Original Classification

Classically, the accessory nerve is described as having a cranial and a spinal root. Textbooks are inconsistent with regard to the modality of the spinal root of the accessory nerve. Some authors report the spinal root as general somatic efferent (GSE), while others list a special visceral efferent (SVE) modality. We investigated the comparative, anatomical, embryological, and molecular literature to determine which modality of the accessory nerve was accurate and why a discrepancy exists. We traced the origin of the incongruity to the writings of early comparative anatomists who believed the accessory nerve was either branchial or somatic depending on the origin of its target musculature. Both theories were supported entirely by empirical observations of anatomical and embryological dissections. We find ample evidence including very recent molecular experiments to show the cranial and spinal root are separate entities. Furthermore, we determined the modality of the spinal root is neither GSE or SVE, but a unique peripheral nerve with a distinct modality. We propose a new classification of the accessory nerve as a transitional nerve, which demonstrates characteristics of both spinal and cranial nerves.

Original Classification

It has been over 30 years now since the original classification of femoral artery aneurysms by Darning and Cutler to type 1 and 2. We have demonstrated in a case report that it is time for amendment of this classification. Isolated profunda aneurysm do exist as separate entity, and they can be managed by complete exclusion from the circulation provided the presence of patent superficial femoral artery and good runoff circulation, without any ill effects.

Introduction: The term “bioceramic” is used in endodontics to describe various products and is often used in general terms for mineral trioxide aggregate (MTA) and other hydroscopic dental cements (HDC), which creates confusion in the terminology. Aim: The aim of the study is to present a definition and an original classification of bioceramic endodontic sealers. Materials and methods: A total of 123 articles were found by the PubMed search engine using the key phrase “bioceramic endodontic sealers”. Of these 123 articles, we analyzed 20 articles that contain information about the composition, properties, definition, and classification of bioceramic endodontic sealers. Results: In accordance with the collected data on the composition and the delivery form of calcium silicate endodontic sealers, we propose a new definition of bioceramic endodontic sealers that clarifies the specificities of these materials. In the new classification they are divided by two criteria: source of calcium silicate and form of delivery. It also contains the particular products’ names in order to aid their usage in the clinical practice.  Conclusions: The new definition of bioceramic endodontic sealers clears out the confusion in the terminology, which promotes the classification of these products and helps understanding their clinical application.

The article deals with the influence of presidents in the government formation process (GFP). The authors propose an original classification of roles of presidents, reflecting real constitutional practice, with five categories based on real presidential influence on the GFP, from the weakest to the strongest: observer, notary, regulator, co-designer, and creator. This classification is applied to Czechia, where the formal constitution gives the president great opportunities to intervene in the GFP. The results of the analysis of all cases of GFP show a significant variety of roles the Czech presidents have played: from notary to creator. Two factors are particularly important. Firstly, the timing of elections proved significant. When the GFP directly followed parliamentary elections, the presidents were weaker. In contrast, if the GFP followed a government break-up during the electoral term of the Chamber of Deputies, presidents were significantly stronger. Secondly, it depends on the real power of parties, that is, their ability to act together as a cohesive parliamentary majority. In most cases, the presidents showed their resolve to play a greater role than a notary, but they often faced a firm parliamentary majority that actually did not allow them to exert greater influence on the GFP. In contrast, the political proximity between the president and parliamentary parties appears difficult to assess, because there has been the public desire of non-partisan or “above-partisan” presidents in Czechia.

Original Classification

The review considers the first attempt in the history of Russian economic thought to give a detailed analysis of informal institutions (IF). It recognizes that in general it was successful: the reader gets acquainted with the original classification of institutions (including informal ones) and their genesis. According to the reviewer the best achievement of the author is his interdisciplinary approach to the study of problems and, moreover, his bias on the achievements of social psychology because the model of human behavior in the economic mainstream is rather primitive. The book makes evident that namely this model limits the ability of economists to analyze IF. The reviewer also shares the author’s position that in the analysis of the IF genesis the economists should highlight the uncertainty and reject economic determinism. Further discussion of IF is hardly possible without referring to this book.

New Classification

The article highlights certain aspects of the discussion on the topic of reductionism vs. holism in the philosophy of medicine. Classic radical reductionism is defeated by the concept of emergence. The s.c. bio-medical point of view on a malady, despite its relevance and clear benefit, is not recognized as universal as its adherents may claim, and it yields to an integral psycho-bio-social model. The author introduces a new classification of holism (vitalistic, social and individualistic) and makes appropriate recommendations to clinicians. It is social holism at the macro level that has proven effective in combating the spread of COVID-19.
