Modulation of carcinogen metabolizing cytochromes p450 in rat liver and kidney by cabbage and sauerkraut juices: comparison with the effects of indole-3-carbinol and phenethyl isothiocyanate
PublicationThis study investigated the effect of raw cabbage and sauerkraut juices on the activity and expression of CYP1A1, 1A2, 1B1 and 2B in Wistar rat liver and kidney. The results were compared with those of two commercially available products of glucosinolates degradation: indole-3-carbinol (I3C) and phenethyl isothiocyanate (PEITC). Significant differences in the effect of the cabbage juices as well as I3C and PEITC between the liver...

Mutagenic and Carcinogenic Compounds in Food
PublicationFood is a major environmental human cancer risk factor. One of the reasons for this is that food products contain substances that exhibit mutagenic and carcinogenic potential which may induce the transformation of normal somatic cells into cancerous cells. These compounds occur in food as a result of microbial contaminations (mycotoxins produced by molds), are generated from natural food components upon processing (e.g. heterocyclic...

Chapter 19. Mutagenic, Carcinogenic, and Chemopreventive Compounds in Foods
PublicationMutagenami są nazywane czynniki i substancje mogące powodować zmiany w zapisie genetycznym, kancerogenami lub czynnikami rakotwórczymi natomiast te, które przyczyniają się do powstawania nowotworów, z wyłączeniem podatności uwarunkowanej genetycznie. Przetwórstwo, a w szczególności obróbka termiczna żywności, jest główną przyczyną tworzenia się mutagenów i kancerogenów, niemniej jednak zwiekszają one trwałość żywności. Badania...

Phospholipids as potential prevention factor in carcinogenesis
PublicationPhospholipids are a group of complex lipids, which can be used in cancer chemoprevention. Glicerophospholipids are composed of fatty acids esterified to a glycerol backbone, a phosphate group and a hydrophilic residue such as: cho- line, ethanoloamine, serine or inositol. In the sn-2 position of glicerophospholipid usually there are unsaturated fatty acids, i.e. linolenic acid, while in the sn-1 position more typi- cal are saturated...

Cellular senescence induced by DNA damage and its role in carcinogenesis and chemotherapy
PublicationUszkodzenia DNA indukują w komórce różne procesy, w tym starzenie komórkowe, co może uruchamiać proces karcinogenezy jak i być związane z odpowiedzią na leki przecinowotworowe. Biologiczna rola starzenia komórkowego nie jest jednak jasna. Zasugerowano, że proces starzenia komórkowego może hamować proces karcinogenezy poprzez indukcję nieodwracalnego zahamowania wzrostu przez czynniki genotoksyczne. Indukcja starzenia komórkowego...

The properties, functions and use of selenium compounds in living organisms
PublicationSelenium occurs in the environment in inorganic and organic compounds. For many years it was regarded as a toxic element, causing numerous illnesses and diseases. But research in the last 50 years has revealed a "bright side" to this element, especially as a component of selenoproteins, selenium makes a significant contribution to the health of humans and animals. The selenium content in an organism depends on its concentration...

Review of cigars and cigar-type products as potential sources of consumer exposure to heavy metals
PublicationThe popularity of cigars, growing since 1993, has not gone hand in hand with the increased interest of researchers in these products. Although the literature widely describes the harmfulness of tobacco and the content of toxic substances in tobacco products, the topic is often treated selectively as relating primarily to cigarettes and rarely extends to other products of the broadly defined tobacco industry. However, there is no...

A procedure for the determination of dichloromethane and tetrachloroethene in water using pervaporation and gas chromatography
PublicationIn the present study, pervaporation was applied to the determination of tetrachloroethene (PCE) and dichloromethane (DCM) in liquid samples. PCE is the most commonly used solvent in dry-cleaning processes. PCE belongs to group 2A of carcinogens (probably carcinogenic to humans) according to the classification of the International Agency for Research on Cancer (IARC). DCM is also widely used as an industrial solvent for the purification...

Removal of Arsenic from Wastewater Using Hydrochar Prepared from Red Macroalgae: Investigating Its Adsorption Efficiency and Mechanism
PublicationArsenic (As) is a prominent carcinogen component produced via both geogenic and anthropogenic processes, posing serious risks to human health. This study aimed to investigate the potential of hydrochar prepared from red macroalgae for removing As from synthetic wastewater. The hydrochar was produced through 5 h hydrothermal carbonization (HTC) treatment at 200 °C, and then, chemically activated with ferric chloride hexahydrate...

Study of the anticancer potential of Cd complexes of selenazoyl-hydrazones and their sulfur isosters
PublicationThe biological activity of Cd compounds has been investigated scarce since Cd has been recognized as a human carcinogen. However, the toxicity of cadmium is comparable to the toxicity of noble metals such as Pt and Pd. The paradigm of metal toxicity has been challenged suggesting that metal toxicity is not a constant property, yet it depends on many factors like the presence of appropriate ligands. Studies on anticancer activity...
