  1. 21. Archaeological Genetics - Approaching Human History through DNA Analysis

    Författare :Evangelia Daskalaki; Anders Götherström; Mattias Jakobsson; Walther Parson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ancient DNA; pyrosequencing; molecular genetics; aDNA; neolithization; evolutionary genetics; mtDNA; viking age; archaeological genetics; genetik; evolutionsgenetik; naturvetenskap; neolitisering; vikingatid; arkeologisk genetik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : There are a variety of archaeological questions, which are difficult to assess by traditional archaeological methods. Similarly, there are genetic and population genetic questions about human evolution and migration that are difficult to assess by studying modern day genetic variation. LÄS MER

  4. 23. Cellular effects of ionizing radiation : Relevant for understanding cancer risk after medical and environmental radiation exposures

    Författare :Pamela Chiaka Akuwudike; Andrzej Wojcik; Lovisa Lundholm; Kerstin Borgmann; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation; DNA damage; radiation-induced carcinogenesis; second primary cancer; cisplatin chemoradiotherapy; dose fractionation; low dose; low dose rate; dose and dose rate effectiveness factor DDREF ; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Radiation-induced cancers are stochastic and delayed effects of exposure to ionizing radiation. The dose-response relationship for radiation-induced cancers at both low dose/low dose rates and high doses (doses encountered during radiotherapy) remains unclear. LÄS MER

  5. 24. Hypothermia and radiation. Effects on DNA, chromatin and cellular survival

    Författare :Kerstin Elmroth; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cells; temperature; irradiation; dsb; survival; fluorescent nucleoid assay; hypothermia;

    Sammanfattning : The effect of ionising radiation on cells can be modulated by several physico-chemical factors. The aim of this study was to investigate if hypothermic (sub-physiological) temperatures (2°C-28°C) may influence the effect of X-rays on cellular damage in human normal fibroblasts and in a human breast adenocarcinoma cell line, MCF-7.

  7. 25. Tools for the Advancement of Radiopharmaceutical Therapy

    Författare :Emma Mellhammar; Forskningsgruppen för Systemisk strålterapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiopharmaceutical therapy; Nuclear medicine; Monte Carlo simulation; Intratherapeutic preclinical PET; Alpha particles; Beta Particles; radionuclides; Radiobiology; γ-H2AX; Dosimetry;

    Sammanfattning : Radiopharmaceutical therapy is used to treat cancers and other diseases with radiolabeled pharmaceuticals. The treatment targets specific cells, and the emitted ionizing radiation cause cytotoxic damage. Dosimetry is performed to estimate the absorbed dose from the energy deposited in the body. LÄS MER
