  1. 1. The Effect of Using DMSO as a Cosolvent for Ligand Binding Studies

    Master-uppsats, Lunds universitet/Biofysikalisk kemi

    Författare :Simon Birgersson; [2019]
    Nyckelord :Galectins; Nuclear Magnetic Resonance; NMR; Biophysical Chemistry; Relaxation; CPMG; ITC; Biofysikalisk Kemi; Kärnmagnetisk resonans; Technology and Engineering; Chemistry; Biology and Life Sciences;

    Sammanfattning : DMSO sees common application as a solvent for studies of synthetic molecules in biological systems, in fields such as drug design. Despite this, the possibility and nature of solvent interactions with both synthetic ligand and their target macromolecules is widely unexamined. LÄS MER

  2. 2. Flygmekanik i sidledsmanöver hos Svartvit flugsnappare (Ficedula hypoleuca)

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Ludwig Nilsson; [2019]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : There is not much research done regarding maneouvering flight on Birds. What has been done surrounding the area usually involves steady flight and not maneuvering. For the most part studies concern bats, insects or hummingbirds. LÄS MER

  3. 3. A Search for Neonicotinoid Binding Sites in the Optic Lobes of Honeybees and Blowflies

    Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Ashley Hulcoop; [2019]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Neonicotinoid insecticides are agonists to nicotinic acetylcholine receptors (nAChRs) in the brains of insects. At sub-lethal doses these chemicals cause behavioral abnormalities in several bee species, reducing overall fitness. nAChRs expressed in the optic lobes of insects bind neonicotinoids, thus may be involved in these behavioral changes.

  4. 4. Dose-response for predicting skin sensitization potency with the GARD®skin method

    Master-uppsats, Lunds universitet/Institutionen för Immunteknologi

    Författare :Olivia Eliasson; [2019]
    Nyckelord :Dose-response; In vitro assay; GARD; skin sensitization; allergic contact dermatitis; chemical sensitizers; hazard assessment; skin sensitization potency; immunotoxicology; Technology and Engineering; Biology and Life Sciences;

    Sammanfattning : Allergic contacts dermatitis is a major health problem in the world and the disease is caused by a type IV hypersensitivity to a small chemical called a hapten. These substances are common in cosmetics, perfumes, pharmaceuticals and house-hold products, and risk factors include both inherent factors and frequent or high exposure. LÄS MER

  5. 5. The impact of CRISPR/Cas9 generated mutations in pioneer transcription factors FOXA1 and GATA3 on oestrogen receptor function

    Master-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Miroslav Bobrik; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Breast cancer is the most common cancer among women and two thirds of all breast cancers are classified as oestrogen receptor positive. ER is a transcription factor that regulates gene expression and promote cell proliferation that is critical in mammary gland development, and its aberrant activity is commonly present in breast cancer.
