Human Fetuin-A Rs4918 Polymorphism and its Association with Obesity in Healthy Persons and in Patients with Myocardial Infarction in Two Hungarian Cohorts.

BACKGROUND Human fetuin A (AHSG) has been associated with the development of obesity, insulin resistance, type 2 diabetes mellitus, and atherosclerosis. Observations on the role of AHSG rs4918 single-nucleotide polymorphism are contradictory. We investigated the association between variants of rs4918 and parameters of obesity, lipid status, tumor necrosis factor-α (TNFα), adipokines (adiponectin, resistin, leptin), and insulin resistance in healthy persons and in patients with previous myocardial infarction.

Association of human fetuin-A rs4917 polymorphism with obesity in 2 cohorts.

Background: Previous studies have shown association of the multifunctional hepatic protein α2HS-glycoprotein/human fetuin A with insulin resistance, type 2 diabetes mellitus, metabolic syndrome, obesity, and atherosclerosis. Reports of contribution of α2HS-glycoprotein/human fetuin A rs4917 single-nucleotide polymorphism to the development of these pathologic processes are inconsistent. We aimed to investigate the association between variants of rs4917 and parameters of obesity, lipid status, the proinflammatory cytokine tumor necrosis factor α (TNF-α), adipokines (adiponectin, resistin), and insulin resistance in 2 cohorts.

Association of PPAR polymorphisms with cytokine levels in allergic rhinitis.

Our aim was to study the association of Pro12Ala and exon6 C161T polymorphisms of PPARgamma and intron7 G/C polymorphisms of PPAR-alpha with clinical symptoms, peak nasal inspiratory flow values, serum soluble TNF-alpha, TNF-R1, Fas, Fas ligand and IgE concentrations in patients with seasonal allergic rhinitis during and after pollen season. We performed a follow-up study of 66 Hungarian patients with seasonal allergic rhinitis and 180 healthy referent subjects. We used PCR-RFLP technique and ELISA.

Serum fetuin-A in metabolic and inflammatory pathways in patients with myocardial infarction.

Background: Although multifunctional glycoprotein α2HS-glycoprotein/human fetuin-A (AHSG) is involved in atherosclerosis, it is not clear whether high or low concentrations are more important. We studied the correlation of serum AHSG with adiponectin, leptin, resistin, C-reactive protein (CRP) and tumour necrosis factor-α (TNF-α) to see whether its metabolic effects or its involvement in subclinical inflammation are dominant in patients with established coronary disease.

Materials And Methods: In this cross-sectional study, AHSG concentration was determined in sera of 171 patients (age: 62 ± 6 years, mean ± SD) with previous myocardial STEMI infarction and normal renal function and 81 age-matched healthy controls by radial immunodiffusion.

Association of TLR-4 and TNF-alpha polymorphisms with clinical symptoms and cytokine levels in patients with allergic rhinitis.

Our objective was to determine the frequency of TNF-alpha -238, -308 G/A promoter and TLR-4 299 D/G and 399 T/I polymorphisms in healthy population and in patients with seasonal allergic rhinitis, and to examine its influences on serum TNF-alpha, TNF receptor-1, Fas, Fas-ligand, IgE levels and on clinical symptoms. A pilot study was performed in 66 patients with seasonal allergic rhinitis to ragweed pollen and 161 non-allergic subjects using PCR-RFLP technique and ELISA. Carriers of the -238A and -308G alleles have significantly higher TNF-alpha and IgE levels, clinical score values and lower peak nasal flow (PNIF) values during and after ragweed pollen season.

Optimizing color reproduction of a topometric measurement system for medical applications.

Integration of color information in 3D models acquired with a topometric measurement system opens a wide field of applications in medicine, e.g. prosthetics.

Modular optical topometric sensor for 3D acquisition of human body surfaces and long-term monitoring of variations.

Optical topometric 3D sensors such as laser scanners and fringe projection systems allow detailed digital acquisition of human body surfaces. For many medical applications, however, not only the current shape is important, but also its changes, e.g.
