  1. 16. Controlled release gel formulations and preclinical screening of drug candidates

    Författare :Tofeeq Ur-Rehman; Gerhard Gröbner; Mikael Elofsson; Åsa Gylfe; Martin Malmsten; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; poloxamer; drug delivery; micellization; DMSO; calorimetry; NMR. in situ gelation; chitosan; preclinical pharmacokinetics; type III secretion inhibitors; Physical chemistry; Fysikalisk kemi; Pharmaceutics; galenisk farmaci;

    Sammanfattning : Simple gel formulations may be applied to enhance the systemic and local exposure of potential compounds. The aim of this thesis is the development and characterization of controlled release formulations based on thermo-reversible poloxamer gels, which are suitable for novel drug delivery applications.

  3. 17. Pathophysiology and treatment of Takotsubo Syndrome - insights from preclinical studies

    Författare :Anwar Ali Gasim Elsied; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Takotsubo;

    Sammanfattning : ABSTRACT Background: Takotsubo syndrome (TTS), also recognized as “stress-induced cardiomyopathy (SIC)” and “broken heart syndrome”, is an acute cardiac failure syndrome characterized by transient regional ventricular akinesia or hypokinesia, and often presents similarly to acute myocardial infarction (AMI). In contrast to AMI, the characteristic regional myocardial akinesia in TTS does not involve a culprit coronary artery. LÄS MER

  4. 18. Preclinical Studies of the Melphalan Prodrug J1 for Cancer Therapy

    Författare :Malin Wickström; Joachim Gullbo; Rolf Larsson; Johan Hansson; Uppsala universitet; []
    Nyckelord :Pharmacology; Pharmacology; Chemotherapy; Melphalan prodrug; Cancer; Farmakologi;

    Sammanfattning : J1 (L-melphalanyl-L-p-fluorophenylalanyl ethyl ester) is a dipeptide derivative of the alkylating agent melphalan with increased cytotoxicity. In this thesis the preclinical pharmacology of J1 has been characterized.Our results show that J1 rapidly enters the cells, where melphalan is released by hydrolysis. LÄS MER

  5. 19. Translational studies of epithelial cancer

    Författare :Johanna Classon; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tumors stemming from specialized epithelial cells cause the most common cancer types and are among the leading causes of death in the western world. Although great strides have been made in early cancer detection, defining prognostic factors, and improving survival with novel treatments, cancers such as colorectal cancer and prostate cancer are incurable in their advanced stages.

  7. 20. Pulmonary Drug Absorption : In vitro and in vivo investigations of drug absorption across the lung barrier and its relation to drug physicochemical properties

    Författare :Ann Tronde; Gerrit Borchard; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; lung; pulmonary; drug delivery; inhalation; drug transport; pharmacokinetics; absorption; bioavailability; drug metabolism; preclinical; rat; in vivo; isolated and perfused lung; Caco-2; nebulization catheter; aerosol; physicochemical; peptide; efflux; FARMACI; PHARMACY; FARMACI; Biopharmaceutics; biofarmaci;

    Sammanfattning : Although, pulmonary drug delivery is a well established means for targeting of drugs to the lungs for the treatment of respiratory diseases as well as for the systemic delivery of volatile anesthetic agents, drug absorption kinetics in the lung have not been subjected to extensive research. The main objective of this thesis was to investigate drug absorption characteristics of the lung barrier, using the isolated and perfused rat lung model and in vivo pharmacokinetic studies in rats.
