<abstract xmlns="http://www.w3.org/1999/xhtml"> The article demonstrates use of underwater remotely operated vehicles during an underwater visual inspection of a sunken vessel. The presented tasks were carried out in the course of underwater works performed from a Polish navy rescue vessel on the fishing boat WŁA-127. The discussed examples include a visual inspection of the sunken vessel and the support offered to Polish Navy rescue divers as they carried out underwater works.</abstract>

The Support of Underwater Works with the Use of Remotely Operated Vehicles On the Example of Works Conducted On the Wreck of the Fishing Boat WŁA-127

<abstract xmlns="http://www.w3.org/1999/xhtml"> Any stay in an environment with an increased oxygen content (a higher oxygen partial pressure, pO2) and an increased pressure (hyperbaric conditions) leads to an intensification of oxidative stress. Reactive oxygen species (ROS) damage the molecules of proteins, nucleic acids, cause lipid oxidation and are engaged in the development of numerous diseases, including diseases of the circulatory system, neurodegenerative diseases, etc. There are certain mechanisms of protection against unfavourable effects of oxidative stress. Enzymatic and non-enzymatic systems belong to them. The latter include, among others, heat shock proteins (HSP). Their precise role and mechanism of action have been a subject of intensive research conducted in recent years. Hyperoxia and hyperbaria also have an effect on the expression and activity of nitrogen oxide synthase (NOS). Its product - nitrogen oxide (NO) can react with reactive oxygen species and contribute to the development of nitrosative stress. NOS occurs as isoforms in various tissues and exhibit different reactions to the discussed factors. The authors have prepared a brief review of research determining the effect of hyperoxia and hyperbaria on HSP expression and NOS activity.</abstract>

The Influence of Hyperoxia On Heat Shock Proteins Expression and Nitric Oxide Synthase Activity – the Review

<abstract xmlns="http://www.w3.org/1999/xhtml"> Service on a submarine is the most stressful and psychologically challenging form of military service. It is characterised by specific living and sanitaryepidemiological conditions which are far from typical. This work is based on the analyses of reports formulated from research conducted by a working environment laboratory, and on the control protocols of the sanitary supervision and control team (WOMP) Gdynia, from the Kobben submersible vessels in the years 2014 and 2015. Military Centres of Preventive Medicine hold supervision over Military Units pursuant to generally applicable regulations in the civil environment and standardised NATO norms. Measurements concern the level of noise, mechanical vibrations, chemical agents, electromagnetic radiation, physiochemical and biological water and kitchenware tests. The objective of the research is to evaluate the service conditions on a submersible vessel with regard to sanitary-epidemiological aspects such as exposure to infectious and occupational diseases. In selected stations, the conducted measurements indicate an increased level of noise, electromagnetic radiation and excess quantities of bacteria colonies on kitchenware.</abstract>

The Evaluation of Sanitary-Epidemiological Service Conditions On a Submarine

<abstract xmlns="http://www.w3.org/1999/xhtml"> The problem of oxygen toxicity, and its effect on the nervous system, is an important topic with regard to the application of oxygen and breathing mixes in the pursuit of diving, as well as in the light of the striking synergy between the effects of oxygen and ionising radiation. Studies on the level of lipid peroxides were performed on rat brains. The animals were subjected to exhaustive physical strain in a pressure chamber and oxygen at the pressure between 0-3 atm for the period of 25-60 minutes. Parallel research was conducted on rested animals. Following the dissection, the brain was homogenised and the levels of lipid peroxides were determined using the Wollman method with TBA. In animals subjected to physical effort over the specified time, no deviations in the levels of lipid peroxides were observed in comparison to the control group. An increase in lipid peroxide level was noted in rats manifesting oxygen toxicity symptoms. On the basis of the above findings, the authors presume that the growth of lipid peroxides in the brain in cases subjected to hyperbaric oxygenation should be recognised as a far-reaching harmful effect of oxygen, occurring after enzymatic damage and the violation of cellular antioxidant protection. At low oxygen overpressures, no deviations in the levels of lipid peroxides were noted as compared to the control group.</abstract>

The Effect of Hyperbaric Oxygen Therapy On the Level of Lipid Peroxides in Rat Brains

<abstract xmlns="http://www.w3.org/1999/xhtml"> Unexpected, abrupt death is always a great tragedy, both for a victim, as well as, for their family, friends, society or even country. However, death as a result of a suicide always seems to be unnecessary and difficult to accept by relatives. Every 40 seconds someone dies on the globe due to a kind of an auto-destruction act. Out of all suicides, the biggest group are adult men, frequently with mental disorders, who commit suicide by hanging themselves. The only suicide method where women are almost on the par with men is drowning (by many authors referred to as death by drowning).</abstract>

Polish Hyperbaric Research

Why subscribe and read  In the journal one can find a wide range of original, high-value scientific articles from fields unpublished in other journals, which are hyperbaric technology and hyperbaric medicine. Through the publication of a broad base of results of research on major and related research fields of the magazine, Polish Hyperbaric Research provides an excellent platform for the exchange of ideas between scientists, experts and users of the technology. This is particularly valuable idea with the extremely scarce representation of magazines dealing with this issue in Europe (2) and around the world.  A multi Scientific Council representing both the main directions of scientific interest of the magazine and related fields, with affiliations in many countries of the world, whose members are employed in scientific centers, institutes and research centers guarantees a high level of knowledge, but above all an opportunity to present the results of multicenter multidisciplinary research.  The contents of each new issue of the magazine, in addition to original research papers is complemented by descriptions of cases and general outlook works -which is an excellent source of systematic knowledge for recipients - practitioners, students, etc.  The Polish Hyperbaric Research also publishes messages about events relevant to the research community.  Polish Hyperbaric Research is the journal owned and published by the Polish Hyperbaric Medicine and Technology Society.   Why submit  Our magazine prides itself on the fact that the priority of the Editorial Board is a quick and constructive process of reviewing and short deadlines between sending of the article, approval for publication and print. Editing is possible for both English-speaking and non-English speaking authors.  The degree of rejection of work of the mainstream topic, which the PHR is engaged in is not more than 25%.  The articles accepted for printing can contain colorful illustrations and charts as well as the publications of large volume, not accepted in most scientific journals.  Publication fee is 120 PLN per two pages A4, in special cases it is possible to skip the fee. Payment in PHR is charged only from authors after they'r article is alredy publicated. We dont charge fee for the act of processing the article. The amount of payment changes every year. The articles we order are free of charge.  In addition, PHR as the only Polish and one of the few scientific journals in the world gives annual award for science students for successful debut on the pages of the quarterly. This prize is awarded to the author who first published the material in a scientific journal which has achieved good marks in reviews.  It is an encouragement to further fruitful activity for young scientists, who begin their adventure with science. The prize is awarded annually by the decision of the members of the Editorial Committee and the Scientific Council in the form of a commemorative statuette and a promise of free publication of the following article. The award ceremony takes place during the inauguration of the annual scientific conference of the publisher i.e. Polish Society of Hyperbaric Medicine and Technology.
