2. 1. Quantum Chemical Modeling of Enzymatic Methyl Transfer Reactions

   Author : Polina Georgieva; Fahmi Himo; Nino Russo; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; reaction mechanism; Theoretical chemistry; Teoretisk kemi;

   Abstract : In this thesis, quantum chemistry, in particular the B3LYP density functional method, is used to investigate a number of methyl transfer enzymes. Quantum chemical methodology is today a very important tool in the elucidation of properties and reaction mechanisms of enzyme active sites. READ MORE

4. 2. The Idea of the Walking Dead in Medieval Historical Texts with Particular Reference to the English Examples

   Author : Polina Ignatova; Paul Antony Hayward; Fiona Edmonds; Sophie Page; UK Lancaster University; []
   Keywords : HUMANIORA; HUMANITIES; medieval history; textuality; Latin; death;

7. 5. Impact of epidemiologically identified mixtures of endocrine disrupting chemicals on metabolic programming

   Author : Polina Lizunkova; Joëlle Rüegg; Elin Engdahl; Joachim Sturve; Carl-Gustaf Bornehag; Juliette Legler; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Endocrine disrupting chemicals; Mixtures; Metabolism; Developmental Toxicology; Epigenetics; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

   Abstract : We are ubiquitously exposed to a plethora of endocrine-disrupting chemicals (EDCs), i.e. substances that alter the function(s) of the endocrine system. While ample evidence show individual EDC's influence on developmental processes resulting in adverse health outcomes, less is known about the effects of human-relevant EDC mixtures exposure. READ MORE
