  1. 1. Essays on Land Lease Markets, Productivity, Biodiversity, and Environmental Variability

    Författare :Mintewab Bezabih; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; JEL-codes: C7; C21; C35; C61; C88; C93; D00; D2; Q02; Q12; Q15; Q29; Q51;

    Sammanfattning : Paper 1: Tenure Insecurity, Transaction Costs in the Land Lease Market and Implications for Gendered Productivity Differentials This study assesses the link between land leasing behavior and productivity differentials between male and female-headed households. A double-moral hazard model allows us to show that the landlord’s tenure insecurity leads to a sub-optimal level of effort on the tenant’s part, via its impact on the likelihood of contract renewal.

  4. 3. Ligands of the Angiotensin II Type 2 Receptor : Exploring structure and function of the AT2R ligand C38

    Författare :Rebecka Isaksson; Mats Larhed; Annette Bayer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiotensin II type 2 receptor; AT2R antagonists; sulfonyl carbamates; bicyclic amides; metabolic stability; functional activity assay; pharmacological profile; medicinal chemistry; structure-activity relationship; Medicinal Chemistry; Läkemedelskemi;

    Sammanfattning : The renin-angiotensin-aldosterone-system (RAAS) control blood-pressure regulation, exerted by the main effector peptide angiotensin II (AngII) binding the angiotensin II type 1 receptor (AT1R). While hypertension is the most known disease caused by over-activity in RAAS, several proteins in the system exhibit protective functions. LÄS MER

  5. 4. Enzymes in different pathways of bile acid biosynthesis

    Författare :Catrin Furster; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Biochemistry; biokemi;

    Sammanfattning : Enzymes catalyzing side chain hydroxylations and dehydrogenation/isomerization in different pathways of bile acid biosynthesis were studied.Pig liver mitochondrial sterol 27-hydroxylase (CYP27A) was found to catalyze 24- and 25-hydroxylation of cholesterol in addition to the known 27-hydroxylation.

  7. 5. Intravenous morphine after gynecological surgery : pain relief, endocrine and immune respone

    Författare :Marianne Eriksson-Mjöberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Anaesthesia: general; epidural. Postoperative pain: PCA; morphine; bupivacaine. Hormones: adrenocortical steroids; estrogens. Immune response: Interleukin-6.;

    Sammanfattning : Background: We need more efficient methods to alleviate postoperative pain and reduce endocrine / immune stress response. Subjects and methods: Patient controlled analgesia (PCA) with iv morphine was evaluated with respect to pain relief and endocrine / immune response to surgical trauma in 130 patients undergoing gynecological surgery.
