Frequency of Chromosome Healing and Interstitial Telomeres in 40 Cases of Constitutional Abnormalities.

Human telomeres play a major role in stabilizing chromosome ends and preventing fusions. Chromosomes bearing a broken end are rescued by the acquisition of a new telomeric cap without any subtelomeric sequences being present at the breakpoint, a process referred to as chromosome healing. Conversely, a loss of telomeric function or integrity can lead to the presence of interstitial telomeres at the junction site in translocations or ring chromosomes. In order to determine the frequency at which interstitial telomeres or chromosome healing events are observed in target chromosome abnormalities, we conducted a retrospective FISH study using pan-telomeric and chromosome-specific subtelomeric probes on archival material from 40 cases of terminal deletions, translocations or ring chromosomes. Of the 19 terminal deletions investigated, 17 were negative for the subtelomeric probe specific to the deleted arm despite being positive for the pan-telomeric probe. These 17 cases were thus considered as been rescued through chromosome healing, suggesting that this process is frequent in terminal deletions. In addition, as two of these cases were inherited from a parent bearing the same deletion, chromosomes healed by this process are thus stable through mitosis and meiosis. Regarding the 13 cases of translocations and eight ring chromosomes, four and two cases respectively demonstrated pan-telomeric sequences at the interstitial junction point. Furthermore, two cases of translocations and one ring chromosome had both interstitial pan-telomeres and subtelomeres, whereas two other cases of ring chromosomes and one case of translocation only showed interstitial subtelomeres. Therefore, interstitial (sub)telomeric sequences in translocations and ring chromosomes are more common than previously thought, as we found a frequency of 43% in this study. Moreover, our results illustrate the necessity of performing FISH with both subtelomeric and pan-telomeric probes when investigating these rearrangements, as the breakpoints can be either in the distal part of the pan-telomeres, or in between the two types of sequences.

Biochemical Characterization and Bio-evaluation of Collagen and Collagen Peptides Extracted and Purified from Fish Skin: In vitro and In vivo Studies on Antiarthritic and Wound Healing Properties

In fish processing plants, there is huge amount of skin that is left as the waste. When this skin is taken and processed into fish collagen, it will save large amount of money that is used for extraction of collagen from other animal s.Fish collagen can be used as an alternative to replace mammalian collagen, especially collagen extracted from bovine, when we consider the outbreak of bovine spongiform encephalopathy (BSE), transmissible spongiform encephalopathy (TSE) and the foot - and-mouth disease (FMD) issues. BSE and TSE are progressive neurological disorders affecting cattles caused by proteinacious infectious particles called prions.The study aims in producing collagen that has been extracted from fish skin to replace other animal collagen so as to overcome the problem of other animal collagen issues. Also the study utilized the abandoned fish waste produced by fish processing industry since bone, skin, fin and scales of fish can be a useful source of collagen.

Recycling urban waste as possible use for rooftop vegetable garden

Urban authorities in Europe are confronted with increasing demands by urban dwellers for allotment gardens, but vacant urban soil tends to be scarce and/or polluted by past industrial activities. A possible solution for local authorities could therefore be to promote rooftop gardening. However little technical information exists on certain forms of rooftop urban agriculture, called Z-Farming. In 2012, a pilot experiment was run in Paris (France). Simple and cheap systems of rooftop gardening were tested on a rooftop using as crop substrates only local urban organic waste so as to contribute to the urban metabolism. Production levels and heavy metal contents in cropping substrates and edible vegetables were measured. Available results show (i) high levels of crop production with limited inputs compared to land professional gardening, (ii) low levels of heavy metal pollutants in the edible parts of the crops, especially for Cd and Pb with respect to EU norms for vegetables and (iii) positive influence on yields on organizing the substrate in layers and enhancing the biological activity through earthworm inoculation. These encouraging results allow us to consider that rooftop gardening is feasible and seem to have a great potential to improve urban resiliency. It will nevertheless be necessary to identify more precisely the types of roof that can be used and to assess more fully the generic result of the low level of pollution, as well as the global sustainability of these cropping systems.

Peeling, healing and bursting in a lubricated elastic sheet

We consider the dynamics of an elastic sheet lubricated by the flow of a thin layer of fluid that separates it from a rigid wall. By considering long wavelength deformations of the sheet, we derive an evolution equation for its motion, accounting for the effects of elastic bending, viscous lubrication and body forces. We then analyze various steady and unsteady problems for the sheet such as peeling, healing, levitating and bursting using a combination of numerical simulation and dimensional analysis. On the macro-scale, we corroborate our theory with a simple experiment, and on the micro-scale, we analyze an oscillatory valve that can transform a continuous stream of fluid into a series of discrete pulses.

Evaluation of the Larval Therapy in the Healing Process of Infected Wounds with Pseudomonas Aeruginosa in Rabbits

Introduction. During the last two decades the larval therapy has reemerged as a safe and reliable alternative for the healing of cutaneous ulcers that do not respond to the conventional treatments. Objective. To evaluate the use of the larvae of Lucilia sericata as a treatment for infected wounds with Pseudomonas aeruginosa in an animal model. Materials and methods. Twelve rabbits were randomly distributed in 3 groups: the first group was treated with larval therapy; the second was treated with antibiotics therapy and to the third no treatment was applied, therefore was established as a control group. To each animal a wound was artificially induced, and then a suspension of P. aeruginosa was inoculated into the lesion. Finally, every rabbit was evaluated until the infection development was recognized and treatment was set up for the first two groups according with the protocols mentioned above. Macroscopic evaluation of the wounds was based on the presence of edema, exudates, bad odor, inflammation around the wound and the presence of granulation tissue. The healing process was evaluated by monitoring histological changes in the dermal tissue. Results. Differences in the time required for wound healing were observed between the first group treated with larval therapy (10 days) and the second group treated with conventional antibiotics therapy (20 days). Conclusion. The L. sericata larva is and efficient tool as a therapy for infected wounds with P. aeruginosa.

The giant's garden.

Forma parte de una serie de lectura para niños en doce niveles diferentes divididos en historias que todavía están relacionadas con las experiencias de los alumnos y, por tanto, despiertan el interés por la lectura. En este nivel ya se han introducido historias más complejas como ésta de fantasía que trata sobre un gigante que tiene un jardín y al que no le gusta que los niños vayan a jugar en él. Cada cuatro páginas hay juegos de palabras, crucigramas, verdadero-falso y preguntas de selección múltiple para reforzarla comprensión del texto.

The monster garden.

Una historia actual que explora las relaciones sociales y las cuestiones relativas a las futuras orientaciones en la experimentación científica. La cuestión de confianza se plantea también como un factor clave. Frankie Stein vive con su hermano, David, y su papá. Su padre es un ingeniero genético que investiga en un gran laboratorio en lo alto de la colina. El laboratorio cuenta con un montón de guardias de seguridad y se parece algo a una de esas viejas películas de horror. Sus compañeros se burlan de ella y dicen que su padre está creando un mundo de monstruos. El padre está siempre demasiado ocupado para hablar y ella comienza a preguntarse si realmente está trabajando por el bien de la humanidad. Un día, David roba un tubo de ensayo del laboratorio. Él y Frankie deciden repartirlo entre ellos y hacer algunos experimentos en secreto. Frankie acaba por producir una encantadora, alegre criatura llamada Monnie, que le gusta silbar y es experta en mutarse. Al instante Monnie se convierte en su mejor amiga y Frankie comienza a sentirse importante y valiosa casi por primera vez en toda su vida. Frankie no quiere renunciar a Monnie pero Monnie es sólo una extraña creación de un tubo de ensayo.
