Toward a new Telco role in future content distribution services

International audienceas Content Distribution Services become at the center of network use, OTTs strengthen their dominance over the internet. On the other hand, operators like Telcos see their role shrinking to "dumb pipes" providers. This paper introduces a new Telco role in future content distribution services. In particular, it focuses on the "value" that Telco, as a network operator, can bring to CDN providers and Content providers. Value is assessed with respect to both users' trends and content ecosystem evolution. After our review, we reached two conclusions. Many of Telco assets are likely to be of interest for other content players. An open and efficient control infrastructure is the key for reaching an enhanced business position of the Telco

Retention of Physician Assistants within a Specialty after Completion of a Postgraduate Training Program

Background: The advantages of a specialized training program have led to over 84 postgraduate training programs for Physician Assistants (PAs) covering over 25 specialties. Employee lateral mobility is more prevalent within the PA profession, which allows PA providers to switch between medical specialties. The versatility of PAs promotes higher turnover rates compared to physician counterparts. These high turnover rates can result in increased institutional burden. Postgraduate PA programs provide pre-employment exposure to more in-depth medical training, enabling a well-rounded knowledge base of the PA’s roles and responsibilities, minimizing turnover rates. Purpose: The goal of this survey study is to identify PA graduates’ perceptions of their retention rate, job satisfaction within a given specialty, factors influencing a PA’s decision to change their specialty, and specialty preparation provided by postgraduate training programs and specific educational training. Methods: A mixed method design was utilized to survey both program directors and graduates of PA postgraduate training programs. Results: Of the 398 postgraduate program graduates, 196 (49%) accepted a job within the institution where they trained. Across all postgraduate training programs, 87% of graduates have not changed their specialty since program completion. Ninety-six percent of respondents felt their postgraduate training gave them an accurate preview of employment in their specialty of interest, and all postgraduates would recommend a postgraduate training program to a new PA graduate

Influence of soluble or matrix-bound isoforms of vascular endothelial growth factor-A on tumor response to vascular-targeted strategies

Antiangiogenic therapy based on blocking the actions of vascular endothelial growth factor-A (VEGF) can lead to "normalization" of blood vessels in both animal and human tumors. Differential expression of VEGF isoforms affects tumor vascular maturity, which could influence the normalization process and response to subsequent treatment. Fibrosarcoma cells expressing only VEGF120 or VEGF188 isoforms were implanted either subcutaneously (s.c.) or in dorsal skin-fold "window" chambers in SCID mice. VEGF120 was associated with vascular fragility and hemorrhage. Tumor-bearing mice were treated with repeat doses of SU5416, an indolinone receptor tyrosine kinase inhibitor with activity against VEGFR-2 and proven preclinical ability to induce tumor vascular normalization. SU5416 reduced vascularization in s.c. implants of both VEGF120 and VEGF188 tumors. However, in the window chamber, SU5416 treatment increased red cell velocity in VEGF120 (representing vascular normalization) but not VEGF188 tumors. SU5416 treatment had no effect on growth or necrosis levels in either tumor type but tended to counteract the increase in interstitial fluid pressure seen with growth of VEGF120 tumors. SU5416 pretreatment resulted in the normally fragile blood vessels in VEGF120-expressing tumors becoming resistant to the vascular damaging effects of the tubulin-binding vascular disrupting agent (VDA), combretastatin A4 3-O-phosphate (CA4P). Thus, vascular normalization induced by antiangiogenic treatment can reduce the efficacy of subsequent VDA treatment. Expression of VEGF120 made tumors particularly susceptible to vascular normalization by SU5416, which in turn made them resistant to CA4P. Therefore, VEGF isoform expression may be useful for predicting response to both antiangiogenic and vascular-disrupting therapy

Banca y crisis económica en España, 1930-1935: Un nuevo enfoque

Editada en la Universidad Carlos IIILa historia económica de la Segunda Repúlica española ha recibido un gran empuje en los últimos años, gracias a la publicación de numerosos trabajos, cuyos resultados, sin embargo, han sido contradictorios. En este trabajo se pretende hacer una aproximación al comportamiento de la banca privada española entre 1930 y 1935 desde las nueras teorías económicas del racionamiento del crédito. Las conclusiones tienden a apoyar una explicación de oferta para la caída del volumen de crédito que tuvo lugar.The economic history of the Spanish Second Republic has received a big impulse in the last years, but new research is still required. In the ptesent work we approach the behaviour of the Spanish banking system between 1930 and 1935 on the basis of the new theoríes on credit rationing. The conclusions support a supply side interpretación of the fall in the avalaible amount of creditPublicad

Whole brain radiotherapy with radiosensitizer for brain metastases

<p>Abstract</p> <p>Purpose</p> <p>To study the efficacy of whole brain radiotherapy (WBRT) with radiosensitizer in comparison with WBRT alone for patients with brain metastases in terms of overall survival, disease progression, response to treatment and adverse effects of treatment.</p> <p>Methods</p> <p>A meta-analysis of randomized controlled trials (RCT) was performed in order to compare WBRT with radiosensitizer for brain metastases and WBRT alone. The MEDLINE, EMBASE, LILACS, and Cochrane Library databases, in addition to Trial registers, bibliographic databases, and recent issues of relevant journals were researched. Significant reports were reviewed by two reviewers independently.</p> <p>Results</p> <p>A total of 8 RCTs, yielding 2317 patients were analyzed. Pooled results from this 8 RCTs of WBRT with radiosensitizer have not shown a meaningful improvement on overall survival compared to WBRT alone OR = 1.03 (95% CI0.84–1.25, p = 0.77). Also, there was no difference in local brain tumor response OR = 0.8(95% CI 0.5 – 1.03) and brain tumor progression (OR = 1.11, 95% CI 0.9 – 1.3) when the two arms were compared.</p> <p>Conclusion</p> <p>Our data show that WBRT with the following radiosentizers (ionidamine, metronidazole, misonodazole, motexafin gadolinium, BUdr, efaproxiral, thalidomide), have not improved significatively the overall survival, local control and tumor response compared to WBRT alone for brain metastases. However, 2 of them, motexafin- gadolinium and efaproxiral have been shown in recent publications (lung and breast) to have positive action in lung and breast carcinoma brain metastases in association with WBRT.</p
