Two missense mutations (A53T and A30P) in the gene encoding the presynaptic protein alpha-synuclein (asyn) are associated with rare, dominantly inherited forms of Parkinson's disease (PD) and its accumulation in Lewy bodies and Lewy neurites. As an initial step in investigating the role of asyn in the pathogenesis of PD, we have generated C57BL/6 transgenic(More)
We have analyzed the brain distribution of the rat 5-HT4 receptor mRNA. A receptor specific probe was used for in situ hybridization of rat brain sections. Abundant expression of the 5-HT4 receptor mRNA was observed in the olfactory system, striatum, medial habenula and the hippocampal formation, while faint or no specific signals could be detected in most(More)
A new technological approach for supplying hypoxic chronic wounds with oxygen is a moist wound treatment with aqueous solutions containing tissue compatible oxygen binders. This facilitates diffusion of oxygen, necessary for the healing process, from the surroundings (room air through an open-porous wound padding) into the ulcerous tissue. A product that is(More)
UNLABELLED Chronic wounds are an increasing problem in our ageing population and can arise in many different ways. Over the past decades it has become evident that sufficient oxygen supply is an essential factor of appropriate wound healing. Sustained oxygen deficit has a detrimental impact on wound healing, especially for patients with chronic wounds. This(More)
Conflict of interest: Some material and figures has been provided by SastoMed ABSTRACT Background: The improvement of oxygenation is gaining increasing attention as an important aspect in modern wound care. The aim of such complementary care is to improve and accelerate wound healing. Patients and Methods: A solution comprised of purified haemoglobin was(More)
Currently not much is known about the distribution and function of the phosphodiesterase type 7 (PDE-7) enzyme. Therefore, we carried out an extensive distribution analysis of the rat and human PDE-7 byin situ hybridization as well as RT-PCR. We isolated a partial rat cDNA clone that is highly homologous to the sequence of the human PDE-7 gene. RT-PCR(More)
BACKGROUND Although the underlying primary cause of chronic wounds may vary, a common etiology of this is a hypoxic or ischemic status of the affected tissue of the lower extremities. In particular, for rare diseases associated with disturbed blood flow a correlation between cause and effect is often diagnosed inappropriately. As a consequence, chronic(More)
Chronic leg ulcers can be a challenge to treat and long-term therapy a significant cost factor in western public health budgets. Objective wound assessment assays enabling selection of appropriate wound therapy regimes would be desirable. Oxygenation status in ulcer tissue has obtained increased attention as a relevant factor in wound healing. To increase(More)
Painful acute cysts in the natal cleft or lower back, known as pilonidal sinus disease, are a severe burden to many younger patients. Although surgical intervention is the preferred first line treatment, postsurgical wound healing disturbances are frequently reported due to infection or other complications. Different treatment options of pilonidal cysts(More)
