What is Stem cell therapy?3 answersStem cell therapy is a multidisciplinary field of medicine that involves the introduction of new adult stem cells into damaged tissue to treat disease or injury. It has potential applications in various conditions such as Alzheimer's disease, Parkinson's disease, spinal cord injury, heart disease, severe burns, and diabetes. Stem cells can repair or replace damaged neurons, organs, and tissues. They are also used in basic research to understand human development, cancer, and gene control, as well as to test new drugs. The regulation of stem cell therapy is crucial for patient safety and quality healthcare, involving governing bodies such as the World Health Organization and governmental regulatory bodies. Stem cell therapy facilities must adhere to structural and technical regulations, including good tissue practice and good manufacturing practice, equipment calibration, skilled personnel, standard operating procedures, and quality control systems. Stem cell therapy shows promise in the treatment of cancer by providing targeted drug delivery and enhancing tumor volume reduction and survival rates. It is also being explored as a potential treatment for central nervous system disorders such as epilepsy and post-traumatic stress disorder.
How does artificial intelligence work?5 answersArtificial intelligence (AI) is the ability of computers to perform tasks typically associated with intelligent beings. It involves machine learning and deep learning, which are applications of AI. AI technologies are designed to imitate human cognitive abilities, enabling computers to deal with complex and ill-defined problems in an intelligent and adaptive manner. In manufacturing, AI is used to increase productivity, reduce errors, and improve efficiency. It can detect defects in production lines, ensure correct configuration of parts, and optimize workflows. AI also has applications in journalism, where it can be used to find hidden patterns in large volumes of data, reducing the cost of investigative journalism. Municipalities in the Nordic regions are adopting AI for various purposes, such as using chatbots to answer citizen questions and predicting leaks in water and sewage networks.
How does sociology work?3 answersSociology is a social science that focuses on society, human social behavior, patterns of social relationships, social interaction, and aspects of culture associated with everyday life. It uses various methods of empirical investigation and critical analysis to develop a body of knowledge about social order and social change. Sociology seeks to fit observations of social phenomena into different conceptual systems, tracing its origins from Enlightenment thought to subsequent developments in various sociological thinkers. It also examines the array of concepts and methods of research that have been applied to the study of society. Sociology offers a more rigorous understanding of the social and can help dismantle commonly shared preconceived ideas about the social order. It provides valuable insights into the social institutions and processes that shape human behaviors, histories, and opportunities. Sociology teaches students how to use empirical data to understand current social realities and act effectively on the central issues of our time. Sociology studies human society from the smallest of social interactions to the emerging global society, focusing on interpersonal, societal, and global scales.
What are the sources of stem cells?3 answersStem cells can be obtained from various sources such as bone marrow, adipose tissue, Wharton jelly, peripheral blood, cord blood, and tissue-specific stem cells. Hematopoietic stem cells, specifically, can be obtained from bone marrow, peripheral blood, or umbilical cord blood. Endothelial progenitors are present in bone marrow, adipose tissue, cord blood, and tissue. Mesenchymal stem cells can be procured from different tissue sources including umbilical cord, synovial tissue, breast milk, menstrual blood, adipose tissue, bone marrow, and dentine pulp. Perinatal stem cells, on the other hand, can be derived from perinatal tissues such as the placenta, amnion, amniotic fluid, umbilical cord blood, and Wharton's jelly. These various sources of stem cells offer different characteristics and potential therapeutic applications.
How the stem cell theraoy done?4 answersStem cell therapy involves the use of stem cells to repair tissue in various organs of the body. The method described in one study involves intraluminally applying stem cells through a natural body vessel or duct leading to the target site of the tissue to be repaired. Another study focuses on the preparation of stem cell spheres by applying a liquid crystal state material to the surface of a cell culture container and implanting stem cells onto this material. A different approach involves culturing stem cells by introducing them into an amnion epithelial cell feeder layer and culturing them in a culture solution. Stem cells can also be isolated from mammals with haemangioma and used in various therapeutic methods, including systemic or direct implantation into a subject or further in vitro culture and differentiation. Stem cell plasticity is another important aspect, where stem cells from different sources can contribute to the recovery of damaged organs.
