The article is devoted to the study of the formation of the main approaches to the problem of implementing distance education based on the analysis of scientific publications. The leading role of the idea of the need to introduce distance education is established. The main problem areas identified by the authors of the publications in the analysis of the processes of informatization of education (legal support, monitoring system, performance criteria) are described. The insufficiently covered aspects of the study of the introduction of distance education (the medical aspect, technical problems).

The taxonomic urgency, caused by the combination of the taxonomic gap (wide incompleteness of the taxonomic inventory of living beings on earth) and the biodiversity crisis (major threats of extinction on a large part of the current biodiversity) imposes heavy responsibilities on the scientific community of biologists and particularly of taxonomists. In order to become more efficient in the work of description and naming of the species and other taxa, some changes in traditional working practices should be implemented. Among them, a simplification and standardisation of some nomenclatural Rules and practices, and in particular of the way of writing the scientific names of taxa (nomina) should be considered. Although traditionally considered important, authorship plays no role in the implementation of the nomenclatural Rules concerning availability, allocation and validity of nomina, and the traditional emphasis put on authorship in nomenclature plays in fact a negative role in taxonomy. Removing the names of authors, but not the date, from the nominal-complex by which each taxon is designated would de-emphasise the role of authorship in nomenclature. It would reduce the burden of nomenclatural taxonomic inflation and synonymy load due to nomenclatural mihilim and unwarranted descriptions of new taxa that will later have to be treated as synonyms. Other proposals regarding the standards and length of writing nominal-complexes in publications are offered, which should be beneficial not only to scientific publications using nomina of taxa, but also to the computerisation of nomenclatural information and its electronic diffusion. These proposed changes, some of which are drastic, should not be implemented at once, but in several steps, in order to be progressively adopted by the community of taxonomists.

Magnetic nanoparticles due to their unique magnetic phenomenon, are gaining immense interest due to the utilization of these properties for a wide variety of applications in various arena especially in biomedical field. This book chapter, therefore, summarizes the synthesis of various types of magnetic nanoparticles using different approaches depending of their ability to generate either single core of multcore magnetic nanoparticles. The various biomedical applications of magnetic nanoparticles like Magnetic Resonance Imaging (MRI), drug delivery etc. along with possible limitations and challenges for their extended applications in medicine are also discussed.

Chitosan derivatives, and more specifically, glycosylated derivatives, are nowadays attracting much attention within the scientific community due to the fact that this set of engineered polysaccharides finds application in different sectors, spanning from food to the biomedical field. Overcoming chitosan (physical) limitations or grafting biological relevant molecules, to mention a few, represent two cardinal strategies to modify parent biopolymer; thereby, synthetizing high added value polysaccharides. The present review is focused on the introduction of oligosaccharide side chains on the backbone of chitosan. The synthetic aspects and the effect on physical-chemical properties of such modifications are discussed. Finally, examples of potential applications in biomaterials design and drug delivery of these novel modified chitosans are disclosed.

The interview concerns the role of scientific books in the Italian society from the 19th century until today. Having played an important role in the formation of a national scientific community, science popularization has offered a ceaseless high-quality production during the past two centuries. On the other hand, even today scientific publications do reach only a narrow élite. In the author’s opinion, only the school system has the power to widen the public for science in Italy.

The magnetic nanoparticles are said to be a class of nanoparticles or nanomaterials that can be manipulated by the help of externally applied magnetic field. These magnetic nanoparticles constitute materials such as nickel, cobalt, iron, and their derivatives. These are normally smaller than 1 µm in diameter possess wide range of properties and attractive characteristics suitable for biomedical such as used as hyperthermia, enhancing magnetic resonance imaging (MRI) data, supplementing tissue engineering efforts, and improving the target-based drug delivery and many other technological applications. In the field of cancer research, the role of nanoparticles and nanotechnology-based methods and novel strategies have been increasing swiftly for cancer identification and cancer therapy. The iron oxide (Fe3O4, γ-Fe2O3) nanoparticles (NPs) are widely used for the drug delivery, magnetic nanoparticle-enhanced hyperthermia, and also as MRI contrast agents due to its biocompatibility, low toxicity, etc. lead to the growth of novel biopharmaceutical technologies.

Background: Nanotechnology is a tool being used intensely in the area of drug delivery systems in the biomedical field. Electrospraying is one of the nanotechnological methods, which is growing due to its importance in the development of nanoparticles comprising bioactive compounds. It is helpful in improving the efficacy, reducing side effects of active drug elements, and is useful in targeted drug delivery. When compared to other conventional methods like nanoprecipitation, emulsion diffusion, and double emulsification, electrospraying offers better advantages to produce micro/nanoparticles due to its simplicity, cost-effectiveness, and single-step process. Objective: The aim of this paper is to highlight the use of electrosprayed nanoparticles for biomedical applications. Methods: We conducted a literature review on the usage of natural and synthetic materials to produce nanoparticles, which can be used as a drug delivery system for medical purposes. Results: We summarized a possible key role of electrosprayed nanoparticles in different therapeutic applications (tissue regeneration, cancer). Conclusion: The modest literature production denotes that further investigation is needed to assess and validate the promising role of drug-loaded nanoparticles through the electrospraying process as noninvasive materials in the biomedical field.
