1Wyszukiwanie od początku wyrazu: Wyraz preane znajdzie "preanestetyczny", ale anestetyczny nie znajdzie tego słowa (wyszukiwanie patrzy tylko na początek wyrazów)
-Wykluczanie słów (znak minus): Poprzedzenie wyrazu znakiem - znajdzie wszystkie tytuły NIE zawierające danego słowa, np. -onkologia znajdzie prace bez słowa "onkologia"
"Wyszukiwanie całych fraz (cudzysłów): Cudzysłów powoduje szukanie całych ciągów znaków w tej samej kolejności. Np. "Uniwersytet Medyczny" wyszuka tylko prace z dokładnie tą nazwą, podczas gdy wpisanie bez cudzysłowu może znaleźć "Medyczny Uniwersytet"

Abstract Petasites hybridus extracts are valued for their antimigraine and anti-inflammatory properties but require pyrrolizidine alkaloids-free and compositionally consistent extraction methods. Supercritical CO₂ extraction offers an alternative to organic solvents, yet its performance for butterbur has not been systematically optimized or linked to chemical and biological outcomes. This study aimed to optimize extraction conditions using Box–Behnken design and evaluate extraction yield, sesquiterpenoid content, pyrrolizidine alkaloids levels, and cyclooxygenase-2 (COX-2) inhibitory activity across the investigated extraction conditions. Fifteen extracts were prepared across a three-factor Design of Experiments (DOE). Sesquiterpenoids and pyrrolizidine alkaloids were quantified using UPLC-PDA-MS/MS. COX-2 inhibition was assessed using a fluorometric screening assay. Data were modelled using response surface methodology and multivariate regression analysis. Extraction yield responded to temperature and CO₂ consumption, while sesquiterpenoid composition remained stable. Supercritical CO₂ …
Abstract Glioblastoma (GBM) remains the most lethal brain tumor with limited treatment options and poor prognosis. The design of new anti-GBM drug candidates is of utmost need. Here we assessed the activity of 1,2,4-triazolo[3,4-a]phthalazine and 1,2,4-triazolo[4,3-b]pyridazine derivatives in GBM cell lines, patient-derived primary GBM cells as well as normal human astrocytes (NHA). The tested compounds presented considerable cytotoxicity against GBM cells in MTT assay, and two of them were much less harmful to NHA. They also significantly decreased the ability of GBM cells to form colonies. The initial list of possible molecular targets was retrieved from the SuperPred tool and intersected with GBM-related genes extracted from publicly available datasets. The obtained records were subjected to further functional pathway enrichment analysis which identified histone modifying pathways among the most enriched ones. …
Abstract Studies on the influence of radiotherapy on the structure, thermal properties, and thermo-oxidative decomposition of breast silicone implants were conducted. Additionally, the potential use of breast silicone implant waste as a component in layered composites was investigated. ATR-FTIR, DSC, and TG/DTG/FTIR analyses confirmed that radiation does not affect the structure, thermal properties, or oxidative decomposition behavior of the shell and gel layers of breast silicone implants. The conducted tests demonstrated the successful fabrication of composite materials using a PUM matrix and breast silicone implant waste. The presence of the PUM matrix in the manufactured composites influenced the crystallization and melting behavior of the silicone phase. Moreover, the incorporation of a silicone implant waste layer into the composites increased their thermal stability while decreasing the glass transition temperature, storage modulus …
Abstract Cognitive dysfunction and neurodegenerative disorders represent an increasing clinical challenge in aging dogs and cats, while objective and minimally invasive biomarkers for early detection and disease monitoring remain limited. Tear film is a biologically active fluid reflecting both local and systemic processes and offers a practical, non-invasive source of potential biomarkers in geriatric veterinary patients. Proteomic analyses of canine and feline tear film have revealed a complex protein composition, including molecules involved in inflammation, oxidative stress, immune regulation, and cellular homeostasis—processes implicated in neurodegeneration. However, growing evidence from human and veterinary research emphasizes the importance of CNS-specific and mechanistically informative biomarkers, such as markers of axonal injury, synaptic degeneration, and glial activation, which may provide a more precise framework for interpreting peripheral proteomic alterations. This review summarizes current knowledge …
The study aimed to assess the influence of two packaging methods (under vacuum, VP vs. air, AP) on the quality of fish balls from carp (Cyprinus carpio) stored at +4 °C up to 14 days after preparation. The air-packed and vacuum-packed fish balls were analyzed for physicochemical parameters, microbiological status, and sensory characteristics. The packaging method and storage time interaction significantly (p < 0.05) affected the acid value (AV) and peroxide value (PV), as well as the thiobarbituric acid reactive substance index (TBARS), with lower values of these parameters observed in vacuum-packed samples at 7 d (AV, PV, TBARS), 9 d (TBARS), 12 d (PV) and 14 d (TBARS) of storage. Moreover, vacuum packaging helped maintain a beneficial oil absorption and pH, and partially slowed down the occurrence of undesirable …
