Introduction: Candida spp. has become increasingly resistant to antifungal drugs, with elevated MIC levels causing a negative medical impact and increasing the number of patients at risk of candidiasis. According to the CDC, about 7% of Candida blood samples show reduced susceptibility to fluconazole. Monitoring the antifungal resistance profile of Candida spp. is vital, as non-Albicans species may limit treatment options. Objective: Evaluate the antifungal effectiveness against clinical Candida spp. isolates of six antifungals: amphotericin B, fluconazole, voriconazole, itraconazole, caspofungin, and 5-fluorocytosine. Methods: 100 samples were collected from various clinical samples at the National Centre of Teaching Laboratories in Baghdad, Iraq, from May to December 2023. The effectiveness of six antifungals (fluconazole (FLC), itraconazole (ITR), voriconazole (VRC), amphotericin B (AMB), caspofungin (CAS), and 5-fluorocytosine (5-FC)) was tested using the MA120 Automated ID and AST System (Render) according to CLSI standards. Results: Out of 100 isolates, nine Candida species were identified: C. albicans (54%), C. glabrata (20%), C. dubliniensis (10%), C. tropicalis (6%), C. krusei (5%), C. parapsilosis (2%), and C. rugosa, C. lusitaniae, and C. kyfer (each 1%). The non-susceptible rates to the six antifungals were: 5-FC (42%), FLC (21% intermediate, 9% resistant), AMB (11%), ITR (8%), VRC (6%), CAS (4% intermediate, 1% resistant). Conclusion: We observed increased resistance rates to 5-FC, FLC, ITR, AMB, and VRC, but not to caspofungin. C. albicans showed a high 5-FC non-WT phenotype (72%) with elevated MIC values, while C. glabrata had a 7% non-WT rate against AMB. C. tropicalis and C. parapsilosis revealed limited susceptibility to azoles
In this article, the detailed information was presented about azo-dyes, including a general description of this class of compounds, which included a historical overview, observations on the chemical structure of these compounds, particularly focusing on the azo group (-N=N-) responsible for their coloring properties. In addition, we provided a schematic of the first synthesized azo-compound. Furthermore, we mentioned the general properties of them and viewed a detailed explanation for the categorization of them either aliphatic or aromatic, subdivisions for each category or which category is the most widespread, and then illustrated the types for this class of organic compounds. The effective operator in these compounds called diazonium-sal

Show MoreNovel azo ligand based on tryptamine, and its metal complexes with antioxidant properties were synthesized through chemical methods and characterized through various techniques, including IR, Mass, UV-Vis spectroscopy, elemental analysis, conductivity, magnetic sensitivity, and thermogravimetric analysis. According to the IR spectra of the complexes, the azo-ligand, [5-(2-(3H- 1-indol-3-yl) ethyl) diazenyl) quinolin-8-ol] coordinates with metal ions through the nitrogen atom in the quinoline ring and the oxygen atom of the hydroxyl group. Thermal analysis techniques were employed to investigate the thermal behavior of the compounds. The results revealed that the metal complexes possess higher thermal stability compared to the free ligand. T

Environmentally friendly copper oxide nanoparticles (CuO NPs) were prepared with a green synthesis route via Anchusa strigosa L. Flowers extract. These nanoparticles were further characterized by FTIR, XRD and SEM techniques. Removing of Gongo red from water was applied successfully by using synthesized CuO NPs which used as an adsorbent material. It was validated that the CuO NPs eliminate Congo red by means of adsorption, and the best efficiency of adsorption was gained at pH (3). The maximum adsorption capacity of CuO NPs for Congo red was observed at (35) mg/g. The equilibrium information for adsorption have been outfitted to the Langmuir, Freundlich, Temkin and Halsey adsorption isot
