Evaluation of Invasive Intra-abdominal Candidiasis in Crohn Disease at the Time of Surgery
Martin Šašala,Emeše Majorová,Andrej Vrzgula,Iveta Fandáková 대한대장항문학회 2020 Annals of Coloproctolgy Vol.36 No.1
Purpose: The aim of this study was to determine whether a connection exists between Crohn disease and fungi, specifically Candida albicans, because one possible cause of disease is thought to be the presence of fungi in the intra-abdominal cavity. The diagnosis of invasive candidiasis is difficult due to the lack of specific clinical manifestations of the disease. A retrospective evaluation of the presence of invasive candidiasis was done in a group of 54 patients with Crohn disease and in a group of 31 patients who received surgery primarily for right-sided cancer of the colon. Methods: Culture samples were obtained from the wall of the extraluminal portion of the terminal ileum and the adjacent mesenterium, and then sent to the microbiology laboratory for further investigation. Sabouraud agar (SGC2) and chromID Candida agar (CAN2) were used for both short-term (48 hours) and long-term (10 days) cultivation. Results: Pearson chi-square test revealed a statistically significant difference in the prevalence of fungi and yeast between the 2 groups of patients (χ2 = 4.3873, P < 0.05). Conclusion: Patients with Crohn disease had a significantly higher prevalence of fungi and yeasts in the intra-abdominal cavity compared with cancer patients.

Plasma-Assisted Green Synthesis of ZnO Directly on Polyethylene Terephthalate Fabric
Anja Verbič,Katja Brenčič,Gregor Primc,Miran Mozetič,Martin Šala,Marija Gorjanc 한국섬유공학회 2023 Fibers and polymers Vol.24 No.1
This article presents green in situ synthesis of ZnO directly on polyethylene terephthalate (PET) fabrics using pomegranatepeel extract. The surface of PET was activated by environmentally friendly oxygen plasma, and the process was comparedto alkali treatment where the extract of wood ash was used instead of classical chemicals. Sorption analysis showed that thehydrophilic character of the plasma-treated sample was much better than that of the alkali-treated and untreated samples. Both treatments slightly decreased the breaking strength and elongation of the fabric. Scanning electron microscopy, colourmeasurements, dispersive X-ray spectroscopy, and antioxidant activity investigations showed that the ZnO particles were successfullysynthesised on alkali- and plasma-treated PET. The liquid chromatography-mass spectrometry results showed thatellagic acid and punicalagin were the most abundant compounds in the pomegranate peel extract that enabled the synthesisof ZnO. The UV protection, amount of ZnO, and uniformity were the highest for the ZnO prepared on the PET samples bythe plasma-assisted green synthesis. Additional optical assessment of fabric porosity and thickness measurements confirmedthat these fabrics have excellent UV protection due to the presence of ZnO.
