We studied the capacity of myelopeptide-4 (regulatory peptide of the bone marrow origin) to induce terminal differentiation of HL-60 and K-562 leukemic cells. Myelopeptide-4 increased the expression of CD14 and CD38 differentiation antigens on the surface of HL-60 cells and of CD44 antigen on K-562 cells, induced the appearance of mature monocyte/macrophages in HL-60 culture and hemoglobin-producing cells in K-562 cell culture, and stimulated phagocytic activity of THP-1 leukemic cells. Myelopeptide-4 is an endogenous factor of cell differentiation, a prospective agent for antileukemic therapy.
There is no doubt that real-world evidence studies have the potential to improve and accelerate the development and delivery of safe and cost-effective innovative medicines to patients as well as influence the way we approach health and health care. Real-world evidence studies are a great challenge in terms of development and conduct, so there should be a good collaboration between the study team and clinical sites at all times, resulting eventually in timely and efficient enrollment. Engaging the sites and key external experts as early as possible during feasibility and routine visits, as well as highlighting the science rationale behind AstraZeneca's portfolio at investigator meetings and during medical science liaison (MSL) interactions, can create a positive impact on physician perception of a particular study and prioritization of patient recruitment in such studies. Therefore, we would like to underline the important role of MSLs in the risk-based monitoring setting of real-world evidence studies, with special attention to the studies with complicated patient profiles, tough timelines, and/or seasonal factors. This approach will be used further for other real world evidence projects of AstraZeneca Russia MC to ensure timelines and budget deliverables are met for the generation of high-quality evidence and eventually better health care for all of us.
Background: The World Health Organization recognizes the antibiotic resistance problem as a major health threat in the twenty first century. The paper describes an effort to fight it undertaken at the verge of two industries—healthcare and Data Science. One of the major difficulties in monitoring antibiotic resistance is low availability of comprehensive research data. Our aim is to develop a nation-wide antibiotic resistance database using Internet search and data processing algorithms using Russian language publications.Materials and Methods: An interdisciplinary team built an intelligent Internet search filter to locate all publicly available research data on antibiotic resistance in Russia and Eurasia countries, extracted it, and collated it for analysis. A database was constructed using data from 850 original studies conducted at 153 locations in 12 countries between 1992 and 2014. The studies contained susceptibility and resistance rates of 156 microorganisms to 157 antibiotic drugs.Results: The applied search methodology was highly robust in that it yielded search precision of 58 vs. 20% in a typical Internet search. It allowed finding and collating within the database the following data items (among many others): publication details including title, source, date, authors, etc.; study details: time period, locations, research organization, therapy area, etc.; microorganisms and antibiotic drugs included in the study along with prevalence values of resistant and susceptible strains, and numbers of isolates. The next stage in project development will try to validate the data by matching it to major benchmark studies; in addition, a panel of experts will be convened to evaluate the outcomes.Conclusions: The work provides a supplementary tool to national surveillance systems in antibiotic resistance, and consolidates fragmented research data available for 12 countries for a period of more than 20 years.
The twentieth century was full of many crises and crisis events in various areas of people's lives. There were crises in science, in particular, physics. There were inter-ethnic, economic, political, financial, social crises, which entailed wars and revolutions. Politicians, sociologists explain, for various reasons and factors, the abundance of crises of the 20th century. But in essence, all crises were the result of the most important crisis of the spiritual, mental and moral crisis, the crisis of consciousness, the soul of an individual.The modern era is characterized by an ecological crisis, a crisis of culture, a crisis of generations of people, a crisis of upbringing, and many, many other crises. At present, all the crises brought mankind to the brink of nuclear and environmental catastrophes.The essence, causes of the emergence of a spiritual crisis, as well as ways out of it to form the scientific foundations of the strategy of holistic sustainable development of an individual, nation, and civilization are considered. Key words: harmony-peace, harmony-love, innovative, cardinal transformation, metamorphosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
