    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Ludwig Nilsson; [2019]
    Keywords : Biology and Life Sciences;

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Ashley Hulcoop; [2019]
    Keywords : Biology and Life Sciences;

    Abstract : 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. 3. Dose-response for predicting skin sensitization potency with the GARD®skin method

    University essay from Lunds universitet/Institutionen för Immunteknologi

    Author : Olivia Eliasson; [2019]
    Keywords : 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;

    Abstract : 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. READ MORE

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