Controlled Delivery of Sdf-1 Alpha and Igf-1: Cxcr4(+) Cell Recruitment and Functional Skeletal Muscle Recovery

Therapeutic delivery of regeneration-promoting biological factors directly to the site of injury has demonstrated its efficacy in various injury models. Several reports describe improved tissue regeneration following local injection of tissue specific growth factors, cytokines and chemokines. Evidence exists that combined cytokine/growth factor treatment is superior for optimizing tissue repair by targeting different aspects of the regeneration response. The purpose of this study was to evaluate the therapeutic potential of the controlled delivery of stromal cell-derived factor-1alpha (SDF-1 alpha) alone or in combination with insulin-like growth factor-I (SDF-1 alpha/IGF-I) for the treatment of tourniquet-induced ischemia/reperfusion injury (TK-I/R) of skeletal muscle. We hypothesized that SDF-1 alpha will promote sustained stem cell recruitment to the site of muscle injury, while IGF-I will induce progenitor cell differentiation to effectively restore muscle contractile function after TK-I/R injury while concurrently reducing apoptosis. Utilizing a novel poly-ethylene glycol PEGylated fibrin gel matrix (PEG-Fib), we incorporated SDF-1 alpha alone (PEG-Fib/SDF-1 alpha) or in combination with IGF-I (PEG-Fib/SDF-1 alpha/IGF-I) for controlled release at the site of acute muscle injury. Despite enhanced cell recruitment and revascularization of the regenerating muscle after SDF-1 alpha treatment, functional analysis showed no benefit from PEG-Fib/SDF-1 alpha therapy, while dual delivery of PEG-Fib/SDF-1 alpha/IGF-I resulted in IGF-I-mediated improvement of maximal force recovery and SDF-1 alpha-driven in vivo neovasculogenesis. Histological data supported functional data, as well as highlighted the important differences in the regeneration process among treatment groups. This study provides evidence that while revascularization may be necessary for maximizing muscle force recovery, without modulation of other effects of inflammation it is insufficient.Kinesiology and Health Educatio

Army-NASA aircrew/aircraft integration program. Phase 5: A3I Man-Machine Integration Design and Analysis System (MIDAS) software concept document

This is the Software Concept Document for the Man-machine Integration Design and Analysis System (MIDAS) being developed as part of Phase V of the Army-NASA Aircrew/Aircraft Integration (A3I) Progam. The approach taken in this program since its inception in 1984 is that of incremental development with clearly defined phases. Phase 1 began in 1984 and subsequent phases have progressed at approximately 10-16 month intervals. Each phase of development consists of planning, setting requirements, preliminary design, detailed design, implementation, testing, demonstration and documentation. Phase 5 began with an off-site planning meeting in November, 1990. It is expected that Phase 5 development will be complete and ready for demonstration to invited visitors from industry, government and academia in May, 1992. This document, produced during the preliminary design period of Phase 5, is intended to record the top level design concept for MIDAS as it is currently conceived. This document has two main objectives: (1) to inform interested readers of the goals of the MIDAS Phase 5 development period, and (2) to serve as the initial version of the MIDAS design document which will be continuously updated as the design evolves. Since this document is written fairly early in the design period, many design issues still remain unresolved. Some of the unresolved issues are mentioned later in this document in the sections on specific components. Readers are cautioned that this is not a final design document and that, as the design of MIDAS matures, some of the design ideas recorded in this document will change. The final design will be documented in a detailed design document published after the demonstrations

Pulse of the Pandemic: Iterative Topic Filtering for Clinical Information Extraction from Social Media

The rapid evolution of the COVID-19 pandemic has underscored the need to quickly disseminate the latest clinical knowledge during a public-health emergency. One surprisingly effective platform for healthcare professionals (HCPs) to share knowledge and experiences from the front lines has been social media (for example, the "#medtwitter" community on Twitter). However, identifying clinically-relevant content in social media without manual labeling is a challenge because of the sheer volume of irrelevant data. We present an unsupervised, iterative approach to mine clinically relevant information from social media data, which begins by heuristically filtering for HCP-authored texts and incorporates topic modeling and concept extraction with MetaMap. This approach identifies granular topics and tweets with high clinical relevance from a set of about 52 million COVID-19-related tweets from January to mid-June 2020. We also show that because the technique does not require manual labeling, it can be used to identify emerging topics on a week-to-week basis. Our method can aid in future public-health emergencies by facilitating knowledge transfer among healthcare workers in a rapidly-changing information environment, and by providing an efficient and unsupervised way of highlighting potential areas for clinical research.Comment: 24 pages, 5 figures.

The difficult transition to blended learning in higher education: a Latin American example

En el Centro Universitario de los Valles (CUValles) de la Universidad de Guadalajara (México) se ha implementado un modelo semipresencial, en respuesta a algunas características de la población y de la zona donde se ubica. La investigación es parte de una evaluación realizada con estudiantes y profesores del Centro sobre el modelo. El tratamiento de los datos que se presentan son de tendencia central (media) y distribución porcentual. Los temas de interés que se abordan se relacionan son la aceptación que tiene el modelo, los motivos o razones por el que lo aceptan y la interactividad que tiene el profesorado con los estudiantes. Los datos reflejan que las principales causas o motivos por el que los estudiantes aceptan la semipresencialidad son personales, y reflejan una crítica en la implementación, ya que la mayoría creen que las actividades en línea no sustituyen la presencialidad. Por otro lado, los profesores se quejan de falta de formación para trabajar en un modelo semipresencial y del poco nivel de los estudiantes. La semipresencialidad, es una alternativa viable, para que las universidades presenciales iberoamericanas puedan aumentar su oferta educativa. Pero este tránsito no está exento de riesgos que pueden poner en peligro los posibles beneficios.At Community College "de los Valles" (CuValles), institution from University of Guadalajara (México) a blended e-learning model has been developed. It was in order to satisfy the educational needs of local and regional population. This study, as part of a bigger research, has the aim of evaluating the blended model learning from CuValles. The main analyzed dimensions were the acceptance of model, and the acceptance or not acceptances motives and reasons. Sample included students and lecturers from CuValles, and a descriptive analysis was conducted. The result was that the main acceptance reasons are related to personal factors. Furthermore, several model weaknesses were found: deficit in implementation of nonface-to-face model side, mainly lack of lecturers training, and low level of students training. However, the main conclusion is blended learning is a very powerful learning-teaching system in order to increase the educational level in latin american, although moving from traditional education to this systems has risks

The idea was that those who were trained needed to teach others”: Critical reflections on the 2014 Zambian language of initial literacy policy change

Just before the opening of the school calendar in January 2014, the Zambian government announced a change in language in education policy from English to using a designated official regional Zambian language as the medium of instruction from nursery school to grade 4. Taking this language in education policy change in Zambia as a point of departure, this chapter is a critical reflection on language policy pronouncements in Zambia and in Africa generally. We trace the history of contradictions and contestations surrounding language education policies in Northern Rhodesia (now Zambia) through missionaries, the British South Africa Company, the British Colonial Office and the emergent independent African government administrations. Thereafter, we use observation and interview data from teacher training college lecturers, primary and secondary school teachers of Zambian languages, and Zambian languages subject experts to evaluate the 2014 policy shift. The pedagogical implications of the language policy change are analysed considering language zoning, the monolingual/monoglot ideologies, teacher preparedness, material availability, and the apparent gap between the government-endorsed standard Zambian languages and varieties of the same language and the ‘unofficial’ languages spoken by teachers and learners in multilingual practices. We conclude that, although well-intentioned, the new policy is unlikely to yield the required results of promoting early literacy because it has been implemented before teachers were trained, before material was put in place and it ignored the multilingual dispensations in place

One-step synthesis of highly reduced graphene hydrogels for high power supercapacitor applications

Graphene hydrogels with high electrical conductivity were prepared by a one-step process using hydrazine hydrate as gel assembly agent (GH-HD). Conventional two-step process of gel formation and further reduction to prepare highly conducting gels was replaced by a single step involving equivalent amount of hydrazine. Optimized graphene oxide concentration was established to facilitate such monolith formation. Extensive characterization and control studies enabled understanding of the material properties and gel formation mechanism. The synthesized gel shows a high electrical conductivity of 1141 S/m. The supercapacitor based on GH-HD delivers a high specific capacitance of 190 F/g at a current density of 0.5 A/g and 123 F/g at very high current density of 100 A/g. Furthermore, excellent power capability and cyclic stability were also observed. 3D macroporous morphology of GH-HD makes it ideal for high rate supercapacitor applications
