Despite its widespread use, little is known regarding the mechanisms by which PRP produces its efficacious effects in some patients.AIM To clarify the effects of PRP on muscular pathologies at the cellular and tissue levels by evaluating the basic science literature.METHODS A systematic review of PubMed/MEDLINE and EMBASE databases was performed using the Preferred Reporting Items for Systematic Reviews and MetaAnalyses(PRISMA) guidelines and checklist. Level III in vivo and in vitro studies examining PRP effects on muscles, myocytes and/or myoblasts were eligible for inclusion. Extracted data included PRP preparation methods and study results.RESULTS Twenty-three studies were included(15 in vivo, 6 in vitro, 2 in vitro/in vivo). Only one reported a complete PRP cytology(platelets, and red and white blood cell counts). Five in vitro studies reported increased cellular proliferation, four reported increased gene expression, and three reported increased cellular differentiation. Five in vivo studies reported increased gene expression, three reported superior muscle regeneration, and seven reported improved histological quality of muscular tissue.CONCLUSION The basic science literature on the use of PRP in muscle pathology demonstrates that PRP treatment confers several potentially beneficial effects on healing in comparison to controls. Future research is needed to determine optimal cytology,dosing, timing, and delivery methods of PRP for muscle pathologies.展开更多

Three factors influenced this process: the acquisition of permanent status from state governments, the establishment of the USGS (United States Geological Survey), and the increase in regional professional scientific societies and publications in the Midwest. These factors aided in the transformation of research projects by state geologists. These projects grew more focused, of higher quality, and increased in number during this time-period. State governments still expected Midwestern geological surveys to meet the practical needs of their respective states as this transformation continued, but surveys complemented these goals with projects more closely related to pure science. This shift encouraged the research goals of surveys to investigate projects more closely related to pure scientific pursuits, and significantly aided in the growth of the earth sciences in the nineteenth Century and early twentieth Century.展开更多

They can be used to measure the different levels of educational outcomes: knowledge, understanding, judgment and problem solving. Traditional MCQs (stand-alone MCQs) often are used as a tool for facts recall. Advantages of using Scenario-based questions (SBQs) include more focus on learning objectives and ability to assess higher levels of learning. Shifting to scenario-based questions can increase the level of difficulty and measure higher levels of cognition. Purpose: This study explores the current knowledge and overall awareness of the undergraduate teaching staff about the use and difficulties of scenario-based single-best answer, multiple-choice questions (SB-SBA-MCQs) in assessments of the basic medical sciences. Method: We used an e-Likert scale questionnaire to explore this issue. The questionnaire covered the current knowledge, experience of staff in writing (SB-SBA-MCQs), courses or postgraduate degrees they attended and difficulties they face or anticipate in writing (SB-SBA-MCQs). Results: The majority (86%) are familiar with courses or workshops related to MCQs writing and assessment in general, a small minority have not attended any. The majority (86%) had some experience in writing MCQs. Only, a small percentage have not tried writing this type of MCQs. Nearly 60% think it takes time to construct, the majority (96%) of those researched are in support of shifting to scenario-based MCQs in basic medical sciences. Conclusion: The study has shown most of the teachers of basic medical sciences are aware of and with good knowledge in (SB-SBA-MCQs). It also highlighted the importance and need for regular training courses and workshops on the same.展开更多

Author considered R-Synthesis as a method for the evaluation oftbe philosophy, philosophy of science, sciences and branches of science. This R-Synthesis includes evaluation of eight categories of general/specific perspective, 21-dimensions, and 12 general subjects (with related scope and contents) for the past 12,000 years. It is a kind of synthesis of science and non-science, physical science and non-physical science, religious science and non-religious science, and others. In this article, author defined 27 possible definitive/certain result cases for this new synthesis. Author defined the possible formation stages shortly to express new disciplines, new constructional and/or complementary theories. These theories are considered to define 21 major effective disciplines. New philosophy perspective is defined (R-Philosophy) shortly. New perspective and sub branches are defined for the philosophy of science. Major sciences are defined due to new basic philosophies. 42-basic components are defined for each science branch. New and/or re-constructed sciences, branches of science, basic sciences, and new hierarchy of science are defined with figure. Electromagnetic sciences, information sciences, and system sciences are defined specifically. Hybrid Sciences, New Era Science, and Ideal Scientific System are defined with general/specific figure.
