Examination of epigenetic inhibitor zebularine in treatment of skin wounds in healthy and diabetic mice
PublicationDNA methyltransferase inhibitor zebularine was proven to induce regeneration in the ear pinna in mice. We utilized a dorsal skin wound model to further evaluate this epigenetic inhibitor in wound healing. Full-thickness excisional wounds were made on the dorsum of 2 and 10-month-old healthy BALB/c and 3 and 8-month-old diabetic (db/db) mice, followed by topical or intraperitoneal zebularine delivery. Depending on the strain, age,...

Preliminary investigations on biological treatment of aqueous phase separated from cutting fluids
PublicationZaprezentowano wyniki fizykochemicznego podczyszczania przepracowanych cieczy obróbkowych pochodzących z różnych źródeł. Emulsje przepracowanych cieczy obróbkowych zostały rozdzielone na fazę organiczną i wodną z wykorzystaniem różnych koagulantów. Wydzielona faza wodna została następnie poddana biologicznemu oczyszczaniu z wykorzystaniem osadu czynnego. W wyniku oczyszczania ścieków uzyskano 59-88% obniżenie wartości ChZT.

Evaluation with micromagnetic methods of T22 and P92 steels microstructure modified by thermal treatment
PublicationOpisano rezultaty badań wywołanych obróbką cieplną zmian mikrostruktury na właściwości magnetosprężyste stali T22 oraz P92. Badano pętle histerezy amagnetycznej, polowy efekt Barkhausena (HBE) oraz emisję magnetoakustyczną (EMA). Wykazano, iż komplementarna analiza HBE oraz EMA (obwiednie natężenia i szybkości zliczania impulsów) pozwala na jakościową ocenę charakteru zmian mikrostruktury badanych materiałów.

Comparison of two model concepts for simulation of nitrogen removal at a full-scale biological nutrient removal pilot plant
PublicationCelem badań było porównanie zdolności predykcyjnych dwóch mechanistycznych modeli procesu osadu czynnego (ASM1 i ASM3). W tym celu wykorzystano bazę danych empirycznych z pilotowej oczyszczalni ścieków Gummerwald w Hanowerze (Niemcy). Oba badane modele prognozowały szczytowe stężenia azotu amonowego na poziomie >8 gN/m3 w ciągu, którego obciążenie hydrauliczne wzrastało czterokrotnie w porównaniu do okresu bezdeszczowego. Prognozowany...

Chemical and biological evaluation of antioxidant activity of endogenous redox-active compounds compared to plant-derived exogenous antioxidants
PublicationThe research conducted so far has shown that endogenous antioxidants, despite being regarded as the first line of antioxidant defense, may not be sufficient to maintain redox homeostasis in cells exposed to oxidative stress. The results obtained in the doctoral dissertation show that endogenous redox-active compounds were moderate or weak scavengers of ABTS and DPPH radicals, while in cellular setting, their impact on the reducing...

Detection of the Plant Pathogen Pseudomonas Syringae pv. Lachrymans on Antibody-Modified Gold Electrodes by Electrochemical Impedance Spectroscopy
PublicationThe present work describes an impedimetric immunosensor for Pseudomonas syringae pv. lachrymans (Psl) detection. This pathogen infects many crop species causing considerable yield losses, thus fast and cheap detection method is in high demand. In the assay, the gold disc electrode was modified with 4-aminothiophenol (4-ATP), glutaraldehyde (GA), and anti-Psl antibodies, and free-sites were blocked with bovine serum albumin (BSA)....

Manufacturing and Recycling Impact on Environmental Life Cycle Assessment of Innovative Wind Power Plant Part 1/2
PublicationWind power plants are considered as ecologically-clean source of energy. However, manufacturing processes cannot be treated that way. Manufacturing processes consume huge amount of electrical and thermal energy and significant amount of materials, e.g. steel, polymers, oils and lubricants. All of the above could be potentially harmful for environment. There are not many works and publications regarding life-cycle analysis of wind...

Transformation of polyvinyl chloride (PVC) into a versatile and efficient adsorbent of Cu(II) cations and Cr(VI) anions through hydrothermal treatment and sulfonation
PublicationThe reuse of waste polyvinyl chloride (PVC) has drawn much attention as it can reduce plastic waste and associated pollution, and provide valuable raw materials and products. In this study, sulfonated PVC-derived hydrochar (HS-PVC) was synthesized by two-stage hydrothermal treatment (HT) and sulfonation, and shown to be a versatile adsorbent. The reoval of Cu(II) cations and Cr(VI) anions using HS-PVC reached 81.2 ± 1.6% and 60.3...
