Zaufanie do prawa jako wartość i jego ochrona w porządku prawnym państwa

2023

The article presents the issue of trust in law as one of the fundamental values of a rule-of-law state. The analysis of the court rulings conducted in the first part of the article indicates the principle of a democratic rule-of-law state as a basis for distinguishing substantive and formal components of trust in law. Further considerations of the article focus on showing the change of law, in particular its transition from repressive law to responsive law, and the possible effects of this change on the paradigm of trust established in a democratic ruleof-law state. The effect of these transformations, as indicated by the considerations presented, affects the perception of the authority of …

The influence of infective dose, nutrient availability and coinfection on virulence of Flavobacterium columnare : implications of intensive aquacultu…

2016

Ecological factors are known to affect disease dynamics and even lead to disease emergence. Especially in opportunistic, environmentally transmitted pathogens, the environment may significantly contribute to pathogen virulence. Intensive farming, including aquaculture, has been suggested to create conditions favouring development of highly virulent pathogens. At Finnish fish farms, epidemics caused by opportunistic Flavobacterium columnare have been constantly increasing in their prevalence and severity since the 1980’s. Yet, factors behind the increased virulence of the pathogen and their mechanisms of action have largely remained unsolved. In this thesis, I explore the effects of infectio…

Facilitators of and Barriers to Sustainable Development in Small and Medium-Sized Enterprises: A Descriptive Exploratory Study in Romania

2021

In the context of growing concerns regarding the deterioration of the environment and the increase in social inequalities, the concept of sustainability emerged as a response of companies, in order to contribute to community goodwill. The drivers and obstacles for the businesses engaging in sustainable policies have been explored at large by scientific literature. However, research gaps were observed, namely regarding SMEs, that tend to have a less formal and more fragmented approach to sustainability. The goal of our study is to determine the main barriers and facilitators for sustainability that Romanian SMEs face, and the connections between them and with the firms’ characteristics. Our …

The efficacy of two immunostimulants against Flavobacterium columnare infection in juvenile rainbow trout (Oncorhynchus mykiss).

2009

Abstract Bacterium Flavobacterium columnare is the causative agent of columnaris disease in many wild and farmed fish species. Immunostimulants are used with success in aquaculture against many pathogens, but the ability to improve innate resistance to columnaris disease has not been studied. Fingerling rainbow trout were treated with two immunostimulants, yeast β-glucan and β-hydroxy-β-methylbutyrate (HMB). Selected innate immune function parameters, the production of reactive oxygen species (ROS) by whole blood and by isolated head kidney leukocytes, plasma lysozyme activity and complement bacteriolytic activity, were determined to assess the immune status of fish. The fish were then bath…

Staphylococcus epidermidis biofilmu veidošana un rezistences pret meticilīnu noteikšana, lietojot fenotipiskās un molekulāri bioloģiskās izmeklēšanas…

2018

Staphylococcus epidermidis ir veselas cilvēka ādas un gļotādas dabiskās mikrofloras sastāvdaļa, kas ir viens no visbiežāk sastopamajiem cilvēka mikrobioma pārstāvjiem. Epidermālais stafilokoks ir oportūnists, kas saimniekorganismam spēj kolonizēt gan ādu, gan gļotādu. Kaut arī S. epidermidis piemīt mazāk virulences faktoru, nekā radiniekam S. aureus, epidermālais stafilokoks ir kļuvis par vienu no visbiežāk izolētajiem koagulāzes negatīvajiem stafilokokiem intrahospitālajā vidē. Tomēr neskatoties uz to, ka epidermālajam stafilokokam ir mazāk virulences faktoru, tas ir kļuvis par nopietnu un komplicētu problēmjautājumu gan ārstniecības iestādēm, gan sabiedrības veselībai kopumā. Pētījuma mēr…

Pneumococcal HxxHxH triad – Copper(II) interactions – How important is the ‘x’?

2019

Abstract PhtA, a Streptococcus pneumoniae polyhistidine triad protein, which contributes to virulence by interacting with components of the immune system, by being involved in adherence of bacteria and in Zn(II) uptake, contains five copies of the HxxHxH sequence. Since this motif is also present in numerous Cu(II) binding proteins, we decided to focus on the bioinorganic chemistry of copper(II) with three of such PhtA repeats, in order to understand which of the PhtA triads binds Cu(II) with the highest affinity and explain if Cu(II) would be able to outcompete Zn(II) from its native binding site under physiological metal concentrations.

Intestinal helminth fauna of striped dolphins (Stenella coeruleoalba) in the western Mediterranean: No effects of host body length, age and sex

2014

The intestine of 52 (28 males and 24 females) striped dolphins (Stenella coeruleoalba) from western Mediterranean waters was examined for helminths. Animals were found stranded along the Spanish coasts during the morbillivirus epizootic in 1990. In accordance with observations from other pelagic tetrapods, including cetaceans from other geographical regions, the intestinal helminth community was depauperate. Four helminth species were found: three tetrabothriid cestodes, Tetrabothrius forsteri (prevalence: 96.2%; mean intensity [95% CI]: 47.4 [34.4–68.2]), Trigonocotyle globicephalae (9.6%; 1.8 [1.0–2.2]), and Strobilocephalus triangularis (23.1%; 5.3 [2.9–10.2]), and immature individuals o…

Exploitation competition between hole‐nesters ( Muscardinus avellanarius , Mammalia and Parus caeruleus , Aves) in Mediterranean woodlands

2005

Data from a long-term study (1993-2003) using artificial nest-boxes, were analysed to examine competition for nesting between blue tit Parus caeruleus and common dormouse Muscardinus avellanarius in Sicily. Occupation rates and the reproductive biology of the blue tit in sample woodlots outside the distribution area of the common dormouse were used as a control in sample areas where the two species were syntopic. A selection test showed that the two species, when living in syntopy, actively chose the small nest-boxes, thus overlapping in the use of the same spatial resource. The experimental exclusion of the common dormouse from nest-boxes caused an increase of blue tit occupation rate. Onc…
