A wide range of ?elds within supramolecular chemistry are of current and great interest ranging from nanosciences, medicinal sciences, biosciences, and even organic sciences and this is a mature and extremely active area of research. In 1978, Lehn de?ned this chemistry as the \"chemistry of molecular assemblies and of the intermolecular bond.\" In other words, supramolecular chemistry is noncovalent chemistry based upon covalent chemistry. On the other hand, it is well known that replacing the carbon atom of cyclic compounds can lead to dramatic changes in chemical and physical properties and the principles of homocyclic chemistry are often of limited value and may even lead to incorrect results. This is often indeed the case in supramolecular chemistry. The modern explosion of nonochemistry is highly based upon the fundamental recognition of intermolecular interactions engendered by supramolecular scientists. In this volume entitled Heterocyclic Supramolecules I, a part of the series Topics in Heterocyclic Chemistry, some selected topics in noncovalent ch- istry from the last decade are highlighted, with attention particularly focused on heterocyclic supramolecules as well as heterocycle-based nanosciences. The ?rst chapter, \"Molecular Recognition with designed Heterocycles and their Lanthanide Complexes\" by S. Mameri, S. Shinoda, and H. Tsukube - scribes various synthetic receptors for speci?c binding of cationic anionic guests mainly in the solution states. Furthermore, special attention is directed at the heterocycle-lanthanide complexes that worked as luminescent sensory devices of biologically important anions. Thus, \"rare\" earth metals are making the change into \"hopeful\" earth metals.

The main difference between DNA damage and mutation is that DNA damage is a structural change in DNA whereas mutation is a change in the nucleotide sequence of DNA. Furthermore, DNA damage prevents DNA replication while mutation alters the genetic information encoded by DNA
The construction of mathematical models is an essential scientific activity. Mathematics has long been associated with developments in the exact sciences and engineering, but more recently mathematical modelling has been used to investigate complex systems that arise in many other fields. The contributors to this book demonstrate the application of mathematics to modern research topics in ecology and environmental science, health and medicine, phylogenetics and neural networks, theoretical chemistry, economics and management.

Cells are what make up the body. There are, in fact, billions of these cells that serve as the basic structural and functional unit of all kinds of organisms. Inside each cell, you’ll find a nucleus where the chromatin is found. The main composition of chromatin is deoxyribonucleic acid or DNA and other types of
Mitochondrial dysfunction(s) (MDs) can be defined as alterations in the mitochondria, including mitochondrial uncoupling, mitochondrial depolarization, inhibition of the mitochondrial respiratory chain, mitochondrial network fragmentation, mitochondrial or nuclear DNA mutations and the mitochondrial accumulation of protein aggregates. All these MDs are known to alter the capacity of ATP production and are observed in several pathological states/diseases, including cancer, obesity, muscle and neurological disorders. The induction of MDs can also alter the secretion of several metabolites, reactive oxygen species production and modify several cell-signalling pathways to resolve the mitochondrial dysfunction or ultimately trigger cell death. Many metabolites, such as fatty acids and derived compounds, could be secreted into the blood stream by cells suffering from mitochondrial alterations. In this review, we summarize how a mitochondrial uncoupling can modify metabolites, the signalling pathways and transcription factors involved in this process. We describe how to identify the causes or consequences of mitochondrial dysfunction using metabolomics (liquid and gas chromatography associated with mass spectrometry analysis, NMR spectroscopy) in the obesity and insulin resistance thematic.
