Triglyceride level-influencing functional variants of the ANGPTL3, CILP2, and TRIB1 loci in ischemic stroke.

Stroke is a common multifactorial disease, and the third leading cause of death worldwide, which results in serious long-term mental and physical disability among survivors. The role of affected triglyceride metabolism in the development of ischemic stroke is under extensive investigations. Here, we examined three SNPs, rs12130333 located within the ANGPTL3 locus; rs16996148 residing at the CILP2 gene locus; and rs17321515 at the TRIB1 locus, which were originally reported in association with decreased triglyceride levels; therefore, we investigated their possible protective effect against the development of ischemic stroke.

Interaction between CTLA4 gene and IBD5 locus in Hungarian Crohn's disease patients.

Backgrounds And Aims: The IGR2198a_1 and IGR2096a_1 variants of the IBD5 region were found to be associated with Crohn's disease (CD) in the Hungarian population, while IGR2230a_1 does not seem to confer risk for the disease. In the present study, our aim was to investigate the statistical interaction of these three IBD5 polymorphisms with the +49 A/G substitution within the cytotoxic T lymphocyte antigen-4 (CTLA4) gene, detected previously as neutral gene variant in Hungarian IBD patients.

Methods: A total of 305 unrelated subjects with CD and 310 healthy controls were genotyped with PCR-RFLP methods.

Prevalent role of Akt and ERK activation in cardioprotective effect of Ca(2+) channel- and beta-adrenergic receptor blockers.

We studied cardioprotective as well as Akt and extracellular signal-activated kinase (ERK) activating effect of a Ca(2+) antagonist and a beta-adrenergic receptor blocker during ischemia-reperfusion, and compared these properties of the substances with that of a poly(ADP-ribose) polymerase (PARP) inhibitor used as a positive control throughout the experiments. Langendorff-perfused isolated rat hearts were subjected to 25 min global ischemia followed by 45 min reperfusion, and recovery of energy metabolism as well as functional cardiac parameters were monitored. Although to varying extents, all substances improved recovery of creatine phosphate, ATP, intracellular pH, and reutilization of inorganic phosphate.

Effect of antibiotic treatment on bacterial attachment to a DePuy Enduron orthopedic implant.

Background: The increasing incidence of bacterial infections in orthopedic surgery might be related to the increasing application of artificial devices. In most cases, bacteria multiply on the surface of implants in biofilms. Poor penetration of antibiotics, frequent necessity of prosthesis removal, chronic processes and financial costs emphasize the significance of preventive measures.

Effect of antibiotics on cell surface hydrophobicity of bacteria causing orthopedic wound infections.

Background: Despite antibiotic prophylaxis and treatment, the incidence of wound infections in orthopedic surgery is significant. Postoperative wound infection is a multifactorial process, which can be modified by several bacterial factors. Cell surface hydrophobicity of bacteria is a very important physicochemical feature, which has a great influence on the ability of bacteria to adhere to the surface of host cells or medical implants.
