Abstract

Nanofibers, particularly those of a carbonaceous content, have received increased interest in the past two decades due to their outstanding physico-chemical characteristics and their possibility to form and contribute towards a plethora of potentially advantageous materials for consumer, industrial and medical applications. Despite this, and together with the numerous research studies and published articles that have sought to investigate these aspects, the potential impact of CNTs is still not understood. Whether or not nanofibers may be able to provide a sophisticated alternative to conventional materials is still debatable, whilst their effects upon both environmental and human health are highly equivocal. How nanofibers are conceived can determine how they may interact with different environments, such as the human body. Understanding each key step of the synthesis and production of nanofibers to their use within potential applications is therefore essential in gaining an insight into how they may be perceived by any biological system and environment. Thus, obtaining such information will enable all scientific communities to begin to realize the potential advantages posed by nanofibers. The aim of this Special Issue therefore, was to provide a collective overview of nanofibers; ‘from synthesis to application’. The Issue particularly focuses upon carbon-based nanofibers, but also highlights alternative nanofiber types. Emphasis is given holistically, with articles discussing the production routes of nanofibers, their plight during their life-cycle (origin to applied form and effects over time), as well as how nanofibers could either incite conflict, or provide aid to human and environmental health.

Abstract

This Special Issue has been introduced with the aim of offering the possibility to publish new research results from old and new pioneers in the field of bladder cancer basic research. While editing this Special Issue we learned that an enormous enthusiasm is necessary to go on in bladder cancer research. In our eyes, bladder cancer is on one hand a very heterogenous malignancy, which is what makes it so difficult to focus on only one bladder cancer marker in bladder cancer diagnostics and follow-up. On the other hand, it is very important to find prognostic and predictive factors for bladder cancer due to its high incidence and its enormous costs, as one of the most expensive malignancies in the world. Finding and developing new bladder cancer markers is still a very dynamic field. Because there are many of these markers, it is impossible to report all of them. This Special Issue attempts to highlight the role of bladder cancer markers in diagnosis, and the most important biomarkers that have been recently studied and reported. This Special Issue highlights some of the most important markers. Further determination of recurrence and progression markers will contribute to establishing better treatments for individual patients. Molecular staging of urological tumors will allow the selection of cases that will require systemic treatment. It is necessary and important to integrate basic and clinical research under the same objectives.

Abstract

Water covers approximately 71% of the planet’s surface and human activities have been relying on it since remote times. Many traces of these exist under the “zero level” and will continue to exist in the future. Measuring, positioning, and mapping objects under water have experienced very significant modifications, brought about by advances in technology and also by changed requirements, demands for new products, introduction of new tools, and the modification of existing equipment. The exploration, documentation, and recording of underwater environments remains a difficult task, and is sometimes still unsolved. The research, design, and development of techniques and procedures for correctly validating underwater environments are more than ever important.This Special Issue originates from the ISPRS/CIPA Workshop "UNDERWATER 3D RECORDING & MODELING—Experiences in Data Acquisition, Calibration, Orientation, Modelling & Accuracy Assessment” (http://3dom.fbk.eu/files/underwater/index.html) and will accept improved and extended selected papers derived from the workshop’s proceedings, as well as new contributions from international colleagues.We invite you to submit articles on the following topics:Underwater/Multi-media photogrammetryUnderwater platforms (ROV, AUV, robot, etc.)Characterization of underwater passive and active sensorsUnderwater navigation and positioningUnderwater metrology and inspectionsGeometric modeling in multi-media photogrammetryAccuracy requirement and assessment in underwater 3D applicationsRestoration, enhancement and processing of underwater images3D bathymetry techniquesData processing and underwater 3D modelingSensors for marine biology and water pollutionMulti-sensor integration

Abstract

The 8th International Conference on Protein Kinase CK2 (www.uks.eu/ck2), organized by Matthias Montenarh and Claudia Götz, will be held at the Faculty of Medicine of Saarland University, in Homburg, Germany, from 6–9 September, 2016.Protein kinase CK2 is a serine/threonine kinase, which is highly conserved in evolution. Knock-out experiments have shown that this enzyme is absolutely necessary for cell viability. The enzyme is highly expressed in rapidly proliferating cells, which goes along with an elevated enzyme activity. Protein kinase CK2 is involved in a broad range of signaling pathways, regulating proliferation, differentiation, apoptosis, or senescence. Recent advances towards the characterization of the three-dimensional structure of protein kinase CK2 and its subunits will undoubtedly yield important new insights into its regulation, and the functions of CK2. Moreover, with two inhibitors of the enzyme presently in clinical phase II trials, human protein kinase CK2 has appeared as an emerging target for cancer diseases.

Abstract

Antimicrobial peptides (AMPs) are gene-encoded, ancient (and important) mediators of innate host defense that exert direct or indirect antimicrobial action as well as possessing other important biologic activities (e.g., neutralization of endotoxin and anti-biofilm action) that help to protect vertebrates, invertebrates and plants from invading pathogens. While the emergence of multi-antibiotic resistant pathogens (and the desperate need to develop new anti-infectives) has been a recent force driving the field, interest in AMPs has an earlier origin in studies of how phagocytes kill bacteria by oxygen-independent processes. AMPs responsible for such killing of microbes by rabbit and human neutrophils were later purified by Ganz, Selsted and Lehrer, which they termed defensins; at the time of this writing, literally thousands of defensin-based publications can be found in the scientific literature! The initial reports on defensins and the earlier report by Boman’s group on the purification and action of an insect AMP represented a historical and defining point for the AMP field as they, in hindsight, demanded the recognition of AMP research as a unique discipline that has important linkages to other important fields of medicine, especially those of microbiology, infectious diseases and immunology. On a personal note, I remember conferences on phagocytes and host defense in the early 1980s where the topic of AMPs was relegated to one short session in a five day period! Now, we have hundreds of international “AMPologists” with expertise in chemistry, biochemistry, molecular and structural biology, cell biology, microbiology, pharmacology, or medicine who have built their research careers around AMPs and can now attend international conferences dedicated to advances in AMP research.

Abstract

Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes including protein translation and viral packaging. The nucleic acid polymerases may also be responsible for generating genetic diversity that is important for escape from the host’s defenses. The polymerases and other components of the replication machinery may serve as potential anti-viral targets. In this Special Issue, we seek to highlight recent advances into uncovering the structure and function of viral replication complexes. We are especially seeking to highlight the wide-range of methodologies used to gain structural insight into viral replication. Topics of interest include molecular mechanisms of nucleic acid polymerases, nucleic acid recognition and translocation, fidelity and error correction, interactions with lipid membranes, and coordination/regulation of transcription, translation and replication processes.

Abstract

The essential trace element zinc plays indispensable roles in multiple cellular processes. It regulates a great number of protein functions, including transcription factors, enzymes, adapters, and growth factors as a structural and/or catalytic factor. Recent studies have highlighted another function of zinc as an intra- and intercellular signaling mediator, which became recognized as the “zinc signal”. Indeed, zinc regulates cellular signaling pathways, which enable conversion of extracellular stimuli to intracellular signals, and controls various intracellular and extracellular events, and thus zinc mediates communication between cells. The zinc signal is essential for physiology, and its dysregulation causes a variety of diseases, such as diabetes, cancer, osteoarthritis, dermatitis, and dementia.This Special Issue focuses on crucial roles of zinc signaling in biological processes in molecular and physiological basis, addressing the future directions and questions underlying this unique phenomenon. Because there is growing interest and attention in physiopathological contribution of zinc signal, we believe this Special Issue will provide very timely information on it and thus should appeal to a wide range of readers.
