36. Analysis of melanins
Sammanfattning : Mammalian melanins are of two major types, eumelanins and peheomelanins, which often occur together, then called mixed-type melanins. A method has been developed for analysing the various forms of melanins. LÄS MER
37. Involvement of Homologous Recombination in Response to Different Qualities of DNA Damage
Sammanfattning : The present studies aimed at elucidate the role of homologous recombination (HR) for the repair of different qualities of DNA damages and/or changes in chromatin structure induced by a variety of radiation qualities.Radiation qualities used to expose cells in culture ranged from non-ionizing radiation with extremely low frequency (ELF), of energies too low to disrupt chemical or molecular bonds, to radiation qualities with energies able to induce ionizations and break chemical bonds.

38. Central nervous system targets for micturition control
Sammanfattning : Normal urine storage and bladder emptying are controlled by the central (CNS) as well as the peripheral nervous system. Dysfunction of these mechanisms can lead to urinary incontinence. Urinary tract dysfunctions have symptomatically been treated mainly with drugs acting peripherally. LÄS MER
39. A study of potassium channel activation as a pharmacological principle for vasodilation of cerebral blood vessels
Sammanfattning : Increasing [K+]o is intimately coupled to progressive ischemia and reduced CBF. In isolated cerebral and mesenteric arteries, it was found that significant differences in the vascular responses to [K+]o exist. Among the species studied, human cerebral arteries were the most sensitive artery to increasing [K+]o. LÄS MER
40. Factors Contributing to Detrusor Overactivity - Obstruction, Hypertrophy and Afferent Nerve Stimulation
Sammanfattning : The consequences of bladder outlet obstruction (BOO) with respect to detrusor hypertrophy, structural and functional changes, and obstruction-induced detrusor overactivity were investigated in vivo and in vitro utilizing various animal models. Possible pathophysiological pathways and therapeutic approaches were tested by drug treatment and the use of knockout models. LÄS MER
