Computational biology involves the development and application of data-analytical and theoretical methods, mathematical modelling and computational simulation techniques to the study of biological, ecological, behavioural, and social systems. Computational biology is different from biological computing , which is a subfield of computer engineering using bioengineering and biology to build computers.

This entry aims to clarify how systems and synthetic biology contribute to and extend discussions within philosophy of science. Unlike fields such as developmental biology or molecular biology, systems and synthetic biology are not easily demarcated by a focus on a specific subject area or level of organization. Rather, they are characterized by the development and application of mathematical, computational, and synthetic modeling strategies in response to complex problems and challenges within the life sciences. Proponents of systems and synthetic biology often stress the necessity of a perspective that goes beyond the scope of molecular biology and genetic engineering, respectively. With the emphasis on systems and interaction networks, the approaches explicitly engage in one of the oldest philosophical discussions on the relationship between parts and wholes, or between reductionism and holism.

Philosophy of Systems and Synthetic Biology

Systems Biology. A biological system is defined as the network of biological entities with a specific function. Although the study of the genome and its expression process remains important, in recent years, researchers have focused on studying the structure and dynamics of an entire biological system. The operation of a system determines the interactions of its individual elements. Understanding the function and interactions of a system is accomplished by comprehension of four basic attributes: 1 structures of the system, including the gene interactions and biochemical pathways, as well as the control mechanisms of the above procedures, 2 system dynamics, containing patterns of the system behavior over time, and the identification of the main mechanisms that control specific behaviors under various conditions, 3 the control method, including configuration of cellular mechanisms in order to reduce dysfunctions, 4 the design method, including techniques for designing and modifying biological systems to reduce errors.

Metrics details. Systems medicine has become a key word in biomedical research. Although it is often referred to as P4- predictive, preventive, personalized and participatory -medicine, it still lacks a clear definition and is open to interpretation. This conceptual lack of clarity complicates the scientific and public discourse on chances, risks and limits of Systems Medicine and may lead to unfounded hopes. Against this background, our goal was to develop a sufficiently precise and widely acceptable definition of Systems Medicine. Full-texts of articles containing Systems Medicine in title or abstract were screened for definitions.

It seems that you're in Germany. We have a dedicated site for Germany. For life to be understood and disease to become manageable, the wealth of postgenomic data now needs to be made dynamic. This development requires systems biology, integrating computational models for cells and organisms in health and disease; quantitative experiments high-throughput, genome-wide, living cell, in silico ; and new concepts and principles concerning interactions. This book defines the new field of systems biology and discusses the most efficient experimental and computational strategies. The benefits for industry, such as the new network-based drug-target design validation, and testing, are also presented.

Essays Biochem 26 October ; 62 4 : — Systems biology is an integrative discipline connecting the molecular components within a single biological scale and also among different scales e. Systems biology uses a wide range of quantitative experimental and computational methodologies to decode information flow from genes, proteins and other subcellular components of signaling, regulatory and functional pathways to control cell, tissue, organ and organismal level functions. The computational methods used in systems biology provide systems-level insights to understand interactions and dynamics at various scales, within cells, tissues, organs and organisms. In recent years, the systems biology framework has enabled research in quantitative and systems pharmacology and precision medicine for complex diseases.

Metrics details. In recent years, parallel developments in disparate disciplines have focused on what has come to be termed connectivity ; a concept used in understanding and describing complex systems. Conceptualisations and operationalisations of connectivity have evolved largely within their disciplinary boundaries, yet similarities in this concept and its application among disciplines are evident. However, any implementation of the concept of connectivity carries with it both ontological and epistemological constraints, which leads us to ask if there is one type or set of approach es to connectivity that might be applied to all disciplines. In this review we explore four ontological and epistemological challenges in using connectivity to understand complex systems from the standpoint of widely different disciplines. These are: i defining the fundamental unit for the study of connectivity; ii separating structural connectivity from functional connectivity; iii understanding emergent behaviour; and iv measuring connectivity. We draw upon discipline-specific insights from Computational Neuroscience, Ecology, Geomorphology, Neuroscience, Social Network Science and Systems Biology to explore the use of connectivity among these disciplines.

Systems biology: a way to make complex problems more understandable

Systems biology is an approach to interrogate complex biological systems through large-scale quantification of numerous biomolecules. Changes in molecular pathways can be detected using high-throughput omics datasets e. Importantly, integration of multiple omic datasets is becoming key to revealing novel biological insights.

И, повернувшись к Большому Брату, нажатием клавиши вызвала видеоархив. Мидж это как-нибудь переживет, - сказал он себе, усаживаясь за свой стол и приступая к просмотру остальных отчетов. Он не собирается выдавать ключи от директорского кабинета всякий раз, когда Мидж придет в голову очередная блажь. Не успел он приняться за чтение отчета службы безопасности, как его мысли были прерваны шумом голосов из соседней комнаты. Бринкерхофф отложил бумагу и подошел к двери. В приемной было темно, свет проникал только сквозь приоткрытую дверь кабинета Мидж.
