Hyperglycaemia increases inflammatory cytokine concentration in the blood. Elevated levels of interleukin-18 (IL-18), a cytokine belonging to the interleukin-1 (IL-1) family, were recently reported in patients with Type 2 diabetes mellitus (DM2) and nephropathy. The aim of the present work was an examination of IL-18 concentration in the sera of elderly DM2(More)
UNLABELLED Lymphocyte-induced angiogenesis test (LIA) is a model of local graft-versus-host (GVH) reaction, marker of the earliest events resulting from activation of donor lymphocytes after contact with host semi-allogeneic histocompatibility antigens. The effect of in vivo oral administration of Aloe vera gel for 21 days to maternal strain (Balb/c) donor(More)
Satellite cells (SC) are present in all types of skeletal muscles. They can exhibit DNA replication and mitotic divisions throughout their life. Depending on the kind of muscle, a different number of SC is present. The aim of this study was to establish whether the differences in muscle metabolism are reflected in the quantitative ultrastructural evaluation(More)
Pentoxifylline (PTX), a methylxanthine derivative, is commonly and in most cases chronically used in patients suffering from peripheral vascular diseases. It increases erythrocyte flexibility, reduces blood viscosity and improves microcirculatory flow. Moreover, PTX has been found to enhance anticancer activity of some chemotherapeutic agents and ionizing(More)
The Hedgehog (HH) signaling pathway is involved in patterning and development of a variety of organ systems, including the nervous system, the skeletal system, the craniofacial structures, and the gastrointestinal tract. Recent evidence also implicates this signaling pathway in the postembryonic regulation of stem-cell number in epithelia and blood. The(More)
Angiogenesis, the process of new blood vessel formation, is the key event in the mechanism of several pathological processes including diabetic retinopathy. The physiological control of angiogenesis depends on the balance between stimulatory and inhibitory factors. Therefore, a number of anti-angiogenic approaches has been developed, many of them based on(More)
Chronic wounds are a significant socio-economic problem, thus, the improvement of the effectiveness of their treatment is an important objective for public health strategies. The predominant stage of the chronic wound is the inflammatory reaction which is associated with the damage of tissues, possibly due to the excessive secretion and activation of matrix(More)
Anticancer activity of many herbs was observed for hundreds of years. They act as modifiers of biologic response, and their effectiveness may be increased by combining multiple herbal extracts . PERVIVO, traditional digestive herbal remedy, contains some of them, and we previously described its antiangiogenic activity. Numerous studies documented anticancer(More)
Tuberous sclerosis (TSC) is an autosomal dominant disease, caused by mutations in TSC1 or TSC2 genes, encoding hamartin and tuberin, respectively. The clinical picture of the disease is connected with the formation of hamartomas, mainly in the heart, kidneys and the brain. In three types of brain lesions: cortical tubers, subependymal nodules and(More)
P remature development of microvascular and macrovascular disease is the most frequent complication of diabetes. It is responsible for diabetic retinopathy, nephropathy, and neuropathy (1). Moreover, diabetes leads to reduced collateralization in ischemic tissues, which causes impaired wound healing, exacerbation of peripheral limb ischemia, and a threeto(More)
