, as to the zooplankton study the species disappeared inside cages of fish and existed after

Show MoreAbstract: The study aimed to investigate the effect of oral administration of hot aqueous extract of beetle cocoon Larinus maculatus Faldermann, in a two doses 50 and100mg/Kg/B.wt for 3 and 6 weeks respectively on the levels of serum glucose, weight of body, and lipid profile in male mice Mus musculus. The results revealed that there was a significant (p<0.05) decrease in serum glucose level was dose and period dependent. Weight of body also reduced significantly (p<0.05) with doses and period dependent. The lipid profile level significantly (p<0.05) decreased in dose and period’s manner in each of Total cholesterol (TC), Triglyceride (TG), High Density Lipoprotein- (HDL), Low Density Lipoprotein (LDL), and Very Low Density Lipoprotei

Structure properties including x-ray diffraction (XRD) and scanning electron microscope (SEM0, also some of mechanical properties and the effect of thermal annealing in different temperature have been studied. The results show that the particle size of a prepared nano-powder was 50 up to 75 nm from SEM, and the crystal structure of the powders (original and nano powder) was rutile with tetragonal cell. An improvement in

Show MoreThis study was conducted to evaluate the activity of pomegranate (Punica granatum L.) peel powder and Pseudomonas fluorescens against Pythium aphanidermatum the causal agent of cucumber seedlings damping-off. Results showed that augmenting of pomegranate peel powder at 2%, P. fluorescens suspension contain 4×107cfu/ml, and the fungicide Previcure N at 0.5 ml/L to culture media (PDA) were inhibited the pathogen growth by 100, 100 and 72.1% respectively. Results of greenhouse experiment indicated that treatment of cucumber seeds with pomegranate peel powder, reduced pre-emergence damping-off percentage to 3.3% compared with 16.6% disease with P. fluorescens and 96.6% in control treatment (pathogen only). No significant differences were ob

... Show MoreA number of disorders characterized by aberrant cell proliferation are referred to as cancers. Cancer is a complicated group of mutagenic diseases that can move or infiltrate to other parts of the body. It develops through a multi-step process. The need for new therapeutic strategies is driven by malignancies resistance to conventional therapies. Use of the Newcastle disease virus as an oncolytic agent has advanced and expanded in immunocompetent carcinoma tumor models by utilizing reverse genetics techniques. Preclinical investigations have shown that recombinant NDV (rNDV-GFP), which expresses foreign genes, is proven to be effective in cancer treatment. Green fluorescent protein gene is usually used as an expression reporter for certa
