1. 11. Preclinical Development of New Alkylating Oligopeptides for Cancer Therapy

   Författare :Joachim Gullbo; Rolf Larsson; Peter Nygren; Staffan Eriksson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; pharmacology; oncology; chemistry; Melphalan derivatives; Farmakologi; Pharmacological research; Farmakologisk forskning;

   Sammanfattning : Oligopeptides can be used to carry cytotoxic agents in cancer chemotherapy, using tumour-associated proteins as the molecular target for selectivity. During the seventies and eighties Peptichemio, a cocktail of six alkylating oligopeptides carrying m-L-sarcolysin, was investigated in a wide variety of human malignancies. LÄS MER

3. 12. Pluripotent Stem Cells of Embryonic Origin : Applications in Developmental Toxicology

   Författare :Måns Jergil; Lennart Dencker; Aldert Piersma; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Embryonic stem cell; Microarray; Toxicogenomics; Valproic acid; Developmental toxicology; Teratogenicity; Neural tube defects; Histone deacetylase inhibitor; In vitro toxicology; Toxicology; Toxikologi; Toxicology; Toxikologi;

   Sammanfattning : General toxicity evaluation and risk assessment for human exposure is essential when developing new pharmaceuticals and chemicals. Developmental toxicology is an important part of this risk assessment which consumes large resources and many laboratory animals. LÄS MER

4. 13. Aspects of aqueous humor dynamics : Studies in vivo and in vitro

   Författare :Maria Samuelsson-Almén; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; Aqneous humor flow; intraocular pressure; adenylate cyclase; nonpigmented ciliary epithelium; pituitary adenylate cyclase-activating polypeptide; vasoactive intestinal polypeptide; dopamine; prostaglandin; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

   Sammanfattning : The purpose of the present investigation was to study the effects of PGF2α-l-isopropylester, some neuropeptides, and pharmacological agents on aqueous humor dynamics and intraocular pressure (IOP) in vivo and on adenylate cyclase activity in the nonpigmented ciliary epithelium (NPE) in vitro.Pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP) caused a dose-dependent increase in cAMP formation, indicating that the NPE contains receptors for PACAP and VIP coupled to adenylate cyclase activation.

5. 14. On the autonomic control of the lower urinary tract. Functional and morphological aspects in the normal and the inflamed urinary bladder

   Författare :Daniel Giglio; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muscarinic receptor; purinoceptor; adrenoceptor; nitric oxide; in vitro; in vivo; cystometry; Western blot; immunohistochemistry; cystitis; cyclophosphamide; urinary bladder; rat;

   Sammanfattning : The regulation of urinary bladder function involves interplay of signalling systems. Disturbances in any of the interactive systems may result in lower tract dysfunction, which is often apparent to the patient by urge to void or by incontinence, irrespectively of the cause to the lower tract syndrome.

7. 15. In vitro and in vivo studies of artemisinin endoperoxides

   Författare :Therese Ericsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Artemisinin; Artesunate; Breast cancer; Cytochrome P450; Dihydroartemisinin; Inhibition; LC-MS MS; Pharmacokinetics; Plasma; Saliva;

   Sammanfattning : Artemisinin and its semi-synthetic derivatives (eg. Artemether/ARM, artesunate/ARS, dihydroartemisinin/DHA) play an important role in combating malaria, and treatments containing an artemisinin derivative (artemisinin-based combination therapies, ACTs) are today the standard treatment worldwide for Plasmodium falciparum malaria.
