CdO nanoparticles show a strong peak of Plasmon absorption in ultraviolet-visible zone. A strong interaction exists between the surface of CdO nanoparticles and aryl mercaptan compounds. Aryl mercaptan compounds cause to aggregation of CdO nanoparticles linked to DNA/RNA and hence, lead to widening of peak Plasmon of CdO nanoparticles surface at 550 (nm) and emerging a new peak at higher wavelength. In the current project, this optical characteristic of CdO nanoparticles is used to time investigate of interaction between different aryl mercaptanes and CdO nanoparticles. The results were shown that aryl mercaptan compounds with shorter chain length interact faster with CdO nanoparticles. Therefore, a simple and fast method for identification of aryl mercaptanes with various chain length using red shift in surficial Plasmon absorption is presented.

Phytophthora infestans (Mont.) cause potato late blight disease and can infect of roots, tubers, and shoots of the plant. The majority of significant factors in determining the spread of the potato late blight is the cultivation of infected potato tubers and their presence as agricultural plant debris in the agricultural field. Mycelium, zoospores, Oospores, and sporangia, all these structures can make infection, also Oospores with their thick wall can survive for 3 to 4 years under low temperatures. P. infestans responsible to yield losses may arrive at 100% in optimum condition. There are two types of mating patterns for A1 and A2, and this depends on the spread of each type in different environments. This fungus also contains several genetic patterns that have been identified through molecular analysis. The different genotypes in this fungus led to new challenges to make an unstable guideline for the study of virulence and aggressiveness. Different strategies or methods were used to prevent or control late blight disease, included of chemicals, crop rotation, bio-agents, and resistant plants. There are many advantages or disadvantages to each strategy, but several studies mention that using resistant plants and fungicide together on conditions in suitable times and strategies led to perfect effect. This paper investigated in important factors in the spread of late blight disease, and some challenges in this fungus.

Opportunistic fungal infections due to the immune- compromised status of renal transplant patients are related to high rates of morbidity and mortality regardless of their minor incidence. Delayed in identification of invasive fungal infections (IFIs), will lead to delayed treatment and results in high mortality in those populations. The study aimed to assess the frequency of invasive fungal infection in kidney transplant recipients by conventional and molecular methods. This study included 100 kidney transplant recipients (KTR) (75 males, and 25 females), collected from the Centre of Kidney Diseases and Transplantation in the Medical City of Baghdad. Blood samples were collected during the period from June 2018 to April 2019. Twenty one out of 100 renal-transplanted patients were infected with pathogenic fungi, four of the patients were females and 17 were males. There is an observation of a high incidence of fungemia in patients with the abnormal value of blood urea according to PCR and culture results. Referring to fungal isolates the most prevalent was Saccharomyces cerevisiae, which account for 19 isolates out of 21 the other two isolates were Zygosaccharomyces rouxii and Aspergillus flavus. The results of the current study show significant correlation between PCR and culture methods at (P<0.0009).

Antibiotic resistance occurs when microorganisms develop mechanisms that protect them from the effects of antibiotics. Resistant microorganisms are more difficult to treat, require higher doses or alternative therapies may be more toxic, as well as more expensive. Microorganisms that are able to resist many antibiotics are called multi-resistant. All kinds of microorganisms can develop this ability to resist; Fungi develop resistance against antifungals, viruses develop resistance against antivirals, protozoa develop resistance against protozoa, and bacteria develop resistance against antibiotics. Resistance arose naturally either through genetic mutations or through the transmission of resistance from one sex that has acquired it to another that has not yet acquired it, in particular. Accordingly, it is urgent to reduce the misuse of antibiotics by not using them only when they are really needed.

Isatin is a heterocyclic nitrogen compound that has attracted much interest in recent years due to its diverse biological and pharmacological activities. It can be used in many medical and biological applications, such as antidiabetic, antibiotic, and anticancer agents. The isatin molecule can also be prepared from different substrates by various methods, such as the methods of Sandmeyer, Stolle, Gassman, Meanwell and Hewawasam and others. On the other hand, the isatin molecule can undergo various chemical reactions, such as oxidation, Friedel-Crafts reaction, ring expansion, aldol condensation, and alkylation reactions. As a result of these reactions, several biologically useful biomolecules are formed, including 2-oxindoles, tryptanthrin, indirubins and others. Therefore, the aim of this review was to provide an overview of the synthetic methods of the isatin molecule and its derivatives and to examine the various chemical reactions it undergoes. In addition, a list of some of the recently documented biological activities of isatin derivatives was compiled, such as antidiabetic, antibacterial, anticancer, and other properties.

Soil is one of the favorable habitat for microorganism. It considered being the home of wide range of them in particularly, bacteria and fungi. Southern Iraq is characterized by a multiplicity of ecosystem, which include desert, agricultural and marine areas, each of which has special composition that differs from the neighboring system, whether in terms of vegetation or various environmental factors. This in diversity, in turn, may lead to microbial diversity that can be used in different biotechnologies. Regarding that little is known about yeast diversity in such habitats, and therefore the current study aims to assess the yeast community in soil and sediments samples from Basrah and Dhi-Qar provinces, Southern Iraq. Thirty-one species belong to 19 genera were encountered. The isolated species consist of 16 species of Ascomycota and 15 species of Basidiomycota. The soil of Basrah and Dhi-Qar support the growth of diverse species belonged to the genera Aureobasidium, Cutaneotrichosporon, Debaryomyces, Filobasidium Geotrichum, Hanseniaspora, Lodderomyces, Meyerozyma, Symmetrospora, Torulaspora, Vishniacozyma, Pichia, Yarrowia, Cystobasidium, Galactomyces, Rhodotorula, Wickerhamomyces, Candida and Naganishia. One hundred and twelve fungal isolates were identified using the conventional methods depending on morphological characteristics. CHROMagar candida was used as differential culture medium. Iodine stain was used to differentiate ascospores and basidiospores. In addition biochemical method represented by VITEK was used as well as molecular identification. This study represents the first report of occurrence of yeast species in soil and surface sediment samples from Basrah and Dhi-Qar provinces, Southern, Iraq, with effect of some ecological factors on isolation yeast from different location.

Six derivatives of novel triazoles were produced from some substituted benzoic acid with thiocarbazide via method of grinding. The produced Chemicals were described via 1HNMR, IR, and 13CNMR spectra examinations. Produced derivatives of C2H3N3 were examined and assessed as reducing of corrosion in 0.5 M HCl for low-C steel utilizing procedure of losing weight. It was noticed that such chemicals had an encouraging act as reducer counter to mild steel corrosion of in solution being acidic. Reducing of maximum action was assessed at various concentrations and temperature of effector. Competence of corrosion reducer surpassed 96%. The exceptional action was due to inhibitor films adsorption development on surfacing steel. Reducing adsorption on surface of steel tracked Langmuir adsorption isotherm (LAI). The results were long-established BY theoretical calculations of quantum chemistry.

A new metal-free macrocyclic Schiff base ligand bearing two metal cavities incorporated with two sets of N3O2 donor atoms derived from 2, 6-diaminopyridine and isatine was synthesized. The new ligand was used to prepare homo and hetero binuclear macrocyclic Schiff base complexes with Ni (II), Cu (II), ZrO (II) and Ba (II) metal ions. The ligand and metal complexes were characterized using Fourier transform infrared (FT-IR), UV–vis, mass spectroscopy, elemental analysis (CHN), thermo gravimetric analysis (TGA), magnetic susceptibility, and molar conductivity measurements. The DFT calculations using the B3LYP functional method have been applied to obtain the geometry and electronic properties of the ligand and its metal complexes to support the experimental data. To describe the reactivity of the title molecules, the HOMO and LUMO levels and Mulliken atomic charges were determined.
