Opis:
Regenerative medicine is focusing on searching for stem cells, which can be efficiently and safely used for regeneration of damaged tissues and organs. Pluripotent stem cells would be ideal for this purpose. It is because they have the ability to differentiate into cells of all three germ layers (ecto-, meso- and endoderm). One of the sources of their isolation are embryos. For many years, they are made unsuccessful attempts to use of very controversial embryonic stem cells that are isolated from embryos. So strong ethical controversy forced scientists to look for other, undoubted ethically, sources of pluripotent stem cells. Induced pluripotent stem cells are proposed, as a more promising alternative to cells isolated from embryos. Unfortunately, both embryonic stem cells and induced pluripotent stem cells tend to genetic instability leading to the formation of teratomas. In parallel studies scientists try to use of stem cells isolated from adult tissues (e.g. bone marrow cells or adipose tissue) in the regeneration of parenchymal organs. Unfortunately, there is no convincing evidence for most of these cells that can regenerate damaged parenchymal organs. Regenerative medicine more frequently is employed in the otorhinolaryngological therapies. More and more researchers’ efforts are put into the development of an effective method of stimulation (in vitro) of pluripotent stem cells isolated from adult tissue for differentiation of the renewable progenitor stem cells which can keep their potential after transplantation into the recipient (e.g. in the treatment of imbalances or hearing loss). Moreover, there are promising methods for employing of the stem cells potential in tissue engineering as they are more effectively introduced as a clinical therapies.

Opis:
Stem cells are self-renewing cells that can differentiate into specialized cell type(s). Pluripotent stem cells, i.e. embryonic stem cells (ESC) or induced pluripotent stem cells (iPSC) differentiate into cells of all three embryonic lineages. Multipotent stem cells, like hematopoietic stem cells (HSC), can develop into multiple specialized cells in a specific tissue. Unipotent cells differentiate only into one cell type, like e.g. satellite cells of skeletal muscle. There are many examples of successful clinical applications of stem cells. Over million patients worldwide have benefited from bone marrow transplantations performed for treatment of leukemias, anemias or immunodeficiencies. Skin stem cells are used to heal severe burns, while limbal stem cells can regenerate the damaged cornea. Pluripotent stem cells, especially the patient-specific iPSC, have a tremendous therapeutic potential, but their clinical application will require overcoming numerous drawbacks. Therefore, the use of adult stem cells, which are multipotent or unipotent, can be at present a more achievable strategy. Noteworthy, some studies ascribed particular adult stem cells as pluripotent. However, despite efforts, the postulated pluripotency of such events like "spore-like cells", "very small embryonic-like stem cells" or "multipotent adult progenitor cells" have not been confirmed in stringent independent studies. Also plasticity of the bone marrow-derived cells which were suggested to differentiate e.g. into cardiomyocytes, has not been positively verified, and their therapeutic effect, if observed, results rather from the paracrine activity. Here we discuss the examples of recent studies on adult stem cells in the light of current understanding of stem cell biology.

Opis:
The embryonic architecture, which draws inspiration from the biological process of ontogeny, has built-in mechanisms for self-repair. The entire genome is stored in the embryonic cells, allowing the data to be replicated in healthy cells in the event of a single cell failure in the embryonic fabric. A specially designed genetic algorithm (GA) is used to evolve the configuration information for embryonic cells. Any failed embryonic cell must be indicated via the proposed Built-in Selftest (BIST) the module of the embryonic fabric. This paper recommends an effective centralized BIST design for a novel embryonic fabric. Every embryonic cell is scanned by the proposed BIST in case the self-test mode is activated. The centralized BIST design uses less hardware than if it were integrated into each embryonic cell. To reduce the size of the data, the genome or configuration data of each embryonic cell is decoded using Cartesian Genetic Programming (CGP). The GA is tested for the 1-bit adder and 2-bit comparator circuits that are implemented in the embryonic cell. Fault detection is possible at every function of the cell due to the BIST module’s design. The CGP format can also offer gate-level fault detection. Customized GA and BIST are combined with the novel embryonic architecture. In the embryonic cell, self-repair is accomplished via data scrubbing for transient errors.

Purpose: In the present study, we aimed to identify the effect of three increasing doses of most widely preservative, formaldehyde (FA) on the urinary system using human embryonic kidney cells (HEK-293) in vitro. Materials and methods: The HEK-293 cells were grown in Dulbecco’s Modified Eagle medium (DMEM, Gibco, USA) supplemented with 10% of fetal bovine serum, 100 IU/ml penicillin and 100 μg/ml of streptomycin (Gibco, USA) using 25cm2 flasks (Nunc, Denmark), in a CO2 incubator (Heal Force) at 37°C are treated with 19 % formaldehyde in DMEM supplemented with 10% of fetal bovine serum to yield final concentrations of 0.05 μl/ml, 0.1 μl/ml, 0.5 μl/ml and 1.0 μl/mlof 19% FA. Results: The result showed that statistically significant dose dependent decrease in cell viability of HEK-293 cells with exposure to increasing concentration of FA (0.05 μl/ml, 0.1 μl/ml, 0.5 μl/ml and 1.0 μl/ml) on MTT assay. Extremely huge dose dependent DNA damage with a dose dependent up regulation of mRNA expression of pro-apoptotic iNOS and TNF- gene was observed when HEK-293 cells are treated with the increasing concentration of FA. In addition, the protein expression levels of Bcl-2 and Bax revealed that increasing concentration of FA on HEK-293 cells down regulated the anti-apoptotic Bcl-2 and up regulated pro-apoptotic Bax gene. Conclusions: Our result indicates that, high dose of FA is more dangerous than the low dose on HEK-293 cells with cellular damage.

Opis:
This study describes 18 specimens representing the earliest growth parts of orthoceratoid cephalopods, most of which have been recently obtained from the Middle Ordovician strata of the Prague Basin, central Bohemia. Only about 20 specimens of Ordovician orthoceratoids displaying embryonic shell are known globally and the Bohemian material thus significantly expands their current record. The studied collection includes twelve specimens assigned to the species Bactroceras sandbergeri and shows that the morphological variability in early ontogenetic growth stages of this species was rather low. The absence of a cicatrix was definitely confirmed in this phylogenetically important cephalopod. Six other specimens investigated herein are indeterminate orthoceratids. Initial chambers, where preserved, are generally large compared to known, stratigraphically younger specimens. This is interpreted here as supporting the previously postulated trend of decreasing the egg- and hatchling sizes in orthoceratoid cephalopods from mid-Ordovician times onwards. Alternatively, the large sizes of these Bohemian orthoceratids may be explained by the position of the Prague Basin in relatively cool-water high palaeolatitudes during the Middle Ordovician.

Opis:
This study was carried out to determine the time-dependent changes in the ultrasonographic image of the ovary with computer-assisted analysis programs at certain intervals after ovulation and to determine whether computer-assisted analysis programs and ovulation programs can be managed in cases where the ovulation time is unknown. The study included 40 purebred Arab mares. The study was subdivided into 4 different time periods of 6 (Group 1), 12 (Group 2), 18 (Group 3) and 24 (Group 4) hours following ovulation. In addition, after ovulation and ultrasonographic examination, natural insemination was performed at 6, 12, 18 and 24 hours, and pregnancy examination and follow-up were performed at 15-30-45 days. In the echotexture analysis, mean grayness value (MGV) and contrast (CON) measurements were at different levels according to the time groups (p<0.001). Homogeneity (HOM) measurements were at different levels according to the time groups (p<0.001). A very strong, significant negative correlation was determined between MGV and pregnancy rates (r=-0.91, p=0.01, p<0.05). No significant relationship was observed between HOM values and pregnancy rates (r=0.19, p=0.23, p>0.05). A very strong, significant negative correlation was determined between CON and pregnancy rates (r=-0.92, p=0.01, p<0.05). It was concluded that the use of ultrasonographic echotexture in mares after ovulation provided very important information. In cases where the time of ovulation was not known, by looking at the values of echotexture parameters, it was seen that the highest pregnancy rates were at the 6th hour and the lowest pregnancy rates were at the 24th hour. As the echotexture parameters MGV and CON increased, it was determined that pregnancy rates decreased, but there was no relationship between them and the HOM value.

Opis:
Cellular retinoic acid binding proteins are considered to be involved in retinoic acid (RA) signaling pathways. Our aim was to compare the expression and localization of cellular retinoic acid binding proteins I and II (CRABP I and II) in embryonic mouse hearts during normal development and after a single teratogenic dose of RA. Techniques such as real-time PCR, RT-PCR, Western blots and immunostaining were employed to examine hearts from embryos at 9-17 dpc. RA treatment at 8.5dpc affects production of CRABP I and II in the heart in the 48-h period. Changes in expression of mRNA for retinaldehyde dehydrogenase II (Raldh2), Crabp1 and Crabp2 genes also occur within the same time window (i.e. 10-11dpc) after RA treatment. In the embryonic control heart these proteins are localized in groups of cells within the outflow tract (OT), and the atrioventricular endocardial cushions. A gradient of labeling is observed with CRABP II but not for CRABP I along the myocardium of the looped heart at 11 dpc; this gradient is abolished in hearts treated with RA, whereas an increase of RALDH2 staining has been observed at 10 dpc in RA-treated hearts. Some populations of endocardial endothelial cells were intensively stained with anti-CRABP II whereas CRABP I was negative in these structures. These results suggest that CRABP I and II are independently regulated during heart development, playing different roles in RA signaling, essential for early remodeling of the heart tube and alignment of the great arteries to their respective ventricles.

Functional modeling of human genes and diseases requires suitable mammalian model organisms. For its genetic malleability, the mouse is likely to continue to play a major role in defining basic genetic traits and complex pathological disorders. Recently, gene targeting techniques have been extended towards developing new engineering strategies for generating extensive lesions and rearrangements in mouse chromosomes. While these advances create new opportunities to address similar aberrations observed in human diseases, they also open new ways of scaling-up mutagensis projects that try to catalogue and annotate cellular functions of mammalian genes.

Characterization studies of NPs were performed. Permeability of insulin and the effect of ESC on pancreatic beta cells were investigated. by the determination of Insulin or glucose levels were determined and histologic investigations were also performed. ESC encapsulation efficiency was calculated by western blot analysis. The particle sizes of insulin and ESC-loaded-NPs were determined as 0.665±0.202 µm and 0.650 ±0.310 µm. The mean zeta potentials of insulin and ESC-loaded-NPs nanoparticles were found as 6.88±0.729 mV, 5.13±0.631 mV. The polydispersity index of insulin and ESC nanoparticles were 0.660±0.175, 0.620±0.205 respectively. Encapsulation efficiency of insulin and ESC-loaded-NPs were found to be 50±1.53% and 51%. Insulin release from nanoparticles was found to be 72.8% over 48h. The gGlucose concentrations wasere decreased to 201 and 202.7 mg/dl from 250 mg/dl in streptozocin (STZ) induced diabetic mice group after insulin and ESC-loaded-NPs administration. Insulin and ESC-loaded-NPs improved the blood insulin levels in all experimental groups. These NPs may be used for repairing of pancreatic cells. Healing or some degree of regeneration was observed when insulin and ESC-loaded-NPs were administered to the mice ip. ESC-loaded-NPs can be a potential source for cell replacement therapy in the treatment of diabetes.

Opis:
The study aim was to compare the antagonistic interaction between saprotrophic soil fungi and embryonic development of geohelminths Toxocara canis and Ascaris suum. The experimental cultures were fertilized eggs of T. canis and A. suum incubated together with mycelium of strains: Fusarium culmorum, Metarhizium anisopliae, Paecilomyces fumosoroseus, Trichoderma viride and Trichothecium roseum. In the control cultures the eggs of both nematode species were incubated without fungi. The experiment was conducted at temp. 26ºC for 60 days. Compared with the control, all of the tested species of fungi significantly extended the embryonic development of both T. canis and A. suum. Most inhibitory effect on the rate of embryonic development of T. canis and A. suum had three fungal species: P. fumosoreus, M. anisopliae and T. viride. Compared with the control, on the 60th day of incubation in the presence of each of the tested fungal species, a larger percentage (p<0.05) of morphological abnormalities was stated in developing embryos of T. canis (49–69%) than in A. suum (15.1–67.7%). Among the examined fungal species, only incubation with P. fumosoroseus resulted in significantly greater (p<0.05) incidence of embryonic malformations (embryopathies) in T. canis, as compared with A. suum. Also the percentage of dead larvae of T. canis in the control and in cultures with fungi (12% and 100%, respectively) was significantly higher in comparison with A. suum (0.5% and 10.3–36%, respectively). The highest percentage of non-viable larvae of A. suum was found in the presence of P. fumosoroseus, and the lowest in the presence of M. anisopliae. Findings may indicate that T. canis eggs are more sensitive to antagonistic interaction of the examined fungal strains than A. suum eggs.
