  1. 21. Quantum Chemical Studies of Aromatic Substitution Reactions

    Författare :Magnus Liljenberg; Tore Brinck; Leif Eriksson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teoretisk kemi och biologi; Theoretical Chemistry and Biology;

    Sammanfattning : In this thesis, density functional theory (DFT) is used to investigate the mechanisms and reactivities of electrophilic and nucleophilic aromatic substitution reactions (SEAr and SNAr respectively). For SEAr, the σ-complex intermediate is preceded by one (halogenation) or two (nitration) π-complex intermediates. LÄS MER

  3. 22. Modern Computational Physical Chemistry : An Introduction to Biomolecular Radiation Damage and Phototoxicity

    Författare :Jorge Llano; Leif A. Eriksson; Ulf Ryde; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; statistical mechanics; biophysical chemistry; interface; surface thermodynamics; bioelectrochemistry; ionizing radiation; radiation therapy; condensed matter; computational chemistry; nucleic acids; radiation damage; electrode potential; electronic transport; photochemistry; strand break; photodynamic action; cytostatic; solvation; solvated electron; absolute potential; chemical potential; Biologi; Biology; Biologi;

    Sammanfattning : The realm of molecular physical chemistry ranges from the structure of matter and the fundamental atomic and molecular interactions to the macroscopic properties and processes arising from the average microscopic behaviour.Herein, the conventional electrodic problem is recast into the simpler molecular problem of finding the electrochemical, real chemical, and chemical potentials of the species involved in redox half-reactions.

  4. 23. Computational studies of photodynamic drugs, phototoxic reactions and drug design

    Författare :Klefah Abrahem Klefah Musa; Leif Eriksson; Nino Russo; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NSAIDs; fluoroquinolone; photodegradation; phototoxicity; drug design; DFT; TD-DFT; Biophysical chemistry; Biofysikalisk kemi; Chemistry; Kemi;

    Sammanfattning : The most important criterion when designing new drugs or improving old ones in order to prevent side effects or at least diminish them is drug safety. Treatment of all diseases generally needs use of either topical application or systemic medications (transported in the blood) during a certain period of time. LÄS MER

  5. 24. Experimental and Clinical Studies of Oxidative Stress in Pre-Eclampsia

    Författare :Peppi Nash; Ulf Eriksson; Matts Olovsson; Leif Jansson; Lucilla Poston; Uppsala universitet; []
    Nyckelord :Obstetrics and gynaecology; Pre-eclampsia; Oxidative stress; Diabetes; Placenta; Rat; Antioxidants; Suramin; Vitamin E; Vitamin C; PAI-1; PAI-2; Obstetrik och kvinnosjukdomar;

    Sammanfattning : Impaired placentation and oxidative stress are proposed to play major roles in the pathogenesis of pre-eclampsia (PE). It has recently been pointed out that PE might be more than one disease and may have several different pathogeneses. LÄS MER

  7. 25. Interprofessionella teambesök i svensk barnhälsovård - en resurs att utveckla : En studie om teamarbete ur sjuksköterskors, läkares och psykologers perspektiv

    Författare :Ulrika Svea Nygren; Lena Nordgren; Ylva Tindberg; Leif Eriksson; Håkan Sandberg; Marie Golsäter; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Child Healthcare Service; Interprofessional teamwork; Proportional universalism; Barnhälsovård; Teamarbete; Proportionerlig universalism; Team-based visits; Team competence; Mixed method; Caring Sciences; Vårdvetenskap;

    Sammanfattning : Interprofessional teamwork has been described as a key method in promoting health and preventing illness in children. However, evidence-based knowledge about which form of teamwork in Child Healthcare Services (CHS) that enables a holistic view of the child in his or her family, considering medical, psychological and social circumstances, is required.
