The impact of response type on affordance and spatial compatibility effects in human and object interactions.

Everyday social interactions or goal-directed actions towards objects activate action plans appropriate to their affordances. The spatial compatibility of a stimulus and a response might interfere with the activation of these action plans. In the present study, we examined how framing of interactions affects the interplay between affordance and spatial compatibility effects towards humans and objects in two separate experiments.

Stage-specific expression of Toll-like receptors in the seminiferous epithelium of mouse testis.

Genes encoding Toll-like receptors (TLRs) are expressed by germ cells in the mouse testis. Nevertheless, the expression of TLRs by germ cells has only been demonstrated for TLR-3, TLR-9, and TLR-11. Furthermore, the expression of each TLR in relation to the stage of spermatogenesis remains uncertain.

Expression of Toll-Like Receptors in the Lung Tissue of Mouse Fetuses Generated by in vitro Embryo Culture and Embryo Transfer.

Mouse fetuses generated by in vitro embryo culture and embryo transfer exhibit impaired lung development, altered composition of pulmonary epithelial cells associated with downregulation of several genes involved in lung development and toll-like receptor (TLR) signaling pathway. The aims of the present study were to determine the expression of all TLRs and to examine if the expression of TLRs, along with genes involved in TLR signaling pathway, is altered in the lung tissue of mouse fetuses generated through embryo culture and embryo transfer. Two experimental (EGs) and one control (CG) group were included in the study.

Transfer of mouse blastocysts exposed to ambient oxygen levels can lead to impaired lung development and redox balance.

In vitro culture under atmospheric oxygen puts embryos under oxidative stress and impairs preimplantation development. However, to what extent this process alters the redox balance in the perinatal period remains largely unknown. The aim of the present study was to examine if the redox balance is altered in the lung tissue of fetuses generated through transfer of mouse embryos exposed to atmospheric oxygen at different stages of development and to determine if this has any effect on lung morphogenesis and gene expression.

Changes on the Pancreas in Experimental Diabetes and the Effect of Lycopene on These Changes: Pdx-1, Ngn-3, and Nestin Expressions.

The aim of the present study was to investigate changes occurring in the number of beta cells, as well as the expressions of Ngn-3, nestin and Pdx-1 of pancreatic progenitor cells in the pancreas of experimentally-induced adult diabetic rats and to determine the effect of orally-administered lycopene on these changes. Following the administration of 50 mg/kg streptozotocin to rats, four groups of animals were established: control + corn oil, control + lycopene, diabetic + corn oil and diabetic + lycopene. The animals in the control + lycopene and diabetic + lycopene groups received 4 mg/kg lycopene for a period of four weeks.

Relationship between IL28B gene rs8099917 polymorphism and SVR in Turkish patients with hepatitis C virus genotype 1.

Background And Objective: The hepatitis C virus (HCV) which infects 3% of the world's population is a global challenge. Recently, genome-wide association studies (GWAS) have identified that the IL28B gene rs8099917 polymorphism was associated with the response to the pegylated-interferon alpha/ribavirin (PegIFNα/RBV) combination therapy in patients infected with HCV genotype 1. IL28B gene rs8099917 polymorphism should be determined before beginning treatment of HCV-infected patients to predict an individual's response.

Relationship between programmed cell death-1 polymorphisms and clearance of hepatitis B virus.

Programmed cell death-1 (PD-1) plays a critical role in regulating T-cell function during hepatitis B virus (HBV) infection. This study investigated the relationship between the polymorphisms of PD-1 gene and the susceptibility to HBV infection. Single nucleotide polymorphisms (SNPs) in PD-1 gene at positions +7146 G>A (guanine to adenine substitution) and +7209 C>T (cytosine to thymine substitution) were analysed using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 220 subjects with chronic hepatitis B infection and 165 spontaneous clearance of HBV subjects.

Contribution of cells derived from the area pellucida to extraembryonic mesodermal cell lineages in heterospecific quail chick blastodermal chimeras.

The current study has two main objectives: first, to determine if cells derived from the area pellucida are able to populate extraembryonic membranes, and second, to determine if donor cells have the potential to differentiate to endothelial (EC) and hematopoietic cells (HC) in the yolk sac and allantois, the two extraembryonic membranes functioning as hematopoietic organs in the avian embryo. To this end, quail chick chimeras were constructed by transferring dissociated cells from the areae pellucidae of the stage X-XII (EG&K) quail embryo into the subgerminal cavity of the unincubated chick blastoderm. The distribution of quail cells in the allantois, yolk sac, amnion, and chorion of resulting putative chimeras was examined using quail cell-specific antibody against a perinuclear antigen (QCPN) after 6 days of incubation.

No association of pre-microRNA-146a rs2910164 polymorphism and risk of hepatocellular carcinoma development in Turkish population: a case-control study.

Aim: MicroRNAs (miRNAs) are an abundant class of small non-protein coding RNAs with posttranscriptional regulatory functions as tumor suppressors and oncogenes. Aberrant expression and structural alteration of miRNAs are considered to participate in tumorigenesis and cancer development. It has been suggested that the presence of single nucleotide polymorphisms in precursor miRNAs (pre-miRNAs) can alter miRNA processing, expression, and/or binding to target mRNA and represent another type of genetic variability that can contribute to the susceptibility of human cancers.

p53 codon 72 polymorphism is associated with susceptibility to hepatocellular carcinoma in the Turkish population: a case-control study.

The tumor suppressor p53 gene plays a crucial role in preventing carcinogenesis through its ability to induce cell cycle arrest and apoptosis following DNA damage and oncogene activation. A guanine (G)/cytosine (C) common single nucleotide polymorphism (SNP) at second position of codon 72 in exon 4 of p53 gene determines a arginine (Arg) to proline (Pro) (Arg72Pro) aminoacidic substitution within the proline-rich domain of p53 protein. Arg72 and Pro72 allele are different from a biochemical and biological point of view and many reports suggest that they can modulate individual cancer susceptibility.

Atherosclerosis and acetylsalicylic acid are independent risk factors for hemorrhage in patients with gastric or duodenal ulcer.

Objective: Risk factors for hemorrhage due to gastric and/or duodenal ulcer in patients diagnosed by upper gastrointestinal (GI) endoscopy were investigated in the present study.

Methods: Medical records of 350 patients (226 males, 124 females) diagnosed as duodenal or gastric ulcers by GI endoscopy in the gastroenterology clinic were scanned retrospectively. Upper GI hemorrhage was detected in 92 patients by upper endoscopic examination.

No association of NAD(P)H: quinone oxidoreductase 1 (NQO1) C609T polymorphism and risk of hepatocellular carcinoma development in Turkish subjects.

NAD(P)H:quinone oxidoreductase 1 (NQO1) is a cytosolic enzyme that catalyzes the two-electron reduction of numerous quinoid compounds into their less toxic form, thus NQO1 protecting cells against oxidative stress. The gene coding for NQO1 has a single nucleotide polymorphism (C-->T) at nucleotide position 609 (proline to serine substitution at position 187 in amino acid sequence (P187S)) (rs1800566) of the NQO1 cDNA which results in very low enzimatic activity, so it would be expected that individuals with the homologous NQO1 C609T polymorphism would have a susceptibility developing cancer. Previous studies of the association between functional NQO1 C609T polymorphism and several human cancers have had mixed findings but association of NQO1 C609T polymorphism with hepatocellular carcinoma (HCC) development has yet to be investigated.

Influence of CYP2C19 functional polymorphism on Helicobacter pylori eradication.

Background/aims: Proton pump inhibitors are mainly metabolized by cytochrome P450 2C19 in the liver. Recently, some studies have shown that the acid suppressing effect of proton pump inhibitors are influenced by a functional polymorphism of cytochrome P450 2C19. The aim of the present study was to investigate the effect of cytochrome P450 2C19 polymorphism on Helicobacter pylori eradication in patients who received proton pump inhibitors based triple therapy.
