Opis:
Common use of venipuncture on upper and lower limbs for diagnostic purposes (such as coronarography or arteriography), and also during the course of treatment (angioplasty), very often bares a complication in the form of pseudoaneurysms. According to various reports, the incidence of pseudoaneurysms ranges from 0.005% to 0.5% of all vascular procedures requiring arterial cannulation (Common Femoral Artery, Brachial Artery, Radial Artery). The use of Bio Trombina® 400 in the embolization of pseudoaneurysms allows minimally invasive and effective treatment. The aim of the study was to evaluate the efficacy of pseudoaneurysm embolization with the use of Trombina 400, authors’ own experience. Material and methods. In the years 2011 - 2013, the authors of this study performed 38 vascular interventional procedures involving pseudoaneurysms as complications of venipuncture in upper and lower limbs for diagnostic and treatment purposes. All procedures involved the direct injection of thrombin into the chamber of the pseudoaneurysm under the guidance of USG Doppler (6.2 MHz linear head). 34 cases presented single chamber pseudoaneurysms while 4 cases involved multi- chamber pseudoaneurysms, which required several thrombin reinjections (Bio Trombina® 400) into each of the chambers. Pseudoaneurysm maximum size of 4 cm was set as an inclusion criterion for the embolization procedure. Furthermore, all pseudoaneurysms with a significantly wide tract in transverse dimensions were treated as an exclusion criterion because of high risk of the peripheral arteries embolization. Results. Initial success was observed in 36 patients (94.73%) in the first day after the procedure, 1 patient (2.63%) underwent thrombin reinjection procedure in the second day after the first embolization. Another patient (2.63%) underwent an open procedure in which the Common Femoral Artery was accessed, the clot evacuated, and CFA was sutured with continuous suture Prolene 6-0. Conclusions. 1. Embolization of pseudoaneurysms with USG Doppler-guided thrombin injection is an effective course of treatment for complications of cannulation. 2. The safety of pseudoaneurysm embolization depends on a surgeon’s experience. It is also crucial to keep in mind the inclusion and exclusion criteria for this type of procedure (the size of a pseudoaneurysm, the width of its base). 3. Furthermore, its cost effectiveness and short hospitalization period make pseudoaneurysm embolization an effective and valuable alternative to the classic approach.

Opis:
The article focuses on the issue of trust development in low-trust societies. Based on a review of the existing literature, we discuss the types of trust as well as mechanisms of trust creation. On this basis, we propose a dynamic four-stage model of trust development. The model is based on the assumption of gradual accumulation of various trust forms on a social level. The article also discusses the implications of the model as well as the possible future routes of empirical research it may open.

Opis:
Sekwencje LINE należą do grupy ruchomych elementów genetycznych w genomach eukariotycznych. Rozprzestrzeniają się w nich według modelu "kopiuj i wklej" za pośrednictwem RNA i odwrotnej transkryptazy. W genomie ludzkim zlokalizowano ponad 500 tys. kopii tych elementów, niemniej nieliczne z nich zachowują swoją aktywność. Jej konsekwencją jest destabilizacja struktury genomu powodująca m.in. zaburzenia ekspresji genów, alternatywnego splicingu czy aktywację alternatywnych promotorów. Transpozycja LINE to proces aktywny głównie we wczesnych stadiach embriogenezy, natomiast w prawidłowych komórkach somatycznych tłumiona jest za pomocą mechanizmów epigenetycznych. Zmiany w poziomie metylacji DNA tych elementów są jednym z głównych wskaźników ich aktywności wiązanej z licznymi chorobami genetycznymi. Najpełniej opisane zostały zależności między aktywnością LINE a różnymi postaciami nowotworów.
LINE transposons (Long Interspersed Nuclear Elements) are mobile, endogenous genetic elements widespread in eukaryotic genomes. Their ability to spread out with help of reverse transcriptase by using RNA intermediates indicates that they belong to autonomous retrotransposons. Original element is transcribed, then RNA undergoes reverse transcription and as a DNA fragment it is inserted into another part of the genome. Despite of the presence of over 500.000 of their copies in the human genome, majority of LINEs became inactive due to structural changes during the process of evolution. Sequences that retained their original function, play an important role in organization and functioning of genomes. Their activity results in destabilization of a genome structure, as a result of de novo insertions of LINEs and changes caused by homologous recombination between them. They can cause changes in the level of gene expression by interfering with alternative splicing (resulting in exon skipping or selecting cryptic splice sites), generating polyadenylation signals or providing alternative promoters. LINE retrotransposition is active mainly during the early stages of embryogenesis. In normal somatic cells this process is silenced by epigenetic mechanisms. Changes in DNA methylation levels of these elements is one of the main indicators of their activity associated with multiple genetic diseases. Correlations between LINE activity and multiple forms of neoplasms are mostly described in this paper.

Opis:
Purpose: The development of digital technology is one of the most important factors driving changes in consumer behavior in the 21st century. Today, the sharing economy covers more and more areas of consumers' daily lives. Using online apps to exchange, sell, buy or rent clothes has become one of the most popular ways of consuming fashion around the world. The main objective of this paper is to assess the importance and estimate the impact of the determinants (motives and unpleasant user experience) of providers' engagement in collaborative fashion consumption (CFC). Design/methodology/approach: The study was conducted using an online survey with 420 respondents in Poland - users (providers) of CFC platforms. A confirmatory factor analysis (CFA) and structural equation model (SEM) was performed using AMOS 21.0 version. The conducted research allowed to identify the importance and to determine the influence of examined factors on attitudes toward CFCs and willingness to use CFC apps in the future. Findings: Economic motives did not outperform non-economic motives to participate as a provider in CFC. Pragmatic motives were by far the most important determinants of fashion sharing. Environmental factors are an important reason for providers to participate in CFC but they may not be a direct motivation for CC participation. Social motives recorded the lowest average importance rating in the context of participation in CFC. Unpleasant user experience negatively influence both the attitudes toward using CFC apps and the willingness to use them in the future Research limitations/implications: The research was conducted only on Polish users, so due to cultural differences, the meaning and impact of the motives of using these apps may be different in other countries. Due to the method of sampling and sample size, the results cannot be treated as representative for the population of Polish users of CFC platforms. Future research could include conducting cross-country research and one may attempt to broaden the scope to include other categories of motives. Future research could also extend the scope of unpleasant user experience with other factors. Practical implications: The results of research on the motives of users' use of CFC apps should be useful for enterprises in the context of designing activities in the field of marketing communication. Originality/value: The paper fills a research gap in the field of research on the determinants of polish providers' engagement in collaborative fashion consumption (CFC).

Opis:
In recent years, there has been a noticeable increase in consumer interest in participating in the sharing economy. One of the markets in which this is particularly visible is the clothing market. Dynamic technological progress and the virtualisation of life have contributed to the creation of applications with which consumers can buy, exchange or borrow clothes. The use of this type of application is treated as a manifestation of sustainable consumption. The main aim of the article is to determine the influence of selected motives on the attitudes towards these applications and their use. The article discusses the results of the research conducted in 2021 on a sample of 412 respondents. Confirmatory factor analysis and structural equation modelling were used in the process of analysing the results. The research results suggest that the most important motives for using the discussed applications were economic and utility, with their impact on attitudes towards these applications and the willingness to use them confirmed. Social motives turned out to be the lowest-rated group of determinants. Moreover, their negative impact on both attitudes towards the application and the willingness to use it was confirmed. Ecological motives turned out to be relatively important determinants of using the discussed solutions. Their influence on attitudes towards the application and consumption behaviour was confirmed.

A rare case of distant metastasis to spinal column – lumbar vertebra (L5) – from laryngeal cancer was reported. It must be noted that in 10 % of cases metastases to vertebral column are first symptom of a neoplastic disease and sixty-five percent of patients with advanced cancer present bone metastases. Metastatic involvement of the bone is one of the most frequent causes of pain in cancer patients and represents one of the first signs of widespread neoplastic disease. Nevertheless metastases to lumbar vertebral column from laryngeal cancer is very rare. In presented case MRI and CT were performed to confirm metastasis. Laryngological examination revealed tumor of a right part of larynx – squamous cell carcinoma (G2) in histopathological examination. The patient was qualified to palliative radiotherapy and still is under laryngological observation.

Purpose: In this article we focus on the issue of organizational control in its bureaucratic and cultural forms. Methodology: This research uses exploratory case study analysis of Matsushita Konosuke’s management style of in the early years of the Panasonic Corporation. Findings: First of all, we fi nd that despite the impressive body of knowledge accumulated over the years, some questions concerning the relationship between two modes of control and their changes over time still remain unanswered. As a result of case study analysis we put forward an original model illustrating the relationship between bureaucratic and cultural modes of control over stages of the organization life cycle. Research implications and limitations: Implications of the study consist of prescriptions on how to successfully exert control by combining formal and informal measures. Main limitations of the study are related to its generalizability. Originality: Originality of the study results both from putting forward a new theoretical models and using original historical case of Panasonic Corporation.

Starzenie się ludności coraz bardziej widoczne na poziomie mikro (rodziny) i makro (całego społeczeństwa) wymaga dogłębnego poznania i opisania również ze względu na zwiększające się znaczenie segmentu konsumentów seniorów w gospodarce. Obszar badawczy dotyczący zachowań konsumentów jest bardzo szeroki. W artykule podjęto problem rozpoznania istoty/wymiarów innowacyjności w zachowaniach ludzi starszych. Innowacyjność, jako cecha osobowości człowieka, wykazuje zróżnicowane nasilenie, odzwierciedlając się w odmiennych zachowaniach wobec nowych zjawisk. Celem artykułu jest zaprezentowanie wybranych aspektów dotyczących poziomu innowacyjności w zachowaniach konsumentów seniorów.
The ageing of the population, which is increasingly visible at the micro level (family) and macro level (the whole of the society), requires in-depth exploration and description, also due to the increasing importance of the segment of senior consumers in the economy. The area of research on consumer behaviour is very broad. The article addresses the issue of recognizing the dimensions of innovativeness in the behaviour of the elderly. Innovation, as a feature of the human personality, manifests itself in varying degrees, reflecting different behaviours towards new phenomena. The aim of this article is to present selected aspects of the research identifying the level of innovation in senior consumers’ behaviour.

Opis:
This paper presents the debate about Japanese management in a chronological order and puts forward a new definition of the concept. As a result of literature review, we distinguished four major periods of the debate i.e. the birth of Japanese management concept (1950’s -1960’s), the peak of popularity (1970’s – 1980’s), critics and appropriation period (1990’s) and the period of dispersion (since 2000’s). The main conclusion from the review is that the current debate about the Japanese management is extremely dispersed and requires new unifying definition. We therefore put forward new, more flexible definition of Japanese management as a dynamic, multilevel and contingent concept.

Opis:
Purpose: This study argued that desipite what the content of the debate might suggest, there is a conflict between the two concepts of rigour and relevance and their actual relationship is a symbiotic one. Drawing on a definition of symbiosis, the study showed that the concepts of rigour and relevance are actually two separate “organisms” that are bound by a long term relationship that benefits both sides. Methodology: The study reviewed selected literature concerning rigour and relevance and presented the historical development of the debate and theoretical models of the relationship between the two concepts. Implications: The implications were presented from a PhD student’s perspective and included suggestions on how to approach the issues of rigour and relevance in the research project and how to cope with their seemingly conflicting nature. Originality: The originality of this study resulted from approaching the issue of rigour and relevance from a biology perspective and extending the definition of symbiosis to the relationship between the two concepts.
