The 53rd National Congress of the Italian Society of Biochemistry and Molecular Biology (SIB), which will be held in Riccione from 23 to 26 September, is characterised by the elevated scientific level and interdisciplinary interest of the numerous sessions in which it is organised. The Scientific Programme comprises three joint Symposia of the SIB and the Chemistry of Biological Systems section of the Italian Chemistry Society (SCI) on Molecular Systems Biology, Chemistry of Nucleic Acids, Protein and Drug Structure, and Environmental Biotechnology. These Symposia address groundbreaking arguments, making the joint interest of the two societies particularly fascinating; the joint organisation of these events in fact signals the shared intention to proceed along the path of scientific exchange. The topics of the other sessions have been chosen by the Scientific Committee on the basis of their scientific relevance and topicality, with particular attention paid to the selection of the speakers. The SIB sessions will range from Signal Transduction and Biomolecular Targets, Protein Misfolding and its Relationship with Disease, Emerging Techniques in Biochemistry, Gene Silencing, Redox Signalling and Oxidative Stress, Lipids in Cell Communication and Signal Transduction, Mitochondrial Function and Dysfunction.

Iron is an essential element for almost all organisms, a cofactor playing a crucial role in a number of vital functions, including oxygen transport, DNA synthesis, and respiration. However, its ability to exchange electrons renders excess iron potentially toxic, since it is capable of catalyzing the formation of highly poisonous free radicals. As a consequence, iron homeostasis is tightly controlled by sophisticated mechanisms that have been partially elucidated. Because of its biological importance, numerous disorders have been recently linked to the deregulation of iron homeostasis, which include not only the typical disorders of iron overload and deficiency but also cancer and neurodegenerative diseases. This leads iron metabolism to become an interesting therapeutic target for novel pharmacological treatments against these diseases. Several therapies are currently under development for hematological disorders, while other are being considered for different pathologies. The therapeutic targeting under study includes the hepcidin/ferroportin axis for the regulation of systemic iron homeostasis, complex cytosolic machineries for the regulation of the intracellular iron status and its association with oxidative damage, and reagents exploiting proteins of iron metabolism such as ferritin and transferrin receptor. A promising potential target is a recently described form of programmed cell death named ferroptosis, in which the role of iron is essential but not completely clarified. This Special Issue has the aim to summarize the state-of-the-art, and the latest findings published in the iron field, as well as to elucidate future directions.

Chlorophyll, a green pigment present in almost all plants, algae, and cyanobacteria, is a significant biomolecule essential to photosynthesis, the process by which plants convert light into energy. This book provides a comprehensive and easy-to-understand source of information on the latest developments in chlorophyll research. It is a collection of contributions from leading specialists in the subject. Topics discussed include the medicinal uses of chlorophyll, the electronic structure of chlorophyll monomers and oligomers, and chlorophyll estimate from fluorescence vertical profiles in the ocean.
