Following a mailbox of comments concerning a letter sent by the Society of Vertebrate Paleontology to journal editors on “Fossils from conflict zones...” dated 21 April 2020 calling for a ban on publications on Burmese amber, it was felt necessary to air some concerns raised for further discussion.

Abstract The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fifth Edition, is available and includes numerous changes that will affect both evaluators who and systems that use the AMA Guides. The Fifth Edition is nearly twice the size of its predecessor (613 pages vs 339 pages) and contains three additional chapters (the musculoskeletal system now is split into three chapters and the cardiovascular system into two). Table 1 shows how chapters in the Fifth Edition were reorganized from the Fourth Edition. In addition, each of the chapters is presented in a consistent format, as shown in Table 2. This article and subsequent issues of The Guides Newsletter will examine these changes, and the present discussion focuses on major revisions, particularly those in the first two chapters. (See Table 3 for a summary of the revisions to the musculoskeletal and pain chapters.) Chapter 1, Philosophy, Purpose, and Appropriate Use of the AMA Guides, emphasizes objective assessment necessitating a medical evaluation. Most impairment percentages in the Fifth Edition are unchanged from the Fourth because the majority of ratings currently are accepted, there is limited scientific data to support changes, and ratings should not be changed arbitrarily. Chapter 2, Practical Application of the AMA Guides, describes how to use the AMA Guides for consistent and reliable acquisition, analysis, communication, and utilization of medical information through a single set of standards.

This monograph is dedicated to the anniversary of the birth of the great Ukrainian world-famous neurophysiologist, biophysicist Academician Platon Grigoryevich Kostyuk. The monograph includes sections written by P.G. Kostyuk and his students who worked directly with him in the department or defended dissertations under his supervision. The monograph was prepared for a long time, so some authors have already passed away, like Platon Grigoryevich himself. The monograph presents memoirs and scientific data of research in modern molecular, cellular and theoretical neurophysiology and biophysics. The chapters are presented mostly in chronological order of his students’ collaboration with Kostyuk. The monograph will be especially useful for specialists in neurophysiology, biophysics, and medicine: scientists, teachers, graduate students, and students involved in biology and medicine.

There is little doubt that the introduction of modern pesticides since the end of the Second World War has enabled a significant increase in the production of many crops during the green revolution, but criticism of the use of pesticides has increased because more people are claiming that their use has resulted in unacceptable adverse impacts on the health of those applying the pesticides or who live near treated farms, as well as more general impacts on the environment. When these modern pesticides were first introduced, countries established registration requirements. These were based on scientific data at that time concerning their toxicity and persistence in the environment, and have been followed to a variable degree, depending on whether individual countries or regions had adequate facilities to assess the data presented by manufacturers.

Background.Due to the prevalence of Vitamin D deficiency as well as the frequency of reconstructive surgical interventions followed by dental implantation, the issue arises concerning the effect of Vitamin D on reparative regeneration of bone and osseointegration of dental implants.The purpose using literature data we are conducting an impact assessment of vitamin D on reparative regeneration of bone tissue, in particular, after oral reconstruction surgeries and dental implantation.Methods.Retrieval, systematization and analysis of scientific data on application of vitamin D supplementation and its effect on reparative regeneration of jaw bone tissue.The conclusions.For the most part, the positive effect exerted on reparative regeneration of jaw bone tissue and osseointegration of dental implants is due to the role of vitamin D in physiological processes evolving in bone tissue, namely maintenance of calcium and phosphate exchange through intestinal absorption and TNF, RANKL (Receptor activator of nuclear factor kappa-B ligand) and consequently differentiation of precursors to osteoclasts into osteoclasts through VDR stimulation (VitaminD Receptor) receptors for further osteogenesis. Also, according to literature data, FGF23 (Fibroblast Growth Factor) protein is a marker of osteoblasts differentiation into osteocytes, it is also known that FGF23 and 1,25(ОН)2D3 are genetically related. FGF23 is the main regulator of both phosphate exchange in bones and metabolism of vitamin D and its metabolites. Besides, indirect anti-inflammatory effect has been observed thanks to inhibition of pro-inflammatory cytokine secretion. Taking into account the abovementioned data, of particular relevance is the definition of serum concentration 25(ОН)D and development of schemes of vitamin D level pre-surgery correction in patients, who have to undergo oral reconstruction surgeries and dental implantation. Mass spectrometry is a promising diagnostic method for determining the level of vitamin D in a body, as it allows to identify the actual amount of vitamin D free from admixture of other steroid hormones. The introduction of this method into clinical practice will allow to monitor the level of vitamin D in patients, receiving reconstructive and rehabilitative treatment.
