Development and application of test methods for the detection of dietary constituents which protect against heterocyclic aromatic amines

2003

This article describes the development and use of assay models in vitro (genotoxicity assay with genetically engineered cells and human hepatoma (HepG2) cells) and in vivo (genotoxicity and short-term carcinogenicity assays with rodents) for the identification of dietary constituents which protect against the genotoxic and carcinogenic effects of heterocyclic aromatic amines (HAs). The use of genetically engineered cells expressing enzymes responsible for the bioactivation of HAs enables the detection of dietary factors that inhibit the metabolic activation of HAs. Human derived hepatoma (HepG2) cells are sensitive towards HAs and express several enzymes [glutathione S-transferase (GST), N-…

Woodland key habitats in northern Europe: concepts, inventory and protection

2010

Abstract The woodland key habitat (WKH) concept has become an essential instrument in biodiversity-orientated forest management in northern Europe. The philosophy behind the concept is basically the same in all of the countries: to conserve the biodiversity of production landscapes by preserving small habitat patches that are supposed to be particularly valuable. This article reviews the definitions, inventories and implementation processes of WKHs in Sweden, Finland, Norway, Latvia, Estonia and Lithuania. Sweden and the Baltic countries have similar WKH models, while the models in Finland and Norway are clearly deviating. Depending on the country, the definitions emphasize different factor…

Stabilizing Lead Cathodes with Diammonium Salt Additives in the Deoxygenation of Aromatic Amides

2014

Lead is efficiently protected against cathodic corrosion by the addition of diammonium salts in the electrolyte. The cationic coating of the cathode allows the efficient electroreduction of benzamides to benzylamines. The electrochemical deoxygenation of the amide is achieved without the use of oxophilic agents or sacrificial anodes. The surface of the lead cathode stays smooth and the cathode can be reused for multiple runs, providing <2.5 ppm of the crude product. Cyclic voltammetry studies reveal a shift in the onset potential of the hydrogen evolution reaction by −157 mV.

Hot electron injection into aqueous electrolyte solution from thin insulating film-coated electrodes

1998

Hot electron injection into aqueous electrolyte solution was studied with electrochemiluminescence and electron paramagnetic resonance (EPR) methods. Both methods provide further indirect support for the previously proposed hot electron emission mechanisms from thin insulating film-coated electrodes to aqueous electrolyte solution. The results do not rule out the possibility of hydrated electron being as a cathodic intermediate in the reduction reactions at cathodically pulse-polarized thin insulating film-coated electrodes. However, no direct evidence for electrochemical generation of hydrated electrons could be obtained with EPR, only spin-trapping experiments could give information about…

The Legal Instruments Of Protection Of The Environment In A Spa Commune On Poland

2019

Abstract: The author has undertaken to classify the legal instruments of environmental protection of in a health resort municipality (a spa commune) in Poland, regarding the aspect of their impacting the state of protection of natural environment. A spa commune has at its disposal a catalogue of its own tasks, which is complemented by those connected with maintaining medicinal functions of the spa and with meeting the requirements of the environment. The analysis of the content of regulations of law on environmental protection allows concluding that in relation to spas there are no – in principle – separate legal norms which regulate questions connected with protection of environment. While…

Child protection in Europe: development of an international cross-comparison model to inform national policies and practices

2015

We report a five-nations project in comparative child protection to provide recommendations on policy and practice to inform the redevelopment of the Swiss child protection system. The Swiss Federal Government and the Optimus and Oak Foundations commissioned the project—collective title: Association Programme National pour la Protection de l'Enfant. We identify the historical developmental trajectories of child protection systems together with common drivers: the evidential basis for the prevalence and effects of child abuse, the co-joining of social and economic policies and practices to promote early investment in children, the influence of children's rights and comparative international …

Mothers' abusive childhood predicts child abuse

1999

To examine the intergenerational transmission of abuse, the study compared 25 mothers whose child had been under the supervision of the child protection services (CPS) with 25 mothers who had had no contact with the CPS. The groups were compared with respect to their own self-reported childhood abuse, their abuse of their own child and punitiveness. The data were gathered using interviews and files. There were no significant differences between the groups in self-reported childhood physical abuse, but the CPS mothers had experienced more childhood psychological abuse, especially rejection, accusations, terrorizing and corrupting. The groups did not differ in the self-reported physical or ps…

Improving child maltreatment detection systems: a large-scale case study involving health, social services, and school professionals.

2003

Abstract Objectives: The purpose of this 5-year study was to improve detection in two consecutive phases: (a) To close the gap between the number of identified cases and the actual number of cases of child abuse by increasing detection; and (b) To increase the possibility of a broader spectrum of detection. Method: The Balearic Islands (one of the Autonomous Communities of Spain, with 161,287 children under 18 years old) was selected as the study area. Phase 1: front-line professionals (181) from all the health and social services agencies were trained in detection. Phase 2, school professionals (251) from all schools in the territory were also trained. The independent factor was the interv…

Child Abuse Potential

1999

Twenty-five mothers whose children had been under the supervision of the Child Protection Services (CPS group) primarily for neglect and 25 comparison mothers were compared with respect to their child abuse potential as assessed by Milner's Child Abuse Potential Inventory (CAPI). We examined whether the CPS mothers' child abuse potential would still be elevated 7 years after the reported maltreatment of their child. Second, an attempt was made to predict the CAPI scores with the mothers' childhood abuse experiences, adulthood social problems, and socioeconomic status. The CPS mothers scored significantly higher than the comparison mothers on most of the CAPI scales, indicating their persis…
