Phospholipids as dynamic participants in biological processes.
Phospholipids are described as active biological molecules. Three distinctly different roles are examined. The first centers on protein-lipid interactions and the lipid requirement expressed by certain enzymes. This category is illustrated by two soluble proteins of the blood coagulation scheme, Factor IXa and Factor Xa, and by an integral membrane protein, the (Ca2+ + Mg2+)-ATPase of human ery...
متن کاملtRNAs as regulators of biological processes
Transfer RNAs (tRNA) are best known for their role as adaptors during translation of the genetic code. Beyond their canonical role during protein biosynthesis, tRNAs also perform additional functions in both prokaryotes and eukaryotes for example in regulating gene expression. Aminoacylated tRNAs have also been implicated as substrates for non-ribosomal peptide bond formation, post-translationa...
متن کاملPhotoactivated biological processes as quantum measurements.
We outline a framework for describing photoactivated biological reactions as generalized quantum measurements of external fields, for which the biological system takes on the role of a quantum meter. By using general arguments regarding the Hamiltonian that describes the measurement interaction, we identify the cases where it is essential for a complex chemical or biological system to exhibit n...

در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...
15 صفحه اولSemiotic modelling of biological processes: Semiosis as an emergent process
General abstract: Here we introduce biosemiotics as a field of research that develops models of life processes focusing on their informational aspects. Peirce’s general concept of semiosis can be used to analyze such processes, and provide a powerful basis for understanding the emergence of meaning in living systems, by contributing to the construction of a theory of biological information. Pei...
