#1
REVIEW
Anna Piotrowska, Wanda Pilch, Łukasz Tota, Gabriel Nowak
Currently, chromium is probably the most controversial transition metal. In recent publications it is clearly stated that it is not an essential micronutrient and should be considered to have a pharmacological effect. Conflicting scientific reports along with a huge amount of dietary supplements, as well as dietary and sports nutrients available on the market have prompted the authors to investigate the available information on the range of possible application, efficacy and safety of products containing salts or chelates of chromium III...

REVIEW
Karol Bukowski, Katarzyna Woźniak
Genetic polymorphism is associated with the occurrence of at least 2 different alleles in the locus with a frequency higher than 1% in the population. Among polymorphisms we can find single nucleotide polymorphism (SNP) and polymorphism of variable number of tandem repeats. The presence of certain polymorphisms in genes encoding DNA repair enzymes is associated with the speed and efficiency of DNA repair and can protect or expose humans to the effects provoked by xenobiotics. Chemicals, such as lead, arsenic pesticides are considered to exhibit strong toxicity...

BACKGROUND: Thermoluminescent detectors, type MTS-6, containing isotope <sup>6</sup>Li (lithium) are sensitive in the range of thermal neutron energy; the <sup>239</sup>Pu-Be (plutonium-and-beryllium) source emits neutrons in the energy range from 1 to 11 MeV. These seemingly contradictory elements may be combined by using the paraffin moderator, a determined density of thermal neutrons in the paraffin block and a conversion coefficient neutron flux to kerma, not forgetting the simultaneous registration of the photon radiation inseparable from the companion neutron radiation...

A 45-year-old male patient was admitted to the Regional Poison Center because of poisoning with dimethyloaniline contained in a toxic resin-curing dimethyl aniline-based formulation ingested inadvertently. Intoxication happened at workplace. The patient was then transferred to the Toxicology Clinic, where he stayed for 3 weeks. During the hospitalization, the primary method of treatment involved administration of methylene blue, which is the antidote of choice in such cases. During the intensive care and treatment of the patient massive intravascular hemolysis was seen...

BACKGROUND: The aim of the study was to evaluate the influence of education, marital status, employment status and place of residence on mortality in the working age population of Poland in 2002 and 2011. MATERIAL AND METHODS: All deaths of Poland's inhabitants aged 25-64, in 2002 (N = 97 004) and 2011 (N = 104 598) were analyzed. For individual socio-economic groups standardized mortality rates (SDR) per 100 000 and rate ratio (RR) were calculated. RESULTS: In the group of economically inactive men SDR decreased from 2244...

BACKGROUND: Self-efficacy refers to different spheres of human functioning and to different tasks, including teaching activity. It is regarded as an important personal resource related to coping with stress. This paper was aimed at presenting psychometric properties of the Norwegian Teachers Self-Efficacy Scale (NTSES), related to these beliefs in the group of teachers. MATERIAL AND METHODS: Psychometric properties of the scale were evaluated on the basis of the data obtained from 404 teachers of elementary and middle schools...

BACKGROUND: One of the numerous sub-areas of interventional radiology is the use of X-rays in gastroenterology. X-ray fluoroscopy is applied in therapeutic procedures, including endoscopic retrograde cholangiopancreatography (ERCP) that is frequently performed. The ERCP procedure is aimed at imaging the pancreatic duct and biliary tracts. MATERIAL AND METHODS: In this paper radiation risk to the gastrenterologist performing ERCP procedures was investigated. The procedures were performed by a single gastroenterologist in the ERCP Laboratory, University Clinical Hospital Military Memorial Medical Academy - Central Veterans' Hospital in Łódź, Poland...

REVIEW
Daria Pakulska, Sławomir Czerczak
This article deals with health risks resulting from exposure to zinc and its inorganic compounds in industry. The main source of zinc exposure are fumes generated during thermal and chemical processes, mainly zinc oxide fume formed by immediate oxidation of metallic zinc vapor formed during high-temperature processes, as well as dust generated during the mechanical processing of zinc-containing materials. It is recognized that zinc ions are responsible for health effects of exposure to dust/fumes of the majority of zinc compounds, and the final effect of exposure depends on the degree of dispersion of dusts/fumes suspended in the air...

BACKGROUND: The article presents the mutual relations between the components of work ethic and the strategies of coping with stress used by employees of different branches. MATERIAL AND METHODS: Work ethic was presented as a syndrome of the following attitudes: perceiving work as a moral value, treating work as a central value in life, and the belief in the importance of hard work that leads to success. This ethic also consists of the following components: unwillingness to waste time, disapproval of spare time (anti-leisure), willingness to delay gratification, willingness to act honestly at work (morality/ethic), and being independent (self-reliance)...

BACKGROUND: Of many diseases and disorders of the nervous system Parkinson's disease (PD) deserves a particular attention for its specific effects having an impact on the ability to undertake different forms of professional and economic activities. Due to the constantly growing incidence rate and the lowering age of patients, PD is becoming more and more serious social problem. The aim of this study was to determine the effects of professional work and physiotherapy on the quality of live in people with Parkinson's disease...

Hairdressing is one of the most developing branch of the service industry in Poland. Providing representatives of this occupational group with preventive health care services it should be remembered that they are at risk of skin and respiratory diseases, which occur due to a quite frequent exposure to harmful agents in the work environment of hairdressers and hairdressing apprentices. Interestingly, a much lower number of researches concentrate on respiratory symptoms than on skin disorders in hairdressers...

BACKGROUND: Glutamate (Glu) and γ-aminobutyric acid (GABA) are the main neurotransmitters in the central nervous system for excitatory and inhibitory processes, respectively. Monitoring these neurotransmitters is an essential tool in establishing pathological functions, among others in terms of occupational exposure to toxic substances. MATERIAL AND METHODS: We present modification of the HPLC (high-performance liquid chromatography) to the UPLC (ultra-performance liquid chromatography) method for the simultaneous determination of glutamate and γ-aminobutyric acid in a single injection...

BACKGROUND: There are no available data on the health consequences that may result from the synergistic effects of electromagnetic fields (EMF) and stress. Understanding the mechanisms of the simultaneous exposure will make it possible to develop procedures to minimize adverse health effects in professionals using mobile phones. MATERIAL AND METHODS: A questionnaire survey was conducted in 600 randomly selected people to obtain data on their health status and the prevalence of subjective symptoms related to the mobile phones using...

BACKGROUND: Over the years it has been assumed, that the greater the number of pilot flight hours, the better the development of problem-solving skills among pilots. Research suggests, however, that the problem is more complex than that. Not only one's experience is of importance - temperament, aggression and risk may also affect the decision-making process under stressful conditions. MATERIAL AND METHODS: We examined 97 male pilots of passenger planes, who had flew ATRs, Boeings, Airbuses, Embraers, and Saabs...

Agnieszka Springer, Karolina Oleksa
BACKGROUND: Nowadays more and more employees are required to perform emotional labor (EL) which means that they need to express emotions set by the organizational procedures, simultaneously masking the true feelings. Employees, while performing emotional labor, choose between one of the two strategies (surface acting or deep acting) and this leads to e.g., burnout. As the performance of emotional labor and its consequences depend on the specification of work and chosen strategy, it was assumed that the consequences of EL may be different for workers in various occupations...
