Abstract
OBJECTIVES The aim of the following study was to assess antisperm antibodies in sera samples of infertile men and women, as well as from prepubertal boys by means of flow cytometry. MATERIAL AND METHODS We tested sera samples of infertile and fertile adult populations, prepubertal boys with gonadal disorders and healthy prepubertal boys. The indirect immunobead test and flow cytometry were used to detect antisperm antibodies. RESULTS The comparison of antisperm antibody levels in sera samples of adult infertile versus healthy controls (men and women) evaluated by means of flow cytometry did not reveal statistically significant differences. The only significant correlation found were results obtained by IDIBT and FCM for IgG antisperm antibodies for infertile adult group (r = 0.507, p = 0.012). The comparison of antisperm antibody levels in sera samples from prepubertal boys revealed statistically significant differences for all tested antibody isotypes. Diagnostic values compared for both assays showed markedly better discriminatory ability of flow cytometry for analyzed groups of prepubertal boys than for adult populations. CONCLUSIONS Flow cytometry test may be used to verify antisperm antibody levels in prepubertal boys with testicular failures.

Abstract
This aim of the study was to investigate whether human leukocyte antigen (HLA)-DQA1*0505 sharing or the maternal killer immunoglobulin-like receptor (KIR) repertoire is associated with recurrent spontaneous abortion (RSA) or repeated implantation failure (RIF). The study included 224 couples with RSA, 61 couples with RIF, 182 fertile couples, and 10 couples with successful in vitro fertilization and embryo transfer (IVF)/ET at first cycle. HLA-DQA1*0505 typing using polymerase chain reaction-sequence-specific oligonucleotide (PCR-SSO) was performed in 185 RSA (117 with alloimmune abnormalities and 68 of autoimmune etiology), 61 RIF and 182 control couples, and KIR genotyping using polymerase chain reaction-sequence-specific primer (PCR-SSP) in 167 RSA and 55 RIF cases as well as 46 RSA and 10 IVF controls. No differences in DQA1*0505 sharing were found between patients and controls. In RSA and RIF women, the ratio of inhibitory to activating KIRs was slightly lower (1.53 and 1.85 vs 2.03 in controls). The analysis of maternal inhKIR and fetal HLA-C molecule pairs showed that the 'less inhibiting' combination KIR2DL3-C1 was found in higher percentage in subfertile (mainly RIF) than in fertile couples. In contrast, the percentage of cases possessing the 'strong inhibiting' combination KIR2DL1-C2 was lower in the RSA and RIF groups in comparison with that in the control groups (17.36% vs 23.91 and 16.36% vs 40%, respectively). In women with >or= 6 implantation failures, the KIR2DL1-C2 combination was not found in any of them (P = 0.0014), and the KIR2DL3-C1 combination was not found in the control IVF group. The results oppose the suggestion that increased HLA-DQA1*0505 sharing predispose to RSA or RIF. The KIR2DL3-C1 combination (or lack of the KIR2DL1-C2 one) is associated with implantation failure.

Abstract
In 2006 were reported first results on induction of pluripotential stem cells from adult somatic cells. It was successfully performed transfection by using genetic engineering and the effective overexpression of four transcription factors, OCT4, SOX2, c-MYC, KLF4 has been obtained. Thus pluripotency was induced in finally differentiated mammalian somatic cells with comparable to embryonic stem cells morphological and transcriptomic profiles. Before, it was only possible by using cloning procedure with diploid nucleus transfer to enucleated oocyte. Soon after range of reports appeared describing genetic modifications of variety human somatic cells enabling them pluripotency. The aim of this article was to summarise a present knowledge with several listed goals to be achieved before the first clinical trials with induced pluripotent stem cells can be feasible. Aspects of cardiovascular diseases treatment have been outlined.

Abstract
The presence of antisperm antibodies in male individuals before puberty is controversial due to the lack of finally differentiated male germ cells. It was questioned whether the pathologic conditions of the male gonad may influence antisperm antibody formation in individuals before puberty. Sera samples of 76 individuals and 10 healthy boys with testicular failure (mainly uni- or bilateral cryptorchidism) were examined by means of indirect immunobead-binding test (IDIBT). The presence of antisperm antibodies was found in 3.95% of the studied subjects. Antibodies recognizing antigenic determinants present on the surface of mature sperm cells may be produced before puberty in individuals suffering from cryptorchidism or the other gonadal disorders. Antisperm antibodies that did develop in a minority of the studied male population may be proof for individual predispositions to autoimmune reactions.

Abstract
Satellite cells are committed precursor cells residing in the skeletal muscle. These cells provide an almost unlimited regeneration potential to the muscle, contrary to the heart, which, although proved to contain cardiac stem cells, possesses a very limited ability for self-renewal. The idea that myoblasts (satellite cell progenies) may repopulate postinfarction scar occurred around the mid-1990s. Encouraging results of preclinical studies triggered extensive research, which led to the onset of clinical trials. These trials have shown that autologous skeletal myoblast transplantation to cure heart failure is feasible and relatively safe (observed incidences of arrhythmia). Because most of the initial studies on myoblast application into postischemic heart have been carried out as an adjunct to routine surgical procedures, the true clinical outcome of such therapy in regard to cell implantation is blurred and requires to be elucidated. The mechanism by which implantation of skeletal myoblast may improve heart function is not clear, especially in the light of inability of these cells to couple electromechanically with a host myocardium. Successful myoblast therapy depends on a number of factors, including: delivery to the target tissue, long-term survival, efficacious engraftment, differentiation into cardiomyocytes, and integration into the new, unique microenvironment. All these steps constitute a potential goal for cell manipulation aiming to improve the overall outcome of such therapy. Precise understanding of the mechanism by which cells improve cardiac function is essential in giving the sensible direction of further research.

Abstract
Stem cells are self-renewing multipotent progenitors with the broadest developmental potential in a given tissue at a given time. Normal stem cells in the adult organism are responsible for renewal and repair of aged or damaged tissue. Adult stem cells are present in virtually all tissues and during most stages of development. In this review, we introduce the reader to the basic information about the field. We describe selected stem cell isolation techniques and stem cell markers for various stem cell populations. These include makers for endothelial progenitor cells (CD146/MCAM/MUC18/S-endo-1, CD34, CD133/prominin, Tie-2, Flk1/KD/VEGFR2), hematopoietic stem cells (CD34, CD117/c-Kit, Sca1), mesenchymal stem cells (CD146/MCAM/MUC18/S-endo-1, STRO-1, Thy-1), neural stem cells (CD133/prominin, nestin, NCAM), mammary stem cells (CD24, CD29, Sca1), and intestinal stem cells (NCAM, CD34, Thy-1, CD117/c-Kit, Flt-3). Separate section provides a concise summary of recent clinical trials involving stem cells directed towards improvement of a damaged myocardium. In the last part of the review, we reflect on the field and on future developments.

Abstract
Evidence has been accumulating that individual chromosomes in human sperm cells occupy defined, non-random positions. Our earlier study suggested that abnormal spermatogenesis in carriers of reciprocal translocations was reflected in the changes in the intranuclear topology of sperm chromosomes. The purpose of this study was to determine whether the increased level of disomy of sperm chromosomes may be the factor that can disturb topology within the sperm nuclei. The results obtained indicated that within the sperm nuclei of fertile individuals the centromeres of chromosomes 15, 18, X and Y were localized in a small area that may be a fragment of the chromocentre. When compared with the intranuclear positions of the same chromosomes in sperm nuclei of infertile patients with an increased level of aneuploidy, some disturbances in the centromere area were found. In disomic sperm cells (n + 1) centromeres 15,15 or 18,18 or YY (but not X,X) had a shifted average longitudinal position in comparison with normal sperm cells (n = 23).

Abstract
cAMP responsive element modulator (CREM) activator isoforms are involved in mammalian spermatogenesis and spermiogenesis. CREM proteins are highly expressed in postmeiotic germ cells of rodents and primates. Homozygous CREM inactivated mice exhibit round spermatid maturation arrest. The lack of CREM expression at both the mRNA and protein levels is associated with spermatid maturation arrest in infertile patients. Using real-time RT-PCR, we have examined the levels of CREM activator isoform mRNAs: CREMtheta1, CREMtheta2 and CREMt2 + Ex-gamma in gametogenic and interstitial cell fractions from normal human testis, in homogenized tissue samples from spermatogenic arrest and from testicular tumors. We have shown for the first time the presence of CREM activator isoform containing exon gamma (CREMtau2 + Exgamma) in normal human spermatogenesis. Among the three CREM isoforms, CREMtheta1 was expressed in its highest level in the male gonads. In comparison, CREMtheta2 mRNA was significantly less suggesting that the P3 promoter is much more active in human testis than the P4 promoter. Minimal-nill levels of mRNA for either of the CREM activator isoforms were detected in lymphocytes or in gonadal tissues from patients with SCOS (Sertoli Cell Only Syndrome). This data underlines the significance of CREMtheta1 isoform in the regulation of transcription during post-meiotic germ cell differentiation.

Abstract
Human hybridoma cell lines are often unstable and loose ability for antibody production. Sometimes, they show low and varying levels of heavy and light chains synthesis. Therefore it is reasonable to preserve generated specificities of light and heavy chains by cloning them to phagemid vector and creating phage display library. The aim of this study was to construct phage display library of Fab fragments recognizing sperm surface antigens. The source of mRNA constituted seven hybridoma cell lines producing antisperm antibodies which was proved by ELISA, and agglutination test as well as by inhibition of sperm to penetrate hamster oocytes. Fragments of cDNA encoding kappa/lambda and gamma chains were cloned into pComb3HSS phagemid vector and amplified in XL-1Blue. The library was panned against whole unfixed sperm cells. Three positive clones selected after fourth round of panning showed heavy chain belonging to VH4 family, two of them (G28, K61) possessed lambda chain from VL2 family and one (H43) kappa chain from VK1 family. As these Fabs revealed similarities to antibodies against some proteins involved in sperm motility and cell fusion it can be suggested that these Fabs may be a cause of infertility. Finally, we proved that it is feasible to preserve specificities produced by human hybridomas using phage display technique and we recovered some Fabs which may be of diagnostic and research value, and may also have some value for contraceptive vaccine.

Abstract
Recently it has been shown that the nucleus of the human spermatozoon appears to possess a specific architecture. The current prevailing view is that spatial organization of the male genome contains information critical for the spermatozoon's function as well as for early embryonic development. The purpose of this study was to determine whether there are alterations in intranuclear localization of centromeres in spermatozoa of chromosomes associated with particular reciprocal chromosome translocations (RCT). We analyzed the longitudinal and spatial localization of centromeres of selected chromosomes in sperm nuclei of four control males with normal karyotypes as well as in six carriers of reciprocal chromosome translocations: t(1;7), t(7;2), t(7;13), t(7;9), t(9;14), and t(4;13). Our study revealed that chromosomes with translocations may have shifted their intranuclear localization and that these translocations may influence the localization of other chromosomes in sperm nuclei. The chromocenter in sperm nuclei of translocation carriers was widened toward the apical side in comparison with chromocenter sites visible in control males. Our study also revealed interindividual differences in the localization of the Y chromosome centromere in the chromocenter area of sperm from fertile individuals.

Abstract
We have examined the effect of white blood cells (WBCs), various proinflammatory cytokines, or a combination of the two on the peroxidation of human sperm membrane lipids in in vitro conditions. Six recombinant cytokines, such as interleukin-1beta (IL-1beta), IL-6, IL-8, IL-12, IL-18, and tumor necrosis factor alpha (TNF-alpha), used singly or in combinations, were analyzed. WBCs were isolated from the whole heparinized blood using a density gradient technique (Histopaque 1.077). Spermatozoa were isolated from semen samples with normal sperm parameters by both the swim-up technique (swim-up fraction) and by a discontinuous Percoll gradient centrifugation (90% and 47% Percoll fractions). Peroxidative damage to sperm membrane lipids was assessed by determining the concentration of malondialdehyde (MDA) in lysates of spermatozoa using high-performance liquid chromatography (HPLC). There were no statistically significant differences in MDA concentrations between sperm fractions incubated with cytokines and respective controls (spermatozoa alone). In spermatozoa isolated by the swim-up technique, the MDA level was significantly higher only after incubation with IL-6 and IL-8 plus WBCs when compared to sperm incubated with leukocytes alone (0.62 +/- 0.21 micromol/L and 0.42 +/- 0.22 micromol/L, respectively; P < .05). In spermatozoa recovered from the 47% Percoll, only a combination of IL-12 and IL-18 used together with WBCs was linked with a significant increase in MDA concentration (from 0.41 +/- 0.13 micromol/L to 0.65 +/- 0.19 micromol/L; P < .05). The results obtained suggest that cytokines produced during the inflammatory process intensify the level of oxidative stress caused by leukocytes, which may have serious consequences for sperm membrane integrity.

Abstract
OBJECTIVE To assess the in vitro effect of five bacterial strains isolated from semen samples (Escherichia coli, Staphylococcus haemolyticus, Streptococcus oralis, Bacteroides ureolyticus, and Ureaplasma urealyticum) on reactive oxygen intermediate (ROI) release and lipid sperm membrane peroxidation in the coincubated suspensions of white blood cells (WBC) with spermatozoa. DESIGN An in vitro model of semen infection. SETTING Basic research laboratory. PATIENT(S) Healthy normozoospermic volunteers and healthy blood donors. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Chemiluminescent assay was used to evaluate ROI generation by WBC. Malondialdehyde (MDA) concentration was determined in sperm lysates using high-performance liquid chromatography. RESULT(S) Of the bacterial strains tested, B. ureolyticus, S. haemolyticus, and E. coli caused the greatest damage to sperm membrane lipids. An increase in MDA levels in sperm lysates was a natural consequence of bacteria-induced ROI generation. The WBC usually enhanced harmful activity of the infectious agent toward the cell membranes. CONCLUSION(S) The harmful effect of bacteria on spermatozoa depends on the type and species of microorganisms invading, colonizing, or infecting the male genital tract and is associated with the accompanying oxidative stress. The presence of leukocytes in semen appears to be the additional factor enhancing the sperm lipid membrane peroxidation, which may affect the fertility status.

Abstract
IL-18 is a pleiotropic cytokine involved in the regulation of both innate and adaptive immunity. It plays a key role in the autoimmune, inflammatory and infectious diseases. IL-18 acts via a receptor complex that closely resembles that of IL-1, consisting of a ligand binding protein, IL-18Ralpha, and an accessory protein, IL-18RAP (IL-18Rbeta). IL-18RAP is essential for IL-18 signal transduction and ligand binding affinity to IL-18Ralpha receptor chain. mRNA of gene coding for IL-18RAP in human testicular tissue and the nucleotide sequence of splice variants was carefully examined. We have found for the first time ever, IL-18RAP mRNA in studied tissue samples of physiological testis. Using the RT-PCR technique, the whole coding sequence of this gene was amplified. An alternative splicing of mRNA for IL-18RAP was then discovered and subsequently confirmed by cDNA sequencing. The putative amino acid content was predicted and a computer modeling was performed. It might be hypothesized that the truncated forms of IL-18RAP can be involved in the complex mechanism of IL-18 activity regulation.

Abstract
Although the immunogenic properties of sperm have been explored for a few decades, none of the antigens studied so far appears to be an effective target, to inhibit the fertilization process or shown the full spectrum of sperm antigenic potential. Antisperm antibodies (ASA) collected from infertile individuals and prepubertal boys with cryptorchidism together with two-dimensional (2D) electrophoresis have been employed. Immunoreactive antigens were cored from silver stained 2D gels and analyzed by mass spectrometry (MS). The obtained sequences were searched in the published protein databases. Altogether, 35 different sperm entities were identified in accessible protein databases, out of which 10 appeared to be sperm-specific. Additionally, 6 amino acid sequences indicated novel (hypothetical) proteins. Seventeen sperm entities were detected in sera samples from immune infertile males and 18 entities in ASA-positive seminal plasma (SP). Interestingly, we identified a few sperm structures, none of them sperm specific in sera samples from infertile females. Although, infertile males from whom the ASA-positive SP samples were obtained, did not have ASA in their circulation, the range of sperm antigens detected by systematic and local antibodies overlapped to a great extent (six identical entities). Sera samples from prepubertal boys allowed to show antigens, previously thought to be only present on mature sperm. Three out of four detected were sperm-specific. Using serum and SP of ASA-positive infertile adults and sera samples of prepubertal boys with testicular failure, we have extended the range of known, immunogenic sperm proteins as well as identified some novel antigens (n=6) of human sperm for further characterization.

Abstract
Epidemiological studies regarding male infertility have revealed that more and more infertile men suffer from acute or chronic inflammation of the genitourinary tract, which often occurs without any symptoms. The inflammatory reactions within the male genital tract are inevitably connected with oxidative stress. Growing evidence indicates that imbalance between prooxidative and anti-oxidative substances in semen leads to metabolic and functional disorders of male germ cells and may be a primary cause of some types of infertility. The infectious factor and local tissue damage can lead to the infiltration of leukocytes to the inflammatory site. This is in an obvious way connected to the production and release of large amounts of reactive oxygen species (ROS), which trigger immune responses directed against the infectious agent, and the simultaneous secretion of numerous biological substances, thereby escalating the inflammation. Some of these factors are proteases and proinflammatory cytokines. Extended exposure of spermatozoa to ROS may lead to the peroxidation of sperm membrane lipids. Many studies point to the combined activities of inflammatory mediators in exerting toxic effects on spermatozoa. The local influences of biologically active substances released by activated leukocytes in the course of the inflammatory response and the mutual interactions of various factors (bacteria, leukocytes, proinflammatory cytokines) at the site represent a complex puzzle.

Abstract
Interleukin-1 (IL-1) is a pleiotropic cytokine that may play a role in contributing to the specific immune environment of mammalian testis and in regulating cell differentiation. We have determined the transcription activity of the IL-1 gene family (using real-time polymerase chain reaction (PCR)) in two main functional testicular compartments (interstitial and intratubular ones), and in tissue homogenates obtained from patients with fertility disorders (spermatogenic arrest and testicular tumors). We observed the prominent expression of gene coding for IL-1 receptor antagonist (IL-1RA) in a purified fraction of gametogenic cells (normal gonad). Caspase-1 (ICE - IL-1beta-converting enzyme) was highly expressed (on mRNA level) in interstitial compartments as well in testicular tumors (immune enhancement?). In addition we found, that the activity of IL-1RA gene decreased along spermatogenic alteration in an inversely related manner with IL-1alpha (from normal gonad through spermatogenic arrest to Sertoli cell only syndrome). Therefore, the quotient value of IL-1alpha/IL-1RA could potentially serve as the diagnostic molecular probe for spermatogenesis assessment. The precise level of mRNA for IL-1-IL-18 cytokines and their receptors, and specifically of the receptor antagonist in immune privileged gonad, could be one of the main factors responsible for maintaining testicular homeostasis, thus enabling generation of the mature spermatozoa.

Abstract
Although feasibility and safety of autologous stem cells administration to the post-infarction heart has been proven it is not known what proportion of cells effectively do home at the damaged site. Therefore, we have labeled autologous bone marrow cells (ABMC's) by radioactive Indium and single photon emission computed tomography (SPECT) tissue distribution has been analyzed. It was detected that up to 10% of the cells were retained within the myocardium while their majority migrated or has been anchored at the spleen and liver. Comparing the number of homed cells to the total number of cells delivered one may postulate the indirect role for few hundred thousands ABMC's at heart regeneration.

Abstract
Increasing experimental evidence indicates that skeletal myoblasts can be considered as a possible source of cells for regeneration of contractile performance in chronic postinfarction myocardial injury. In experimental models, the observed functional benefit of transplanting skeletal myoblasts into an area of chronic fibrotic myocardial scar has led to the development of clinical trials to evaluate the potential use of autologous skeletal myoblasts for myocardial regeneration in patients with postinfarction heart failure. We conducted an independent, phase I clinical trial to evaluate myoblast transplantation during coronary artery bypass grafting. In addition, to test whether the effect of transplanted cells on myocardial contractility was independent of revascularization, we performed a clinical study of percutaneous transvenous myoblast transplantation-the POZNAN trial. These trials have shown the feasibility of myoblast transplantation during cardiac surgery and via a percutaneous route, as well as the safety of both procedures when performed with concurrent prophylactic administration of amiodarone. Here, we review the details of our observations from both of these phase I clinical trials in the context of the clinical work in cardiovascular cell transplantation performed by others.

Abstract
Reciprocal chromosomal translocations (RCT) have long been recognized as important etiological factors in reproductive failure. In the present study, the meiotic segregation patterns of the spermatozoa of two related t(4;5)(p15.1;p12) carriers (proband and his father) were compared to the empirical data from a three-generation pedigree for risk assessment. Cytogenetic analysis of the metaphase chromosomes was performed, and triple color fluorescence in situ hybridization (FISH) was applied to the sperm heads. Similar patterns of meiotic segregation were observed for both carriers, despite the finding of teratozoospermia in the proband but not in his father. In addition, an increase of aneuploidy in chromosome 15 in the proband and aneuploidy of chromosomes X and Y in the father were observed. The high rate of miscarriages (6/10 pregnancies and 4/7 pregnancies after ascertainment correction) in this family could be explained by the genetically unbalanced karyotype and fertilization mediated by the unbalanced spermatozoa observed for both men at a frequency of more than 60%. The risk assessment for unfavorable pregnancy outcomes was predicted as 1.6% for unbalanced progeny at birth and about 30% for miscarriage. These figures may be used as guidelines for the genetic counseling of families with similar RCT.

Abstract
IFN-tau is a signaling protein secreted by the bovine conceptus during the peri-implantation period and responsible for pregnancy recognition. Its main role is the prevention of pulsatile release of luteolytic PGF2alpha, but it also exerts immunomodulatory activities characteristic for other type I interferons. The aim of the study was to examine the effect of IFN-tau on the proliferation and distribution of peripheral blood lymphocyte subsets during one-way mixed lymphocyte reaction (MLR) in cows and heifers. IFN-tau inhibited the proliferative response of lymphocytes in MLR both in cows and heifers in a dose-dependent manner, but cow lymphocytes were less susceptible than those ones from heifers. It was also showed that IFN-tau differentially changed lymphocyte subsets distribution in MLR in cows and heifers. In cows, the relative percentage of CD8(+) cells after MRL in the presence of IFN-tau was significantly lower than in heifers. Differential effect of rIFN-tau on proliferation and lymphocyte subsets distribution in a one-way MRL in cows and heifers indicated that the age of the mother is an important factor in immunomodulatory effect towards developing bovine embryo.

Abstract
BACKGROUND Nitric oxide (NO) generated by endothelial nitric oxide synthase (eNOS) plays a crucial role in vascular function and homeostasis. eNOS activity maintains normal vascular tone, regulates leukocyte-endothelial cell interactions, inhibits platelet aggregation, limits smooth muscle cell proliferation and influences cardiac myocyte contractility. The loss of endothelium-derived NO has been shown to result in serious cardiovascular abnormalities, which may indicate eNOS involvement in the origin/development of cardiovascular disorders. AIM Evaluation of eNOS mRNA level in the endothelium of human coronary arteries upon opioids treatment (mediators of ischaemic preconditioning) and after incubation with proinflammatory cytokines (stress stimuli). METHODS Different concentrations of beta-endorphin, endomorphin-1 and endomorphin-2 (alone or in combination with the opioid receptor blocker naloxone) as well as different concentrations of cytokines alone (IL-1beta, TNF-alpha) or in combination were applied to in vitro cultured human coronary artery endothelial cells (HCAEC). After 24 hrs incubation, the cells were harvested, mRNA extracted and relative quantification of eNOS mRNA was conducted using real-time PCR. RESULTS Opioid treatment altered eNOS expression; however, none of the changes reached a statistically significant level. As for proinflammatory cytokines, both TNF-alpha and IL-1beta substantially down-regulated the eNOS mRNA level (p <0.05). When applied in combination, these cytokines lowered eNOS mRNA even further (p <0.05). The effect was independent of the cytokine combination used. CONCLUSIONS It was demonstrated that proinflammatory cytokines exert a substantial and statistically significant negative effect on eNOS mRNA level in human coronary artery endothelial cells in in vitro culture. Unfortunately, we were unable to demonstrate significant changes within the eNOS mRNA pool upon opioid treatment. These results indicate that opioids (basal release) do not affect eNOS expression in normal in vitro culture conditions but might do so upon stress stimuli.

Abstract
We performed the segregation analysis of a relatively large pedigree of t(7;13)(q34;q13) carriers together with the sperm karyotype analysis of the one carrier using a tri-color fluorescence in situ hybridization (FISH) method. The risk assessments for unfavorable pregnancy outcomes in a series of 36 pregnancies in eight reciprocal chromosome translocation (RCT) couples of carriers were estimated directly from a pedigree after ascertainment correction. The individual probability rate for unbalanced child was predicted according to Stengel-Rutkowski and co-workers. The unbalanced karyotypes in the form of monosomy 7q34-->qter and trisomy 13q13-->qter were detected among stillborn/early death newborns with holoprosencephaly (HPE), cyclopia and other malformations. Based on clinical description of unkaryotyped stillbirth progeny, it can be assumed that the phenotype distinctions were connected with the unbalanced karyotype from 2:2 segregation (monosomy 7q with trisomy 13q) and 3:1 segregation as interchange trisomy 13 (Patau syndrome). Probability rates for miscarriages, stillbirth/early death were 12.9 +/- 6% (4/31) and 29 +/- 8.2% (9/31), respectively. The results of the meiotic segregation pattern indicated the rate of unbalanced spermatozoa for about 60%, with the unusual high rate (29.4%) of 3:1 segregant (i.e., 13.4% of the tertiary segregation and 16% of the interchange segregation). Adjacent-1 segregation followed with 23.5% and adjacent-2 followed with 7.2% of analyzed spermatozoa. The high rate of unbalanced gametes in comparison to the number of stillborn/early death and miscarriages detected in pedigree suggests a strong selection against unbalanced chromosomal constitutions during fetal development. It corresponds to a very small probability rate (about 0.3%) of viable unbalanced progeny from 3:1 meiotic segregation predicted for maternal carriers. This knowledge can be used in genetic counseling of families with similar RCT ascertained in a different way.

Abstract
Subacute cutaneous lupus erythematosus (SCLE) is a subset of lupus erythematosus that identifies patients with clinically recognized erythematous, nonscarring lesions, photosensitivity and serologic abnormalities. Anti-Ro (SS-A) antibodies are considered to be a typical immunopathologic marker of SCLE. Autoimmune diseases have been also characterized by the disturbances in the cytokine network. The aim of this study was to compare the concentrations of proinflammatory cytokines (IL-1beta, IL-6, IL-12, IL-18 and TNF-alpha) in serum of ANA-positive (antibody against nuclear antigen) and ANA-negative patients with SCLE. Sera samples were collected from 15 patients with SCLE (9 ANA-positive and 6 ANA-negative ones). The preliminary identification of autoantibodies as well as their titers was determined on HEp-2 cells using IIF method. Western blotting (EUROIMMUN) was applied to verify the results of IIF. Proinflammatory cytokine concentrations in the patients' sera samples were determined by enzyme-linked immunosorbent assay (ELISA) (Bender MedSystems). The levels of IL-12 were higher in ANA-positive patients than in ANA-negative subgroups [median (interquartile range), 330 pg/ml (128-708 pg/ml) versus 39.4 pg/ml (31.25-80 pg/ml)]. Similar differences were observed in the level of IL-18 [median (interquartile range), 508.4 pg/ml (180-1222 pg/ml) versus 100.5 pg/ml (78.1-154 pg/ml)]. The differences in TNF-alpha levels between the groups of ANA-positive and ANA-negative patients were at the verge of statistical significance, p<0.05. The sera levels of IL-1beta and IL-6 were low and of no significant difference concerning the ANA-positive and ANA-negative subgroups. Since serum levels of IL-12 and IL-18 were higher in ANA-positive patients than in ANA-negative patients, these cytokines might play an important role in the inflammatory process in SCLE.

Abstract
The article provides a summary of the present knowledge on the organization and chromatin structure in the nucleus of the human sperm cell. The study also presents views and hypotheses on the defined, non-random localization of chromosomes in the sperm nucleus. The individual chromosome territories constitute the central element of the intranuclear architecture. Within these territories, the chromosomes take on the configuration of "hairpin" extendines, with their centromeres towards the interior of the sperm nucleus and the telomeres directed towards the periphery. The functional purpose of this specific topology remains to be explained.

Abstract
The interphase cell nucleus is a highly compartmentalized structure in which chromosomes are located in separate, defined places called chromosome territories (CTs). Chromosome territories with interchromatin compartments (ICs) and the nuclear matrix determine the nuclear architecture. There is a connection between nuclear architecture and genome function. The topology of the chromosomes in the nuclei of somatic cells is summarized here. It is known that the size and location of chromosome territories are tissue specific and depend on the cell cycle and the size of the chromosomes and the density of the genes which are actively transcribed. The correlation between transcriptional activity, the level of chromatin structure, and the location of the chromatin domains is outlined. The tendency of the heterochromatin regions and the telomeres to associate and the influence of this on the nuclear architecture is highlighted. Some studies are focused on the indirect role of the elements of the nuclear matrix and the inner-nuclear membrane in maintaining the correct locations of chromosome territories. The role of interchromatin granule clusters (IGCs), which are located in the nuclear matrix and which remain active in nuclear processes connected with chromosome topology, is further described. The influence of cell differentiation on chromosome location is pointed out. The topology of chromosomes in evolutionarily distinct species is also mentioned in this review. The reciprocal location of the chromosome territories is probably one of the important epigenetical factors influencing correct genome function. The high level of the organization of chromatin and chromatin modifications create the unique epigenetic pattern of a particular cell type. This seems to indicate a critical role of the spatial genomic organization in regulating gene expression.

Abstract
A proportion of fertilized oocytes during classical in vitro fertilization (IVF) procedure was analysed depending on the following factors: number of mature oocytes, seminological criteria such as sperm morphology in raw semen and after its selection in a density gradient (six structural defects of a male gamete were taken into consideration), sperm concentration, motility parameters according to World Health Organization criteria and the functional tests: hypo-osmotic swelling assay and acrosomal reaction induced by calcium ionophore. Evaluation of DNA content in sperm by image cytometry and determination of malonyldialdehydes in seminal plasma were also performed. Seventy-nine semen samples from patients undergoing IVF were assessed. Apart from significant correlations obtained for selected semen parameters and proportion of fertilized eggs, logistic regression analysis showed that the best predictive factors for oocyte fertilization were normal morphology of sperm before and after gradient selection, grade B and C of sperm movement in raw semen, and DNA content after density gradient centrifugation, which all accounted for 76.7% of fertilization predictive value.

Abstract
We have analyzed two infertile male cohorts with (n=39) and without genital tract infection (n=14) comparing their selected seminological parameters with healthy controls (n=30). Genital tract infection (GTI) has been defined by the presence of leukocytes and pathological bacterial strains identified with Bio-Merieux tests. We have found statistically significant deteriorated semen volume, sperm concentration, motility, morphology and vitality in ejaculated samples of patients with genital tract infection in comparison to healthy controls. Statistically significant negative influence towards sperm reproductive potential has been revealed in case of Escherichia coli, Ureaplasma urealyticum and Staphylococcus aureus.

Abstract
A body of data exists on reactive oxygen species (ROS) release, however, no direct correlation was found between the oxidative stress and infertility. The aim of the study was to measure semen oxidative stress and its correlation with classical in vitro fertilization (IVF) rate. A prospective study in academic non-profit institution where 79 infertile couples were subjected to IVF programme was conducted. Two infertile groups were discriminated according to the pronuclei presence in IVF. The main outcome measure (pronuclei presence) was then correlated with lipid peroxidation product in semen (ROS effect). Although the average IL-8 levels and malondialdehyde (MDA) content in semen did not differ between the studied subgroups (successful vs. non-successful fertilization), a statistically significant negative correlation was found between MDA level and fertilization rate in performed regression analysis. Thus we may suggest that MDA levels in seminal plasma may have prognostic value for IVF success.

Abstract
A range of compounds with a role in oxidative stress were measured in ejaculates from 40 normozoospermic individuals and 93 infertile males. Ejaculates were classified according to WHO criteria. Seminal plasma and the sperm cell fraction were assessed separately for superoxide dismutase (SOD), catalase, xanthine oxidase, capability for singlet oxygen trapping and content of thiobarbituric acid-reactive substances (TBARS). Pathological cases defined as oligozoospermia, asthenozoospermia, or teratozoospermia revealed different backgrounds of oxidative stress as reflected by different levels of tested substances in every type of sperm pathology. In the majority of abnormal ejaculates, a significant increase in intracellular activity of SOD, decreased intracellular levels of catalase, elevated levels of xanthine oxidase and TBARS, and severely impaired singlet oxygen trapping were observed when compared to normozoospermic ejaculates. Interrelationships between SOD and TBARS, and between xanthine oxidase and catalase, appeared to be of key importance when analysed separately in seminal plasma and in spermatozoa or in a combination of both. Elevated xanthine oxidase levels and low capacity for singlet oxygen trapping are statistically significant factors for the evaluation of male infertility which can develop as a result of persistent oxidative stress.

Abstract
OBJECTIVE To evaluate cytokine levels (IL-1beta, TNF-alpha, IL-6, IL-8), soluble intercellular adhesion molecule-1 (sICAM-1) and number of macrophages in peritoneal fluid (PF) of women with no minimal endometriosis and associated (or not) infertility in order to discriminate between infertility and/or endometriosis. STUDY DESIGN Cytokines and sICAM-1 were measured by using quantitative enzyme-linked immunosorbent assay (ELISA) while the macrophages were identified by May-Grunwald-Giemsa and non-specific esterase staining and presented as medians. The measurements were performed in 78 women belonging to four selected subgroups according to their endometriosis and/or infertility status. Statistical analysis was performed using Kruskal-Wallis non-parametric ANOVA test. Additionally, discriminant function analyses were performed. RESULTS We have found the most elevated macrophage numbers in the groups of women with endometriosis. IL-1beta did not present any statistically significant values differentiating the analysed subgroups. IL-6 (110.0 pg/ml) and TNF-alpha exhibited the highest concentrations (statistically significant) in a group of fertile women with endometriosis. IL-8 clearly differentiated between the subgroups with infertility and sICAM-1 was statistically significantly elevated in the subgroups of infertile women. In the forward discriminant analysis, when subdividing the studied population according to its infertility status (we considered macrophages, IL-8 and IL-6 in order of probability values), we have found striking probability value of 92% for the correct classification into an infertile population. CONCLUSION Out of the range of the analysed factors we have found only the sICAM-1 to be singled out between the standard discriminant analysis and the forward one. However, this important flagging molecule might be of considerable value for discrimination between different types of pathology at the level of immune effector function. The increased levels of TNF-alpha and IL-6 signified a group of fertile women with endometriosis; however only IL-6 presented a discriminating value in multifunctional analysis of examined subgroups. The analysed range of factors had a greater tendency to discriminate between infertility status rather than endometriosis.

Abstract
AIMS Several experimental studies and the initial clinical experience have shown that autologous skeletal myoblast transplantation into the area of post-infarction left ventricular injury results in an increase in segmental contractile performance. This phase I clinical trial was designed to assess the feasibility and safety of autologous skeletal myoblast transplantation performed via a percutaneous trans-coronary-venous approach in patients with post-infarction left ventricular dysfunction. METHODS AND RESULTS Ten patients with heart failure and presence of an akinetic or a dyskinetic post-infarction injury with no viable myocardium were included in the study. Skeletal myoblasts were obtained from a biopsy specimen and grown in cell culture. Patients were treated with prophylactic amiodarone infusion before and during the procedure, except one patient. Skeletal myoblast transplantations were performed uneventfully in nine patients using the TransAccess catheter system under fluoroscopic and intravascular ultrasound guidance. In one patient, the procedure was not performed because of the inability of appropriate coronary sinus guiding wire positioning across venous valve. In five patients, the anterior interventricular vein and in four patients, the middle cardiac vein were used to access the myocardium. Two to four intramyocardial injections 1.5-4.5 cm deep were performed in each patient, delivering up to 100 million cells in 0.4-2.5 mL of saline. During 6 months follow-up, New York Heart Association class improved in all patients and ejection fraction increased 3-8% in six out of nine cases. CONCLUSION These data suggest the feasibility and procedural safety of myoblast transplantation performed via the trans-coronary-venous approach using the TransAccess catheter system.

Abstract
Spermatogenesis is a phenomenon where two main processes proliferation and apoptosis, meet. Slight changes in their activities could lead to different pathologies, such as fertility disorder (excessive apoptosis) or testicular cancer (overproliferation). The IL-1 gene family includes genes which play important roles in both these processes and consists of IL-1?, IL-1ss, IL-18, the IL-1 receptor antagonist (IL-1RA), two IL-1 receptors (IL-1RI, IL-1RII), the IL-18 receptor (IL-18R?), and the receptor-associated proteins - IL-1RAcP and IL-18Rss. Caspase-1 (ICE - interleukin-1 converting enzyme), directly connected with apoptosis and responsible for the cleavage of IL-1b and IL-18, is also a member of the IL-1 family. The system of the numerous IL-1 receptors and their signal transduction involving protein cascades provokes a range of gene expressions necessary for the initiation and maintenance of inflammatory reaction. In the testis, IL-1 is constitutively expressed, where it creates a unique microenvironment for diploid gametogenic cell conversion into specialized haploid spermatozoa. It may also be an element of the physiological protection from autoimmune attack by host testicular antigens and a part of immune privilege. This review is to summarize the knowledge of the local control of spermatogenesis and immunomodulation in the male gonad. As infertility is one of the main problems of industrialized countries, study of the pathophysiology of the male genital tract appears essential in future clinical practice.

Abstract
BACKGROUND The influence of the marker chromosome on reproductive failure is difficult to assess, especially in the case of low-rate mosaicism. The aim of our work was to examine the meiotic segregation of the marker chromosome der(20) in the sperm of a normal male whose wife had experienced three miscarriages, and therefore to determine whether there occurred a gametogenic tissue-specific mosaicism. MATERIAL/METHODS The proband was a phenotypically normal 35-year-old man, referred for pre-conceptional counseling after his wife had experienced three miscarriages. Chromosome cytogenetic analysis was performed on peripheral blood lymphocytes using routine protocols. Sperm chromosome complements were obtained after penetration of zona-free hamster oocytes. Dual-color FISH analysis was performed using directly labeled probes identifying X, Y, 9 and 20 chromosomes. RESULTS A small marker chromosome der(20) was identified in 4% of the proband's lymphocytes and 8.25% of his sperm, which indicated mosaicism among the gametogenic cells, in which the proportion of cells containing the der(20) marker may reach a minimum of approx. 16%. CONCLUSIONS In this case, we addressed a problem whether a revealed marker der(20) was the cause of reproductive failure or just a coincidental finding. In our view, each case of low-rate mosaicism of the marker chromosome should be individually assessed.

Abstract
Epidemiologic studies on male infertility suggest that many cases should be considered idiopathic infertility, that is an exact cause of the inability to induce conception cannot be identified. Recently it was found that the redox status within the male gamete or in the semen can be at least partly responsible for the etiology of infertility. Each living cell is capable of producing reactive oxygen species (ROS), such as superoxide anion, hydroxyl radical, singlet oxygen, or hydrogen peroxide. This process involves the male germ cells as well. A certain amount of free radicals generated in the respiratory chain is necessary for the normal function of sperm cells. In cases of overproduction of ROS, the antioxidant potential of sperm cells can be exhausted and oxidative stress may develop. Prolonged exposure of sperm cells to ROS may cause peroxidation of the cell membrane lipids, alter the structure of protein receptors, enzymes, and transporter proteins, and affect sperm DNA fragmentation. This review aims to summarize the current state of knowledge regarding the redox system in male sperm and the consequences of oxidative stress on semen quality and sperm cell function.

Abstract
We overview the current knowledge about the use of skeletal myoblasts in regeneration of infarcted myocardium. Myoblasts are attractive candidates for cell source for cardiomyoplasty in chronic postmyocardial injury as indicated by experimental and initial clinical experience. We also review the recent developments in skeletal myoblasts transplantation techniques with special attention to percutaneous transvenous approach to deliver therapeutic agents into myocardium from the lumen of coronary veins under intravascular guidance.

Abstract
BACKGROUND Experimental studies have shown that skeletal myoblast transplantation into an area of postinfarction left ventricular injury results in an increase of segmental contractile performance that could be related to transplanted myoblasts. Initial experience with autologous skeletal myoblast transplantation in patients with postinfarction myocardial injury has also been obtained. METHODS Patients who survived an acute myocardial infarction and were scheduled to undergo coronary artery bypass grafting were screened by means of dobutamine stress echocardiography and included into the study when no contractility changes within akinetic/dyskinetic segments were observed. Ten patients who gave informed consent were enrolled, and autologous myoblasts (satellite cells) were isolated from the skeletal muscle biopsy. Myoblast injections into the akinetic/dyskinetic area were performed after constriction of the anastomoses during the coronary artery bypass grafting procedure. RESULTS Myoblast transplantations were performed after 3 weeks of in vitro culture in all patients. One patient died of a recent infarction at day 7 postoperatively because of a recent infarction in a remote area of the left ventricle. The left ventricular ejection fraction increased from 25% to 40% (mean, 35.2%) before the procedure to 29% to 47% (mean, 42.0%) during the 4-month visit (P <.05), and the effect was maintained throughout 12 months of follow-up. Sustained ventricular tachycardia was observed in 2 patients in the early postoperative period and in the other 2 patients after 2 weeks of follow-up. Prophylactic amiodarone infusion was used in the remaining 8 patients and prevented sustained ventricular tachycardia episodes. CONCLUSIONS Autologous skeletal myoblast transplantation for the treatment of postinfarction heart failure is feasible. Our initial observations justify further research to validate this method in a clinical practice.
