Opis:
Pre-eclampsia, the most common pregnancy associated syndrome, is connected with remodelling of extracellular matrix of the umbilical cord tissues. Since the fibroblast growth factor (FGF) is known to be a stimulator of collagen and glycosaminoglycan biosynthesis, one may expect that it plays an important role in such a remodelling. Studies performed on the umbilical cords of 10 control and 10 pre-eclamptic newborns demonstrated that both the umbilical cord arterial wall and Wharton's jelly contain FGF mainly in complexes with the components of different molecular mass. Pre-eclampsia is associated with a decrease of endogenous FGF-binding by soluble high molecular mass components of the umbilical cord. It is suggested that FGF released from these complexes may be actively bound by fibroblasts of the umbilical cord, stimulating them to produce collagen and sulphated glycosaminoglycans.

Introduction and objective. Vitamin D deficiency is common in obesity; however, its contribution in the development of metabolic complications remains uncertain. The aim of the study was to examine the relationships between vitamin D status and metabolic complications. Materials and method. The results of blood pressure measurements, biochemical tests and ultrasound of the liver were compared in both groups. The study was conducted at the Children’s University Hospital in Krakow, Poland. 30 obese adolescents (mean 13.23y.o.); 18 with 25OHD levels <20ng/mL, 12 with 25OHD>20 ng/mL. Results. The vitamin D deficient group presented with significantly higher values of the diastolic blood pressure (125.9vs.115mmHg), uric acid level (384.7vs.301.5umol/L) and lower phosphorus level (1.4vs.1.65mmol/L), higher prevalence of arterial hypertension (44vs.8.3%), and liver steatosis (25vs.8.3%); lower, but not significantly, levels of fibroblast growth factor 23 and fibroblast growth factor 19. Conclusions. Hypovitaminosis D in obese adolescents is associated with higher prevalence of arterial hypertension, liver steatosis, elevated serum uric acid and low phosphorus levels. The potential contribution of the fibroblast growth factor 23 and fibroblast growth factor 19 in these complications development needs further investigation.

Opis:
Bronchial asthma is characterized by persistent airway inflammation and airway wall remodeling. Among many different cells and growth factors triggering changes in bronchi structure, transforming growth factor β1-induced fibroblast to myofibroblast transition is believed to be very important. The aim of this study was to evaluate whether theophylline (used in asthma therapy) and two other methylxanthines (pentoxifylline and its active metabolite lisofylline), may affect transforming growth factor β1-induced fibroblast to myofibroblast transition in bronchial fibroblasts derived from asthmatic patients. We show here for the first time that selected methylxanthines effectively reduce transforming growth factor β1-induced myofibroblast formation in asthmatic bronchial fibroblast populations. PTX was found to be the most effective methylxanthine. The number of differentiated myofibroblasts after PTX, LSF and THEO administration was reduced at least twofold. Studies on the use of methylxanthines opens a new perspective in the development of novel strategies in asthma therapy through their two-pronged, anti-inflammatory and anti-fibrotic action. In the future they can be considered as promising anti-fibrotic drugs.

Opis:
Our earlier paper has reported that Wharton's jelly is a reservoir of several peptide growth factors, including acidic and basic fibroblast growth factors (aFGF and bFGF, respectively). Both can be extracted by buffered salts solutions in the form of high molecular mass complexes, probably with a component(s) of the extracellular matrix. Both aFGF and bFGF from such extracts hardly penetrate 10% polyacrylamide gels during electrophoresis. Pre-treatment of Wharton's jelly with hyaluronidase slightly increased the extractability of aFGF, but did not affect the extractability of bFGF. In contrast, the pre-treatment of tissue homogenate with bacterial collagenase (2000 U/ml, 37°C, 18 h) increased the extractability of bFGF. The presence of β-mercaptoethanol in the extracting solutions increased the extractability of both FGFs, but did not release FGFs in their free form, despite reducing the molecular mass of the FGF-containing complexes. We conclude that both aFGF and bFGF are bound through disulphide bonds to a protein component of Wharton's jelly. We propose that ground substance composed mainly of collagen fibrils and hyaluronate molecules, which surrounds the cells of Wharton's jelly, prevents the access of the extracting solution to aFGF and bFGF. Although hyaluronate and collagen do not bind aFGF or bFGF directly, they may constitute a barrier which prevents the dispersion of FGFs in Wharton's jelly. Thus, the high concentration of FGFs around the cells of Wharton's jelly may facilitate the interaction of these factors with membrane receptors, thereby resulting in stimulation of cell division and differentiation, as well as of the synthesis of extracellular matrix components.

X-ray effects
Opis:
Concerning the widespread use of X-rays to detect various diseases, such as oral and dental ones, it is essential to study the effects of this radiation on living cells. From the past, genetic effects and cell death because of X-rays have been studied. In addition, the effect of this ionizing radiation on the mechanical properties of the cell and cytoskeleton has been studied, but different results have been obtained based on different models. In this study, post-culture gingival fibroblast cells were classified into two groups of control and radiation with Nano Magnetic Particles functionalized by folic acid. The cells of the radiation group were exposed to X-rays of 3 mGy·cm2 . The specimens were undergone static creep test by a magnetic tweezer. Spring and damper coefficients were obtained based on the viscoelastic solid modeling. The static and dynamic stiffness of the groups was also calculated. The maximum deformation was decreased after radiation from 0.049 ± 0.01 µm to 0.029 ± 0.01 µm and the static stiffness of the model was 1.6 times decreased. Also, the gel point frequency for the control group was 27 Hz and for the radiation group was 7.5 Hz. The results show that the static and dynamic stiffness of the cells decreases after radiation, and less deformation appears in the cells after irradiation. These changes can be due to the breakdown of membrane chemical bonds and activation of actin fibers after radiation.

PLLA
Opis:
Poly-L-lactide (PLLA) is acknowledged biocompatible polyester. However, it possesses high crystallinity/brittleness/stiffness and requires long time for complete degradation. In the current study we present data on PLTMC, a copolymer of L-lactide and trimethylene carbonate (TMC). Poly(trimethylene carbonate) (PTMC) is characterised by good mechanical properties and rapid degradation rate and for this it might possess new desired features for medical applications. During the experiments, adhesion and activity of fibroblasts cultured on PLLA and PLTMC were studied and compared during two time points of 3 and 5 days. On day 3, the number of adherent fibroblasts was compromised when fibroblasts were cultured in the presence of PLTMC but the proper adherence was recovered by day 5. The same pat-tern was observed when we evaluated some activity parameters of fibroblasts. In particular, the release of proteins and nitric oxide was studied as the increased levels of the mediators might indicate unwanted inflammatory-like condition. Overall, the results suggest that the synthesized PLTMC initially shows unwanted effects on fibroblasts but with the time these effects are abolished. Therefore PLTMC seems to represent a new material that is non-cytotoxic and compatible with the living cells.

Opis:
The completely new strategy of pseudophysiological transcomplementary (transcytoplasmic) activation (PP-TCA) of nuclear-transferred oocytes, which had been derived from pWAPhGH-GFPBsd transfected foetal fibroblast cells, was recently applied to the somatic cell cloning of pigs. It resulted in the considerable enhancing not only the cleavage activity of cultured cloned embryos, but also their morula and blastocyst formation rates as compared to the use of standard simultaneous fusion and electrical activation of reconstituted oocytes (77% vs. 57%, 63% vs. 46% and 40% vs. 27%, respectively). Altogether, the use of cytosolic components descended from heterologous (rabbit) zygotes as the agents for stimulation of porcine clonal cytoplasmic hybrids (cybrids) turned out to be reliable and feasible strategy for the generation of transgenic blastocysts by somatic cell nuclear transfer (SCNT). Furthermore, to our knowledge, no previous study has reported the preimplantation developmental outcome of transgenic nuclear-transferred pig embryos following the PP-TCA that was developed and optimised in our laboratory.

For this purpose, the Electric Cell-substrate Impedance Sensing system was used with a prototype substrate containing comb capacitors made of nichrome. Magnetron sputtering, photolithography and etching processes were used to produce the thin-film electrodes. In the experimental part, cells of mouse fibroblast cell line L929 were cultured according to the instruction manual in complete medium, under controlled growth conditions. Inoculation of arrays was carried out by 300 microliters per well of cell suspension at ~1.2×105 cells/ml. The results of the monitoring cells behavior in tissue culture indicate good cell viability and proliferative potential.

The aim of the study was to determine the influence of adenovirus infection on the replication of Marek’s disease virus vaccine strain Rispens/CVI988 during in vitro co-infection studies. Adenovirus field strain JN-5/10j was isolated from sick chickens. The study was conducted in chicken embryo fibroblast cultures (CEF). Monolayers of CEFs were infected with Rispens strain and field adenovirus strain JN-5/10j with different doses (101.0-103.0 TCID₅₀) in the following manner: a) simultaneously, b) first, infection with Rispens strain and after 24 h infection with adenovirus strain JN-5/10j and c) infection with adenovirus strain JN-5/10j 24 h before infection with Rispens strain. After 18, 24, 48, 72, and 96 h of incubation, the copy number of the pp38 gene of Rispens strain was determined using Real-time PCR. The results indicated that the Adenovirus infection before the infection with Rispens strain reduced the replication of the pp38 gene after 48 h by 2 log₁₀.

The experiment included four methods of fixation and three methods of staining and enabled the selection of the best visualization technique for V79 cell lines culture. The Schiff method of colouring with Light Green contrasted well the cell nucleus and the cytoplasm, but the staining was light-sensitive and transient. The Giemsa staining made cell preparations suitable for microscopic evaluation, although the difference between the nucleus and the cytoplasm was not always easily recognisable.
