Wstępna ocena narażenia psów i kotów na dioksyny i związki pokrewne zawarte w karmie dla zwierząt domowych
No full textCelem projektu realizowanego w ramach konkursu Miniatura 8 (nr projektu: 2024/08/X/NZ7/00997), było określenie narażenia zwierząt towarzyszących człowiekowi (psy i koty) na Trwałe Zanieczyszczenia Organiczne (TZO) takie jak 7 kongenerów polichlorowanych dibenzo-p-dioksyn (PCDD), 10 kongenerów polichlorowanych dibenzofuranów (PCDF) oraz 18 kongenerów polichlorowanych bifenyli (PCB), które mogą znajdować się w karmie dla zwierząt domowych.Materiał badawczy stanowiły zakupione próbki różnych rodzajów karm komercyjnych dla psów oraz kotów. Dla każdego rodzaju zwierzęcia przebadanych zostało 20 próbek dedykowanej karmy, połowę z nich stanowiły karmy suche a drugą połowę karmy mokre. Łącznie przebadano 40 próbek. W badaniach zastosowano metodę kapilarnej chromatografii gazowej sprzężonej z wysokorozdzielczą spektrometrią mas. Analizę próbek wykonano z zastosowaniem akredytowanej procedury opartej na technice chromatografii gazowej sprzężonej ze spektrometrią mas wysokiej rozdzielczości HRGC-HRMS. Metoda ta uważana jest za złoty standard w analityce dioksyn, ponieważ jako jedyna pozwala na tzw. analizę tła, dostarcza pełnych informacji o występujących kongenerach oraz o poziomie ich stężeń. Cechuje ją wysoka czułość [wykrywanie PCDD, PCDF oraz PCB na poziomie pikogramów TEQ (10-12g)].W żadnej z przeanalizowanych karm nie stwierdzono stężenia dioksyn i PCB przekraczającego najwyższy dopuszczalny poziom (ML) lub próg podejmowania działań (ang. action level- AL), zgodnie z rozporządzeniem 277/2012/UE. Poziomy analizowanych kontaminantów w badanych próbkach były niskie. Świadczy to o dobrej jakości karm dla psów i kotów w odniesieniu do dioksyn i PCB.</p
The proteome profile of hemolymph in the false widow spider Steatoda grossa (Theridiidae) under cadmium and copper intoxication
No full textThe dataset provides research data on the effects of long-term exposure to xenobiotic cadmium and biogenic copper, administered through contaminated prey, on the protein profile of the hemolymph in Steatoda grossa (Araneae: Theridiidae) spiders. The study focuses on both quantitative and qualitative changes in the hemolymph proteome in response to artificial and natural immunostimulants: phorbol 12-myristate 13-acetate (PMA) and bacterial suspensions (Staphylococcus aureus [G+], Pseudomonas fluorescens [G-]).The collected data include:• Analysis of the protein profile in female Steatoda grossa spiders that were chronically exposed to cadmium and copper through their food and were additionally immunostimulated.• Results of heavy metal concentrations in the bodies of spiders.The protein analysis was performed using 2D DIGE. Proteins were quantified with the 2D Quant Kit and cleaned with the 2D Clean-Up Kit. They were labeled with fluorescence dyes, followed by rehydration on an IPG strip and isoelectric focusing (IEF). After focusing, proteins were reduced and alkylated. The second dimension was run using polyacrylamide gels. Protein maps were visualized with a Typhoon FLA 9500 scanner and analyzed using Image Master™ 2D Platinum 7.0 software. Spots of interest were excised after silver nitrate staining for further analysis.Peptide separation was performed using a Dionex UltiMate 3000 RSLC nano system and Bruker AmaZon Speed ETD mass spectrometer. Peptides were loaded onto a C18 precolumn, separated on a C18 analytical column, and analyzed by MS and MS/MS. Data were processed using Compass Data Analysis and ProteinScape 3. Protein identification was done via the MASCOT Server with databases restricted to Metazoa or Araneae. Proteins with a score >37 were considered identified.</p

No full textData obtained during the research experiments (leaching with citric acid, bioleaching with the use of A. thiooxidans bacteria and A. niger funghi) of the project entitled "Biological recovery of metals from used lithium-ion batteries with the use of extremophilic microorganisms" financed by the grant Miniatura 6 of the National Science Center (NCN) 2022/06/X/ST10/00230.The research aimed to determine the potential of biological methods using extremophilic microorganisms to recover metals from waste lithium-ion batteries - cobalt, copper, lithium and nickel. The dataset contains the results of research conducted in this area. As part of the experiments, the metal recovery rates from the battery powder were determined by the metal concentrations in the starting material and solutions after leaching using the ICP-OES method. In addition, the quantitative and qualitative composition of the battery powder and residues after leaching using the XRD method was established. The README file contains a description and explanation of all deposited files.</p
Raw data for publication "Halloysite supplemented in the diet, and sex of Cherry Valley ducks affects growth, carcass composition, meat quality, and jejunum and leg bone strength"
No full textNatural minerals like halloysite may enhance waterfowl nutrition. This study evaluated the effects of 1% halloysite in the diet of male and female Cherry Valley ducks on growth, carcass traits, meat quality, and jejunum and leg bone strength. Ducks were assigned to control and experimental groups (50 birds each), with halloysite added to the experimental group’s diet for 42 days. Halloysite reduced final body weight and weight gain but increased liver weight. Female ducks had more pectoral muscle, total muscle, and abdominal fat, while males had more carcass remains. Treated ducks showed lower protein but higher collagen, fat, and water in pectoral muscles. Control ducks had redder and yellower leg muscles; males had more fat than females. Halloysite increased jejunum strength. Halloysite negatively affected growth but altered meat quality and improved jejunum strength. Its mixed effects suggest further research is needed.The dataset presents raw data related to the publication "Halloysite supplemented in the diet, and sex of Cherry Valley ducks affects growth, carcass composition, meat quality, and jejunum and leg bone strength".The data was obtained as a part of a project entitled "Multiomic research of the gastrointestinal tract and phenotypic features of ducks fed with feed with the addition of aluminosilicates." No. UMO-2021/43/D/NZ9/01756, financed by the National Science Center (Poland). (Project Investigator: Banaszak, Mirosław)This dataset contains data on:- chemical composition of feed;- individual body weight of ducks;- production results for replicates;- tissue composition of carcasses;- meat quality characteristics;- physical characteristics of bones;- physical characteristics of jejunum.</p
