Glycoproteomics: Past, present and future

This invited paper reviews the study of protein glycosylation, commonly known as glycoproteomics, beginning with the origins of the subject area in the early 1970s shortly after mass spectrometry was first applied to protein sequencing. We go on to describe current analytical approaches to glycoproteomic analyses, with exemplar projects presented in the form of the complex story of human glycodelin and the characterisation of blood group H eptitopes on the O-glycans of gp273 from Unio elongatulus. Finally, we present an update on the latest progress in the field of automated and semi-automated interpretation and annotation of these data in the form of GlycoWorkBench, a powerful informatics tool that provides valuable assistance in unravelling the complexities of glycoproteomic studies.     

Serum ferritin: Past,present and future

Background

Serum ferritin was discovered in the 1930s, and was developed as a clinical test in the 1970s. Many diseases are associated with iron overload or iron deficiency. Serum ferritin is widely used in diagnosing and monitoring these diseases.

Scope of review

In this chapter, we discuss the role of serum ferritin in physiological and pathological processes and its use as a clinical tool.

Major conclusions

Although many aspects of the fundamental biology of serum ferritin remain surprisingly unclear, a growing number of roles have been attributed to extracellular ferritin, including newly described roles in iron delivery, angiogenesis, inflammation, immunity, signaling and cancer.

General significance

Serum ferritin remains a clinically useful tool. Further studies on the biology of this protein may provide new biological insights.     

Fungal pathogenesis: Past,present and future

Over the last 20 years a record number of fungal and fungal-like diseases have jeopardized wild species the world over, causing several of the most severe population declines and extinctions ever witnessed (Fisher et al. 2012). Such events include the devastating impact of Batrachochytrium dendrobatidis on amphibian populations and the extinction of bat populations as a result of Geomyces destructans infection. This commentary focusses on two human-infecting fungal pathogens causing much scientific interest, that is, Cryptococcus gattii and Trichophyton rubrum. It summarises recent research findings into their pathogenic evolution and adaptive strategies and highlights key gaps in our knowledge. Finally, the prose attempts to fuse such data with the work of Casadevall, exploiting his theories to predict the future of fungal pathogenesis, that is, where pathogenesis refers to the mechanism that results in disease (Casadevall 2012).     

Classification of vegetation: Past,present and future

Abstract. This paper is a report on the past, status-quo and perspectives of vegetation classification, still a major occupation of many vegetation scientists. The history of vegetation classification is discussed against a background of several controversial issues such as the problem of continuum vs. discontinuum, naturalness vs. arbitrariness of the nature of plant communities, universality vs. ad hoc character of syntaxonomic schemes, as well as classical versus numerical approaches to data analysis for classification purposes. The development of the methodology of vegetation science and the present image of vegetation classification is documented by a bibliometric analysis of the publication record of four majorjournals: Journal of Vegetation Science, Vegetatio, Phytocoenologia and Tuexenia. This analysis revealed a persisting controversy between traditional and numerical approaches to vegetation classification. A series of important changes in vegetation science (foundation of new journals, change of editorial policy by the established, important meetings) punctuate a period called the ‘Innovation period’. Several trends in the development of methods of vegetation systematics are summarized under the headings formalism, pluralism, functionalism, pragmatism and indeterminism. Some new features, such as the development and improvement of numerical tools, use of large data banks and attempts to summarize the theory of vegetation classification are discussed. The new growth-form system of Barkman initiated a revival of physiognomy-based vegetation classification. Within this framework the use of the character-type concept and the development of new numerical methods for studying the hierarchical structure of character-set types seems to be a promising approach. The achievements of population biology and ecophysiology have affected vegetation science by emphasizing the functionality of species within plant communities. The use of guilds and other functional groups has experienced an increasing interest from vegetation scientists. Applied in vegetation science, fuzzy-set theory has bridged the techniques of classification and ordination of plant communities.     

Evolution and development: Past, present, and future

The paper tries to set right certain ideas about the history of evolutionary developmental biology. The main point is, that we had to enface the dominance of a comparative approach towards evolutionary developmental biology before 1900, which even later on was effective in Russia, for example, till the 1930s. The problem of the experimentalist approach set against this tradition was and is that there is no concept of gestalt that may allow to integrate the former comparative views and the modern mechanistic interpretations. We argue, that it would be wrong just to describe the comparative tradition as being outdated, as it may allow to get the framework for a dynamical concept of Gestalt that may integrate the ideas of morphogenesis and pattern formation worked out in evo-devo recently.     

Amperometric enzyme biosensors: Past,present and future

Three groups of the amperometric biosensors such as unmediated, mediated and based on direct transfer of electrons have been thoroughly described, and their advantages and disadvantages were shown. The amperometric biosensors are mostly utilized in commercial devices since they are studied to a greater extent and have some advantages. The modern commercial systems based on amperometric biosensors and its applications have been presented. The major field of employing biosensors is medical diagnostics where numerous commercial devices are currently functioning.     

Therapeutic myocardial angiogenesis: Past, present and future

One of the main goals in the treatment of myocardial ischemia is the development of effective therapy for angiogenesis and neovascularization. The first evidence demonstrating alleviation of myocardial ischemia and increased number of collateral blood vessels was reported in the early 90s following intra-coronary administration of basic fibroblast growth factor protein in canine. This study established the ground for extensive investigations to demonstrate the use of other angiogenic growth factor proteins, genes administered directly or incorporated in viruses, and more recently, endothelial progenitor stem cells (embryonic and adults). The positive results observed in animals failed, in most cases, to repeat themselves in clinical trials in human patients. Therefore, additional experiments are warranted to allow full understanding of the mechanism underlying new blood vessel formation before further clinical studies are undertaken. This review will explore the milestones of angiogenic investigations and their clinical application. (Mol Cell Biochem 264: 75–83, 2004)

European protected areas: Past,present and future

The Habitats Directive celebrates its 20th anniversary in 2012. The influence of the Directive now extends across 27 Member States, compared to just 12 when it was first adopted in May 1992. The sites now cover more than 17% of the land surface of the Member States. However, in spite of their deep roots in human history, reviewed here, and their long-time justification on the basis of intrinsic value, protected areas must face the economic challenges of the modern era. There is a need for policy that can guide decision-making in relation to their continued designation, protection and management, including the ecosystem services that they deliver and taking into account the needs of the local communities who live and work in and around them. Growing pressures include their potential exploitation for economic and commercial benefit and the continued threats from competition over land use and climate change.
