Opis:
Introduction. On 11 March 2020, the Director-General of the World Health Organization (WHO) announced COVID-19 (Coronavirus Disease 2019) as a global pandemic Currently, no vaccines are available and there is little evidence of the efficacy of potential therapeutic agents. Furthermore, there is presumably no pre-existing immunity in the population to the new coronavirus, and it is as-sumed that everyone in the population is susceptible. Objective. The aim of the procedures described in the article is to minimize the risk of human-to-human transmission of the SARS-CoV-2 (Severe acute respiratory syndrome – coronavirus 2) virus during procedures carried out in endoscopic laboratories. Brief description of the state of the art. SARS-CoV-2 infection can be asymptomatic, cause severe pneumonia, or lead to death. Symptoms of COVID-19 range from none (asymptomatic) to severe pneumonia and it can be fatal. Case studies to-date indicate that this infection causes a mild illness (i.e. pneumonia or mild pneumonia) in approximately 80% of cases, and most cases recove; 14% have a more severe illness, 6% experience a critical illness. The vast majority of the most serious illnesses and deaths have occurred among the elderly and people with other chronic underlying diseases. Average progression times include: • in mild cases: from the onset of symptoms to recovery in almost 2 weeks; • in severe cases: from the onset of symptoms to recovery in 3–6 weeks, and from symptoms to death in 2–8 weeks. Conclusions. Special precautions should be taken and procedures followed when performing invasive medical procedures in endoscopic laboratories in patients with specific or clinically probable SARS-CoV-2 infection. This article contains up-to-date information as at 04/04/2020.

Opis:
Introduction. Prion diseases are slow-acting, neurodegenerative diseases found in humans and many species of animals. Although they occur very rarely in humans, currently, an increase in this type of disease is being observed, probably as a result of exposure to infectious prions causing BSE disease in cows. Objective. The aim of the procedures described in the article is to minimize the risk of human-to-human transfer of all forms of transmissible spongiform encephalopathy, including variant CJD (vCJD) by contaminated medical equipment. Brief description of the state of knowledge. All diseases caused by prions, referred to as transmissible spongiform encephalopathies, are fatal. They are characterized by a long development period (up to several decades). Enormous problems are connected with the risk of transferring prions from patient to patient on the surface of instruments used in medical procedures. Laboratory tests indicate that standard disinfection and sterilization procedures may be insufficient to completely remove infectious proteins from contaminated instruments. One of the methods of infection prevention involves taking equipment used for surgery within the brain, tonsils or appendix, into quarantine until biopsy results of these organs have been received that exclude, as far as possible, asymptomatic carriage of prions. Conclusions. Whenever possible and justified, disposable-use instruments should be used for invasive surgery in patients with definite, clinically probable cases of CJD (vCJD). After use, these instruments should be incinerated.

Opis:
Introduction. The operating theatre is one of the most important places in a hospital. Due to the presence of numerous reservoirs of microorganisms and the invasiveness of surgical procedures it is necessary to ensure high hygiene standards in these locations. Objective. The aim of the study was to carry out a qualitative assessment of the microbiological cleanliness of the surfaces and equipment in an operating theatre. Materials and method. The results of microbiological tests of the surfaces and equipment of the Children’s Operating Theatre in Clinical Provincial Hospital No. 2 in Rzeszów, southeast Poland, during 2007–2012 were reviewed retrospectively. Results and conclusions. For the analysis, a total of 1,819 swabs were collected, of which 1.05% were positive. Positive results were obtained mainly from samples taken from moist places (57.9%). Among the microorganisms isolated, Gram- negative bacteria constituted the majority (57.9%), Pseudomonas bacteria were found most frequently (31,6%). Isolated microbes can be the etiological agent of nosocomial infections.

Opis:
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is one of the most important foliar diseases of cereals. Infection by this pathogen on triticale has intensified in Poland in the last few years. In this study we examined resistance to powdery mildew in triticale hybrids possessing resistance genes Pm4b and Pm6 introduced from common wheat. The materials tested were hybrids derived from triticale crosses with common wheat cultivars carrying the desired resistance genes. The presence of the transferred genes was reflected in increased field resistance and shown by the use of molecular markers. The paper discusses the potential introduction of the genes to improve powdery mildew resistance.

Opis:
Paper presents the results of investigations of the influence of the tensile stresses on magnetic characteristics of $Fe_{80}B_{11}Si_{9}$ amorphous alloy in as quenched and annealed state. For the tests, a special methodology of application of uniform tensile stresses to the ring shaped sample was developed. Due to special non-magnetic pads, the magnetizing and sensing coils can be wound around the core. Experimental results indicate high stress sensitivity of $Fe_{80}B_{11}Si_{9}$ alloy in both as-quenched and annealed state. Permeability of the core decreases over 64% and 58% for as-quenched and annealed core respectively, especially for lower values of the amplitude of magnetizing field.

Opis:
Information about magnetoelastic properties of newly developed amorphous magnetic alloys is very important from practical point of view, especially in the case of high permeability materials such as the Fe₆₁Co₁₉Si₅B₁₅ amorphous alloy. In the case of such materials, effect connected with the influence of external stresses on the magnetic properties of the alloy should be tested. This paper presents experimental results of the magnetoelastic properties investigation of the Fe₆₁Co₁₉Si₅B₁₅ amorphous alloy, annealed without magnetic field as well as in the magnetic field. Such thermo-magnetic treatment generated anisotropy has significant influence on the total free energy of magnetic material. In the magnetoelastic investigation, the compressive stress was applied to the ring shaped core, perpendicularly to the magnetizing field direction. Due to the fact, that cores with closed magnetic circuits were used, demagnetization did not change the balance of total free energy in the material.
