Abstract
In 2022, according to the World Health Organization (WHO) report, overweight and obesity have reached epidemic proportions in the WHO European Region, affecting almost 60% of adults. Based on the assessment of BMI (Body Mass Index), a group of 56 women aged 25-45 years (31 women group A average BMI 34.9 ± 4.86 kg/m2 and 25 women group B average BMI 33.4 ± 4.02 kg/m2) were qualified for the study. In a multi-center, two-arm, parallel, non-randomized study, two types of weight-reduction diets (A and B) were used over a 3-month period. In group A, a standard low-energy diet was used with individually adjusted caloric intake of 1100-1300 kcal, with an increase in the amount and frequency of consumption of sauerkraut and groats and a daily intake of fermented milk drinks (300-400 g), fermented cucumbers (100 g), mineral water (1 L) and cod liver oil (5 mL). In group B, a standard low-energy diet with individually adjusted caloric intake of 1100-1300 kcal with daily intake of fermented milk products (150 g), highly mineralized water (0.5 L), once a week fermented cucumbers, and once a week buckwheat groats was used. The following measurements were taken: body weight, body fat mass, water content, body height, waist circumference, and hip circumference. Body weight and body composition were measured using the Tanita MC-780 MA and TANITA BC-601 analyzer using the bioelectric bioimpedance method. The stool samples were analyzed in the microbiology laboratory where quantification of Bifidobcaterium spp., Bacteroides spp., Faecalibacterium prausnitzii species, Akkermansia muciniphila and total bacterial count (TBC) was performed. Under the influence of the introduced nutritional intervention, a statistically significant reduction in body weight, body fat, waist circumference, and hip circumference was demonstrated after 3 months. Under the influence of weight reduction, as well as dietary changes, there was an increase in the number of Akkermansia muciniphila bacteria in the women studied. The low-energy diet containing sources of natural prebiotics and probiotics had a more favorable effect on the number of Faecalibacterium prausnitzii bacteria compared to the standard diet.

Abstract
BACKGROUND Novel derivatives of benzo[b]furan were found to be highly toxic towards human chronic myelogenous (K562), acute myelogenous (HL-60) and acute lymphoblastic (MOLT-4) leukemia cells. OBJECTIVE The objective was the characterization of the biological activity of novel benzofurans (influence on apoptosis, mitogen-activated protein kinases and on the cell cycle). Cellular protein(s) targeted by test benzofurans and mechanism of action were identified. METHODS The methods utilized in the study were chemical synthesis, fluorescence assays, flow cytometry, gene expression by DNA microarray and real-time RT-PCR, western blotting, cytotoxicity assays, pull-down assay, mass spectroscopy, in vitro polymerization of tubulin, molecular docking. RESULTS 1,1'-[3-(bromomethyl)-5,6- dimethoxy-1-benzofuran-2,7-diyldiethanone (1) and methyl 4-bromo-6- (dibromoacetyl)-5-hydroxy-2-methyl-1-benzofuran-3-carboxylate (2) induced apoptosis in K562 and MOLT-4 cells. The profiling of gene expression revealed that 1 and 2 increased the expression of proapoptotic genes involved in both receptor (TNFRSF 10A, TNFRSF 10B, CASP8) and mitochondrial (BAX, BID, NOXA, APAF1) pathways of apoptosis. Test benzo[b]furans activated c-Jun N-terminal kinase (JNK) and p38 kinase in K562 cells. Tubulin was identified as a protein target for benzo[b]furans in pull-down experiments with biotinylated 2. Test benzo[b]furans inhibited polymerization of tubulin monomers in vitro, decreased the level of cellular microtubules and arrested cells in a G2/M phase. Molecular docking suggests that benzo[b]furans 1 and 2 bind to tubulin via colchicine binding pocket and the complex is stabilized mainly by hydrophobic interactions. CONCLUSION Novel benzo[b]furans with anti-microtubule activity were identified. They induce apoptosis in cancer cells and cause G2/M cell cycle arrest. Biological activity of 1 and 2 makes them potential lead compounds for development as anticancer drugs.

Abstract
The aim of current bone biomaterials research is to design implants that induce controlled, guided, successful, and rapid healing. Titanium implants are widely used in dental, orthopedic, and reconstructive surgery. A series of studies has indicated that cells can respond not only to the chemical properties of the biomaterial, but also, in particular, to the changes in surface topography. Nanoporous materials remain in focus of scientific queries due to their exclusive properties and broad applications. One such material is nanostructured titanium oxide with highly ordered, mutually perpendicular nanopores. Nanoporous anodic titanium dioxide (TiO2) films were fabricated by a three-step anodization process in propan-1,2,3-triol-based electrolyte containing fluoride ions. Adipose-derived stem cells offer many interesting opportunities for regenerative medicine. The important goal of tissue engineering is to direct stem cell differentiation into a desired cell lineage. The influence of nanoporous TiO2 with pore diameters of 80 and 108 nm on cell response, growth, viability, and ability to differentiate into osteoblastic lineage of human adipose-derived progenitors was explored. Cells were harvested from the subcutaneous abdominal fat tissue by a simple, minimally invasive, and inexpensive method. Our results indicate that anodic nanostructured TiO2 is a safe and nontoxic biomaterial. In vitro studies demonstrated that the nanotopography induced and enhanced osteodifferentiation of human adipose-derived stem cells from the abdominal subcutaneous fat tissue.

Abstract
We aimed to assess the prevalence of diabetic retinopathy (DR) in adult patients with GCK-MODY and HNF1A-MODY in Poland and to identify biochemical and clinical risk factors associated with its occurrence.We examined 74 GCK mutation carriers, 51 with diabetes and 23 with prediabetes, respectively, and 63 patients with HNF1A-MODY. Retinal photographs, 12 for each patient, were done by a fundus camera. Signs of DR were graded according to the DR disease severity scale. Statistical tests were performed to assess differences between the groups and logistic regression was done for the association with DR.The mean age at examination was 34.5±14.8 and 39.9±15.2 in the GCK-MODY and HNF1A-MODY groups, respectively. Mild nonproliferative DR (NPDR) was found in one patient with the GCK mutation and likely concomitant type 1 diabetes, whereas DR was diagnosed in 15 HNF1A-MODY patients: 9 with proliferative, 3 with moderate NPDR and 2 with mild NPDR. In univariate logistic regression analysis in the HNF1A-MODY group, significant results were found for diabetes duration, fasting glycemia, HbA1c, arterial hypertension, age at the examination, and eGFR. The strongest independent predictors of DR in HNF1A-MODY were markers of glucose control: HbA1c (OR: 2.05, CL%95: 1.2-3.83, p=0.01) and glucose (p=0.006, OR: 1.40, CL%95: 1.12-1.83) analyzed in 2 separated models. Additionally, arterial hypertension independently predicted DR (OR: 9.06, CL%95: 1.19-98.99, p=0.04) in the model with HbA1c as glycaemic control marker.In conclusion, DR of any degree was not present in our GCK-MODY group, while in spite of young age almost every fourth subject with HNF1A-MODY showed signs of this complication.

Abstract
INTRODUCTION Low Carbohydrate High Protein diet represents a popular strategy to achieve weight loss. OBJECTIVE The aim of this study was to characterize effects of low carbohydrate, high protein diet (LCHP) on atherosclerotic plaque development in brachiocephalic artery (BCA) in apoE/LDLR-/- mice and to elucidate mechanisms of proatherogenic effects of LCHP diet. MATERIALS AND METHODS Atherosclerosis plaques in brachiocephalic artery (BCA) as well as in aortic roots, lipoprotein profile, inflammation biomarkers, expression of SREBP-1 in the liver as well as mortality were analyzed in Control diet (AIN-93G) or LCHP (Low Carbohydrate High Protein) diet fed mice. RESULTS Area of atherosclerotic plaques in aortic roots or BCA from LCHP diet fed mice was substantially increased as compared to mice fed control diet and was characterized by increased lipids and cholesterol contents (ORO staining, FT-IR analysis), increased macrophage infiltration (MOMA-2) and activity of MMPs (zymography). Pro-atherogenic phenotype of LCHP fed apoE/LDLR-/- mice was associated with increased plasma total cholesterol concentration, and in LDL and VLDL fractions, increased TG contents in VLDL, and a modest increase in plasma urea. LCHP diet increased SCD-1 index, activated SREBP-1 transcription factor in the liver and triggered acute phase response as evidence by an increased plasma concentration of haptoglobin, CRP or AGP. Finally, in long-term experiment survival of apoE/LDLR-/- mice fed LCHP diet was substantially reduced as compared to their counterparts fed control diet suggesting overall detrimental effects of LCHP diet on health. CONCLUSIONS The pro-atherogenic effect of LCHP diet in apoE/LDLR-/- mice is associated with profound increase in LDL and VLDL cholesterol, VLDL triglicerides, liver SREBP-1 upregulation, and systemic inflammation.

Abstract
Introduction Centrifugation is an essential step for plasma preparation to remove residual elements in plasma, especially platelets and platelet-derived microparticles (PMPs). Our working hypothesis was that centrifugation as a preanalytical step may influence some coagulation parameters. Materials and methods Healthy young men were recruited (N = 17). For centrifugation, two protocols were applied: (A) the first centrifugation at 2500 x g for 15 min and (B) at 2500 x g for 20 min at room temperature with a light brake. In protocol (A), the second centrifugation was carried out at 2500 x g for 15 min, whereas in protocol (B), the second centrifugation involved a 10 min spin at 13,000 x g. Thrombin-antithrombin (TAT) and plasmin-antiplasmin (PAP) complexes concentrations were determined by enzyme-linked immunosorbent assays. PMPs were stained with CD41 antibody and annexin V, and analyzed by flow cytometry method. Procoagulant activity was assayed by the Calibrated Automated Thrombogram method as a slope of thrombin formation (CAT velocity). Results Median TAT and PAP concentrations did not differ between the centrifugation protocols. The high speed centrifugation reduced the median (IQR) PMP count in plasma from 1291 (841-1975) to 573 (391-1010) PMP/µL (P = 0.001), and CAT velocity from 2.01 (1.31-2.88) to 0.97 (0.82-1.73) nM/min (P = 0.049). Spearman’s rank correlation analysis showed correlation between TAT and PMPs in the protocol A plasma which was (rho = 0.52, P < 0.050) and between PMPs and CAT for protocol A (rho = 0.74, P < 0.050) and protocol B (rho = 0.78, P < 0.050). Conclusion Centrifugation protocols do not influence the markers of plasminogen (PAP) and thrombin (TAT) generation but they do affect the PMP count and procoagulant activity.

Abstract
Barth syndrome (BTHS) is an X-linked recessive disease primarily affecting males. Clinically, the disease is characterized by hypertrophic or dilated cardiomyopathy, skeletal myopathy, chronic/cyclic neutropenia, 3-methylglutaconic aciduria, growth retardation and respiratory chain dysfunction. It is caused by mutations in the TAZ gene coding for the tafazzin protein which is responsible for cardiolipin remodeling. In this work, we present a novel pathogenic TAZ mutation c.83T>A, p.Val28Glu, found in mosaic form in almost all female members of a Polish family. Sanger sequencing of DNA from peripheral blood and from epithelial cells showed female mosaicism in three generations. This appears to be a new mechanism of inheritance and further research is required in order to understand the mechanism of this mosaicism. We conclude that BTHS genetic testing should include two or more tissues for women that appear to be noncarriers when blood DNA is initially tested. The results of our study should not only be applicable to BTHS families, but also to families with other X-linked diseases.

Abstract
A novel inorganic nanocomposite material, called BOA, which has the form of small building blocks composed of gold nanoparticles embedded in a polyoxoborate matrix, is presented. It is demonstrated that cotton wool decorated with the BOA nanocomposite displays strong antibacterial activity toward both Gram-positive and -negative bacteria strains. Importantly, the modified cotton does not release any toxic substances, and the bacteria are killed upon contact with the fibers coated with the BOA. Toxicity tests show that the nanocomposite--in spite of its antiseptic properties--is harmless for mammalian cells. The presented method of surface modification utilizes mild, environmentally friendly fabrication conditions. Thus, it offers a facile approach to obtain durable nontoxic antiseptic coatings for biomedical applications.

Abstract
BACKGROUND Hypertension during pregnancy is a heterogeneous group of disorders with elevated blood pressure with or without proteinuria. The multiple researches are held on the subject of a genetic conditioning of preeclampsia and pregnancy induced hypertension. OBJECTIVES The study was designed to evaluate the impact of the single nucleotide polymorphism (SNP) rs7579169 on hypertension disorders in pregnancy, especially on PE and PIH as well as on the perinatal outcome. METHODS It is a case-control study. The study included 104 women with uncomplicated pregnancies in the control group and 75 pregnant women with hypertension disorders in the study group, hospitalized in the Perinatology and Obstetrics Department of the University Hospital in Cracow. Genomic DNA was extracted from peripheral blood leukocytes and SNP rs7579169 was genotyped from all patients. We analyzed the genotypes distribution and allele frequencies of polymorphism rs7579169 and its association with perinatal outcome in all groups. A p-value<0.05 was considered as significant. RESULTS Clinical evaluation included standard anthropometric measures like weight and height for the calculation of the body mass index in the beginning and in the end of the pregnancy, blood pressure, time and a method of delivery, birth weight, Apgar score. The heterozygote CT was associated with a 4.5-fold increased risk of preeclampsia in pregnant patients. The presence of TT genotype significantly increased the risk of intrauterine growth restriction (<10 percentile). CONCLUSIONS The study show probable impact of SNP rs7579169 on pregnancy, but further studies on larger groups are needed.

Abstract
The number of overweight and obese people is increasing at an alarming rate, especially in the developed and developing countries. Obesity is a major risk factor for diabetes, cardiovascular disease, and cancer, and in consequence for premature death. The development of obesity results from the interplay of both genetic and environmental factors, which include sedentary life style and abnormal eating habits. In the past few years a number of events accompanying obesity, affecting expression of genes which are not directly connected with the DNA base sequence (e.g. epigenetic changes), have been described. Epigenetic processes include DNA methylation, histone modifications such as acetylation, methylation, phosphorylation, ubiquitination, and sumoylation, as well as non-coding micro-RNA (miRNA) synthesis. In this review, the known changes in the profile of DNA methylation as a factor affecting obesity and its complications are described.

BACKGROUND AND AIMS Elevated levels of circulating microparticles (MPs) have been reported in patients with acute myocardial infarction (AMI) and coronary artery disease. Platelet activation and inflammation have been recognized during AMI and stable angina (SA). We hypothesize that the origin and count of MPs in AMI and SA patients are related to markers of inflammation and platelet activation. METHODS Platelet, monocytes and endothelial MPs and surface P-selectin were determined in 12 AMI patients, 10 SA patients and 9 controls by flow cytometry. Plasma P-selectin, CD40 ligand (sCD40L) and interleukin 6 (IL-6) levels were evaluated by ELISA methods. RESULTS The total MP count was compared in control subjects, AMI, and SA patients: 12,765 (8465) vs. 38,750 (11,931) vs. 29,715 (12,072) counts/μl (p = 0.01), respectively. Patients with AMI displayed higher levels of total and platelet origin- tissue factor-positive (CD42/CD142) MPs than patients with SA: 72.8 (6.2) vs. 56.2 (6.4) %, p = 0.001. Levels of soluble P-selectin were significantly elevated in patients with AMI as compared to SA patients: 146 (6.5) vs. 107 (2.7) ng/mL, p = 0.005; significant correlation between total MP count and relative number of CD34, CD51, CD42-positive MPs, and the P-selectin expression was observed in patients with AMI. CONCLUSIONS Platelet activation in AMI is associated with increased generation of MPs not only from platelets, but also monocytes and endothelial cells. It suggests that interactions between platelets, monocytes and endothelial cells play an important role in the pathogenesis of myocardial ischemia.

Abstract
MicroRNAs (miRNAs) are a family of small, noncoding RNAs that repress gene expression at the post-transcriptional level. Over 700 miRNAs have been identified in the human genome, of which 20% to 30% regulate human protein-coding genes. Functional in vitro studies have shown that miRNAs are critical for endothelial cell gene expression and function. miRNAs were found in atherosclerosis, cardiac hypertrophy, arterial hypertension, coronary artery disease, diabetes, and inflammatory diseases. We review the current knowledge about the role of miRNAs in endothelial cells with emphasis on the regulation of cellular senescence, angiogenesis, and vascular inflammation. It has been shown that miR-34a, miR-217, miR-200, miR-146c, and miR-181a are responsible for the regulation of cell stress and proliferation processes. Proangiogenic factors include miR-130a, miR-210, miR-424, miR-17-92, miR-27-b, let-7f, and miR-217, while miR-221 and miR-222 have antiangiogenic properties. Other known miRNAs, including miR-31, miR17-3p, miR-155, miR-221, miR-222, and miR-126, are important factors in the regulation of vascular inflammation. Studies show that miRNA expression analysis can be used in the diagnosis and treatment of various diseases; however, additional research is needed before it is used in routine clinical setting.

Abstract
Humanin (HN) is a newly discovered 24-amino acid peptide, which may suppress neuronal cell death. HN cDNA includes an open reading frame (HN-ORF) of 75 bases located 950 bases downstream of the 5' end of the HN cDNA. It has been demonstrated that HN cDNA is 99% identical to the mitochondrial DNA (mtDNA) sequence. HN homologs have been identified as expressed sequence tags (ESTs) in both rats and nematodes. Certain regions that are homologous to the HN cDNA exist on human chromosomes. HN forms homodimers and multimers and this action seems to be essential for peptide function. HN acts as a ligand for formyl peptide receptor-like 1 (FPRL1) and 2 (FPRL2). It has been demonstrated that HN plays a protective role through its antiapoptotic activity that interferes with Bax activation, which suppresses Bax-dependent apoptosis. HN has also been shown to suppress the c-Jun N-terminal kinase (JNK) and ASK/JNK-mediated neuronal cell death. Several studies have also confirmed that HN could be important in the prevention of angiopathy-associated Alzheimer's disease dementia, diseases related to mitochondrial dysfunction (MELAS), and other types of β-amyloid accumulation-associated neurodegeneration. Avery recent study demonstrated a pluripotent cytoprotective effect and mechanisms of HNs in cells not from the CNS, such as germ cells or pancreatic β-cells, and the potent physiological consequences that result from HN interaction with IGFBP3 and STAT3. In vivo studies suggest that HN may also protect against cognitive impairment due to ischemia/reperfusion injury.

Abstract
Adiponectin, a protein secreted by adipose tissue but present at low levels in obesity, is now widely recognized as a key determinant of insulin sensitivity and of protection against obesity-associated metabolic syndrome. The adiponectin gene is very polymorphic and several of its variants contribute to adiponectin level, function and are associated with metabolic syndrome phenotypes. The results differ ethnically. The association of identified variants with obesity and its consequences, type 2 diabetes and cardiovascular disease is reviewed. This data may enable patients at greater risk of the adverse effects of obesity to be identified and, as such, benefit from more targeted therapy and prevention.

Abstract
Nutrigenomics is a promising multidisciplinary field that focus on studying the interactions between nutritional factors, genetic factors and health outcomes. Its goal is to achieve more efficient individual dietary intervention strategies aimed at preventing disease, improving quality of life and achieving healthy aging. Somehow, nutrigenomics has been used for decades in certain rare monogenic diseases such as phenylketonuria. It has the potential to provide a basis for personalized dietary recommendations based on the individual's genetic makeup in order to prevent common multifactorial disorders (such as metabolic syndrome) decades before their clinical manifestation. Preliminary results regarding gene-diet interactions in many diseases are for the most part inconclusive because of the limitations of current designs. Success in this area will require the integration of various disciplines (e.g. biotechnology, medicine, biology, economics) and will require investigators to work on ethnic groups. This knowledge should lead to successful dietary recommendations partly based on genetic factors that may help to reduce disease risk more efficiently than the current universal recommendations based mainly on epidemiological studies. We discuss nutrigenomic issues and show examples for this new, with a wide research area, field of science.

Abstract
Adiponectin (also called AdipoQ, gelatin-binding protein 28, Acrp30) is a novel adipocytokine with important metabolic effects. It is physiologically released from adipose tissue and circulates in serum as a hexamer and larger multimeric structure of high molecular weight. Serum level of the protein correlates with systemic insulin sensitivity. Recently adiponectin receptors AdipoR1 and AdipoR2 have been discovered by expression cloning. AdipoR1 is abundantly expressed in skeletal muscles, whereas AdipoR2 is predominantly expressed in the liver. Marked expression of mRNA for AdipoR1 and AdipoR2 has been lately reported in pancreatic beta cells. Both of the receptors activate AMPK and PPAR alpha metabolic pathways leading to an increase in fatty acid oxidation, glucose uptake and a decreased rate of gluconeogenesis, thus enhancing insulin sensitivity. Moreover effects of adiponectin mimic many metabolic actions of insulin such as augmenting blood flow and glucose disposal in NO-dependent manner. The precise mechanism of regulation of plasma adiponectin level is unknown. Recently the mechanism of transcriptional activation of adiponectin gene via PPAR gamma was described. Its level seems to be decreased by TNFalfa and beta-adrenergic agonists. Furthermore there is increasing evidence that some genetic variants in the adiponectin gene may be associated with its ethnical differences in level as well as its likely clinical consequences. Hipoadiponectynemia is associated with obesity, metabolic syndrome, diabetes type 2, cardiovascular disease, lipodystrophy in AIDS. In patients with chronic renal failure, anorexia nervosa plasma adlponectin level is increased. Weight loss and therapy with thlazolidinediones are proved to enhance endogenous adlponectin production in humans. In summary, the ability of adiponectin to increase insulin sensitivity in conjunction with its anti-inflammatory and antiatherogenic properties have made this novel adipocytokine a promising therapeutic tool for the future, especially in individuals with low plasma levels of adiponectin.

Abstract
BACKGROUND Previous studies have suggested that genetic variation in the beta2 (b2-AR) and beta3 (b3-AR) adrenergic receptor genes are associated with obesity and insulin resistance. The aim of this study was to evaluate the influence of beta2 (Gln27>Glu) and beta3 (Trp64>Arg) adrenoreceptor gene polymorphisms on BMI and carbohydrate-lipid metabolism in Polish obese families. MATERIAL/METHODS 122 persons (84 women, 38 men) from 40 obese families (BMI 33.5I7.7) were included. PCR-RFLP analysis of genotype was plotted against anthropometric parameters and the results of glucose and lipid oral tolerance tests. Venous blood samples were analysed for concentrations of glucose, insulin, free fatty acids, triglycerides, total cholesterol, HDL-chol, LDL-chol, leptin, and vWF. RESULTS We found 39% Glu27 with 8% Arg64 allele frequencies. The blood glucose and insulin concentration during OGTT and blood FFA and TG level during OLTT was lower in patients with the Glu/Glu b2-AR polymorphism than Glu/Gln and Gln/Gln. In the obese patients the same effect was observed; however, the percent of fat body mass, leptin concentration, and BMI was higher in this group. Patients with the Trp/Trp polymorphism in the b3-AR gene were characterized by higher glucose and insulin concentration during OGTT and higher blood concentration of FFA and TG during OLTT. These results were independent of BMI value. CONCLUSIONS The b2-AR 27Glu and b3-AR 64Arg alleles have a protective effect against metabolic disorders in obese families from southern Poland.

Abstract
Tumour necrosis factor alpha (TNF-alpha), acting as a modulator of gene expression in adipocytes, has been linked to the development of insulin resistance and obesity. The aim of this study was to investigate whether the A/G variation at position -308 in the TNF-alpha promoter influences the body weight, insulin resistance, and postprandial lipaemia in Polish Caucasians. One hundred twenty one subjects, 38 men and 83 women, representing 40 obese families, were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). TNF-1 (GG) and TNF-2 (GA and AA) allele carriers were compared with respect to body mass index, fat/lean body mass composition, waist-to-hip ratio, as well as fasting lipids, glucose, leptin, and insulin fasting, and during the oral glucose tolerance test (4 points within 2 hours) and oral lipid tolerance test (OLTT; 5 points within 8 hours). The insulin sensitivity indices HOMA-IR (homeostasis model assessment of insulin resistance), ISI-COMP (whole body insulin sensitivity index), ISI-HOMA (hepatic insulin sensitivity), and DELTA (early secretory response to an oral glucose load) were calculated. We detected 64 GG, 56 GA, and 1 AA genotypes. Significant increases of insulin resistance parameters in obese female TNF-2 allele carriers were observed (significantly increased HOMA-IR and decreased ISI-HOMA, ISI-composite). The male TNF-2 carriers were characterised by significantly increased levels of triglyceride and free fatty acids during OLTT as well as fasting glucose. The A/G variation at position -308 in the promoter region of the TNF-alpha gene could be an important genetic factor predisposing to insulin resistance in obese women and increased levels of glucose, triglyceride, and free fatty acids in men.

Abstract
The aim of the study was to examine the allelic frequency of the -3826A > G mutation of UPC1 in patients with familiar obesity and to investigate putative association of this polymorphism with metabolic disorders. One hundred and eighteen overweight /obese patients participated in the study. The UCP1 polymorphism was determined by RFLP. Glucose, lipid, insulin and leptin levels were measured both during OGTT and OLTT. The majority of patients had a homozygous A/A genotype (51,38%), while 14,68% had a G/G genotype. We found no significant association of the G allele with either BMI or glucose tolerance. Patients with the homozygous G/G genotype had significantly higher fasting levels of TG (p < 0.04) and decreased levels of HDL-cholesterol (p = 0,004). They also had an increased concentration of FFA and the rise of TG levels during the OLTT compared to controls was significant (p = 0,058). In addition, the carriers of the G/G genotype had the lowest insulin levels both during OGTT and OLTT. In our study we have demonstrated that the -3826A > G polymorphism of UCP1 does not play a major role in the development of obesity and/or disturbances of glucose metabolism. However, the increased levels of TG and FFA and decreased levels of HDL observed in carriers of the G allele suggest FFA-induced impairment of the HDL turnover and disturbance of the beta-cell function, both of which are risk factors for endothelial injury.

Abstract
The theories formulated to explain atherogenesis evolved from simple vessel wall lipid accumulation assumption to endothelial dysfunction with adverse vascular wall remodelling hypothesis. The theory that has been accepted lately integrates the former hypotheses and allows for introducing the local immunological activation concept. This immunological activation is initiated by negatively charged and oxidatively modified lipids (e.g. oxPAPC) and their complexes with proteins (like beta 2-GP I). Antibodies and cellular response against chaperonins: HSP 60 and their analogues from bacterial pathogens such as HSP 65, GroEi etc.) as well as release of cytokines, adhesion molecules and inflammatory mediators (CD 40/CD 40-L, IL 15, IFN gamma, IL 1 beta, TNF alpha) also take part in the process. Another important element of atherogenesis is the pathological angiogenic response within the plaque connected with the expression of angiogenic growth factors (such as VEGF, bFGF and PDGF), metallo-proteinases and local hemostasis regulators. This complex activation of local inflammatory and immunological process initiates such phenomena as development of unstable plaque, vascular remodelling, vessel lumen constriction and ischemic, thromboembolic complications of atherosclerosis.

Abstract
The regulation of vascular wall homeostasis by nitric oxide (NO) generated by endothelium is being intensively studied. In the present paper, the involvement of NO in the vascular endothelial growth factor (VEGF), insulin or leptin-stimulated proliferation of human endothelial cells (HUVEC) was measured by [3H]thymidine or bromodeoxyuridine incorporation. VEGF and insulin, but not leptin, increased NO generation in HUVEC, as detected with ISO-NO electrode. Proliferation of HUVEC induced by leptin was not changed or was higher in the presence of N(omega)-nitro-L-arginine methyl ester (L-NAME) a nitric oxide synthase (NOS) inhibitor. In contrast, L-NAME blunted the proproliferative effect of VEGF and insulin. Furthermore, we demonstrated that, in human arterial smooth muscle cells (hASMC) transfected with endothelial NOS (eNOS) gene, the generation of biologically active VEGF protein was NO-dependent. Inhibition of NO generation by L-NAME decreased the synthesis of VEGF protein and attenuated HUVEC proliferation induced by conditioned media from transfected hASMC. Endothelium-derived NO seems to participate in VEGF and insulin, but not leptin, mitogenic activity. Additionally, the small amounts of NO released from endothelial cells, as mimicked by eNOS transfection into hASMC, may activate generation of VEGF in sub-endothelial smooth muscle cells, leading to increased synthesis of VEGF protein necessary for turnover and restitution of endothelial cells.

Abstract
The aim of this study was to optimize the conditions for in vitro lipotransfection of rat vascular smooth muscle cells (VSMC) with bacterial beta-galactosidase gene and bovine endothelial nitric oxide synthase (ecNOS) gene. Transfection efficiency of four liposomes: Transfectam, Lipofectin, Unifectin-10, and Maxifectin was compared. The best results (efficiency 1-5%) were obtained with Maxifectin, when transfections were performed in VSMC cultures being at 50% confluency, with 1 microg DNA and 10 microl liposome per well, and when the liposome/DNA complexes were coincubated with the cells for 24 h. This method allowed detection of the transgene activity 12 h after the beginning of the transfection, with maximum values between the second and fourth days. The expression of the potentially therapeutic ecNOS gene was evidenced by confirmation of ecNOS mRNA generation, indirect detection of active ecNOS protein and by measurement of nitrite ion accumulation in the medium from the transfected cell cultures.

Abstract
The regulation of vascular wall homeostasis by nitric oxide (NO) generated by endothelium is being intensively studied. In the present paper, the involvement of NO in the vascular endothelial growth factor (VEGF), insulin or leptin-stimulated proliferation of human endothelial cells (HUVEC) was measured by [3H]thymidine or bromodeoxyuridine incorporation. VEGF and insulin, but not leptin, increased NO generation in HUVEC, as detected with ISO-NO electrode. Proliferation of HUVEC induced by leptin was not changed or was higher in the presence of N(omega)-nitro-L-arginine methyl ester (L-NAME) a nitric oxide synthase (NOS) inhibitor. In contrast, L-NAME blunted the proproliferative effect of VEGF and insulin. Furthermore, we demonstrated that, in human arterial smooth muscle cells (hASMC) transfected with endothelial NOS (eNOS) gene, the generation of biologically active VEGF protein was NO-dependent. Inhibition of NO generation by L-NAME decreased the synthesis of VEGF protein and attenuated HUVEC proliferation induced by conditioned media from transfected hASMC. Endothelium-derived NO seems to participate in VEGF and insulin, but not leptin, mitogenic activity. Additionally, the small amounts of NO released from endothelial cells, as mimicked by eNOS transfection into hASMC, may activate generation of VEGF in sub-endothelial smooth muscle cells, leading to increased synthesis of VEGF protein necessary for turnover and restitution of endothelial cells.

Abstract
Several studies have already demonstrated that oxidized- LDL decreases nitric oxide (NO) generation by cytokine-stimulated macrophages. However, the mechanisms of such an inhibition have not been yet elucidated. NO generation by inducible nitric oxide synthase (iNOS) is dependent on the presence of cofactors for NO generation, tetrathydrobiopterin (BH4) among them. The NO generation by these cells is also regulated by some endogenous inhibitors, like TGF-beta. Therefore, the aim of our recent study was to investigate the influence of ox-LDL on the expression of iNOS and GTP cyclohydrolase I (GTP-CH I), the key enzyme involved in the BH4 synthesis as well as the ox-LDL effect on TGF-beta expression in rat macrophages stimulated with IFNgamma (250 U/ml) and LPS (500 ng/ml). Macrophages, activated in this way, express iNOS, GTP-CH I, and TGF-beta mRNA. This expression was inhibited when the macrophages were preincubated for 24 hours with ox-LDL (100 microg/ml). Quantitative PCR revealed about 10-fold inhibition of iNOS gene expression by ox-LDL. As a consequence of down-regulation of iNOS and GTP-CH I genes, almost 3-fold diminished generation of NO2- by rat macrophages was observed. An inhibition of the TGFbeta mRNA expression was also found. Our studies indicate that decreased NO generation by ox-LDL treated macrophages may be the result of the diminished expression of both iNOS and GTP-CH I genes. This effect may be mediated by the activity of certain endogenous inhibitors of gene expression, however, our studies exclude the TGF-beta as a candidate for this activity.

Abstract
In this work we discussed selected questions about the Helicobacter pylori pathogenesis linked with the components of cell-walls as well as with toxins and enzymes externally secreted by this bacteria. We also paid attention to some theories which try to imperf the damaging effects of the bacteria on the mucosa of the upper part of the alimentary canal, specifically underlining the possible link between the Helicobacter pylori infection and the increase of the concentration of cytotoxically acting nitric oxide (NO).

Abstract
The fact that an increased blood insulin level is observed in patients with coronary artery disease (CAD) confirms the hypothesis that insulin promotes the development of atherosclerosis. The low high-density lipoprotein (HDL) concentration observed in such patients may contribute to alteration in reverse cholesterol transport and promote the accumulation of sterols in vascular tissue. We examined the effect of insulin (20-1000 microU mL-1) on cholesterol efflux into HDL3 particles from human blood monocyte/macrophages and rat peritoneal macrophages preloaded with labelled cholesterol esters, and the influence of insulin on the accumulation of sterols by rat liver cells and HepG2 cell line in vitro models. Insulin at concentrations up to 250 microU mL-1 inhibited the efflux of cholesterol from rat macrophages and promoted high uptake of sterols by both types of hepatic cells. Pharmacological concentrations higher than 250 microU mL-1 exerted the opposite effect. In the case of human macrophages, an insulin concentration of 20 microU mL-1 increased cholesterol removal, whereas 100-200 microU mL-1 insulin inhibited cholesterol removal from cells, and very high concentrations (> 350 microU mL-1) again increased cholesterol removal. We have shown that insulin excess counteracts the beneficial effects of HDL in removing cellular cholesterol and, therefore, may promote development of atherogenesis.

Abstract
We compared the high-density lipoprotein (HDL) composition and particle heterogeneity in 60 nonobese (normal body mass index, BMI) men suffering from coronary artery disease (CAD) with normolipemia and normoinsulinemia with lower and higher insulin output during the oral glucose tolerance test (silent hyperinsulinemia). The apolipoprotein apoAI, apoAII, and apoE levels were higher in the high insulin response (HI) group than in low insulin response (LI) group. The ratio of apoAI versus total protein and the ratio of apoAI versus total cholesterol were increased in HI compared with LI. The lipid components in HDL were higher in LI than in HI, while for HDL2 they were higher in HI. The fractioning of HDL by gradient gel electrophoresis revealed a different pattern of HDL particles in both groups. The larger particles, HDL2b and HDL2a (mean particle diameters 10.6 and 9.2 nm, respectively), occur more frequently in HI patients (up to 60%) than in LI patients, whereas the smaller particles, HDL3a and HDL3b (mean particle diameters 8.6 and 7.8 nm, respectively), predominate in LI patients. Our results demonstrate that even in the normoglycemic, normocholesterolemic CAD patients, a high insulin output observed during the oral glucose tolerance test may be connected with a different HDL particle pattern, which suggests changes in the reverse cholesterol transport.

Abstract
Effects of NO-donors (3-morpholinosydnonimine-SIN-1 and sodium nitroprusside NaNP) on the accumulation and degradation of oxidized LDL (ox-LDL) by macrophages were studied. Ox-LDL, but not native-LDL (n-LDL) suppressed the LPS-stimulated biosynthesis of NO by macrophages. SIN-1 at low concentrations < 100 microM was without any effect while SIN-1 at high concentration (300 microM) and NaNP (30-300 microM) stimulated the accumulation and degradation of ox-LDL by macrophages. The pretreatment of macrophages with NG-monomethyl-L-arginine (L-NMMA, 3 microM) for 24 hours had the same stimulatory effect. The inhibition of endogenous formation of NO, by L-NMMA profoundly changed the pattern of action of NO-donors on ox-LDL catabolism by macrophages; the stimulatory action of SIN-1 was transformed to the inhibitory action on the accumulation and degradation of ox-LDL whereas NaNP lost its stimulatory action entirely. Our interpretation of this unexpected interactions between SIN-1, NaNP and L-NMMA is as follows. Endogenous NO in macrophages inhibits the accumulation of ox-LDL and therefore, the stimulatory effect of L-NMMA has been overcome by exogenous NO from SIN-1. However, NO at high concentrations promotes lipid accumulation in macrophages and thereby, in the absence of L-NMMA, SIN-1 at high concentrations and NaNP produced a paradoxical stimulatory effect in macrophages. NaNP is not a proper NO-donor and its mode of action differed from that of SIN-1. In conclusion, NO at low physiological concentrations keeps scavenger receptors of macrophages downregulated and hence endogenous NO may show anti-atherogenic properties.

Abstract
The effect of nitric oxide donor--sodium nitroprusside (NaNP) and PGE2 on the LDL-receptor activity and LDL cellular accumulation by isolated human blood lymphocytes was investigated. Preincubation of lymphocytes with lipoprotein deficient medium (LPDS) resulted in the increase of the LDL-receptor activity and the LDL-cellular accumulation. NaNP (30-300 microM) dose-dependently prevented the increase of the LDL-receptor activity as well as the accumulation of LDL by lymphocytes. However, in "starwing" cells (cells with high LDL-receptor activity) the effect of NaNP on the receptor activity was biphasic. At concentration up to 100 microM NaNP inhibited, while at a concentration of 300 microM, it activated the LDL-receptor activity. PGE2 (3-30 microM) inhibited LDL catabolism, however, this effect was hardly concentration-dependent.

Abstract
Inversive association between concentration of plasma high density lipoprotein (HDL) components and endogenous insulin response to oral glucose uptake was observed in 89 healthy, normolipidaemic, non obese, non diabetic male subjects. Inversive correlation between sum of insulin released during oral glucose tolerance test and HDL free and esterified cholesterol as well as apolipoprotein A1 concentration were confirmed. Coexistence of increased insulin secretion and low ratio of free cholesterol concentration to esterified cholesterol and to proteins in HDL was also observed. In separate group of subjects with normal glucose tolerance in high insulin response subgroup the cholesterol (free and esterified) and protein concentrations were lower than in subgroup with low insulin response. The free cholesterol/esterified cholesterol and free cholesterol/protein (apoA1) ratios were decreased in high insulin response subgroup. It is concluded that low concentration of free cholesterol is a most significant change of HDL composition in hyperinsulinemic, healthy men.
