2. 1. Proteomics in biomarker research : Insights into the effects of aging and environment on biological systems

   Author : Hanna Amelina; Susana Cristobal; Jean-Charles Sanchez; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; proteomics; biomarker; peroxisomes; 2-dimensional gel electrophoresis 2-DE ; mass spectrometry MS ; aging; marine pollution; Biochemistry; Biokemi; Environmental toxicology; Miljötoxikologi; Cell and molecular biology; Cell- och molekylärbiologi; Biochemistry; biokemi;

   Abstract : Proteomics is the global analysis of proteins that covers a broad range of technologies aimed at determining the identity and quantity of proteins expressed in the cell, their three-dimensional structure and interaction partners. In contrast to genome, proteome reflects more accurately on the dynamic state of the cell, tissue, or an organism. READ MORE

4. 2. Gill EROD Activity in Fish : A Biomarker for Waterborne Ah-receptor Agonists

   Author : Alexandra Abrahamson; Ingvar Brandt; Björn Brunström; Janneche Utne Skaare; Uppsala universitet; []
   Keywords : Biology; biomarker; fish; gill; CYP1A; EROD; environmental monitoring; induction; inhibition; PAH; PCB; produced water; Biologi;

   Abstract : Induction of the cytochrome P450(CYP)1A protein and the connected increase in 7-ethoxyresorufin O-deethylase (EROD) activity are common biomarkers in fish. Enhanced activity of this protein signals exposure to Ah-receptor agonists such as chlorinated dioxins, co-planar polychlorinated biphenyls (PCBs) and certain polycyclic aromatic hydrocarbons (PAHs).

5. 3. Proteomic Analysis of Peroxisomal Proteins

   Author : Jia Mi; Susana Cristobal; Bettina Warscheid; Uppsala universitet; []
   Keywords : Cell and molecular biology; peroxisome; proteomics; biomarker; aging; pollution assessment; Cell- och molekylärbiologi;

   Abstract : Peroxisome is a ubiquitous eukaryotic organelle with a single-layer membrane. It maintains various functions that differ depending on the species and cell types, as well as the environmental or developmental conditions. READ MORE

6. 4. Studies of fish responses to the antifoulant medetomidine

   Author : Anna Lennquist; Göteborgs universitet; []
   Keywords : antifouling; fish; medetomidine; ecotoxicology; biomarker;

   Abstract : ABSTRACT Growth of marine organisms, fouling, on man-made constructions submerged in the water is regarded as a major problem. For vessels, fouling increases drag and thereby fuel consumption, wherefore antifouling paints are used. Traditionally, they contain toxic compounds, and several of these have unwanted effects in the environment. READ MORE

7. 5. Development of GC-HRMS procedures for determination of naturally occuring polar compounds in various environmental applications

   Author : Bodil Widell; Dag Broman; Caroline Leck; Joan Grimalt; Stockholms universitet; []
   Keywords : GC-HRMS; steroid hormones; amino acids; perch; size-resolved aerosol; Arctic; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : The overall objectives of this dissertation were to gain further understanding of the two following environmentally significant issues: (i) Determination of natural steroid hormones in blood plasma from perch (Perca fluviatilis) during a reproductive cycle and to evaluate the possibility of using the steroid composition as a biomarker for early signs of endocrine disruptive effects. (ii) Determination of dissolved free amino acids in size resolved airborne particles collected over the Arctic pack ice area (>80°N) in summer and to study their overall relationship with the ocean surface microlayer as a potential source.
