BMC Medical Genetics , 2008, DOI: 10.1186/1471-2350-9-105
Abstract: We here tested the feasibility of inducing multiexon 45–55 in control and patient muscle cell cultures using various AON cocktails.In all experiments, the exon 45–55 skip frequencies were minimal and comparable to those observed in untreated cells.We conclude that current state of the art does not sufficiently support clinical development of multiexon skipping for DMD.Antisense-mediated exon skipping is emerging as a very promising therapeutic approach for Duchenne muscular dystrophy (DMD) [1]. The aim of this approach is to restore the disrupted reading frame of DMD transcripts, and allow synthesis of partly functional, internally deleted Becker-like dystrophins, rather than prematurely truncated non-functional Duchenne dystrophins. This can be achieved by antisense oligonucleotides (AONs) that target specific exons and hide them from the splicing machinery during pre-mRNA splicing, resulting in the skipping of said exons [2]. Proof of concept of this strategy has been obtained in numerous patient-derived cell cultures with different types of mutations, the mdx mouse model and recently in a first clinical trial where AONs were injected locally in the tibialis anterior muscle of 4 Duchenne patients [1,3-9]. One of the disadvantages of this therapy is its mutation specificity: different exons have to be skipped to restore the reading frame for different mutations [10]. Fortunately, most mutations involve deletions of one or more exons between exon 45 and 53 or between exon 2–20 (50% and 15% of all mutations, respectively) [11]. Therefore, restoration of the reading frame for over 50% of all patients (75% of deletion patients) is theoretically feasible using a strategically selected set of only 10 exons [12]. Skipping of exon 51 is beneficial for the largest group of patients (19% of all deletions, or 13% of all Duchenne patients, (Aartsma-Rus et al. accepted manuscript).Nevertheless, it would be more straightforward if a single formulation of AONs would be applicable

Open Journal of Social Sciences (JSS) , 2018, DOI: 10.4236/jss.2018.612021
Abstract: Dazhou is a large industrial and agricultural city with a huge population. The proportion of service industry in GDP is lower than the secondary industry. Compared with the overall level of the whole country, there is a big gap, and the development potential of service industry is huge. There are three major obstacles to the supply-side reform of the service industry in Dazhou: unsuitable institutional supply and transformational development, uncoordinated consumption supply and market demand, and unbalanced talent supply and development needs. In order to solve these problems, it is required to strengthen the supply of the system, accumulate the power of transformation, improve the quality of supply, guide the return of consumption, strengthen the supply of talents, and create a dynamic state of Dazhou to promote the transformation and upgrading of the service industry. While maintaining the growth rate of the service industry, it must integrate with agriculture and industry, and provide services for the development of agriculture and industry and a platform to foster the new vitality of Dazhou’s economic development.

Abstract: nning a marathon from -45°C to +55°C in a climate chamber: a case study Case report (1119) Total Article Views Authors: K lin K, Knechtle B, Rüst CA, Mydlak K, Rosemann T Published Date October 2012 Volume 2012:3 Pages 131 - 145 DOI: http://dx.doi.org/10.2147/OAJSM.S36808 Received: 07 August 2012 Accepted: 03 September 2012 Published: 25 October 2012 Kaspar K lin,1 Beat Knechtle,1,2 Christoph Alexander Rüst,1 Karsten Mydlak,3 Thomas Rosemann1 1Institute of General Practice and Health Services Research, University of Zurich, Zurich; 2Gesundheitszentrum St Gallen, St Gallen, Switzerland; 3Gemeinschaftslabor Cottbus, Medizinisches Versorgungszentrum für Labormedizin, Mikrobiologie und Infektionsepidemiologie, Cottbus, Germany Background: We describe a runner who completed a self-paced marathon (42.195 km) in a climate chamber with a temperature difference of 100°C, starting at an ambient temperature (Tambient) of 45°C and finishing at an Tambient of +55°C. Methods: Tambient was set at 45°C at the start, and was steadily increased at a rate of 1°C at 4.5-minute intervals to +55°C. Before the start, after every 10.5 km, and at the end of the marathon, body mass, urine, and sweat production were measured and samples of venous blood and urine were collected. The runner’s temperature was recorded every 10 seconds at four sites, ie, the rectum for body core temperature (Tcore), and at the forehead, right wrist, and right ankle for surface temperatures (Tskin). Results: The subject took 6.5 hours to complete the marathon, during which Tcore varied by 0.9°C (start 37.5°C, peak 38.4°C). The largest difference (Δ) of Tskin was recorded at the ankle (Δ16°C). The calculated amount of sweat produced increased by 888% from baseline. In the blood samples, myoglobin (+250%) showed the highest change. Of the pituitary hormones, somatotropic hormone (+391%) and prolactin (+221%) increased the most. Regarding fluid regulation hormones, renin (+1145%) and aldosterone (+313%) showed the greatest increase. Conclusion: These results show that running a marathon in a climate chamber with a total ΔTambient of 100°C is possible, and that the Tambient to Tcore relationship is maintained. These results may offer insight into regulatory mechanisms to avoid hypothermia and hyperthermia. The same study is to be performed using more subjects with the same characteristics to validate the present findings.

Science of Sintering , 2004, DOI: 10.2298/sos0402105s
Abstract: Cobalt and nickel alloy powders were obtained by electrochemical deposition on a titanium cathode from an ammonium solution of cobalt and nickel sulfate. Powders of a specific chemical structure and composition, particle shape and size were obtained by an appropriate choice of electrolysis parameters, current density, deposit growth rate and solution temperature and composition. Within the current density range of 5 - 450 mAcm-2, the current density did not significantly affect the chemical composition of the powders, but had a significant effect on the particle structure, shape and size. Crystal particles formed at a current density lower than 30 mAcm-2. Amorphous powders were obtained at a current density higher than 50 mAcm-2. Structural changes of the obtained amorphous powder of 55mol.% Ni, 45 mol.% Co, pressed under the pressure of 100 MPa, were investigated by measuring the temperature dependence of electrical resistance in isothermal and non-isothermal conditions varying from room temperature to 750°C. The process of thermal stabilization of defects that appeared during pressing occurred within the temperature range of 200-390 C. The DSC method was used to determine that the powder crystallization process occurred in two stages with peak temperatures of the exothermal maximum in the first and second stage of T1 = 438 C and T2 = 573 C, respectively. A distinct correlation between the change of electrical resistance and the crystallization process was established. The reduction of electrical resistively occurs during each crystallization stage.

Abstract: The structure change of Cu55Zr45 metallic glass during natural and artificial ageing was investigated with EXAFS method. For comparison, the structure of quenched specimen was also determined. The corresponding phenomena after the specimen was aged artificially was studied with the small angle X-ray scattering and DSC, which are suitable for observing structure relaxation. Finally, according to the facts observed, a model of phase separation was suggested to explain the EXAFS of the specimens and their change during ageing.
