The main consequence of subarachnoid hemorrhage, for those who survive bleeding, is delayed, persistent vasospasm of intracranial conduit arteries which occurs between the third and seventh day after the insult and results in symptomatic brain ischemia in about 40% of cases. This vasospasm is considered to be a major cause of disability of post-SAH(More)
BACKGROUND Systemic lupus erythematosus (SLE) is an autoimmune disease, with multiple genetic and environmental factors involved in its etiology. The toll-like receptor 9 (TLR9) gene has been reported to have important roles in the development and progression of SLE. In this case-control study, the effect of TLR9 polymorphism on susceptibility to SLE was(More)
BACKGROUND Breast cancer is a multifactorial disease caused by complex interactions between genetic and environmental factors. Recently, a functional polymorphism, MDM2 285G>C (rs117039649), has been discovered. This polymorphism antagonizes the effect of the 309T>G (rs2279744) polymorphism on the same gene, resulting in decreased MDM2 transcription. (More)
The protein tyrosine phosphatase non-receptor 22 (PTPN22) 1858 C>T poly-morphic variant gene (rs2476601) displays an association with systemic lupus erythematosus (SLE) and other autoimmune diseases. However, its contribution to SLE has been found to be disputable. We therefore examined the association of PTPN22 1858 C>T polymorphism with susceptibility to(More)
Accumulation of squalene in the CNS is observed after administration of tellurium and squalene has been proposed to be a mediator of tellurium encephaloneuropathy. The aim of this study was to investigate the effects of squalene on the central and peripheral nervous systems in rat at the ultrastructural level. Squalene was administered at a dose of 20 g/kg(More)
Male Wistar rats were subjected to intraperitoneal (i.p.) streptozotocin (STZ) administration (85 mg/kg) to evoke diabetes. Cerebral ischaemia was produced by injection of 0.03 ml of air into the left carotid followed by bilateral common carotid ligation. We studied the effect of application of two antioxidants--coenzyme Q10 (CoQ10, 10 mg/kg b.w., i.p. for(More)
To investigate the influence of squalene on the nervous system, adult male Wistar rats were injected with squalene subcutaneously with 20 g/kg of the body weight for 4 consecutive days. After 7 or 30 days from the initiation of the experiment, brain and ischiadic nerves were harvested for electron microscopy. Squalene affected mostly PNS targeting Schwann(More)
There is conflicting evidence on the contribution of the MCP-1 -2518 A>G (rs 1024611) polymorphism to SLE incidence and clinical manifestations. We examined the prevalence of the MCP-1 -2518 A>G polymorphism in SLE patients (n = 199) and controls (n = 250) in Poland. We did not observe a significant difference in the distribution of MCP-1 -2518 A>G(More)
There is one study on the association of the CD40 G > T (rs4810485) single nucleotide polymorphism (SNP) as a risk factor of systemic lupus erythematosus (SLE). Therefore, we studied the prevalence of the CD40 G > T SNP in patients with SLE (n = 261) and controls (n = 545) in a Polish population. We did not find significant differences between the CD40 G >(More)
Statins are competitive inhibitors of 3-hydroxy-3-methylglutaryl-coenzyme A reductase, a rate-limiting step of the mevalonate pathway. The pleiotropic effects of statins may be due to inhibition of cholesterol synthesis, as well as decreased availability of several biologically important intermediate components of the mevalonate pathway, including two(More)
